The present study sought to determine if the postural sway of a subject required to grasp a tray (motor task) holding a cup filled with water and prevent spilling (mental task), would be reduced by consciously redirecting attention to maintain the tray in a horizontal position. We hypothesized the mental task would increase the stabilization of standing postural balance. Postural sway was measu...

this article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of english as a foreign language (efl). the study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was aff...

Science and engineering students must learn to rotate mentally complex objects in order fully to understand much of the subject matter in standard courses. These mental rotation tasks are surprisingly difficult for a large number of such students. The performance of science and engineering students in a particularly difficult mental rotation task is being analyzed for the purpose of discovering...

It is well established that performance on standard mental rotation tasks improves with training (Peters et al., 1995), but thus far there is little consensus regarding the degree of transfer to other tasks which also involve mental rotation. In Experiment 1, we assessed the effect of mental rotation training on participants' Mental Rotation Test (MRT) scores. Twenty-eight participants were ran...

investment information is rapidly and efficiently diffused. New product and service innovations, be they junk bonds, new forms of options, or debt securities that allocate and price risk in an innovative fashion, get rapidly copied by competitors. But in the “managerial knowledge” marketplace, there is little evidence of much diffusion of ideas or innovative business models and management pract...

Rectangular geometrical patterns with equal number of lines, identical relations between their vertical and horizontal components, identical angles, line crossing knots and free ends of lines were presented tachistoscopically to human subjects with a restricted recognition time caused by backward masking. Symmetrical linear transformation with respect to the Y or X axes and rotations of the pat...

The goal of this project was to examine how training either mental or manual (virtual) rotation, affects performance gains on either a mental or a manual rotation task. In Experiment 1, we examined improvement on a manual rotation task following practice in mental rotation, manual rotation and a control condition. Practice in mental but not manual rotation lead to improved performance on manual...

In 2004, the American Academy of Pediatrics (AAP) Board of Directors formed the Task Force on Mental Health and charged it with developing strategies to improve the quality of child and adolescent mental health* services in primary care. The task force acknowledged early in its deliberations that enhancing the mental health care that pediatricians and other primary care clinicians† provide to c...

This study examined the effects of age and sex on mental rotation performance, verbal performance, and brain-wave activity. Thirty-two 8-year-olds (16 boys) and 32 college students (16 men) had EEG recorded at baseline and while performing four computerized tasks: a two-dimensional (2D) gingerbread man mental rotation, a 2D alphanumeric mental rotation, of three-dimensional (3D) basketball play...
