Consideration of reinforcer magnitude may be important for maximizing the efficacy of treatment for problem behavior. Nonetheless, relatively little is known about children's preferences for different magnitudes of social reinforcement or the extent to which preference is related to differences in reinforcer efficacy. The purpose of the current study was to evaluate the relations among reinforcer magnitude, preference, and efficacy by drawing on the procedures and results of basic experimentation in this area. Three children who engaged in problem behavior that was maintained by social positive reinforcement (attention, access to tangible items) participated. Results indicated that preference for different magnitudes of social reinforcement may predict reinforcer efficacy and that magnitude effects may be mediated by the schedule requirement. 相似文献

Visual search can benefit when one set of distractors is presented as a preview, prior to the appearance the second set of distractors plus the target (Watson & Humphreys, 1997). It has been shown that changing the shape of the old, previewed stimuli when the new items appear causes the old stimuli to recompete for selection with the new ones. In contrast, changing the luminance or color of the old stimuli has no detrimental effects. Here, we present five experiments that reassessed the effect of luminance changes in preview search. We show (1) that preview search is remarkably resistant to large changes in the absolute luminance of the old stimuli, even when those changes would ordinarily be sufficient to signal the appearance of a new object and draw attention (Experiments 1 and 2), and (2) that resistance to luminance changes can be bolstered by feature-based inhibitory processes (Experiments 3–5). These findings are discussed in terms of the possible ecological properties of time-based visual selection and possible mechanisms underlying the preview benefit. 相似文献

As the United States diversifies, we review research on both the benefits and challenges of diversity in developmental science. Taking a “contact in context” approach, we focus on how structural and interpersonal diversity influence ethnic/racial developmental processes and outcomes from early childhood to adolescence. We also consider how a child’s own ethnicity/race may shape diversity experiences. We offer this review with the ultimate goal of optimizing benefits and minimizing challenges. We offer a “contact in context” conceptual model that integrates diversity at multiple levels, child ethnicity/race, and developmental changes over time. We conclude with recommendations for future research. 相似文献

Although arts‐based programming is shown to positively influence the development of youth exposed to adversity, little is known about the influence these programs have on formerly incarcerated emerging adult Black men enrolled in an alternative school. With educational resilience as a guiding framework, this qualitative case study explored the ways in which an arts‐based program in the context of an alternative school designed for formerly incarcerated young people facilitates emerging adult Black men's academic and social–emotional development. Data collection consisted of observations and interviews with school personnel and formerly incarcerated Black male students. Analysis and interpretation included a range of inductive techniques (coding, constant comparisons, and memoing). Results indicate that offering arts‐based activities fostered an environment where students could build caring and supportive relationships with peers and school personnel. Instructional practices that integrated music and poetry provided meaningful opportunities for the young men to participate, which appeared to enhance their motivation and attitudes (self, others, learning, and school) and academic self‐efficacy, and lessen their psychological and emotional distress. Study findings provide insights into how an arts‐based program in an alternative school can improve healthy development and academic achievement among formerly incarcerated young Black men transitioning into adulthood. 相似文献

While self-report data warrants interpretive caution in applied settings, these indices serve an important role in exploratory research. The Lifetime Assessment of Violent Acts (LAVA) inventory is a brief, reliable, face-valid questionnaire for estimating the frequency, triggers, and consequences (including injuries to others) of prior acts of aggression. The LAVA also identifies the situational contexts in which prior violence was triggered and provides a basis for risk classifications based on past reactive, intimate partner, alcohol-related, and/or weapon-related violence. Scores on the LAVA indices have been linked to a range of developmental and maladjustment indicators. Associations were found between lab-provoked (Taylor Aggression Paradigm) responding and both dimensional and risk classification scores in this sample (N = 92) of college men. Participants “competed” with a fictional opponent using electric shock as a retaliatory measure for perceived provocation. The total LAVA dimensional score predicted mean shock intensity ( d = .87), baseline responding ( d = 0.90), and past sexual aggression ( d = 1.01). Shock intensities in response to high provocation were predicted ( M d = 0.57) by all but one LAVA index. Participants who reported inflicting one or more injuries on another showed more intense escalations of aggression ( d = 0.46) in response to provocation than normative counterparts. Prior injuries to another ( RR = 2.71), reactive acts of aggression ( RR = 3.73), or intimate-partner violence ( RR = 4.19) elevated the risk of one or more prior acts of self-reported sexual aggression. The limitations and potential value of self-report data were discussed in regard to aggression research. 相似文献

Despite the rapidly growing nature of the Mexican American population in the United States, relatively little is known regarding
cognitive aging among this minority group compared to non-Hispanic, white individuals. The current study was conducted to
describe the nature of cognitive and affective characteristics of Mexican American patients with dementia or other cognitive
disorders on initial presentation to a Memory Disorder Clinic. Archival data were reviewed from this specialty clinic for
219 patients who were evaluated for the first time over a 2-year period. Twenty-two Mexican American patients were identified,
and a sample of 22 matched non-Hispanic white patients was derived for comparison. When compared to non-Hispanic white patients,
Mexican Americans were found in fewer numbers, reported higher levels of anxiety and depression, and produced lower scores
on neurocognitive assessments. Results support the notion that Mexican American patients present for cognitive assessment
and treatment at a greater stage of impairment severity as compared to non-Hispanic whites. 相似文献

Inhibitory control and emotion regulation in preschool children 总被引:4,自引:0,他引:4
This research investigated the relation between individual differences in inhibitory control and emotion regulation. Preschool children (N = 53) ages 4–6 (M = 5; 0) were assessed on brief batteries of inhibitory control of prepotent responses and emotion regulation. Individual differences in inhibitory control were significantly correlated with children's ability to regulate their emotions. This relation held up even after controlling for age and verbal ability, and persisted for both Emotion Understanding and “online” control of emotional expressions that were negative (Disappointing Gift) or positive (Secret Keeping). Parent report of children's self-control and emotion regulation corroborated the behavioral results. These findings suggest that executive control of attention, action, and emotion are skills that develop in concert in the preschool period. However, there was also evidence of a quadratic relation in which emotion regulation was optimal at intermediate levels of inhibition, highlighting the interplay of both cognitive control and temperament in socio-emotional functioning. 相似文献

Professional psychology's ability to meet older Americans' psychological needs and to simultaneously thrive as a profession will be closely tied to the federal Medicare program over the coming decades. Despite legislative changes in the 1980s providing professional autonomy to psychologists and expanding coverage for mental health services, Medicare coverage policies, reimbursement mechanisms, and organizational traditions continue to limit older Americans' access to psychological services. This article describes how psychologists can influence Medicare coverage policy. Specifically, the authors examine widely unrecognized policy processes and recent political developments and analyze the recent creation of a new Medicare counseling benefit, applying J. W. Kingdon's (1995) well-known model of policy change. These recent developments offer new opportunities for expanding Medicare coverage of psychological services, particularly in the areas of prevention, screening, and early intervention. The article provides an analysis to guide psychologists in engaging in strategic advocacy and incorporating psychological prevention and early intervention services into Medicare. As Medicare policy entrepreneurs, psychologists can improve the well-being of millions of Americans who rely on the national health insurance program and, in so doing, can help shape the future practice of psychology. 相似文献
