We developed a new set of modality exclusivity norms for 643 Italian concrete and abstract words. In addition to sensory scores for each perceptual modality, we calculated Maximum Perceptual Strength, Modality Exclusivity, Summed Perceptual Strengths, Dominant Modality and Entropy. We augmented the database with corpus-based (Zipf Frequency, Contextual Diversity, Orthographic Neighbourhood Size, OLD20, Length in Letters) and rating-based covariates (Familiarity, Age of Acquisition, Context Availability) that are known to influence word processing. We performed split-half correlations to confirm the reliability of our norms and explored their correlational structure.
