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.     

Mood and alcohol consumption: an experience sampling test of the self-medication hypothesis

In this investigation the authors applied the experience sampling method to prospectively test the self-medication hypothesis. In vivo reports gathered in the context of daily life demonstrated that nervousness was the only negative mood state to predict increases in alcohol consumption later in the course of the day. Further examination of this within-person relationship demonstrated that men were more likely to consume alcohol when nervous than were women, but this association was unrelated to family history of alcoholism, problem drinking patterns, or trait anxiety and depression. Consistent with the self-medication hypothesis, cross-sectional analyses also confirmed that alcohol consumption was generally associated with lower levels of nervousness; this effect varied by several demographic and clinical variables. These findings are discussed in terms of the diversity of reasons for alcohol consumption and their potential for explaining problem drinking.     

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.     

In Search of the Self: A Positron Emission Tomography Study

Abstract—Previous work using positron emission tomography (PET) has shown that memory encoding processes are associated with preferential activation of left frontal regions of the brain, whereas retrieval processes are associated predominantly with right frontal activations. One possible reason for the asymmetry is that episodic retrieval necessarily involves reference to the self, and the self-concept may be represented (at least partially) in right frontal regions. Accordingly, the present study investigated the possibility that encoding of self-related material might also activate right frontal areas. Eight right-handed volunteers judged trait adjectives under four separate PET scan conditions: (a) relevance to self, (b) relevance to a well-known public figure, (c) social desirability, and (d) number of syllables. The results showed that self-related encoding yielded left frontal activations similar to those associated with other types of semantic encoding, but also specific activations in the right frontal lobe. It is concluded that the concept of self involves both general schematic structures and further specific components involved in episodic memory retrieval.     

Gender Advertisements in Magazines Aimed at African Americans: A Comparison to Their Occurrence in Magazines Aimed at Caucasians

Advertisements from magazines aimed at AfricanAmericans were compared to ads from magazines aimedpredominantly at Whites. Over 200 magazineadvertisements were analyzed according to Goffman's(1976) rubrics of licensed withdrawal, function ranking,relative size, ritualization of subordination, femininetouch, and the family. Results indicated that the adsfrom White-oriented magazines were characterized by relatively frequent displays of licensedwithdrawal and ritualization of subordination. Thoseaimed at African Americans, however, were characterizedby more frequent portrayals of the family. Almost half of each sample were classified into another category which followed none ofGoffman's rubrics. Results are discussed in terms of thedemand characteristics implicit in gender advertisements and in terms of cultural differences in genderrole expectations.

Through rose-tinted glasses: How inducing and resolving curiosity makes consumers less skeptical and improves their product evaluations

Research indicates that in general, curiosity leads to more intense processing of an advertisement, which might result in a more skeptical response toward a persuasive message. However, we propose the opposite and argue that a process of evoking curiosity toward a stimulus in the first step (with the creation of an information gap) and resolving it in the second step creates a positive affective experience. Upon receiving curiosity-resolving information after becoming curious, consumers are less skeptical toward the advertised product, which leads to a more favorable attitude and a higher purchase intention. Based on four studies, we demonstrate curiosity's skepticism-reducing effect, its downstream consequences, and the underlying mechanism of positive affect. We show that this curiosity-stimulating way of information disclosure caused the effect instead of the information itself, which remained constant. The effects occur for integral curiosity, directed at the focal product, and for incidental curiosity, elicited by an unrelated stimulus. These results contribute to understanding consumer responses to curiosity-evoking advertisements, which are widespread, and provide implications for consumer psychologists, practitioners, and policy makers.     

The Personal Acquaintance Measure: a tool for appraising one's acquaintance with any person

The authors developed and evaluated the psychometric properties of the 18-item Personal Acquaintance Measure (PAM) and investigated how the PAM relates to self- other agreement in personality ratings. Results support that 6 factors represent the PAM (Duration, Frequency of Interaction, Knowledge of Goals, Physical Intimacy, Self-Disclosure, Social Network Familiarity), which showed evidence of internal consistency, test-retest reliability over 3 weeks, sensitivity to known group differences, discriminant validity from socially desirable responding, and convergent validity with other relationship inventories. Results also show that the PAM positively predicted self-other agreement. The authors discuss the implications of these findings for the PAM and research in person perception, although this measure may also be used in other research areas.
