This study evaluated two approaches directed towards enhancing social skills in groups of first and third grade children. In the behavioral intervention, following collection of baseline data, triads of first and third grade children were taught one of four social skills—either touching, asking questions, sharing or praising. The behavioral intervention consisted of instructions, modeling, behavioral rehearsal, feedback and reinforcement. While increases in social behaviors were noted, follow-up indicated substantial erosion in gains. In the ecological intervention, dramatic increases in sharing were noted for an isolate child after being placed in a group whose members displayed high levels of sharing. The differential effectiveness of behavioral versus ecological approaches in establishing and maintaining behaviors are discussed. 相似文献

This paper asks for legislation that will remove criminal sanctions from good faith decisions by parents and physicians to allow severely defective newborns to die. In so doing it attempts to bring to satisfactory resolution conflicting points of view in the disciplines of moral philosophy, medicine, and law. This paper argues that euthanasia of severely defective newborns is morally justifiable and legally permissible within reasonable extensions of current interpretations of the Federal Constitution by the Supreme Court. It describes the medical dilemma, evaluates the moral issues involved, and delineates possible legal alternatives. 相似文献

Denton and McIntyre (1978), using a forced-choice letterrecognition procedure, demonstrated increasing reductions in the spans of apprehension of hyperactive as compared to normal boys when a signal letter was embedded within an increasing number of noise letters. In the present study, the effect of variations in the amount of physical signal-noise similarity and noise redundancy upon the spans of apprehension of hyperactive and normal boys was compared to determine whether noise letters act as more potent distractors for the hyperactive boys. Results indicated the spans of both groups were effected equivalently by variations in signal-noise similarity and noise redundancy. No evidence for a distractibility explanation was obtained. 相似文献

Psychological maltreatment may be the most common form of abuse suffered by North American children within the family environment. However, little effort has been directed towards eliminating and preventing it. The present article emphasizes the importance of thoroughly understanding the phenomenon so that effective intervention strategies can be developed. North American research studies of child maltreatment are reviewed and discussed with particular emphasis placed upon the manifestations of psychological maltreatment, the scope and the consequences of the problem, and the identification of associated risk factors. The paper identifies several areas for improvement before successful interventions can be conceptualized. 相似文献

It has been claimed (V. Coltheart, Laxon, Rickard, & Elton, 1988) that learners as well as skilled readers use phonology for multiple functions in reading-for-meaning tasks. This claim was examined using lexical decision and sentence evaluation tasks. It was found in the first experiment that the type of instruction learners had received determined whether there was prelexical use of phonology in responding to items out of sentence context. Type of instruction had no effect when the items were in context. In the second experiment, performances on a homophone sentence evaluation task and a homophone semantic decision task, which excluded sentence processing, were examined. The results suggest that phonology served the function of access to lexical meanings in addition to any function in postlexical sentence processing. The obtained relationships between relative frequencies of the presented and unpresented homophone mates and item accuracy on these tasks were inconsistent with exclusive use of “direct access” but consistent with access of lexical meanings via phonology and application of a “spelling-check” procedure when multiple homophonic meanings are activated. 相似文献

Collective efficacy is the extension of Bandura's (1977) self-efficacy concept to groups (Bandura, 1982, 1986). Self-efficacy refers to judgments that people make about their personal or individual competency. Collective efficacy concerns judgments that people make about a group's level of competency. This paper contributes to the theory and measurement of collective efficacy and to an understanding of its relationship to self-efficacy and performance. Elementary school teachers' collective- and self-efficacy were measured. The academic domain is well suited to the study of collective-efficacy because the organizational units (schools) all perform the same function (education). The findings supported the hypothesis that, in at least some domains, self-efficacy and collective-efficacy are related but independent constructs. As hypothesized, it was also found that the socioeconomic composition of a school's student body, was a strong predictor of teachers' collective-efficacy. Although teachers' collective-efficacy was associated with school level achievement, this relationship was no longer significant when prior achievement levels were controlled. It was suggested that future research should examine individual behaviors, attitudes, and beliefs that might serve as mediators between efficacy and performance. It was also suggested that the relationship between collective efficacy and organizational culture should be explored. 相似文献

This study's first objective was to apply Ajzen's theory of planned behavior (TPB) in the context of automobile child restraint device use to identify determinants of that behavior. A second objective was to test two specific hypotheses regarding the predictive role of perceived behavioral control: (a) Its inclusion should increase the proportion of variance already explained in intention by the attitudinal and normative components included in the theory of reasoned action; and (b) given the behavior under study, a model in which perception of behavioral control's influence on behavior is entirely mediated by intention, should fit the data. Subjects (N= 590) were parents driving with their 3- to 5-year-old children intercepted while entering or leaving parking lots of different public settings. The behavior of interest, child restraint device use, was rated by two independent observers. A self-report questionnaire assessing all constructs of Ajzen's model was given to the parent, who was instructed to return it by mail. Data were analyzed using LISREL VII. Results showed that perceived behavioral control and, to a lesser extent, attitude, emerged as the main determinants of behavioral intention which was itself predictive of child restraint device use. In addition, both hypotheses regarding the relation between perceived behavioral control on the one hand and intention and behavior, on the other, were supported. Discussion centered first on the mechanism through which perceived behavioral control exerts its influence, and second on the implications of the present results for the theory of reasoned action as well as for the theory of planned behavior. 相似文献

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types. Four children with autism were presented with both reinforced training trials and nonreinforced probe trials of models from vocal, toy-play, and pantomime response types. The probe trials were used to examine generalization within each response type. A multiple baseline design was used to analyze percentage of matching and nonmatching responses to models across response types. This study, the first to analyze imitative response classes in children with autism, showed that imitation generalized from reinforced training models to nonreinforced probe models within a response type, but it did not generalize across response types. Thus, functional response classes determined by topographical boundaries were exhibited within generalized imitation. 相似文献
