Under some conditions, learning is improved by using a dual mode presentation involving for example, visual diagrams and auditory, rather than written text (modality effect). Under other conditions, learning is improved by asking learners to imagine rather than study instructional material (imagination effect). Both effects have been explained…

Purpose: To examine age-related differences in auditory speech recognition and visual text recognition performance for parallel sets of stimulus materials in the auditory and visual modalities. In addition, the effects of variation in rate of presentation of stimuli in each modality were investigated in each age group. Method: A mixed-model design…

The effects of dissonant and consonant music on cognitive performance were examined. Situational dissonance and consonance were also tested and determined as the state where one's opinion is contrasted or matched with the majority's opinion, respectively. Subjects performed several cognitive tasks while listening to a melody arranged dissonantly,…

This paper summarizes the results of a review of the empirical literature (1990-2005) focusing on use of assistive technology as a self-management tool for persons with intellectual disabilities. Forty investigations were identified which provided information on assistive technology to assist persons with disabilities to initiate and complete…

Purpose: This study tests the hypothesis that toddlers with autism spectrum disorders (ASD) will show differences from contrast groups in preferences for attending to speech. Method: This study examined auditory preferences in toddlers with ASD and matched groups of (a) typical age-mates, (b) age-mates with nonautistic developmental disabilities,…

The influence of orthography on children's on-line auditory word recognition was studied from the end of Grade 2 to the end of Grade 4, by examining the orthographic consistency effect [Ziegler, J. C., & Ferrand, L. (1998). Orthography shapes the perception of speech: The consistency effect in auditory recognition. "Psychonomic Bulletin & Review",…

Stimuli used in research on the perception of the speech signal have often been obtained from simple filtering and distortion of the speech waveform, sometimes accompanied by noise. However, for more complex stimulus generation, the parameters of speech can be manipulated, after analysis and before synthesis, using various types of algorithms to…

This study assessed whether redundant stimuli are beneficial in motor performance, and how redundant information is processed, using 11 male and 11 female undergraduate students. A minimum information tracking task was presented to subjects on a computer in seven conditions. Overall, evidence seems to point to enhanced performance when information…

A multi-method approach to the diagnosis of attention deficit hyperactivity disorder was investigated for the purpose of developing an assessment model that could detect the subjects' level of functioning within Mirsky's (1987) four phases of attention and to determine if the primary distractors were by auditory, visual, or combined stimuli.…

Children's temporal comprehension was assessed after viewing a television program containing flashbacks that shifted the events to much earlier times. Flashbacks were marked or not marked with sound effects, and time relations were represented with either dreamy dissolves or abrupt camera cuts. A total of 64 children, equally distributed by sex…

Two studies investigate the way in which children make sense of a play and the visual, aural, and psychological components of theatre which contribute to this comprehension. In the first study, 32 fifth graders saw "Don Quixote of La Mancha." In the second study, 45 third graders saw "Monkey, Monkey" (about the Chinese Monkey King). The day after…

This study considered two questions about infants' perception of affective expressions: (1) Can infants distinguish between happiness and anger on the basis of facial motion information alone? (2) Can infants detect a correspondence between happy and angry facial and vocal expressions by different people? A total of 40 infants of 7 months of age…

Two enduring questions in psychology concern the effects on behavior of traits and of attitudes. One method of altering the relative influence of traits or attitudes is by manipulating the activity of those areas of the brain which attend more to the self or to the external environment. Two experiments were conducted to test whether manipulation…

This study was designed to investigate whether age differences in timesharing performance would be found if the baseline performance of younger and older children was experimentally equated. Two groups of twelve 8-year-olds and one group of twelve 13-year-olds participated. Each subject performed a compensatory tracking task and an auditory…

Twenty-five dysfunctional (either autistic-like or with reading disorders) Ss ranging in age from 2 months to 25 years were studied to determine whether they respond to the same sound more than once. (Author/SB)
