We examined the process of learning to see 2-dimensional forms, 3-dimensional solids and short distance in eight congenitally or early blind patients who acquired varying degree of sight after surgery. When we first asked them to recognize geometric solids such as cube, cylinder, cone and tetrahedron by using vison, it was found that this task was too difficult for them, even though they had the visual ability to identify 2-dimensional forms. The learning processes involved in attaining successful discrimination and identification are described here. The front distance of them became estimated mostly by the size of object at last. This study reveals the difficulty in transitioning from 2-dimensional discrimination to a 3-dismensional knowledge base.

The present experiment was planned to examine whether or not the congenitally blind after surgery were capable of seeing the subjective contour, when Kanizsa's original and a modified version of it were presented for the first time. Three subjects (M. O., To. M. and K. T.) who have continued a series of experiments for visual learning with us participated in the experimental runs. All subjects have already attained the ability to identify the 2D shape and solids. Initially it was expected that the subject's response could be classified as indicating that the subjective contours were seen or that they were not. However, it was found that (1) at least another two classes of responses should be added, and (2) that the commonly reported phenomenon of subjective contours in the normally sighted was rare in the congenitally blind subjects after surgery. A theoretical implication of the results is briefly discussed.

The characteristics of the visual and tactual activities were investigated in a congenitally blind person before and soon after an operation performed for regaining his sight. The subject was born blind due to congenital cataracts, and underwent aspiration of both cataractous lenses at the age of 9. Before the operation, his ERG was normal. After the operation he wore +12D lenses. The results obtained were as follows: (1) Before the operation, he could identify colors. To some extent, he could also count objects, discriminate the size of 2 two-dimensional rectangles or two circles. On the other hand, he could not identify two-dimensional figures. (2) During the 15 days after the second eye operation, his percentage of correct responses increased in all tasks, except for discrimination of the size of 2 two-dimensional circles. (3) Postoperatively, the patient no loger attempted to touch objects after counting them and discriminating the size of 2 two-dimensional rectangles, but with either size discrimination of the circular shapes or identification of shapes, he touched them after looking at them, just as before the operation.

Near-infrared red spectroscopy (NIRS) is a noninvasive method that uses changes in cerebral blood volume (CBV) to measure relative changes in tissue concentration of oxygenated, deoxygenated and total hemoglobin. We used this technique to determine the cortical activation area during Japanese grammatical processing. To assess the relative changes in total hemoglobin, local changes in near-infrared absorption were measured simultaneously from seven points in both hemispheres. Nine subjects were presented target stimuli, and were asked to decide whether the attendant particle was “ga” or “wo” in Japanese grammatical tasks (experimental conditions), and whether the relative position was “front” or “back” in positioning tasks (baseline and control conditions). To control subvocal rehearsal and conceptual driven processing, the same Kanji character was presented visually as a target in the experimental and control conditions. Total hemoglobin increased in Broca's area when subjects made judgments in Japanese grammatical tasks, compared to positioning tasks. These results suggested that the task of deciding particles in Japanese grammatical processing might be an effective and objective method to assess language disorders.

In order to clarify the characteristics of perception of visual space in the early or congenitally blind who have just gained sight after surgery, a series of experiments covering a period of over 10 years were conducted. Subject KT in this paper, who lost her sight binocularly due to congenital cataract, received the operation on her left eye at the age of 15. The following results were obtained: (1) The perceived size of an object placed at various distances on a table decreases when the physical distance exceeds 20cm approximately. The ratio of perceived sizes to physical distances demonstrates that the size constancy is not so high as that of the normally sighted adult. (2) Color perception was slightly easier than that of shape, but it became difficult when the observation distance (D) extended 60cm and when the size of color paper was small. (3) Identification of the shape of a figure was difficult when the figure was presented at D>35cm. At a near distance she could scan the shape as a whole, but at a far distance, KT had to employ the strategy of partial scanning.

Perception is treated as a joint function of the value orientation of the subject and the value of stimulus words. Three perceptual mechanisms: perceptual selection, perceptual fixation, and perceptual resonance are measured by recognition, memory, and association, respectively. The results of the study are as follows: The three perceptual mechanisms are facilitated when the subject has high-or low-value orientation to the stimulus words and when the stimulus words have value and meaning. That is, high-or low-valued stimulus words are fast perceived, long memorized and are likely to be associated with some other words.
