CAN PERSONALITY UNDERPIN ATTITUDES TO BOTH SCIENCE AND RELIGION?

Drawing on Peter Harrison's argument that individuals should be attributed a central role in analyses of the relationship between science and religion, this article proposes that an understanding of personality can help us better appreciate a person's attitudes to both science and religion. Rather than seeing an individual's attitudes to these two topics as separate, if sometimes overlapping, parts of their lives, it is suggested that both may result from psychological drives and sometimes from the same psychological drive. Two contrasting case studies are employed to illustrate this proposal. First, Paul Dirac who, it is argued, was on the autistic spectrum, a personality profile that is often linked to both mathematical physics and atheism. By contrast, Michael Faraday's scientific practice and his commitment to a specific form of Christianity were underpinned by his need for security, as assured by the God‐given laws that operated in both the physical and moral domains.     

Effect of timing of information about mitigating circumstances on emotional responses to provocation and retaliatory behavior

To determine whether the reduction of retaliatory behavior by knowledge of mitigating circumstances is due to less motivation to retaliate or to an inhibition of motivated retaliation, subjects were provoked by a rude experimenter and informed of mitigating conditions (a) before provocation, (b) after provocation, or (c) not at all. Physiological data revealed that prior knowledge of mitigation prevented pronounced excitatory responses to prococation. In contrast, when mitigating conditions were not known, excitatory responses to provocation were intense. In addition, when mitigating information was supplied after provocation, excitatory responses decayed more rapidly than when no such information was supplied. Retaliatory behavior, as measured in complaints about the rude experimenter, was substantially lower in the condition in which mitigation preceded provocation than in the other two conditions. The retaliatory behavior of subjects who were informed of mitigation after being provoked did not differ significantly from that of subjects who were not informed of mitigation. The findings were interpreted as incompatible with the assumption that under mitigating conditions retaliation is motivated but inhibited and as generally supportive of the proposal that mitigation attenuates the response to provocation. In order to explain the failure of the reception of mitigating information after provocation to reduce retaliatory behavior in spite of the observed facilitation of excitatory decay, it was suggested that when subjects were experiencing high levels of anger, they formed a behavioral disposition to retaliate, which outlasted the state of elevated arousal.     

Simultaneous time and size perception

Judgments of the apparent duration and size of visually presented circles vary directly with the duration and size of the presented stimuli. When the frequencies of stimulus duration (short vs. long) and stimulus area (small vs. large) are varied, perceived size and duration are directly related to the frequency of the lower attribute value (short or small). These data are compared to the predictions of different information-processing models. The model which accounts for the data best is one in which it is assumed that perceived size and perceived duration grow together over the course of time spent sampling size information, and that attribute frequency affects the rate of sampling and/or the point at which sampling stops.
