The purpose of this paper is to outline the challenges of psychological research in addressing the mechanisms of emergence: how new behavioral patterns and cognitive abilities arise from the interaction of an organism with its environment in real time. We review some of the empirical studies on infant development with reference to Dynamical Systems accounts and relevant views such as the ecological approach to perception and action, and cover topics ranging from early motor skills to goal‐directed locomotion and to higher cognitive development. The central claim is that the results of these studies are essentially related: they suggest that there is a fundamental connection among perception, motor behavior, and cognition. In addition, we recount our attempt to re‐enact the situatedness and temporal structure of the decision‐making processes of human infants by using an autonomous robotic device. We conclude by highlighting several insights from the broad spectrum of studies looking into the embodied nature of adaptive behavior. In our view, such studies are making a profound contribution to uncovering the emergent mechanisms of intellectual and bodily activity throughout development.  相似文献

This paper uses concepts from social networks and social exchange theories to describe the implementation of evidence-based practices in afterschool programs. The members of the LEGACY Together Afterschool Project team have been involved in conducting collaborative research to migrate a behavioral strategy that has been documented to reduce disruptive behaviors in classroom settings to a new setting—that of afterschool programs. We adapted the Paxis Institute’s version of the Good Behavior Game to afterschool settings which differ from in-school settings, including more fluid attendance, multiple age groupings, diverse activities that may take place simultaneously, and differences in staff training and experience (Barrish et al. in J Appl Behav Anal 2(2):119–124, 1969; Embry et al. in The Pax Good Behavior Game. Hazelden, Center City, 2003; Hynes et al. in J Child Serv 4(3):4–20, 2009; Kellam et al. in Drug Alcohol Depend 95:S5–S28, 2008; Tingstrom et al. in Behav Modif 30(2):225–253, 2006). This paper presents the experiences of the three adult groups involved in the implementation process who give first-person accounts of implementation: (1) university-based scientist-practitioners, (2) community partners who trained and provided technical assistance/coaching, and (3) an afterschool program administrator. We introduce here the AIMS model used to frame the implementation process conceptualized by this town–gown collaborative team. AIMS builds upon previous work in implementation science using four phases in which the three collaborators have overlapping roles: approach/engagement, implementation, monitoring, and sustainability. Within all four phases principles of Social Exchange Theory and Social Network Theory are highlighted.  相似文献

This qualitative study examined the influence of service-learning on the development of Students' feelings of civic responsibility while involved with a community-based organization. Occupational therapy students involved in a semester-long service-learning experience maintained weekly reflective journals. Six such reflective journals were randomly selected for analysis. Findings revealed that while engaged in service-learning the six participants voiced themes of increased self-awareness, awareness of homeless individuals as persons, awareness of social issues, and professional self-efficacy. These developing competencies are associated with the skills required for health care professionals to participate in civic engagement and client advocacy.  相似文献

The effects of attention-deficit/hyperactivity disorder (ADHD) symptoms on the psychosocial functioning of Hispanic youth have been understudied. It also remains unclear if the well-established associations between ADHD symptoms and academic and social impairment are exacerbated by co-occurring internalizing symptoms. The purposes of the present study were to (1) examine whether ADHD symptoms would be associated with academic and social problems while also controlling for oppositional defiant disorder (ODD) symptoms, and (2) test the hypothesis that anxious and depressive symptoms would moderate the relations between ADHD symptoms and academic and social problems. Participants were 142 at-risk Hispanic adolescents (54 % male, ages 14–19) who reported on their anxious and depressive symptoms, as well as their teachers who reported on adolescents’ ADHD symptoms, ODD symptoms, academic problems, and social problems. When the psychopathology variables were included simultaneously in a path model, ADHD was the only domain significantly positively associated with academic problems. In contrast, ODD and depressive symptoms were the only domains significantly positively associated with social problems when all of the psychopathology variables were included in the path model. No moderation effects were found in relation to academic problems, although a significant ADHD × depression interaction was found in relation to social problems. Specifically, ADHD symptoms were not associated with social problems among adolescents who reported low levels of depressive symptoms, but the association between ADHD symptoms and social problems was significant at higher levels of depression. In addition to targeting oppositionality, attending to the combined presence of ADHD and depressive symptoms will be important for reducing the social impairments among Hispanic adolescents.  相似文献

Aims: Patients who are referred more than once to a Primary Care Mental Health Improving Access to Psychological Therapies (IAPT) Service raise questions about those patients' clinical characteristics, the appropriateness of the interventions offered and their capacity to make use of them. IAPT treatments are based on National Institute for Health and Clinical Excellence (NICE) guidelines for the treatment of common mental health problems. NICE recommendations are based on evidence gained from clinical trials, in particular Randomised Controlled Trials (RCTs), which tend to exclude the sort of patient with complex and co‐morbid conditions who often present in practice. Method: Using data routinely collected from the IAPTus clinical database, re‐referral patterns and level of complexity of 50 patients who were referred on more than one occasion to a Primary Care Mental Health (Improving Access to Psychological Therapies) Team from 2009–2010, were analysed. Results: The evidence presented in this study indicates patients who re‐refer exhibit complex environmental, historical and psychological problems. Implications for practice: Although further research is required to compare the characteristics of this patient group with those who are referred only once, this study provides limited evidence that such patients may be more likely to engage and complete treatments that offer regular, structured and one‐to‐one interventions.  相似文献

A survey of 345 undergraduate business students from a medium-sized southeastern regional university and 164 undergraduates from a medium-sized university in the United Arab Emirates found that 71 % of all respondents admitted to academic misconduct in a recent 1-year period, a percentage similar to McCabe’s (2005) finding that an average of 70 % of undergraduate students admitted to recent academic misconduct. Business students from the Middle East were significantly less likely to perceive various academic misconduct behaviors as forms of serious cheating compared to business students from the US. Hofstede’s (2001) cultural dimension of individualism/collectivism and Ajzen’s (Organizational Behavior and Human Decision Processes 50, 179–211, 1991) theory of planned behavior are discussed as likely explanations of reported academic misconduct differences between the two countries.  相似文献

This paper contends that principles of virtue ethics have the potential to both supplement and complement academic integrity policy in the adjudication of undergraduate student academic integrity breaches. The paper uses elements of grounded theory to explore responses from 15 Academic Integrity Breach Decision Makers (AIBDMs) at an Australian university, and in particular, the process they use to determine outcomes for student breaches of academic integrity. The findings indicate that AIBDMs often use principles of virtue ethics to help provide nuanced judgement on sometimes complicated breaches of ethical behaviour. The findings demonstrate that many AIBDMs supplemented their knowledge of institutional academic integrity policy with a deep commitment to their own virtuous behaviour.  相似文献

Prior research evaluating health-related quality of life (HRQOL) among pediatric patients with internal cardiac devices has primarily focused on children with cardiac defibrillators, with scant attention devoted to pacemaker recipients. Social support has been conceptualized as a protective factor that partially accounts for differences in HRQOL. This study compares the HRQOL of children with pacemakers with that of healthy children, and examines associations between HRQOL and social support. Twenty-seven pediatric pacemaker recipients completed measures of HRQOL and social support. Their parents also completed measures of child HRQOL. High concordance was found for child and parent-proxy reports of child HRQOL. Children with pacemakers and their parents both reported relatively low child HRQOL when compared to published normative data for healthy children and parents of healthy children. Family and friends emerged as the sources of support positively associated with the greatest number of HRQOL domains. In conclusion, these findings suggest that pediatric pacemaker recipients experience lower levels of HRQOL compared to healthy peers, and that social support from those closest to the child is associated with their perceived HRQOL.  相似文献
