Abstract
Semantic Differential technique was applied to synesthetic tendencies or common affective effects between various stimulus categories of different sensory modalities; classical music, sounds, colours, forms, symbolic words, and movies. Factor analyses indicated three stable factors; evaluation, activity, and lightness(negative potency)across these six different stimulus categories. Classification of patterns of factor scores of 58 stimuli in different categories and cluster analysis based on these factor scores had been shown useful to classify these stimuli into affective groups independently of stimulus categories. Key words: Synesthesia, Semantic Differential, Affective meaning
