The relationship among substance abuse counselors' education, experience, recovery status, and cognitive development (conceptual complexity and moral reasoning levels) was examined in a simultaneous multiple regression. Significant relationships were found between counselors' level of conceptual complexity and moral reasoning and their education. Implications for counselor training are presented.  相似文献

Smith-Magenis syndrome (SMS) is a complex disorder characterized by numerous challenges, including intellectual disability, speech delay, decreased pain sensitivity, sleep disturbances, hyperactivity, mood instability, and self-injury. Caregivers must readily adapt to the ever-changing needs of the child. Due to these demands, caregivers may encounter difficulties maintaining their own level of well-being. Thus, a total of 112 primary caregivers (i.e., parents) of individuals diagnosed with SMS responded to online questionnaires to assess demographic and psychosocial factors, such as perceptions of child health vulnerability, benefit finding, sleep behaviors, anxiety and depression symptomatology, and caregiver satisfaction and self-efficacy, which may be related to caregiver well-being. Results show that, among mothers, caregiver well-being was directly related to perceived child health vulnerability, caregiver satisfaction, and benefit finding, and a significant moderating effect was observed for depression/anxiety counseling after beginning the caregiver role on the relationship between anxiety symptomatology and caregiver well-being. Results further suggest that maternal caregivers who report high levels of anxiety but do not seek counseling fair the worst in terms of well-being. Among fathers, lower depression symptoms and greater benefit finding were related to higher levels of caregiver well-being. These data show that many factors play roles in influencing coping and well-being among SMS caregivers. Investigating these variables and relationships may reveal additional resources and interventions to assist primary caregivers.  相似文献

Detection of deception and confirmation of truth telling with conventional polygraphy raised a host of technical and ethical issues. Recently, newer methods of recording electromagnetic signals from the brain show promise in permitting the detection of deception or truth telling. Some are even being promoted as more accurate than conventional polygraphy. While the new technologies raise issues of personal privacy, acceptable forensic application, and other social issues, the focus of this paper is the technical limitations of the developing technology. Those limitations include the measurement validity of the new technologies, which remains largely unknown. Another set of questions pertains to the psychological paradigms used to model or constrain the target behavior. Finally, there is little standardization in the field, and the vulnerability of the techniques to countermeasures is unknown. Premature application of these technologies outside of research settings should be resisted, and the social conversation about the appropriate parameters of its civil, forensic, and security use should begin.  相似文献

Small groups are called upon to make important policy decisions under a wide variety of procedural constraints. ACPE is a flexible, computerized system for conducting small-group voting experiments. It permits researchers to examine the impact of electronic communication on group deliberation and choice. The system runs under a variety of different personal computer networks and is designed to permit the specification of voting rules, communication, and group sizes. The system also facilitates the study of group process by tracking all messages sent and votes taken. An experiment in which the system was used is briefly described.  相似文献

Six hens responded on concurrent variable-interval (key-peck) variable-interval (door-push) schedules of reinforcement in which the second-order (fixed-ratio) requirements on the alternatives (Experiment 1) or the required door forces (Experiment 2) were varied. The key-peck and door-push response (measured as fixed-ratio completion) and time data were well described by the generalized matching law. However, the manipulations of fixed-ratio requirement and required response force differed in their effects. The manipulations of fixed-ratio size affected the response and time measures differently, producing fairly constant, multiplicative biases only in terms of response allocation. It was argued that variations in fixed-ratio size necessarily change the time allocated to that response unit, and thus changes in time bias were not necessarily a fundamental effect of changing the ratio. In contrast, the changes in response bias were a fundamental result of changes in ratio size. The response-force manipulations produced similar bias shifts in terms of response and time allocation, but they appeared to combine with relative reinforcement rate to affect choice interactively. Specifically, behavior appeared to be biased towards the least effortful (i.e., key-peck) response, but the increases in door force had a larger effect on bias when the hens were making this response infrequently (on a lean schedule). The different effects of the fixed-ratio and response-force manipulations on concurrent performance were partially accounted for by the differing times required to complete each response unit under those manipulations, but this would not account for the interaction. The interaction would be consonant with increased response effort decreasing the effective value of the associated reinforcement schedule.  相似文献
