This study identified stable components of Type A behavior as usually defined, and examined their relationships with more traditional psychological constructs. Overall scores on the most popular Type A measure (a version of the Jenkins Activity Survey) were moderately associated with ambition but largely unrelated to measures of adjustment. An item analysis yielded subcomponents of Drivenness and Involvement. Drivenness was unrelated to ambition, but was positively related to anxiety and negatively related to interpersonal perceptiveness. Involvement was positively related to ambition and to interpersonal competence. It is suggested that the Jenkins Activity Survey measures a heterogeneous mixture of constructive commitment and self-defeating responses that clouds its psychological interpretation.  相似文献

70 mentally retarded students, successfully taught to conserve number and substance in the Piagetian sense, resisted attempts at extinction but were unable to generalize to other conservation tasks.  相似文献

Interactional competencies that develop in the first two years of life provide a foundation for all further social and communicative developments. Their normal acquisition, especially in the handicapped, can not be taken for granted. If delays in social-communicative development can be identified early in life and changes made in how the social environment interacts with the child, intervention may effectively facilitate social development. However, to accomplish this, both a model for describing and an instrument for assessing interactional competencies are needed. A recently developed set of scales, organized according to a cognitive-developmental framework and drawing upon recent research literature, is described in terms of its organization and content. Results that support the cognitive model underlying the set of scales are reported. The paper concludes with a consideration of potential criticisms that may apply to such a theoretically based instrument.  相似文献

This study compared contingent and noncontingent access to therapy dogs during educational tasks for children with autism spectrum disorder using a multielement design. The experimenters assessed whether initial preference for the dog predicted reinforcer efficacy and how preference changed across time. A higher response rate during contingent dog sessions than baseline sessions occurred for 4 out of 5 participants, suggesting that the dog functioned as a reinforcer. One participant engaged in a high rate of responding in both contingent and noncontingent dog conditions. Preference assessments revealed idiosyncrasies, suggesting that further research is needed into the predictive nature of initial preference assessments with animals as part of the stimulus array. The experimenters also analyzed salivary cortisol before and after sessions to determine if learning about the upcoming interaction with a dog reduced salivary cortisol in children. Cortisol was variable across participants, with only some deriving a potential physiological benefit from expecting to interact with the dog.  相似文献

Quantitative models of resurgence (e.g., Behavioral Momentum Theory, Resurgence as Choice) suggest that resurgence is partly a function of the duration of extinction exposure, with longer histories of extinction producing less resurgence. This prediction is supported by some laboratory research and has been partially supported by clinical translations that did not isolate the effects of extinction exposure prior to testing for resurgence. The degree to which different histories of extinction impact the likelihood of treatment relapse in therapeutic applications of differential reinforcement is of great interest to the clinical community, including insurance carriers and other financial providers. In the present study, we isolated the effects of extinction history for severe destructive behavior across 6 participants referred for treatment services and examined resurgence of destructive behavior when alternative reinforcement terminated. Our within-subject evaluation showed no difference in the level of resurgence or persistence of destructive behavior following short and long exposures to differential reinforcement with extinction. We discuss our failure to replicate in relation to experimental-design considerations for investigating this and other relapse phenomena in future research with clinical populations.  相似文献

Medicalization is the process by which conditions, for example, intellectual disability, hyperactivity in children, and posttraumatic stress disorder, become understood as medical disorders. During this process, the medical community often collectively assigns a label to a condition and consequently to those who would be said to have the disorder. We argue that there are at least two previously overlooked ways in which this linguistic practice may be wrongful, and sometimes, unjust: first, when the initial introduction of a medical label is done without the participation of those individuals who are being labelled, and second, when attempts by those individuals to renegotiate the labels are thwarted or otherwise rendered ineffective. In both cases, we argue, individuals are unfairly excluded from a linguistic practice that would be valuable for them to participate in. Furthermore, we argue that their exclusion depends in part on the authority of the medical institution to ignore their demands for participation. In making this case, we will propose the more general claim that participating in the linguistic processes of determining and renegotiating the words that will be used to describe oneself is an exercise of linguistic agency, a capacity that has both instrumental and intrinsic value.  相似文献
