Research suggests that gay men are at particular risk for body image dissatisfaction. This study seeks to extend research on gay men's body image concerns. A survey assessed the nature and correlates of body image dissatisfaction among 64 gay men. The survey included assessments related to involvement in and perceived acceptance within the gay community, social comparison tendencies, body image satisfaction, self-esteem, and depression. The results indicate that most participants were concerned with muscularity rather than weight. Greater social comparison tendencies and higher body mass index (BMI) were associated with greater body dissatisfaction. Although involvement and perceived acceptance in the gay community did not independently predict general body image dissatisfaction, there is evidence to suggest that the association between body image and self-esteem may be moderated by integration into the gay community, defined as involvement and perceived acceptance. Implications for the further study of gay men's body image are discussed.  相似文献

Children confront the formidable task of assimilating information in the environment and accommodating their cognitive structures to that information. Developmental science is concerned equally with two distinctive features of these processes: children's group mean level of performance through time and the standing of individual children through time. Prevailing opinion since the inception of the mental-measurement movement has been that individual development is unstable-that individual children change unpredictably in their abilities. We report results of a large-scale controlled, multivariate, prospective, microgenetic, 4-year longitudinal study that reveals a statistically significant cascade of species-typical cognitive abilities from infancy to childhood. Infancy is a recognizable starting point of life; we find that to a small but significant degree, infancy also represents a setting point in the life of the individual.  相似文献

In this study, changes in movement coordination caused by fatigue that developed during repetitive lifting were examined. Five men performed 6 times a 5-min bout of lifting an 8-kg barbell at 15 lifts/min, using two lifting techniques; one minimized trunk rotation (squat lift), and the other minimized rotation in the knee joint (stoop lift). Kinematics and dynamics were studied by means of movement analysis and inverse dynamics, using a two-dimensional linked segment model. Within-subject variation over repetitive lifts of the time course of joint angles was smaller than between-subjects variation on the first analyzed lift. Relative timing between joint rotations did not change significantly across repetitive lifts, except between knee and hip in the squat lift. No change of the lumbosacral torque over repetitive lifts was found. The adaptability of the neural control appeared to be sufficient to accommodate the strong changes of the input-output characteristics of the muscles caused by fatigue so that an essentially constant performance of the movement act was maintained.  相似文献

This study reports on a principal-components analysis of the Personality Adjective Check List (PACL) at the item level. Data came from a national sample of normal adults and included the responses-of 1,058 men and 1,194 women (N = 2,252). Analyses were conducted separately for men and women, and for the sexes combined. The scree test was applied to decide on the number of factors to extract. Retained factors were rotated by varimax and direct oblimin procedures. Results were very similar for each analysis, with coefficients of congruence for the five orthogonal factors obtained from men and women separately being .95, .92, .94, .94, and .92. The five unipolar personality dimensions isolated were interpreted as Aggressive/Dominant, Neurotic, Conscientious, Detached/Introverted, and Surgent/Extraverted. These were compared to item factors of the Millon Clinical Multiaxial Inventory (MCMI-I), MCMI-II, Adjective Check List (ACL), and to Norman's Big Five dimensions.  相似文献

This study examined the factor dimensions common to three different approaches to interpersonal behavior- the interpersonal circle, Millon's theory of personality, and a factor analytic (FA) approach. These were compared with the Norman (1963) "Big Five" factors. Measures employed were the revised Wiggins (1979) Interpersonal Adjective Scales, Strack's Personality Adjective Check List (1990), and the short form of the Lorr (1986) Interpersonal Style Inventory. Subjects were 146 college students (83 men and 63 women). A principal components analysis with varimax rotation revealed four distinct factors, based on a scree test, that accounted for 55.4% of the variance: Dominance-Submission, Extraversion-Introversion, Conscientiousness, and Agreeable-Disagreeable. Each of the models measured the circumplex axes of dominance and affiliation, but only the Millon (1969/1983) and FA approaches measured more than these elements, with the FA paradigm most sufficiently addressing all four. Dominance-Submission, the largest factor, was not explicit in the Big Five. Results suggest that earlier studies isolating five factors of personality may not have adequately represented this dimension.  相似文献

The stressing action of a medium-intensity, magnetostatic field was studied for several levels of intensity. Our purpose was (a) to verify a stressing action by display of the general adaptation syndrome Pattern on the growth rate of mice and (b) to establish the relation between effect and field intensity on the same variable. Eight groups of mice showed a linear relation. Moreover, stressing action was noticed at lower intensities than previously suggested.  相似文献

Abstract

Most personal, social and environmental stress results from our estrangement from nature's wise unconditional love within and about us. A new integrated ecology training program uniquely addresses this great challenge to the psychological community. Counseling students in natural areas over a thirty year period has produced ninety‐seven unique nature‐connecting activities that renew over forty‐nine inherent sensory fulfillments. These ecopsychology activities reduce our estrangement, its pain and adverse effects. Natural inborn feelings of love and understanding express themselves. They catalyze responsible relationships that fill the emotional voids which fuel our destructive habits, dependencies and abandonment feelings. They give natural areas added value as rejuvenators of our biological and spiritual integrity.  相似文献

Anger and aggression are common combat-related behavioral health problems. The impact of combat on anger and aggression appears to be largely attributable to symptoms of posttraumatic stress disorder (PTSD). Factors that moderate the purported pathway from combat to anger and aggression are poorly understood. We examined the conditional direct and indirect associations of combat exposure with self-reported anger and aggression using survey data collected from 592 U.S. Soldiers during a combat deployment in Afghanistan. Unit morale was examined as a moderator between combat exposure and PSTD symptoms, as well as the indirect association of combat exposure with anger and aggression via PTSD symptoms, controlling for depression symptoms. Results indicated that unit morale was negatively correlated with PTSD symptoms and self-reported anger and aggressive behaviors. Perceptions of unit morale moderated the direct association of combat exposure with PTSD symptoms. Unit morale also moderated the indirect association of combat exposure with anger and aggression through PTSD symptoms. Unit morale moderated the association of combat exposure with anger and aggression during combat operations by putatively mitigating the deleterious effect of combat on stress-related symptoms. The impact of policy and leadership on soldier and unit morale should be carefully considered given its protective role during combat operations.  相似文献

The first aim of the present study was to investigate whether differences in core deficits in ADHD subtypes lead to dissociable working memory profiles. The second aim was to compare the working memory profiles of inattentive students with those identified as having poor working memory, as they exhibit very similar behavioral profiles. Finally, the relationship between working memory and academic attainment in these groups were also of interest. Four groups of 9-year-olds were recruited: a community sample of children with inattentive symptoms, a clinically diagnosed group of children with ADHD-Combined, children with low working memory, and a healthy comparison group. They were assessed on measures of working memory, IQ, academic attainment, and sustained attention. The findings indicated that the combined and inattentive subtypes could not be distinguished on the basis of their working memory profile. In contrast, those with inattentive symptoms did better on the short-term memory tasks than the low working memory group. The majority of all three atypical groups performed very poorly in reading and math. This pattern can be interpreted as reflecting the link between working memory and academic attainment, even in those with attention problems.  相似文献
