Preserved organization of semantic attributes in Alzheimer's disease

This study investigated whether Alzheimer's disease (AD) disrupts the basic organization of the semantic attributes of concepts. Young and normal older subjects and AD patients were presented with a target concept followed by a stimulus word and were to decide whether the stimulus was related to the target. On those trials where it was, the stimulus was either a high-, medium-, or low-dominance attribute of the target. The higher the normative dominance, the more important the attribute to concept meaning. In all 3 subject groups, decision time varied as a function of dominance. The higher the dominance, the faster the decision. Attribute dominance affected the performance of AD patients more than that of normal subjects. These results suggest that AD patients retain their knowledge of the relative importance that the different attributes of a concept have for concept meaning.     

Effects of decision strategy and number of openings on employment selection decisions

The purpose of this study was to explore the impact of two factors—decision strategy and the number of openings—on selection decisions. Two hundred graduate and undergraduate students participated in a human resource employment screening simulation. Decision strategy was varied by having candidates evaluate resumes and letters of application for 20 candidates one-at-a-time (sequentially) or all at once (simultaneously). The number of position openings was either one or three. Decision strategy affected the number of candidates accepted, acceptance threshold, and decision time. The number of openings affected selection decisions in the simultaneous but not the sequential context. Implications of these results for selection processes are discussed.     

Forgetting the lessons of history

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.     

Improvisational therapy: Evolving one's own clinical style

This article offers an invitation to develop one's own unique clinical style, relying less on institutionalized schools of therapy and more on the therapist's own natural resources. An emphasis is placed upon understanding therapy as art, trusting one's imagination, and maintaining a healthy irreverence for professional politics.     

Poverty,state, and the family: A challenge for family therapy

Much family therapy writing has focused on work with discrete presenting problems in circumscribed clinical practice settings. This paper takes a broader focus of poor families which do not fit easily into the one-hour therapy schedule, in the context of the powerful forces of politics and economics. If the prevailing political attitudes and economic realities are ignored, direct practice with families may fail to meet them at their point of experience. Examples of political views, and therapeutic and research thinking which do not pay attention to these aspects, are used to highlight the author's point of view.
