Neurologically normal individuals exhibit strong leftward response biases during free-viewing perceptual judgments of brightness, quantity, and size. When participants view two mirror-reversed objects and they are forced to choose which object appears darker, more numerous, or larger, the stimulus with the relevant feature on the left side is…

Objective: Deficits in executive functioning, including working memory (WM) deficits, have been suggested to be important in attention-deficit/hyperactivity disorder (ADHD). During 2002 to 2003, the authors conducted a multicenter, randomized, controlled, double-blind trial to investigate the effect of improving WM by computerized, systematic…

Young children often have a preference for auditory input, with auditory input often overshadowing visual input. The current research investigated the developmental trajectory and factors underlying these effects with 137 infants, 132 four-year-olds, and 89 adults. Auditory preference reverses with age: Infants demonstrated an auditory preference,…

The concepts of sky and visibility distance, as perceived by different learners, are investigated for the first time as a subject of a science education research. Mental models of students with regard to the subject were elicited. They were interpreted in terms of two-level hierarchy: schemes and facets-of-knowledge (defined in the paper). Our…

In this article, the authors compare the reading behavior of students with low vision to that of two groups of students with normal vision (reading-match and age-match students). In Experiment 1, students identified the first letter in words and nonwords and the researchers measured latency and accuracy. No group differences were found for…

Sometimes a radical shift in assessment procedures may uncover a whole new set of objectives that neither the students nor the instructor expected. Such an experience is described in the context of freshman mathematics. (Contains 1 table.)

The article discusses music learning through aural, visual and kinesthetic strategies. Most general music teachers are aware of the contributions made to the profession by proponents of the Dalcroze, Kodaly, and Orff approaches to music instruction. It was claimed that students used one of the said strategies as their most efficient way to process…

Here, we demonstrate that action video game play enhances subjects' ability in two tasks thought to indicate the number of items that can be apprehended. Using an enumeration task, in which participants have to determine the number of quickly flashed squares, accuracy measures showed a near ceiling performance for low numerosities and a sharp drop…

The visual system continually selects some information for processing while bypassing the processing of other information, and as a consequence, participants often fail to notice large changes to visual stimuli. In the present studies, the authors investigated whether knowledge about the probability of particular changes occurring over time…

A concurrent-operants design was used to analyze the repetitive behavior of observing reflective surfaces while simultaneously engaging in erratic gross-motor body movements (EBMs) exhibited by a young boy diagnosed with autism. The assessment involved an evaluation of preference for controlled (i. e., the participant controlled the visual…

Two experiments used Muller-Lyer stimuli to test the predictions of the planning-control model (S. Glover, 2002) for aiming movements. In Experiment 1, participants aimed to stimuli that either remained the same or changed upon movement initiation. Experiment 2 was identical except that the duration of visual feedback for online control was…

This study investigated the possibility that the amount of content children include in their stories is affected by how stories are presented. Simple stories were presented to kindergarten and Grade 2 children in 3 conditions: orally (oral only), pictorially (pictures only), and combined oral and pictures. The kindergarteners recalled more content…

Episodic memory (EM) deficits are the hall-mark of Alzheimer's disease (AD). Story-retelling tasks are particularly sensitive to EM impairments and require participants to recall a short story immediately and after a delay. The purpose of this study was to determine whether presentation modality influences story recall in AD participants. Thirty…

Background: Three experiments investigated the role of inner speech deficit in cognitive performances of children with autism. Methods: Experiment 1 compared children with autism with ability-matched controls on a verbal recall task presenting pictures and words. Experiment 2 used pictures for which the typical names were either single syllable or…

The present work aims at demonstrating that visual training associated with the act of reading modifies the way we perceive printed words. As reading does not train all parts of the retina in the same way but favors regions on the side in the direction of scanning, visual word recognition should be better at retinal locations that are frequently…
