A perceptual phenomenon and its neurophysiological correlate.

A square-wave grating from which the fundamental harmonic has been subtracted (missing fundamental grating) when viewed from a suitable distance appears similar to another grating of periodicity three times higher. The neurons of the visual cortex of the cat, in a given range of spatial frequencies characteristic of each cell, give similar responses to the two gratings.     

GENDER DIFFERENCES IN REASONING ABOUT MILITARY INTERVENTION

The question of gender associations with moral reasoning and values has received a great deal of attention since Gilligan first published In a Different Voice in 1982. Various authors have argued that women are less hierarchical, more relational, more caring, more empathetic, and more concerned about not harming others than men. Yet, these claims have been questioned by other scholars. Data from a small survey of college students are used to address this question. We found that, in examining students' narrative justifications of their opinion on a particular question of military intervention, gender was related to the type of justification used in a manner consistent with the arguments of Gilligan. We argue that "objective" tests are less likely to detect this difference than content analyses of narratives. The different bases of judgments have implications for political opinions as well as interpersonal interactions.
