This study modeled vocabulary trajectories in 91 English language learners (ELLs) with Punjabi, Tamil, or Portuguese home languages, and 50 English monolinguals (EL1) from Grades 1 to 6. The concurrent and longitudinal relationships between phonological awareness and phonological short-term memory and vocabulary were examined. ELLs underperformed…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

Segalowitz and Segalowitz distinguish between "speedup" (mean reaction time [RT] and mean standard deviation of responses in an RT task decrease to the same degree) and "automatization" (mean standard deviation decreases more than mean RT). The coefficient of variation, which is the standard deviation divided by the mean RT, decreases in the case…

The English second language development of 19 children (mean age at outset = 5 years, 4 months) from various first language backgrounds was examined every 6 months for 2 years, using spontaneous language sampling, parental questionnaires, and a standardized receptive vocabulary test. Results showed that the children's mean mental age equivalency…

Investigates developmental association between nonword repetition performance and vocabulary knowledge by evaluating the role of phonological memory and linguistic factors in nonword repetition. (29 references) (GLR)

Reports on a longitudinal study that investigated the claim that phonological memory contributes to vocabulary acquisition in young children. Findings show support for the claim that the capacity component of nonword repetition contributes directly to vocabulary in young children. (Author/VWL)

Examined the relationship between caregiver input to 9-month-old infants and their subsequent language. Mother-infant dyads were videotaped at ages 9, 12, and 30 months. Language comprehension was measured by parent report and correlated with an independent language measure. Found that the total number of words mothers used when their infants were…

Examined longitudinally the handshape aspect of American Sign Language signs in young children of deaf parents. Parents demonstrated on videotape how the children formed the different signs. Findings reveal that four basic handshapes predominated in early sign production, and that the part of the hand involved in contacting a sign's location often…

Examined the strength of the association between language exposure estimates and vocabulary learning for simultaneous bilingual infants with differing patterns of exposure to the languages being learned. Findings revealed that the correlation was strong, even for children whose language environments changed by more than 20% between observations.…

In this longitudinal study, reading acquisition was related to phonological sensitivity and rapid naming in young children. Phonological assessment consisted of rhyme and initial consonant discrimination, whereas rapid naming tasks were made up of pictures, letters, and numbers. Subjects were 95 children from two grade levels, primary and grade…

Three discourse-related formal aspects of model-imitation pairs were analyzed longitudinally in successive samples from two Hungarian children. Results revealed an unbroken developmental trend leading to lexically coherent conversational replies and that imitation aided the children in learning the lexicon, making phonological approximations of…
