On the nature of subjective scales

A number of problems connected with psychophysical scaling are pointed out and solutions suggested. The importance of searching for invariant relations ("laws") is stressed and the advantage of dealing with intrasubjective relations—thereby avoiding the "physicalistic trap"—is emphasized. Two series of experiments, concerning time perception and similarity, are discussed and it is concluded that they support the validity of subjective scales. Finally the role of the observer in scaling experiments is commented on.     

Time perception: Effects of sex and sound intensity on scales of subjective duration

Six women and six men reproduced ten time intervals varying in logarithmic steps between 1.3 and 20 s. The durations were indicated by white noise of 10, 25, 40 and 55 dB SL, different sound intensities in different sessions. It was found that (i) greater sound intensity entails shorter reproductions, and (ii) reproductions by male observers are shorter than those by female, although for both (i) and (ii) there is an interaction with the standard durations. The data were treated in accordance with the "parallel-clock model" (Eisler, 1975), whereby the parameters of the psychophysical power function are determined from duration reproduction data. As in previous experiments (Eisler, 1975), the data showed a break in the function entailing two segments. The effect of sound intensity could be attributed to the exponent, which was lower for stronger noise, and the effect of sex to the weight coefficient of the upper relative to the lower segment of the psychophysical function, the coefficient being lower for men.     

The relationship between creativity,teacher ratings on behavior,age, and gender in pupils from seven to ten years

The aim of this study was to examine the relationship between the performance on a test for the assessment of creative behavior and teacher ratings on scales for the assessment of behavior commonly seen as negative. The sample consisted of 71 Austrian elementary school students (33 boys and 38 girls), from seven to ten years of age. The children were tested with the German “Creativity Test for Preschoolers and Pupils” by Krampen. This test is based on Guilford's model of the structure of the intellect and it assesses divergent thinking with respect to behavioral, figural, and semantic tasks. The teachers completed the “Conners Abbreviated Teacher Rating Scale,” a teacher rating questionnaire based on the DSM‐IV criteria to assess inattentive and impulsive/hyperactive behavior, and a researcher self‐constructed teacher rating questionnaire, containing the scales “dissocial behavior”, “introverted behavior”, and “creative behavior”. It was found that more impulsive/hyperactive and disruptive behavior was related to a better performance on fluency and more attentive and less introverted behavior were related to a better performance on flexibility. Additionally, it was found that boys present more alternatives in active behavior than girls. The results lead to the conclusion that more lively behavior of pupils should not be seen negatively, as such behavior seems to be a predictor of creative thinking.
