On the coagulation of the blood: an elaboration of Lord Lister's hypothesis and the four-factor model of Morawitz.

It is postulated that ADP secreted by platelets is the physiological thromboplastin which initiates the conversion of prothrombin to thrombin and hence brings about the coagulation of the blood. The experiments which led to the formulation of the hypothesis are described. Experimental work compatible with the hypothesis is outlined. The implications of the hypothesis with regard to the modern cascade theory of coagulation are discussed.

Time perception: effects of introversion/extraversion and task interest.

32 extraverted and 32 introverted college students rated the interest value and estimated the duration of 3-min. intervals filled with reading. There were 3 dull and 3 interesting readings. It was hypothesized that time perceptions of extraverts and introverts would differ when their interest in the task was dissimilar. But no personality differences in time perception and few in interest were found; both extraverts and introverts judged the intervals to be shorter when the reading was interesting.
