[Analysis of resolution of CNV (author's transl)].
The present study was designed to explore the factor affecting the resolution of CNV by using the paradigm in which the attention was experimentally manipulated. The control group (N=13) was given an instruction for conducting the ordinary CNV task, while the experimental group (N=26) was instructed to direct the attention to the different S2 durations. The results obtained showed that in the control group the CNV resolution occurred after the S2 onset, although in the experimental group the resolution occurred after the S2 offset. Considering the findings of this study and of Kakigi, Matsuda, and Hagino (1978) together, it was suggested that the CNV resolution was initiated by the psychological factor, not depending upon the external stimulus nor the key pressing response.
