Student perceptions of barriers, facilitating factors, and information needs related to the consideration of careers in science and technology were investigated with a nationwide sample of talented high school senior women (N = 1017). Data were collected through a mailed questionnaire as part of a broader National Science Foundation project. Results of the study suggest that relatively few girls choose careers in science and technology because: They have doubts about combining family life with a science career; they lack information about steps in preparing for a science career; they believe influential adults; and they see few examples of the important role women can play in science. The data describing the students' perceptions of facilitating factors and information needs suggest that encouragement from family, access to role models, extra help and encouragement from science teachers, and information about careers in science, including the steps involved in preparation, might be influential in helping change perceptions of barriers to careers in science and technology.  相似文献

Three experiments are reported which examine the effects of experience with escapable shock either subsequent to (Experiment 1) or prior to (Experiments 2 and 3) a session of inescapable shock on the subsequently produced long-term analgesic reaction in rats. Experment 1 demonstrated that experience with escapable shock 4 hr after a session of inescapable tail shock completely reverses the analgesic response that is normally observed 24 hr later upon reexposure to shock. The escapability of the shock was shown to be the important factor in reversing the analgesic reaction, since subjects given inescapable shock in amounts equivalent to escape subjects exhibited no reduction in analgesia. Experiment 2 showed that experience with escapable shock 4 hr prior to a session of inescapable tail shock could also completely eliminate the long-term analgesic reaction. Experiment 3 replicated the results of Experiment 2, but employed a different escape task and temporal parameters in order to extend the generality of the findings, and to more closely match the procedures employed in behavioral experiments reported by J. L. Williams and S. F. Maier (Journal of Experimental Psychology: Animal Behavior Processes, 1977, 3, 240–253). The implications of these results for the areas of pain control and learned helplessness were discussed.  相似文献

Rats 30, 60, 90, and 120 days of age were fed 105 45-mg food pellets on a noncontingent VT 70-sec schedule during 14 daily 2-hr sessions. Every animal became polydipsic on this schedule when compared with a schedule in which 105 pellets were presented at the beginning of the session. Mean polydipsic ratios (schedule intake/control intake) ranged from 2.9–5.4. Water intakes (milliliters per 100g body weight) did not differ during the last five sessions as a function of age. The results are discussed with respect to the generality of the class of adjunctive behaviors.  相似文献

Social skills training for juvenile delinquents   总被引:2,自引:0,他引:2  
Twenty-seven incarcerated juvenile delinquents matched on the number of previous offenses, age, WISC-R IQ, and locus of control were assigned to a Social Skills. Discussion or Control group. Social skills training consisted of instruction, feedback, modeling, behavior rehearsal, social reinforcement and graduated homework assignments. All subjects were assessed before and after treatment on a variety of self-report, role-play and behavioral measures. Analyses of variance for difference scores indicated that the Social Skills group improved significantly more than the Discussion and Control groups, which did not differ. Appropriate interpersonal skills were learned, state anxiety was reduced, internal locus of control was increased, and significant shifts in adjustment to the institutional program were evidenced for the Social Skills group.  相似文献

Abstract. John Caiazza presents the current technoculture as the latest development in the ongoing conflict of science and religion that began with Tertullian in the third century. I argue that his presentation is historically inaccurate, because for most of Western history science and religion interacted with and cross‐fertilized each other. Contrary to Caiazza's misleading presentation, Western thought did not follow the dichotomous model polemically posed by Tertullian. I take issue with Caiazza's portrayal of postmodernism and his claim that technology is the foundation of an inherently secularist culture. I conclude by highlighting certain ethical challenges engendered by the prevalence of new technologies and present the dialogue of science and religion as uniquely qualified to address these challenges.  相似文献

Drawing on Thomas Ogden's notion of ‘reverie’, the role of self‐reflection in research interviewing is explored. Ogden views reverie as a co‐created intersubjective phenomenon, a ‘third’, distinct from both analyst and patient. Two face‐to‐face research interviews with adolescent depression sufferers are described, showing how reverie can be used to help overcome impasse, and develop research hypotheses. Participant‐centred research interviews were thus shown to be enhanced by psychoanalytically informed self‐reflection as accessed through reverie. The role of reverie in research interviewing, in part spontaneous and ineffable, in part defined and systematic, is discussed.  相似文献

Prior to 1651, Hobbes was agnostic about the existence of God. Hobbes argued that God’s existence could neither be demonstrated nor proved, so that those who reason about God’s existence will systematically vacillate, sometimes thinking God exists, sometimes not, which for Hobbes is to say they will doubt God’s existence. Because this vacillation or doubt is inherent to the subject, reasoners like himself will judge that settling on one belief rather than another is epistemically unjustified. Hobbes’s agnosticism becomes apparent once we attend to his distinctions between the propositional attitudes one might adopt towards theological claims, including supposing, thinking, having faith and knowing.  相似文献

In this paper, I consider Isaac Newton’s fevered accusation that John Locke is a ‘Hobbist.’ I suggest a number of ways in which Locke’s account of the mind–body relation could plausibly be construed as Hobbesian. Whereas Newton conceives of the human mind as an immaterial substance and venerates it as a finite image of the Divine Mind, I argue that Locke utterly deflates the religious, ethical, and metaphysical significance of an immaterial soul. Even stronger, I contend that there is good reason to suspect that Locke is a crypto-materialist, at least with respect to human beings, and in this respect, could reasonably be labeled a ‘Hobbist.’  相似文献
