The latency and amplitude of the P300, an event-related potential, during the performance of a memory-scanning task were used as indices of the efficiency of information processing that may mediate individual differences in intelligence. Results with 61 female college students contradict a pure speed of processing explanation of the relationship…

Describes experimental approaches used to demonstrate perception without awareness. Maintains that experimental findings based on all four approaches lead to the conclusion that stimuli are perceived even when observers are unaware of the stimuli. Asserts that future research should assess the functions of information perceived without awareness…

Presents the results of a two-wave experiment designed to examine how journalistic news frames can facilitate the communication of advocacy frames (to undergraduate students) designed to influence audience perceptions of a political issue. Discusses the implications of these results for journalism, issue advocacy, and the study of issue framing.…

Used shift-rate recovery method in three experiments to examine extent to which 6-month-olds find perceptual cues such as density and length useful in discrimination of linearly arranged sets of large numbers of objects. Found that infants can discriminate between large number sets by relying on absolute cues such as density and on relative cues…

Focuses on the proper place of interlanguage pragmatics in the realm of second-language acquisition (SLA). This introductory essay describes the thematic issue of the ensuing articles as an endeavor to move interlanguage pragmatics more closely toward the center of SLA. The research suggests that many aspects of pragmatic competence can be…

This study tested the hypothesis that there is a developmental shift in the perceptual weighting of acoustic parameters that results from experience with a native language. Comparison of 17 3-year olds and 16 adults found that age-related differences in auditory sensitivity did not fully account for age-related differences in perceptual weighting…

In asking whether certain forms of professionalism are unsuitable for adventure education, the point is made that our professionalism is based on our world view. Compares elemental and city-capitalism world views, and discusses ideal types of professionalism: bureaucratic, vocational (liberational), and relatedness-diversity. Suggests that…

A serious teacher shortage is causing some school leaders to reconsider differentiated staffing within the teaching profession--the idea that individuals with differing levels of expertise and different titles can enhance other staff's effectiveness. Higher salaries and publicly disclosed diplomas and licenses are essential. (MLH)

Modifies and validates a new form of the College and University Classroom Environment Inventory (CUCEI) and uses it to compare students' actual and preferred perceptions of their classroom environments at the senior secondary and tertiary education levels. Examines differences in perceptions according to student gender. (Contains 50 references.)…

Studied the effects of 120 hours of chess instruction on the mathematics achievement of southern, rural, black secondary students. Analysis of covariance results show the treatment group (11 females, 9 males) scored significantly higher than the control group (10 females, 10 males) in mathematics achievement. Discusses results in terms of altering…

A study examined memory for pictures and words in 16 adults with mental retardation and 24 controls. Pictorial superiority effects occurred in free recall and recognition for both intelligence-level groups. Correlational analyses indicated working memory span was primarily related to recall performance, irrespective of stimulus format. (Contains…

The short-term verbal memory performance of 19 children and young adults with Down syndrome (DS) was contrasted with that of two control groups. Results confirm the expected verbal short-term memory deficit in DS subjects and suggest that this deficit is specific to memory for verbal information and is not primarily caused by auditory or…

Investigated 7-month olds' ability to relate vowel sounds with objects when intersensory redundancy was present versus absent. Found that infants detected a mismatch in the vowel-object pairs in the moving-synchronous condition but not in the still or moving-asynchronous condition, demonstrating that temporal synchrony between vocalizations and…

Two experiments examined the effects of a culture-general factor, pattern redundancy, on the discrimination of five-tone melodies that differed in their adherence to Western tonal conventions, among 9-month olds, 5-year olds, and adults. Increasing exposure seemed to attenuate the effects of the pattern redundancy while amplifying the influence of…

Offers a cognitive perspective on the comprehension problems of second language listeners by identifying real-time listening difficulties faced by English-as-Second-Language learners and examining these difficulties within the three-phase model of language comprehension proposed by Anderson (1995). Shows ten problems that occurred during the…
