Jamie M. Yockey 《Sex roles》1978,4(6):917-927
Women's sex-role perceptions and behavior were studied from the perspective of role theory, with an emphasis on examining the situational nature of female sex roles and the degree of consensus among women concerning female sex roles. The perceived appropriateness and expected outcome for sex-role characteristics and the actual enactment of masculine and feminine behaviors were examined for women in social and work situations. It was hypothesized that feminine behaviors prevail in social situations and masculine behaviors in work situations. This hypothesis was clearly supported for perceived appropriateness and actual behavior, but not for expected outcome. For this variable, the predicted pattern was found only in the social situation. It was also hypothesized that the degree of consensus across women is higher for feminine than for masculine characteristics, but this pattern was found only for perceived appropriateness and actual behavior in the social situation.This article is based on a dissertation submitted to the University of Florida in partial fulfillment of the requirements for a doctoral degree. Portions of this work were presented at the annual meeting of the American Psychological Association in September 1976. The author would like to express her appreciation to Lawrence J. Severy and Marvin E. Shaw for their advice throughout this study.  相似文献

This study examined perceived social support among children of parents diagnosed with cancer. Twenty-nine participants, ages 18–38, who had been children when one of their parents was diagnosed with cancer provided demographic information and participated in an interview about the impact of their parent’s illness on their lives. Five common themes characterized participants’ perceived social support received during their parent’s illness: (a) listening and understanding; (b) encouragement and reassurance; (c) tangible assistance; (d) communication about cancer and treatment; and (e) engaging in normal life experiences. Depending on the circumstances, however, a given type of social support was perceived to be helpful to some, while perceived by others as ineffective or detrimental. Differences in respondents’ perceptions of the effects of specific forms of received social support speak to the need for individualized support for children of cancer patients based upon each child’s specific needs and circumstances.  相似文献

Raven’s Progressive Matrices is a widely used test for assessing intelligence and reasoning ability (Raven, Court, & Raven, 1998). Since the test is nonverbal, it can be applied to many different populations and has been used all over the world (Court & Raven, 1995). However, relatively few matrices are in the sets developed by Raven, which limits their use in experiments requiring large numbers of stimuli. For the present study, we analyzed the types of relations that appear in Raven’s original Standard Progressive Matrices (SPMs) and created a software tool that can combine the same types of relations according to parameters chosen by the experimenter, to produce very large numbers of matrix problems with specific properties. We then conducted a norming study in which the matrices we generated were compared with the actual SPMs. This study showed that the generated matrices both covered and expanded on the range of problem difficulties provided by the SPMs.  相似文献

Under fixed‐ratio schedules, transitions from more to less favorable conditions of reinforcement (rich‐to‐lean transitions) usually generate extended pausing. One possible explanation for this effect is that stimuli associated with rich‐to‐lean transitions are aversive and, thus, extended pausing functions as escape. The purpose of this study was to characterize further the aversive function of different transitions, and the stimuli associated with them, by allowing pigeons to choose to complete select ratios in the presence of either a mixed‐schedule stimulus or a transition‐specific multiple‐schedule stimulus. The mixed schedule was preferred during transitions that signaled an upcoming lean reinforcer (rich‐to‐lean and lean‐to‐lean), whereas the multiple schedule was preferred during transitions that signaled an upcoming rich reinforcer (lean‐to‐rich and rich‐to‐rich). These findings support the notion that stimuli associated with rich‐to‐lean (and to some extent lean‐to‐lean) transitions can function aversively; whereas stimuli associated with other transitions (e.g., lean‐to‐rich and rich‐to‐rich) can function as conditioned reinforcers. When the opportunity to choose between schedule‐correlated stimuli was available, however, choice latency was controlled exclusively by the multiple‐schedule stimulus. That is, the opportunity to select the mixed schedule did not attenuate rich‐to‐lean pauses, suggesting that extended pausing may be more than simply escape.  相似文献

This study examined the effectiveness of a stress management intervention for sheltered homeless adults with mental illness. Twelve intervention participants received a 6-week, 1-hour psychoeducation group combined with a 20-minute meditation. Eleven matched pairs did not receive intervention and served as controls. At 1 week post study, intervention participants reported a statistically significant reduction in perceived stress (Z=??2.285, p < .02, d=??1.176) compared to controls. No differences were found at 1 week post study between intervention and control participants on reported quality of life. This study provides pilot data on the effectiveness of an occupation-based stress management program for sheltered homeless adults and warrants further study.  相似文献

Working memory deficits are present in a substantial proportion of children with ADHD, and converging evidence links these deficits with ADHD-related behavioral and functional impairments. At the same time, working memory is not a unitary construct, and evidence is lacking regarding the role of several components of this system in ADHD. Preclinical behavioral studies are needed to fractionate the multicomponent working memory system, determine which specific subcomponent(s) are impaired in ADHD, and more importantly link these subcomponent(s) with specific ADHD-related behavioral symptoms/functional impairments. The current study reflects one piece of that puzzle, and focuses on the episodic buffer component of working memory. Across multiple testing days, a well-characterized sample of 86 children ages 8–13 (M=10.52, SD=1.54; 34 girls; 64% Caucasian/Non-Hispanic) with ADHD (n=49) and without ADHD (n=37) completed three counterbalanced working memory tests that were identical in all aspects except the key subcomponent process (phonological, visuospatial, episodic buffer). Gross motor movement during these and control tasks were measured using 4 high-precision actigraphs. There was no evidence of group differences in gender, age, SES, or IQ. Bayesian mixed-model ANOVAs indicated that the ADHD group performed significantly worse on all three working memory tests (d=1.17–1.44) and was significantly more hyperactive than controls (d=0.66–1.05) during the visuospatial and episodic buffer tests. In contrast, the ADHD and Non-ADHD groups were equivalent with regard to effects of episodic buffer demands on performance and hyperactive behavior. The most parsimonious conclusion is that the episodic buffer is likely intact in ADHD, and unrelated to ADHD hyperactivity symptoms.  相似文献
