| Abstract: | Three absolute identification experiments examined the effects on sequential dependencies of 2 factors: stimulus information and the number of stimuli used. Data were analyzed by multivariate information analysis. In Exp 1 with 5 university studentswith experience in absolute identification experiments, the stimulus modality was pure tone frequency under masking and no-masking conditions and 4, 6 10, and 16 tones were used. In Exp 2 with 5 university students, luminance levels of light circles were used as stimuli and number of luminance levels was 10 or 16. In Exp 3 with 6 university students, the stimuli were pointer positions along a horizontal line and they were presented either within a small or a large range to manipulate the stimulus information available. Results show that the sequential dependencies became larger as the stimulus information was decreased and as the number of stimuli was increased. Results are discussed in the context of models of sequential dependencies. Results of a multiple regression analysis on the data were compared with those of the information analysis.
