In four word-translation experiments, we examined the different representational frameworks theory (Crutch & Warrington, 2005) that concrete words are represented primarily by category whereas abstract words are represented by association. In our experiments, Chinese-English bilingual speakers were presented with an auditory Chinese word and three or four written English words simultaneously and asked to select the English word that corresponded to the auditory word. For both abstract and concrete words, higher error rates and longer response times were observed when the English words were categorically or associatively related compared to the unrelated conditions and the magnitude of the categorical effect was bigger than the associative effect. These results challenge the different representational frameworks theory and suggest that although category and association are important for representing abstract and concrete concepts, category plays a greater role for both types of words.Keywords: Concrete and abstract words; Semantic processing; Semantic categorical and associative effects; Bilingual translation 3 Investigating the representations of concrete (e.g., mouse) and abstract words (e.g., future) has important implications for understanding how our memory of factual information and general knowledge of the world (i.e., semantic memory) is represented. A number of studies show that concrete words are more easily recognized and memorized in various cognitive tasks (e.g., lexical decision, word reading) compared to abstract words (e.g., James, 1975;Kroll & Merves, 1986; Paivio, 1971;Strain, Patterson, & Seidenberg, 1995; see Paivio, 1991, for a review). More importantly, individuals with semantic memory deficits show a selective impairment of concrete knowledge with relatively preserved abstract knowledge or vice versa (e.g., Breedin et al., 1994; Sirigu et al., 1992;Warrington, 1975;Warrington & Shallice, 1984), suggesting that concrete and abstract concepts are represented in a different way.Concepts may be represented by taxonomic categories defined by the overlap in the semantic features between concepts (e.g., ducks and pigeons are in the bird category, as they have wings, feathers and can fly), or alternatively, by the links between concepts that tend to co-occur in language or which form familiar scenes or events (by association, e.g., "The mouse ate the cheese"). Most research has focused on concrete concepts, showing that semantic category and association both play a key role in representing concrete concepts (e.g., Kalénine et al., 2009;Sachs, Weis, Krings, Huber, & Kircher, 2008;Sachs, et al., 2011;Schwartz, et al., 2011; for reviews, see Hutchison, 2003;Mahon & Caramazza, 2009;Martin, 2007), but the representations of abstract concepts are less explored. The recent different representational frameworks theory proposes that category and association are important for representing both concrete and abstract words but concrete words rely more on category whereas abstract words rely more on ...
