Titrating delayed matching to sample in children
Abstract
Studied 40 51-130 mo. Olds in 5 groups based on ca in 60 experimental trials on a titrating delayed red-green matching-to-sample task. The length of the delay for an individual s was varied as a function of s's errors. 2 consecutive correct matches increased the delay by 2 sec.; an incorrect match decreased the delay by 2 sec. The average delay achieved was directly related to ca in that the 51-60 mo. Old ss were unable to perform accurately beyond a 0-sec delay while the 121-130 mo. Old ss performed correctly at delays greater than 40 sec. (16 ref.)
