不公平感及相关决策的认知神经机制

公平是人类社会生活的基本规范之一,不公平感及其相关决策则是研究者们关注的重要课题。长期以来,该领域的研究一般采用最后通牒博弈或其变式展开。大量脑成像研究探查了关于不公平感及相关决策的认知神经机制,尤其集中探讨了最后通牒博弈的回应者对不公平提议进行反应的脑区及其对应功能。经常得到关注的脑区包括了前脑岛、前扣带皮层、背外侧前额叶、内侧前额叶、杏仁核和颞顶交界等。对特殊人群的不公平感及相关决策进行研究可以帮助检验或澄清上述重要脑区及脑网络在不公平感及相关决策中扮演的角色,同时也阐释特殊人群的社会认知功能的特点。近年来,相当数量的研究关注了不同情境因素(包括分配方案相关因素和社会情境相关因素)调制不公平感及相关决策的过程,并讨论其背后的认知神经机制。未来的研究更应利用多模态数据分析方法,同时结合基因和激素层面的研究,以期深入对不公平感及相关决策的心理和生理机制的理解。     

The influence of environmental context in interpersonal observation–execution

Cyclical upper-limb movements involuntarily deviate from a primary movement direction when the actor concurrently observes incongruent biological motion. We examined whether environmental context influences such motor interference during interpersonal observation–execution. Participants executed continuous horizontal arm movements while observing congruent horizontal or incongruent curvilinear biological movements with or without the presence of an object positioned as an obstacle or distractor. When participants were observing a curvilinear movement, an object located within the movement space became an obstacle, and, thus, the curvilinear trajectory was essential to reach into horizontal space. When acting as a distractor, or with no object, the curvilinear trajectory was no longer essential. For observing horizontal movements, objects were located at the same relative locations as in the curvilinear movement condition. We found greater involuntary movement deviation when observing curvilinear than horizontal movements. Also, there was an influence of context only when observing horizontal movements, with greater deviation exhibited in the presence of a large obstacle. These findings suggest that the influence of environmental context is underpinned by the (mis-)matching of observed and executed actions as incongruent biological motion is primarily coded via bottom-up sensorimotor processes, whilst the congruent condition incorporates surrounding environmental features to modulate the bottom-up sensorimotor processes.     

Effects of pictorial context reinstatement on correct and false recognition memory: insights from the simplified conjoint recognition paradigm

We used the Fuzzy-Trace Theory (FTT) perspective to investigate the role of context switching or reinstatement on correct and false recognition in Deese–Roediger–McDermott (DRM) and simple false memory for occurrence (FMO) tasks. In two experiments, participants studied words presented against unique picture backgrounds. The results indicated that providing specific item-context associative information in the reinstated-context test condition enhances verbatim trace retrieval of targets but does not influence their gist retrieval. In the case of false recognitions of related distracters, manipulations of retrieval context resulted in different effects across experiments, putatively because the DRM and FMO tasks involve different latent-processes implied by FTT. The results confirmed the critical role of retrieval conditions for false and correct recognition memory and showed the insights that can be gained from the process-level multinomial modelling analyses of data obtained in particular experimental paradigms.     

语境位置对不同认知方式个体歧义句歧义消解的影响

采用意义适合性判断任务,考察了语境位置对不同认知方式个体歧义句理解过程中抑制内部干扰的影响。结果发现：语境位置影响歧义句的歧义消解,对歧义句不适当意义的抑制作用方面,前语境优于后语境;在自然阅读的条件下,在句子加工的初始阶段,场独立个体能够更好的利用前语境信息抑制内部无关信息的干扰,而场依存个体在句子加工的初始阶段对前、后语境的阅读时间上不存在差异,而在句子加工的后期需用更多时间才能完成对内部干扰的抑制。     

Interactive context integration in children? Evidence from an action memory study

Action–object phrases (e.g., “lift the bottle”) are remembered better if they have been enacted rather than learned verbally. This enactment effect is largest in free recall for phrases with objects (e.g., “bottle”) present because these phrases can be interactively encoded with those context objects (interactive context integration) that serve as retrieval cues. The current study investigated whether 6- and 8-year-olds are already capable of interactive context integration. Experiment 1 demonstrated interactive context integration with 8-year-olds. This was hindered in a condition where attention was directed away from context objects. Experiment 2 demonstrated interactive context integration with 6-year-old kindergartners. Taken together, our findings show that even 6-year-olds are capable of incidental context integration through enactment and that this process is attention based.     

Teacher performance goal practices and elementary students' behavioral engagement: a developmental perspective

We investigated growth trajectories for classroom performance goal practices and for student behavioral engagement across grades 2 to 5 for 497 academically at-risk elementary students. This study is the first longitudinal investigation of performance goal practices in the early elementary years. On average, teacher use of performance goal practices increased and students' behavioral engagement declined across the four years. Using autoregressive latent trajectory (ALT) models, we examined the synchronous relations between teacher-reported performance goal practices and teacher-reported student behavioral engagement. As expected, as students move into classrooms with a new teacher with less emphasis on performance goal practices, they become more behaviorally engaged in school. Gender did not moderate these results. Implications for teacher professional development are discussed.     

From the Macro to the Micro: A Geographic Examination of the Community Context and Early Adolescent Problem Behaviors

This study examined how multiple dimensions and levels of the community context associated with early adolescent problem behaviors in rural communities. Four thousand, five hundred and nine eighth-grade students in 28 rural and small town school districts in two states participated in surveys regarding substance use and delinquency in 2005. Locations of alcohol retailers, tobacco retailers, youth-serving organizations, and student residences were geocoded. Associations of the number of proximal alcohol and tobacco retailers, and youth-serving organizations with an early-adolescent problem behavior index were tested in Nonlinear Mixed Models that controlled for multiple district-level and individual characteristics. Multi-level model results demonstrated that the number of alcohol and tobacco retail locations within a one-mile radius of each adolescent's home positively associated with student-reported problem behaviors above and beyond the influence of school district and individual characteristics. Results suggest that the proximal community context added significantly to the district context when understanding the occurrence of early adolescent problem behaviors. Recognizing this variability in geographically determined risk within a community will likely enhance the effectiveness of community prevention activities.     

Revealing the invisible hand: The role of teachers in children's peer experiences

To introduce this special issue, the concept of the teacher as an “invisible hand” is presented as a metaphor to describe the potentially influential but relatively understudied contribution that educators are likely to have on children’s peer relationships and their broader interpersonal growth. Building from conceptual work distinguishing between the role of adults and peers in children’s social development, we summarize empirical support for the view that teachers are in a position to develop and guide the classroom as a society by simultaneously directing institutional expectations while also providing students with opportunities to collectively construct their own peer culture. Key social development constructs are reviewed from this lens, and the four articles and two commentaries that constitute this special issue are discussed in relation to their contributions to clarifying and extending current views of the role of teachers in school social dynamics. We conclude by considering intervention implications of this work, and we argue that teachers are the one professional in a child’s life who have the opportunity to view the whole child in relation to the social ecology in which he or she is embedded.     

Patterns in parent–child conversations about animals at a marine science center

Parent-child conversations are a potential source of children's developing understanding of the biological domain. We investigated patterns in parent-child conversations that may inform children about biological domain boundaries. At a marine science center exhibit, we compared parent-child talk about typical sea animals with faces (fish) with talk about atypical sea animals without faces (e.g., sea stars), in particular with respect to anthropomorphic talk and use of animate pronouns. Parents talked about psychological states and used animate pronouns more often for typical than atypical animals; children showed a similar pattern for pronouns but did not differ in their property talk between typical and atypical animals. It was clearly parents who initiated the use of psychological properties and animate pronouns for typical animals. These patterns suggest that parent-child conversations draw boundaries between typical and atypical animals and could support children's inclination to anthropomorphize.     

Educational privilege: The role of school context in the development just world beliefs among Brazilian adolescents

The purpose of this study is to understand the development of Brazilian adolescents' justice perceptions across different contexts of educational privilege. Past research has found that, in adolescence, the belief in a just world (BJW) differentiates between personal and general and declines. However, prior research has not included adolescents from various socioeconomic statuses, samples in Latin America, or focused on the role of the educational context on the developmental trajectory. Participants were 385 adolescents from 3 schools (private, public and military) in Southern Brazil between 9th and 11th grade. Students completed the personal and general BJW survey. Results revealed a significant interaction of school and grade level of adolescents' personal BJW. Contrary to previous research, personal and general BJW was not always lower in higher grades. Among privileged educational contexts, data indicated that personal BJW may even increase, with the decrease notable in the lower resourced school. In contrast, general BJW was relatively consistent across all Brazilian adolescents. Results provide important insight into the role that privilege and education play across adolescents' development of BJW. This research questions the generalizability of previous studies on the development of BJW and indicates that the trajectory may be dependent upon educational and cultural context.
