Violence prevention programs with varying degrees of scientific support have proliferated in the United States and elsewhere. This paper previewed a broad range of programs involving youth, families, or systems that aimed to prevent or reduce violence-related behavior. The purpose of the review was to address critical issues concerning (1) target level of programming, (2) theory-driven versus problem-driven conceptualization, (3) cultural considerations, (4) developmental considerations, (5) intervention fidelity, and (6) outcome and impact assessment. Conclusions about these issues address tendencies and trends across programs. 相似文献

I contrast Bickle's new wave reductionismwith other relevant views about explanation across intertheoretic contexts. I then assess Bickle's empirical argument for
psychoneural reduction. Bickle shows that psychology is not autonomous from neuroscience, and concludes that at least some
versions of nonreductive physicalism are false. I argue this is not sufficient to establish his further claim that psychology
reduces to neuroscience. Examination of Bickle's explanations reveals that they do not meet his own reductive standard. Furthermore,
there are good empirical reasons to doubt that the cognitive approach to mind should be abandoned. I suggest that the near
future will not see a reduction of psychology to neuroscience, so much as a replacement of both sciences by an improved form
of neuropsychology. 相似文献

This study investigated the willingness of Israeli adolescents to seek help for emotional and health problems, and their preference for various helping agents. Nearly fifteen hundred students in grades 7-12 participated in a comprehensive survey of attitudes, health status, and concerns, and the data were analyzed. Gender and age were identified as factors associated with help-seeking attitudes. Females reported a higher level of distress and greater willingness to seek help than did males. Younger adolescents tended to state that they would turn to parents for help, whereas older adolescents increasingly preferred peers. In general, the adolescents preferred to seek help from family and peers for emotional and social problems, rather than turning to professionals. Adolescents in grades 9-10 reported the highest level of distress and were least willing to seek help for interpersonal problems and depressed mood. Overall, level of distress was not directly related to willingness to seek help. In subgroups of depressed and suicidal adolescents, an inverse relationship was found between willingness to seek help and levels of depression and suicidal ideation. Recommendations for health care services and counseling programs are discussed. 相似文献

Dissociating retention and access in working memory: an age-comparative study of mental arithmetic 总被引:4,自引:0,他引:4
In two experiments, young and older adults solved arithmetic chain tasks with single-digit operands, with or without a concurrent memory load of three or six digits. Variables in the arithmetic tasks had to be replaced by digits from the screen or from the memory set. A task-irrelevant concurrent load impaired neither speed nor accuracy of arithmetic in younger adults. In Experiment 2, this was also true for older adults. A large decrease in arithmetic performance was observed, however, when variables in the arithmetic task had to be substituted by digits from the memory list. Older adults had specific problems with this condition in Experiment 1, where the substitution involved two successive steps, but not in Experiment 2, where the substitution from memory could be done in a single step. The results are difficult to reconcile with models assuming a common resource for storage and processing. Rather, they are compatible with the hypothesis that a concurrent memory load interferes with a processing task only during the points of access to working memory. Further, even though access to working memory was found to be the critical source of concurrent-load interference, it was found to be insensitive to the effects of adult aging. 相似文献

The method of paired comparisons belongs to a small group of techniques that provide explicit information about the consistency of individual and aggregated choices. This article investigates the link between the individual- and group-level judgments by extending R. D. Luce's (1959) model, which was originally developed for individual choice behavior, to a mixed-effects paired comparison model. It is shown that standard multilevel software for binary data can be used to estimate the model. The interpretation of the paired comparison parameters and statistical model tests are discussed in detail. An extensive analysis of an experimental study illustrates the usefulness of a hierarchical approach in modeling multiple pairwise judgments. 相似文献

The present study examined adolescents' wisdom-related knowledge and judgment with a heterogeneous sample of 146 adolescents (ages 14-20 years) and a comparison sample of 58 young adults (ages 21-37 years). Participants responded to difficult and ill-defined life dilemmas; expert raters evaluated these responses along 5 wisdom criteria. Our findings confirmed that in contrast to adulthood, adolescence is a major period for normative age-graded development in knowledge about difficult life problems. Adolescents performed at lower levels than young adults but also demonstrated substantial age increments in performance. As expected, adolescents' performance varied as a function of criterion and gender. These results hold implications for research on adolescent development and for the development of wisdom-related knowledge and judgment. 相似文献

Risk as feelings 总被引:41,自引:0,他引:41
Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at a decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfields of psychology, they show that emotional reactions to risky situations often diverge from cognitive assessments of those risks. When such divergence occurs, emotional reactions often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms. 相似文献

Primary versus secondary insomnia in older adults: subjective sleep and daytime functioning 总被引:4,自引:0,他引:4
Most psychological research on insomnia has centered on primary insomnia (PI). Secondary insomnia (SI), though more common than PI, has received little attention because of its presumed unresponsiveness to treatment. The present study recruited older adults with PI, SI, and a comparison group of older adults with no insomnia (NI). Self-report assessments of sleep revealed no significant difference between the 2 insomnia groups. Daytime functioning measures found significant differences in impairment between the 3 groups with SI having the worst daytime functioning, followed by PI, which was worse than NI. Further analyses found substantial independence between sleep and daytime functioning. Implications of these findings for the clinical management of SI are discussed. 相似文献

意识和无意识知觉:注意和刺激特性间的相互补偿 总被引:11,自引:0,他引:11
该研究基于Exclusion任务,利用质的差异的研究范式,不仅确立了意识和无意识知觉在行为结果上的质的差异,而且发现刺激特性和注意在决定知觉意识时存在相互补偿的现象。在实验一中,当靶字短暂呈现时。被试用靶字补笔的比率高于基线水平;而当延长靶字呈现时间或提高对靶字的注意水平时,出现反转现象一用靶字补笔的比率低于基线水平。相对应地,在实验二中,分散注意条件下被试用靶字补笔的比率高于基线水平;而当注意集中或在分散注意条件下延长呈现时间时,出现了反转现象。 相似文献
