Group Data

Rhesus monkeys were trained to criterion on a 2-stimulus and a 5-stimulus pattern discrimination task. The probabilities of response to the various stimuli throughout learning are examined for individual Ss, and it is found that Ss exhibit consistency in the order and manner in which incorrect stimuli are eliminated. This suggests a simple mathematical description of the process, which is used to deepen the analysis of the data, permitting estimation of individual learning parameters and construction of more meaningful summaries of the group data.

The Relationship ◽  
Dark Room

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.
