Experiment 43

2-way split-plot Analysis of Variance

It is proposed that face recognition is less affected by repeated exposure to the stimulus than is recognition of other visually presented objects. In order to test this suggestion, two sets of stimuli are chosen, one set consisting of 50 cartoon faces and the other set consisting of 50 line drawings of everyday objects. A random half of each set is used in the first phase of the experiment. A group of ten participants views each of these stimuli once (Group 1); another group of ten participants views them twice (Group 2). The second phase of the experiment is a recognition test. All 100 items are presented and each participant is required to identify any stimulus that was presented in the first phase.
