Attention and distraction

وَأَنذِرۡهُمۡ يَوۡمَ ٱلۡحَسۡرَةِ إِذۡ قُضِيَ ٱلۡأَمۡرُ وَهُمۡ فِي غَفۡلَةࣲ وَهُمۡ لَا يُؤۡمِنُونَ

for they are heedless and do not believe

ٱقۡتَرَبَ لِلنَّاسِ حِسَابُهُمۡ وَهُمۡ فِي غَفۡلَةࣲ مُّعۡرِضُونَ

Ever closer to people draws their reckoning, while they turn away, heedless

قُلۡ يَٰٓأَهۡلَ ٱلۡكِتَٰبِ لِمَ تَصُدُّونَ عَن سَبِيلِ ٱللَّهِ مَنۡ ءَامَنَ تَبۡغُونَهَا عِوَجࣰ ا وَأَنتُمۡ شُهَدَآءُۗ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعۡمَلُونَ

Say, ‘People of the Book, why do you turn the believers away from God’s path and try to make it crooked, when you yourselves [should be] witnesses to the [truth]? God is not heedless of anything you do.’

وَإِذَا كُنتَ فِيهِمۡ فَأَقَمۡتَ لَهُمُ ٱلصَّلَوٰةَ فَلۡتَقُمۡ طَآئِفَةࣱ مِّنۡهُم مَّعَكَ وَلۡيَأۡخُذُوٓاْ أَسۡلِحَتَهُمۡۖ فَإِذَا سَجَدُواْ فَلۡيَكُونُواْ مِن وَرَآئِكُمۡ وَلۡتَأۡتِ طَآئِفَةٌ أُخۡرَىٰ لَمۡ يُصَلُّواْ فَلۡيُصَلُّواْ مَعَكَ وَلۡيَأۡخُذُواْ حِذۡرَهُمۡ وَأَسۡلِحَتَهُمۡۗ وَدَّ ٱلَّذِينَ كَفَرُواْ لَوۡ تَغۡفُلُونَ عَنۡ أَسۡلِحَتِكُمۡ وَأَمۡتِعَتِكُمۡ فَيَمِيلُونَ عَلَيۡكُم مَّيۡلَةࣰ وَٰحِدَةࣰۚ وَلَا جُنَاحَ عَلَيۡكُمۡ إِن كَانَ بِكُمۡ أَذࣰ ى مِّن مَّطَرٍ أَوۡ كُنتُم مَّرۡضَىٰٓ أَن تَضَعُوٓاْ أَسۡلِحَتَكُمۡۖ وَخُذُواْ حِذۡرَكُمۡۗ إِنَّ ٱللَّهَ أَعَدَّ لِلۡكَٰفِرِينَ عَذَابࣰ ا مُّهِينࣰ ا

When you [Prophet] are with the believers, leading them in prayer, let a group of them stand up in prayer with you, taking their weapons with them, and when they have finished their prostration, let them take up their positions at the back. Then let the other group, who have not yet prayed, pray with you, also on their guard and armed with their weapons: the disbelievers would dearly like you to be heedless of your weapons and baggage, in order for them to take you in a single assault. You will not be blamed if you lay aside your arms when you are overtaken by heavy rain or illness, but be on your guard. Indeed, God has prepared a humiliating punishment for the disbelievers

وَلَقَدۡ ذَرَأۡنَا لِجَهَنَّمَ كَثِيرࣰ ا مِّنَ ٱلۡجِنِّ وَٱلۡإِنسِۖ لَهُمۡ قُلُوبࣱ لَّا يَفۡقَهُونَ بِهَا وَلَهُمۡ أَعۡيُنࣱ لَّا يُبۡصِرُونَ بِهَا وَلَهُمۡ ءَاذَانࣱ لَّا يَسۡمَعُونَ بِهَآۚ أُوْلَٰٓئِكَ كَٱلۡأَنۡعَٰمِ بَلۡ هُمۡ أَضَلُّۚ أُوْلَٰٓئِكَ هُمُ ٱلۡغَٰفِلُونَ

We have created many jinn and people who are destined for Hell, with hearts they do not use for comprehension, eyes they do not use for sight, ears they do not use for hearing. They are like cattle, no, even further astray: these are the ones who are entirely heedless

وَٱذۡكُر رَّبَّكَ فِي نَفۡسِكَ تَضَرُّعࣰ ا وَخِيفَةࣰ وَدُونَ ٱلۡجَهۡرِ مِنَ ٱلۡقَوۡلِ بِٱلۡغُدُوِّ وَٱلۡأٓصَالِ وَلَا تَكُن مِّنَ ٱلۡغَٰفِلِينَ

[Prophet], remember your Lord inwardly, in all humility and awe, without raising your voice, in the mornings and in the evenings- do not be one of the heedless

Warn them of the day of remorse. The Day of Remorse is the Day of Resurrection. Wretchedness preceded for one group without their having committing disobedience, and felicity for another group without their having done beautiful deeds. The Day of Remorse is the first day in the era of the Beginningless, when it was ruled and decreed that everyone would be given what was suited for him: One would be driven away without any offense, and the other caressed but not because of obedience. For one a robe of elevation was woven without bias, and the other was burned in the fire of severance without iniquity. One was full of joy on the carpet of gentleness and heard the address, “So rejoice in your sale!” [9:111]. The other was in the pit of abandonment with the attribute of deprivation and tasted the venom of “Die in your rage!” [3:119]. Yes, He put into effect the precedent as He knew it, and H

And warn them threaten O Muhammad (s) the disbelievers of Mecca of the Day of Regret namely the Day of Resurrection on which the sinner will regret not having been virtuous in the life of this world when the matter will be decided for them thereupon that they be chastised while they in this world are yet heedless of it and do not believe in it the Day of Resurrection.

Nigh has drawn for mankind the people of Mecca the deniers of the Resurrection their reckoning on the Day of Resurrection yet they are heedless of it disregardful of the preparation required for it by way of embracing faith.

The Virtues of Surat Al-Anbiya' Al-Bukhari recorded that 'Abdur-Rahman bin Yazid said that 'Abdullah said, "Banu Isra'il, Al-Kahf, Maryam, Ta Ha and Al-Anbiya' - they are among the earliest and most beautiful Surahs and they are my treasure." بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ In the Name of Allah, the Most Gracious, the Most Merciful. اقْتَرَبَ لِلنَّاسِ حِسَابُهُمْ وَهُمْ فِي غَفْلَةٍ مُّعْرِضُونَ - مَا يَأْتِيهِم مِّن ذِكْرٍ مِّن رَّبِّهِم مُّحْدَثٍ إِلَّا اسْتَمَعُوهُ وَهُمْ يَلْعَبُونَ - لَاهِيَةً قُلُوبُهُمْ ۗ وَأَسَرُّوا النَّجْوَى الَّذِينَ ظَلَمُوا هَلْ هَٰذَا إِلَّا بَشَرٌ مِّثْلُكُمْ ۖ أَفَتَأْتُونَ السِّحْرَ وَأَنتُمْ تُبْصِرُونَ - قَالَ رَبِّي يَعْلَمُ الْقَوْلَ فِي السَّمَاءِ وَالْأَرْضِ ۖ وَهُوَ السَّمِيعُ الْعَلِيمُ - بَلْ قَالُوا أَضْغَاثُ أَحْلَامٍ بَلِ افْتَرَاهُ بَلْ هُوَ شَاعِرٌ فَلْيَأْتِنَا بِآيَةٍ كَمَا أُرْسِلَ الْأَوَّلُونَ - مَا آمَنَتْ قَبْلَهُم مِّن ق

(And when thou (O Muhammad) art among them and arrangest (their) worship for them�) [4:102]. The teacher Abu �Uthman al-Za�farani al-Muqri� informed us in the year [4]25> Abu Muhammad �Abd Allah ibn Muhammad ibn �Ali ibn Ziyad al-Suddi in the year 363> Abu Sa�id al-Fadl ibn Muhammad al-Jazari in the Sacred Mosque, Mecca, in 304> �Ali ibn Ziyad al-Lahji> Abu Qurrah Musa ibn Tariq> Sufyan> Mansur> Mujahid> Abu �Ayyash al-Zurraqi who said: �We performed the prayer of Zuhr with the Messenger of Allah, Allah bless him and give him peace, upon which the idolaters exclaimed: �They were in a vulnerable situation, why did we not attack them by surprise?� Then they said: �There shall come another prayer which is more beloved to them than their own fathers, which is the midafternoon (�Asr) prayer�. Gabriel, peace be upon him, then came down with these verses between the Zuhr and the �Asr prayers. (

And remember thy Lord in thyself. The rememberers are three men: One remembers with the tongue while the heart is unaware. Another remembers with both tongue and heart, but his work is in danger, as has been said, " The self-purifiers are in grave danger. " Still another is silent with the tongue but his heart is drowned in Him. The Pir of the Tariqah said, " O God, how can I remember, for I myself am all remembrance? I have given the harvest of my marks to the wind. How can I remember Him whom I have not for- gotten? O remembrance of the spirits, remembered by the hearts, and mentioned by the tongues! Remember me with Your bounty and make me happy with gentle remembrance! "

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ، عَنْ عَبْدِ اللَّهِ ابْنِ بُحَيْنَةَ ـ رضى الله عنه ـ أَنَّهُ قَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَامَ مِنِ اثْنَتَيْنِ مِنَ الظُّهْرِ لَمْ يَجْلِسْ بَيْنَهُمَا، فَلَمَّا قَضَى صَلاَتَهُ سَجَدَ سَجْدَتَيْنِ ثُمَّ سَلَّمَ بَعْدَ ذَلِكَ‏.‏

Narrated `Abdullah bin Buhaina:Allah's Messenger (ﷺ) got up after the second rak`a of the Zuhr prayer without sitting in between (the second and the third rak`at). When he finished the prayer he performed two prostrations (of Sahu) and then finished the prayer with Taslim

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الظُّهْرَ خَمْسًا فَقِيلَ لَهُ أَزِيدَ فِي الصَّلاَةِ فَقَالَ ‏ "‏ وَمَا ذَاكَ ‏"‏‏.‏ قَالَ صَلَّيْتَ خَمْسًا‏.‏ فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ‏.‏

Narrated' `Abdullah:Once Allah's Messenger (ﷺ) offered five rak`at in the Zuhr prayer, and somebody asked him whether there was some increase in the prayer. Allah's Messenger (ﷺ) said, "What is that?" He said, "You have offered five rak`at." So Allah's Messenger (ﷺ) performed two prostrations of Sahu after Taslim

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، قَالَ أَنْبَأَنَا ابْنُ جُرَيْجٍ، عَنِ ابْنِ أَبِي عَمَّارٍ، عَنْ عَبْدِ اللَّهِ بْنِ بَابَيْهِ، عَنْ يَعْلَى بْنِ أُمَيَّةَ، قَالَ قُلْتُ لِعُمَرَ بْنِ الْخَطَّابِ ‏{‏ لَيْسَ عَلَيْكُمْ جُنَاحٌ أَنْ تَقْصُرُوا، مِنَ الصَّلاَةِ إِنْ خِفْتُمْ أَنْ يَفْتِنَكُمُ الَّذِينَ كَفَرُوا ‏}‏ فَقَدْ أَمِنَ النَّاسُ ‏.‏ فَقَالَ عُمَرُ رضى الله عنه عَجِبْتُ مِمَّا عَجِبْتَ مِنْهُ فَسَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ ذَلِكَ فَقَالَ ‏"‏ صَدَقَةٌ تَصَدَّقَ اللَّهُ بِهَا عَلَيْكُمْ فَاقْبَلُوا صَدَقَتَهُ ‏"‏ ‏.‏

It was narrated that Ya'la bin Umayyah said:"I said to 'Umar bin Al-Khattab: 'There is no sin on you if you shorten salah and if you fear that the disbelievers may put you in trial (attack you). But now the people are safe.' 'Umar said: 'I wondered the same thing, so I asked the Messenger of Allah (ﷺ) about that and he said: This is a favor from Allah (SWT) to you, so accept His favor

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أُمَيَّةَ بْنِ عَبْدِ اللَّهِ بْنِ خَالِدٍ، أَنَّهُ قَالَ لِعَبْدِ اللَّهِ بْنِ عُمَرَ إِنَّا نَجِدُ صَلاَةَ الْحَضَرِ وَصَلاَةَ الْخَوْفِ فِي الْقُرْآنِ وَلاَ نَجِدُ صَلاَةَ السَّفَرِ فِي الْقُرْآنِ ‏.‏ فَقَالَ لَهُ ابْنُ عُمَرَ يَا ابْنَ أَخِي إِنَّ اللَّهَ عَزَّ وَجَلَّ بَعَثَ إِلَيْنَا مُحَمَّدًا صلى الله عليه وسلم وَلاَ نَعْلَمُ شَيْئًا وَإِنَّمَا نَفْعَلُ كَمَا رَأَيْنَا مُحَمَّدًا صلى الله عليه وسلم يَفْعَلُ ‏.‏

It was narrated from Umayyah bin 'Abdullah bin Khalid that:He said to 'Abdullah bin 'Umar: "We find (mention of) prayer when one is at home (i.e., not traveling) and prayer at times of fear in the Qur'an, but we do not find any mention in the Qur'an of prayer when traveling. Ibn Umar said to him: 'O son of my brother, Allah (SWT) send Muhammad (ﷺ) to us when we did not know anything, and all we should do is to do that which we saw Muhammad (ﷺ) doing

حَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا ابْنُ فُضَيْلٍ، حَدَّثَنَا الأَعْمَشُ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ كُنَّا نُسَلِّمُ عَلَى النَّبِيِّ صلى الله عليه وسلم وَهُوَ فِي الصَّلاَةِ فَيَرُدُّ عَلَيْنَا، فَلَمَّا رَجَعْنَا مِنْ عِنْدِ النَّجَاشِيِّ سَلَّمْنَا عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْنَا وَقَالَ ‏ "‏ إِنَّ فِي الصَّلاَةِ شُغْلاً ‏"‏‏.‏

Narrated `Abdullah:We used to greet the Prophet (ﷺ) while he was praying and he used to answer our greetings. When we returned from An-Najashi (the ruler of Ethiopia), we greeted him, but he did not answer us (during the prayer) and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious matter)

Narrated `Abdullah:The same as No. 290. from the Prophet

فدلت هذه الحكايات والأخبار مع ما سبق على أن الأصل في الصلاة الخشوع وحضور القلب وأن مجرد الحركات مع الغفلة قليل الجدوى في المعاد والله أعلم

والحضور مضاد للعزوب والغفلة وإن لم يكن مفصلا

وأما ذكر الرعاية : فمثل قول الذاكر : الله معي والله ناظر إلي الله شاهدي ونحو ذلك مما يستعمل لتقوية الحضور مع الله وفيه رعاية لمصلحة القلب ولحفظ الأدب مع الله والتحرز من الغفلة والاعتصام من الشيطان والنفس

يريد بالخفي ههنا : الذكر بمجرد القلب بما يعرض له من الواردات وهذا ثمرة الذكر الأول ويريد بالخلاض من القيود : التخلص من الغفلة والنسيان والحجب الحائلة بين القلب وبين الرب سبحانه والبقاء مع الشهود : ملازمة الحضور مع المذكور ومشاهدة القلب له حتى كأنه يراه

ثم يتشعب من كل واحدة من هذه الخصال العشر عشر أخرى من الرذائل لم نطول بذكرها وتفصيل آحادها مثل الأنفة والغضب والبغضاء والطمع وحب طلب المال والجاه للتمكن من الغلبة والمباهاة والأشر والبطر وتعظيم الأغنياء والسلاطين والتردد إليهم والأخذ من حرامهم والتجمل بالخيول والمراكب والثياب المحظورة والاستحقار للناس بالفخر والخيلاء والخوض فيما لا يعني وكثرة الكلام وخروج الخشية والخوف والرحمة من القلب واستيلاء الغفلة عليه حتى لا يدري المصلي منهم في صلاته ما صلى وما الذي يقرأ ومن الذي يناجيه ولايحس بالخشوع من قلبه مع استغراق العمر في العلوم التي تعين في المناظرة مع أنها لا تنفع في الآخرة من تحسين العبارة وتسجيع اللفظ وحفظ النوادر إلى غير ذلك من أمور لا تحصى

وإذا أردت منهم هذا القدر كما ينبغي فانظر وقت أخذك في القراءة إذا أعرضت عن واجبها وتدبرها وتعقلها وفهم ما أريد بكل آية وحظك من الخطاب بها وتنزيلها على أدواء قلبك والتقيد بها كيف تدرك الختمة أو أكثرها أو ما قرأت منها بسهولة وخفة مستكثرا من القراءة فإذا ألزمت نفسك التدبر ومعرفة المراد والنظر إلى ما يخصك منه والتعبد به وتنزيل دوائه على أدواء قلبك والإستشفاء به لم تكد تجوز السورة أو الآية إلى غيرها وكذلك إذا جمعت قلبك كله على ركعتين أعطيتهما ما تقدر عليه من الحضور والخشوع والمراقبة لم تكد أن تصلي غيرهما إلا بجهد فإذا خلا القلب من ذلك عددت الركعات بلا حساب فالإستكثار من الطاعات دون مراعاة آفاتها وعيوبها ليتوب منها هي توبة العامة

Effects of L-theanine-caffeine combination on sustained attention and inhibitory control among children with ADHD: a proof-of-concept neuroimaging RCT.: We examined the acute effects of L-theanine, caffeine and their combination on sustained attention, inhibitory control and overall cognition in boys with attention deficit hyperactivity disorder (ADHD). L-Theanine (2.5 mg/kg), caffeine (2.0 mg/kg), their combination and a placebo were administered in a randomized four-way repeated-measures crossover with washout, to five boys (8-15 years) with ADHD. Functional magnetic resonance imaging (fMRI) was performed during a Go/NoGo task and a Stop-signa

Stimulating meditation: a pre-registered randomised controlled experiment combining a single dose of the cognitive enhancer, modafinil, with brief mindfulness training.: Background: Mindfulness-meditation has a variety of benefits on well-being. However, individuals with primary attentional impairments (e.g. attention deficit disorder) or attentional symptoms secondary to anxiety, depression or addiction, may be less likely to benefit, and require additional mindfulness-augmenting strategies. Aims: To determine whether a single dose of the cognitive enhancer, modafinil, acutely increases subjective and behavioural indices of mindfulness, and augments brief mindf

Mind Wandering (Internal Distractibility) in ADHD: A Literature Review.: Objective: Mind wandering, the unintended shifting of attention from a task, has been previously associated with symptoms of ADHD. To this end, we conducted a literature search to investigate the association between mind wandering and ADHD. Method: We conducted a systematic search of the literature of relevant articles assessing mind wandering and ADHD in PubMed, PsycINFO/OVID, and Medline. Included were original articles in English that had operationalized definitions of ADHD and mind wandering

A novel digital intervention for actively reducing severity of paediatric ADHD (STARS-ADHD): a randomised controlled trial.: Background: Attention-deficit hyperactivity disorder (ADHD) is a common paediatric neurodevelopmental disorder with substantial effect on families and society. Alternatives to traditional care, including novel digital therapeutics, have shown promise to remediate cognitive deficits associated with this disorder and may address barriers to standard therapies, such as pharmacological interventions and behavioural therapy. AKL-T01 is an investigational digital therapeutic designed to target attenti

Randomised sham-controlled study of high-frequency bilateral deep transcranial magnetic stimulation (dTMS) to treat adult attention hyperactive disorder (ADHD): Negative results.: Objectives: Recent studies support the possible effectiveness of repetitive transcranial magnetic stimulation (rTMS) as a treatment for attention deficit hyperactivity disorder (ADHD). The objective of this study was to evaluate the safety and possible efficacy of bilateral prefrontal deep rTMS for the treatment of adult ADHD. Methods: Twenty-six adult ADHD patients were randomised blindly to sham or actual deep TMS (dTMS). Twenty daily sessions were conducted using the bilateral H5 dTMS coil (B

Atomoxetine treatment of attention-deficit/hyperactivity disorder in young adults with assessment of functional outcomes: a randomized, double-blind, placebo-controlled clinical trial.: Background: Attention-deficit/hyperactivity disorder (ADHD) is associated with significant impairment in multiple functional domains. This trial evaluated efficacy in ADHD symptoms and functional outcomes in young adults treated with atomoxetine. Methods: Young adults (18-30 years old) with ADHD were randomized to 12 weeks of double-blind treatment with atomoxetine (n = 220) or placebo (n = 225). The primary efficacy measure of ADHD symptom change was Conners' Adult ADHD Rating Scale (CAARS): In

The risk of eating disorders comorbid with attention-deficit/hyperactivity disorder: A systematic review and meta-analysis.

Objective: There has been interest in whether people with Attention-Deficit/Hyperactivity Disorder (ADHD) are at higher risk of developing an Eating Disorder (ED). The aim of this study was estimate the size of this association with a meta-analysis of studies. Methods: We retrieved studies following PRISMA guidelines from a broad range of databases. Results: Twelve studies fitted our primary aim in investigating ED in ADHD populations (ADHD = 4,013/Controls = 29,404), and five exploring ADHD in ED populations (ED = 1,044/Controls = 11,292). The pooled odds ratio of diagnosing any ED in ADHD was increased significantly, 3.82 (95% CI:2.34-6.24). A similar level of risk was found across all ED syndromes [Anorexia Nervosa = 4.28 (95% CI:2.24-8.16); Bulimia Nervosa = 5.71 (95% CI: 3.56-9.16) and Binge Eating Disorder = 4.13 (95% CI:3-5.67)]. The risk was significantly higher if ADHD was diagn…

A Systematic Review and Meta-analysis of Neuroimaging in Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) Taking Attention-Deficit Hyperactivity Disorder (ADHD) Into Account.

Oppositional defiant disorder (ODD) and conduct disorder (CD) are common behavioural disorders in childhood and adolescence and are associated with brain abnormalities. This systematic review and meta-analysis investigates structural (sMRI) and functional MRI (fMRI) findings in individuals with ODD/CD with and without attention-deficit hyperactivity disorder (ADHD). Online databases were searched for controlled studies, resulting in 12 sMRI and 17 fMRI studies. In line with current models on ODD/CD, studies were classified in hot and cool executive functioning (EF). Both the meta-analytic and narrative reviews showed evidence of smaller brain structures and lower brain activity in individuals with ODD/CD in mainly hot EF-related areas: bilateral amygdala, bilateral insula, right striatum, left medial/superior frontal gyrus, and left precuneus. Evidence was present in both structural and …

Neural correlates of heart-focused interoception: a functional magnetic resonance imaging meta-analysis.

Interoception is the ability to perceive one's internal body state including visceral sensations. Heart-focused interoception has received particular attention, in part due to a readily available task for behavioural assessment, but also due to accumulating evidence for a significant role in emotional experience, decision-making and clinical disorders such as anxiety and depression. Improved understanding of the underlying neural correlates is important to promote development of anatomical-functional models and suitable intervention strategies. In the present meta-analysis, nine studies reporting neural activity associated with interoceptive attentiveness (i.e. focused attention to a particular interoceptive signal for a given time interval) to one's heartbeat were submitted to a multilevel kernel density analysis. The findings corroborated an extended network associated with heart-focus…

Neural, electrophysiological and anatomical basis of brain-network variability and its characteristic changes in mental disorders.

SEE MATTAR ET AL DOI101093/AWW151 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Functional brain networks demonstrate significant temporal variability and dynamic reconfiguration even in the resting state. Currently, most studies investigate temporal variability of brain networks at the scale of single (micro) or whole-brain (macro) connectivity. However, the mechanism underlying time-varying properties remains unclear, as the coupling between brain network variability and neural activity is not readily apparent when analysed at either micro or macroscales. We propose an intermediate (meso) scale analysis and characterize temporal variability of the functional architecture associated with a particular region. This yields a topography of variability that reflects the whole-brain and, most importantly, creates an analytical framework to establish the fundamental relationship between variabi…

Improving fluid intelligence with training on working memory: a meta-analysis.

Working memory (WM), the ability to store and manipulate information for short periods of time, is an important predictor of scholastic aptitude and a critical bottleneck underlying higher-order cognitive processes, including controlled attention and reasoning. Recent interventions targeting WM have suggested plasticity of the WM system by demonstrating improvements in both trained and untrained WM tasks. However, evidence on transfer of improved WM into more general cognitive domains such as fluid intelligence (Gf) has been more equivocal. Therefore, we conducted a meta-analysis focusing on one specific training program, n-back. We searched PubMed and Google Scholar for all n-back training studies with Gf outcome measures, a control group, and healthy participants between 18 and 50 years of age. In total, we included 20 studies in our analyses that met our criteria and found a small but…

The propagation of self-control: Self-control in one domain simultaneously improves self-control in other domains.

[Correction Notice: An Erratum for this article was reported in Vol 144(3) of Journal of Experimental Psychology: General (see record 2015-24174-008). The affiliations for co-authors Kuangjie Zhang and Steven Sweldens were incorrect. All versions of this article have been corrected.] A rich tradition in self-control research has documented the negative consequences of exerting self-control in 1 task for self-control performance in subsequent tasks. However, there is a dearth of research examining what happens when people exert self-control in multiple domains simultaneously. The current research aims to fill this gap. We integrate predictions from the most prominent models of self-control with recent neuropsychological insights in the human inhibition system to generate the novel hypothesis that exerting effortful self-control in 1 task can simultaneously improve self-control in complete…

Cognitive training for attention-deficit/hyperactivity disorder: meta-analysis of clinical and neuropsychological outcomes from randomized controlled trials.

Objective: The authors performed meta-analyses of randomized controlled trials to examine the effects of cognitive training on attention-deficit/hyperactivity disorder (ADHD) symptoms, neuropsychological deficits, and academic skills in children/adolescents with ADHD. Method: The authors searched Pubmed, Ovid, Web of Science, ERIC, and CINAHAL databases through May 18, 2014. Data were aggregated using random-effects models. Studies were evaluated with the Cochrane risk of bias tool. Results: Sixteen of 695 nonduplicate records were analyzed (759 children with ADHD). When all types of training were considered together, there were significant effects on total ADHD (standardized mean difference [SMD] = 0.37, 95% CI = 0.09-0.66) and inattentive symptoms (SMD = 0.47, 95% CI = 0.14-0.80) for reports by raters most proximal to the treatment setting (i.e., typically unblinded). These figures dec…

Attention bias modification for social anxiety: A systematic review and meta-analysis.

Research on attention bias modification (ABM) for social anxiety disorder (SAD) is inconclusive, with some studies finding clear positive effects and other studies finding no significant benefit relative to control training procedures. In this meta-analysis, we assessed the efficacy of ABM for SAD on symptoms, reactivity to speech challenge, attentional bias (AB) toward threat, and secondary symptoms at posttraining as well as SAD symptoms at 4-month follow-up. A systematic search in bibliographical databases uncovered 15 randomized studies involving 1043 individuals that compared ABM to a control training procedure. Data were extracted independently by two raters. The Q statistic was used to assess homogeneity across trials. All analyses were conducted on intent-to-treat data. ABM produced a small but significant reduction in SAD symptoms (g=0.27), reactivity to speech challenge (g=0.46…

The Meditative Mind: A Comprehensive Meta-Analysis of MRI Studies.

Over the past decade mind and body practices, such as yoga and meditation, have raised interest in different scientific fields; in particular, the physiological mechanisms underlying the beneficial effects observed in meditators have been investigated. Neuroimaging studies have studied the effects of meditation on brain structure and function and findings have helped clarify the biological underpinnings of the positive effects of meditation practice and the possible integration of this technique in standard therapy. The large amount of data collected thus far allows drawing some conclusions about the neural effects of meditation practice. In the present study we used activation likelihood estimation (ALE) analysis to make a coordinate-based meta-analysis of neuroimaging data on the effects of meditation on brain structure and function. Results indicate that meditation leads to activation…

Identifying a consistent pattern of neural function in attention deficit hyperactivity disorder: a meta-analysis.

Background: The neurobiological underpinnings of attention deficit hyperactivity disorder (ADHD) are inconclusive. Activation abnormalities across brain regions in ADHD compared with healthy controls highlighted in task-based functional magnetic resonance imaging (fMRI) studies are heterogeneous. To identify a consistent pattern of neural dysfunction in ADHD, a meta-analysis of fMRI studies using Go/no-go, Stop and N-back tasks was undertaken. Method: Several databases were searched using the key words: 'ADHD and fMRI' and 'ADHD and fMRI task'. In all, 20 studies met inclusion criteria comprising 334 patients with ADHD and 372 healthy controls and were split into N-back, Stop task and Go/no-go case-control groups. Using Signed Differential Mapping each batch was meta-analysed individually and meta-regression analyses were used to examine the effects of exposure to methylphenidate (MPH), …

Effects of stimulants on brain function in attention-deficit/hyperactivity disorder: a systematic review and meta-analysis.

Background: Psychostimulant medication, most commonly the catecholamine agonist methylphenidate, is the most effective treatment for attention-deficit/hyperactivity disorder (ADHD). However, relatively little is known on the mechanisms of action. Acute effects on brain function can elucidate underlying neurocognitive effects. We tested methylphenidate effects relative to placebo in functional magnetic resonance imaging (fMRI) during three disorder-relevant tasks in medication-naïve ADHD adolescents. In addition, we conducted a systematic review and meta-analysis of the fMRI findings of acute stimulant effects on ADHD brain function. Methods: The fMRI study compared 20 adolescents with ADHD under either placebo or methylphenidate in a randomized controlled trial while performing stop, working memory, and time discrimination tasks. The meta-analysis was conducted searching PubMed, ScienceD…

A meta-analysis of behavior therapy for Tourette Syndrome.

Individual randomized controlled trials (RCTs) of habit reversal training and a Comprehensive Behavioral Intervention for Tics (collectively referred to as behavior therapy, BT) have demonstrated efficacy in reducing tic severity for individuals with Tourette Syndrome and Chronic Tic Disorders (collectively referred to as TS), with no examination of treatment moderators. The present meta-analysis synthesized the treatment effect sizes (ES) of BT relative to comparison conditions, and examined moderators of treatment. A comprehensive literature search identified eight RCTs that met inclusion criteria, and produced a total sample of 438 participants. A random effects meta-analysis found a medium to large ES for BT relative to comparison conditions. Participant mean age, average number of therapy sessions, and the percentage of participants with co-occurring attention deficit hyperactivity …

Emotional and behavioural outcomes later in childhood and adolescence for children with specific language impairments: meta-analyses of controlled prospective studies.

Background: Prospective evidence on psychological outcomes for children with specific language impairments (SLI) is accumulating. To date, there has been no attempt to summarise what this evidence says about the strength of link between SLI and later child and adolescent emotional and behavioural (EB) outcomes. Methods: We undertook a systematic review and meta-analysis (following PRISMA guidelines and involving a literature search to June 2012 of seven databases, including MEDLINE and PsychAPA) of prospective, cohort studies of children with SLI and typical language development (TLD) reporting on the incidence and severity of EB problems later in childhood or adolescence. Results: Nineteen follow-up reports of eight cohorts with 553 SLI children and 1533 TLD controls were identified. Initial assessment was at 3-8.8 years of age and follow-up duration from 2 to 12 years. Pooled across co…

Meta-analysis of increased heart rate and blood pressure associated with CNS stimulant treatment of ADHD in adults.

Compared to children, adults with ADHD are at greater risk for developing adverse cardiovascular related outcomes and, if treated, may be likely to carry a greater burden of exposure to stimulant medications. The goal of this report is to critically review the available literature relevant to the cardiovascular safety of CNS stimulants for adult ADHD (aADHD). Twenty potential clinical trials of a CNS stimulant for aADHD have been published between 1979 and 2012. Of these, ten presented sufficient data to estimate the relative change in various cardiovascular parameters associated with ADHD treatment modalities. These trials were predominantly focused on long-acting stimulant preparations for acute symptom reduction (median duration=6 weeks, range: 4-24 weeks) and enrolled relatively young subjects (median age=36 years, range: 22-40). Using random effects meta-analysis, we found that subj…

Is working memory training effective? A meta-analytic review.

It has been suggested that working memory training programs are effective both as treatments for attention-deficit/hyperactivity disorder (ADHD) and other cognitive disorders in children and as a tool to improve cognitive ability and scholastic attainment in typically developing children and adults. However, effects across studies appear to be variable, and a systematic meta-analytic review was undertaken. To be included in the review, studies had to be randomized controlled trials or quasi-experiments without randomization, have a treatment, and have either a treated group or an untreated control group. Twenty-three studies with 30 group comparisons met the criteria for inclusion. The studies included involved clinical samples and samples of typically developing children and adults. Meta-analyses indicated that the programs produced reliable short-term improvements in working memory ski…

Attentional bias towards pain-related information in chronic pain; a meta-analysis of visual-probe investigations.

Research investigating the presence of attentional bias in chronic pain has produced mixed results. The purpose of this review is to summarise former research using the visual-probe task to explore attentional bias in pain populations, and meta-analyse the results of controlled investigations comparing individuals with chronic pain to healthy controls. Ten eligible studies were included in this analysis (chronic pain n=515, control n=314). Overall, individuals with chronic pain were found to show significantly greater bias towards pain-related information compared to controls, with an effect size of .36 (Hedges' adjusted g). The time-course of attentional bias was also explored, with evidence found for significant bias during stages of initial orienting of attention (effect size .29) and maintained attention (effect size .42). Bias therefore appears more pronounced during later stages of…

Aerobic exercise and neurocognitive performance: a meta-analytic review of randomized controlled trials.

Objectives: To assess the effects of aerobic exercise training on neurocognitive performance. Although the effects of exercise on neurocognition have been the subject of several previous reviews and meta-analyses, they have been hampered by methodological shortcomings and are now outdated as a result of the recent publication of several large-scale, randomized, controlled trials (RCTs). Methods: We conducted a systematic literature review of RCTs examining the association between aerobic exercise training on neurocognitive performance between January 1966 and July 2009. Suitable studies were selected for inclusion according to the following criteria: randomized treatment allocation; mean age > or =18 years of age; duration of treatment >1 month; incorporated aerobic exercise components; supervised exercise training; the presence of a nonaerobic-exercise control group; and sufficient info…

Comparing the efficacy of stimulants for ADHD in children and adolescents using meta-analysis.

Stimulants used to treat attention-deficit/hyperactivity disorder (ADHD) have been well researched, but comparisons among stimulants are hindered by the absence of direct comparative trials. The goal of this work was to compare the efficacy of methylphenidate and amfetamine formulations through a meta-analysis of double-blind placebo-controlled trials. We analyzed recent published literature on the stimulant therapy of ADHD to describe the variability of drug-placebo effect sizes. A literature search was conducted to identify double-blind, placebo-controlled studies of ADHD in children and adolescents published after 1979. Meta-analysis regression assessed the influence of medication type and study design features on medication effects. Twenty-three trials met criteria and were included in this meta-analysis. These trials studied 11 drugs using 19 different outcome measures of hyperactiv…

A meta-analysis of the impact of short-term sleep deprivation on cognitive variables.

A substantial amount of research has been conducted in an effort to understand the impact of short-term (<48 hr) total sleep deprivation (SD) on outcomes in various cognitive domains. Despite this wealth of information, there has been disagreement on how these data should be interpreted, arising in part because the relative magnitude of effect sizes in these domains is not known. To address this question, we conducted a meta-analysis to discover the effects of short-term SD on both speed and accuracy measures in 6 cognitive categories: simple attention, complex attention, working memory, processing speed, short-term memory, and reasoning. Seventy articles containing 147 cognitive tests were found that met inclusion criteria for this study. Effect sizes ranged from small and nonsignificant (reasoning accuracy: g = -0.125, 95% CI [-0.27, 0.02]) to large (lapses in simple attention: g = -0.…

Cognitive appraisals and emotions predict cortisol and immune responses: a meta-analysis of acute laboratory social stressors and emotion inductions.

Models of stress and health suggest that emotions mediate the effects of stress on health; yet meta-analytic reviews have not confirmed these relationships. Categorizations of emotions along broad dimensions such as valence (e.g., positive and negative affect) may obscure important information about the effects of specific emotions on physiology. Within the context of the integrated specificity model, we present a novel theoretical framework that posits that specific emotional responses associated with specific types of environmental demands influence cortisol and immune outcomes in a manner that would have likely promoted the survival of our ancestors. We analyzed experiments from 66 journal articles that directly manipulated social stress or emotions and measured subsequent cortisol or immune responses. Judges rated experiments for the extent to which participants would experience theo…

Delay and inhibition as early predictors of ADHD symptoms in third grade.

We used data from a large, longitudinal study of children in the community, the NICHD Study of Early Child Care and Youth Development, to examine how well earlier measures of delay capacity, inhibitory control, planning, and attention predicted symptoms of attention deficit hyperactivity disorder (ADHD) assessed in third grade. Children with elevated symptoms of both inattention and hyperactivity-impulsivity (n = 57) and with inattentive symptoms only (n = 80) were identified via mother and teacher reports using the "or" rule, as were children without significant symptoms (n = 790). Multinomial logistic regression analyses indicated that poorer performance on earlier measures of resistance to temptation, delay of gratification, response inhibition, attention, and planning obtained from 36 months to 1st grade predicted membership in the two symptom groups relative to the comparison group …

Comparative benefits and harms of competing medications for adults with attention-deficit hyperactivity disorder: a systematic review and indirect comparison meta-analysis.

Rationale: Recommended medication prescribing hierarchies for adult attention-deficit hyperactivity disorder (ADHD) vary between different guideline committees. Few trials directly compare competing ADHD medications in adults and provide little insight for clinicians making treatment choices. Objective: The objective of this study was to assess comparative benefits and harms of competing medications for adult ADHD using indirect comparison meta-analysis. Materials and methods: Eligible studies were English-language publications of randomized controlled trials comparing ADHD drugs to placebo. Data sources were electronic bibliographic databases, Drugs@FDA, manufacturer data, and reference lists. Two reviewers independently abstracted data on design, internal validity, population, and results. Benefits and harms were compared between drug types using indirect comparison meta-regression (ra…

Unrecognized attention-deficit/hyperactivity disorder in adults presenting with other psychiatric disorders.

Many adults with a diagnosed psychiatric disorder also have attention-deficit/hyperactivity disorder (ADHD). In many cases, comorbid ADHD is unrecognized and/or undertreated. Differential diagnosis of adult ADHD can be challenging because ADHD symptoms may overlap with other psychiatric disorders and patients may lack insight into their ADHD-related symptoms. Current ADHD diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision may prevent appropriate diagnosis of many patients with significant ADHD symptoms. Adults may not be able to provide a history of onset of symptoms during childhood, and it may be difficult to confirm that ADHD symptoms are not better accounted for by other comorbid psychiatric conditions. Comorbid ADHD is most prevalent among patients with mood, anxiety, substance use, and impulse-control disorders. ADHD can n…

Developmental trajectories of DSM-IV symptoms of attention-deficit/hyperactivity disorder: genetic effects, family risk and associated psychopathology.

Background: DSM-IV specifies three ADHD subtypes; the combined, the hyperactive-impulsive and the inattentive. Little is known about the developmental relationships underlying these subtypes. The objective of this study was to describe the development of parent-reported hyperactivity-impulsivity and inattention symptoms from childhood to adolescence and to study their associations with genetic factors, family risk, and later adjustment problems in early adulthood. Method: Data in this study comes from 1,450 twin pairs participating in a population-based, longitudinal twin study. Developmental trajectories were defined using parent-ratings of hyperactivity-impulsivity and inattention symptoms at age 8-9, 13-14, and 16-17. Twin methods were used to explore genetic influences on trajectories. Family risk measures included low socioeconomic status, large family size and divorce. Self-ratings…
