Preschool Minority Children's Persian Vocabulary Development: A Language Sample Analysis.

This study linked background TV and socioeconomic status (SES) to minority children's Persian vocabulary development. To this end, 80 Iranian preschool children (aged 5-6 years old) from two minority groups of Arabs and Turks were selected using stratified random sampling. They were simultaneous bilinguals, i.e., their mother tongue was either Arabic or Azari and their first language was Persian. Language sample analysis (LSA) was used to measure vocabulary development through a 15-min interview by language experts (PhD in applied linguistics). The LSA measures included total number of utterances (TNU), total number of words (TNW), total number of new words (NDW), and mean length of utterance (MLU). A series of independent-samples test, paired-samples test, and repeated measures MANOVA tests were ran to examine data. Results showed significant improvements in children's vocabulary scores from pretest to posttest for all children. In addition, high-SES children scored higher on the vocabulary measures in pretest and posttest. Moreover, background TV was associated with higher means in the TNW and the NDW in groups. The researchers concluded that background TV may be related to higher vocabulary scores in low-SES families as it may compensate for some linguistics gaps in these families including lower amount of child-parent interaction, play, and parents' level of literacy.
