Less Versus More: The Effect of Recast Length in Treatment of Grammatical Errors.

Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of clinicians' recast length on child learning during a recast treatment.

Developmental changes in retention and generalization of nonadjacent dependencies over a period containing sleep in 18-mo-old infants.

Sleep promotes the stabilization of memories in adulthood, with a growing literature on the benefits of sleep for memory in infants and children. In two studies, we examined the role of sleep in the retention and generalization of nonadjacent dependencies (NADs; e.g.

Sleep confers a benefit for retention of statistical language learning in 6.5month old infants.

Infants show robust ability to track transitional probabilities within language and can use this information to extract words from continuous speech. The degree to which infants remember these words across a delay is unknown. Given well-established benefits of sleep on long-term memory retention in adults, we examine whether sleep similarly facilitates memory in 6.
