The time taken to react voluntarily to a stimulus is far longer than can be accounted for by ordinary processes of nerve conduction and synaptic delay, and varies unpredictably from trial to trial. Though random, the distribution of reaction times usually follows a relatively simple law, which in turn can be explained by the LATER model, in which a decision signal, representing belief in the existence of the target, rises in response to incoming sensory evidence from an initial value to (...) a criterion level at which action is initiated. But the rate of rise fluctuates randomly from trial, to an extent that cannot be explained by sensory noise at the input. These conclusions, confirmed by recording from neurons in the frontal eye fields, suggest that the randomness of reaction time is due to a deliberate, gratuitous, neural process which confers certain biological advantages as well as having implications for general ideas about the nature of ‘free will'.

Within the broader agenda of adherence research, health beliefs have been identified as being significant predictors of adherence. Specifically, perceived threat as a health belief has received considerable attention in compliance and adherence research from multiple perspectives in multiple patient populations. The purpose of this paper is to analyze the concept of perceived threat as it relates to treatment adherence through a series of perspectives: conceptual, methodological, and empirical. Analysis of the literature reveals that there is lack of consistency in (...) operationalization of perceived threat as it relates to treatment adherence. Perceived threat is most commonly cited in studies that focus on health beliefs or utilize a stress and coping paradigm. Instruments have been developed with items that measure perceived threat. Measures of threat occur primarily through uni‐dimensional measures that do not reflect the inter‐relatedness of the threat experience to personal and contextual factors. Future research examining perceived threat from a cognitive appraisal perspective, where both primary and secondary appraisals can be examined, may provide additional insight into factors affecting treatment adherence.

Excerpt from The Esthetic Basis of Greek Art of the Fifth and Fourth Centuries B. C The bibliography of my subject is very nearly negligible. One debt (outside of Greek archaeology altogether) is, however, a heavy one; and I wish to acknowledge great obligation to the keen and serious dialectic which distinguishes Geoffrey Scott's of Humanism.
