This study examines how listener judgments of second language speech relate to individual differences in listeners’ phonological memory, attention control, and musical ability. Sixty native English listeners (30 music majors, 30 nonmusic majors) rated 40 nonnative speech samples for accentedness, comprehensibility, and fluency. The listeners were also assessed for phonological memory (serial re...

Gamma-band activity (GBA) bursts have been viewed as a signature for ignitions in localized Hebbian cell assemblies and are thought to indicate active memory. Using whole-head magnetoencephalography, we recorded focal bursts of GBA during chess playing. Unlike highly skilled chess grandmasters, with amateur chess players focal gamma bursts prevailed in deeper structures in the region of the med...

The theory underlying computerized adaptive tests assumes that all items for a given subtest measure a single dimension. This assumption was examined for the Math Knowledge items in the item pool developed for the Armed Services Vocational Aptitude Battery. Departures from the assumption were found to be minor.

PURPOSE The authors examined whether school-age children with a history of specific language impairment (H-SLI), their peers with typical development (TD), and adults differ in sensitivity to audiovisual temporal asynchrony and whether such difference stems from the sensory encoding of audiovisual information. METHOD Fifteen H-SLI children, 15 TD children, and 15 adults judged whether a flash...

he LanguageNation platform aims to make online language learning more effective and efficient by leveraging the resources of Human Language Technology and Second Language Acquisition research. Part of this goal involves tailoring training to learner profiles at the individual level, which may be accomplished more easily in an online environment than in traditional classroom instruction. Further...

Normative variation in mathematical aptitude (MA) is relevant to many aspects of societal functioning, in particular for occupations in science, technology, engineering and mathematics (STEM). Though elements of numerosity have been identified in some animals, complex MA is uniquely human. Several studies, using a variety of designs, have investigated the heritability of MA, and the extreme end...

An initial cognitive study of early learning of programming aimed to extract experimental test data to establish novices’ understanding process has been carried out by us [1]. This empirical study was inspired by the notion that different people bring different patterns of knowledge in any new learning process, and demonstrated that how each student tackles the problem in a different way based ...
