Outline of Final Research Achievements

On responding to stimuli presented repeatedly, eye blinks are inhibited before and during stimulus, and eye blink frequency peaks after stimulus. The eye blink inhibition might be related to information expectancy and processing, and the peak of eye blink frequency might be related to the end of information processing. However, eye blink inhibition and occurrence in developmental disorder children (DDC) during Go/No-Go tasks is not clear. We compared correct answer, response time, intelligence scale, and eye blink timing between the DDC, the typical developmental children (TDC), and adults. Although the correct answer, reaction time and intelligence scale was not different between DDC and TDC, the DDC's eye blink frequency peak delayed in No-Go, and DDC’s eye blink was not inhibited before next stimulus. The DDC’s blink occurrence and inhibition at No-Go could be associated with a functional deficit in the prefrontal cortex, indicating new assessment for developmental disorders.
