In visual search tasks, attention can be guided to a target item--appearing amidst distractors--on the basis of simple features (e.g., finding the red letter among green). Chun and Jiang's (1998) contextual cuing effect shows that reaction times (RTs) are also speeded if the spatial configuration of items in a scene is repeated over time. In the present studies, we ask whether global properties of the scene can speed search (e.g., if the display is mostly red, then the target is at location X). In Experiment 1A, the overall background color of the display predicted the target location, and the predictive color could appear 0, 400, or 800 msec in advance of the search array. Mean RTs were faster in predictive than in nonpredictive conditions. However, there was little improvement in search slopes. The global color cue did not improve search efficiency. Experiments 1B-1F replicated this effect using different predictive properties (e.g., background orientation-texture and stimulus color). The results showed a strong RT effect of predictive background, but (at best) only a weak improvement in search efficiency. A strong improvement in efficiency was found, however, when the informative background was presented 1,500 msec prior to the onset of the search stimuli and when observers were given explicit instructions to use the cue (Experiment 2).  相似文献

The purpose of this study was to determine the percentage of borderline patients who first engaged in self-mutilation as children and to compare the parameters of their self-harm to those of borderline patients who first harmed themselves at an older age. Two hundred and ninety inpatients meeting both Revised Diagnostic Interview for Borderlines (DIB-R; Zanarini, Gunderson, Frankenburg, & Chauncey, 1989) and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. ref.) (DSM-III-R; APA, 1987) criteria for borderline personality disorder were interviewed about their history of self-mutilation. Of the 91% with a history of self mutilation, 32.8% reported first harming themselves as children (12 years of age or younger), 30.2% as adolescents (13-17 years of age), and 37% as adults (18 or older). Using logistic regression analyses and controlling for baseline age, it was found that those with a childhood onset reported more episodes of self-harm, a longer duration of self-harm, and a greater number of methods of self-harm than either those with an adolescent or adult onset to their self-mutilation. The results of this study suggest that a sizable minority of borderline patients first engage in self-harm as children and that the course of their self-mutilation may be particularly malignant.  相似文献

This study examined the relative importance of four major BPD features, that is, affective instability, disturbed interpersonal relationship, unstable sense of self, and behavioral impulsivity, in explaining the presence, initiation, repetition, and discontinuation of non-suicidal self-injury (NSSI) among a 2-year follow-up sample of 4,782 (68.5% girls) Hong Kong Chinese secondary school students. Affective instability, disturbed interpersonal relationship and behavioral impulsivity were significantly associated with the presence of NSSI both concurrently and longitudinally. These three BPD features were also related to the future initiation of NSSI. On the other hand, only behavioral impulsivity made a significant contribution to the repetition of NSSI. Additionally, a lower level of affective instability was also associated with quitting NSSI. We discussed some possible mechanisms underlying the effects of different BPD features on different developmental stages of NSSI.  相似文献

Interpersonal loss and self-mutilation   总被引:1,自引:0,他引:1  
Self-mutilation was hypothesized to increase in frequency during periods of interpersonal loss in a treatment program for seriously disturbed adolescents. The study examined changes in the frequency of acts of self-mutilation, aggression, and running away for 32 teenagers who experienced interpersonal loss when staff members left employment. Data were collected for a 4-year period. Statistical findings indicated that the frequency of self-mutilation increased significantly during the time period of anticipated loss, 2 weeks prior to staff terminations. There was no significant increase in the frequency of self-mutilation immediately following the staff terminations. Also, there was no significant change in the rates of aggression or running away either before or after the loss events. It was concluded that the time of anticipated loss was the period of highest risk for these adolescents in terms of self-mutilative behavior.  相似文献

This study investigates the role of familism values in fostering socialization experiences that promote prosocial behavioral tendencies among Mexican American adolescents. Two hundred and four Mexican American mothers and their adolescent children (104 girls, age M = 10.91 years) completed measures of familism values, prosocial parenting practices, and prosocial behavioral tendencies. Structural equation modeling tests indicated that mothers' familism values are related to parenting behaviors that promote prosocial behavioral tendencies, which in turn are related to adolescents' perception of prosocial parenting practices. Furthermore, adolescents' perception of prosocial parenting practices is related to familism values and prosocial behavior tendencies. Last, the relation between adolescents' perception of prosocial parenting practices and prosocial behavioral tendencies is partially mediated by familism values. These findings are consistent with the theoretical suggestion that the transmission of traditional familism values may serve as a social medium through which prosocial behavioral tendencies are fostered among Mexican American adolescents.  相似文献

In most countries, adolescents' access to abortion is limited by restrictions on legal abortion. Abortion is legal in the United States, but many states require parental consent or notification. Legislation mandating parental consent has been justified by several assumptions, including high risk of psychological harm from abortion, adolescents' inability to make an adequately informed decision, and benefits of parental involvement. Empirical data raise questions about the first 2 assumptions: Studies suggest a relatively low risk associated with abortion, and adolescents seeking abortion appear to make an informed choice. Less is known about effects of parental involvement. The authors review available research and discuss policy debates over parental consent in the United States and the international context.  相似文献

Friendship and adjustment among adolescents   总被引:2,自引:0,他引:2  
This study investigated the relation of friendship and emotional adjustment in adolescents. Both quantitative (popularity, mutual friendships, and number of friends) and qualitative dimensions (perceived positive friendship quality and conflict) of friendship were used. Participants were 618, mostly European American, 8th-, 10th-, and 12th-graders. Structural equation modeling showed that positive friendship quality was the only friendship variable that predicted adjustment. An examination of gender effects indicated that this relation held only for boys. The quantitative aspects of friendship had a small, indirect effect on adjustment through their effects on positive quality. Conflict had a negative effect on positive quality and this effect was stronger for girls than for boys. The role of adolescents' perception in adjustment was highlighted and suggestions for future research were made.  相似文献

The study examined consistencies and differences between 60 parents and their adolescent children with behavioral problems when rating the adolescents' strengths. The parents and teenagers agreed on most of the strength categories of the Behavior and Emotional Rating Scale. However, caretakers rated the adolescents as more involved in family life, while the adolescents rated themselves as more involved in school activities.  相似文献

The study examined whether the four constructs of forgivingness found in adults—propensity to lasting resentment, sensitivity to circumstances, willingness to forgive, and willingness to avenge—were already in place among adolescents. It also examined the differences in propensity to forgive and related constructs between young adolescents and older adolescents. More than 500 adolescents (124 sixth graders, 170 seventh graders, 135 eighth graders, and 78 ninth graders) were presented with a slightly modified version of the Forgivingness Scale (Mullet, Barros, Frongia, Usai, Neto, & Rivière-Shafighi, 2003 Mullet, E., Barros, J., Frongia, L., Usai, V., Neto, F. and Rivière-Shafighi, S. 2003. Religious involvement and the forgiving personality. Journal of Personality, 71: 119. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). The same four-factor structure that was found among adults was also found among adolescents. Scores regarding sensitivity to circumstances and willingness to forgive were lower among older adolescents than among younger adolescents. Scores regarding lasting resentment and willingness to avenge were higher among older adolescents than among younger adolescents.  相似文献

This study was directed toward the identification of components of wellness in adolescents ages 12-17. Content for wellness-learning games aimed at youth was derived from the professional judgment of an advisory panel composed of experts in preventive medicine, health education, and adolescent development. The panel was polled by mail in a Delphi-like series of structured inquiries to gather information about the physical, social, and emotional characteristics of healthy adolescents and to identify the knowledge, attitudes, and behaviors appropriate to the promotion or support of those characteristics. The study resulted in a consensus of 39 attributes considered important in the development of healthy adolescents.  相似文献

The extent of loneliness among late adolescents was assessed by means of the Revised UCLA Loneliness Scale. Findings suggest that although moderate loneliness was reported by most participants, a number of young people evidenced a high degree of loneliness. A comparison of lonely and nonlonely adolescents yielded relatively few significant differences. Of particular interest, however, was the finding that lonely and nonlonely adolescents use different strategies to deal with feelings of loneliness. Implications for working with lonely adolescents are offered.  相似文献

Heroes and heroines among American adolescents   总被引:1,自引:0,他引:1  
Based upon the analysis of questionnaire responses of 1092 high school students, an attempt was made to assess the type of heroes and heroines most often chosen. The major findings are that high school students have more heroes than heroines, that they have an approximately equal number of personal heroes and heroines, and that the preference for heroes is not altered when the sex or race of the respondents is considered. The findings are explained both by the greater numbers of males than females in public professional roles and by the greater salience of male than female professional role models. Implications of the possible effects of hero and heroine choices for sex-role identification are discussed.  相似文献

Schizotypal experiences and depressive symptoms are quite common among adolescents, and have been considered as risk markers for schizophrenia-spectrum and mood disorders. The main goal of the present study was to analyze the relationship between schizotypal experiences and depressive symptoms in a community sample of non-clinical adolescents. The sample comprised a total of 1653 participants, 794 male (48%), with an average age of 15.94 years (SD = 1.23). Results showed that schizotypal traits and depressive symptoms were closely related at a subclinical level. Canonical correlation analysis indicated that the two sets of variables shared approximately 48% of the variance. The study of the dimensionality underlying the subscales of the self-reports revealed the presence of three components, namely: Depressive, Anhedonia and Reality Distortion. These results are convergent with previous studies conducted in both clinical and non-clinical samples, indicating overlap between schizotypal experiences and depressive symptoms.  相似文献

The present study tested the model minority and inferior minority assumptions by examining the relationship between academic performance and measures of behavioral health in a subsample of 3,008 (22 %) participants in a nationally representative, multicultural sample of 13,601 students in the 2001 Youth Risk Behavioral Survey, comparing Asian Americans (N = 408) and African Americans (N = 2,600). Specifically, the study examined associations of students’ self-reported grades with suicide risk, substance abuse, and violent behaviors. The findings revealed that high academic performance is a protective factor against behavioral health problems for both ethnic groups. The results raise questions about the focus on high achievement among Asian Americans versus academic underachievement among African Americans. Implications for theory, research, training and practice in addressing the mental health implications of achievement behavior in Asian American and African American youth are discussed.  相似文献
