Further evidence for the role of inferential reasoning in forward blocking

Previous studies on human causal learning (De Houwer & Beckers, 2003; De Houwer, Beckers, & Glautier, 2002) showed that secondary task difficulty (performing an easy vs. a difficult secondary task during the main causal learning task) and ceiling information (outcome occurs with a maximal vs. submaximal intensity) had an influence on forward blocking (i.e., lower causal ratings for cue T when AT+ trials are preceded by A+ trials than when no A+ trials are presented). We extended these studies by also examining self-reports of participants about the reasons behind their causal ratings. Blocking was found only for participants who reported an appropriate blocking inference. Furthermore, secondary task difficulty and ceiling information influenced the number of participants who reported an appropriate blocking inference. These findings point to a major impact of inferential reasoning in human causal learning.     

Moral outrage mediates the dampening effect of system justification on support for redistributive social policies

To understand how and why people tolerate ongoing social and economic inequality, we conducted two studies investigating the hypothesis that system justification is associated with reduced emotional distress and a lack of support for helping the disadvantaged. In Study 1, we found that the endorsement of a system-justifying ideology was negatively associated with moral outrage, existential guilt, and support for helping the disadvantaged. In Study 2, the induction of a system-justification mind-set through exposure to "rags-to-riches" narratives decreased moral outrage, negative affect, and therefore intentions to help the disadvantaged. In both studies, moral outrage (outward-focused distress) was found to mediate the dampening effect of system justification on support for redistribution, whereas existential guilt (Study 1) or negative affect in general (Study 2; inward-focused distress) did not. Thus, system-justifying ideology appears to undercut the redistribution of social and economic resources by alleviating moral outrage.     

The making of an analyst: from 'ideal' to 'good-enough'

This paper addresses the issue of variances in training modalities and how this is linked to one's personal experience of training and to one's analytic lineage. The author, who bases his reflections on discussions held during the yearly directors of training meeting of the North American Jungian Societies, suggests that, while each institute aims to provide an 'ideal' training programme for its candidates, the philosophy underlying how this ideal is defined depends, in large part, on the theoretical and philosophical orientation of the founding fathers and mothers. This results in a form of analytic lineage that necessarily impacts on the form and content of the 'ideal' programme. Shadow issues related to analytic lineage in the admissions procedures, case consultation, exam committees and review committees are presented. Motivation for why we choose to train and reflections on what makes an analyst 'Jungian' are explored.     

Stress during puberty boosts metabolic activation associated with fear-extinction learning in hippocampus, basal amygdala and cingulate cortex

Adolescence is characterized by major developmental changes that may render the individual vulnerable to stress and the development of psychopathologies in a sex-specific manner. Earlier we reported lower anxiety-like behavior and higher risk-taking and novelty seeking in rats previously exposed to peri-pubertal stress. Here we studied whether peri-pubertal stress affected the acquisition and extinction of fear memories and/or the associated functional engagement of various brain regions, as assessed with 2-deoxyglucose. We showed that while peri-pubertal stress reduced freezing during the acquisition of fear memories (training) in both sexes, it had a sex-specific effect on extinction of these memories. Moreover hippocampus, basal amygdala and cingulate and motor cortices showed higher metabolic rates during extinction in rats exposed to peri-pubertal stress. Interestingly, activation of the infralimbic cortex was negatively correlated with freezing during extinction only in control males, while only males stressed during puberty showed a significant correlation between behavior during extinction and metabolic activation of hippocampus, amygdala and paraventricular nucleus. No correlations between brain activation and behavior during extinction were observed in females (control or stress). These results indicate that exposure to peri-pubertal stress affects behavior and brain metabolism when the individual is exposed to an additional stressful challenge. Some of these effects are sex-specific.     

Development of adolescents' peer crowd identification in relation to changes in problem behaviors

This 5-wave longitudinal study, which included 1,313 Dutch adolescents, examined the development of peer crowd identification in relation to changes in problem behaviors. Adolescents from 2 age cohorts annually reported their identification with 7 peer crowds and their levels of internalizing and externalizing problem behaviors. Univariate latent growth curve analyses revealed declines (i.e., "Hip Hoppers" and "Metal Heads") or declines followed by stabilization (i.e., "Nonconformists") in identification with nonconventional crowds and increases (i.e., "Elites" and "Brains") or declines followed by stabilization (i.e., "Normals" and "Jocks") in identification with conventional crowds. Multivariate latent growth curve analyses indicated that stronger and more persistent identifications with nonconventional crowds were generally associated with more problem behaviors throughout adolescence. In contrast, stronger and more persistent identifications with conventional crowds were generally associated with fewer problem behaviors throughout adolescence with the notable exception of Brains, who showed a mixed pattern. Though characterized by fewer externalizing problems, this group did report more anxiety problems. These findings and their implications are discussed.     

Decay uncovered in nonverbal short-term memory

Decay theory posits that memory traces gradually fade away over the passage of time unless they are actively rehearsed. Much recent work exploring verbal short-term memory has challenged this theory, but there does appear to be evidence for trace decay in nonverbal auditory short-term memory. Numerous discrimination studies have reported a performance decline as the interval separating two tones is increased, consistent with a decay process. However, most of this tone comparison research can be explained in other ways, without reference to decay, and these alternative accounts were tested in the present study. In Experiment 1, signals were employed toward the end of extended retention intervals to ensure that listeners were alert to the presence and frequency content of the memoranda. In Experiment 2, a mask stimulus was employed in an attempt to distinguish between a highly detailed sensory trace and a longer-lasting short-term memory, and the distinctiveness of the stimuli was varied. Despite these precautions, slow-acting trace decay was observed. It therefore appears that the mere passage of time can lead to forgetting in some forms of short-term memory.     

Early Childhood Care Trends and Associations with Child Health Well-being in China: Evidence from the CHNS 1991 to 2011 Data

It has become increasingly common for young children to be taken care of by multiple caregivers in China after the socio-economic reforms. Complex migration patterns and high female labour force participation have led to children receiving care from various individuals in different contexts. However, little is known about how childcare arrangements are associated with child health well-being. This study examines various early childhood caregivers and their influences on children’s physical health in China. Using data from the China Health and Nutrition Survey (CHNS 1991–2011) with 3,470 children aged 2 to 6, we first identified different types of childcare arrangements in and outside of the household based on who provides the care, where they provide the care, and the intensity of the care. Then we examined the relationship between various childcare arrangements and health outcomes for children. Overall, household members undertook early childhood care tasks in China, with an increase in grandparents as primary caregivers between 1991 and 2011. The proportion of children receiving formal childcare fluctuated around 20% during this period. The findings suggest that: 1) primary caregiver in the household other than parents is not associated with undesirable physical health outcomes; 2) formal childcare outside the household is associated with higher height and lower BMI scores; 3) primary caregivers in the household, particular grandparents, moderate the association between childcare arrangements outside the household and children’s health outcomes. It yields an implication that early childhood care policies incorporating multiple caregivers would benefit children’s well-being in China.

     

French Philosophy of Science,Structuralist Epistemology,and the Problem of the Subject

This article examines the multiple relations between the rationalist tradition of French philosophy of science exemplified by the work of Gaston Bachelard, and the rethinking of the relation between science and ideology undertaken by Louis Althusser and a young Alain Badiou in the 1960s. Both Bachelard and Althusser are interrogated for the philosophy of language that underpins their respective visions of scientificity; in turn, the problem of the subject is posed, in part through an investigation of Althusser's inheritance and transformation of Lacanian psychoanalysis.
