Two groups of subjects made magnitude estimations of a series of eight circles, each of which had its own color. All subjects received the same number of presentations in both sessions, with half the subjects receiving the same size-color pairing of the first session, and the remaining subjects receiving a different size-color pairing, in the second session, one week later. Interrepetition correlations of exponents for the middle four adjacent presentations were computed. All of the correlations were significantly different from zero with the exception of the intersession correlation of the control group. The control group exhibited a significant decrease in correlation across sessions while the experimental group remained stable. These findings were totally unexpected. A test of difference between intersession correlations was not significant. The results can not easily be explained within the framework of either the response bias or memory hypotheses.

This study sought to compare Viktor Lowenfeld's Haptic Visual theory of perceptual types with Herman Witkin's Field Dependent, FieldIndependent classifications, since previous research indicated apparent similarities. The major objective was to compare the two theories by administering five perceptual tasks to 34 college students who had been classified into perceptual types according to Lowenfeld's and Witkin's criteria. Thirty-four randomly selected, female, elementary education majors from Wright State University were administered a series of five perceptual tasks involving visual, auditory, tactile, and kinesthetic stimuli while an electroencephalograph (EEG) recorded their alpha wave responses eminating from the occipital lobe of the brain. Since alpha waves have consistently been found to be negatively associated with visual imagery, it was hypothesized that Lowenfeld's Haptic types, who theoretically function better through tactile and kinesthetic perception than through visual images, would produce a greater number of alpha waves during the specified time limit of each perceptual task, than the Visual type, who apparently relies upon his sense of vision as the dominant intermediary to his environment. It was further hypothesized that Witkin's Field Dependent types would correspond to the Haptic types, and the Field-Independent types would correspond to the Visual types as measured by the EEG.
