Effects of beta blockade with metoprolol on simple and complex task performance

The effect of treatment with the beta-blocker metoprolol on several indicants of task performance was investigated. Twenty-five male hypertensives were treated for 2 weeks each with drug and placebo in a double-blind crossover design. Comparisons to 25 matched untreated normotensives were made. Participants responded twice to a Mood Adjective Check List (MACL) and the Stroop Color-Word Test. In addition, they participated in two parallel decision-making simulations. Normotensives and hypertensives on drug or placebo did not differ on MACL and Stroop scores. Comparisons on 12 validated simulation measures showed that drug treatment with metoprolol aided complex task performance. Drug treatment improved strategic capacity and the ability to deal effectively with emergencies. Preliminary evidence that treatment with metoprolol might help restore performance capacity that may have been lost due to hypertensive disease was also obtained.

Discriminating adults' genuine,imagined, and deceptive accounts of positive and negative childhood events

We examined the qualitative characteristics of genuine, imagined, and deceptive accounts of positive and negative childhood events. We investigated whether trained raters could discriminate between these accounts using the Memory Characteristics Questionnaire (MCQ; Johnson, Foley, Suengas, & Raye, 1988) and the Aberdeen Report Judgment Scales (ARJS; S. L. Sporer, paper presented at the biennial meeting of the American Psychology‐Law Society in Redondo Beach, California, March 1988 ). Participants generated three accounts. The first account was of an event that participants genuinely experienced in childhood. The second account was of an event that participants did not experience, but merely imagined happened in childhood. The third account was of an event that participants did not experience, but wrote a deceptive account to convince someone else that the event really happened in childhood. Half our participants wrote about positive events and half wrote about negative events. Ratings made by two trained judges indicated that genuine, imagined, and deceptive accounts were qualitatively different on both the MCQ and ARJS. Moreover, based on the MCQ and ARJS scores raters could discriminate whether the events had been genuinely experienced. We discuss the theoretical and practical implications of these findings.
