Successive and Delayed Discriminations in a Tactile Relational Array: An Exploratory Study

Abstract

40 Ss were tested to study the discriminations made in length in a relational array using the tactile sensory mode. No differences were noted in error due to successive comparison and delay treatments, sex of S, or order of stimulus presentation. Analyses of errors on the tactile discrimination tasks indicate that Ss were discriminating at between 1 and 2 mm. of length.
