Effects of Parenting and Deviant Peers on Early to Mid-Adolescent Conduct Problems

We investigated the influence of effective parenting behaviors (father and mother reports) and deviant peer association (adolescent reports) on subsequent young adolescent conduct problems (teacher reports) during grades 7–9, using structural equation modeling. Data were from a sample of 226 rural adolescents (n?=?112 boys; n?=?107 girls; n?=?7 gender unknown), their parents, and teachers. Both effective parenting and association with deviant peers influenced later conduct problems; however, the pattern of influence varied across time and between fathers and mothers, with complex patterns of interactions between effective parenting and peer deviance. From seventh to eighth grade, effective parenting by both mothers and fathers buffered the effect of higher levels of peer deviance on conduct problems across adolescent gender. From eighth to ninth grade (i.e., transition into high school), fathers’ effective parenting buffered the effects of deviant peer association on their daughters’ conduct problems, whereas both fathers’ and mothers’ influence was stronger for sons when deviant peer associations were lower. Analyses also evaluated bi-directional longitudinal effects among adolescents, parents, and peers. Although varying by parent and adolescent gender or adolescent age, results generally supported the protective effects of parenting on their children’s conduct problems during early to mid adolescence.     

Reliving emotional personal memories: affective biases linked to personality and sex-related differences

Although available evidence suggests that the emotional valence and recollective properties of autobiographical memories (AMs) may be influenced by personality- and sex-related differences, overall these relationships remain poorly understood. The present study investigated these issues by comparing the effect of general personality traits (extraversion and neuroticism) and specific traits linked to emotion regulation (ER) strategies (reappraisal and suppression) on the retrieval of emotional AMs and on the associated postretrieval emotional states, in men and women. First, extraversion predicted recollection of positive AMs in both men and women, whereas neuroticism predicted the proportion of negative AMs in men and the frequency of rehearsing negative AMs in women. Second, reappraisal predicted positive AMs in men, and suppression predicted negative AMs in women. Third, while reliving of positive memories had an overall indirect effect on postretrieval positive mood through extraversion, reliving of negative AMs had a direct effect on postretrieval negative mood, which was linked to inefficient engagement of suppression in women. Our findings suggest that personality traits associated with positive affect predict recollection of positive AMs and maintenance of a positive mood, whereas personality traits associated with negative affect, along with differential engagement of habitual ER strategies in men and women, predict sex-related differences in the recollection and experiencing of negative AMs. These findings provide insight into the factors that influence affective biases in reliving AMs, and into their possible link to sex-related differences in the susceptibility to affective disorders.     

Modelling Beyond Application: Epistemic and Non-epistemic Values in Modern Science

In recent years, philosophers of science have begun to realize that the clear separation of the creation of models in academia and the application of models outside science is not possible. When these philosophers address hybrid contexts in which science is entwined with policy, business, and other realms of society, these often practically oriented realms no longer represent ‘the surroundings’ of science but rather are considered an essential part of it. I argue—and demonstrate empirically—that the judgement of a theory or model conducted by scientists in such hybrid contexts may contain two parts: one is truth supportive and the other is utility oriented. In relation to the debate on science and values, the article seeks to reinforce the argument in modern philosophy of science that the boundaries between epistemic and non-epistemic values are blurred. The article stresses that non-epistemic values may be also understood as values that contribute to the instrumental success of a theory or model and—in this way—influence scientific practice in the hybrid contexts.     

Basal ganglia engagement during feedback processing after a substantial delay

The striatum has been shown to play an important role in learning from performance-related feedback that is presented shortly after each response. However, less is known about the neural mechanisms supporting learning from feedback that is substantially delayed from the original response. Since the consequences of one’s actions often do not become known until after a delay, it is important to understand whether delayed feedback can produce neural responses similar to those elicited by immediate-feedback presentation. We investigated this issue by using functional magnetic resonance imaging (fMRI) as participants performed a paired-associate learning task with 180 distinct trials. Feedback indicating response accuracy was presented immediately, after a delay of 25 min, or not at all. Both immediate and delayed feedback led to significant gains in accuracy on a posttest, relative to no feedback. Replicating previous work, we found that the caudate nuclei showed greater activation for positive feedback than for negative feedback when the feedback was presented immediately. In addition, delayed feedback also led to differential caudate activity to positive versus negative feedback. Delayed negative feedback also produced significant activation of the putamen and globus pallidus (the lentiform nucleus), relative to no feedback and delayed positive feedback. This suggests that the caudate nucleus is sensitive to the affective nature of feedback, across different time scales, while the lentiform nucleus may be particularly involved in processing the information carried by negative feedback after a substantial delay.     

De-idealization by commentary: the case of financial valuation models

Is there a unique way to de-idealize models? If not, how might the possible ways of reducing the distortion between models and reality differ from each other? Based on an empirical case study conducted in financial markets, this paper discusses how a popular valuation model (the Discounted Cash Flow model) idealizes reality and how the market participants de-idealize it in concrete market situations. In contrast to Cartwright’s view that economic models are generally over-constrained, this paper suggests that valuation models are under-constrained. This serves as the reason why the relaxation of simplifying assumptions and concretization do not work as methods of de-idealization. The paper finds that financial market participants de-idealize models using commentary that takes the form of judgment. As a conclusion, a hypothesis is formulated that proposes that the more underdetermined the model is the bigger role narrative and other pragmatic elements play in the process of model application.     

Relationship of purported measures of pathological and nonpathological dissociation to self-reported psychological distress and fantasy immersion

In order to investigate both the psychometric structure of the Dissociative Experiences Survey (DES) and the discriminant validity of the DES-Taxon (Waller, Putnam, & Carlson, 1996) as a specific marker of pathological dissociation, 376 non-clinical community based respondents completed the DES and a battery of psychopathology and imaginative involvement self-report measures. The DES was scored for both the Taxon and the DES-Absorption subscale. A DES subscale purported to tap normative dissociative processes. The two DES subscales demonstrated substantial overlap, both with each other (r = .80) and with the self-report measures with both DES scales comparably associated with high levels of psychological distress. Both DES subscales were also associated with elevated levels of "normative" imaginative involvement (fantasy proneness, absorption, daydreaming immersion). We conclude that both DES scales are largely indistinguishable from each other in relation to other self-report measures of psychopathology and fantasy access.     

Latent memory for sensitization in Aplysia

In the analysis of memory it is commonly observed that, even after a memory is apparently forgotten, its latent presence can still be revealed in a subsequent learning task. Although well established on a behavioral level, the mechanisms underlying latent memory are not well understood. To begin to explore these mechanisms, we have used Aplysia, a model system that permits the simultaneous study of memory at the behavioral, cellular, and molecular levels. We first demonstrate that robust latent memory is induced by long-term sensitization training of the tail-elicited siphon withdrawal reflex. It is revealed by its ability to facilitate the subsequent induction of three mechanistically distinct temporal domains of sensitization memory: short-term, intermediate-term, and long-term memory. Under our training conditions, the latent memory persists for at least 2 d following the decay of original memory expression but appears to be gone by 4 d. Interestingly, we also find that latent memory is induced even in the absence of overt memory for the original training. These findings now permit the analysis of the cellular and molecular architecture of a common feature of learning and memory.     

Selection of gender‐incongruent applicants: No gender bias with structured interviews

Research suggests that the use of structured interviews can reduce gender bias in hiring. However, studies have been limited to gender‐neutral professions or laboratory simulations. The current study evaluated two components of the structured interview in a field sample of 691 applicants interviewing for a male‐dominated position of public transit operator. Multilevel modeling results show no significant differences in ratings across applicant gender with this highly structured interview. This relation was found in individual interviewer ratings and consensus panel ratings, as well as irrespective of interviewer gender and interviewer participation in comprehensive versus minimal training in structured interviewing. This study provided a conservative test in a male‐dominated profession to further validate the value of the structured interview for promoting equal hiring practices.     

Suppression mediates the effect of 5‐HTTLPR by stress interaction on depression

A number of studies have shown that the presence of short (S), as opposed to long (L), allele of the serotonin transporter‐linked polymorphic region (5‐HTTLPR) is associated with a higher risk for depression following exposure to stressful life events. However, many other studies failed to confirm this association. One reason for this inconsistency might be the fact that the interaction of the 5‐HTTLPR polymorphism with stress may relate not to depression per se, but rather to adaptive or maladaptive emotion regulation strategies. Here we show that individuals homozygous for the long allele respond to stressful events by reappraising their emotional meaning, which may hamper the harmful effect of stress on mental health. In S genotype carriers, on the other hand, stress triggers the appearance of intrusive thoughts and vain attempts to suppress them, which in this group acts as a mediator between stress and depressive symptoms. These findings are in line with neuroimaging studies showing that 5‐HTTLPR polymorphism has an effect on the connectivity among key areas involved in emotion regulation.     

Examination of a multi-factorial model of body-related experiences during pregnancy: the relationships among physical symptoms, sleep quality, depression, self-esteem, and negative body attitudes

The aim of this cross-sectional study was to investigate relationships among women's body attitudes, physical symptoms, self-esteem, depression, and sleep quality during pregnancy. Pregnant women (N = 215) at 15–25 weeks gestation completed a questionnaire including four body image subscales assessing self-reported feeling fat, attractiveness, strength/fitness, and salience of weight and shape. Women reported on 29 pregnancy-related physical complaints, and completed the Beck Depression Inventory, Rosenberg Self-esteem Scale, and Pittsburgh Sleep Quality Index. In regressions, controlling for retrospective reports of body image, more frequent and intense physical symptoms were related to viewing the self as less strong/fit, and to poorer sleep quality and more depressive symptoms. In a multi-factorial model extending previous research, paths were found from sleep quality to depressive symptoms to self-esteem; self-esteem was found to be a mediator associated with lower scores on feeling fat and salience of weight and shape, and on higher perceived attractiveness.
