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

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

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

Stigma surrounding major mental illness creates many barriers. People who experience mental illness face discrimination and prejudice when renting homes, applying for jobs, and accessing mental health services. The authors review the current literature regarding stigma and mental illness. They define stigma and review theories that explain its impact. Counselor training is a peak time to identify and begin to mitigate stigma related to people with mental illness. Implications for counselor training are addressed. 相似文献

Numerous stereotypes exist regarding race and gender, and while all are difficult to eradicate, one still regnant throughout
society is the notion that females are not as capable as males within the fields of math and science. In order to expose this
belief as faulty, an in depth literature review was initiated, with special attention being placed on interventions considered
helpful in eliminating stereotype threat. The paper’s primary purpose centered on how, and to what extent, stereotype threats
affect the mathematics scores of females and minorities. In addition, case studies and a critical perspective regarding the
research, as well as suggestions for future research, are discussed. 相似文献

Researchers have demonstrated that a person's rhythmic movements can become unintentionally entrained to another person's rhythmic movements or an environmental event. There are indications, however, that in both cases the likelihood of entrainment depends on the difference between the uncoupled periods of the two rhythms. The authors examined the range of period differences over which unintentional visual coordination might occur in 16 participants (Experiment 1) and 15 participants (Experiment 2). Cross-spectral coherence analysis and the distribution of continuous relative phase revealed that visual entrainment decreased as the difference between participants' preferred period and the experimenter-determined period of the environmental stimulus increased. The present findings extend the dynamical systems perspective on person-environment coupling and highlight the significance of period difference to the emergence of unintentional coordination. 相似文献

In this study we compared adolescent mothers and the fathers of their infants to examine levels of and predictors of parenting satisfaction. Participants were 41 adolescent mothers who were contacted through alternative school programs and the fathers of their infants. Not all of the fathers were adolescents. The sample was racially diverse (White, Black, Native American, and Hispanic). Correlation and t test analyses were conducted and those variables that were significantly correlated with parenting satisfaction were used in regression analyses. Mothers' parenting satisfaction and paternal control scores were higher than fathers' scores. Self-esteem, age at the baby's birth, and social support satisfaction significantly predicted parenting satisfaction for fathers, whereas only self-esteem and social support satisfaction did so for mothers. 相似文献
