Yoh Sugisaki, a Pioneering Educational Psychologist in Japan
Yoh Sugisaki (1877–1943) was a psychologist who worked at Nagano Normal School from 1916 to 1939. He introduced a series of laboratory exercises into his psychology lectures and encouraged students to cooperate with each other in data analysis and report writing. He inspired students who were losing sight of their goal and motivated them to concentrate on further learning. In Nagano, he organized self‐training groups for uncertified teachers in l…
Visual perception and perceptual processing in real and virtual environments
It was still hot all day and night at the end of September 2001 in the ancient town of Nara. The Second Joint Japanese-Swiss Scientific Seminar titled “Visual Perception and Perceptual Processing in Real and Virtual Environments,” supported by both the Japanese Society for the Promotion of Science (JSPS) and the Swiss National Science Foundation (SNSF), was held at Nara from 25–28 September 2001. It was no accident that researchers of visual perc…
Effects of light stimulus upon simple reaction time and EP latency to the click presented with different SOA
Click and light were presented in pairs with varying stimulus onset asynchronies (SOAs) and the subjects were asked to respond to the click onset. SRTs and EPs were obtained for two levels of click intensity and were plotted as a function of SOAs. As the related EP component, Nc, or the negative peak immediately following the click onset, was taken and the Nc recorded from Cz was analyzed. Although the larger Nc amplitudes occurred with shorter S…
Strain differences of mice in response to the shock-situation
Two experiments were conducted to investigate the long-term effects of stress upon responses in inbred mice, C57BL/6J and CS. In Experiment I, the mice received intermittent electric shocks for five hours in a day for 15 days. Activity rhythms and the body weight were measured in the home cage, and locomotion and the body weight loss in the shock box. In the C57BL/6J mice, the body weight decreased over days, while the body weight loss in the sho…
A relationship between the Broca-Sulzer effect and visually evoked potentials
The relationship between the Broca-Sulzer effect and visually evoked potentials (VEPs) was examined with two subjects. In the psychophysical experiment, a flash of disc subtending 52′ in visual angle and of one of the 11 durations ranging from 0 (no stimulus) to 1000 ms was presented by means of a Maxwellian view system. The luminance levels were at 312, 987, and 3120 cd/m2. Brightness judgments were made with the method of magnitude estimation. …
Discriminatory Ability of Pattern in the Cat
The ability of kittens in discriminating length-breadth ratio of geometrical figures was examined with a tracking method. In Experiment I, kittens were trained to discriminate a rectangle from a square, both in free orientation and fixed orientation tasks. In the former task, the spatial orientations of the stimulus figures presented were varied randomly from trial to trial, and in the latter, the orientation of the figures was fixed. The results…
Strain Differences in the Mouse's Wheel-Running Behavior
The present study examined the strain differences in the type of diurnal rhythm of wheel-running among 12 strains of mice. Test was done in the home-cage situation by placing the wheel over the nest box for a week. Strains used in the experiment were A, CBA, C3H, C57BL/6J, DBA, CS, DDK, KR, KSB, NC, BS and Mom. A, DDK, DBA and KR were classified as Type-A, the mice of which were active only at night. BS, CBA, C3H, C57BL/6J, KSB and NC were of Typ…
Chick's Avoidance of Visual Pitfalls Under Monocularized Condition
20 monocularized chicks were tested on visual pitfalls. They avoided visual pitfalls as successfully as binocular ones except that the former exhibited more remarkable peeping into visual pitfalls accompanied by large head movements than the latter. These findings appeared to suggest that the detection of motion parallax was made easier by means of taking an unclosed eye excessively for the compensation of monocularization. Additionally, some fin…
Development of Bilateral Transfer of Skills in the Mirror-Tracing
Bilateral transfer effect in the mirror-tracing task was examined for 7 age groups. Each group contained 20 Ss of mean age 8, 10, 12, 14, 17, 21, 32, respectively. A group of Ss was tested twice with the nonpreferred hand and was divided into matched groups, according to the averaged time score. Ss were tested again with the nonpreferred hand for 6 trials, after 16 trials with the preferred hand in the experimental group and after a 15-minute res…
A Further Study on Chick's Avoidance of Visual Pitfalls
The new type of visual pitfall apparatus was devised to separate motion parallax from density difference and the chick's avoidance of the pitfall was observed. Visual pitfalls were laid out to block the chick's straight-forward locomotion. Its locomotion was traced until it escaped from the two-fold pitfall arrangement. 140 naive male chicks were assigned to each of 7 conditions. In the conditions with motion parallax and density difference, chic…
Chick's Avoidance of Visual Pitfalls
Chick's avoidance of visual pitfalls was observed in a freely explorable open field situation. Fifty-one naive male chicks from 26 to 36 hours of age were used. After habituation a group of three animals was assigned to each of seventeen conditions and observed for five minutes. Conditions were classified into three; homogeneous non-pitfall, heterogeneous non-pitfall and pitfall situations. Animals successfully avoided pitfalls when motion parall…
The Field-Force as Measured by the Apparent Movement of a Small Light Point (1)
The purpose of the present study is to measure the field-force of visually perceived figures through a new phenomenon that has never been used.With the brief presentation of a small light point (test-point) around a figure, the test-point appears to move swiftly away from the figure and back to it.To measure the amount of this apparent movement, the scale-point was presented on the opposite side to the figure, and its luminous intensity to counte…
