There's a certain slant of light: Three attitudes toward the political turn in analytic philosophy

There has been a growing interest within analytic philosophy in addressing political and social issues, which has been referred to as the “political turn” in the discipline. The aim of this paper is twofold. First, it discusses the very characterization of the political turn. In particular, it introduces the definition proposed by Bordonaba-Plou, Fernández-Castro, and Torices, suggests that we should not consider the turn a form of activism, and explores an additional benefit of the ideal/nonideal distinction for characterizing the turn. Second, it addresses the concern of what attitude we should take in the face of the different sensitivities we might have with respect to what constitutes an injustice. Which philosophical works should count as part of the political turn? The paper explores three different attitudes toward this dilemma, and favors what it calls the revisionist attitude, which emphasizes the fact that our perception of injustice is subject to error.     

Automatic imitation and spatial compatibility in a key-pressing task

Automatic imitation has been often confounded with spatial compatibility effects. Heyes (2011) called attention to this confound, and proposed some criteria which must be satisfied before these effects could be unequivocally taken to be an index of the functioning of the human mirror system. Evidence satisfying such criteria has been reported by Catmur and Heyes (2011), using a relatively unfamiliar finger abduction movement. However, because many previous studies relied on more familiar actions, we aimed at testing whether analogous effects could be obtained with a more practiced key-pressing task. In Experiment 1, we used anatomical controls (i.e., views of right vs. left hands) under conditions affording mirror imitation, and showed that spatial compatibility masked the effects of automatic imitation. Experiment 2 used rotated conditions to control for this spatial-anatomical confound, and it showed unequivocal effects of automatic imitation, which were obtained regardless of its relation to the spatial stimulus-response mapping. These results cast some doubts on the interpretation of previous reports relying exclusively on scenes presented from a mirror perspective, and suggest the convenience of using both rotated scenes and anatomical controls in order to assess automatic imitation.     

Representational pseudoneglect in line bisection

"Representational pseudoneglect" refers to a bias toward the left side of space that occurs when visual information is remembered. Recently a number of demonstrations of such representational pseudoneglect have appeared. In the present article, we report an experiment in which we adopted the classic line bisection paradigm to study representational pseudoneglect. Participants bisected horizontal lines that were shown in extrapersonal space. When the lines were visible on the screen, there was no evidence of any leftward bias. However, when lines were bisected from memory, the participants demonstrated a clear bias to the left. This is the first demonstration of a leftward bias in the bisection of remembered visually presented lines.     

Predictability and heritability of individual differences in fear learning

Our objective was to characterize individual differences in fear conditioning and extinction in an outbred rat strain, to test behavioral predictors of these individual differences, and to assess their heritability. We fear-conditioned 100 Long-Evans rats, attempted to extinguish fear the next day, and tested extinction recall on the third day. The distribution of freezing scores after fear conditioning was skewed, with most rats showing substantial freezing; after fear extinction, the distribution was bimodal with most rats showing minimal freezing, but a substantial portion showing maximal freezing. Longer rearing episodes measured prior to conditioning predicted less freezing at the beginning of extinction, but differences in extinction learning were not predicted by any baseline exploratory behaviors. We tested the heritability of extinction differences by breeding rats from the top and bottom 20 % of freezing scores during extinction recall. We then ran the offspring through the same conditioning/extinction procedure, with the addition of recording ultrasonic vocalizations throughout training and testing. Only a minority of rats emitted distress vocalizations during fear acquisition, but the incidence was less frequent in the offspring of good extinguishers than in poor extinguishers or randomly bred controls. The occurrence of distress vocalizations during acquisition predicted higher levels of freezing during fear recall regardless of breeding line, but the relationship between vocalization and freezing was no longer evident following extinction training, at which point freezing levels were influenced only by breeding and not by vocalization. The heritability (h ²) of extinction recall was estimated at 0.36, consistent with human estimates.     

The emotional cost of charitable donations

Donations in support of a charitable cause can create a conflict between moral intuitions (e.g., fulfilling moral obligations and helping as many individuals in need as possible) and the cost entailed by following one's moral intuitions (e.g., spending money). The present paper investigates this conflict by putting people in a situation in which they must choose whether to help three women by giving more money or help one woman by giving less. In addition, the paper uses the attraction effect paradigm to counteract the single victim effect and reduce the conflict. Experiment 1 demonstrates that in a two-alternative context the majority of participants choose to help one woman by giving €150 instead of helping three women by giving €450. Experiment 2 replicates this finding and highlights the role of emotion regulation strategies in the management of the emotional conflict arising in the two-alternative condition. In both studies, the introduction of a third, dominated alternative reduces the conflict and makes it easier to choose the programme asking for a higher donation and helping three women. Implications for charitable donations and the role of the conflict between moral intuitions and economic costs are discussed.
