Test (WCST Heaton, Chelune, Talley, Kay, Curtiss, 1993), Category Test and Trail Making Tests (Reitan Wolfson, 1985), Stroop Test (Stroop, 1935), and other tests developed by R. M. Ruff that bear his name. There are many newer ones that may be appropriate to use as well, depending upon the suspected problem you want to assess. Some of these neuropsychological tests can be self-administered, either on a computer or by paper and pencil. However, many of these tests must be administered and results interpreted by a highly trained therapist, usually a clinical psychologist.

Cognitive Tests. Schroeter et. al. studied hemodynamic responses to classic Stroop task where mismatch in words spelling out various colors [93]. The task consisted of two rows and were asked to decide whether the color of the top row of letter corresponded with the bottom row spelling out a color. Three types of stimuli were presented, (1) neutral, where top row consisted of X s, (2) congruent, where top row...

Compared with focused attention, fewer studies have examined the effects of benzodiazepines on selective attention. Two studies have shown that performance on the Stroop test was impaired by lorazepam.119 131 Acute administration of triazolam and lorazepam produced dose-dependent decrements in response rate and accuracy in a simultaneous matching-to-sample task, which required subjects to determine which of two comparison visual stimuli was identical to the sample stimulus.148 161 The drug effects differed as a function of task difficulty, such that the benzodiazepine-induced impairment was reduced when discriminability of the non-matching stimulus was increased.
