Factors influencing the use of internal summary evaluations versus external information in choice

Decision makers cope with more demanding tasks by shifting their cognitive strategies, balancing effort expenditure against the desire to produce an accurate response. In choice tasks, one method for reducing effort while simultaneously maintaining accuracy is to shift from a reliance on information obtained from the external environment to that retrieved from memory, particularly summary evaluations (i.e. relatively stable evaluative reactions to the overall attractiveness of individual alternatives) acquired from previous decision-making experience. We examined four factors that should all encourage decision makers to rely to some extent on internal summary evaluations rather than external information search: (1) increased external search costs, (2) greater time pressure, (3) increased incentives to make an accurate choice, and (4) increased levels of prior experience with the choice context. Sixty experimental subjects chose their preferred alternative from a set of women's magazines. Decision processes were inferred from verbal protocols, computer-generated search records, and decision times. Only increased external search costs led to a greater reliance on summary evaluations. Although increased time pressure, increased incentives, and increased experience with the context did lead to changes in search and evaluation processes, contrary to initial expectations decision makers did not shift to a greater reliance on summary evaluations. These results suggest that while decision makers do sometimes use summary evaluations as a substitute for external search, this is only one of several mechanisms available for effort reduction. Understanding when and where decision makers rely upon summary evaluations probably requires a broader conceptualization of knowledge structures, particularly a consideration of the knowledge that decision makers possess about different choice strategies and their effectiveness.     

Discrimination and liberal neutrality

This paper examines the political philosophy of Liberalism with particular focus on the principles of liberal neutrality and value pluralism. These principles, which are advocated by the most prominent contemporary liberal theorists mark a significant departure from classical liberalism and its monistic approach to seeking truth and the good. I argue that the shift to neutrality and pluralism have done a disservice to liberalism and that the cultivation of discrimination skills is needed to deal with the complex tasks of making decisions intelligently and effectively.     

A new strategy for studying spatial aptitude

A new approach to testing for and training in spatial aptitude is described. Figurai analogy problem terms from the cognitive abilities test are photodigitized and arrayed in zones on the computer screen; they can be seen only when selected with the mouse (i.e., one at a time). Viewing patterns and durations can then be analyzed to assess problem encoding and solution strategies. Implications are discussed.     

The P & p illusion

Identical letters can appear to differ in size and shape depending on whether they are interpreted as uppercase or lowercase. The effect is most dramatic with the letter p. Examination of subjects’ estimates of the magnitude of the effect for different stimuli suggests that two factors are involved in the illusion. One factor depends only on whether a letter is interpreted as uppercase or lowercase. Thisfactor can be manipulated by changes in the size or case ofthe surrounding letters. The second factor, which depends on the possibility of interpreting a vertical line alternatively as an ascender or a descender(as in p or y), seems to involve a change in the perceived size of the letters’ loops.     

Lay knowledge of eyewitness issues: A Canadian evaluation

Lay opinions concerning eyewitness topics were surveyed in three community samples of juror‐eligible participants in Canada. The scientific reliability of these topics had been previously evaluated by eyewitness experts. The first survey assessed participant responses to the identically worded expert items. Participants responded to many statements with greater accuracy than anticipated. Two subsequent surveys assessed the consistency of lay knowledge across variations in the directionality and wording of items and the provision of additional contextual information. Taken together, jury‐eligible participants frequently responded to survey items in ways that closely resembled the responses of experts and suggested awareness and understanding of these topics at levels beyond those previously obtained. Further, the provision of contextual information increased response accuracy and reduced the frequencies of ‘Don't Know’ responses. Deficiencies in knowledge for 50% of the topics were also apparent; however, these topics were frequently those for which the experts themselves had not reached consensus.

Empirically Documenting Clinically Significant Change in Rational Emotive Behavior Therapy

The purpose of the present article is to outline the conceptual foundation and practical methodology of the Jacobson-Truax Clinically Significant Change index, derived from psychotherapy outcome research. This way of considering what constitutes clinically significant change in psychotherapy puts a premium on social validation. It empowers clinicians to evaluate the meaningfulness of their client's progress and to communicate that progress to third parties such as other clinicians, researchers, and insurers. Application of the method is demonstrated in the case of a client treated with Rational Emotive Behavior Therapy (REBT). The discussion focuses on the advantages of this procedure for satisfying the intellectual interest of the practitioner-scientist and for furthering informed discussion of the value in various applications of REBT to clinical problems.     

Discerning the Spirit among Catholic Charismatics

The “Catholic Charismatic Renewal,” renamed by the bishops the “Charismatic Renewal of the Church,” has a 35 year history in the US and Europe. Debated at Vatican II and analyzed by theologians, the experience of spiritual charisms requires thoughtful discernment, especially if charism is to be properly integrated with sacrament.

Understanding the social emotional practices of therapists

Emotions are central to the therapy process and skilful use by therapists of client emotion is an essential catalyst to client change. However, the contribution of emotion to the therapy process and how therapists’ social emotional skills are incorporated into psychological practice is still unclear. Using a statistical method for mapping psychological constructs, therapists’ social emotional skills were transformed into a “map” with three spatial dimensions, which was supported by comparative reliability checks. The nature of social emotional skills was further investigated by administering a Q-Sort of emotional practice items to 47 therapists. Ten highly applicable clusters of social emotional skills across seven style patterns with therapists were identified. Tentative links were drawn between demographic data and both clusters and therapist styles. These findings suggest therapists’ social emotional skills can be organised into meaningful clusters and that therapists can be styled according to their responses across these clusters. Furthermore, gaps identified in the model suggest possible “blind spots” in the literature. The implications of these findings are significant for training and practice.     

Preventing HIV infection among injecting drug users: Intuitive and counter-intuitive findings

The disease now called AIDS was first reported among injecting drug users in 1981. This article reviews the last 15 years of research on preventing HIV infection and AIDS among injecting drug users. Many of the findings were surprising in the context of previous understandings of the illicit injection of psychoactive drugs—both with respect to the much-larger-than-expected size of the epidemic and the much-greater-than-expected potential for behavior change among drug injectors (IDU). The research is reviewed within a framework of eight issues: the importance of the problem in the United States, the global diffusion of injecting drug use, the global diffusion of HIV among IDUs, potential rapid spread of HIV among IDUs, risk reduction among IDUs, community-level prevention, syringe exchange programs, and developing a public-health perspective on psychoactive drug use.
