JOURNAL FREE ACCESSUtility functions concerning supposed moneys were obtained at the level of interval scale by means of the method of successive categories. They were found to conform to the Fechnerian logarithmic equation, while ratio utility scale constructed by double stimulus method had been found to be congruent with the Stevens' power law. Individual differences in the categorical ratings were discussed by factor analytic technique. A new and simple calculation method based on simplex correlation matrix was proposed on assumption of random walking model about judgment variability.View full abstractDownload PDF (705K) -

JOURNAL FREE ACCESSThe conditioned emotional response (CER) and basal emotional level (BEL) were studied as a function of predictability and escapability of an electric shock in a conditioned suppression situation using 32 rats. One group of rats could escape shock by responding into an escape-space upon receiving shock which was signaled. The other two groups were yoked with the above group with respect to shock experience. But for one of them, shock was unsignaled. There was no significant difference between the two signaled groups with respect to CER. As to BEL, the signaled escapable group was the lowest, the signaled-inescapable group was next, and the unsignaled-inescapable group was the highest and the differences were all significant.View full abstractDownload PDF (595K) -
FIXED-INTERVAL EFFECTSDAVID SHAPIRO, TAKAMI WATANABE1971 Volume 13 Issue 3 Pages 123-130

JOURNAL FREE ACCESSPalmar skin potential responses in human subjects were reinforced under several fixed-interval schedules of reinforcement varying from 50 to 150 seconds. With the exception of an initial response burst immediately after reinforcement, the response characteristics appear to be comparable to those observed for skeletal operants. Data are also presented showing that efficiency of performance is improved when subjects are provided an external clock. Concomitant changes in other physiological variables recorded do not show any consistent evidence for somatic mediation of the learned patterns of skin potential activity.View full abstractDownload PDF (621K) -
TSUNETAKA OKITA1971 Volume 13 Issue 3 Pages 131-138

JOURNAL FREE ACCESSTwo experiments were conducted to determine whether autonomic responses in man could be modified by avoidance procedure. In Experiment I, experimental Ss could avoid the shock on the acquisition trials when they produced galvanic skin response. During acquisition and extinction, experimental Ss were greater in response frequency than yoked control Ss. In Experiment II, the UCS was omitted for Ss whose heart rate increased, and for the other group, for those whose heart rate decreased. Heart rate of the decrease group tended to decrease more rapidly than that of the increase group, but the number of shock presentations was different between groups. These results in Experiment I and II were somewhat ambiguous and not a convincing demonstration of the autonomic avoidance conditioning, although in Experiment I there was a significant difference between groups.View full abstractDownload PDF (598K) -
VISUAL RECOGNITION OF QUANTIZED KATA-KANA LETTERS UNDER FORWARD AND BACKWARD MASKING BY RANDOM NOISETAKAO MATSUDA1971 Volume 13 Issue 3 Pages 139-147

Released on J-STAGE: February 24, 2009
JOURNAL FREE ACCESSThe relationship between the recognizability of quantized letters and the forward and backward masking by noise, and some structural characteristics of letters determining their recognizability or confusability were assessed by obtaining 4500 recognition responses from each of 3 Ss under 5 different noise levels (.06-.75) for the masking stimuli at 9 different stimulus-onset-asynchronies (-250-+200 msec). U-shaped functions of correct identification of letters were obtained both for noise level and for stimulus-onset-asynchrony. However, these functions were not symmetrical: the lower noise levels produced stronger decrements in letter recognizability than the higher noise level and the forward masking was stronger than the backward masking. One of the determinants of letter recognizability was considered to be the number of cells consisting the quantized letters as well as the distinctiveness or similarity in structural components of letters.View full abstractDownload PDF (669K) -

JOURNAL FREE ACCESSResponse latency to get the impression of depth in stereoscopic observation was measured, using pairs of computer generated random number patterns as stereo pairs. Each of eight stereo pairs with different geometrical disparities was presented 30 times in a haploscopic device. The device was carefully adjusted to obtain the condition in which no change of convergence and accomodation was required to get a binocularly fused image in any trials. The amount of the depth impression was rated by each S with 11 numbers from 0 to 10. The results showed that (a) the response latency between the onset of presentation of a stereo pair and the S's report of the impression of depth is a increasing function of disparity to some level: (b) the latency decreases, as a function of the number of trials, to reach an asymptote: (c) the amount of depth impression obtained with the rating method increases almost linearly as a function of disparity throughout the range of disparity used in this study.View full abstractDownload PDF (329K)
