Time perception performance was systematically investigated in adolescents with and without attention-deficit/hyperactivity disorder (ADHD). Specifically, the effects of manipulating modality (auditory and visual) and length of duration (200 and 1000 ms) were examined. Forty-six adolescents with ADHD and 44 controls were administered four duration…

Effects on spoken-word recognition of prevoicing differences in Dutch initial voiced plosives were examined. In 2 cross-modal identity-priming experiments, participants heard prime words and nonwords beginning with voiced plosives with 12, 6, or 0 periods of prevoicing or matched items beginning with voiceless plosives and made lexical decisions…

This research explores the way in which young children (5 years of age) and adults use perceptual and conceptual cues for categorizing objects processed by vision or by audition. Three experiments were carried out using forced-choice categorization tasks that allowed responses based on taxonomic relations (e.g., vehicles) or on schema category…

Total Physical Response (TPR), developed by James Asher, is defined as a teaching technique whereby a learner responds to language input with body motions. Performing a chant or the game "Robot" is an example of a TPR activity, where the teacher commands her robots to do some task in the classroom. Acting out stories and giving imperative commands…

Can learning of mental imagery skills for visualizing shapes be accelerated with feature masking? Chemistry, physics fine arts, military tactics, and laparoscopic surgery often depend on mentally visualizing shapes in their absence. Does working with "spatial feature-masks" (skeletal shapes, missing key identifying portions) encourage people to…

Contemporary culture has become increasingly dependent on the visual, especially for its capacity to communicate instantly and universally. Advances in technology fueled this shift. Students must learn to cope with and intelligently contribute to a culture rife with easy access to the visually rich Web, photo dependant social networks, video…

Computer-assisted teaching and assessment has become a regular feature across many areas of the curriculum in higher education courses around the world in recent years. This development has resulted in the "digital divide" between disabled students and their nondisabled peers regarding their participation in computer-assisted courses. However,…

This paper examines a model of individual ways of learning and its implications for mathematics teaching. Topics discussed include: alternative ways that students use to represent mathematical ideas, management or control mechanisms, related models of learning preferences, ways in which students relate and manipulate ideas, and implications of…

The effects upon initial acquisition, transfer, and retention of mode and sequence of stimulus presentation in self-instructional elementary multiplication lesson sequences were studied with first, second, and third grade students. (Author/CS)

This study explored how, and what type of, procedural instructions influence a trade-off between planning and performance. There is a trade-off if longer planning time shortens performance time, improves performance efficiency, and improves accuracy. The relative effectiveness of nine combinations of illustrated and written instructions for an…

A clinical psychologist describes an approach she uses to assess learning disabled students. She explains that brain function is analyzed through a sequence of tasks charting visual and auditory discrimination, perception, memory, organization, integration, and output. An example is cited in which an 11 year old child with traumatic brain injury…

Teaching approaches for adult English as second language students with little previous formal education or native language literacy cannot rely on the traditional written materials. For students who cannot be reached through the written word, approaches must be devised that engage other channels of perceptions. Classroom activities are suggested…

The class of media characteristics, which is generic to them and which may be of potentially great relevance to learning, is the way in which media select, highlight, structure, and present information, i.e., their "languages" or symbol systems. How, if at all, and why do symbol systems, in general, differentially relate to cognition and learning?…
