This paper investigates whether affixal homonymy, the phenomenon that one affix form serves two or more semantic/syntactic functions, affects lexical processing of inflected words in a similar way for a morphologically rich language such as Finnish as for morphologically restricted languages such as Dutch and English. For the latter two languages, there is evidence that affixal homonymy triggers full-form storage for inflected words (Bertram, R., Schreuder, R., and Baayen, R. H. (in press). The balance of storage and computation in morphological processing: the role of word formation type, affixal homonymy, and productivity. Journal of Experimental Psychology: Learning, Memory, and Cognition; Sereno and Jongman (1997). Processing of English inflectional morphology. Memory and Cognition, 25, 425-437). Two visual lexical decision experiments show the same pattern for Finnish. Apparently, the substantially richer morphology in Finnish does not prevent full-form storage for inflected words when the affix is homonymic.
This report investigates whether preverbal infants distinguish between humans and mammals within the animate domain. In Experiment 1, 3 groups, aged 7, 9, and 11 months (N = 58), participated in an object-examination task. Infants were presented with 10 different three-dimensional toy models from one category (humans or mammals), followed by an exemplar from the other category. All groups habituated to the familiarization stimuli and dishabituated to the out-of-category item. In Experiment 2, 2 groups of infants, aged 5 and 7 months (N = 40), participated in a familiarization-novelty preference task. Four pairs of color photos of objects from the same category were presented twice, and then infants received a test pair that included one new object from the already-familiar category and one out-of-category item. Infants habituated only to humans, and 7-month-olds, but not 5-month-olds, dishabituated to the out-of-category exemplar. Implications for the development of categorical thinking during the first year of life are discussed.
