Response location as a factor in primate pattern discrimination.

Abstract

"Thirteen monkeys were presented 832 two-choice color-discrimination problems in an automated version of the formboard situation. In this apparatus, stimulus patterns were projected upon two adjacent 3-in.-square screens and all Ss were required to respond to the centers of the screens. The results showed that under these conditions monkeys discriminate center cues more readily than those arranged upon the border. These data have been interpreted as reconfirming the importance of spatial S-R contiguity in primate discrimination learning." From Psyc Abstracts 36:05:5EJ43S.
