Perceptual Inspection Time: An Exploration of Tactics to Eliminate the Apparent-Movement Strategy
Abstract
The research reported herein is of broad relevance to the construction of culture-fair intelligence tests based upon processing-speed measurements. Three experiments used an inspection-time (IT) paradigm with a post-test questionnaire to segregate subjects into an apparent-movement strategy group and a no-strategy group. Experiment 1 replicated previous research by finding a significant IT/intelligence-test correlation only for subjects from the no-strategy group. Experiment 2 attempted to influence the probability of adopting the strategy by altering the standard IT task parameters. Only increased strategy use could be produced by our manipulations. Experiment 3 replicated Experiment 1 but added on alternative IT task designed to eliminate the strategy. The alternate IT task predicted IQ less well than for the no- strategy group in the standard task, suggesting the alternate was also susceptible to an unknown set of strategies. Finally, across all experiments, no reliable differences were found for the two groups of subjects with respect to IT or intelligence test performance. (sdw)
