Main Outcome Measures: Performance on visual scanning tests involving naming of letters and numbers.
The digit symbol [21] and the visual scanning test from the Delis-Kaplan Executive Function system (D-KEFS) [22] were used to rate attention.
TMT-A, visual scanning test, requires one to draw a line connecting consecutive numbers from 1 to 25. TMT-B, adds cognitive flexibility to TMT-A and requires one to draw a line connecting numbers and letters in alternating sequence.
TMT-A, a visual scanning test, requires one to draw a line connecting consecutive numbers from 1 to 25. TMT-B adds cognitive flexibility to TMT-A and requires one to draw a line connecting numbers and letters in alternating sequence (17).
After logistic regression analysis, side of lesion, kinetic vision, visual scanning, and a road test led to the best model in predicting the team decision (R2 =.53).
Subjects treated with zonisamide in the present study did not exhibit significant changes in performance on a test of attention, visual scanning, and psychomotor speed, or on a test that measures verbal fluency.
The patients also completed a trail-making test of visual scanning, requiring a combination of information-processing speed, manual motor speed, and sustained attention.
He references a study published in the Journal of Environmental Psychology in 1995, titled "Views to Nature: Effects on Attention". Researchers wanted to find out whether or not dorm students with views of beautiful nature scenes would do better on cognitive tests that measured attention, visual scanning and motor speed, over students with more urban views.
Nevertheless, in these children, PCB exposure was related to the number of omission errors on a digit cancellation test, which requires visual selective attention as much as visual scanning and processing speed.
Trail Making B also tests a wide range of cognitive processes, including complex attention, visual scanning, psychomotor speed, and mental flexibility (17).
