- Abstract
Does the format in which we experience our moment-to-moment thoughts vary from person to person? Many people claim that their thinking takes place in an inner voice and that using language outside of interpersonal communication is a regular experience for them. Other people disagree. We present a novel measure, the Internal Representation Questionnaire (IRQ) designed to assess people's subjective mode of internal representations, and to quantify individual differences in "modes of thinking" along multiple factors in a single questionnaire. Exploratory factor analysis identified four factors: Internal Verbalization, Visual Imagery, Orthographic Imagery, and Representational Manipulation. All four factors were positively correlated with one another, but accounted for unique predictions. We describe the properties of the IRQ and report a test of its ability to predict patterns of interference in a speeded word-picture verification task. Taken together, the results suggest that self-reported differences in how people internally represent their thoughts relates to differences in processing familiar images and written words.
