Dual Coding Theory—points in the same direction as our analysis. The same is true of Barsalou's work suggesting that we use internal information to understand at least some abstract words. To sustain this position, we put forward two lines of evidence: the first comes from psycholinguistic studies while the second examines deficits of semantic competence exhibited by people with Autism Spectrum Disorder. On the basis of our analysis, we put forward a classification that distinguishes between different kinds of concreteness and different degrees of abstraction: concepts/words referring to body experiences and basic emotions are described as analogous to concrete concepts/words because they are grounded in perceptual (i.e. propriosensitive) experience, while abstract concepts/words are considered more or less abstract depending on whether they are intratheoretical (and rely entirely on inferential information) or theoretical (and are partially grounded in perceptual—or more often in propriosensitive perceptual—information). In the last section of the chapter we consider two scales that have been used in psycholinguistic research to measure the degree of concreteness versus abstractness of words and we show that—used conjointly—they can provide a measure of the internal versus external grounding of specific words." /> The "proprioceptive" component of abstract concepts - Dellantonio Sara; Pastore Luigi | sdvig press
