In South Africa for example, both Meyers et al. (2007) and Raiman et al. (2008) report that elderly guardians have practical difficulties in administering ARV medication due to their compromised visual and arithmetic skills.
Repeated measures ANOVA was used to check for effects of BT on cognitive performance in visual search and arithmetic calculation tasks.
Isoboles must be straight lines under GCA, but application of this visual test requires arithmetic x- and y-axes instead of the logarithmic axes commonly used in toxicology.
Relative to their overall performance, WS subjects tended to do well in tests of vocabulary (Vocabulary) and abstract reasoning (Similarities, Picture Arrangement), and poorly in tests of numeracy (Arithmetic), visual-spatial (Digit Symbol, Block Design, Object Assembly), and memory (Digit Span); these subtests are described in Table S1.
Specifically, relative to their overall performance, WS subjects tend to do well in tests of vocabulary (Vocabulary) and abstract reasoning (Similarities, Picture Arrangement), and poorly in tests of numeracy (Arithmetic), visual-spatial (Digit Symbol, Block Design, Object Assembly), and memory (Digit Span) [6].
In this study, we investigated, first, whether verbalizers show activations in areas for language processing, and whether visualizers show activations in areas for visual processing during mental arithmetic.
In the domain of arithmetic, a visual style might mean to visualize numbers and (intermediate) results while calculating or to move mentally along the mental number line.
In the domain of arithmetic, a visual style might for example mean to visualize numbers and (intermediate) results, and a verbal style might mean, that numbers and (intermediate) results are verbally repeated.
The Chinese use of abacuses also makes arithmetic more visual, the authors note.
In addition, when switching from a monotonous to a complex road environment, drivers' performance in visual distance estimation and arithmetic tasks improved though their driving behavior deteriorated, revealing that the fatigue effect upon drivers might be explained to some extent by their alertness and arousal levels.
A decline in performance was also revealed in the tAD group, except on visual memory, letter cancellation, arithmetic, and visuoperceptual processing tests.
