The dimensions of tonal experience: A nonmetric multidimensional scaling approach

Subjects were required in each trial to directly compare two pairs of tones and indicate which pair of tones had the greater subjective difference or dissimilarity. Eleven tones differing in both intensity and frequency were employed. Subjects made binary comparisons among the 55 tone pairs which can be formed from the set of 11 tones. These paired comparisons of tonal intervals were used to determine a two-dimensional Euclidean representation for tonal experience. Loudness and pitch appeared as orthogonal dimensions in this representation. However, a 45-deg rotation of loudness and pitch axes produced axes which could be identified as volume and density. This relationship suggested that volume and density were simple functions of pitch and loudness. Volume and density predictions based on this two-dimensional representation were shown to provide a good account of the data from three experiments on volume and density.     

Outcome in short-term group psychotherapy

This study examines the effectiveness of planned dynamic short-term group psychotherapy in a health maintenance organization setting. The groups, conducted by experienced short-term psychodynamically trained therapists, focused on common life-stage issues. A pretest/posttest design was employed; group participants completed a battery of self-report measures before, after, and 4–6 months after treatment. Group participants made statistically (and clinically) significant positive changes on the majority of change measures. They saw themselves as improved on target problems, became far less symptomatic, and reported considerable growth in interpersonal functioning.     

Methodological pitfalls in predicting counseling success

Prediction models employing multiple linear regression of raw scores, multiple linear regression of factor scores, the single best predictor, and a nine-point decision rule index were compared. The subjects were 296 clients undergoing vocational counseling and evaluation. Predictor variables included performance ratings, demographic variables, and WAIS subtest scores; the criterion was employment status upon program completion. The least statistically sophisticated model, employing the single best predictor, was the most successful approach. Considerable shrinkage in power of prediction was demonstrated upon cross-validation particularly for multiple linear regression of raw scores model, indicating the necessity of cross-validating prediction schemes. Additional suggestions are made to those designing prediction studies.     

Improved techniques for the measurement of consummatory behavior in fishes

Improvements on a technique for the study of consummatory behavior and appetitive conditioning in fishes are described: a target-strike detector module easily incorporated into conventional relay programming equipment, a liquid-food formula highly attractive to goldfish and carp, a reliable Teflon-headed syringe plunger capable of handling gritty foods, and a silent food-pumping system.     

Punishment in the goldfish as a function of electrode orientation

For each response to a nipple from which they were trained to take liquid food, goldfish were punished with a brief ac shock administered through a pair of stainless steel electrodes placed either to the right and left of the animal, over and under it, or in front and back of it. As anticipated, on the assumption that the aversiveness of shock is a function of the potential difference across the animal's body, the right-left orientation of the electrodes was found to produce the least suppression of feeding and the front-back orientation the most.     

Measurement of supernatural belief: sex differences and locus of control

Although we live in an age dominated by science and technology, there exists an increasingly popular anti-science sentiment. This study describes the development of a scale to assess the degree of personal acceptance of supernatural causality versus acceptance of scientific explanation. In addition to the psychometric data concerning validity and reliability of the scale, data are presented which showed the personality factor of supernaturalism to be independent of orthodox religious attitudes. Results indicated a significantly greater supernatural acceptance for women, and a positive relation of supernaturalism with external locus of control.     

Clarifying the nature of the distinctiveness by domain interaction in conceptual structure: comment on Cree, McNorgan, and McRae (2006)

The conceptual structure account of semantic memory (CSA; L. K. Tyler & H. E. Moss, 2001) claims that feature correlation (the degree to which features co-occur) and feature distinctiveness (the number of concepts in which a feature occurs) interact with domains of knowledge (e.g., living vs. nonliving) such that the distinctive features of nonliving things are more highly correlated than the distinctive features of living things. Evidence for (B. Randall, H. E. Moss, J. M. Rodd, M. Greer, & L. K. Tyler, 2004) and against this claim (G. S. Cree, C. McNorgan, & K. McRae, 2006) has been reported. This comment outlines the CSA, discusses Cree et al.'s (2006) critiques of the Randall et al. (2004) experiments and the CSA, and reports new analyses of property norm and behavioral data, which replicate the results reported by Randall et al. (2004).
