Toddlers\u2019 lexical and grammatical competencies were assessed using the MacArthur\u2013Bates Communicative Development Inventory: Words and Sentences. The results, based on 3012 reports completed by parents, indicate an increase in the lexical size and on five measures of grammatical development (production of regular morphology, irregular morphology, over-regularizations, mean length of utterances and sentence complexity) across age groups. A main effect of gender was found for lexical size, production of regular and irregular morphology, production of over-regularizations and sentence complexity, with girls obtaining overall higher scores than boys. All lexical and grammatical development measures are positively correlated, even after controlling for age and gender effects. These findings are discussed in terms of their consistency with those obtained for other languages.<\/jats:p>","DOI":"10.1177\/0142723716689274","type":"journal-article","created":{"date-parts":[[2017,1,28]],"date-time":"2017-01-28T14:06:38Z","timestamp":1485612398000},"page":"267-284","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Parents\u2019 reports of lexical and grammatical aspects of toddlers\u2019 language in European Portuguese: Developmental trends, age and gender differences"],"prefix":"10.1177","volume":"37","author":[{"given":"Carla","family":"Silva","sequence":"first","affiliation":[]},{"given":"Irene","family":"Cadime","sequence":"additional","affiliation":[]},{"given":"Iolanda","family":"Ribeiro","sequence":"additional","affiliation":[]},{"given":"Sandra","family":"Santos","sequence":"additional","affiliation":[{"name":"Universidade do Minho, Portugal"}]},{"given":"Ana L\u00facia","family":"Santos","sequence":"additional","affiliation":[{"name":"Universidade de Lisboa, Portugal"}]},{"given":"Fernanda Leopoldina","family":"Viana","sequence":"additional","affiliation":[{"name":"Universidade do Minho, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2017,1,26]]},"reference":[{"key":"bibr1-0142723716689274","volume-title":"Elementos para a constru\u00e7\u00e3o de um teste de rastreio de perturba\u00e7\u00f5es do desenvolvimento sint\u00e1tico","author":"Afonso M.
