Qur'ān 49:12Arabic sense: الظن, تجسسوا
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
Qur'ān 2:235Arabic sense: يعلم ما في انفسكم
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
Qur'ān 3:119Arabic sense: بذات الصدور
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

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

2051 to 2075 of 2,381A Non-bipartite Propensity Score Analysis of the Effects of Teacher-Student Relationships on Adolescent Problem and Prosocial Behavior.
Previous research suggests a link between the quality of teacher-student relationships and the students' behavioral outcomes; however, the observational nature of past studies makes it difficult to attribute a causal role to the quality of these relationships. In the current study, therefore, we used a propensity score analysis approach to evaluate whether students who were matched on their propensity to experience a given level of relationship quality but differed on their actual relationship quality diverged on their concurrent and subsequent problem and prosocial behavior. Student/self, teacher, and parent- (only waves 1-3) reported data from 8 waves of the Zurich Project on the Social Development of Children and Youths (z-proso), a longitudinal study of Swiss youth among a culturally diverse sample of 7- to 15-year-olds were utilized. The initial sample included 1483 (49.4 % female) …

Social isolation and loneliness: Prospective associations with functional status in older adults.
Objective: The present analysis aimed to examine the associations of isolation and loneliness, individually as well as simultaneously, with 2 measures of functional status (gait speed and difficulties in activities of daily living) in older adults over a 6-year period using data from the English Longitudinal Study of Ageing, and to assess if these associations differ by SES.
Method: Loneliness was measured using the short form of the Revised UCLA scale, and an index of social isolation was computed incorporating marital status; frequency of contact with friends, family, and children; and participation in social activities. Measures of functional status were assessed identically at baseline and 6 years later for 3070 participants (mean age 69 years). Wealth was used as an indicator of SES.
Results: In fully and mutually adjusted models, social isolation and loneliness were found to be ass…

Social Media Use, Friendship Quality, and the Moderating Role of Anxiety in Adolescents with Autism Spectrum Disorder.
Social media holds promise as a technology to facilitate social engagement, but may displace offline social activities. Adolescents with ASD are well suited to capitalize on the unique features of social media, which requires less decoding of complex social information. In this cross-sectional study, we assessed social media use, anxiety and friendship quality in 44 adolescents with ASD, and 56 clinical comparison controls. Social media use was significantly associated with high friendship quality in adolescents with ASD, which was moderated by the adolescents' anxiety levels. No associations were founds between social media use, anxiety and friendship quality in the controls. Social media may be a way for adolescents with ASD without significant anxiety to improve the quality of their friendships.

Promoting social capital to alleviate loneliness and improve health among older people in Spain.
Loneliness is especially frequent among older people in Southern Europe. Furthermore, promoting social capital to tackle loneliness and its health effects is an understudied intervention strategy. Therefore, a complex intervention was piloted in Spain in a pre-post study with a 2-year follow-up. Its aims were to explore the feasibility of the intervention and its short- and long-term effects. It was conducted in one mixed rural-urban and two urban areas of diverse socioeconomic levels from 2011 to 2012. The intervention framework was based on social capital theory applying a behaviour change model and care co-ordination. The intervention comprised: (i) a co-ordinated action aimed at building a network between primary healthcare centres and community assets in the neighbourhood and (ii) a group-based programme, which promoted social capital among lonely older people, especially social sup…

Viral infection during pregnancy is correlated with increased frequency of neurodevelopmental disorders, and this is studied in mice prenatally subjected to maternal immune activation (MIA). We previously showed that maternal T helper 17 cells promote the development of cortical and behavioural abnormalities in MIA-affected offspring. Here we show that cortical abnormalities are preferentially localized to a region encompassing the dysgranular zone of the primary somatosensory cortex (S1DZ). Moreover, activation of pyramidal neurons in this cortical region was sufficient to induce MIA-associated behavioural phenotypes in wild-type animals, whereas reduction in neural activity rescued the behavioural abnormalities in MIA-affected offspring. Sociability and repetitive behavioural phenotypes could be selectively modulated according to the efferent targets of S1DZ. Our work identifies a cort…

Stereotypes, Emotions, and Behaviors Toward Lesbians, Gay Men, Bisexual Women, and Bisexual Men.
The utility of the Stereotype Content Model (Fiske, Cuddy, Glick, & Xu, 2002) and the Behaviors from Intergroup Affect and Stereotypes map (Cuddy, Fiske, & Glick, 2007) were examined in the context of heterosexuals' attitudes toward sexual minorities. Heterosexual adults completed a survey measuring stereotypes, emotions, and behavioral tendencies toward lesbians, gay men, bisexual women, and bisexual men. Stereotype content differed across groups and showed "gendered" and "valenced" effects on emotions and behavioral tendencies. Competence predicted behaviors for men, whereas warmth and competence predicted behaviors for women, and, for the most part, more was better. Admiration and contempt mediated most of these relationships across most subgroups, but pity and envy played smaller roles for some subgroups. Across all groups, competence played a more predictive role than warmth.

Functional significance of rare neuroligin 1 variants found in autism.
Genetic mutations contribute to the etiology of autism spectrum disorder (ASD), a common, heterogeneous neurodevelopmental disorder characterized by impairments in social interaction, communication, and repetitive and restricted patterns of behavior. Since neuroligin3 (NLGN3), a cell adhesion molecule at the neuronal synapse, was first identified as a risk gene for ASD, several additional variants in NLGN3 and NLGN4 were found in ASD patients. Moreover, synaptopathies are now known to cause several neuropsychiatric disorders including ASD. In humans, NLGNs consist of five family members, and neuroligin1 (NLGN1) is a major component forming a complex on excitatory glutamatergic synapses. However, the significance of NLGN1 in neuropsychiatric disorders remains unknown. Here, we systematically examine five missense variants of NLGN1 that were detected in ASD patients, and show molecular and…

Autism spectrum disorder (ASD) comprises a range of neurodevelopmental disorders characterized by deficits in social interaction and communication as well as by restricted and repetitive behaviours. ASD has a strong genetic component with high heritability. Exome sequencing analysis has recently identified many de novo mutations in a variety of genes in individuals with ASD, with CHD8, a gene encoding a chromatin remodeller, being most frequently affected. Whether CHD8 mutations are causative for ASD and how they might establish ASD traits have remained unknown. Here we show that mice heterozygous for Chd8 mutations manifest ASD-like behavioural characteristics including increased anxiety, repetitive behaviour, and altered social behaviour. CHD8 haploinsufficiency did not result in prominent changes in the expression of a few specific genes but instead gave rise to small but global chang…

How People Use Social Information to Find out What to Want in the Paradigmatic Case of Inter-temporal Preferences.
The weight with which a specific outcome feature contributes to preference quantifies a person's 'taste' for that feature. However, far from being fixed personality characteristics, tastes are plastic. They tend to align, for example, with those of others even if such conformity is not rewarded. We hypothesised that people can be uncertain about their tastes. Personal tastes are therefore uncertain beliefs. People can thus learn about them by considering evidence, such as the preferences of relevant others, and then performing Bayesian updating. If a person's choice variability reflects uncertainty, as in random-preference models, then a signature of Bayesian updating is that the degree of taste change should correlate with that person's choice variability. Temporal discounting coefficients are an important example of taste-for patience. These coefficients quantify impulsivity, have good…

Neural correlates of social exchanges during the Prisoner's Dilemma game in depression.
Background: Depression is a disabling disorder that significantly impacts on the interpersonal functioning of individuals. However, little is known about the neural substrates of such difficulties. In the last few years neuroeconomics, which combines imaging with multiplayer behavioural economic paradigms, has been used to study the neural substrates of normal and abnormal interpersonal interactions.
Method: This study used functional magnetic resonance imaging to investigate neural activity in unmedicated depressed participants (n = 25) and matched healthy controls (n = 25). During scanning, participants played a behavioural economic game, the Prisoner's Dilemma. In this game, the participant and a co-player independently choose either to cooperate or not cooperate with each other.
Results: Depressed participants reported higher levels of negative feelings (betrayal, guilt) during the g…

The nature of prosociality in chimpanzees.
An important debate centres around the nature of prosociality in nonhuman primates. Chimpanzees help other individuals in some experimental settings, yet they do not readily share food. One solution to this paradox is that they are motivated to help others provided there are no competing interests. However, benefits to recipients could arise as by-products of testing. Here we report two studies that separate by-product from intended helping in chimpanzees using a GO/NO-GO paradigm. Actors in one group could help a recipient by releasing a food box, but the same action for another group prevented a recipient from being able to get food. We find no evidence for helping-chimpanzees engaged in the test regardless of the effects on their partners. Illusory prosocial behaviour could arise as a by-product of task design.

Association between Social Integration and Health among Internal Migrants in ZhongShan, China.
Internal migrants are the individuals who migrate between regions in one country. The number of internal migrants were estimated at 245 million in China in 2013. Results were inconsistent in the literature about the relationship between their health statuses and social integration. The main difference exists on how to measure the social integration and whether health statuses of internal migrants improve with years of residence. To complement the existing literature, this study measured social integration more comprehensively and estimated the internal migrants' health statuses with varying years of residence, and explored the associations between the migrants' social integration and health. We used the data from 2014 Internal Migrant Dynamic Monitoring Survey of Health and Family Planning in ZhongShan, China. Health status was measured from four aspects: self-reported health, subjective…

Neuroinflammatory Dynamics Underlie Memory Impairments after Repeated Social Defeat.
Repeated social defeat (RSD) is a murine stressor that recapitulates key physiological, immunological, and behavioral alterations observed in humans exposed to chronic psychosocial stress. Psychosocial stress promotes prolonged behavioral adaptations that are associated with neuroinflammatory signaling and impaired neuroplasticity. Here, we show that RSD promoted hippocampal neuroinflammatory activation that was characterized by proinflammatory gene expression and by microglia activation and monocyte trafficking that was particularly pronounced within the caudal extent of the hippocampus. Because the hippocampus is a key area involved in neuroplasticity, behavior, and cognition, we hypothesize that stress-induced neuroinflammation impairs hippocampal neurogenesis and promotes cognitive and affective behavioral deficits. We show here that RSD caused transient impairments in spatial memory…

Cool and hot executive function as predictors of aggression in early childhood: Differentiating between the function and form of aggression.
Executive function (EF) has been implicated in childhood aggression. Understanding of the role of EF in aggression has been hindered, however, by the lack of research taking into account the function and form of aggression and the almost exclusive focus on cool EF. This study examined the role of cool and hot EF in teacher reported aggression, differentiating between reactive and proactive as well as physical and relational aggression. Children (N = 106) completed laboratory tasks measuring cool (inhibition, planning, working memory) and hot EF (affective decision-making, delay of gratification). Cool, but not hot, EF significantly contributed to understanding of childhood aggression. Inhibition was a central predictor of childhood aggression. Planning and working memory, in contrast, were significant independent predictors of proactive relational aggression only. Added to this, prosocia…

Gender differences in use and expectancies of e-cigarettes: Online survey results.
Introduction: Given the rapid increase in e-cigarette use, it is important to understand factors that may contribute to their initiation and maintenance. Because gender differences in tobacco use, product preferences, and expectancies are well established, similar gender differences may exist with e-cigarettes. The aim of this study was to identify gender differences among e-cigarette users in patterns of use, reasons for initiation and maintenance, and outcome expectancies regarding e-cigarettes.
Methods: Participants (N=1815) completed an online survey from August through November, 2013. We assessed sociodemographics, smoking and e-cigarette history and use, and expectancies about e-cigarettes.
Results: We found gender differences in type of e-cigarette used, flavors used, nicotine dosage, source of information about e-cigarettes, place of purchase, and use of e-cigarettes where smokin…

Dual Trajectories of Reactive and Proactive Aggression from Mid-childhood to Early Adolescence: Relations to Sensation Seeking, Risk Taking, and Moral Reasoning.
We examined the roles of sensation seeking, risk taking, and moral reasoning in the development of reactive and proactive aggression. Data were drawn from a multiethnic, longitudinal study of children from Switzerland (N = 1571; 52 % male; assessed annually over 6 years; 7-years-old at Time 1). At all 6 time points, teachers reported children's reactive and proactive aggression via questionnaire. Children's sensation seeking (at Time 1) and risk taking (at Time 2) were assessed with two interactive computer tasks and their moral reasoning was assessed at Time 2 in response to four hypothetical vignettes depicting moral transgressions. Parallel process Latent Class Growth Analysis (PP-LCGA) identified six dual trajectories of reactive and proactive aggression. Children with either childhood-limited or adolescent-onset aggression showed high sensation seeking. Children with persistent, hig…

Delay discounting, risk-taking, and rejection sensitivity among individuals with Internet and Video Gaming Disorders.
Background and aims There is a previous evidence for impulsivity in individuals with Internet and Video Gaming Disorders. The aim of this study was to examine whether Internet and video game addictions are associated with experiential delay discounting, risk-taking, and sensitivity to social rejection using computerized tasks and questionnaires. Methods Twenty participants (mean age 24, SD = 1.55) with high score on the Problematic Online Gaming Questionnaire (POGQ) were compared with 20 participants (mean age 24.8, SD = 1.34) with low score on the POGQ. They performed on computerized Balloon Analog Risk Task and Experiential Delay discounting Task (EDT), and filled in the sensitivity to social rejection questionnaire. Results Participants with high POGQ scores had lower measures of delay discounting, higher measures of risk-taking, and higher measures of sensitivity to social rejection …

Tend to Compare and Tend to Be Fair: The Relationship between Social Comparison Sensitivity and Justice Sensitivity.
Social comparison is a prerequisite for processing fairness, although the two types of cognition may be associated with different emotions. Whereas social comparison may induce envy, the perception of unfairness may elicit anger. Yet, it remains unclear whether people who tend to have a strong sense of fairness also tend to compare themselves more with others. Here, Study 1 used a modified ultimatum game (UG) and a social comparison game (SCG) to examine the relationship between justice sensitivity and social comparison sensitivity in 51 young adults. Study 2 examined self-reported social comparison and justice sensitivity in 142 young adults. Both studies showed a positive correlation between social comparison sensitivity and justice sensitivity. We reason that social comparison and justice sensitivity have an important positive correlation in human decision-making. The rejection of sel…

Increased social anhedonia and reduced helping behaviour in young people with high depressive symptomatology.
Background: Social anhedonia, the decreased enjoyment of pleasant social experiences, is associated with depression. However, whether social anhedonia in depression affects prosocial behaviours is unclear. The current study aimed to examine how high levels of depressive symptomatology in young people affect responses to usually rewarding social situations, including helping behaviour.
Methods: We recruited 46 females, 16 scoring high on the Beck Depression Inventory (BDI scores>20, Mage=19; HD) and 30 scoring low (BDI<10, Mage=20; LD). In a social emotion task (SET), participants were presented with social scenarios and asked to rate their expected emotional responses. Subsequently, participants' helping behaviour was measured by dropping a pile of papers near them and recording their responses. Lastly, participants completed the SET again.
Results: The SET at time 1 revealed that HD ind…

Bidirectional modulation of anxiety-related and social behaviors by amygdala projections to the medial prefrontal cortex.
The basolateral amygdala (BLA) and the medial prefrontal cortex (mPFC) modulate anxiety and social behaviors. It remains to be elucidated, however, whether direct projections from the BLA to the mPFC play a functional role in these behaviors. We used optogenetic approaches in behaving mice to either activate or inhibit BLA inputs to the mPFC during behavioral assays that assess anxiety-like behavior and social interaction. Channelrhodopsin-2 (ChR2)-mediated activation of BLA inputs to the mPFC produced anxiogenic effects in the elevated plus maze and open field test, whereas halorhodopsin (NpHR)-mediated inhibition produced anxiolytic effects. Furthermore, activation of the BLA-mPFC pathway reduced social interaction in the resident-intruder test, whereas inhibition facilitated social interaction. These results establish a causal relationship between activity in the BLA-mPFC pathway and …

Ever since the emergence of social networking sites (SNSs), it has remained a question without a conclusive answer whether SNSs make people more or less lonely. To achieve a better understanding, researchers need to move beyond studying overall SNS usage. In addition, it is necessary to attend to personal attributes as potential moderators. Given that SNSs provide rich opportunities for social comparison, one highly relevant personality trait would be social comparison orientation (SCO), and yet this personal attribute has been understudied in social media research. Drawing on literature of psychosocial implications of social media use and SCO, this study explored associations between loneliness and various Instagram activities and the role of SCO in this context. A total of 208 undergraduate students attending a U.S. mid-southern university completed a self-report survey (Mage = 19.43, …

Age-related changes in behavior in C57BL/6J mice from young adulthood to middle age.
Background: Aging is considered to be associated with progressive changes in the brain and its associated sensory, motor, and cognitive functions. A large number of studies comparing young and aged animals have reported differences in various behaviors between age-cohorts, indicating behavioral dysfunctions related to aging. However, relatively little is known about behavioral changes from young adulthood to middle age, and the effect of age on behavior during the early stages of life remains to be understood. In order to investigate age-related changes in the behaviors of mice from young adulthood to middle age, we performed a large-scale analysis of the behavioral data obtained from our behavioral test battery involving 1739 C57BL/6J wild-type mice at 2-12 months of age.

Adult restoration of Shank3 expression rescues selective autistic-like phenotypes.
Because autism spectrum disorders are neurodevelopmental disorders and patients typically display symptoms before the age of three, one of the key questions in autism research is whether the pathology is reversible in adults. Here we investigate the developmental requirement of Shank3 in mice, a prominent monogenic autism gene that is estimated to contribute to approximately 1% of all autism spectrum disorder cases. SHANK3 is a postsynaptic scaffold protein that regulates synaptic development, function and plasticity by orchestrating the assembly of postsynaptic density macromolecular signalling complex. Disruptions of the Shank3 gene in mouse models have resulted in synaptic defects and autistic-like behaviours including anxiety, social interaction deficits, and repetitive behaviour. We generated a novel Shank3 conditional knock-in mouse model, and show that re-expression of the Shank3 …

Who strikes back? A daily investigation of when and why incivility begets incivility.
Incivility at work-low intensity deviant behaviors with an ambiguous intent to harm-has been on the rise, yielding negative consequences for employees' well-being and companies' bottom-lines. Although examinations of incivility have gained momentum in organizational research, theory and empirical tests involving dynamic, within-person processes associated with this negative interpersonal behavior are limited. Drawing from ego depletion theory, we test how experiencing incivility precipitates instigating incivility toward others at work via reduced self-control. Using an experience sampling design across 2 work weeks, we found that experiencing incivility earlier in the day reduced one's levels of self-control (captured via a performance-based measure of self-control), which in turn resulted in increased instigated incivility later in the day. Moreover, organizational politics-a stable, e…
