The Preconditions and Consequences of Relative Deprivation: Two Field Studies1

Two field studies assessed the preconditions and behavioral consequences of relative deprivation. A sample of single mothers receiving government assistance participated in Study 1, and a sample of working women participated in Study 2. We found general support for a 2-factor model of the preconditions of relative deprivation, in which wanting the desired state and deserving the desired state were the best predictors of discontent. In both studies, discontent regarding the status of one's group (i.e., single mothers or working women) was specifically predictive of reports of group-directed protest behaviors. In Study 2, discontent regarding one's own status was specifically predictive of willingness to engage in self-improvement behaviors. Participants in both studies reported more group discontent than personal discontent. These findings provide support from naturalistic settings for the construct of relative deprivation.     

Cue-elicited negative affect in impulsive smokers.

Impulsivity is associated with cigarette smoking, but the nature of this relationship and the mechanisms that maintain it are relatively unknown. The relationship has often been thought to reflect appetitive processes, but research suggests that an affective pathway exists as well. The present study tested the effect of impulsivity on affective responses to an environmental smoking cue. Adult smokers (N=62) were exposed to a neutral cue and a smoking cue in separate experimental sessions in a repeated-measures design. Mixed-effects regression analyses showed that larger postexposure increases in negative affect were associated with high scores on 2 facets of impulsivity: urgency, t(179)=6.16, p<.001, and sensation seeking, t(179)=4.75, p<.001. Heightened impulsivity was associated with lower levels of positive affect generally but not with positive affective responses to cue exposure. Findings provide support for the existence of a negative affective pathway linking impulsivity and cigarette smoking, and they suggest that this pathway may be specific to the urgency and sensation-seeking components of impulsivity.     

Grounding the Luck Objection

Many object to libertarianism by arguing that it manages to solve one problem of luck (the threat of determinism) only by falling prey to another (the threat from indeterminism). According to this objection, there is something freedom-undermining about the very circumstances that the libertarian thinks are required for freedom. However, it has proved difficult to articulate precisely what it is about these circumstances that is supposed to undermine freedom—the absence of certain sorts of explanations has perhaps been the most common complaint. In this paper, however, I argue that recent work on the metaphysics of ontological dependence provides the resources for formulating the luck objection in its strongest form.     

Food-related stimuli increase desire to eat in hungry and satiated human subjects

In the present study, the effect of food-related cues on the desire to eat chocolate in hungry and satiated subjects was investigated. Subjects (n=46) were randomly assigned to either a hungry or satiated group and then assigned to a group receiving one of the following stimuli: taste (2 M&Ms), sight (a photograph of M&Ms), cognition (a passage describin M&Ms), or control (no stimulus). In each testing session, subjects rated their desire to eat chocolate before and after the 90-s presentation of the particular stimulus. Each subject was then given a half pound of M&Ms so that actual consumption could also be measured. Results indicated that, following the presentation of the sight and taste stimuli, the subjects’ desire to eat chocolate was significantly increased. Furthermore, no differences in chocolate consumption due to state of hunger or type of food-related stimulus presented were found.     

Science Anxiety as a Function of Gender and Experience

This study examined the influence of gender and various background factors on science anxiety. Students (50 women, 37 men) took the Science Anxiety Scale (Mallow, 1994), provided information about high school and college academic accomplishments, described gender-role stereotyping in the home, and evaluated their science teachers and science experiences. Most participants were Caucasian and from an upper-middle class background. Women were not uniformly more science anxious and had a relatively similar science background to men, although they had higher science grades in high school and did report less stringent sex-role socialization in the home. However, students with high science anxiety took fewer science courses in college, had lower SAT-Q scores, and reported that their high school science teachers were not helpful. The findings regarding gender- and anxiety-linked differences are discussed in terms of women's and men's differential interpretations of their abilities, the influence of parental gender typing on pursuit of science, and the gender-appropriateness of studying science.     

Distinguishing Serial and Parallel Parsing

This paper discusses ways of determining whether the human parser is serial maintaining at most, one structural interpretation at each parse state, or whether it is parallel, maintaining more than one structural interpretation in at least some circumstances. We make four points. The first two counterclaims made by Lewis (2000): (1) that the availability of alternative structures should not vary as a function of the disambiguating material in some ranked parallel models; and (2) that parallel models predict a slow down during the ambiguous region for more syntactically ambiguous structures. Our other points concern potential methods for seeking experimental evidence relevant to the serial/parallel question. We discuss effects of the plausibility of a secondary structure in the ambiguous region (Pearlmutter & Mendelsohn, 1999) and suggest examining the distribution of reaction times in the disambiguating region.     

Instructional cues modify performance on the Iowa Gambling Task

The current study investigated whether acute alcohol intoxication produces impaired decision-making on tasks assessing ventromedial prefrontal (VMF) cortex functioning and impulsive responding. Participants completed the Iowa Gambling Task (IGT), a decision-making test targeting the VMF, and the Newman Perseveration Task (NT), a measure of impulsivity. Personality measures of impulsivity were assessed using the Barratt Impulsiveness Scale (BIS). To encourage natural responding on both tasks, participants were falsely informed that the study was examining the effects of alcohol on memory; the impulsivity tasks were presented as 'distractor' tasks. Advantageous performance on the IGT was related to specific instructional cues as well as to knowledge about the experimental purpose. Performance of intoxicated and sober participants did not differ. A subsequent study in which the true purpose of the experiment was revealed confirmed that alcohol does not affect IGT performance. Most importantly, the instruction-sensitivity of the IGT emphasizes the importance of salient cues for decision-making.
