Superior visual attention skills are vital for excellent sports performance. This study used a cognitive skills approach to examine expert and novice differences in a visual spatial attention task. Thirty-two males aged 18 to 42 years completed this study in return for course credit or monetary incentive. Participants were expert golfers (N = 18) or exercise controls (N = 14). Spatial attention...

Procedures for training pigs by shock avoidance conditioning to perform a shuttlebox and a visual discrimination problem are described. Pigs achieved stable performance levels of better than 95 percent shock avoidance in 6 and 35 days for the shuttlebox and discrimination problem, respectively. Such stable and accurate performances are required for assessing behavioral effects of independent va...

Attention plays a fundamental role in visual learning and memory. One highly established principle of visual attention is that the harder a central task is, the more attentional resources are used to perform the task and the smaller amount of attention is allocated to peripheral processing because of limited attention capacity. Here we show that this principle holds true in a dual-task setting ...

the aim of the present study was to find out whether training in a specific visual condition was an advantage in learning the accuracy of skill performance in the basketball free throw shooting. 28 boys (mean age: 17.14+0.75 years) voluntarily participated in the study and practiced in two groups: with normal light (control group), and in a specific visual condition (focusing light on rim of ba...

introduction: the term dynamic assessment (da) refers to an assessment, by an active teaching process, of a child's perception, learning, thinking, and problem solving. the process is aimed at modifying an individual's cognitive functioning and observing subsequent changes in learning and problem-solving patterns within the testing situation. da has been advocated as an alternative an...

purpose : to investigate the discriminative ability of contrast sensitivity (cs), color vision and best corrected visual acuity (bcva) in detecting functional losses in diabetic participants with and without retinopathy methods : in this cross sectional study we examined 105 patients in khatam-al-anbia eye hospital of mashhad university of medical sciences including 70 diabetic patients (35 wit...

Human vision is quantified through the use of standardized clinical vision measurements. These measurements typically include visual acuity (near and far), contrast sensitivity, color vision, stereopsis (a.k.a. stereo acuity), and visual field periphery. Simulator visual system performance is specified in terms such as brightness, contrast, color depth, color gamut, gamma, resolution, and field...

In visual control of motion the performance of the system is typically tied to the speed at which the visual information can be processed. Visual processing is unusual in that the data is not the information and in some sense the quality of the information can often be improved through extended processing (e.g. the resolution). A visual sensor tracking an object will only provide sporadic obser...
