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

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

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

1926 to 1950 of 2,381The two-way relationship of interpersonal curiosity and daily envy.
Objective: Envy and interpersonal curiosity are common emotional and psychological phenomena in relationships that collectively influence our social behavior and experiences. However, there is a research gap regarding the interaction between interpersonal curiosity and envy. Therefore, this study will primarily utilize daily diary methods to investigate the relationship between interpersonal curiosity and envy.
Method: Using the Benign and Malicious Envy Scale and the Chinese Adolescents' Interpersonal Curiosity Questionnaire, Study 1 conducted a preliminary study on 392 middle school students using cross-sectional data. Based on the data from Study 1, we selected the ten items (2 items per variable) with the highest factor load for the daily measurement of Study 2. Study 2 utilized the diary method and recruited 81 adolescents as participants for a 14-day measurement period.
Results: Th…

Religious coping and delinquent behaviors: Moderated mediation roles of religion affiliation and prosocial moral reasoning.
Religion has been shown to have a positive impact for developing adolescents; however, the processes underlying this relation are not well known. In his almighty prosocial theory, Anazonwu (Conceptualizing and testing almighty prosociality theory for a more peaceful world, SCOA Heritage Nigeria, 2017) proposed that the activation of learnt prosocial moral reasoning through religion enabled performance of prosocial peace behavior that will benefit society. Thus, religion coping enhances the development of prosocial reasoning which in turn propagate prosocial acts while reducing delinquent behaviors. Similarly, developmental system theory (Lerner, Developmental science, developmental systems, and contemporary theories of human development, John Wiley & Sons, 2006) assumed that in every individual three mechanisms: plasticity (potential to change), context (environment), and developmental r…

Human ventromedial prefrontal cortex is necessary for prosocial motivation.
Ventromedial prefrontal cortex (vmPFC) is vital for decision-making. Functional neuroimaging links vmPFC to processing rewards and effort, while parallel work suggests vmPFC involvement in prosocial behaviour. However, the necessity of vmPFC for these functions is unknown. Patients with rare focal vmPFC lesions (n = 25), patients with lesions elsewhere (n = 15) and healthy controls (n = 40) chose between rest and exerting effort to earn rewards for themselves or another person. vmPFC damage decreased prosociality across behavioural and computational measures. vmPFC patients earned less, discounted rewards by effort more, and exerted less force when another person benefited, compared to both control groups. Voxel-based lesion mapping revealed dissociations between vmPFC subregions. While medial damage led to antisocial behaviour, lateral damage increased prosocial behaviour relative to pa…

Adverse childhood experiences and externalizing, internalizing, and prosocial behaviors in children and adolescents: A longitudinal study.
Background: Adverse childhood experiences (ACEs) have a profound impact on individuals, shaping their long-term health and life opportunities. This study delves into the complex ties between ACEs and the socioemotional development of Australian children and youth by examining the relationships between adverse childhood experiences and externalizing, internalizing, and prosocial behaviors.
Methods: This study utilized data from the Longitudinal Study of Australian Children and employed the generalized estimating equation method to investigate the relationships between adverse childhood experiences and externalizing, internalizing, and prosocial behaviors in Australian children and adolescents.
Results: Adverse childhood experiences such as physical punishment, hostile parenting, parental conflicts, separation, financial strain, and parental mental health issues increased the risk of exter…

Sex differences in the social motivation of rats: Insights from social operant conditioning, behavioural economics, and video tracking.
Background: Social behaviour plays a key role in mental health and wellbeing, and developing greater understanding of mechanisms underlying social interaction-particularly social motivation-holds substantial transdiagnostic impact. Common rodent behavioural assays used to assess social behaviour are limited in their assessment of social motivation, whereas the social operant conditioning model can provide unique and valuable insights into social motivation. Further characterisation of common experimental parameters that may influence social motivation within the social operant model, as well as complementary methodological and analytical approaches, are warranted.
Methods: This study investigated the effects of biological sex, housing condition, and time-of-day, on social motivation using the social operant model. This involved training rats to lever press (FR1) for 60-s access to a soci…

Naloxone increases conditioned fear responses during social buffering in male rats.
Social buffering is the phenomenon in which the presence of an affiliative conspecific mitigates stress responses. We previously demonstrated that social buffering completely ameliorates conditioned fear responses in rats. However, the neuromodulators involved in social buffering are poorly understood. Given that opioids, dopamine, oxytocin and vasopressin play an important role in affiliative behaviour, here, we assessed the effects of the most well-known antagonists, naloxone (opioid receptor antagonist), haloperidol (dopamine D2 receptor antagonist), atosiban (oxytocin receptor antagonist) and SR49059 (vasopressin V1a receptor antagonist), on social buffering. In Experiment 1, fear-conditioned male subjects were intraperitoneally administered one of the four antagonists 25 min prior to exposure to a conditioned stimulus with an unfamiliar non-conditioned rat. Naloxone, but not the oth…

Do body colour and sociability impact scototaxis response of fish?
Scototaxis test is an anxiety-like test used by behavioural neuroscientists consisting in the assessment of dark/light preference of laboratory animals. This test has been widely used in fish. Most of the species have been shown to express a preference for the dark environment. However, the majority of the investigated species has a dark body colour, thus making a clear contrast with a white/bright background. Also, while in nature fish tend to be highly social, studies in the scototaxis literature tested single fish. Yet, individual vs. group behaviour might interact with scototaxis response. In experiment 1, we assessed the individual response to test the hypothesis that the different colours of the body might modulate the dark/light preference. We found that species with a dark body colour (Hyphessobrycon megalopterus) and a largely transparent body colour (Kryptopterus bicirrhis) str…

Bidirectional relations between altruistic tendency and benign/malicious envy among adolescents: A longitudinal study and weekly diary study.
Altruism is a prosocial tendency that has developed through long-term evolutionary selection. The present study adopts social comparison and evolutionary psychology theories to examine how benign/malicious envy can affect altruism and how altruism can affect the two types of envy in turn, respectively. In Study 1, 513 adolescents participated in a three-wave longitudinal survey to explore the relationships between dispositional altruistic tendency and dispositional benign/malicious envy. The cross-lagged analysis showed a long-term and stable negative bidirectional relationship between dispositional altruistic tendency and dispositional malicious envy and a short-term positive bidirectional relationship between dispositional altruism and dispositional benign envy. In Study 2, 109 adolescents kept a weekly diary for seven consecutive weeks to record state levels of altruistic tendency and…

Suss JH (2023)MEDLINE-indexed journal, not yet read by usPloS one2 citations Higher income individuals are more generous when local economic inequality is high.
There is ongoing debate about whether the relationship between income and pro-social behaviour depends on economic inequality. Studies investigating this question differ in their conclusions but are consistent in measuring inequality at aggregated geographic levels (i.e. at the state, region, or country-level). I hypothesise that local, more immediate manifestations of inequality are important for driving pro-social behaviour, and test the interaction between income and inequality at a much finer geographical resolution than previous studies. I first analyse the charitable giving of US households using ZIP-code level measures of inequality and data on tax deductible charitable donations reported to the IRS. I then examine whether the results generalise using a large-scale UK household survey and neighbourhood-level inequality measures. In both samples I find robust evidence of a signific…

The warm glow of kindness: Developmental insight into children's moral pride across cultures and its associations with prosocial behavior.
Moral pride is a key component of virtue development. This study provides developmental insight into children's moral pride across cultures, and the potential for moral pride to underlie prosocial behavior. Participants included children and adolescents ages 6, 9, and 12 years from Canada (n = 186; 50% girls; ethnically diverse sample), Japan (n = 180; 48% girls), and a subsample from Italy (n = 86; 54% girls), as well as their primary caregivers or teachers. Moral pride was measured using a vignette procedure wherein children reported their emotions, emotion intensities, and reasoning following moral actions (harm omission and prosocial contexts). Global prosocial behavior was assessed via caregiver reports. Results revealed that moral pride increased from 6 to 9 years of age in Japanese and Canadian children (some similar trends were found in the Italian subsample) and that Canadian ch…

Prolonged partner separation erodes nucleus accumbens transcriptional signatures of pair bonding in male prairie voles.
The loss of a spouse is often cited as the most traumatic event in a person's life. However, for most people, the severity of grief and its maladaptive effects subside over time via an understudied adaptive process. Like humans, socially monogamous prairie voles (Microtus ochrogaster) form opposite-sex pair bonds, and upon partner separation, show stress phenotypes that diminish over time. We test the hypothesis that extended partner separation diminishes pair bond-associated behaviors and causes pair bond transcriptional signatures to erode. Opposite-sex or same-sex paired males were cohoused for 2 weeks and then either remained paired or were separated for 48 hours or 4 weeks before collecting fresh nucleus accumbens tissue for RNAseq. In a separate cohort, we assessed partner-directed affiliation at these time points. We found that these behaviors persist despite prolonged separation …

No one is an island: Awe encourages global citizenship identification.
Recent theorizing has suggested that awe is a collective emotion, as research has demonstrated a clear link between experiencing awe and behaving prosocially. The present research extends past work by investigating the scope and sources of awe-inspired prosociality, focusing on whether awe's effects extend beyond local/national interests to include global or humanitarian goals. Specifically, we examine how by increasing feelings of smallness, awe encourages a sense of global citizenship, promoting cosmopolitan (vs. parochial) prosociality. Four experiments found that varied awe elicitors (recall, pictures, videos) and cues (universe, peaceful/fearful nature scenes) boost global citizenship identification by first increasing perception of the self as small. Downstream effects included greater valuing of interconnectedness (Experiment 2) and higher appreciation of diversity (Experiment 3).…

Qualitative differences in perspective on children's quality of life between children with cerebral palsy and their parents.
Background: Cerebral palsy (CP) is one of the most common childhood disabilities, impacting many areas of a child's life. Increasingly, quality of life (QOL) measures are used to capture holistic wellbeing of children with CP. However most validated QOL measures for children are based on adult perspective only, with limited focus on child perspective. Conceptual differences between children's and adults' definitions of QOL may reflect different underlying QOL models which contribute to measurement score divergence. This qualitative study investigated the conceptual meaning of QOL for children with CP, comparing child and parent perspectives. Eighteen families completed 8 child interviews and 18 parent interviews. Children (11 boys, 7 girls) represented the spectrum of motor functioning, with comorbidities including epilepsy, intellectual disability, and communication impairments. Child a…

Characterization of Pan social systems reveals in-group/out-group distinction and out-group tolerance in bonobos.
Human between-group interactions are highly variable, ranging from violent to tolerant and affiliative. Tolerance between groups is linked to our unique capacity for large-scale cooperation and cumulative culture, but its evolutionary origins are understudied. In chimpanzees, one of our closest living relatives, predominantly hostile between-group interactions impede cooperation and information flow across groups. In contrast, in our other closest living relative, the bonobo, tolerant between-group associations are observed. However, as these associations can be frequent and prolonged and involve social interactions that mirror those within groups, it is unclear whether these bonobos really do belong to separate groups. Alternatively, the bonobo grouping patterns may be homologous to observations from the large Ngogo chimpanzee community, where individuals form within-group neighborhoods…

How individuals react emotionally to others' (mis)fortunes: A social comparison framework.
When confronted with others' fortunes and misfortunes, emotional reactions can take various forms-ranging from assimilative (happy-for-ness, sympathy) to contrastive emotions (envy, schadenfreude) and from prosocial (reward) to antisocial behavior (punish). We systematically tested how social comparisons shape reactions to others' (mis)fortunes with a newly developed paradigm with which we investigated envy, happy-for-ness, schadenfreude, and sympathy in a joint rigorous experimental setup, along with individuals' ensuing behavioral reactions. In nine experiments (Ntotal = 1,827), (a) participants' rankings on a comparison dimension relative to other people and (b) others' (mis)fortunes (changes in relative rankings) jointly determined how much individuals experienced the emotions. Upward comparisons increased envy and schadenfreude, and downward comparisons increased sympathy and happy-…

Psychosocial Adjustment in Emerging Adults With and Without Spina Bifida: A 14-Year Follow-up Study.
Objective: A 14-year follow-up of youth with spina bifida (SB), as compared to a matched comparison sample without a chronic health condition, focused on psychosocial adjustment during emerging adulthood (ages 22-23).
Methods: The initial cohort at time 1 consisted of 68 families with an 8-year-old or 9-year-old child with SB and a matched comparison sample of 68 typically developing children and their families. At the final assessment (time 7), participants included 56 emerging adults with SB (82% of those who participated at time 1) and 62 comparison youth (91% of those who participated at time 1) who completed a set of self-report measures.
Results: Emerging adults with SB continue to lag behind across several important developmental milestones, including decision-making responsibility, involvement in social and romantic relationships, sexual intimacy, educational and vocational achie…

Lakew N (2022)MEDLINE-indexed journal, not yet read by usJournal of gambling studies9 citations "Show Me the Money": Preliminary Lessons from an Implementation of Intervention Tools at the Payment Gateway Level.
Traditional approaches that seek to study Responsible Gambling (RG) mainly focus on evaluating platform-based intervention tools applied on gambling operator sites. This paper reports on the implementation, at the payment-solution level, of an intervention tool that gambling customers used to deposit their bets. The approach pre-commits customers to set a single-point spending limit on their payment gateway account, effectively enabling them to apply their budget setting on all gambling platforms on which they choose to play. Ten users who have used the provision for at least six months and on two different gambling platforms were selected for an in-depth interview. Based on the findings from content analysis, the article argues that payment-level intervention approach can potentially (1) provide the overall gambling population with better financial literacy regarding their gambling habi…

Foraging networks and social tolerance in a cooperatively breeding primate (Callithrix jacchus).
Within-group competition over food resources can be a major cost of social living. In the wild, foragers are confronted with social (e.g. hierarchical rank) and ecological (e.g. food availability and distribution) challenges that affect their foraging decisions and feeding success. Exhibiting prosocial behaviours, such as tolerance at feeding sites, can benefit group members by developing affiliative social relationships, enhancing access to resources and maximizing fitness. We examined social tolerance at feeding sites in Callithrix jacchus, a cooperatively breeding primate species. We investigated the set of social (rank, age and sex) and ecological (food availability) factors that influence the structure and dynamics of within-group foraging association networks. We designed and conducted an experimental field study of four wild groups of common marmosets in which we controlled food d…

Behavioral trajectories of aging prairie voles (Microtus ochrogaster): Adapting behavior to social context wanes with advanced age.
Several studies using mice have examined the effects of aging on cognitive tasks, as well as sensory and motor functions. However, few studies have examined the influence of aging on social behavior. Prairie voles (Microtus ochrogaster) are a socially monogamous and biparental rodent that live in small family groups and are now among the most popular rodent models for studies examining social behavior. Although the social behavioral trajectories of early-life development in prairie voles have been well-studied, how social behavior may change throughout adulthood remains unknown. Here we examined behavior in virgin male and female prairie voles in four different age groups: postnatal day (PND) 60-80, 140-160, 220-240, and 300-320. All animals underwent testing in a novel object task, a dominance test, a resident-intruder test, and several iterations of social approach and social interacti…

Interpersonal distance modulates the influence of social observation on prosocial behaviour: An event-related potential (ERP) study.
This study aimed to explore the influence of interpersonal distance and social observation on prosocial behaviour. Participants were instructed to make costly prosocial decisions towards different interpersonal distance targets (friends, acquaintances or strangers) under the (non) observable condition, with simultaneous electroencephalogram recording. The behavioural results demonstrated that participants made more prosocial choices-unaffected by social observation-towards friends than towards acquaintances and strangers; nonetheless, participants made more prosocial choices towards acquaintances and strangers under the observable than under the non-observable condition. Event-related potential results showed that when participants made prosocial decisions towards friends, the P3 and N2 amplitudes remained unchanged between the observable and non-observable conditions; however, when part…

Delegation to artificial agents fosters prosocial behaviors in the collective risk dilemma.
Home assistant chat-bots, self-driving cars, drones or automated negotiation systems are some of the several examples of autonomous (artificial) agents that have pervaded our society. These agents enable the automation of multiple tasks, saving time and (human) effort. However, their presence in social settings raises the need for a better understanding of their effect on social interactions and how they may be used to enhance cooperation towards the public good, instead of hindering it. To this end, we present an experimental study of human delegation to autonomous agents and hybrid human-agent interactions centered on a non-linear public goods dilemma with uncertain returns in which participants face a collective risk. Our aim is to understand experimentally whether the presence of autonomous agents has a positive or negative impact on social behaviour, equality and cooperation in such…

Neural control of affiliative touch in prosocial interaction.
The ability to help and care for others fosters social cohesiveness and is vital to the physical and emotional well-being of social species, including humans1-3. Affiliative social touch, such as allogrooming (grooming behaviour directed towards another individual), is a major type of prosocial behaviour that provides comfort to others1-6. Affiliative touch serves to establish and strengthen social bonds between animals and can help to console distressed conspecifics. However, the neural circuits that promote prosocial affiliative touch have remained unclear. Here we show that mice exhibit affiliative allogrooming behaviour towards distressed partners, providing a consoling effect. The increase in allogrooming occurs in response to different types of stressors and can be elicited by olfactory cues from distressed individuals. Using microendoscopic calcium imaging, we find that neural act…

Majority and popularity effects on norm formation in adolescence.
Personal norms consist of individuals' attitudes about the appropriateness of behaviour. These norms guide adolescents' behaviour in countless domains that are fundamental for their social functioning and well-being. Peers are known to have a marked influence on adolescent risk-taking and prosocial behaviour, but little is known about how peers shape personal norms underlying those behaviours. Here we show that adolescents' personal norms are decisively moulded by the norms of the majority and popular peers in their social network. Our experiment indicates that observing peer norms substantially impacts adolescents' normative evaluation of risk-taking and prosocial behaviours. The majority norm had a stronger impact than the norm of a single popular peer, and norm adjustments were largest when adolescents observed strong disapproval of risk-taking or strong approval of prosocial behaviou…

Infectious or noninfectious maternal immune activation (MIA) is an environmental risk factor for psychiatric and neurological disorders with neurodevelopmental etiologies. Whilst there is increasing evidence for significant health consequences, the effects of MIA on the offspring appear to be variable. Here, we aimed to identify and characterize subgroups of isogenic mouse offspring exposed to identical MIA, which was induced in C57BL6/N mice by administration of the viral mimetic, poly(I:C), on gestation day 12. Cluster analysis of behavioral data obtained from a first cohort containing >150 MIA and control offspring revealed that MIA offspring could be stratified into distinct subgroups that were characterized by the presence or absence of multiple behavioral dysfunctions. The two subgroups also differed in terms of their transcriptional profiles in cortical and subcortical brain regio…

The Microbiota-Gut-Brain axis (MGBA) is a bidirectional communication pathway between gut bacteria and the central nervous system (CNS) (including the intestine) that exerts a profound influence on neural development, neuroinflammation, activation of stress response and neurotransmission, in addition to modulating complex behaviours, such as sociability and anxiety. Several MGBA modulating approaches are possible, such as probiotic administration. A reasonable pharmacological approach would also be the contemporarily administration of both prebiotics and postbiotics. To test this hypothesis, we probed the effects of α-lactalbumin (ALAC; a prebiotic in the dose range of 125-500 mg/kg) and sodium butyrate (NaB; a postbiotic in the dose range of 30-300 mg/kg) alone and in combination.
