The study with 989 learning-disabled students supported the cognitive-based arithmetic problem-solving model of Dinnel et al. under continuous visual stimulus conditions but suggested a more complex neuropsychological underpinning to arithmetic performance in both visual and aural stimulus conditions.

The study investigated two neurophysiologic components of event-related brain potential during auditory and visual target detection tasks with 11 non-retarded autistic children, 9 retarded autistic children, and 16 normal subjects, aged 15-19. Results were consistent with the hypothesis that non-retarded autism involves abnormal attentional and…

Eight tactile-kinesthetic indices and 27 cognitive-ability and mental-speed measures were administered to 195 college students and community members. Results suggest that tactile-kinesthetic abilities share much with broad visualization and fluid intelligence, little with crystallized intelligence, and differential relationships with speed related…

This study compiled a comprehensive early auditory processing skills assessment battery and evaluated the battery to toddlers with (n=8) and without (n=9) early recurrent otitis media. The assessment battery successfully distinguished between normal and deficient early auditory processing development in the subjects. The study also found parents…

The shortcomings of the dominant information processing models of cognition are outlined, and two alterative models derived from semiotics are presented. In addition, the possibility of incorporating J. J. Gibson's ecological theory of affordance within the semiotic models is explored as a means of addressing some criticism of the latter models.…

Discusses research that may broaden understanding of how music of other styles and cultures is perceived and remembered. Experiments examined serve to isolate similarities and differences that exist across musical cultures and characterize their psychological effects and to study perception of compositional styles in Western music outside the…

A LITERATURE REVIEW OF SIX KEY CONCEPTS OF PSYCHOLINGUISTIC PROCESSES IS PRESENTED. THE SIX CONCEPTS ARE (1) COGNITIVE GROWTH, (2) PSYCHOLINGUISTIC MODELS SUCH AS THE ILLINOIS TEST OF PSYCHOLINGUISTIC ABILITIES (ITPA), (3) INTERSENSORY INTEGRATION, (4) REMEDIAL TEACHING TECHNIQUES, (5) VISUALIZATION IN INTEGRATIVE TASKS, AND (6) CONCEPTUAL SCHEMA.…

At the level of clinical speech/language evaluation, the repetition type of conduction aphasia is characterized by repetition difficulties concomitant with reduced short-term memory capacities, in the presence of fluent spontaneous speech as well as unimpaired naming and reading abilities. It is still unsettled which dysfunctions of the…

Object recognition research is typically conducted using 2D stimuli in lieu of 3D objects. This study investigated the amount and complexity of knowledge gained from 2D stimuli in adult chimpanzees ("Pan troglodytes") and young children (aged 3 and 4 years) using a titrated series of cross-dimensional search tasks. Results indicate that 3-year-old…

Two experiments investigated whether motion metaphors for time affected the perception of spatial motion. Participants read sentences either about literal motion through space or metaphorical motion through time written from either the ego-moving or object-moving perspective. Each sentence was followed by a cartoon clip. Smiley-moving clips showed…

In this study, the authors investigated how salient visual features capture attention and facilitate detection of emotional facial expressions. In a visual search task, a target emotional face (happy, disgusted, fearful, angry, sad, or surprised) was presented in an array of neutral faces. Faster detection of happy and, to a lesser extent,…

Central Auditory Processing (CAP) difficulties have attained increasing recognition leading to escalating rates of referrals for evaluation. Recognition of the association between (Central) Auditory Processing Disorder ((C)APD) and language, learning, and literacy difficulties has resulted in increased referrals and detection in school-aged…

Harmonic priming studies have shown that a musical context with its tonal center influences target chord processing. In comparison with targets following baseline contexts, which do not establish a specific tonal center, processing is facilitated for a strongly related target functioning as the tonic, but inhibited for unrelated (out-of-key) and…

Studies investigating changes in functional cerebral asymmetries (FCAs) with hormonal fluctuations during the menstrual cycle in young women have led to controversial hypotheses about an influence of estrogen (E) and/or progesterone (P) on FCAs. Based on methodical, but also on principal problems in deriving conclusions about hormone effects from…

Background: Recent reports showed that children born with intrauterine growth restriction (IUGR) are at greater risk of experiencing verbal short-term memory span (STM) deficits that may impede their learning capacities at school. It is still unknown whether these deficits are modality dependent. Methods: This long-term, prospective design study…
