The effect of repetitive presentation and inducement of simplified form of Kanji on visual field differences

Japanese students (N = 32) participated in a tachistoscopic recognition task. They were unaware of a simplified form of kanji designed in the People's Republic of China. A kanji written in the simplified form was presented to the left or right visual field (LVF or RVF). Ss were required to depress an index-finger-operated microswitch with the appearance of two of the four stimuli, & a middle-finger-operated microswitch when the other two were presented. Two tests, each including 4 blocks of 24 trials, were conducted with a one-week interval. Each kanji was randomly presented six times in a block in either field. As a result of test 1, visual field difference was not generally found. However, it reversed between the first & second half. LVF advantage was found in the first, RVF in the second. At the end of test 1, Ss were divided into four groups, & three of them were given inducement with some attribute of the stimuli. The other group was not given any inducement. As a result of test 2, conducted one week later, visual field difference was not found in the pronunciation-induced groups. On the other hand, RVF advantage was found in the meaning-induced group & noninduced group. 3 Tables, 1 Figure, 22 References. HA
