Operant conditioning in redwinged blackbirds

An operant conditioning technique for use with passerine birds is described. Two redwinged blackbirds were successfully conditioned to perch-hop for food reinforcement. Continuous reinforcement and fixed-ratio schedules involving substantial ratio requirements were used to maintain this response. The behavior of the two redwinged blackbirds was comparable to that of more conventional organisms working on similar schedules of reinforcement.     

Cain. The separation of shame and guilt exemplified in Genesis

Referring to Cain's fratricide, the authors investigate the origin of guilt. They assume that feelings of shame preceded feelings of guilt and that the former are the cause of the destructiveness and persistence of the latter.     

Folk theory of social change

People have a folk theory of social change (FTSC). A typical Western FTSC stipulates that as a society becomes more industrialized, it undergoes a natural course of social change, in which a communal society marked by communal relationships becomes a qualitatively different, agentic society where market‐based exchange relationships prevail. People use this folk theory to predict a society's future and estimate its past, to understand contemporary cross‐cultural differences, and to make decisions about social policies. Nonetheless, the FTSC is not particularly consistent with the existing cross‐cultural research on industrialization and cultural differences, and needs to be examined carefully.     

Continuous and discontinuous drawing: high temporal variability exists only in discontinuous circling in young children

The authors studied whether the drawing variability in young children is best explicable by (a) demands on the explicit timing system, (b) an underdeveloped ability to control limb dynamics, or (c) both. The explicit timing demands were lower in continuous drawing in comparison with the discontinuous task. The authors manipulated limb dynamics by changing the number of joints involved, with line drawing requiring fewer joints than circle drawing. Results showed that young children had high temporal variability in discontinuous circling but not in other conditions. The authors argue that both explicit timing and dynamic complexity of limb control may be determinants of temporal consistency and may thus play an important role in the development of drawing and writing skills in children.     

The what,how, and why of moralization: A review of current definitions,methods, and evidence in moralization research

Moralization has major social and political implications. Although there is a depth of research on the nature and implications of moral attitudes and moral convictions, there has been less of a focus on the psychological processes by which actions, attitudes, or entities become moralized, or move from lesser to greater moral significance, and the research that does exist is highly fragmented. In the present paper, we provide a two‐factor structure for understanding the current state of research on moralization, categorizing extant moralization research by (1) whether it examines judgments of actions, attitudes, or entities and (2) whether it captures moral recognition (the shift from neutral to moral), or moral amplification. Using this framework, we then consider the various routes through which moralization may occur, discuss emerging research on the influence that social norms can have on this process, and address future areas of research. Overall, we hope to provide some initial steps toward developing a more integrated framework for understanding moralization.     

Poor emotion regulation ability mediates the link between depressive symptoms and affective bipolarity

People's relationship between positive and negative affect varies on a continuum from relatively independent to bipolar opposites, with stronger bipolar opposition being termed affective bipolarity. Experiencing more depressive symptoms is associated with increased bipolarity, but the processes underlying this relation are not yet understood. Here, we sought to replicate this link, and to examine the role of two potential mediating mechanisms: emotion regulation ability, and trait brooding. Drawing from the Dynamic Model of Affect, we hypothesised that (a) a poor ability to regulate negative emotion, and (b) the tendency to brood over one's depressed feelings would predict stronger affective bipolarity, and mediate the relationship between depressive symptoms and affective bipolarity. To measure affective bipolarity, we calculated within-person affect correlations using two weeks of experience sampling data from a community sample (n?=?100). Mediation analyses indicated that baseline assessments of an inability to regulate negative emotions in general, but not brooding specifically, mediated the relation between depressive symptoms and affective bipolarity. These findings highlight an initial mechanism through which depressive symptoms are associated with lower emotional complexity and flexibility.     

Psychological essentialism and attention allocation: preferences for stereotype-consistent versus stereotype-inconsistent information

People who believe that human attributes are immutable (entity theorists) display preferences for stereotype-consistent over stereotype-inconsistent information (J. E. Plaks, S. J. Stroessner, C. S. Dweck, & J. W. Sherman, 2001). In this article, the authors argue that entity theories are components of broader sets of beliefs that represent differences between people in terms of underlying essences. Consistent with expectations, the authors found that measures of essentialist beliefs (i.e., in the biological basis, discreteness, informativeness, and inherence of human attributes) covaried with the presence of entity theories. Essentialist beliefs as a set were related to stronger preferences for stereotype-consistent information, and this effect was not reducible to the effect of entity theories. The authors propose that research on implicit person theories can be placed within an encompassing framework of psychological essentialism.     

The relationships between perfectionism,religious motivation,and mental health utilisation among latter-day saint students

The present study examined the influence of perfectionism and religious motivation on help-seeking and attitudes towards mental health services (ATMHS) in a Latter-Day Saint sample of 119 undergraduates. Increased levels of perfectionism significantly predicted more negative ATMHS. Higher intrinsic religious motivation was significantly and positively related to help-seeking from religious sources, but not from mental health professionals. Intrinsic religious motivation was also related to perfectionism, but only for adaptive subscales. The implications for focusing utilisation interventions towards religious populations are discussed.     

Effects and mechanisms of working memory training: a review

Can cognitive abilities such as reasoning be improved through working memory training? This question is still highly controversial, with prior studies providing contradictory findings. The lack of theory-driven, systematic approaches and (occasionally serious) methodological shortcomings complicates this debate even more. This review suggests two general mechanisms mediating transfer effects that are (or are not) observed after working memory training: enhanced working memory capacity, enabling people to hold more items in working memory than before training, or enhanced efficiency using the working memory capacity available (e.g., using chunking strategies to remember more items correctly). We then highlight multiple factors that could influence these mechanisms of transfer and thus the success of training interventions. These factors include (1) the nature of the training regime (i.e., intensity, duration, and adaptivity of the training tasks) and, with it, the magnitude of improvements during training, and (2) individual differences in age, cognitive abilities, biological factors, and motivational and personality factors. Finally, we summarize the findings revealed by existing training studies for each of these factors, and thereby present a roadmap for accumulating further empirical evidence regarding the efficacy of working memory training in a systematic way.
