Contingency awareness,partial reinforcement effects,and curiosity motivation in children

Third- and fourth-grade children were given a two-choice discrimination learning task, designed to associate each of three syllables with a different reward schedule: 100% reward, 50% reward, and 0% reward. Subsequent to the conditioning phase, measures were made of the subject's awareness of the reward contingencies associated with the syllables, as well as the pleasantness and curiosity which these syllables had acquired during the conditioning. The results showed that a partially rewarded cue was evaluated as somewhat less “pleasant” than a continuously rewarded cue, but evoked more “curiosity” than either the continuous or nonrewarded cues. These effects emerged only for the contingency aware groups.     

Reasons as Premises of Good Reasoning

Many philosophers have been attracted to the view that reasons are premises of good reasoning – that reasons to φ are premises of good reasoning towards φ‐ing. However, while this reasoning view is indeed attractive, it faces a problem accommodating outweighed reasons. In this article, I argue that the standard solution to this problem is unsuccessful and propose an alternative, which draws on the idea that good patterns of reasoning can be defeasible. I conclude by drawing out implications for the debate over pragmatic reasons for belief and other attitudes and for one influential form of reductionism about the normative.     

The Relationship Between Perceived Violation of Social Norms and Social Control: Situational Factors Influencing the Reaction to Deviance

Social control is the generic term for all reactions through which people express their disapproval to someone who engages in a counternormative behavior or who holds a counter-normative attitude. The literature on helping behavior suggests that perceived personal implication should play an important role in the decision of whether or not to exert social control. A field study involving 5 different experimental settings was conducted in order to test this hypothesis. Confederates engaged in a variety of behaviors that violated social norms. Perceived personal implication was consistently the best predictor of social control behavior, such that the more someone felt that a deviant behavior affected him or her personally, the more he or she was likely to communicate his or her disapproval to the deviant confederate. Perceived deviance of the behavior was a less powerful predictor of social control. These findings speak to the moderating factors of social control behavior and to the circumstances under which social norms protecting public property are likely to be perpetuated.     

Self‐Efficacy,Self‐Rated Abilities,Adjustment, and Academic Performance

This study examined the association between self‐efficacy and self‐rated abilities in conjunction with adjustment and academic performance with a diverse sample of 271 undergraduate college students with majors in the liberal arts. Significant positive associations between and among the constructs in different combinations were found. The discussion focuses on the theoretical and practice implications of the results and offers suggestions for further research.     

The association between infants' self-regulatory behavior and MAOA gene polymorphism

Self-regulatory behavior in early childhood is an important characteristic that has considerable implications for the development of adaptive and maladaptive functioning. The present study investigated the relations between a functional polymorphism in the upstream region of monoamine oxidase A gene (MAOA) and self-regulatory behavior in a sample of Chinese infants at 6 months of age. Self-regulation was assessed by observing infants' behavior of orienting visual attention away from a threatening event in the laboratory situation. The results indicated that regulatory behavior was associated with the functional MAOA gene polymorphism in girls, but not boys. Girls with 4/4 genotypes displayed significantly higher regulation than girls with 3/3 and 3/4 genotypes. The present study provided evidence for gender differences on the role of MAOA gene polymorphism in socioemotional functioning in the early years.     

Spatial reasoning in Tenejapan Mayans

Language communities differ in their stock of reference frames (coordinate systems for specifying locations and directions). English typically uses egocentrically-defined axes (e.g., “left–right”), especially when describing small-scale relationships. Other languages such as Tseltal Mayan prefer to use geocentrically-defined axes (e.g., “north–south”) and do not use any type of projective body-defined axes. It has been argued that the availability of specific frames of reference in language determines the availability or salience of the corresponding spatial concepts. In four experiments, we explored this hypothesis by testing Tseltal speakers’ spatial reasoning skills. Whereas most prior tasks in this domain were open-ended (allowing several correct solutions), the present tasks required a unique solution that favored adopting a frame-of-reference that was either congruent or incongruent with what is habitually lexicalized in the participants’ language. In these tasks, Tseltal speakers easily solved the language-incongruent problems, and performance was generally more robust for these than for the language-congruent problems that favored geocentrically-defined coordinates. We suggest that listeners’ probabilistic inferences when instruction is open to more than one interpretation account for why there are greater cross-linguistic differences in the solutions to open-ended spatial problems than to less ambiguous ones.     

A Genetics Primer for Social Health Research

The recently completed sequencing of the human genome heralds a new era in the study of social influences upon health. Because the interactions between genes and the environment are bidirectional, expertise in the areas of psychosocial processes and health behaviors will be necessary for elucidating how genes, behavior, and the environment interact to affect health outcomes. For investigators whose primary background is in social health research, the terminology used by geneticists may seem like a foreign language. To help navigate this foreign territory, the nature of genetic variation and gene action is presented in non‐technical terms using the serotonin transporter gene as an example because it is thought to influence sensitivity to the social environment. In addition, we describe several methodological pitfalls to be avoided when associating genetic variation with psychosocial and behavioral risk factors for poor health outcomes.     

Substance Use and Health and Safety among Homeless Youth

This study examines how substance use is associated with the health and safety of homeless youth using cross-sectional, self-report data from 285 homeless adolescents. Path models were used to examine concurrent relationships between youth’s substance use and multiple aspects of their health and safety, including measures of psychological distress, housing risk and instability, and medical problems. Substance use was examined with both global (i.e., a composite of days of use across various drugs and alcohol) and specific (i.e., rates of use of specific drugs, injection drug use) measures. After controlling for demographic and historical variables, number of days of use was significantly related to psychological distress, whereas injection drug use was significantly related to housing risk. Examination of specific drugs revealed relationships between psychological distress and the use of alcohol, cocaine, and amphetamines, and a specific relationship between housing risk and the use of heroin. None of the measures of substance use was significantly related to youth’s medical problems. Implications for interventions with homeless adolescents are discussed.     

The "model minority" and their discontent: examining peer discrimination and harassment of Chinese American immigrant youth

Using an ecological framework, the authors explore the reasons for peer discrimination and harassment reported by many Chinese American youth. They draw on longitudinal data collected on 120 first- and second-generation Chinese American students from two studies conducted in Boston and New York. Our analyses suggested that reasons for these experiences of harassment lay with the beliefs about academic ability, the students' immigrant status and language barriers, within-group conflicts, and their physical appearance that made them different from other ethnic minority or majority students. Implications and future research are also discussed.     

From peers to policy: how broader social contexts influence the adaptation of children and youth in immigrant families

This chapter provides an overview of non family contexts that shape the development and adjustment of children and youth from immigrant families. It also describes the four chapters in this special issue that focus on peer, network, legal, and institutional contexts that influence the lives of immigrant parents and their children. Directions for future research on the social contexts of development in immigrant families are discussed.
