![عکس صفحه اول مقاله: Effects of retention interval on performance in a numerical reproduction task Effects of retention interval on performance in a numerical reproduction task](/preview/png/2427624.png)
The retention interval (RI) between the sample and production phase in a numerical reproduction task was varied to determine whether a “produce-small” effect would be obtained with increased delays. Four pigeons were trained with a retention interval of 2 s, and then tested with intervals of 0.5 s and 8 s. Results showed a number-dependent, “produce-large” effect–response number increased when RI was increased-analyses of average response number and accuracy suggested RI affected responding most on the 2-flash trials with an 8-s RI. Additionally, discrimination between trial types decreased as RI increased. Existing explanations for the “choose-short/small” effect appear unable to account for these results; however the “produce-large” effect may be attributed to a disruption in stimulus control over responding.
