ABSTRACTHere we characterized the Social versus Food Preference Test, a behavioral paradigm designed to investigate the competition between the choice to seek social interaction versus the choice to seek food. We assessed how this competition was modulated by internal cues (social isolation, food deprivation), external cues (time-of-testing, stimulus salience), sex (males, females), age (adolescents, adults), and rodent model (Wistar rats, C57BL/6J mice). We found that changes in stimulus preference in response to the internal and external cue manipulations were similar across cohorts. Specifically, social over food preference scores were reduced by food deprivation and social familiarly in Wistar rats and C57BL/6J mice of both sexes. Interestingly, the degree of food deprivation-induced changes in stimulus investigation patterns were greater in adolescents compared to adults in Wistar rats and C57BL/6J mice. Strikingly, baseline stimulus preference and investigation times varied greatly between rodent models: across manipulations, Wistar rats were generally more social-preferring and C57BL/6J mice were generally more food-preferring. Adolescent Wistar rats spent more time investigating the social and food stimuli than adult Wistar rats, while adolescent and adult C57BL/6J mice investigated the stimuli a similar amount. Neither social isolation nor time-of-testing altered behavior in the Social versus Food Preference Test. Together, our results indicate that the Social versus Food Preference Test is a flexible behavioral paradigm suitable for future interrogations of the peripheral and central systems that can coordinate the expression of stimulus preference related to multiple motivated behaviors.HIGHLIGHTSRats prefer social over food when sated, and this is attenuated by food deprivation.Mice have no preference when sated, and prefer food over social when food-deprived.Rats prefer a familiar social stimulus or a novel social stimulus over food.Mice prefer food over a familiar social stimulus.Adolescent rats investigate social and food stimuli longer than adult rats.GRAPHICAL ABSTRACT

In the social transmission of food preference paradigm, naive observer rats acquire safety information about novel food sources in the environment through social interaction with a demonstrator rat that has recently eaten said food. Research into the behavioural mechanisms governing this form of learning has found that observers show increased reliance on socially acquired information when the state of the environment makes personal examination of their surroundings risky. We aimed to (1) determine whether reliance on social information would decrease if previous reliance on social learning was unsuccessful, and (2) whether reliance on the specific demonstrator that had transmitted poor information would similarly decrease. By inducing illness in observers following consumption of a socially demonstrated food, we created an environmental situation in which reliance on socially acquired information was maladaptive. We found that under these conditions, observers showed no change in their reliance on a specific demonstrator or socially learned information in general. Our experiment also unexpectedly produced results showing that recent demonstrators were more influential in later transmissions than demonstrators that had been learned from less recently. Notably, this effect only emerged when the observer simultaneously interacted with both demonstrators, indicating that demonstrators must be in direct competition for this effect to manifest.

Abstract Behavior is influenced by a combination of factors, with the expression of the appropriate behavior dependent on an individual’s current motivational state and the presence of stimuli in their surrounding environment. Thus far, most laboratory studies have focused on uncovering the peripheral and central systems that regulate the expression of a single behavior or the expression of a suite of behaviors associated with a single motivational state. In natural settings, however, an individual can be simultaneously experiencing multiple motivational states with multiple choices of how to act. Yet, the direct assessment of the roles of peripheral and central systems in coordinating motivated behavioral choice is largely understudied. This may be due to a lack of behavioral tests that are suitable for such investigations. Here, we describe a recently developed behavioral paradigm, hereafter called the Social versus Food Preference Test. This behavioral paradigm was validated in both rats and mice and is highly flexible, which will allow addressing of a wide range of research questions concerning the peripheral and central systems that coordinate the choice to seek social interaction versus the choice to seek food.

This paper explores the charitable work of Buddhist women who work as petty traders in Hồ Chí Minh City. By focusing on the social interaction between givers and recipients, it examines the traders’ class identity, their perception of social stratification, and their relationship with the state. Charitable work reveals the petty traders’ negotiations with the state and with other social groups to define their moral and social status in Vietnam’s society. These negotiations contribute to their self-identification as a moral social class and to their perception of trade as ethical labor.

У  статті  висвітлено  методологічні  та  практичні  засади  вивчення  онтогенезу  соціального  інтелекту. Складність вивчення даного соціально-психологічного феномену пов’язана із дотичністю його  до багатьох явищ, які описують умови успішності соціальної взаємодії особистості. Проаналізовано наявні  теоретичні   підходи   до   визначення   змісту   та   структури  соціального  інтелекту,   до   взаємозв’язку  останнього  з  іншими  видами  інтелекту.  Визначено,  що  дослідження  соціального  інтелекту  молодших  школярів слід здійснювати на основі розуміння останнього як здатності, що виникає на базі комплексу  інтелектуальних,   особистісних,   комунікативних   і   поведінкових   рис,   що   зумовлюють   прогнозування  розвитку  міжособистісних  ситуацій,  інтерпретацію  інформації  і  поведінки,  готовність  до  соціальної  взаємодії і прийняття рішень. Здійснене пілотажне емпіричне дослідження прогностичних можливостей  дітей  молодшого  шкільного  віку  продемонструвало  наявні  позитивні  кореляційні  зв’язки  між  рівнем  розвитку здатності до передбачення найбільш адекватного сценарію розвитку подій у соціальній ситуації  та рівнем розвитку мовленнєвого досвіду. Найбільш тісний взаємозв’язок виявлено між рівнем розвитку  здатності  передбачати  адекватну  вербальну  відповідь  у  ситуації  комунікації  та  рівнем  розвитку  мовленнєвої компетентності та мовленнєвої діяльності дітей молодшого шкільного віку. Таким чином,  були зроблені попередні висновки про наявність взаємозв’язку між мовленнєвим досвідом та прогностичним  можливостями у складі соціального інтелекту дитини молодшого шкільного віку The  article  outlines  the  methodological  and  practical  principles  of  studying  the  ontogenesis  of  social  intelligence. The complexity of studying this socio-psychological phenomenon is associated with its attractiveness to  many  phenomena  that  describe  the  conditions  for  the  successful  social  interaction.  The  existing  theoretical  approaches to the definition of the content and structure of social intelligence, to the interrelationship of it with  other types of intelligence are analyzed. It is determined that research of social intelligence of junior pupils should  be carried out on the basis of the understanding of this kind of intelligencer as an ability that based on a complex of  intellectual, personal, communicative and behavioral features. This complex predetermines the forecasting of the  development  of  interpersonal  situations,  the  interpretation  of  information  and  behavior,  readiness  for  social  interaction  and  decision-making.  The  research  of  the  prognostic  possibilities  of  primary  school  children  demonstrated the positive correlation between the level of development of the ability to predict the most adequate  scenario of the development of events in the social situation and the level of development of speech experience. The  closest relationship is found between the level of development of the ability to provide an adequate verbal response  in the context of communication and the level of development of speech competence and speech activity of children  of junior school age. Thus, was done a conclusion about the existence of a relationship between speech experience  and prognostic possibilities in the social intellect of a child of junior school age.
