Children who are exposed to languages with richer inflectional morphologies than English, such as Spanish, encounter instances of inflectional variation more often. Thus they may learn to recognize inflectionally varying words as instances of the same word at an earlier age than do learners of English. English- and Spanish-learning 3-year olds were taught novel verbs in a fast mapping task under two conditions: no-inflectional variation in which inflections did not vary between exposure and testing (e.g.,\n            <jats:italic>neps, neps<\/jats:italic>\n            ) and inflectional variation in which inflections alternated between exposure and testing (e.g.,\n            <jats:italic>neps, nepped<\/jats:italic>\n            ). Children\u2019s scores were significantly higher in the no-variation condition than in the variation condition. There were no significant differences between the performance of the language groups. These findings suggest that even children acquiring languages with relatively rich verbal inflection paradigms may not be able to consistently parse stems and inflections to associate inflectionally varying forms.\n          <\/jats:p>","DOI":"10.1044\/jslhr.4301.21","type":"journal-article","created":{"date-parts":[[2014,7,29]],"date-time":"2014-07-29T21:02:23Z","timestamp":1406667743000},"page":"21-33","source":"Crossref","is-referenced-by-count":29,"title":["The Effects of Inflectional Variation on Fast Mapping of Verbs in English and Spanish"],"prefix":"10.1044","volume":"43","author":[{"given":"Lisa M.","family":"Bedore","sequence":"first","affiliation":[{"name":"University of Texas at Austin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurence B.","family":"Leonard","sequence":"additional","affiliation":[{"name":"Purdue University West Lafayette, IN"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","first-page":"635","DOI":"10.2307\/1131837","article-title":"The role of discourse novelty in early word learning.","volume":"67","author":"Akhtar N.","year":"1996","journal-title":"Child Development"},{"key":"e_1_3_2_3_1","first-page":"157","volume-title":"Mechanisms of language learning","author":"Bates E.","year":"1987"},{"key":"e_1_3_2_4_1","doi-asserted-by":"crossref","first-page":"681","DOI":"10.2307\/1130953","article-title":"The development of verb concepts in children\u2019s use of verbs to label familiar and novel events.","volume":"61","author":"Behrend D.","year":"1990","journal-title":"Child Development"},{"key":"e_1_3_2_5_1","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1017\/S0305000900009648","article-title":"Morphological cues to verb meaning: Verb inflections and the initial mapping of verb meanings.","volume":"22","author":"Behrend D.","year":"1995","journal-title":"Journal of Child Language"},{"key":"e_1_3_2_6_1","doi-asserted-by":"crossref","first-page":"150","DOI":"10.1080\/00437956.1958.11659661","article-title":"The child\u2019s learning of English morphology.","volume":"14","author":"Berko J.","year":"1958","journal-title":"Word"},{"key":"e_1_3_2_7_1","volume-title":"Words and things.","author":"Brown R.","year":"1958"},{"key":"e_1_3_2_8_1","doi-asserted-by":"crossref","DOI":"10.4159\/harvard.9780674732469","volume-title":"A first language: The early stages.","author":"Brown R.","year":"1973"},{"key":"e_1_3_2_9_1","doi-asserted-by":"crossref","first-page":"348","DOI":"10.1016\/0749-596X(91)90041-H","article-title":"Phonological information for grammatical category assignments.","volume":"30","author":"Cassidy K.","year":"1991","journal-title":"Journal of Memory and Language"},{"key":"e_1_3_2_10_1","doi-asserted-by":"crossref","DOI":"10.1017\/CBO9780511554377","volume-title":"The lexicon in acquisition.","author":"Clark E.","year":"1993"},{"key":"e_1_3_2_11_1","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1007\/BF01067106","article-title":"A cross-sectional study of the acquisition of grammatical morphemes in child speech.","volume":"2","author":"de Villiers J.","year":"1973","journal-title":"Journal of Psycholinguistic Research"},{"key":"e_1_3_2_12_1","first-page":"27","volume-title":"The crosslinguistic study of language acquisition.
