The primary aim of the study was to examine the relationship between media exposure and body image in adolescent girls, with a particular focus on the ‘new’ and as yet unstudied medium of the Internet. A sample of 156 Australian female high school students (mean age?=?14.9 years) completed questionnaire measures of media consumption and body image. Internet appearance exposure and magazine reading, but not television exposure, were found to be correlated with greater internalization of thin ideals, appearance comparison, weight dissatisfaction, and drive for thinness. Regression analyses indicated that the effects of magazines and Internet exposure were mediated by internalization and appearance comparison. It was concluded that the Internet represents a powerful sociocultural influence on young women’s lives. 相似文献

We modelled the associations between the HEXACO dimensions of personality, Social Dominance Orientation (SDO), Right‐Wing Authoritarianism (RWA) and prejudice towards dangerous, derogated and dissident groups (N = 454 undergraduates). Consistent with a Big‐Five model, low Openness to Experience predicted RWA and therefore dangerous and dissident group prejudice. As predicted, low Emotionality (and Openness) rather than Agreeableness predicted SDO and therefore derogated and dissident group prejudice. Comparison with meta‐analytic averages of Big‐Five data supported expected similarities and differences in the association of Big‐Five and HEXACO models of personality with ideology. Finally, Honesty‐Humility simultaneously predicted increases in RWA but decreases in SDO, and thus opposing effects on prejudice. These opposing effects have gone unidentified in research employing Big‐Five models of personality structure. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

The purpose of this study is to examine the association between parental socio-economic status (SES) and childhood neurocognition
and behavior in children with chromosome 22q11.2 deletion syndrome (22q11DS). Although undoubtedly, the deletion of genes
in the 22q11.2 interval is primarily responsible for the psychological manifestations, little is known about the role of the
environment in either mitigating or contributing to these problems. We examined the association of parental socio-economic
status (SES) with cognition and behavior in children with 22q11DS (n = 65) and matched healthy control subjects (n = 52), since SES is a component of family resources. We found that in children with 22q11DS, higher SES correlated with better
overall functioning (p < .01) and social skills (p < .01), and less frequent oppositional defiant behavior (p < .001). These findings were in contrast to the control subjects in whom SES correlated with cognition and achievement, but
not behavior. Our results indicate that environmental factors influence the behavioral phenotype in children with 22q11DS,
providing a framework for developing appropriate interventions. As such, genetic counseling for families with 22q11DS may
include consideration of family resources and inclusion of other health professionals, such as social workers, to explore
with the family available social supports and resources. 相似文献

Previous research findings have linked caregiver deprivation and emotional neglect with sensitivity to threatening cues. The present preliminary study investigated whether dysfunctions of the medial temporal lobe could underlie these associations. Using fMRI, we measured medial temporal lobe responses to emotional faces (angry, fearful, happy, neutral) among 30 youths. Eleven of the youths had a history of caregiver deprivation and emotional neglect. Attention states (i.e., attention to anger, fear, or physical attributes, or passive viewing) were systematically manipulated. Relative to comparison youths, youths with a history of caregiver deprivation and emotional neglect showed significantly greater left amygdala and left anterior hippocampus activation during the processing of threatening information. To our knowledge, these findings are the first to demonstrate altered medial temporal lobe function during the processing of threat cues in youths with a history of caregiver deprivation and emotional neglect. 相似文献

Evidence about a suspect's behavioural similarity across a series of crimes has been presented in legal proceedings in at least three different countries. Its admission as expert evidence, whilst still rare, is becoming more common thus it is important for us to understand how such evidence is received by jurors and legal professionals. This article reports on a qualitative analysis of mock jurors' deliberations about expert linkage analysis evidence. Three groups of mock jurors (N = 20) were presented with the prosecution's linkage analysis evidence from the USA State v. Fortin I murder trial and expert evidence for the defence constructed for the purposes of the study. Each group was asked to deliberate and reach a verdict. Deliberations were video‐recorded and subject to thematic content analysis. The themes that emerged were varied. Analysis suggested that the mock jurors were cautious of the expert evidence of behavioural similarity. In some cases they were sceptical of the expert. They articulated a preference that expert opinion be supported using statistics. Additional themes included jurors having misconceptions concerning what is typical offender behaviour during rape which suggests there is a need for expert linkage analysis evidence regarding behavioural similarities and the relative frequencies of crime scene behaviours.

This study examined effectiveness of Home‐Start, a program designed to support parents with young children. The aims were (a) to examine whether Home‐Start improved maternal well‐being and (b) to examine whether Home‐Start led to changes in the behavior of mothers or children. Self‐reported and observational data were collected in two waves, using data from 54 mothers and their children between 1.5 and 3.5 years of age who participated in this intervention program for 6 months. These data were compared to 51 comparison families who reported need for parenting support. The results showed a significant improvement in perceived parenting competence, but no effects on maternal depressive moods. Mixed results were found for parenting behavior: Parental consistency and observed sensitivity improved significantly in the Home‐Start group whereas no effects were found on the other parenting variables. Child behavioral problems seemed to diminish at the second measurement in both groups, and therefore these changes cannot be attributed to Home‐Start. 相似文献

Phantom contours are a visual illusion that can define regions with distinctive boundaries when no real surrounding edges exist. Spatial-frequency sensitivity is known to vary reliably across the visual-processing pathways, as does temporal-frequency sensitivity. Given that the effect of temporal frequency on phantom-contour detection has been previously established, and that the relationship between spatial frequency and temporal frequency is known, two experiments were designed to measure the highest level of spatial frequency that would still allow reliable pattern detection at different temporal frequencies by using the phantom-contour paradigm. The results revealed that phantom-contour detection is impaired when the stimulus has a high spatial-frequency content and that phantom-contour perception is supported by low spatial frequencies. 相似文献

This paper compares the statement ‘Mathematics is the study of structure’ with the actual practice of mathematics. We present
two examples from contemporary mathematical practice where the notion of structure plays different roles. In the first case
a structure is defined over a certain set. It is argued firstly that this set may not be regarded as a structure and secondly that what is important
to mathematical practice is the relation that exists between the structure and the set. In the second case, from algebraic
topology, one point is that an object can be a place in different structures. Which structure one chooses to place the object
in depends on what one wishes to do with it. Overall the paper argues that mathematics certainly deals with structures, but
that structures may not be all there is to mathematics.

Mothers of children with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for an ADHD diagnosis themselves,
which is likely associated with impairments in parenting. The present study utilized a multi-method assessment of maternal
ADHD and parenting to examine the extent to which maternal ADHD symptoms are associated with maladaptive parenting. Participants
included 70 6–10 year old children with DSM-IV ADHD and their biological mothers. Results suggested that mothers with higher
levels of ADHD symptoms reported lower levels of involvement and positive parenting and higher levels of inconsistent discipline.
During observed parent–child interactions, maternal ADHD symptoms were negatively associated with positive parenting, and
positively associated with negative parenting and repeated commands before giving the child an opportunity to comply. Given
prior research suggesting that maladaptive parenting behaviors are risk factors for the later development of conduct problems
among children with ADHD, these findings have important clinical implications for family-based assessment and treatment of
ADHD. 相似文献
