Preferential looking at stimuli varying in temporal frequency was examined in 11 prematurely born infants. The relationship between amount of looking and stimulus frequency yielded a significant linear trend with the fastest frequency used (4 hertz) being most preferred. (Author/DB)

Results of the study involving 14 hyperactive boys (5-12 years old) indicated that activity and attention span are affected by methylphenidate even in highly stimulating, informal settings. (Author/SBH)

Describes a study that examined the classroom behavior and reading achievement of elementary school children placed on the Feingold food additive elimination diet. Concludes that children who remained on the diet for six months became less impulsive but did not raise their reading scores significantly. (FL)

Cultural differences in selective attention amonq Ibo and Yoruba adolescents of Nigeria were examined with the auditory split-span technique. (Author/DB)

The development of capacity for attention was assessed by giving children 5, 8, 9, and 12 years of age a component-selection task with instructions to attend to one component or another, or with no specific instructions regarding the stimuli. (CM)

Examined age-related changes in visual selective attention--ability to resist interference--in children 5 to 12 years old and adults. The interference effect on stimulus evaluation did not discriminate between age groups; however, the interference effect on correct response activation showed a pronounced age-related reduction, suggesting a…

Relations between infant information processing and specific cognitive outcomes at age 11 years were examined in a sample of preterm and full-term infants. Seven-month visual recognition memory and 1-year cross-modal transfer predicted 11-year intelligence quotient (IQ). (MDM)

Quantitative measures were made of the fundamental frequency patterns of Japanese mother's speech addressed to infants aged 0;3-0;4. Frequency ranges were found to change with repeated attempts to get the infant's attention but were not otherwise altered substantially from normal adult patterns when an initial attempt was made to gain the infant's…

Tests the proposition that message structure (cuts) affects attention to television differently, depending on whether the cuts link related or unrelated content. Finds cuts in unrelated sequences require more attention than cuts in related sequences. (NH)

In this study, a system was designed for monitoring learning progression and observing how an instructor directs a student's attention toward goals, such as landmarks and shorelines, on mobility routes. Results indicate the system was effective in monitoring the learning progression of 16 students (ages 3-14) with blindness. (Contains references.)…

Weekly observations documented developmental changes in mother-infant face-to-face communication between birth and 3 months. Developmental trajectories for each dyad of the duration of infant facial expressions showed a change from the dominance of Simple Attention (without other emotion expressions) to active and emotionally positive forms of…

This study examines the processing of a specific linguistic distinction, the mass/count distinction, in patients suffering from Alzheimer's disease (AD) and mild cognitive impairment (MCI). Fourteen AD and 10 MCI subjects were tested using a sentence grammaticality judgement task where grammaticality violations were caused by determiner--noun…

Using Ecological Systems Theory and stage sequential modelling procedures for detecting mediation, this study examined how early developmental contexts impact preschoolers' performances on a measure of sustained attention and impulse control. Data from 1273 European-American and African-American participants in the NICHD Study of Early Child Care…

This follow-up study compares cognitive and language aspects of a group of Italian children ages 4-6 years, who had shown delayed expressive language abilities at 24 months of age (late talkers), with those of a group of children with a history of normal expressive language development (average talkers). Children were given a battery of…

The present work investigated cognitive, linguistic and narrative abilities in a group of children suffering from Duchenne Muscular Dystrophy, an allelic X-linked recessive disorder caused by mutations in the gene encoding dystrophin. The patients showed mildly reduced IQ with lower Verbal than Performance Intelligence Quotient and were mildly…
