Hypocrites or maligned cooperative participants? Experimenter induced normative conflict in zero-sum situations

The failure to recognize the influence of two distinct forms of moral norms can lead to the misattribution of moral behavior to egoistic motives. This is illustrated in the research of Batson and his colleagues (e.g., Batson, Kobrynowicz, Dinnerstein, Kampf, & Wilson, 1997). They reported the appearance of moral failure and hypocrisy motivation in several experiments employing essentially the same “zero-sum” experimental situation. They cited as evidence the discrepancy between participants’ apparently self-serving private acts and their subsequent public ratings of the morality of what they had done as well as their recognition of the “most” moral way to behave. The research reported here supported an alternative explanation that located the experimenter’s implicit and explicit instructions as the source of the discrepancy between the participants’ private acts and their public ratings. The findings confirmed the hypothesis that Batson and his colleagues had not merely made moral norms “salient”. They had actually presented their participants with contradictory “demands”: explicitly inviting them to meet the norm of justified self-interest in private but then give public lip-service to the experimenter’s instructions as to a supererogatory way to behave. When either of the demands was removed, the “hypocrisy” no longer occurred.     

Mood as information in making attributions to discrimination

Previous research demonstrates that people use their mood as information when making a variety of judgments. The present research examines the extent to which people use their current mood as information when making attributions to discrimination. Women were given a positive or negative mood induction and either provided with an external attribution for their current mood state or not. They then reported on discrimination occurring to themselves and other women. When an external attribution for induced mood was not provided, women in positive moods were less likely to report discrimination across three measures than were women in negative moods. When an external attribution was provided, mood had no effect. Implications for understanding the effects of context and individual differences in the perception and reporting of experiences with discrimination are discussed.     

Decoding the Binary: Reconsidering the Hacker Subculture through a Gendered Lens

ABSTRACT

Research has demonstrated that hacker subculture – like many other tech-oriented communities – is disproportionately composed of men. While prior attempts have been made to explain this disparity, few, if any, explore the role of subculture in this gendered divide. Drawing from feminist theories, subcultural theory, and cultural criminology, this theoretical analysis examines the intersection of gender, social structure, hegemony, situated action, and subculture to argue that hacker subculture is (1) male-dominated and androcentric, (2) mired in language, like meritocratic rhetoric, which masks inequity, and (3) conducive to forms of sexual harassment and gendered exclusion. Implications for hacking research and subcultural theory are discussed throughout.     

A table for the rapid determination of the tetrachoric correlation coefficient

A table is developed and presented to facilitate the computation of the PearsonQ ₃ (cosine method) estimate of the tetrachoric correlation coefficient. Data are presented concerning the accuracy ofQ ₃ as an estimate of the tetrachoric correlation coefficient, and it is compared with the results obtainable from the Chesire, Saffir, and Thurstone tables for the same four-fold frequency tables.The authors are indebted to Mr. John Scott, Chief of the Test Development Section of the U.S. Civil Service Commission, for his encouragement and to Miss Elaine Ambrifi and Mrs. Elaine Nixon for the large amount of computational work involved in this paper.     

Septal driving of the hippocampal theta rhythm produces a long-term, proactive and non-associative increase in resistance to extinction

Previous experiments employing electrical or pharmacological induction, or instrumental reinforcement, of hippocampal theta rhythm in rats have reported subsequent performance changes in a number of learning situations. In all these studies theta induction took place either concurrent with or following the behaviour under investigation. In the present two experiments, a treatment phase of electrically-induced hippocampal theta (by septal stimulation at 7·7 Hz) preceded acquisition of a discrete trial, barpress response on a fixed ratio 5 reinforcement schedule. In one of three treatment conditions animals received electrical stimulation (1) on its own, or (2) in a classical conditioning relationship with food delivery as unconditioned stimulus, or (3) temporally uncorrelated with food delivery; controls were implanted with electrodes but not stimulated. After 15 days' acquisition of barpressing, all animals were extinguished over the subsequent 12 days. Results indicated that theta-driving stimulation, independent of any association with food, resulted in increased resistance to extinction of barpressing. In addition, conditions (1) and (3) enhanced the speed of response during early acquisition. These findings cast doubt on a “memory consolidation” hypothesis of hippocampal theta function and demonstrate a non-associative, long-lasting, proactive effect of theta induction on behaviour.
