Target detection in one visual field in the presence or absence of stimuli in the contralateral field by right- and left-handed subjects

Marked differences in detectability are observed as a function of retinal locus when subjects are required to find a briefly exposed target pattern of uncertain location in the presence of a number of discriminably different nontarget patterns. Our previous studies using this search paradigm have attributed these detectability differences, and the right visual field detectability superiority associated with them, to a serial (scanning) mechanism which tends to examine stimuli in the right field earlier than those in the left. The present experiment, performed on large groups of right- and left-handed subjects, was designed to test the hypothesis that there are two independent serial processors, one in each hemisphere--an hypothesis which might account for the differences in detectability within and between the two half-fields in terms of hemispheric processing differences. The results are inconsistent with the dual independent serial processor hypothesis but are fully consistent with a single serial processor, a scanning mechanism, which has access to the information presented to both visual half-fields.     

From is to ought: Natural Law in Buddhadasa Bhikkhu and Phra Prayudh Payutto

The contemporary Thai Theravada Buddhist monks Buddhadasa Bhikkhu and Phra Prayyudh Payutto espouse a version of natural law thinking in which the norms of good behavior derive from the nature of the world, specifically its features of conditionality, causality, karma and interdependence. An ethic which stresses non-egoic harmony is the result. This paper (1) develops the notion of natural law in their thinking and (2) critically evaluates these ideas as a foundation for ethical thought, specifically asking whether such ideas recognize something of value in the individual per se and in individual freedom and, in an interdependent world, how one can challenge injustice or a brutal government.
