Psychological Refractory Period Effect

10 undergraduate students were tested in a psychological refractory period paradigm. Stimulus 1 was a visual discrimination task (same-different) and S2 was a 1,000-Hz tone. Discriminability of S1 and ISI were varied. Ss always had to respond to S2, but to S1 only when it was “same.” Discriminability of S1 was found to affect R2, irrespective of whether or not S1 was followed by an overt response. Such a result poses difficulties to expectancy and response-conflict theory.

An attempt to distinguish serial from parallel models of central processing was made by manipulating the relative complexity of R2 and observing the effect of this manipulation on RT1 in the Psychological Refractory Period paradigm. 14 subjects performed under two conditions, either a simple or complex R2. Experimental controls were used to prevent a possible grouping effect of responses. The results did not support a parallel model of central processing but did support a serial view. Implications of results, combined with previous findings, for a more flexible model of central processing were discussed.
