Williams syndrome is a rare neurodevelopmental disorder caused by deletion of approximately 25 genes on chromosome 7q11.23. Children with the syndrome evidence large individual differences in both broad language and reading abilities. Nevertheless, as a group, children with this syndrome show a consistent pattern characterized by relative…

Young adults with a history of specific language impairment (SLI) differ from reading-impaired (dyslexic) individuals in terms of limited vocabulary and poor verbal short-term memory. Phonological short-term memory has been shown to play a significant role in learning new words. We investigated the neural signatures of auditory word recognition…

This paper discusses a mental model of learning based on the processes of attention, perception, processing, and application. The learning process starts with attention, such as curiosity, excitement, expectation, or fear; in pedagogy this is called motivation. New impressions are dependent on and interpreted against the background of previous…

This review of the literature on the workings of the brain in relation to learning and instructional design reviews recent research on both long- and short-term memory, and discusses findings on lateralized or "split-brain" functions. Problems associated with short-term memory are also considered, and the concept of the Tribune Brain is…

Two experiments examining the "distinctiveness of encoding" hypothesis are reported. The hypothesis suggests that specific forms of processing of events may result in the formation of more exact perceptual descriptions and thus more distinctive records in memory. The two experiments reported address shortcomings in previous research on…

Previous research by A. I. Schulman argued that an observed systematic decline in recognition memory in long word lists was due to the build-up of input and output proactive interference (PI). It also suggested that input PI resulted from process automatization; that is, each list item was processed or encoded in much the same way, producing a set…

Several studies have reported adult age deficits in memory for prose materials. Adult age differences in prose comprehension were examined among young and old adults from high or low educational backgrounds. Subjects (N=53) listened to tape-recorded versions of two narrative passages and attempted to orally recall the stories. Subjects were…

In silent reading, short-memory tasks, such as semantic and syntactic processing, require a stage of phonetic encoding between visual representation and the actual extraction of meaning, and this encoding includes prosodic as well as segmental features. To test for this suprasegmental coding, an experiment was conducted in which subjects were…

Compares performance of 172 children aged 7 to 13 years on tasks involving visual or auditory presentation of rhyming and nonrhyming letters and an oral or written response. Results indicate insensitivity to phonological similarity for young children with disabilities; sensitivity improves with age, but deficits in short-term memory remain at…

Examined the effects of age, repetition, and retention interval on children's memory of the final occurrence of a repeated event. Found that repetition increased the number of items recalled, and that younger children showed a poorer ability to discriminate between the occurrences than the older children, though age differences were less evident…

Two studies examined the impact of temporal synchrony on infants' learning of and memory for sight-sound pairs. Findings indicated that 7-month-olds had no difficulty learning auditory-visual pairs regardless of temporal synchrony, remembering them 10 minutes later and 1 week later. Three-month-olds showed poorer learning in no-synchrony than in…

Outlines the current debate regarding the veracity of delayed memories of child sexual abuse, describes the historical context in which this controversy occurs, discusses the growth and development of psychotherapy for trauma survivors, and reviews the theoretical and empirical literature relevant to abuse memories. Presents recommendations for…

Established the differential maturation of rapid-speaking durations and the durations of interword pauses in the memory-span-task responses of first, third and fifth graders. Found that a particular memory span is accompanied by different profiles of processing rates in children of different ages. (Author)

Three experiments examined characteristics of a stimulus-cueing retrieval from long-term memory for 3-month olds. Used mobiles displaying either Qs (feature-present stimuli) or Os (feature-absent stimuli) and tested 24 hours later. Findings indicated that target-distractor similarity constraints, whether or not a feature-present stimulus, would…
