A growing body of research has emphasized the linkage between performance in immediate serial recall of lists, nonword repetition, and word learning. Recently, it has been reported that primacy and recency effects are obtained in repetition of individual syllables within nonwords (Gupta, in press). Five experiments examined whether such within -nonword(More)
Twelve experiments examined the effect of neighborhood density on repetition latency for nonwords. Previous reports have indicated that nonwords from high density neighborhoods are repeated with shorter latency than non-words from low density neighborhoods (e.g., Vitevitch & Luce, 1998). Experiment 1 replicated these previously reported results; however,(More)
Research is continually expanding the empirical and theoretical picture of embodiment and dynamics in language. To date, however, a formalized neural dynamic framework for embodied linguistic processes has yet to emerge. To advance embodied theories of language, the present work develops a formalized neural dynamic framework of spatial language that(More)
Substance use in childhood and adolescence is one of the foremost public health concerns for this age range in the U.S. While research indicates that substance use by children and adolescents has declined over the past five years, 49.1% of students still report that they have used illicit drugs during high school [1]. Over the past twenty years, extensive(More)
Study of the phonological similarity effect (PSE) in immediate serial recall (ISR) has produced a conflicting body of results. Five experiments tested various theoretical ideas that together may help integrate these results. Experiments 1 and 2 tested alternative accounts that explain the effect of phonological similarity on item recall in terms of feature(More)
— For an autonomous robotic system, the ability to share the same workspace and interact with humans is the basis for cooperative behavior. In this work, we investigate human spatial language as the communicative channel between the robot and the human, facilitating their joint work on a tabletop. We specifically combine the theory of Dynamic Neural Fields(More)
We describe a set of pictorial and auditory stimuli that we have developed for use in word learning tasks in which the participant learns pairings of novel auditory sound patterns (names) with pictorial depictions of novel objects (referents). The pictorial referents are drawings of "space aliens," consisting of images that are variants of 144 different(More)
We propose a neural dynamic model that specifies how low-level visual processes can be integrated with higher level cognition to achieve flexible spatial language behaviors. This model uses real-word visual input that is linked to relational spatial descriptions through a neural mechanism for reference frame transformations. We demonstrate that the system(More)
This study investigates whether inductive processes influencing spatial memory performance generalize to supervised learning scenarios with differential feedback. After providing a location memory response in a spatial recall task, participants received visual feedback showing the target location. In critical blocks, feedback was systematically biased(More)
