The future career autobiography (FCA) is a narrative, discovery-based career intervention designed to assess individuals’ career hopes and dreams. In total, 134 low-income, ethnically and racially diverse middle school students participated in an FCA intervention through a yearlong grant-funded career development initiative. Using content analysis, we analyzed participants’ FCAs for socioeconomic status factors and lifestyle indicators. We found that participants articulated occupational and lifestyle factors more than education and income, and that there were differences based on biological sex, race, and ethnicity. We present pertinent results and discuss implications for counseling practice and future research.  相似文献

Persistent behavior maintained by unavoidable shocks   总被引:1,自引:1,他引:0       下载免费PDF全文
Squirrel monkeys were trained on a multiple schedule in which 10-min periods on a continuous shock avoidance schedule, indicated by a yellow light, alternated with 10-min periods on a 1.5-min variable interval schedule of food reinforcement (VI 1.5). A white light indicated that VI 1.5 was in effect, except for the middle 2 min of the period on VI 1.5, in which a blue light appeared and terminated with the delivery of a 0.5-sec unavoidable shock. Stable response rates developed in the avoidance and VI 1.5 components. However, the highest response rates occurred in the blue, preshock stimulus. A series of experiments showed that responding in the blue stimulus persisted even when responding had been extinguished on both the VI schedule of food reinforcement and the shock avoidance schedule. Responding in the blue stimulus ceased when the blue stimulus terminated without shock or when it terminated with a response-contingent shock. Each time responding ceased, it was restored by terminating the blue stimulus with an unavoidable shock. When the blue stimulus was on throughout each session and unavoidable shocks were delivered at regular 10-min intervals, responding was well maintained. These results show that in monkeys that have been trained on a continuous avoidance schedule, unavoidable shocks can maintain responding even under conditions where responses have no programmed consequences.  相似文献

In this study the authors investigated the relationship between the Male Role Norm Scales (MRNS; Thompson & Pleck, 1987) and gender-related attitudes and behaviors in a sample of 367 male counselors drawn from American Counseling Association (ACA), formerly the American Association for Counseling and Development (AACD), members. Results indicated that this group of men did not, in general, endorse traditional male roles as measured by the MRNS. When a degree of affiliation with these roles was found, however, it was predictive of violence proneness, intimacy style, and degree of perceived similarity to father. Implications for training and counseling are discussed.  相似文献

Summary A comparison was made between trajectories of reaches to visual targets by 6-months-old infants, with and without lateral prismatic displacement. In the No Prism condition, the major element of the movement veered towards the target, confirming the results of Mathew and Cook (1990). In the Prism condition, the prism did not affect hand position or movement direction at the beginning of the major element, but a lateral displacement was evident by the end of the element. This is taken as evidence that shifts in trajectory during the element were not due to visual guidance. It is suggested instead that these shifts may reflect correction based upon somatic feedback about position in relation to the visually specified goal of the movement. Evidence that the hand approached the virtual target supports the suggestion that any visual guidance was confined to the approach phase of the reach. Nevertheless, it appears that visual guidance was operating at this stage, since movement direction was displaced away from the virtual target and towards the real target.  相似文献

Research based mainly on non-national samples reports a greater affinity for animal rights among women than men, and proposes a greater relational role orientation among women that emphasizes caring for others to explain this difference. Using a recent national sample comprised of 11% African American and 89% white American respondents, we find that a relational role orientation fails to account for women’s greater support of animal rights. It does provide minor help in distinguishing animal rights advocates from nonadvocates, but only among women and only on one of two measures of animal rights support. We conclude by proposing women’s structural locations as well as the interplay between these locations and women’s role socialization as alternate explanations for gender differences in affinity for animal rights.  相似文献

Stimulus-independent thoughts (SITs) are streams of thoughts and images unrelated to immediate sensory input. Four experiments examined the contribution of aspects of working memory to production of SITs. In Experiments 1 and 2, interventions that were targeted on, respectively, phonological and visuospatial components of working memory both interfered with production of SITs, but there was evidence that these tasks also made demands on central executive resources. Experiments 3 and 4 specifically examined the hypothesis that production of SITs and control of nonproceduralized tasks both depend on central executive resources, and so should show mutual interference. In Experiment 3, prior practice on pursuit rotor and memory tasks reduced the interference with SITs from concurrent task performance. In Experiment 4, randomness within a task involving random-number generation was less when SITs were being produced concurrently than it was when they were not. The results suggest that production of SITs depends on central executive resources.  相似文献
