Infant temperament and maternal parenting self-efficacy predict child weight outcomes

Relationships between infant negative reactivity and self-regulation, parenting self-efficacy, and child weight outcomes were examined. Greater observed negative reactivity predicted more child weight gain when mothers had lower parenting self-efficacy. Lower mother-reported self-regulation predicted a greater child weight status. Results highlight potential early risk/protective factors.     

Perceptions of Vulnerability: A Target Characteristics Approach to Disability,Gender, and Victimization

This article takes an intersectional approach to how gender and disability affect the likelihood of experiencing violent or sexual victimization in a young adult cohort. Using data from the National Longitudinal Study of Adolescent Health (Add Health) Wave 4, I adopt a target characteristics approach to victimization. A visible signifier of disability increases the risk of violent and sexual victimization. Disability status itself increases the risk of sexual victimization. Gender interacts with disability, as visible signifiers of impairment affect only women while the effect of disability on sexual victimization is stronger for men.     

Neural correlates of stimulus response and stimulus outcome shifting in healthy participants and MS patients

Introduction

Adaptation to changing situations can be mediated by two strategies: (1) Evaluation of a response and (2) Evaluation of outcome values in relation to objects. Previous studies indicate that response shifting is associated with a network comprising the left frontal cortex and parietal cortex connected by the superior longitudinal fascicle, whereas outcome evaluation is associated with a network consisting of the orbitofrontal cortex, amygdala and uncinate fascicle. However, these studies rarely compared both kinds of adaptation directly and existing fMRI studies with healthy subjects are not informative about the role of the two fiber systems.

Methods

We analyzed stimulus response shifting and stimulus outcome shifting in two studies, one fMRI-study on healthy participants and one study on patients with MS involving structural MRI (Diffusion Tensor Imaging, Voxel Based Morphometry, Ventricular volumetry). Two tasks were used, identical in presentation but different in instruction, controlling for effects of lower level processing. In the SRS task, participants had to perform a “Go” or “NoGo” response depending on a stimulus change: if the stimulus remained the same, they had to continue with the former type of response, if it changed they had to adapt their response pattern. In the SOS task they had to perform a “Go” response only if the presented stimulus corresponded to that of an internal alternating series.

Results

fMRI findings showed that SRS is related to a bilateral parietal-premotor network. In the left hemisphere the prefrontal cortex was also involved. SOS was lateralized to the right hemisphere, particularly to the anterior temporal pole and amygdala, and the inferior parietal cortex. MS patients impaired on this task suffered from lesions in the right uncinate fascicle and showed an enlarged right frontal lateral ventricle.

Conclusion

With physically identical tasks, a functional neuronal segregation can be demonstrated for stimulus response shifting (bilateral activations with a focus in the left prefrontal cortex) and stimulus outcome shifting (right anterior temporal lobe and right supramarginal gyrus).     

Enhanced Cardiac Perception Is Associated With Increased Susceptibility to Framing Effects

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task‐irrelevant emotional stimuli on decision‐making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky‐choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results show a positive association between cardiac awareness and the framing effect, accounting for 24% of the variance in the framing effect. These findings demonstrate that good interoceptive skills are linked to poorer performance in risky choices based on ambivalent information when implicit bias is induced by task‐irrelevant emotional information. These findings support a dual process perspective on decision‐making and suggest that interoceptive skills mediate effects of implicit bias on decisions.     

Women Inmate Substance Abusers’ Reactivity to Visual Alcohol, Cigarette, Marijuana, and Crack-Cocaine Cues: Approach and Avoidance as Separate Dimensions of Reactivity

Despite the growing recognition for multidimensional assessments of cue-elicited craving, few studies have attempted to measure multiple response domains associated with craving. The present study evaluated the Ambivalence Model of Craving (Breiner et al. Alcohol Research and Health 23:197–206, 1999; Stritzke et al. 2007) using a unique cue reactivity methodology designed to capture both the desire to use (approach inclination) and desire to not consume (avoidance inclination) in a clinical sample of incarcerated female substance abusers. Participants were 155 incarcerated women who were participating in or waiting to begin participation in a nine-month drug treatment program. Results indicated that all four substance cue-types (alcohol, cigarette, marijuana, and crack cocaine) had good reliability and showed high specificity. Also, the validity of measuring approach and avoidance as separate dimensions was supported, as demonstrated by meaningful clinical distinctions between groups evincing different reactivity patterns and incremental prediction of avoidance inclinations on measures of stages of change readiness. Taken together, results continue to highlight the importance of measuring both approach and avoidance inclinations in the study of cue-elicited craving.     

The freud-jones letters

Abstract

Despite over a hundred years of writings about the history of psychoanalysis, from the point of view of professional intellectual historians this field remains amateurish in terms of solid scholarship. This edition of the Freud-Jones letters illustrates many of the long-standing problems. Although Jones was never one of Freud's personal favorites, it takes a subtle reading of the evidence to see the full nature of the tensions between the two. It is surprising, given the length of this text, how much additional surviving material might profitably been added.

Aside from serious shortcomings to this edition of Freud's correspondence, for example the longstanding orthodox tilt against Sandor Ferenczi, nothing like the tendentiousness associated with other editions of Freud's letters has taken place here. Future generations who get to see the full volumes of Freud's letters are going to have trouble recreating the human circumstances under which he was working. The Freud-Jones letters will remain of key interest to specialists. By now most know certain key historiographical failings on Jones's part, and it may be time now to underline how much he succeeded in accomplishing.     

A Contingency Approach to Specializing an Industrial Sales Force

Abstract

Psychographic, sociocultural and functional specialization are three alternative forms of deploying sales forces currently used by firms in combination with the traditional bases of specialization. Despite their usage, these forms have received little recognition and acceptance in the marketing literature. Because there is no single best form of specialization for all firms, this article proffers a contingency model of specialization whereby the optimal form(s) of specialization is dependent on the accurate analysis of twelve situational variables.     

Psychological and behavioural effects of bone density screening for osteoporosis

Abstract

To examine the psychological effects of bone density measurement, 298 women were assessed two weeks before the bone density scan, immediately before the scan, after the results, a week later and three months later. For the group as a whole, ratings of anxiety and perceived vulnerability were lower at the three month follow-up than at the initial assessment. Women who received a low bone mineral density (BMD) result were more anxious and reported more osteoporosis-preventive behaviours at the three month follow-up than women who received a high BMD result; these differences had not been apparent at the initial assessment Women with low BMD results had higher ratings of perceived vulnerability after the scan, although for some of these ratings there were group differences before the scan. Women with a low BMD result showed a decrease in ratings of the seriousness of a below-average result, which may reflect minimization of the health threat
