In order to answer these questions, the Hungarian adaptation of the MacArthur-Bates Communicative Development Inventory: Words and Sentences, the KOFA (Kommunikativ Fejlo&huml;desi Adatlap), was given to 90 Hungarian-speaking children aged 12 to 30 months over the course of a year. Growth curve modeling was used to estimate the average trajectory of vocabulary development. Hungarian vocabulary growth is best described using a one-parameter quadratic function. The acceleration of vocabulary growth was positively affected by household income, but this effect disappeared when parental education was controlled for. The results from the lexical class study were surprising. The Hungarian KOFA noun ratio approximated the English CDI noun ratio and surpassed the Mandarin CDI noun ratio among children matched for vocabulary size. The developmental picture, however, reflected trends observed in other languages, with a precipitous drop in the noun ratio from 16 to 21 months of age followed by a gradual deceleration. These findings underscore the importance of examining development through longitudinally-designed studies and analyzing change with the appropriate statistical methods.

520 # $a In order to answer these questions, the Hungarian adaptation of the MacArthur-Bates Communicative Development Inventory: Words and Sentences, the KOFA (Kommunikativ Fejlo&huml;desi Adatlap), was given to 90 Hungarian-speaking children aged 12 to 30 months over the course of a year. Growth curve modeling was used to estimate the average trajectory of vocabulary development. Hungarian vocabulary growth is best described using a one-parameter quadratic function. The acceleration of vocabulary growth was positively affected by household income, but this effect disappeared when parental education was controlled for. The results from the lexical class study were surprising. The Hungarian KOFA noun ratio approximated the English CDI noun ratio and surpassed the Mandarin CDI noun ratio among children matched for vocabulary size. The developmental picture, however, reflected trends observed in other languages, with a precipitous drop in the noun ratio from 16 to 21 months of age followed by a gradual deceleration. These findings underscore the importance of examining development through longitudinally-designed studies and analyzing change with the appropriate statistical methods.
520 # $a The specific questions addressed are: (1) What are the group and individual growth trajectories for Hungarian vocabulary development? (2) How do growth trajectories vary by gender, parental education, and parental income? (3) Do the early words produced by young Hungarian speakers differ in terms of lexical class from those reported in research on English-speaking children? (4) Do Hungarian children produce a greater proportion of nouns than verbs in their early speech?
520 # $a Two of the most fascinating characteristics of human beings are that we develop over time and that we differ from each other. As students of complex human behavior, developmental psychologists often pose questions about these very subjects: growth and variation. In the field of language acquisition research, however, studies of individual growth often overlook variation, while studies of variation rarely take a truly longitudinal perspective. This study aims to address this gap by examining within-language differences in vocabulary development among young Hungarian speakers. The results from this longitudinal analysis, in turn, inform a cross-linguistic comparison of lexical class development.
