Proximity attitudes toward objects and people: reference to a category and a self-representation?

The relative strength of similarity to self and category typicality as predictors of proximity attitudes (social distance) toward people of varying race and objects associated with people of varying race was investigated. Similarity to self and category typicality were significant predictors of proximity attitudes toward both objects and people, but similarity to self was the significantly stronger predictor. The predictive utility of similarity to self was greater for object judgments than person judgments, but category typicality was a better predictor of person judgments than object judgments. Although the results provide evidence of ingroup favoritism in proximity attitudes toward people, the ingroup bias did not extend to objects associated with people. Category typicality was positively related to attitudes, even for distanced groups. The role of predictability of the target in determining proximity attitudes is discussed.     

Mock Juror Judgment and the Insanity Plea: Effects of Incrimination and Sanity information1

Mock jurors were given information about a stabbing incident which varied in incrimination value (high or low) and a psychological profile of the perpetrator which varied in the degree of indicated insanity (high, medium, or low) in four replications of a 2 × 3 design. In one replication, the information was presented in the context of a sanity hearing where guilt was not an issue. In three other replications, the context was a criminal trial in which the defendant pleaded not guilty on the facts, not guilty by reason of insanity (NGI), or both. Judgments in the insanity plea replication were significantly affected by incrimination information even though sanity is legally the only issue. Insanity information predictably affected judgments in the sanity hearing but had only weak effects in the insanity plea context. It was concluded that the judgment dimension which equates insanity with not guilty results in a conflict which subjects resolved by viewing the dimension as more of a guilt dimension.     

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.
