Pattern Area and Discrimination Learning with Pattern Spacing, Pattern Height, Pattern-Border Contiguity, and Pattern Manipulation Controlled

Abstract

The relationship between pattern area and pattern discrimination learning was explored. The possibly confounding effects of pattern spacing, height, contiguity, and manipulation were removed or controlled by: (a) presenting illuminated .25-, 1-, and 4-sq. in. patterns in a totally dark room, (b) alternating correct and incorrect patterns in a randomly determined temporal succession, (c) equating pattern height for all pattern-area conditions, (d) prohibiting pattern manipulation. Increasing pattern height from 1 to 4 sq. in. still resulted in improved learning. Results were interpreted in terms of utilization of brightness and/or size differences as cues to pattern discrimination.
