Face perception is a highly conserved process that directs our attention from infancy and is supported by specialized neural circuitry. Oxytocin can increase accuracy and detection of emotional faces, but these effects are mediated by valence, individual differences, and context. We investigated the temporal dynamics of oxytocin’s influence on the neural substrates of face perception using event related potentials (ERP). In a double blind, placebo controlled within-subject design, 21 healthy male adults inhaled oxytocin or placebo and underwent ERP imaging during (...) two face processing tasks. Experiment 1 investigated effects of oxytocin on neural correlates of fearful versus neutral facial expressions, and Experiment 2 manipulated point-of-gaze to neutral faces. In Experiment 1, we found that oxytocin reduced N170 latency to fearful faces. In Experiment 2, N170 latency was decreased when participant gaze was directed to the eyes of neutral faces; however, there were no oxytocin-associated effects in response to different facial features. Findings suggest oxytocin modulates early stages of social perception for socially complex information such as emotional faces relative to neutral. These results are consistent with models suggesting oxytocin impacts the salience of socially informative cues during processing, which leads to downstream effects in behavior. Future work should examine how oxytocin affects neural processes underlying basic components of social behavior (such as, face perception) while varying emotional expression of stimuli or comparing different characteristics of participants (e.g., gender, personality traits).

This paper considers critical rationalism under an institutional perspective. It argues that a methodology must be incentive compatible in order to prevail in scientific competition. As shown by a formal game-theoretic model of scientific competition, incentive compatibility requires quality standards that are hereditary: using high-quality research as an input must increase a researcher’s chances to produce high-quality output. Critical rationalism is incentive compatible because of the way it deals with the Duhem-Quine problem. An example from experimental economics illustrates the relevance (...) of the arguments.

Radical Millianism agrees with less radical varieties in claiming that ordinary proper names lack “descriptive senses” and that the semantic content of such a name is just its referent but differs from less radical varieties of Millianism in claiming that any pair of sentences differing only in the exchange of coreferential names cannot differ in truth‐value. This is what makes Radical Millianism radical. The view is surprisingly popular these days, and it is popular despite the fact that, until very recently, (...) there was not a single argument for it. Theodore Sider and David Braun (2006) have tried to provide the missing argument, but, I argue, their attempt fails. I conclude that we (still) have no reason to be Radical Millians. (shrink)

We present a relative consistency proof for second order systemRRC* and for certain important extensions of this system. The proof proceeds as follows: we prove first the equiconsistency of the strongest of such extensions (viz., systemH RRC*+(/CP**)) with second order systemT * . Now, N. Cocchiarella has shown thatT * is relatively consistent to systemT*+Ext; clearly, it follows thatH RRC*+(/CP**) is relatively consistent toT*+E xt. As an immediate consequence, the relative consistency ofRRC* and the other extensions also follows, being all (...) of them subsystems ofH RRC*+(/CP**). (shrink)

It is universally agreed that in the “Gray’s Elegy Argument” (GEA) Russell raises a difficulty for the attempt to “speak about” meanings (the phrase is Russell’s) and that the difficulty, assuming it to be genuine, shows the very notion of meaning to be unintelligible. In this paper I try to show that in the GEA Russell considers and rejects an alternative way of manifesting an understanding of meanings—namely, by “dealing with” them (also Russell’s phrase). This step in the GEA has (...) not, so far as I am aware, been noticed before. (shrink)
