Mouse killing in rats induced by lesions of the medial hypothalamus or medial accumbens: short-term preoperative exposure to a mouse does not suppress the killing

Rats were either exposed or not exposed to a mouse in their living cage for a 48-hr period. At the end of this time a bilateral lesion was made in the medial accumbens region or in the medial hypothalamus. When tested 2 days postoperatively, the killing frequency among rats that had been exposed to mice preoperatively was not significantly lower than that of rats that were not preoperatively exposed. The ineffectiveness of preoperative experience in suppressing the mouse killing induced by medial accumbens and medial hypothalamic lesions is similar to that found previously with dorsal-median raphe lesions and olfactory bulb lesions and is in contrast to the ease with which preoperative experience prevents mouse killing induced by septal lesions and serotonergic lesions induced by 5,7-dihydroxytryptamine.     

Sex differences and the effect of instruction on reorientation abilities by humans

This study examined whether differences in the amount of information provided to men and women, in the form of verbal instruction, influenced their encoding during a reorientation task. When a navigator needs to orient, featural (e.g., colour or texture) and geometry (e.g., metric information) are used to determine which direction to begin traveling. The current study used a spatial reorientation task to examine how men and women use featural and geometric cues and whether the content of the task’s instructions influenced how these cues were used. Participants were trained to find a target location in a rectangular room with distinctive objects situated at each corner. Once the participants were accurately locating the target, various tests manipulating the spatial information were conducted. We found both men and women encoded the featural cues, and even though the features provided reliable information, participants generally showed an encoding of geometry. However, when participants were not provided with any information about the spatial aspects of the task in the instructions, they failed to encode geometry. We also found that women used distant featural cues as landmarks when the featural cue closest to the target was removed, whereas men did not. Yet, when the two types of cues were placed in conflict, both sexes weighed featural cues more heavily than geometric cues. The content of the task instructions also influenced how cues were relied upon in this conflict situation. Our results have important implications for our understanding of how spatial cues are used for reorientation.     

Nietzsche's agon with ressentiment: towards a therapeutic reading of critical transvaluation

This paper examines the therapeutic implications of Nietzsche's critique of ressentiment and revenge as our signature malady. §I examines the obstacles to a therapeutic reading of Nietzsche's thought, including his anti-teleological tendencies and the value he places on sickness. Then there is the energetic problem of finding resources to tackle ressentiment, given the volitional exhaustion of modern nihilism. Finally, the self-referential implications of Nietzsche's critique of slave values threaten to trap his thought in a futile ressentiment against ressentiment. If the impulse to cure or redeem us from revenge through critical destruction repeats the logic of revenge, then the challenge for a therapeutic reading is to think through the transformation of revenge on the basis of repetition.An agonal reading of Nietzsche's philosophical practice is proposed to tackle these problems in §II.In Homer's Contest (1872), Nietzsche describes the transference (Übertragung) of Hesiod's evil Eris – goddess of war and destruction – into the good Eris of the contest or agon: destructive impulses are affirmed as stimulants, but also transformed into culture-building forces through an agonal regime of limited aggression. By superimposing this regime, as a model for Nietzsche's textual confrontations, on their unconscious text of embodied ressentiment, a therapeutic perspective emerges, based on three principles: affirmation; mutual empowerment; and externalisation. The agon performs an affirmative transformation of revenge on the basis of a fertile repetition: destructive affects (as in ressentiment) are transferred into constructive deeds of mutual antagonism. Through Nietzsche's agonal discourse, a reactive regime of internalised aggression is externalised in active deeds of limited philosophical aggression – a therapeutic transformation of (self-)destructive into constructive, philosophical impulses.     

Judgment Difficulty and the Moral Intensity of Unethical Acts: A Cognitive Response Analysis of Dual Process Ethical Judgment Formation

This study analyzes cognitive responses to explore a dual processing perspective of ethical judgment formation. Specifically, the study investigates how two factors, judgment task difficulty and moral intensity, influence the extent of deontological and teleological processing and their effects on ethical judgments. A single experiment on 110 undergraduate research participants found that judgment task difficulty affected the extent of deontological and teleological processing. Although moral intensity affected ethical judgments, it did not produce effects on either deontological or teleological cognitive responses. Results did not support the hypotheses that deontological and teleological cognitive responses would mediate the relationships between the experimental factors and ethical judgments. Overall, the results support continued research of factors that affect the nature of information processing in ethical decision situations and the use of cognitive response analysis as a tool for conducting this research.
