Although researchers have long hypothesized a relation between gender role orientation (i.e., masculinity and femininity) and body dissatisfaction, findings have been inconsistent. The current study employed a measure of recalled childhood gender nonconformity to examine gender role behaviors in association with body dissatisfaction among an ethnically diverse (76% Caucasian, 2% African American, 8% Asian, and 16.4% Hispanic American) group of predominantly college-aged males of both homosexual (n = 129) and heterosexual (n = 52) orientation. Consistent with past research, gay males reported more body dissatisfaction and recalled more childhood gender atypical behaviors (e.g., disliking athletics, playing with dolls). Group differences in body dissatisfaction, however, disappeared when childhood gender nonconformity was statistically controlled, suggesting childhood atypical gender role behavior may place males at greater risk for adult body dissatisfaction. A within-group analysis also found that a high feminine subtype of gay males had greater body dissatisfaction than less feminine subtypes had. Results support the assertion that gender role behaviors may contribute to body dissatisfaction among gay males.  相似文献

The authors investigated the effects of gender on the social dynamics and outcomes of conversations involving 120 children (mean age = 8 years 7 months). Children were taught particular values for different shaped counters and placed in same-gender or mixed-gender pairs with children who were taught different values. Pairs were asked to add the counters together to make a total of 100. Conversations were coded in terms of communication acts and simultaneous speech acts. Boys used more controlling acts overall and more negative interruptions in mixed-gender pairs. Girls used more affiliating acts. All children used more collaborative communication in same-gender pairings. Children whose perspective dominated used more controlling and comparatively fewer affiliating acts. When children reached a compromise, conversations were more collaborative.  相似文献

This study examined the effect of school-based kindergarten transition policies and practices on child outcomes. The authors followed 17,212 children from 992 schools in the Early Childhood Longitudinal Study-Kindergarten sample (ECLS-K) across the kindergarten school year. Hierarchical linear modeling revealed that the number of school-based transition practices in the fall of kindergarten was associated with more positive academic achievement scores at the end of kindergarten, even controlling for family socioeconomic status (SES) and other demographic factors. This effect was stronger for low- and middle-SES children than high-SES children. For low-SES children, 7 transition practices were associated with a .21 standard deviation increase in predicted achievement scores beyond 0 practices. The effect of transition practices was partially mediated by an intervening effect on parent-initiated involvement in school during the kindergarten year. The findings support education policies to target kindergarten transition efforts to increase parent involvement in low-SES families.  相似文献

The authors modeled sources of error variance in job specification ratings collected from 3 levels of raters across 5 organizations (N=381). Variance components models were used to estimate the variance in ratings attributable to true score (variance between knowledge, skills, abilities, and other characteristics [KSAOs]) and error (KSAO-by-rater and residual variance). Subsequent models partitioned error variance into components related to the organization, position level, and demographic characteristics of the raters. Analyses revealed that the differential ordering of KSAOs by raters was not a function of these characteristics but rather was due to unexplained rating differences among the raters. The implications of these results for job specification and validity transportability are discussed.  相似文献

Researchers have found that stimulation of the medial nucleus of the amygdala (MeA) in male rats increases appetitive copulatory behavior directed toward an anestrous female but suppresses copulation with an estrous female (C. P. Stark et al., 1998). The objective in the present study was to determine if the behavioral change produced by stimulation of the MeA was dependent on chemical and/or visual cues from the conspecific. The author reports that electrical stimulation of the MeA in male rats increased the frequency of mounting and investigative behavior directed toward a male conspecific. However, these effects were limited to those subjects that had no prior sexual experience. Results are discussed in terms of possible experience-dependent alterations in neural response patterns within the MeA and related areas.  相似文献

Watching a rubber hand being stroked, while one's own unseen hand is synchronously stroked, may cause the rubber hand to be attributed to one's own body, to "feel like it's my hand." A behavioral measure of the rubber hand illusion (RHI) is a drift of the perceived position of one's own hand toward the rubber hand. The authors investigated (a) the influence of general body scheme representations on the RHI in Experiments 1 and 2 and (b) the necessary conditions of visuotactile stimulation underlying the RHI in Experiments 3 and 4. Overall, the results suggest that at the level of the process underlying the build up of the RHI, bottom-up processes of visuotactile correlation drive the illusion as a necessary, but not sufficient, condition. Conversely, at the level of the phenomenological content, the illusion is modulated by top-down influences originating from the representation of one's own body.  相似文献

The ability to divide attention enables people to keep track of up to four independently moving objects. We now show that this tracking capacity is independently constrained in the left and right visual fields as if separate tracking systems were engaged, one in each field. Specifically, twice as many targets can be successfully tracked when they are divided between the left and right hemifields as when they are all presented within the same hemifield. This finding places broad constraints on the anatomy and mechanisms of attentive tracking, ruling out a single attentional focus, even one that moves quickly from target to target.  相似文献

We conducted four experiments to investigate whether adults can exert attentional strategic control over nonlexical and lexical processing in written spelling to dictation. In Experiment 1, regular and irregular words were produced either in a nonword context (regular and irregular nonwords) or in a word context (high-frequency regular and irregular words), whereas in Experiment 2, the same set of words was produced either in a regular nonword or in an irregular low-frequency word context. Experiment 3 was a replication of Experiment 2 but with increased manipulation of the context. In Experiment 4, participants had to produce either under time pressure or in response to standard written spelling instructions. Regularity effects were found in all the experiments, but their size was not reliably affected by manipulations intended to increase or decrease reliance on nonlexical processing. More particularly, the results from Experiment 4 show that adults can speed up the initialization of their writing responses to a substantial degree without altering regularity effects on either latencies or spelling errors. Our findings suggest that, although adults are able to generate an internal deadline criterion of when to initialize the writing responses, nonlexical processing is a mandatory process that is not subject to attentional strategic control in written spelling to dictation.  相似文献

This article examined the applicability of the interpersonal circumplex (IC) to the observable social behaviors of children during parent-child interactions. In Study 1, the observational ratings of behaviors of 117 children (mean age = 9.88 years) were examined. Randomization tests of hypothesized order relations found that these behaviors tended to occur in the circular pattern predicted by the IC. To illustrate the applicability of the IC to children's behavior, Study 2 (n = 94) used the circular structure of children's behavior to longitudinally examine children's participation in two risk behaviors, smoking cigarettes and consuming alcohol. Results indicated that children who behaved in an arrogant-calculating manner were at risk for smoking cigarettes and children who behaved in an assured-dominate manner were at risk for drinking alcohol 1 year later. Implications of these results are discussed in terms of their relevance for helping researchers better understand and categorize children's interpersonal behaviors.  相似文献
