This experiment tested the hypothesis that the mere presence of an observer would facilitate performance on simple mazes and hinder performance on complex mazes. Sixty female students traversed either a multiple T-maze or a multiple +-maze either with or without an observer. The factors of maze-type and observer-presence did not interact in a manner consistent with previous researches. On both mazes, the “observed” subject made more errors and needed more trials to reach the criterion than the “alone” subject.
