Wanchisen BA 《The Behavior analyst / MABA》1990,13(1):31-37
While a great deal of behavior analytic research has focussed on studying current contingencies, the amount of work done in the area of conditioning history is spotty, at best. Weiner (1964, 1969) conducted history research with human subjects, but little has followed in either the human or the nonhuman literature. Some direction can also be found in the literature studying the effects of conditioning on drug effects (e.g., Barrett, 1977; Urbain, Poling, Millam, & Thompson, 1978). However, "behavioral history" or "conditioning history" has not been a fully-developed area within behavior analysis. It is suggested that empirical work on history effects might have implications for (a) better understanding human-nonhuman behavioral differences and similarities, (b) clinical applications, especially where clients are resistant to behavioral change, and (c) theoretical assumptions in behavior analysis in relation to both basic and applied concerns. 相似文献

Patterns of manual preference and the extent to which preference provided a benefit in performance (movement time) were evaluated in 7 young adult capuchin monkeys (Cebus apella). Directions of preference were inconsistent within individual animals across home-cage activities, unimanual, and bimanual experimental tasks. Preferences were more strongly expressed in the experimental tasks than in the home cage. A left bias in the population for prehension, predicted by recent theories, was not evident in any setting. Movement time was moderately negatively correlated with degree of preference within experimental tasks. The benefit to performance conferred by lateral preference was not dependent on whether the right or left hand was preferred. Lateralization of prehension appears to be a flexible process in these monkeys, which can result in quickly realized benefits in some conditions. 相似文献

Humility training is conceptualized as an appropriate treatment for persons who occasionally describe themselves, but are most frequently described by others as overbearing, insensitive and deceitful. Procedures are outlined to identify unrecognized fears and improve interpersonal skills. Humility is presented as a counterpoint to assertiveness and aggression/anger control interventions. 相似文献

Consecutive counsellor trainee and client statements from 12 audiotaped assessment interviews were coded to operationalize empathy as a sequential variable. For each two statement sequence the speaking order (counsellor to client, client to counsellor) was also coded, and the resultant matrix analyzed via loglinear statistical procedures for categorical data. For the speaking order client to counsellor, three empathy sequences (empathy enhancing, empathy diverging, empathy commencing) were found to be significantly related to counselling effectiveness. For the speaking order counsellor to client, only one sequence(empathy diverging) was found to be significantly related to counselling effectiveness. Implications for counsellor training and future research are discussed. 相似文献

In the last two decades, an important new therapeutic delivery system has been emerging to serve the needs of the American workforce. Known as Employee Assistance Programs (EAPs), these company and community based programs were created to provide mental health services to workers whose job performance is impaired due to substance abuse or other difficulties. Although there are obvious similarities between the mission espoused by EAPs and traditions of the counseling psychology profession, many members of our discipline have only recently become involved in these programs. This paper discusses various reasons why counseling psychologists have not become involved with EAPs. It also presents some ways that counseling psychologists may contribute to these programs and it highlights the similarities in the philosophies and the activities of EAP and counseling psychology practitioners and scientists. Additionally, some suggestions for how to prepare counseling psychologists for entrance into the EAP profession are offered. Finally, a brief research agenda designed to guide counseling psychologists who are interested in the study of EAP related variables is presented.We are appreciative of Karen Novak's and Marilyn Bayer's editorial assistance on this paper. 相似文献

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS).
Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as
cooperative unions and multinational companies are included. After considering the influence of the changing environment on
the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined.
Special attention is given to public and private R&D. The article then looks where information technology (IT) fits in and
what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences
with this strategic investment are evaluated. 相似文献

Hardware and software modifications are presented that allow for collection and recognition by a Commodore computer of spoken responses. Responses are timed with millisecond accuracy and automatically analyzed and scored. Accuracy data for this device from several experiments are presented. Potential applications and suggestions for improving recognition accuracy are also discussed. 相似文献
