Distinctions Between Two Expectancies in the Prediction of Maladaptive Eating Behavior

In this longitudinal study, the authors provide support for the validity of the claim that differences in the nature of the reinforcement that adolescent girls expect from eating contribute to the development of different forms of maladaptive eating. The learned expectancy that eating is pleasurable and rewarding predicted higher levels of social/celebratory overeating across the first year of middle school but did not predict higher levels of clinical binge eating. In contrast, the expectancy that eating helps one manage negative affect predicted higher levels of binge eating but not of social/celebratory overeating across the same time period (n = 394). The results also supported a reciprocal model in which binge eating predicted higher levels of the expectancy that eating will manage negative affect but not that eating is pleasurable and rewarding; conversely, social/celebratory overeating predicted higher levels of the expectancy that eating is pleasurable and rewarding but not that eating will manage negative affect.     

The role of dialogic processes in designing career expectations

This article examines the role played by dialogic processes in the designing or redesigning of future expectations during a career guidance intervention. It discusses a specific method (“Giving instruction to a double”) developed and used during career counseling sessions with two recent doctoral graduates. It intends both to help them outline or specify a career expectation and to create a means to observe the involved dialogic processes. This method was designed within the framework of the “making oneself self” model (Guichard, 2004, 2005, 2009). Dialogic processes were analyzed by referring to (a) this model's conceptualization of individual reflexivity, (b) the Benveniste general linguistic theory, and (c) the concept of “acts of thought”, as recently developed from the Peirce semiotic theory. It appeared that each of these two graduates favored different dialogic processes and acts of thought and evolved accordingly. One of them re-read her whole life and created a new career expectation. The other worked on his previous one to move it from the past university laboratory where he wrote his thesis to a future expected job in a specific private company.     

Toward an exploration of feeling of strangeness in schizophrenia: perspectives on acousmatic and everyday listening

The aim of this study was to investigate abnormal perceptual experiences in schizophrenia, in particular the feeling of strangeness, which is commonly found in patients' self-reports. The experimental design included auditory complex stimuli within 2 theoretical frameworks based on "sensory gating deficit" and "aberrant salience," inspired from conventional perceptual scales. A specific sound corpus was designed with environmental (meaningful) and abstract (meaningless) sounds. The authors compared sound evaluations on 3 perceptual dimensions (bizarre, familiar, and invasive) and 2 emotional dimensions (frightening and reassuring) between 20 patients with schizophrenia (SCZ) and 20 control participants (CTL). The perceptual judgment was rated on independent linear scales for each sound. In addition, the conditioning-testing P50 paradigm was conducted on 10 SCZ and 10 CTL. Both behavioral and electrophysiological data confirmed the authors' expectations according to the 2 previous theoretical frameworks and showed that abnormal perceptual experiences in SCZ consisted of perceiving meaningful sounds in a distorted manner and as flooding/inundating but also in perceiving meaningless sounds as things that become meaningful by assigning them some significance. In addition, the use of independent scales to each perceptual dimension highlighted an unexpected ambivalence on familiarity and bizarreness in SCZ compatible with the explanation of semantic process impairment. The authors further suggested that this ambivalence might be due to a conflicting coactivation of 2 types of listening, that is, every day and musical (or acousmatic) listening.     

Colic: What's maternal mental health got to do with it?

Families can benefit when pediatric and mental health professionals have a greater appreciation of psychological and relational issues that arise in the course of caring for an infant with colic. The Infant Behavior, Cry, and Sleep Clinic is a multidisciplinary, clinical intervention for parents who identify infant crying as adversely affecting infant, parental, and/or family functioning. Pairing pediatric and mental health expertise provides parents with strategies to manage infant colic within a context that recognizes parental mental health needs. Clinical case material illustrates varying responses and degrees of psychological distress in mothers whose infants have colic. Treatment approaches to colic that take into account maternal mental health needs may contribute to more optimal infant, maternal, and family outcomes.     

Attenuated response to methamphetamine sensitization and deficits in motor learning and memory after selective deletion of β-catenin in dopamine neurons

In the present study, we analyzed mice with a targeted deletion of β-catenin in DA neurons (DA-βcat KO mice) to address the functional significance of this molecule in the shaping of synaptic responses associated with motor learning and following exposure to drugs of abuse. Relative to controls, DA-βcat KO mice showed significant deficits in their ability to form long-term memories and displayed reduced expression of methamphetamine-induced behavioral sensitization after subsequent challenge doses with this drug, suggesting that motor learning and drug-induced learning plasticity are altered in these mice. Morphological analyses showed no changes in the number or distribution of tyrosine hydroxylase-labeled neurons in the ventral midbrain. While electrochemical measurements in the striatum determined no changes in acute DA release and uptake, a small but significant decrease in DA release was detected in mutant animals after prolonged repetitive stimulation, suggesting a possible deficit in the DA neurotransmitter vesicle reserve pool. However, electron microscopy analyses did not reveal significant differences in the content of synaptic vesicles per terminal, and striatal DA levels were unchanged in DA-βcat KO animals. In contrast, striatal mRNA levels for several markers known to regulate synaptic plasticity and DA neurotransmission were altered in DA-βcat KO mice. This study demonstrates that ablation of β-catenin in DA neurons leads to alterations of motor and reward-associated memories and to adaptations of the DA neurotransmitter system and suggests that β-catenin signaling in DA neurons is required to facilitate the synaptic remodeling underlying the consolidation of long-term memories.     

A Dual Route in Explaining Health Outcomes in Natural Disaster1

Human beings seem to be resilient and have a great capacity to overcome adverse circumstances. One apparent variable that may predict people's emotional and physical health after a trauma is their general level of psychological well‐being ( McMillen, Smith, & Fisher, 1997 ). The current study explores the role of subjective vitality and the perception of stress as mediators between general life satisfaction and post‐trauma physiological and psychological health related to the Canadian 1998 Ice Storm. Results of this dual route indicate that satisfaction with life positively predicted subjective vitality and negatively predicted perceived stress. In turn, subjective vitality lead to lower levels of ill‐health, whereas perception of stress lead to higher levels of physical symptoms and depression.     

THE DISRUPTIVE EFFECT OF SELF-OBJECTIFICATION ON PERFORMANCE

Self-objectification is the act of viewing the self, particularly the body, from a third-person perspective. Objectification theory proposes numerous negative consequences for those who self-objectify, including decreased performance through the disruption of focused attention. In the current study, we examined whether women in a state of self-objectification were slower to respond to a basic Stroop color-naming task. Results showed that regardless of the type of word (color words, body words, or neutral words), participants in a state of self-objectification exhibited decreased performance. This study lends further evidence to objectification theory and highlights the negative performance ramifications of state self-objectification.     

Indirect influence of maternal social contacts on mother-child interactions: A setting event analysis

Fourteen mother-child dyads who had sought psychological help for severe interaction problems took part in a study that investigated the relationship between maternal social interactions with adults outside the family and mother-child interactions in the home. Social interactions outside the family were based on maternal self-reports; mother-child interactions in the home were based on direct observations and included both base-rate and sequential measures. Results indicated that mothers were significantly more aversive toward their children on days in which they had themselves experienced a high proportion of aversive interactions with adults than on days in which they had not. This higher level of aversiveness was evident in their responses to both aversive and nonaversive child behavior and could not be attributed to any corresponding change in child behavior. Implications for research and clinical practice are discussed.This work appeared first as a paper presented at the 92nd Annual Convention of the American Psychological Association, Toronto, August 1984.

ACTIVITÉ MÉTACOGNITIVE DE L'ENFANT ET DIFFICULTÉ DE LA TÂCHE COGNITIVE

The influence of the type of difficulty of a cognitive task on metacognitive activity (metacognitive experiences and metacognitive strategies) was studied in six- and eight-year-old children. Children had to make decisions about the correspondence of statements and drawings presented in pairs one after the other, starting either with a statement, or with a picture. They encounter two kinds of difficulties: (1) one due to the information conveyed by drawing (non-correspondence with the statement); (2) another due to the order in which the statements and drawings are presented: when the drawing comes first the child must retain it in his memory until a statement can guide him in his decoding of it; this difficulty is unexpected given the expectations the child has due to the cognitive task proposed. The principal findings were as follows: (1) Compared to the six-year-olds, the eight-year-olds demonstrated three times more metacognitive control strategies for expressing information, more cognitive skills (reasoning), and a higher level of performance (understanding and recall). (2) The two types of difficulties do not have the same effects: (a) the difficulty due to the information conveyed by the drawing leads to an increase in the latency time; the performance (understanding) is not as good; (b) in the case of difficulty due to the statement-drawing order, twice as many verbalizations expressing metacognitive experiences and a decrease in the latency time were observed. The interpretation of the findings underscores the importance for the child of the indicators he has to orient him in mobilizing metacognitive and cognitive activities.
