Porter, Heather L.; Spitzer, Emily R.; Buss, Emily; Leibold, Lori J.; Grose, John H. – Journal of Speech, Language, and Hearing Research, 2018
Purpose: This experiment sought to determine whether children's increased susceptibility to nonsimultaneous masking, particularly backward masking, is evident for speech stimuli. Method: Five- to 9-year-olds and adults with normal hearing heard nonsense consonant-vowel-consonant targets. In Experiments 1 and 2, those targets were presented between…

Ostvik, Leni; Eikeseth, Svein; Klintwall, Lars – Analysis of Verbal Behavior, 2012
This study replicated and extended Wright (2006) and Whitehurst, Ironsmith, and Goldfein (1974) by examining whether preschool aged children would increase their use of passive grammatical voice rather than using the more age-appropriate active grammatical construction when the former was modeled by an adult. Results showed that 5 of the 6…

The Development of Verbal and Visual Working Memory Processes: A Latent Variable Approach
Peer reviewed Peer reviewed
Direct linkDirect link
Koppenol-Gonzalez, Gabriela V.; Bouwmeester, Samantha; Vermunt, Jeroen K. – Journal of Experimental Child Psychology, 2012
Working memory (WM) processing in children has been studied with different approaches, focusing on either the organizational structure of WM processing during development (factor analytic) or the influence of different task conditions on WM processing (experimental). The current study combined both approaches, aiming to distinguish verbal and…

Sidener, Tina M.; Carr, James E.; Karsten, Amanda M.; Severtson, Jamie M.; Cornelius, Carly E.; Heinicke, Megan R. – Analysis of Verbal Behavior, 2010
The purpose of this series of experiments was to evaluate the effects of mixed mand-tact arrangements on the acquisition of mands and tacts in preschool-aged children. In Experiment 1, the effects of three training arrangements (mand-only training, tact-only training, and mand-tact training) were investigated with 3 typically developing children.…

LaFrance, Danielle; Wilder, David A.; Normand, Matthew P.; Squires, James L. – Analysis of Verbal Behavior, 2009
The current study examined the effectiveness of an experimental functional analysis for assessing the functions of emergent vocal-verbal behavior in children with developmental disabilities. Experiment 1 consisted of a systematic replication of Lerman et al. (2005). Participants were 3 children with developmental disabilities, between the ages of…
