The acute haemodynamic effects of Italian coffee and 200 mg purified caffeine were investigated in 15 healthy non-coffee-drinkers compared to individuals who consumed placebo (highly decaffeinated coffee for regular coffee, and china bitter extract for caffeine). Before coffee and caffeine consumption and 30, 60, 90 and 120 min afterwards, rest flow and blood pressure were measured, and peripheral resistance in the arm was calculated; an echocardiogram was also performed before and 60 and 120 min after caffeine consumption. Both coffee and caffeine significantly decreased rest flow, and increased peripheral resistance. Systolic blood pressure increased by 10% and diastolic pressure increased by 5% for at least 2 h. No variation in heart rate or cardiac contractility was found. No effects were observed after placebo treatment. It is concluded that Italian coffee and caffeine increase blood pressure via vasoconstriction.

This paper investigated the hypotheses that (a) inferences from behaviors to traits would occur more frequently than vice versa, (b) this induction-deduction asymmetry would be facilitated by stereotype congruence but inhibited by incongruence, and (c) the tendency to draw trait inferences from stereotype-congruent but not from stereotype-incongruent behaviors would become more pronounced with increasing levels of Need for Cognitive Closure. Participants read information about a female or male job applicant that was in part relevant to gender, in part gender-neutral. The gender-relevant information was either stereotype-congruent or incongruent. Half of the information was presented as trait-adjectives, half as behavior-descriptive verbs. A recognition task was constructed so that some of the items (traits and behaviors) had actually been seen, some were entirely new, and some were new but had been implied by the information given. All three hypotheses were supported. Implications for intra-individual and interpersonal stereotype maintenance are discussed.
