Abstract
Recent blink studies using a new paradigm named the “discrete trial paradigm” were reviewed. Traditionally the rate of eyeblinks or the number of eyeblinks made during a relatively long period of time has been used as a measure. Instead, the new paradigm emphasizes the temporal distribution of blink initiation contingent on the human information processing. Studies using the discrete trial paradigm have indicated that there exists a close relationship between eyeblinks and cognitive processes. The studies reviewed here suggest that (1) eyeblinks tend to be inhibited during some cognitive processes, i. e., task demand, attention and concentration, and (2) a burst of eyeblinks tend to be initiated upon the termination of the information processing. It is hoped that future research based on this new paradigm will provide an insight into the relationship between eyeblinks and the human information processing.
