Studies investigating body image satisfaction among groups of different sexual orientations (i.e., gay men, lesbian women, and heterosexual men and women) have produced equivocal findings. To synthesise the available research, 27 studies (20 published and 7 unpublished) were meta-analysed (N=5220). Comparisons between heterosexual (n=1397) and gay men (n=984) produced a small effect size, with the former being slightly more satisfied with their bodies. An even smaller difference was observed for studies comparing heterosexual (n=1391) and lesbian women (n=1448), with greater levels of body satisfaction being evidenced by the latter group. Tests of homogeneity for each effect size were found to be highly significant. In an attempt to identify variables that may be responsible for the observed heterogeneity, the following categorical factors were assessed: the measures used to evaluate body satisfaction, date of study (1980s versus 1990s+), publication status (published or unpublished), and body weight. The results of this exploratory search for potential moderator variables as well as limitations of the current meta-analysis are discussed.  相似文献

Although children born preterm are at risk for neuropsychological impairments at school age and adolescence, including difficulties with visual motor integration, spatial/constructional skills, attention, arithmetic, and nonverbal executive functions, specific neuropsychological outcome has not been investigated adequately in preschoolers. Application of cognitive neuroscience tasks offers the opportunity to characterize early executive functions in young children born preterm. In a preliminary sample of 29 preschool children born preterm (M birth gestational age = 32.4 weeks), executive function outcome was compared to that of fullterm controls by contrasting performance on two prototypic delayed-response-type paradigms, Delayed Alternation and Spatial Reversal. Preschoolers born preterm correctly retrieved the reward on fewer trials on Delayed Alternation than did matched controls. Furthermore, preschool children born preterm used problem-solving strategies that included more perseverative errors than controls. These preliminary findings highlight the utility of cognitive neuroscience paradigms to understand neuropsychological outcome in preschool children born preterm and suggest areas of developmental vulnerability that may include dorsolateral prefrontal circuits.  相似文献

This study is a laboratory analogue investigation of variables that impinge upon the recall of detail about a simulated act of armed robbery among “eyewitnesses.” Specifically, this study sought to determine (1) whether recall of detail by Ss who watch the videotape of a simulated “armed robbery” taken by surveillance camera in a “convenience” store varies according to (a) the dress and appearance of the presumed “robber,” (b) the gender of the victim of the “robbery,” and/or (c) the gender of the “eyewitness”; and (2) whether such recall varies according to S’s inventoried psychological “needs.” Ss viewed the videotape of the simulated robbery under one of four conditions representing variations in the dress and appearance (“status”) of the alleged offender and the gender of the alleged victim; completed the Personality Adjective Inventory; and responded to a questionnaire concerning details of the alleged offense. Results indicate that the single statistically significant source of variance in accuracy of recall of detail is the experimentally manipulated “status” of the perpetrator; gender of victim and of subject contribute significantly neither in isolation nor in interaction. Inventoried psychological needs for “autonomy” and “change” are significantly but negatively and weakly correlated with accuracy among women Ss, while “change” alone is so correlated among men Ss. Findings are interpreted in accordance with theory and research in experimental social psychology and psychological criminology bearing upon person perception and role expectancy in relation to behavioral stereotypes. This study was supported in part through the Henry Rutgers Scholars Program at Rutgers College of Rutgers-The State University of New Jersey.

This investigation explored the risks of affectionate expressions in romantic relationships by examining the physiological and emotional implications of recalled expressed deceptive affectionate messages to romantic partners. Ninety‐nine participants were assigned to one of three conditions: deceptive affection, honest affection, or plans with a friend (control). Results indicate that individuals' blood pressure and heart rates are not differentially influenced when recalling deceptive affection compared to honest affection or common communication. Similarly, there were no differences in feelings of guilt and shame based on the motive for the deceptive expression. Posthoc analyses compared affectionate conditions (deceptive and honest) to the control condition and revealed no significant physiological differences. Implications for theory, methodological comparisons, and future research are discussed.  相似文献

In the context of a pre‐existing resource inequality, the concerns for strict equality (allocating the same number of resources to all recipients) conflict with the concerns for equity (allocating resources to rectify the inequality). This study demonstrated age‐related changes in children's (3–8 years old, = 133) ability to simultaneously weigh the concerns for equality and equity through the analysis of children's judgements, allocations, and reasoning in the context of a pre‐existing inequality. Three‐ to 4‐year‐olds took equity into account in their judgements of allocations, but allocated resources equally in a behavioural task. In contrast, 5‐ to 6‐year‐olds rectified the inequality in their allocations, but judged both equitable and equal allocations to be fair. It was not until 7–8 years old that children focused on rectifying the inequality in their allocations and judgements, as well as judged equal allocations less positively than equitable allocations, thereby demonstrating a more complete understanding of the necessity of rectifying inequalities. The novel findings revealed age‐related changes from 3 to 8 years old regarding how the concerns for equity and equality develop, and how children's judgements, allocations, and reasoning are coordinated when making allocation decisions.  相似文献

The present study investigated children's and adolescents’ social reasoning about parenting roles in the home, specifically ‘second‐shift parenting’ by a mother or father. Surveys were administered to children (age 10) and adolescents (age 13), nearly evenly divided by gender (N= 200) in which two hypothetical scenarios were evaluated. Participants were asked to evaluate and justify second‐shift parenting arrangements for the family overall, for the parent in the role, and for the child in the family. Results showed that participants expected mothers rather than fathers to take on the second‐shift role, and second‐shift parenting was evaluated as more unfair for fathers than for mothers. Personal choice reasoning was used for justifying arrangements for the second‐shift parent and moral reasoning was used for justifying arrangements for the child. Social reasoning about the context of parental caretaking roles was multifaceted and varied by age and gender of participant more so than by self‐reported personal family arrangements.  相似文献

This paper presents a theoretical approach of how simple, episodic associations are transduced into semantic and grammatical categorical knowledge. The approach is implemented in the hyperspace analogue to language (HAL) model of memory, which uses a simple global co-occurrence learning algorithm to encode the context in which words occur. This encoding is the basis for the formation of meaning representations in a high-dimensional context space. Results are presented, and the argument is made that this simple process can ultimately provide the language-comprehension system with semantic and grammatical information required in the comprehension process.  相似文献

Word frequency is one of the strongest determiners of reaction time (RT) in word recognition tasks; it is an important theoretical and methodological variable. The Ku?era and Francis (1967) word frequency count (derived from the 1-million-word Brown corpus) is used by most investigators concerned with the issue of word frequency. Word frequency estimates from the Brown corpus were compared with those from a 131-million-word corpus (the HAL corpus; conversational text gathered from Usenet) in a standard word naming task with 32 subjects. RT was predicted equally well by both corpora for high-frequency words, but the larger corpus provided better predictors for low- and medium-frequency words. Furthermore, the larger corpus provides estimates for 97,261 lexical items; the smaller corpus, for 50,406 items.  相似文献
