JOURNAL FREE ACCESSFive groups of 15 Ss engaged in a monitoring task for 1hr. Their task was to detect signals that were presented on one of the 4 dials placed on a display panel. The signal was pointer deflection of greater amplitude and was presented aperiodically 24 times during the 1hr period. The locus on which the signals were presented was alternated from one dial to another at irregular intervals. The alternation occurred 3 times in three 3 switch groups, 9 times in 9 switch group and none in Control group. Detection percentage of signals was significantly higher (p<.05) in 9 switch group than in Control group. It was an evidence that supported the expectation of this study. Furthermore, any isolated occurrence of the alternation proved not to have any appreciable influence on signal detection. Implications of these findings were discussed in relation to Filter and Arousal theories of vigilance.View full abstractDownload PDF (652K) -

JOURNAL FREE ACCESSIn a follow-up of an earlier study comparing the extreme response tendencies of college students, a similar study was done of 12-year old children of these two cultural groups. The Japanese children of both sexes were found to make significantly fewer extreme (E) responses and significantly more intermediate (I) responses than the American children, as hypothesized. Comparisons between Japanese children and Japanese college students revealed no significant differences. However, similar comparisons between American children and American college students found the children making significantly more E responses and significantly fewer I responses. These findings were thought to support inferences about differential child-rearing practices in the two cultural groups and their effects on the development of restraint.View full abstractDownload PDF (266K) -

JOURNAL FREE ACCESSA stochastic model is developed in order to describe random fluctuations of the latency that the scanner consumes when he recognizes tactually the upper-case letters of the alphabet with his right finger tip. A mode of operation of the hypothetical decision-making mechanism is assumed to be a serial processing mode from which a probability density function of processing-time is derived, and the estimation procedure of the parameters is discussed. It is shown that the present model accounts satisfactorily for the main portion of the data obtained from 2 tactile scanners. An interpretation is put upon the estimated values of the parameters.View full abstractDownload PDF (477K) -

JOURNAL FREE ACCESSThis study was designed to determine how well Japanese students can evaluate the intelligibility of their own English hearing reception, applying the detectability measure of the signal detection model. 4 types of English hearing tests were given to the Ss: Aural perception (Test 1), words (Test 2), word in sentences (Test 3) and meaning (Test 4). The mean detectability score for Test 1 was lowest (d′=0.742) and for Test 3 was highest (d′=1.403). In Test 3 and 4, the relation between the detectability score and the achievement score was significant at 1% level, but it was not significant in Test 1 and 2. The data were analysed in terms of ROC curve. The result suggested some complex relationship between the achievement score and the detectability score, and the discussion was made on the possible factors affecting the detectability score.View full abstractDownload PDF (559K) -

JOURNAL FREE ACCESSTo assess the effect of stimulus similarity between original and shift tasks on intradimensional (IN) and extradimensional (EX) shifts under 2 levels of training, 4 to 6 years old children were trained on a 2-dimensional discrimination task. The stimulus change was determined by whether the stimulus values in relevant and irrelevant dimensions of an original task were the same as those of a shift task or not: Pattern 1 (same stimuli in relevant and irrelevant dimensions, same-same), Pattern 2 (same in relevant but different in irrelevant, same-different), Pattern 3 (different-same), and Pattern 4 (different-different). The results were that (a) the IN shift was easier than the EX shift under all patterns, (b) the EX shift was faster under Patterns 2 and 4 than under Patterns 1 and 3, and (c) the IN shift was faster under Pattern 4 than under Pattern 2. The results were discussed with reference to 2-stage theories which assume the transfer effect of mediating or attentional responses and original instrumental responses.View full abstractDownload PDF (539K) -

JOURNAL FREE ACCESSIn order to explore the structure and geometry of binocular visual space, the extent to which the visual space is approximated by Euclidean geometry was examined through the application of multidimensional scaling method. Five experiments were carried out, with stars in night sky and with small light points in the dark room. The S was allowed to move his head to fixate each stimulus and made ratio judgments about apparent interpoint distances. In each case, the configuration of light points in perception was reproduced fairly well by the configuration constructed in Euclidean space by the above mentioned procedure. However, the shape of configuration in perception was not the same with the shape of stimulus configuration, which seems to suggest that the correspondence between the configurations is more complicated than was assumed by Luneburg though the situation is not directly comparable with that in his model.View full abstractDownload PDF (669K)
