Associative interference: effects of meprobamate on normal adult's performance on a Müller-Schümann type learning task

Performance decrement after intake of meprobamate as a function of task difficulty and learning level

The effect of 800 mg of meprobamate on performance in choice-reaction tasks of varying difficulty was examined. Comparisons between scores obtained in drug and placebo conditions showed that performance was progressively more impaired by the drug as task difficulty increased and progressively less impaired as learning level increased.
