The discrimination of dot patterns as a function of number and average separation of dots.

Abstract

A study of the variables involved in the discrimination of dot patterns. A series of 120 different patterns were presented for each number of dots from two to seven. Results show that Ss could detect a difference in the relative positions of three dots on a pair of patterns better than on either two dots or any other number up to seven. The more widely separated the dots, the less accurate the discrimination. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
