From an operant perspective, verbal behavior is multiply controlled by different sources of stimulation, including self-stimulation. Self-stimulation (i.e., responding with respect to one's own response products) is thought to be especially important for verbal mediation that temporally extends discriminative stimulus control. While previous…

Recent research suggests that performance on Statistical Learning (SL) tasks may be lower in children with dyslexia in deep orthographies such as English. However, it is debated whether the observed difficulties may vary depending on the modality and stimulus of the task, opening a broad discussion about whether SL is a domain-general or…

Three experiments examined the immediate free recall (IFR) of auditory-verbal and visuospatial materials from single-modality and dual-modality lists. In Experiment 1, we presented participants with between 1 and 16 spoken words, with between 1 and 16 visuospatial dot locations, or with between 1 and 16 words "and" dots with synchronized…

Thirty normal geriatric individuals, who had been randomly assigned to one of three feedback modes, were instructed to produce a phrase at slow, average, and fast speaking rates. Results suggest that visual-verbal and verbal-quantitative feedback lead to significantly better performance than verbal-qualitative feedback, particularly when the task…

Examines life-span developmental differences in spontaneous integration of semantically relevant material presented in pictures and sentences. Elementary school students, high school students, and adults were tested. (Author/SS)

Four experiments were carried out to examine the different recall strategies employed in a diagnostic test of visual sequential memory. The principal implication of the results is that good and poor readers may not differ with respect to visual memory but in their ability to employ a verbal labeling strategy. (Author/KC)

This paper presents Skinner's (1957) analysis of verbal behavior as a framework for understanding language acquisition in children with autism. We describe Skinner's analysis of pure and impure verbal operants and illustrate how this analysis may be applied to the design of communication training programs. The picture exchange communication system…
