Reaction time and general intellectual ability: The effects of cues on the relationship
This study examined the relationship between reaction time (RT) and intelligence. Fifteen female and nine male caucasian undergraduates and one black male undergraduate ranging in age from 19 to 38 served as subjects. The measure of intelligence was the Otis-Quick Scoring Mental Ability Test. An …

Skin conductance and reaction time correlates of learning disability in children
… were compared during an habituation task and a simple reaction time task, each preceded by a rest period. The two tasks were methodologically equivalent except that only the latter required an active response. LDs had more rapid decline of basal conductances during rest, more rapid habituation …

Exposure to Volatile Organic Compounds and Effect on Neurobehavioral Function.
… Neurobehavioral function was assessed by simple reaction time test (SRTT), symbol digit substitution test (SDST), and serial digit learning test (SDLT). Prevalence of exposure to VOC products was, for instance, air freshener/room deodorant - 34.7%, gasoline - 29.2%, finger nail polish - …
