Studies of time estimation have provided evidence that human time perception is determined by an internal clock containing a temporal oscillator and have also provided estimates of the frequency of this oscillator (Treisman, Faulkner, Naish, & Brogan, 1992; Treisman & Brogan, 1992). These estimates were based on the observation that when the intervals to be estimated are accompanied by auditory clicks that recur at certain critical rates, perturbations in time estimation occur. To test the hypothesis that the mechanisms that underlie the perception of time and those that control the timing of motor performance are similar, analogous experiments were performed on motor timing, with the object of seeing whether evidence for a clock would be obtained and if so whether its properties resemble those of the time perception clock. The prediction was made that perturbations in motor timing would be seen at the same or similar critical auditory click rates. The experiments examined choice reaction time and typing. The results support the hypothesis that a temporal oscillator paces motor performance and that this oscillator is similar to the oscillator underlying time perception. They also provide an estimate of the characteristic frequency of the oscillator.  相似文献

This article describes a study conducted to identify the range of potential influences that a computer-assisted careers guidance system (PROSPECT (HE)) had on the functioning of organisations (careers services in higher education). Data from six institutions indicated that use of PROSPECT (HE) was associated with important and varied change within the organisations. It appears that when a careers service seeks opportunities for change, CACG systems can be an important catalyst for change in two respects: by providing a focal point for achieving previously established goals; or, as a consequence of system use, by making staff aware of the potential for new organisational goals.  相似文献

Gender differences in children's play activities, preferred school subjects, and occupational goals were examined in relation to such parental variables as toy-giving and chore assignment. Subjects were 245 children in grades K, 3, 6, and 8. Subjects completed questionnaires before and after Christmas asking what gifts they wanted, asked for, received, and liked best. They also were asked to name their friends and play activities, favorite and least-liked school subjects, occupational aspirations, and chores at home. Children generally wanted, asked for, received, and most-liked gender-typical toys. They were less likely to receive requested gender-atypical toys. Children's preferred activities, job aspirations and assigned chores were along gender-typical lines. Girls preferred masculine toys and jobs more than boys preferred feminine ones. With increasing age, both girls and boys increasingly preferred masculine toys and male friends. No gender differences in favorite or least-liked school subjects were found. School subject preference was related to gender-typing of occupational choice for girls but not boys.An earlier version of this paper was presented at the annual meeting of the American Psychological Association, Anaheim, California, 1983.  相似文献

A 3×2×2 incomplete factorial design was employed to test the effects of sex, dominance, and their interaction on leader emergence. The factors included dominance distribution (high/high, high/low, middle/middle), sex (male-female), and dyad composition (mixed sex-same sex). The subjects were all Caucasians and were pretested on the California Psychological Inventory Dominance Scale. The data revealed that dominance was a predictor of leader emergence in same-sex conditions where high-dominant individuals assumed the role of leader in much greater proportions than their low-dominant partners. In mixed-sex dyads, sex appeared to be a more potent predictor with males becoming leaders at levels greater than would be suspected given dominance levels.  相似文献

The act of rape violates two deeply held values of American culture: the right to justice and the right of physical integrity. Despite this fact, thousands of women are raped each year. The victim of rape often becomes the target of blame; in one aspect or another she is held accountable for her victimization. Through the use of rape myths, which are grounded in patriarchal expectations of gender role behavior, our culture unites the apparently dichotomous opposites of the rights to justice and physical integrity. While rape myths have received extensive attention from behaviorists, their communication through the mass media has been ignored. This study focuses on the use of, and opposition to, rape myths in prime-time television dramas, as well as discusses the implications of those depictions.This study was derived from my doctoral dissertation, which was directed by Dr. Pamela Benoit, University of Missouri — Columbia.  相似文献

CAUCASIAN LESBIANS' USE OF PSYCHOTHERAPY: A Matter of Attitude?   总被引:1,自引:0,他引:1  
Evidence suggests that a high proportion of lesbians seek psychological counseling. This study represents an empirical investigation of the disproportionate use of mental health services by lesbians, focusing on the hypothesis that lesbians place a greater value on psychotherapy than do nonlesbian women. Participants (100 lesbians and 309 nonlesbian women, 97% Caucasian) completed Surgenor's revision of the Attitudes Toward Seeking Professional Psychological Help Scale. Results indicate that the lesbian group had a significantly more positive attitude toward seeking psychological counseling than did the nonlesbian sample, regardless of whether or not they had experienced psychological counseling.  相似文献

TOWARD A FEMINIST UNDERSTANDING OF WOMEN AND POWER   总被引:1,自引:0,他引:1  
Both psychologists and feminists believe power is an important and ubiquitous concept, yet its definition and scope eludes both groups. In this introduction to a special issue on women and power, we suggest three points to help organize and interpret research in the area. First, definitions of power should center around the distinction between "power-over," the domination and control of one person or group over another, and "power-to" or personal empowerment. Second, power can be analyzed at different levels—societal, organizational, interpersonal, and individual—and, importantly, these levels interact. Third, power differences frequently underlie what appear to be gender differences in behavior; as society is currently configured, power and gender are never independent. Although the articles in this special issue often ask more questions than they answer, the present volume adds a feminist perspective to the psychological study of power.  相似文献

Group psychotherapy in a mixed gender group is seen as useful for treatment of the unique existential and emotional problems of the older woman. This article describes the first year of a psychotherapy group for older adults, four women and three men in their early fifties to late sixties. Some issues discussed unique to this age group were loss, isolation, changing body image, and changed political views. There were differences in reactions between the men and women. The major value of group psychotherapy for older women is seen as providing a safe arena for exploring current issues, integrating a sense of self, enhancing self-worth, and overcoming isolation and despair.  相似文献

The essential activity of group therapy consists of members taking an interest in each other by asking questions, showing concern, and conveying understanding. When members have not done this it has often been taken as a sign of resistance. A review of the research on helping suggests that there are four social factors that affect assistance giving in groups: 1) ambiguity-often people fail to give help because they are uncertain about who should give it, what should be done, and how it should be done; 2) often help is not given because of the way in which problems are presented; 3) the social comparisons that individuals make affect help-giving; and 4) there are costs associated with providing assistance. This discussion suggests that leaders can facilitate interaction among group members as teachers who clarify and as indirect helpers who redirect concerns back to group members.  相似文献

Summary The effects of noncontingency between subjects' responses and outcomes were examined with respect to treatment-and-posttest similarity and skill in the task. The experimental design consisted of three groups. The first group had to solve chess problems with objective solutions and received veridical feedback; each member of the second group faced problems with no objective solutions, and received the same feedback as the member of the first group he was yoked with, but without any control on it; the control group received a waiting task. It was found at the end of the experiment that the group with unsolvable problems was more depressed than the two other groups. The mid-strength players were the most sensitive to the manipulation, and the weakest players showed little effect of learned helplessness. It was also found that the effects were proportional to the degree of similarity between the treatment and the posttest. The results limit the domain of applicability of the learned-helplessness model.  相似文献
