يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱجۡتَنِبُواْ كَثِيرࣰ ا مِّنَ ٱلظَّنِّ إِنَّ بَعۡضَ ٱلظَّنِّ إِثۡمࣱۖ وَلَا تَجَسَّسُواْ وَلَا يَغۡتَب بَّعۡضُكُم بَعۡضًاۚ أَيُحِبُّ أَحَدُكُمۡ أَن يَأۡكُلَ لَحۡمَ أَخِيهِ مَيۡتࣰ ا فَكَرِهۡتُمُوهُۚ وَٱتَّقُواْ ٱللَّهَۚ إِنَّ ٱللَّهَ تَوَّابࣱ رَّحِيمࣱ‏

Believers, avoid making too many assumptions- some assumptions are sinful- and do not spy on one another or speak ill of people behind their backs: would any of you like to eat the flesh of your dead brother? No, you would hate it. So be mindful of God: God is ever relenting, most merciful

وَلَا جُنَاحَ عَلَيۡكُمۡ فِيمَا عَرَّضۡتُم بِهِۦ مِنۡ خِطۡبَةِ ٱلنِّسَآءِ أَوۡ أَكۡنَنتُمۡ فِيٓ أَنفُسِكُمۡۚ عَلِمَ ٱللَّهُ أَنَّكُمۡ سَتَذۡكُرُونَهُنَّ وَلَٰكِن لَّا تُوَاعِدُوهُنَّ سِرًّا إِلَّآ أَن تَقُولُواْ قَوۡلࣰ ا مَّعۡرُوفࣰ اۚ وَلَا تَعۡزِمُواْ عُقۡدَةَ ٱلنِّكَاحِ حَتَّىٰ يَبۡلُغَ ٱلۡكِتَٰبُ أَجَلَهُۥۚ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ يَعۡلَمُ مَا فِيٓ أَنفُسِكُمۡ فَٱحۡذَرُوهُۚ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ غَفُورٌ حَلِيمࣱ‏

You will not be blamed whether you give a hint that you wish to marry these women, or keep it to yourselves- God knows that you intend to propose to them. Do not make a secret arrangement with them; speak to them honourably and do not confirm the marriage tie until the prescribed period reaches its end. Remember that God knows what is in your souls, so be mindful of Him. Remember that God is most forgiving and forbearing

هَٰٓأَنتُمۡ أُوْلَآءِ تُحِبُّونَهُمۡ وَلَا يُحِبُّونَكُمۡ وَتُؤۡمِنُونَ بِٱلۡكِتَٰبِ كُلِّهِۦ وَإِذَا لَقُوكُمۡ قَالُوٓاْ ءَامَنَّا وَإِذَا خَلَوۡاْ عَضُّواْ عَلَيۡكُمُ ٱلۡأَنَامِلَ مِنَ ٱلۡغَيۡظِۚ قُلۡ مُوتُواْ بِغَيۡظِكُمۡۗ إِنَّ ٱللَّهَ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

This is how it is: here you are, you love them, but they do not love you; you believe in all the Scriptures and when they meet you, they say, ‘We believe,’ but when they are alone, they bite their fingertips in rage at you. [Prophet], say, ‘Die of rage [if you wish]!’ God knows exactly what is in everyone’s hearts

ثُمَّ أَنزَلَ عَلَيۡكُم مِّنۢ بَعۡدِ ٱلۡغَمِّ أَمَنَةࣰ نُّعَاسࣰ ا يَغۡشَىٰ طَآئِفَةࣰ مِّنكُمۡۖ وَطَآئِفَةࣱ قَدۡ أَهَمَّتۡهُمۡ أَنفُسُهُمۡ يَظُنُّونَ بِٱللَّهِ غَيۡرَ ٱلۡحَقِّ ظَنَّ ٱلۡجَٰهِلِيَّةِۖ يَقُولُونَ هَل لَّنَا مِنَ ٱلۡأَمۡرِ مِن شَيۡءࣲۗ قُلۡ إِنَّ ٱلۡأَمۡرَ كُلَّهُۥ لِلَّهِۗ يُخۡفُونَ فِيٓ أَنفُسِهِم مَّا لَا يُبۡدُونَ لَكَۖ يَقُولُونَ لَوۡ كَانَ لَنَا مِنَ ٱلۡأَمۡرِ شَيۡءࣱ مَّا قُتِلۡنَا هَٰهُنَاۗ قُل لَّوۡ كُنتُمۡ فِي بُيُوتِكُمۡ لَبَرَزَ ٱلَّذِينَ كُتِبَ عَلَيۡهِمُ ٱلۡقَتۡلُ إِلَىٰ مَضَاجِعِهِمۡۖ وَلِيَبۡتَلِيَ ٱللَّهُ مَا فِي صُدُورِكُمۡ وَلِيُمَحِّصَ مَا فِي قُلُوبِكُمۡۚ وَٱللَّهُ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

After sorrow, He caused calm to descend upon you, a sleep that overtook some of you. Another group, caring only for themselves, entertained false thoughts about God, thoughts more appropriate to pagan ignorance, and said, ‘Do we get a say in any of this?’ [Prophet], tell them, ‘Everything to do with this affair is in God’s hands.’ They conceal in their hearts things they will not reveal to you. They say, ‘If we had had our say in this, none of us would have been killed here.’ Tell them, ‘Even if you had resolved to stay at home, those who were destined to be killed would still have gone out to meet their deaths.’ God did this in order to test everything within you and in order to prove what is in your hearts. God knows your innermost thoughts very well

وَٱذۡكُرُواْ نِعۡمَةَ ٱللَّهِ عَلَيۡكُمۡ وَمِيثَٰقَهُ ٱلَّذِي وَاثَقَكُم بِهِۦٓ إِذۡ قُلۡتُمۡ سَمِعۡنَا وَأَطَعۡنَاۖ وَٱتَّقُواْ ٱللَّهَۚ إِنَّ ٱللَّهَ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

Remember God’s blessing on you and the pledge with which you were bound when you said, ‘We hear and we obey.’ Be mindful of God: God has full knowledge of the secrets of the heart

إِذۡ يُرِيكَهُمُ ٱللَّهُ فِي مَنَامِكَ قَلِيلࣰ اۖ وَلَوۡ أَرَىٰكَهُمۡ كَثِيرࣰ ا لَّفَشِلۡتُمۡ وَلَتَنَٰزَعۡتُمۡ فِي ٱلۡأَمۡرِ وَلَٰكِنَّ ٱللَّهَ سَلَّمَۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

[Prophet], remember when God made you see them in your sleep as few: if He had shown them to you [believers] as many, you would certainly have lost heart and argued about it, but God saved you. He knows the secrets of the heart

O you who believe shun much suspicion. Indeed some suspicions are sins that is to say it causes one to fall into sin. This suspicion may have many forms such as thinking ill of the good folk from among the believers — and such good folk are many — in contrast to the immoral individuals among them in whose case there is no sin so long as it the suspicion is in accordance with their outward behaviour. And do not spy tajassasū one of the two tā’ letters of tatajassasū has been omitted do not pursue the imperfections and faults of Muslims by searching them out; nor backbite one another do not speak of him by mentioning something which he is averse to having mentioned of himself even if it be true. Would any of you love to eat the flesh of his brother dead? read maytan or mayyitan. That is to say it would not be right for him to do so. You would abhor it. Thus to backbite him in life would be

O you who believe! Avoid much suspicion; indeed some suspicion is sin. And spy not, neither backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it. And have Taqwa of Allah. Verily, Allah is the One Who forgives and accepts repentance, Most Merciful (12) The Prohibition of Unfounded Suspicion Allah the Exalted forbids His faithful servants from being suspicious, which includes having doubts and suspicions about the conduct of one's family, relatives and other people in general. Therefore, Muslims are to avoid suspicion without foundation. The Leader of the faithful 'Umar bin Al-Khattab said, "Never think ill of the word that comes out of your believing brother's mouth, as long as you can find a good excuse for it." Malik recorded that Abu Hurayrah, may Allah be pleased with him, said that Allah's Messenger ﷺ said, إِيَّاكُمْ وَالظَّنَّ فَإِ

Ha! There you are: You love them, but they do not love you. The faithful had limpid hearts and generous natures, and they did not keep tenderness and mercy back from the estranged. They wanted good for them and attached their hearts to their submission. They wanted their salvation and did not hold back God's mercy from them-whether they were acquaintances or strangers. This kept on crossing their minds: Bring the sweetmeat, for it is the heart's beloved, suited for both the elect and the common. This is the same tenderness that MuḤammad showed to the estranged. He said, “O God, guide my people, for they do not know.” As for the unbelievers, those who had no limpidness in their hearts or loyalty in their natures, they never wanted good for the people of faith, nor did they love them. They grieved at the good that reached them and became happy at the bad. God says, “If something beautiful

You would not be at fault regarding the proposal with the intention of marriage you present offer or hide in your hearts during the waiting period to women whose spouses have died such as men saying ‘How beautiful you are!’ or ‘Who could find one like you?’ or ‘How many a man must desire you!’. God knows that you will be mindful of them in proposing to them impatiently and so He has permitted you to make such offers; but do not make arrangements of marriage with them secretly unless you speak honourable words such as are acknowledged by the Law in other words such as proposals that which is permitted to you. And do not resolve on the knot the consummation of marriage until that which is written the period prescribed has reached its term and has been completed; and know that God knows what is in your souls of resolve or otherwise; so be fearful of Him that He should chastise you if you ha

And there is no sin on you if you make a hint of betrothal or conceal it in yourself, Allah knows that you will remember them, but do not make a promise (of contract) with them in secret except that you speak an honorable saying. And do not be determined on the marriage bond until the term prescribed is fulfilled. And know that Allah knows what is in your minds, so fear Him. And know that Allah is Oft-Forgiving, Most Forbearing (235) Mentioning Marriage indirectly during the 'Iddah Allah said: وَلَا جُنَاحَ عَلَيْكُمْ (And there is no sin on you) meaning, to indirectly mention marriage to the widow during the term of 'Iddah for her deceased husband. Ath-Thawri, Shu'bah and Jarir stated that Ibn 'Abbas said: وَلَا جُنَاحَ عَلَيْكُمْ فِيمَا عَرَّضْتُم بِهِ مِنْ خِطْبَةِ النِّسَاءِ (And there is no sin on you if you make a hint of betrothal) "means saying, 'I want to marry and I am lo

Lo hā ‘lo!’ is for calling attention to something there you are O believers you love them on account of their kinship and their pretence of friendship towards you but they love you not since they oppose you in religion; you believe in the Book all of it that is to say in the Books all of them but they do not believe in your Book and when they meet you they say ‘We believe’ but when they are alone they bite at you their fingertips in rage in extreme fury at what they see of your mutual affection the biting of the fingertips is used to figuratively express the severity of rage even if there be no biting involved. Say ‘Perish in your rage that is be this way until the end of your lives for you shall not see what will please you; God knows what is in the breasts’ what is in the hearts including that which these conceal.

Abu Talha reported:While we were sitting in front of the houses and talking amongst ourselves, Allah's Messenger (ﷺ) happened to come there. He stood by us and said: What about you and your meetings on the paths? Avoid these meetings on the paths. We said: We were sitting here without (any intention of doing harm to the passers-by) ; we are sitting to discuss matters and to hold conversation amongst ourselves. Thereupon he said: If there is no help (for you but to sit on these paths), then give the paths their rights and these are lowering of the gaze, exchanging of greetings and good conversation

Oxytocin improves behavioural and neural deficits in inferring others' social emotions in autism.: Recent studies have suggested oxytocin's therapeutic effects on deficits in social communication and interaction in autism spectrum disorder through improvement of emotion recognition with direct emotional cues, such as facial expression and voice prosody. Although difficulty in understanding of others' social emotions and beliefs under conditions without direct emotional cues also plays an important role in autism spectrum disorder, no study has examined the potential effect of oxytocin on this

MDMA enhances emotional empathy and prosocial behavior.: 3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') releases serotonin and norepinephrine. MDMA is reported to produce empathogenic and prosocial feelings. It is unknown whether MDMA in fact alters empathic concern and prosocial behavior. We investigated the acute effects of MDMA using the Multifaceted Empathy Test (MET), dynamic Face Emotion Recognition Task (FERT) and Social Value Orientation (SVO) test. We also assessed effects of MDMA on plasma levels of hormones involved in social behavior

An individual task meta-analysis of social cognition in euthymic bipolar disorders.: Objective: Social cognition has been shown to be affected in bipolar disorders, even during euthymia. However, the social cognitive profile of this group of disorders remains to be ascertained, given that such a broad neuropsychological construct has not been systematically examined in bipolar subjects across different tasks. The aim of this study was to quantify the magnitude of patient-control differences for distinct social cognition assessment instruments: the Hinting Task, the Eyes Test, Fa

Personality-dependent effects of oxytocin: greater social benefits for high alexithymia scorers.: Originally known for its role in labor and lactation, oxytocin (OT) has recently been shown to facilitate social behaviour by improving socio-emotional abilities. However, whether OT is equally beneficial to all people, or whether is it particularly beneficial to less emotionally/socially competent (i.e., high alexithymia) individuals it is not yet known. We investigated the effects of OT on individuals of varying socio-emotional ability by randomly assigning sixty male students to receive eithe

Empathy in adults with clinical or subclinical depressive symptoms.: Background: Depression is associated with problems in social functioning. Impaired empathic abilities might underlie this association. Empathy is a multidimensional construct and involves both affective and cognitive processes. We reviewed the literature to find out to what extent depression may be associated with abnormal levels of affective and cognitive empathy. We also explored potential gender differences in these associations. Methods: We used PsycInfo and Medline to conduct a systematic r

Preliminary evidence about the effects of meditation on interoceptive sensitivity and social cognition.: Background: Interoception refers to the conscious perception of body signals. Mindfulness is a meditation practice that encourages individuals to focus on their internal experiences such as bodily sensations, thoughts, and emotions. In this study, we selected a behavioral measure of interoceptive sensitivity (heartbeat detection task, HBD) to compare the effect of meditation practice on interoceptive sensitivity among long term practitioners (LTP), short term meditators (STM, subjects that compl

An oxytocin-dependent social interaction between larvae and adult C. elegans.

Oxytocin has a conserved role in regulating animal social behaviour including parental-offspring interactions. Recently an oxytocin-like neuropeptide, nematocin, and its cognate receptors have been identified in the nematode Caenorhabditis elegans. We provide evidence for a pheromone signal produced by C. elegans larvae that modifies the behaviour of adult animals in an oxytocin-dependent manner increasing their probability of leaving a food patch which the larvae are populating. This increase is positively correlated to the size of the larval population but cannot be explained by food depletion nor is it modulated by biogenic amines, which suggest it is not an aversive behaviour. Moreover, the food-leaving behaviour is conspecific and pheromone dependent: C. elegans adults respond more strongly to C. elegans larvae compared to other nematode species and this effect is absent in C. elega…

Effect of maternal renin-angiotensin-aldosterone system activation on social coping strategies and gene expression of oxytocin and vasopressin in the brain of rat offspring in adulthood.

The intrauterine condition in which the mammalian foetus develops has an important role in prenatal programming. The aim of this study was to determine the extent to which activation of the maternal renin-angiotensin-aldosterone system (RAAS) could influence social behaviour strategies in offspring via changes in social neurotransmitters in the brain. Pregnant female Wistar rats were implanted with osmotic minipumps which continually released angiotensin II for 14 days at concentration of 2 μg/kg/h. The adult offspring (angiotensin and control groups) underwent a social interaction test. The mRNA expression of vasopressin, oxytocin and the oxytocin receptor in selected brain areas was measured by in situ hybridisation. Prenatal exposure to higher levels of angiotensin II resulted in a strong trend toward decreased total social interaction time and significantly decreased time spent in cl…

Suppressed play behaviour and decreased oxytocin receptor binding in the amygdala after prenatal exposure to low-dose valproic acid.

To better understand the role of the neuropeptide oxytocin in autism spectrum disorder (ASD), we investigated potential deficits in social play behaviour and oxytocin receptor (OXTR) density alterations in the amygdala in a rodent model of ASD. Pregnant rats were injected daily with 20 or 100 mg/kg valproic acid (VPA) or saline from day 12 until the end of pregnancy. The number of pinning and pouncing events was assessed at postnatal days 29-34. Brains from male offspring (n=7/group) were removed at postnatal day 50. We performed quantitative autoradiography with an OXTR radioligand, the [I]-ornithine vasotocin analogue, in brain slices from the amygdala and other limbic brain regions involved in rat social behaviour. The results demonstrated a significant reduction in pinning behaviour and decreased OXTR density in the central nucleus of the amygdala in the 20 mg/kg VPA group. However, …

Oxytocin Acting in the Nucleus Accumbens Core Decreases Food Intake.

Central oxytocin (OT) promotes feeding termination in response to homeostatic challenges, such as excessive stomach distension, salt loading and toxicity. OT has also been proposed to affect feeding reward by decreasing the consumption of palatable carbohydrates and sweet tastants. Because the OT receptor (OTR) is expressed in the nucleus accumbens core (AcbC) and shell (AcbSh), a site regulating diverse aspects of eating behaviour, we investigated whether OT acts there to affect appetite in rats. First, we examined whether direct AcbC and AcbSh OT injections affect hunger- and palatability-driven consumption. We found that only AcbC OT infusions decrease deprivation-induced chow intake and reduce the consumption of palatable sucrose and saccharin solutions in nondeprived animals. These effects were abolished by pretreatment with an OTR antagonist, L-368,899, injected in the same site. A…

Autistic Traits Moderate the Impact of Reward Learning on Social Behaviour.

A deficit in empathy has been suggested to underlie social behavioural atypicalities in autism. A parallel theoretical account proposes that reduced social motivation (i.e., low responsivity to social rewards) can account for the said atypicalities. Recent evidence suggests that autistic traits modulate the link between reward and proxy metrics related to empathy. Using an evaluative conditioning paradigm to associate high and low rewards with faces, a previous study has shown that individuals high in autistic traits show reduced spontaneous facial mimicry of faces associated with high vs. low reward. This observation raises the possibility that autistic traits modulate the magnitude of evaluative conditioning. To test this, we investigated (a) if autistic traits could modulate the ability to implicitly associate a reward value to a social stimulus (reward learning/conditioning, using th…

The effect of oxytocin on biological motion perception in dogs (Canis familiaris).

Recent studies have shown that the neuropeptide oxytocin is involved in the regulation of several complex human social behaviours. There is, however, little research on the effect of oxytocin on basic mechanisms underlying human sociality, such as the perception of biological motion. In the present study, we investigated the effect of oxytocin on biological motion perception in dogs (Canis familiaris), a species adapted to the human social environment and thus widely used to model many aspects of human social behaviour. In a within-subjects design, dogs (N = 39), after having received either oxytocin or placebo treatment, were presented with 2D projection of a moving point-light human figure and the inverted and scrambled version of the same movie. Heart rate (HR) and heart rate variability (HRV) were measured as physiological responses, and behavioural response was evaluated by observin…

Sex-Dependent Effects of Prenatal Stress on Social Memory in Rats: A Role for Differential Expression of Central Vasopressin-1a Receptors.

Prenatal stress (PNS) affects a number of traits in the offspring, including stress axis regulation, emotionality and cognition; however, much less is known about the effects of PNS on social memory and the underlying central mechanisms. In the present study, we investigated social preference, social memory under basal and stress conditions and olfactory memory for social and nonsocial odours in the adult offspring of dams exposed to social stress during late pregnancy. Given the key roles that the central oxytocin and vasopressin systems play in facilitating social memory, we further investigated the effects of PNS on the central expression of mRNA for oxytocin (Oxtr) and vasopressin-1a (Avpr1a) receptors. PNS did not affect social preference in either sex; however, social memory was impaired under basal conditions in PNS females but not PNS males. Accordingly, Avpr1a mRNA expression in…

Intranasal oxytocin administration in relationship to social behaviour in domestic pigs.

Intranasal administration of oxytocin has been shown to alter positive and negative social behaviour. Positive social behaviour in pigs (Sus scrofa) may be expressed through gentle social nosing, and greater insight in the specific expression hereof might contribute to the current search for positive indicators of animal welfare. We investigated whether oxytocin alters social nosing and whether this is specific to nose-body or nose-nose contact. Sixty-four focal female pigs of 13weeks of age (out of 16 groups) were given oxytocin (24IU dose) and saline (placebo) intranasally once on two consecutive days. The frequency of nose-to-nose contact and nose-to-body contact was recorded upon pigs' return in the home pen after being for 10min located in a separate area near pen mates undergoing a positive or negative event or not. The effect of intranasal oxytocin depended on the social context i…

The Effect of Oxytocin on Social and Non-Social Behaviour and Striatal Protein Expression in C57BL/6N Mice.

Oxytocin has been suggested as a promising new treatment for neurodevelopmental disorders. However, important gaps remain in our understanding of its mode of action, in particular, to what extent oxytocin modulates social and non-social behaviours and whether its effects are generalizable across both sexes. Here we investigated the effects of a range of oxytocin doses on social and non-social behaviours in C57BL/6N mice of both sexes. As the striatum modulates social and non-social behaviours, and is implicated in neurodevelopmental disorders, we also conducted a pilot exploration of changes in striatal protein expression elicited by oxytocin. Oxytocin increased prepulse inhibition of startle but attenuated the recognition memory in male C57BL/6N mice. It increased social interaction time and suppressed the amphetamine locomotor response in both sexes. The striatum proteome following oxy…

Oxytocin in the regulation of social behaviours in medial amygdala-lesioned mice via the inhibition of the extracellular signal-regulated kinase signalling pathway.

The neuropeptide oxytocin (OXT) has been implicated in the pathophysiology of behavioural deficits among patients with autism spectrum disorder (ASD). However, the molecular mechanisms underlying its role in ASD remain unclear. In the present study, a murine model with ASD-like phenotypes was induced by intra-medial amygdala injection of N-methyl-d-aspartate, and it was used to investigate the role of OXT in behaviour regulation. Behavioural tests were performed to verify the ASD-like phenotypes of N-methyl-d-aspartate-treated mice, and the results showed that mice with bilateral medial amygdala lesions presented significant behavioural deficits, including impaired learning and memory and increased anxiety and depression. We also observed a notably decreased level of OXT in both the plasma and the hypothalamus of medial amygdala-lesioned mice, and the extracellular signal-regulated kinas…

Intranasally administered oxytocin affects how dogs (Canis familiaris) react to the threatening approach of their owner and an unfamiliar experimenter.

Fear and aggression are among the most prominent behavioural problems in dogs. Oxytocin has been shown to play a role in regulating social behaviours in humans including fear and aggression. As intranasal oxytocin has been found to have some analogous effects in dogs and humans, here we investigated the effect of oxytocin on dogs' behaviour in the Threatening Approach Test. Dogs, after having received intranasal administration of oxytocin (OT) or placebo (PL), showed the same reaction to an unfamiliar experimenter, but OT pretreated dogs showed a less friendly first reaction compared to the PL group when the owner was approaching. Individual differences in aggression (measured via questionnaire) also modulated dogs' first reaction. Moreover, subjects that received OT looked back more at the human (owner/experimenter) standing behind them during the threatening approach. These results sug…

Increased sociability and gene expression of oxytocin and its receptor in the brains of rats affected prenatally by valproic acid.

Autism is a neurodevelopmental disorder characterised by the disruption of social interactions. Autistic animal models play a crucial role in neurophysiologic research on this disorder. One of these models is based on rats that have been prenatally treated with valproic acid - VPA rats. The aim of our study performed with this model was to investigate changes in sociability and gene expression of neuropeptides and receptors involved in regulating social behaviour. We focused on gene expression in the hypothalamus, where the neuropeptides oxytocin (OT) and arginine-vasopressin (AVP) are produced, as well as oxytocin receptors (OTR) in certain neuronal structures involved in the creation of social abilities. Our research showed that VPA rats spent more time in the part with an unknown animal and less time in the central part of a three chamber sociability test apparatus than control animal…

Social feedback processing from early to late adolescence: influence of sex, age, and attachment style.

Objective: The establishment of an accurate understanding of one's social context is a central developmental task during adolescence. A critical component of such development is to learn how to integrate the objective evaluation of one's behavior with the social response to the latter--here referred to as social feedback processing. Case report: We measured brain activity by means of fMRI in 33 healthy adolescents (12-19 years old, 14 females). Participants played a difficult perceptual game with integrated verbal and visual feedback. Verbal feedback provided the participants with objective performance evaluation (won vs. lost). Visual feedback consisted of either smiling or angry faces, representing positive or negative social evaluations. Together, the combination of verbal and visual feedback gave rise to congruent versus incongruent social feedback combinations. In addition to assess…

Neuroendocrine and behavioural responses to exposure to an infant in male prairie voles.

Paternal behaviour and pair-bond formation are defining characteristics of social monogamy. However, in comparison to pair-bonding, the endocrine factors associated with the male care of young are not well studied. In the present study, plasma concentrations of oxytocin, vasopressin and corticosterone (CORT) were measured in reproductively naïve male prairie voles as a function of exposure to an infant or control manipulations (i.e. handling or exposure to a wooden dowel). Plasma oxytocin concentrations were transiently elevated within 10 min of pup exposure. Although plasma CORT concentration typically increases after handling, after 10 min of pup exposure, the concentration of plasma CORT was not increased, suggesting an attenuation of CORT release by pup exposure. Group differences in the concentrations of plasma hormones were no longer detected at 20 or 60 min after treatment. These …

Arginine vasotocin regulation of interspecific cooperative behaviour in a cleaner fish.

In an interspecific cooperative context, individuals must be prepared to tolerate close interactive proximity to other species but also need to be able to respond to relevant social stimuli in the most appropriate manner. The neuropeptides vasopressin and oxytocin and their non-mammalian homologues have been implicated in the evolution of sociality and in the regulation of social behaviour across vertebrates. However, little is known about the underlying physiological mechanisms of interspecific cooperative interactions. In interspecific cleaning mutualisms, interactions functionally resemble most intraspecific social interactions. Here we provide the first empirical evidence that arginine vasotocin (AVT), a non-mammalian homologue of arginine vasopressin (AVP), plays a critical role as moderator of interspecific behaviour in the best studied and ubiquitous marine cleaning mutualism invo…

Differential contribution of hypothalamic MAPK activity to anxiety-like behaviour in virgin and lactating rats.

The c-Raf - MEK1/2 - ERK1/2 mitogen-activated protein kinase (MAPK) intracellular signalling cascade in neurons plays important roles in the control of a variety of behaviours, including social behaviours and anxiety. These roles partially overlap with those described for oxytocin (OXT), and it has been shown that OXT activates the MAPK pathway in the hypothalamus (of male), and hippocampus (of female) rats. Here, by combining behavioural (light/dark box) and biochemical analyses (western blotting), we tested two hypotheses: (i) that OXT is anxiolytic within the hypothalamus of females, and (ii) that this effect, as well as that of lactation-associated anxiolysis, depends on the recruitment of the MAPK pathway. We found that, when injected bilaterally into the hypothalamic paraventricular nucleus (PVN), OXT decreased anxiety-like behaviour in virgins, and that this effect depended on pho…

Neural systems of threat processing in adolescents: role of pubertal maturation and relation to measures of negative affect.

Adolescence ushers in dramatic social and affective changes and increased vulnerability for affective disorders. Yet, little is known about the effects of pubertal maturation on neural systems of social threat processing. We examined adolescents' brain function to social stimuli in relation to pubertal maturation, depressive symptoms, and real-world subjective negative affect. Compared with pre/early adolescents, mid/late adolescents exhibited less amygdala reactivity to emotionally neutral faces relative to non-face stimuli; less ventrolateral prefrontal cortex (VLPFC) reactivity to fearful faces relative to non-face stimuli, neutral faces, or angry faces; and more VLPFC reactivity to angry relative to neutral faces. Amygdala and VLPFC reactivity were correlated with negative affect and depressive symptoms. Threat-processing changes during puberty may facilitate changes in social behavi…

Facial emotion recognition and its relationship to subjective and functional outcomes in remitted patients with bipolar I disorder.

Objectives: Outcome in bipolar disorder (BD) is multidimensional and consists of clinical and psychosocial domains. Difficulties in affect recognition and in emotional experience are a hallmark of BD, but there is little research investigating the consequences of this deficit on the psychosocial status of patients who are in remission. Methods: This cross-sectional study examined the relationship of facial affect recognition and treatment outcomes in terms of psychopathology, quality of life, and psychosocial functioning in remitted BD patients compared to healthy volunteers. Results: Altogether, 47 outpatients meeting diagnostic criteria for bipolar I disorder according to DSM-IV and 45 healthy control subjects were included in the study. Patients were particularly impaired in the recognition of facial expressions depicting disgust and happiness. For patients, the most frequently observ…

Maternal and paternal plasma, salivary, and urinary oxytocin and parent-infant synchrony: considering stress and affiliation components of human bonding.

Studies in mammals have implicated the neuropeptide oxytocin (OT) in processes of bond formation and stress modulation, yet the involvement of OT in human bonding throughout life remains poorly understood. We assessed OT in the plasma, saliva, and urine of 112 mothers and fathers interacting with their 4-6-month-old infants. Parent-infant interactions were micro-coded for parent and child's social behaviors and for the temporal coordination of their socio-affective cues. Parents were interviewed regarding their attachment to the infant and reported on bonding to own parents, romantic attachment, and parenting stress. Results indicated that OT in plasma (pOT) and saliva (sOT) were inter-related and were unrelated to OT in urine (uOT). pOT and sOT in mothers and fathers were associated with parent and child's social engagement, affect synchrony, and positive communicative sequences between…

Oxytocin mediates social neuroprotection after cerebral ischemia.

Background and purpose: The reduced incidence, morbidity, and mortality of stroke among humans with strong social support have been well-documented; however, the mechanisms underlying these socially mediated phenomena remain unknown, but may involve oxytocin (OT), a hormone that modulates some aspects of social behavior in humans and other animals. Methods: In the present study, adult male mice were socially isolated (housed individually) or socially paired (housed with an ovariectomized female); social pairing increased hypothalamic OT gene expression. To determine whether a causal relationship exists between increased OT and improved stroke outcome, mice were treated with exogenous OT or OT receptor antagonist beginning 1 week before induction of experimental stroke via middle cerebral artery occlusion. Results: Relative to social isolation, social housing attenuated infarct size, neur…

Residual social, memory and oxytocin-related changes in rats following repeated exposure to γ-hydroxybutyrate (GHB), 3,4-methylenedioxymethamphetamine (MDMA) or their combination.

Rationale: There has been little investigation of the possible lasting adverse effects of γ-hydroxybutyrate (GHB). Objectives: This study aims to study whether GHB produces residual adverse effects on memory and social behaviour in rats and lasting changes in brain monoamines and oxytocin-related gene expression. Methods: Rats received daily intraperitoneal injections of GHB (500 mg/kg), methylenedioxymethamphetamine (MDMA; 5 mg/kg) or their combination (GHB/MDMA) over ten consecutive days. Locomotor activity and body weight were assessed during the dosing period and withdrawal-related anxiety was assessed 24 h after drug cessation. After a washout of 4 weeks, rats were tested on the emergence, social interaction, and object recognition tasks over a 2-week period. Monoamine levels in cortex and striatum, and hypothalamic oxytocin and oxytocin receptor mRNA, were then assessed. Results: M…

Social vocalizations can release oxytocin in humans.

Vocalizations are important components of social behaviour in many vertebrate species, including our own. Less well-understood are the hormonal mechanisms involved in response to vocal cues, and how these systems may influence the course of behavioural evolution. The neurohormone oxytocin (OT) partly governs a number of biological and social processes critical to fitness, such as attachment between mothers and their young, and suppression of the stress response after contact with trusted conspecfics. Rodent studies suggest that OT's release is contingent upon direct tactile contact with such individuals, but we hypothesized that vocalizations might be capable of producing the same effect. To test our hypothesis, we chose human mother-daughter dyads and applied a social stressor to the children, following which we randomly assigned participants into complete contact, speech-only or no-con…

Exploring the relationships between trait emotional intelligence and objective socio-emotional outcomes in childhood.

Background: Trait emotional intelligence (trait EI or trait emotional self-efficacy) is a constellation of emotion-related self-perceptions and dispositions located at the lower levels of personality hierarchies. This paper examines the validity of this construct, as operationalized by the Trait Emotional Intelligence Questionnaire-Child Form (TEIQue-CF), in primary schoolchildren. Aims: The main aim was to examine the construct validity of trait EI in middle and late childhood by exploring its relationships with cognitive ability, emotion perception, and social behaviour. Sample: The sample comprised 140 children aged between 8 and 12 years (M=9.26 years, SD=1.00 year; 63 girls) from two English state primary schools. Method: Pupils completed the TEIQue-CF, the standard progressive matrices (SPM), the guess who peer assessment, the social skills training (SST) test, and the assessment o…

Individual attachment style modulates human amygdala and striatum activation during social appraisal.

Adult attachment style refers to individual personality traits that strongly influence emotional bonds and reactions to social partners. Behavioral research has shown that adult attachment style reflects profound differences in sensitivity to social signals of support or conflict, but the neural substrates underlying such differences remain unsettled. Using functional magnetic resonance imaging (fMRI), we examined how the three classic prototypes of attachment style (secure, avoidant, anxious) modulate brain responses to facial expressions conveying either positive or negative feedback about task performance (either supportive or hostile) in a social game context. Activation of striatum and ventral tegmental area was enhanced to positive feedback signaled by a smiling face, but this was reduced in participants with avoidant attachment, indicating relative impassiveness to social reward. …

The neural bases of emotion regulation: reappraisal and suppression of negative emotion.

Background: Emotion regulation strategies are thought to differ in when and how they influence the emotion-generative process. However, no study to date has directly probed the neural bases of two contrasting (e.g., cognitive versus behavioral) emotion regulation strategies. This study used functional magnetic resonance imaging (fMRI) to examine cognitive reappraisal (a cognitive strategy thought to have its impact early in the emotion-generative process) and expressive suppression (a behavioral strategy thought to have its impact later in the emotion-generative process). Methods: Seventeen women viewed 15 sec neutral and negative emotion-eliciting films under four conditions--watch-neutral, watch-negative, reappraise-negative, and suppress-negative--while providing emotion experience ratings and having their facial expressions videotaped. Results: Reappraisal resulted in early (0-4.5 se…
