Alcohol and Secobarbital: Effects on Information Processing
Most published reports of the effects of drugs on human performance have been empirical and task specific rather than theoretical in conception. For example, alcohol and secobarbital both cause impairment on tasks such as time estimation (Rutschman & Rubenstein, 1966), reaction time (Moskowitz & Roth, 1971; Blum, Stern & Melville, 1964) and verbal retention (Jones, 1973; Evans & Davis, 1969). Yet, alcohol and the barbiturates are not identical, pharmacologically; and it is important to discover whether their similar effects on laboratory tasks result from impairment of different or of the same cognitive processes. One way to address this question is to examine drug effects from the perspective of an information processing model.
