Intuition and the socratic method: Two opposed ways of knowing?

Socratic method and intuition are two ways of knowing commonly thought as opposed. The author shows how both ways of knowing can be linked in an education that has philosophy as its armature.     

A follow up study of a behavioral program for young people with learning disabilities and challenging behavior

This paper describes a pilot follow-up study of a behavioral program for 20 young people with learning disabilities and challenging behavior. Eighteen participants made good overall improvement during the treatment period, and this was partially maintained at follow-up. Eight had continued to improve, eight had deteriorated slightly and four had deteriorated markedly. Adaptive skills were generally maintained. The reemergence of challenging behaviors explained the difference between the Good and Poor Outcome groups. Those participants in the Good Outcome group were younger on admission, scored lower on adaptive skills and higher on challenging behaviors. In addition they had remained on the treatment programme for 12–18 months and had been discharged from the Unit for longer. The overall level of independent living had increased from preadmission and the majority of participants were living in less restrictive placements. These results confirm and extend the findings of previous research. The paper concludes by highlighting the need for more detailed longitudinal follow-up studies in this area.     

Teaching the Rescorla-Wagner model using STELLA-II

Although the Rescorla-Wagner model is widely taught in learning courses, most textbooks present a simplified version that does not contain all of its parameters. On the basis of Rescorla and Wagner 1972) and the Turbo PASCAL program by Lachnit, Schneider, Lipp, and Kimme! (1988), we created a simulation using STELLA-II, an icon-based program by High Performance Systems, Inc. We argue that this simulation facilitates teaching the complete Rescorla-Wagner model. Using trans-switching (Kimmel & Ray, 1978; Lachnit, 1986; Murrin & Kimmel, 1986) as an example, we demonstrate the effectiveness of the STELLA-II version of the Rescorla-Wagner model as a heuristic tool.     

Values and Valences: Variables Relating to the Attractiveness and Choice of Food in Different Contexts1

This study investigated relations between values and the attractiveness and choice of food in different contexts for a sample of 464 participants who completed a mail survey distributed in 12 supermarkets in metropolitan Adelaide, South Australia. Participants responded to 5 hypothetical scenarios describing situations, each of which presented 2 alternatives relating to the presentation or consumption of different foods. Participants also completed the Schwartz Value Survey (Schwartz, 1992). Results showed that measures of the attractiveness (or valence) of each alternative and choice of alternative were related to specified value types for some scenarios, depending on context and structural relations among the value types engaged by each alternative. Results also implied that choice of alternative was mediated by the valences.     

A Psychometric Evaluation of the Career Decision-Making Self-Efficacy Scale

A thorough psychometric evaluation of the Career Decision-Making Self-Efficacy Scale (CDMSES; Taylor & Betz, 1983) is provided. The construct of career decision-making self-efficacy, stemming from Bandura's (1977) self-efficacy theory, is discussed. A summary of the initial construction and development of the scale is provided, followed by a comprehensive review of the results of various investigations on the reliability and validity of the CDMSES. An overall evaluation of the CDMSES's psychometric strengths and weaknesses is given. The article concludes with ideas for additional psychometric research of the CDMSES and discusses the usefulness of the scale in career counseling and career development research.     

Finite-state recall revealed by backward learning curves constructed from confidence ratings

Two experiments were carried out to show that the constancy of Type II d’ in recall is not an artifact, but is due to finite-state processes as suggested by Bernbach (1967). The following conclusions were reached: (1) The constancy of Type II d’ is not an artifact due to the inclusion of intralist intrusions in the class of incorrect responses; (2) backward learning curves constructed from confidence ratings gave clear evidence of all-or-none recall; (3) recall appeared to be all or none whether the subjects learned by rote or with a mnemonic; (4) the discriminability index derived from Luce’s (1959) choice theory did not exhibit constancy over trials, unlike Type II d’ and despite the fact that backward rating curves indicated all-or-none processes.
