The Psychological Refractory Period: Central Capacity versus Modularity as Related to the Processing of Language.
Collins, Vikki Kendrick; And Others
This study compared the central capacity and the modularity models for explaining language processing in kindergarten children. Using a microcomputer, 19 kindergarten children completed a visual letter-matching task that required a manual response. An auditory tone was emitted by the computer in a separate trial also requiring a press. For the dual task block, three stimulus onset asynchronies (SOAs) of 200, 400, and 1,000 milliseconds were randomly used to introduce the auditory tone. Each subject was individually instructed in response techniques and was individually tested. Ten of the subjects were tested for a second and third session. Response times were measured and recorded by the microcomputer. Results indicated that reaction time was significantly increased when one task was interrupted by another task. Reaction time to a tone was significantly affected by: (1) SOAs or the time interval used; (2) the letter match task of same or different letters; and (3) the session. Reaction time to a tone was not significantly affected by interactions between or among the factors. These results suggest that attention-demanding tasks may be postponed during serial processing. The explanation of refractoriness as demonstrated by a postponement or bottleneck in central capacity would seem tenable. (MM)
