Previous research has linked higher levels of hopelessness about one's future to violent behavior during adolescence; however, little is known about this relationship over time for adolescents. Using growth curve modeling, we tested the association between future orientation and violent behavior across the high school years of adolescence in a sample of African American youth (n = 681). Variation based on demographic characteristics (i.e., sex, SES, previous violence) was explored. At baseline, differences in violent behavior varied by demographic characteristics. Overall, violent behavior decreased with age. Higher levels of future orientation were associated with greater decreases in violent behavior over time. Demographic characteristics were not associated with change in violent behavior overtime. Our findings suggest that future orientation can act as a promotive factor for at risk African American youth. Interventions that help support the development of future goals and aspirations could play a vital role in violence prevention efforts. 相似文献

This study informs community science, and seeks to narrow the research-to-practice gap, by examining how the interpersonal networks within a setting influence individuals' use of interventions. More specifically, it explores the role of two network mechanisms-cohesion and structural similarity-in urban elementary school teachers' use of interventions designed to improve academic and behavioral outcomes for students. Lagged regression models examine how position in advice giving networks influenced weekly use of the daily report card and peer assisted learning by kindergarten through fourth grade teachers in three schools. Results indicate that intervention use spreads among teachers with similar patterns of advice-giving relationships (i.e., via structural similarity), rather than from teachers who are sources of advice (i.e., via cohesion). These results are consistent with findings in other settings, and suggest that researchers wishing to increase the use of an intervention should select change agents based on their patterns of their relationships, rather than on their direct connections. 相似文献

At issue in the present series of experiments was the ability to prospectively perceive the action-relevant properties of hand-held tools by means of dynamic touch. In Experiment 1, participants judged object move-ability. In Experiment 2, participants judged how difficult an object would be to hold if held horizontally, and in Experiments 3 and 4, participants rated how fast objects could be rotated. In each experiment, the first and second moments of mass distribution of the objects were systematically varied. Manipulations of wielding speed and orientation during restricted exploration revealed perception to be constrained by (a) the moments of mass distribution of the hand-tool system, (b) the qualities of exploratory wielding movements, and (c) the intention to perceive each specific property. The results are considered in the context of the ecological theory of dynamic touch. Implications for accounts of the informational basis of dynamic touch and for the development of a theory of haptically perceiving the affordance properties of tools are discussed. 相似文献

Those charged with assessing and managing threatening communications must utilize risk factors that are behavioral, operational, and reasonably attainable during investigations. This project examined 326 written correspondence cases of an inappropriate, disruptive, or threatening nature that targeted political officials, with the specific goal of identifying written content indicators of problematic approach behavior. Results revealed that subjects who engaged in problematic approach activity toward their targets had more criminal history, past threat assessment activity, familiarity with firearms, past substance use, and indicators of serious mental illness. Approachers were more likely to engage in multiple contact methods, target dispersion, more overall contacts, and prior contact with their target. Numerous content themes were associated with future problematic approach, including longer handwritten correspondence, referencing specific events, making demands, mentioning stressors, focus on personal themes, feeling their rights were violated, and expressing an intention to approach. Harassing, insulting, and threatening language was not related to approach behavior. The implications of these findings are wide-ranging for the practice of threat assessment. 相似文献

The DSM-5 Personality and Personality Disorders (PDs) Work Group has recommended a reformulation of the PD section, one component of which is a replacement of specified operational criteria with a prototype matching dimensional rating system. The Work Group indicated that prototype ratings have been demonstrated to have good interrater reliability. No study was cited to support this statement, and a review of the reliability literature does not support this claim. The one study that directly compared the reliability of prototype and DSM-IV criteria counting approaches found the DSM-IV approach was much more reliably applied. The Work Group cited 2 studies supporting the validity of the prototype matching approach, one of which had significant methodological limitations and the other changed the a priori threshold on the PD prototype dimensional rating scale to categorize patients into PD positive and negative groups. The Work Group also cited 2 studies suggesting that prototype matching approaches are preferred by clinicians. Several studies have raised concerns about the adequacy of psychiatric diagnostic evaluations conducted in routine clinical practice thereby raising questions about the value of studies of clinicians' preferences in comparing different diagnostic practices. In conclusion, if the prototype matching dimensional approach described in the DSM-5 draft proposal is adopted, then it will have been adopted with essentially no empirical support demonstrating improved reliability or validity. In fact, there is evidence that reliability will be worse than the DSM-IV approach. 相似文献

Three experiments explored whether patterns of eye movements during reading might help explain syntactic prominence effects
that are typically observed using reaction time tasks. Participants read sentences in which target words were in syntactically
prominent or syntactically less prominent positions. Across all three experiments, using three types of syntactic prominence
manipulations, there were fewer fixations and shorter reading times for words in more prominent positions, indicating that
enhanced accessibility of syntactically prominent words is not caused by increased processing time. Rather, syntactic prominence
appears to facilitate early encoding/lexical access and sentence integration processes while also, as shown previously, increasing
activation of concepts in a comprehender’s sentence or discourse representation. We propose that enhanced encoding and sentence
integration processes can be attributed to an increase in attentional resources for more prominent concepts, and that this
increase derives from readers’ immediate sensitivity to informational prominence contours that are signaled by syntax. 相似文献

Jordi Fernández has recently responded to my objection that his 'extrospectionist' account of self knowledge posits necessary and sufficient conditions for introspective justification which are neither necessary nor sufficient. I show that my criticisms survive his response unscathed. 相似文献

This study was designed to revisit the response bias hypothesis, which posits that gender differences in depression prevalence
rates may reflect a tendency for men to underreport depressive symptoms. In this study, we examined aspects of gender role
socialization (gender-related traits, socially desirable responding, beliefs about mental health and depression) that may
contribute to a response bias in self-reports of depression. In addition, we investigated the impact of two contextual variables
(i.e., cause of depression and level of intrusiveness of experimental follow-up) on self-reports of depressive symptoms. Results
indicated that men, but not women, reported fewer depressive symptoms when consent forms indicated that a more involved follow-up
might occur. Further, results indicated differential responding by men and women on measures of gender-related traits, mental
health beliefs, and beliefs about depression and predictors of depressed mood. Together, our results support the assertion
that, in specific contexts, a response bias explanation warrants further consideration in investigations of gender differences
in rates of self-reported depression. 相似文献

The 22q11.2 Deletion Syndrome (DiGeorge/velocardiofacial syndrome) is associated with elevated rates of psychosis, and is also characterized by severe attentional difficulties and executive dysfunction. Behavioral manifestations of this syndrome could result from haploinsufficiency of the catechol-O-methyltransferase (COMT) gene, located within the 22q11 region. The goal of the present study was to examine COMT genotype in relation to behavioral symptomatology in this syndrome. Val158/108Met was genotyped in 38 patients (16 Met/-, 22 Val/-) with confirmed 22q11.2 deletions who had received the Child Behavior Checklist (CBCL) as part of a comprehensive evaluation. Results indicated that the Val genotype was associated with significantly greater internalizing and externalizing behavioral symptomatology in children with 22q11.2 deletions. Val allele status was associated with a greater-than-four-fold increase in risk for clinically significant behavior problems in children with this syndrome. These data are consistent with previous findings of increased psychopathology associated with the Val genotype in normal individuals and suggest that a functional genetic polymorphism in the 22q11 region may influence behavior in individuals with COMT haploinsufficiency. 相似文献

The present study explored variations in online communication and relationship preferences for friends, family, coworkers, and unknown individuals across gender (men, women), age (young, middle, late), and duration of Internet use (low, medium, high). A total of 174 individuals participated in this study. They were divided into two gender (86 men and 88 women), three age (60 young, 60 middle, and 54 late) and three Internet use duration (60 low, 58 medium, and 54 high) groups. All participants completed several questionnaires that assessed online communication and relationship building preferences. Results indicated no significant main effect for gender and online communication and relationship preferences. The main effect for age was significant for online communication with friends and unknown individuals. Young adults indicated their higher preferences for online communication with friends and unknown individuals compared to middle and late adult age groups. The main effect for duration of Internet use was significant for online communication and relationship preferences. High Internet users indicated higher scores on online communication and relationship building, compared to their counterparts. No significant main effects for duration of Internet use were significant on any of the offline characteristics. Implications of these findings and their relevance to mental health issues and organizational environment were discussed. 相似文献
