We investigated whether crawling versus noncrawling infants interpret an agent's movements around an obstacle as goal‐directed. Infants (6–9 months) were habituated to a self‐propelled circle jumping over an obstacle to reach a goal. When the obstacle was removed, infants who crawled (= 13) showed longer looking time to the familiar but now nonrational jumping path versus a novel but rational straight‐line path. Noncrawlers (= 17) did not discriminate. Looking preference was independent of age and speed of habituation. These findings support the claim that infants’ processing of agency emerges early and applies to all agents, but stress the role of experience in the development of action interpretation.  相似文献

Children with attention‐deficit/hyperactivity disorder (ADHD) exhibit marked difficulty with frequent and intense shifts in negative or positive emotions, referred to as emotional lability. This study examines the relationships between negative emotional lability (NEL), ADHD, and reactive and proactive aggression. A community sample of 96 children (53 with ADHD, 43 control) ages 8–12 and their parents completed a baseline session include a diagnostic structured interview and the Reactive–Proactive Aggression Questionnaire (RPAQ). Parents then rated their child's NEL using the Positive and Negative Affect Scale as part of an Ecological Momentary Assessment protocol 3 times a day for 28 days. Seventy‐three participants (37 with ADHD, 36 control) completed the RPAQ at follow‐up. Hierarchical regression analyses indicated that NEL significantly and independently estimates reactive aggression at baseline and follow‐up, regardless of ADHD status. NEL and ADHD status significantly estimates concurrent proactive aggression, but not at follow‐up. Results of this study suggest that NEL accounts for a significant amount of the variability in reactive aggression, a common difficulty in children with ADHD. Further, individuals that are reportedly emotionally labile become more reactively aggressive over time. Both ADHD diagnostic and NEL are predictors of proactive aggression at baseline, although no interaction occurred.  相似文献

Play therapy and filial therapy show promise as effective ways to provide direct services to Head Start, addressing the needs of the children, the families, and the Head Start teachers and staff. This paper examines the utility of play and filial therapies for the Head Start population, presents a systemic explanation for the benefit of filial therapy, and provides a case example for illustration.  相似文献

Other researchers have posited that important events in men's lives-such as employment, marriage, and parenthood-strengthen their social ties and lead them to refrain from crime. A challenge in empirically testing this hypothesis has been the issue of self-selection into life transitions. This study contributes to this literature by estimating the effects of an exogenous life shock on crime. We use data from the Fragile Families and Child Wellbeing Study, augmented with information from hospital medical records, to estimate the effects of the birth of a child with a severe health problem on the likelihood that the infant's father engages in illegal activities. We conduct a number of auxiliary analyses to examine exogeneity assumptions. We find that having an infant born with a severe health condition increases the likelihood that the father is convicted of a crime in the three-year period following the birth of the child, and at least part of the effect appears to operate through work and changes in parental relationships. These results provide evidence that life events can cause crime and, as such, support the "turning point" hypothesis.  相似文献

The Family Group Conference (FGC) is grounded in a rights-based framework, whereby children and their families have the right and responsibility to be primary decision-makers when child protection issues arise, and the statutory agency has the responsibility to convene the entitled members of the family network to lead the decision-making. A distinct core component of FGC—private family time (PFT)—allows families to discuss the information and formulate their responses and plans privately during conferencing. This paper describes how a large child welfare agency in the United States adapted PFT in two ways: (1) including a parent advocate (PA) and (2) abbreviating the amount of time allowed for this discussion. Given the lack of empirical research on the PFT component, this qualitative exploratory study sought to understand the functions and perceived impacts of PA-supported PFT during initial child protective services (CPS) conferences at which decisions of child removal or placement were being contemplated. PFT served multiple beneficial functions and impacted families in several positive ways: families gained greater awareness of safety concerns, felt empowered and confident in the preferred safety and service plan, became increasingly engaged and involved in the case decision-making process and ultimately felt less apprehensive.  相似文献

Pathways to bystander responses were examined in both generalized and bias-based bullying incidents involving immigrant-origin victims. Participants were 168 (Mage = 14.54, 57% female) adolescents of immigrant (37.5%) and nonimmigrant backgrounds, who responded to their likelihood of intervening on behalf of either an Arab or Latine victim. Models tested whether contact with immigrants and one's desires for social contact with immigrant-origin peers mediated the effects of individual (shared immigrant background, and discriminatory tendencies) and situational (inclusive peer norms) intergroup factors on active bystander responses. Findings indicated that desires for social contact reliably mediated effects across both victims; however, contact with immigrant peers was only associated with responses to Latine victims. Implications for how to promote bystander intervention are discussed.  相似文献

An exploratory qualitative study was conducted to explore how child welfare administrators use research evidence in decision-making. Content analysis revealed that a cultural shift toward evidence-based practice (EBP) is occurring in Canadian child welfare organizations and multiple types of evidence inform policy decisions. Barriers to using evidence include individual, organizational, and environmental factors. Facilitating factors include the development of internal champions and organizational cultures that value EBP. Integrating research into practice and policy decisions requires a multifaceted approach of creating organizational cultures that support research utilization and supporting senior bureaucrats to use research evidence in policy development.  相似文献

This article examines one issue in how public relations students are socialized in their understanding of the value and power of social media in the practice of public relations. The public relations academic research about social media is explored, as well as the professional claims about the value of social media as a public relations tactic. The researchers conducted a content analysis of 1 year of Public Relations Tactics issues. The data are viewed through the theoretical frame of the socialization literature ( Jablin, 1987). The results suggest that claims of social media power far outweigh evidence of social media effectiveness as a communication tool. A disconnect exists between what authors of Public Relations Tactics pieces view as the potential for social media and the research findings about the effectiveness of social media. The final section of the article discusses the implications for public relations educators, professional associations, and practitioners as they consider social media tactics in public relations strategy.  相似文献

Results of a survey sent to members of the editorial boards of five behavior-analytic journals in 1990 indicated that there was no consensus among respondents with respect to whether delayed events can function as reinforcers (Schlinger, Blakely, Fillhard, & Poling, 1991). Since that time, several studies with nonhuman animals have demonstrated that events delayed by at least several seconds can increase the probability of occurrence of the responses that produce them. To determine the relative number of contemporary behavior analysts who nonetheless believe that reinforcers must immediately follow the responses that produce them, the present study replicated the procedures used by Schlinger et al., with similar results. That is, respondents did not agree with respect to whether delayed events could be reinforcers.  相似文献
