Two experiments showed that 2.5‐year‐olds, as well as older children, interpret new verbs in accord with their number of arguments. When interpreting new verbs describing the same motion events, children who heard transitive sentences were more likely than were children who heard intransitive sentences to assume that the verb referred to the actions of the causal agent. The sentences were designed so that only the number of noun‐phrase arguments differed across conditions (e.g. She’s pilking her over there versus She’s pilking over there). These experiments isolate number of noun‐phrase arguments (or number of nouns) as an early constraint on sentence interpretation and verb learning, and provide strong evidence that children as young as 2.5 years of age attend to a sentence’s overall structure in interpreting it.  相似文献

Over the last 30 years, the practice of White American parents adopting African American children has been the focus of much deliberation and commentary. In this article, the authors illuminate relevant literature and research regarding transracial adoption. Counseling and legal implications are also discussed.  相似文献

Our longitudinal field study investigated the relationship between team potency and team effectiveness. The sample for this study was drawn from 71 change management teams from an automotive firm in the USA. Team potency ratings were obtained from team members. Team effectiveness ratings were obtained from team members, team leaders and external raters. Results indicated that team effectiveness and team potency are reciprocally and longitudinally related (p< .01).  相似文献

The authors present (a) an overview of the recent literature on social advocacy, (b) results of a deconstructive analysis of the philosophical and theoretical underpinnings of this movement, (c) a critical analysis of its role and function in the profession, and (d) a call to the profession. The deconstructive analysis revealed 2 major driving forces and 5 related trends; the critical analysis revealed 9 key areas of consideration. Implications and recommendations are presented.  相似文献

There is evidence suggesting aggression may be a positive reinforcer in many species. However, only a few studies have examined the characteristics of aggression as a positive reinforcer in mice. Four types of reinforcement schedules were examined in the current experiment using male Swiss CFW albino mice in a resident—intruder model of aggression as a positive reinforcer. A nose poke response on an operant conditioning panel was reinforced under fixed‐ratio (FR 8), fixed‐interval (FI 5‐min), progressive ratio (PR 2), or differential reinforcement of low rate behavior reinforcement schedules (DRL 40‐s and DRL 80‐s). In the FR conditions, nose pokes were maintained by aggression and extinguished when the aggression contingency was removed. There were long postreinforcement pauses followed by bursts of responses with short interresponse times (IRTs). In the FI conditions, nose pokes were maintained by aggression, occurred more frequently as the interval elapsed, and extinguished when the contingency was removed. In the PR conditions, nose pokes were maintained by aggression, postreinforcement pauses increased as the ratio requirement increased, and responding was extinguished when the aggression contingency was removed. In the DRL conditions, the nose poke rate decreased, while the proportional distributions of IRTs and postreinforcement pauses shifted toward longer durations as the DRL interval increased. However, most responses occurred before the minimum IRT interval elapsed, suggesting weak temporal control of behavior. Overall, the findings suggest aggression can be a positive reinforcer for nose poke responses in mice on ratio‐ and time‐based reinforcement schedules.  相似文献

The absence of validated U.S. rates of nonfatal suicidal behavior places risk management and injury prevention programs at danger of being poorly informed and inadequately conceptualized. In this study we compare estimated rates of intentional self-harm from two ongoing surveys (National Electronic Injury Surveillance System-All Injury Program-NEISS-AIP; National Hospital Ambulatory Medical Care Survey-NHAMCS) to data from the Toxic Exposure Surveillance System. Results suggest that, for every 2002-2003 suicide, there were 12 (NEISSAIP) or 15 (NHAMCS) self-harm-related emergency department visits, and for every intentional self-poisoning death there were 33 intentional overdoses reported to poison control centers, of which two ultimately went untreated.  相似文献

Anger at unfair treatment has been called moral outrage. However, moral outrage—anger at the violation of a moral standard—should be distinguished from personal anger at being harmed and empathic anger at seeing another for whom one cares harmed. Across a preliminary experiment and a main experiment, both designed to manipulate the appraisal conditions for these three forms of anger, we found evidence of personal anger and empathic anger, but little evidence of moral outrage. Participants perceived unfair treatment of another, even another for whom they had not been induced to feel empathy, to be as unfair as participants perceived unfair treatment of themselves. But the appraisal conditions that evoked anger were unfair treatment of self and unfair treatment of a cared-for other, not unfairness per se. In the absence of empathic concern, unfair treatment of another evoked little anger. Possible implications for understanding moral emotion and moral motivation are suggested.

Previous studies have shown that presession attention for problem behavior can serve as an abolishing operation when attention functions as a positive reinforcer. In the current study, we show that the stereotypy of a child with severe disabilities was undifferentiated during standard analogue functional analysis conditions. However, when noncontingent presession attention was provided, stereotypy occurred for social attention as a positive reinforcer, suggesting that the antecedent manipulation functioned as an establishing operation.  相似文献

The present study evaluated the effectiveness of the Positive Parenting Program (Triple P) with a sample of Chinese parents of children with early onset conduct-related problems in Hong Kong. The participants consisted of 91 parents whose children attended maternal and child health centers and child assessment centers for service, and were between three to seven years old. Participants were randomly assigned to the intervention (TP) and a waitlist control group (WL). There was no significant difference in pre-intervention measures between the two groups. However, at post intervention, participants in the TP group reported significantly lower levels of child behavior problems, lower dysfunctional parenting styles, and higher parent sense of competence, compared to the WL group. Implications of these findings for the use of Triple P with families of Chinese descent are discussed.  相似文献
