This study tested the procedural deficit hypothesis of specific language impairment (SLI) by comparing children's performance in two motor procedural learning tasks and an implicit verbal sequence learning task. Participants were 7- to 11-year-old children with SLI (n = 48), typically developing age-matched children (n = 20) and younger…

Background: Few investigations have examined the relationship between a comprehensive range of executive functioning (EF) abilities and reading. Aims: Our investigation identified components of EF that independently predicted single word reading, and determined whether their predictive role remained when additional variables were included in the…

Behavioral and neuroimaging findings indicate that distinct cognitive and neural processes underlie solving problems with sudden insight. Moreover, people with less focused attention sometimes perform better on tests of insight and creative problem solving. However, it remains unclear whether different states of attention, within individuals,…

Vocal reaction time of 16 hearing and 25 hearing impaired children (7-14 years old) in response to visually presented stimuli was measured in four tasks. Differences between normal and hearing impaired increased systematically with the phonetic complexity of the task. Hearing level and latency in the counting responses were major predictors of…

Verbal analogy solution is more flexible than is suggested by either the standard process theory or Sternberg's theory. It was determined that subjects initially examine terms A and B; if this strategy is not successful, they examine the relationship between A and C. (Author/CP)

The results of two experiments indicate that the two phonological properties of a word, its initial phoneme and length, strongly influence the latency to detect a target phoneme which begins the following word. Studies showing increased detection latencies following ambiguity are analyzed. (SW)

Authors note that Fehrer and Biederman's two statistical tests were not of equal power and that their conclusion could be a statistical artifact of both the lesser power of the verbal report comparison and the insensitivity of their particular verbal report indicator. (Editor)

Study to determine whether learning is a phenomenon of input processing, output processing, or both. (Author/DS)

Three experiments are reported regarding reaction time. Letter comparison time was found to increase when other irrelevant letters were present, regardless of whether or not the letters made up a word or a word-like configuration. Word comparison time was found to increase when distractors were similar to targets. (Author/RM)

A model is proposed in which information processing is accompanied by dynamic processes, including the reorganization of items into active patterns and their subsequent displacement. Research using category names and instances showed that reaction times decreased with each successive repetition under one condition, but longer latencies were…

Results indicate that Ss have a strong tendency to imitate a model, whether or not the model is reinforced or is successfully learning the task. (Author)

The effects of several factors on expended processing capacity were measured. Expended processing capacity was greater when information was retrieved from secondary memory than from primary memory, when processing was of a deep, semantic nature than when it was shallow and physical, and when processing was more elaborate.

An experiment is described that involved presenting sentences to the subject for study and then testing single words for recognition (the subject had to decide whether the test word was in one of the study sentences). A large priming effect was obtained. (Author/RM)
