Based on experimental research on helping and survey findings on drunk driving intervention, we selected 28 variables for study that might relate to informal intervention in a drunk driving situation. We tested six hypotheses by categorizing the 28 variables into personal (12), relationship (4), situational (5), and individual response (7) aspects. Bivariate correlations and multivariate logistic regression analyses were performed between these 28 predictor variables and intervention for 303 college students (192 females and 111 males). Three personal, one relationship, three situational, and four individual responses in situation variables were correlated significantly with intervention. Four significant predictors emerged in the stepwise logistic regression equation: knowing the driver well; having a conversation that encouraged the respondent to intervene; perceiving the driver as needing help; and the respondent's feeling able to intervene. All hypotheses received at least some confirmation in these results, but noteworthy discrepancies from expectations emphasize the need to appreciate differences between studies of helping behavior in the laboratory and this natural form of helping behavior.  相似文献

Two studies examined the novel proposal that implicit theories of intelligence (C. S. Dweck & E. L. Leggett, 1988) moderate both the effects of performance trends on ability inferences and the perceived diagnosticity of temporal versus normative feedback. Results from 613 adolescents and 42 teachers confirmed that entity theorists perceived initial outcome as more diagnostic and inferred higher ability in another (Study 1) and in the self (Study 2) in a declining outcome condition; incremental theorists perceived last outcome as more diagnostic and inferred higher ability in an ascending condition. Experimental induction of beliefs about ability had similar effects. As predicted, self-appraisal was affected more by temporal feedback among incremental theorists and by normative feedback among entity theorists. Results help resolve prior mixed findings regarding order effects and responses to temporal and normative evaluation.  相似文献

This article proposes and tests a formal cognitive model for the go/no-go discrimination task. In this task, the performer chooses whether to respond to stimuli and receives rewards for responding to certain stimuli and punishments for responding to others. Three cognitive models were evaluated on the basis of data from a longitudinal study involving 400 adolescents. The results show that a cue-dependent model presupposing that participants can differentiate between cues was the most accurate and parsimonious. This model has 3 parameters denoting the relative impact of rewards and punishments on evaluations, the rate that contingent payoffs are learned, and the consistency between learning and responding. Commission errors were associated with increased attention to rewards; omission errors were associated with increased attention to punishments. Both error types were associated with low choice consistency. The parameters were also shown to have external validity: Attention to rewards was associated with externalizing behavior problems on the Achenbach scale, and choice consistency was associated with low Welsh anxiety. The present model can thus potentially improve the sensitivity of the task to differences between clinical populations.  相似文献

This research examined the association of having a tattoo and engaging in premarital sexual intercourse. Data gathered from a convenience sample of 450 college students indicated that tattooed respondents were substantively and significantly more likely to be sexually active than nontattooed college students. Tattooed men became sexually active at a significantly earlier age than nontattooed men but no such difference was found between tattooed and nontattooed college women.  相似文献

Research in the burgeoning field of threat assessment has illuminated the importance of mental illness factors when considering risk of targeted violence-particularly related to government agencies and officials. The authors analyzed 127 cases investigated by a state law enforcement agency regarding threatening or other contacts toward public officials or state agency employees prompting security intervention. Univariate and discriminant analysis indicated that mentally ill subjects were significantly more likely to engage in more contacts as well as to make specific demands during such contacts. Mentally ill subjects were also more likely to articulate help-seeking concerns and employ religious themes, as opposed to using insulting, degrading, or ominous language toward the target or issuing complaints regarding policy issues. Contrary to other research, the mentally ill subjects within this sample were not significantly more likely to engage in approach behavior, a threshold for higher risk of violence. Implications for threat assessment activity are discussed.  相似文献

Research on psychological factors in helping behavior has been undertaken primarily in laboratory settings. Although this work has been instrumental in identifying psychological factors that influence helping, their role in naturally occurring helping behavior, such as informal drunk-driving intervention, is largely unknown. College students (N= 192) completed a questionnaire that assessed 11 possible reactions to the drunk driving situation, types of interventions, and their success. Over half of the students (55%, N= 10) reported having intervened to prevent someone from driving drunk. Using structural modeling, we examined the effect of various emotions and affective and cognitive reactions on the frequency and success of different types of informal drunk-driving intervention. Different reactions to the drunk driving situation influenced the number, type, and success of interventions used.  相似文献

Abstract— In probabilistic categorization tasks, the correct category is determined only probabilistically by the stimulus pattern Data from such experiments have been successfully accounted for by a simple network model, but have posed difficulties for exemplar models In the present article, we consider an exemplar model, CLEM (concept learning by exemplar memorization), which differs from previously tested exemplar models in that exemplar traces are assumed to be stored only when the subject has guessed or made a classification error Fits of CLEM to both learning and test data were comparable to those of the network model, and better than those obtained for a version of CLEM in which encoding was independent of the subject's response The implications of these results for the processes underlying classification decisions are discussed.  相似文献

The biomotometer, an electronic device that simultaneously measures activity and provides auditory feedback to the subject, was used in combination with material reinforcers in two experiments attempting to modify activity level in children. In the first study the activity level of an 11-year-old highly active boy was decreased below mean baseline during conditioning in a classroom setting. His level of activity returned to baseline when feedback was withdrawn. In the second study, activity level of a 10-year-old hypoactive boy was increased over mean baseline level during conditioning in a free-play setting, and returned to slightly below baseline during five extinction trials. Results of these studies indicate that the biomotometer is a useful instrument for modification of activity level.  相似文献

Activity level of 13 boys (aged 9–13) from a day hospital program was measured using actometers in classroom, gym, woodshop, and group therapy settings. Ratings of Ss' activity were obtained from mothers using the Werry scale, and from six clinical staff familiar with the Ss using the Davids scale. It was predicted that activity ratings would have situationally specific relationships with actometermeasured activity level according to the rater's opportunities for observation. Comparisons between measures indicated that all clinical staff ratings correlated significantly with actometer activity in the classroom (r=.49 to r=.73), while mothers' ratings correlated significantly with actometer activity in gym (r=.67), and woodshop (r=.77), and with overall activity (r=.65), a combined measure derived from actometer scores in the four conditions tested. Five of six clinical staff raters showed significant interrater reliability (r=.58 to r=.83). Results are discussed in terms of their implications for solution of current problems in assessment of activity level and hyperactivity.  相似文献

It is crucial that counselors recognize that the problem-solving process that occurs in a counseling situation is synonymous with classroom learning. It is imperative that counselors understand the nature of the problem-solving process and how to guide and nurture this process, to increase their own effectiveness and their counselees' growth. Understanding the concepts of risk taking and intrinsic and extrinsic reinforcement and their relationships to the counselees' problem-solving processes will allow counselors to establish their own counseling approaches and respond to the counselees' learning needs.
