Visuomotor performance

Human subjects exposed to 200ppm detected a strong odor, but excessive discomfort was not experienced at 400 ppm, there was strong eye and nasal irritation. Central nervous system effects, such as depression, poor memory, and slow visuomotor performance, have been associated with heavy exposures. ... 

Visuomotor testing has been performed in 76 patients with schizophrenia or a schizophreniform disorder receiving haloperidol (n = 23 mean dose 10 mg/day), olanzapine (n = 26 10.6 mg/day), or risperidone... 

In summary, the above studies show that neurobehavioral evaluation of pesticide workers reveal increased prevalence of neurologic symptoms and changes in neurobehavioral performance indicative of mild cognitive and psychomotor dysfunction. These effects appear to be more prevalent during the period of exposure, but also persist beyond the period of exposure. Total cumulative exposure seems to be a greater risk factor for poor performance than any other covariant. Deficits in visuomotor speed as indexed by the digit symbol substimtion test and the trailmaking tests have been shown to be consistently effected as well as tests of selective attention and memory...

Other measures of cognitive or neurological performance Early research results (Byers and Lord, 1943 Thurston et al, 1955) were interpreted as demonstrating a defect in visuomotor coordination in children who had recovered from lead intoxication. De la Burde and Choate (1972, 1975) reported differences in fine motor coordination in lead-exposed children.
