Experimental effects of receiving negative weight-related feedback: a weight guessing study

The effects of receiving negative verbal weight-related feedback on the mood, self-esteem, and body image of restrained and unrestrained eaters were investigated. Female undergraduate students either reported their current weight (no feedback) or had their weight guessed as 15 lb higher than their actual weight (negative feedback) by an experimenter who presented herself as either an undergraduate (peer) or graduate student (non-peer). Participants overall had higher anxiety and felt “fatter” in the negative feedback condition. When this feedback came from a peer they felt fatter, more dissatisfied with their bodies, and, for restrained eaters, more depressed, as compared to when it came from a non-peer. These results provide empirical evidence that negative weight-related feedback produces adverse psychological consequences for young women, especially restrained eaters, and suggest the importance of peers’ perceptions of weight.     

Trajectories and predictors of indirect aggression: results from a nationally representative longitudinal study of Canadian children aged 2-10

The purposes of this study were to model the development of indirect aggression among a nationally representative sample of 1,401 Canadian children aged 4 at T2, 6 at T3, 8 at T4 and 10 at T5, and to examine predictors of trajectory group membership from T1 (age 2) child, familial, and parenting variables. Using a semi-parametric group-based modeling approach, two distinct trajectories were identified: "increasing users" comprising of 35% of the sample and "stable low users" comprising of 65% of the sample. Using logistic regression analyses to distinguish these two groups, we found that for girls, more frequent, increasing use of indirect aggression was associated with prior prosocial and physically aggressive behavior, low SES and low parental social support at age 2. For boys, increasing use of indirect aggression was associated with prior parenting issues at age 2-inconsistency and less positive parent-child interactions. Although this study provides unique information regarding the early development of indirect aggression and its predictors, more longitudinal research is needed to fully understand its development.     

A comparison of 13-year-old boys with attention deficit and/or reading disorder on neuropsychological measures

This study compared 13 year-old-boys with attention deficit disorder (ADD) and/or reading disability (RD), and controls with neither disorder on a battery of verbal and nonverbal neuropsychological measures. The aim was to examine whether ADD was associated with a qualitatively distinct pattern of deficits compared with RD. None of the measures differentiated the boys with ADD-only from the controls; the only deficit associated with ADD was slightly lower IQ. RD, on the other hand, was associated with deficits in memory and verbal skills.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and involves several Departments of the University of Otago.

The structure and correlates of self-reported symptoms in 11-year-old children

Self-reports of DSM-III symptomatology were obtained from 792 11-year-old children using the Diagnostic Interview Schedule for Children (DISC). We report results concerning 13 subscales derived from the DISC. Factor-analysis of the subscales suggested a broad distinction between externalizing and internalizing disorder for boys' self-report. For girls, two separate internalizing factors representing anxiety and depression emerged. We also found sex differences in correlates of self-reported disorder. Finally, we examined agreement between child and parent and teacher reports. Overall, agreement was relatively low, although somewhat higher for child-parent than for child-teacher.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and the Departments of Education and Health, and involves several departments of the University of Otago.

Sociotropy and perceptions of interpersonal relationships as predictors of eating disturbances among college women: two prospective studies

The authors examined the relationship between sociotropy and perceptions of interpersonal relationships and subsequent eating disorder symptoms among young women. In Study 1, 118 women from a liberal arts college in northern Wisconsin completed self-report measures of sociotropy, perceived close social support, and eating disorder symptoms. The women returned 6 weeks later to complete the same measures. After controlling for initial levels of reported eating disturbances, higher levels of Time 1 sociotropy and reductions in perceived social support at Times 1 and 2 made unique contributions to eating disturbances at Time 2, although the interaction of Time 1 sociotropy and Time 2 social support did not add to the model. In Study 2, 138 women completed measures of eating disturbances, sociotropy, and interpersonal hassles on two occasions, 10 weeks apart. Self-reported eating pathology at Time 1 accounted for most of the variance in Time 2 eating disorder symptoms, but increased eating disturbances also were predicted by measures of interpersonal hassles. A final regression analysis using combined samples indicated that both T1 and T2 measures of interpersonal functioning made unique contributions to changes in reported eating disturbances. In sum, the findings suggested that perceptions of reduced support in close relationships and increased interpersonal hassles contribute to increases in reported eating disturbances among college-aged women, independent of baseline levels of eating disturbances and a highly sociotropic personality style.     

Behavioral and Psychological Symptoms that Predict Cognitive Decline or Impairment in Cognitively Normal Middle-Aged or Older Adults: a Meta-Analysis

Neuropsychology Review - Epidemiological studies have revealed that behavioral and psychological (or non-cognitive) symptoms are risk factors for cognitive decline in older adults. This study aimed...     

Brief presentations are sufficient for pigeons to discriminate arrays of same and different stimuli

Four pigeons first learned to discriminate 16-item arrays of same from different pictorial stimuli. They were then tested with reduced exposure to the pictorial arrays, brought about by changes in the stimulus viewing requirement under fixed-ratio (FR) and fixed-interval (FI) schedules. Increasing the FR requirement enhanced discriminative performance up to 10 pecks; increasing the FI requirement enhanced discriminative performance up to 5 s. Exposures to the stimulus arrays averaging only 2 s supported reliable discrimination. Pigeons thus discriminate same from different stimuli with considerable speed, suggesting that same-different discrimination behavior is of substantial adaptive significance.     

The effect of experience on children's ability to show response and place learning

From a developmental perspective, it has been reasoned that over the course of development children make differential use of available landmarks in the surroundings to orient in space. The present study examined whether children can learn to apply different spatial strategies, focusing on different landmark cues. Children aged 7 and 10 years were tested on an object‐location memory task in which they learned a location relative to a direct cue or to indirect cues. Both age groups performed equally well on the direct test condition. However, children 7 years of age had difficulties with orienting relative to the indirect landmarks. Interestingly, their performance increased significantly with more relevant experience. Different explanations for these findings are discussed.     

Threats to communion and agency mediate associations between stressor type and daily coping

Background and Objectives: Basic human values have been categorized into two dimensions: those that are self or agentically focused, and those that are other or communally focused. We apply this model to cognitive appraisals of stress and argue that threat appraisals also fall into these two dimensions. The mediating roles of communal and agentic threats in linking stressors with coping responses were examined. Design: A daily process methodology was used. Methods: Three-hundred and fifty undergraduate students were followed midday and evening over one week, completing structured electronic diaries regarding their experiences of the past half-day. Participants described stressors in open-ended format, which were then coded into social stress, achievement stress, and other stress categories. They also completed scales measuring stress appraisals and coping. Results: Communal threat mediated links between social stressors and empathic responding, support seeking, and confrontation. Agentic threat mediated links between achievement stressors and empathic responding, support seeking, confrontation, and problem solving. Conclusions: Individuals tend to cope in ways that maintain communion when they perceive communion to be threatened; they tend to cope in ways that maintain agency when they perceive agency to be threatened.
