Restaurant Tipping: Free‐Riding,Social Acceptance,and Gender Differences1

The practice of paying gratuities for services is a worldwide custom. Tipping is found only in some professions, which suggests that it serves to increase the efficiency of specific kinds of exchanges. The literature accepts the view that monitoring of employees by customers appears to be the logical rationale for the practice of tipping. This can be seen in that gratuities are paid at the discretion of consumers after they receive the services for which they are paying. However, it does not explain why, given the voluntary aspect of tipping, rational people would not free‐ride on the tipping of others. We found that both men and women free‐ride in their tipping behavior. Yet, we also found that men are more influenced by social acceptance or approval in their tipping behavior than are women.     

The importance of social structure and social interaction in stereotype consensus and content: is the whole greater than the sum of its parts?

This paper addresses the hypothesis derived from self‐categorization theory (SCT) that the relationship between groups and stereotyping will be affected by the social structural conditions within which group interaction occurs. A mixed design experiment (n=56) measured low‐status groups' stereotypes and preferences for conflict with a high‐status outgroup prior to and after within‐group discussion across varying social structural conditions. Over time, participants in [open] conditions consensualized around positive conceptions of the outgroup and endorsed acceptance of their own [low status] position. However, in [closed] conditions participants consensualized around positive conceptions of the ingroup, negative conceptions of the outgroup, and tended towards preferences for collective protest. It is argued that the data support S‐CT's contention that stereotyping and group processes are fundamentally interlinked and that neither can be properly understood in isolation from the dynamics of the surrounding intergroup context.

Implicit and explicit tests of odor memory reveal different outcomes following interference

Experiencing two odors as a mixture can later increase their perceived similarity when presented separately. Such an increase in similarity can be used as an implicit measure of how well participants remember the mixture. Three experiments tested the resistance to interference of this effect by first giving participants exposure to two 2-odor mixtures and then presenting each odor from one mixture (interfered pair) separately many times. After the latter interference phase, participants rated the similarity of the two odors in each pair. The experiments varied in terms of the number of initial exposures to the mixtures, the number of odor presentations in the interference phase, and the control conditions employed. No difference in similarity ratings for the interfered and non-interfered pair was found in any experiment. In contrast to the lack of interference with this implicit measure, an explicit measure of memory based on participants’ ratings of odor frequency revealed that they could recall to some degree that the interfered odors had been presented alone in the second phase. These results suggest that implicit memory for odor mixtures is highly resistant to interference and is consistent with a configural encoding account of this effect.     

Dehumanizing but competent: The impact of gender,illness type,and emotional expressiveness on patient perceptions of doctors

This study is the first attempt to investigate men's and women's anticipated reactions to a consultation with a doctor holding either a dehumanizing or humanistic approach to patient treatment. Participants (N = 375) read a vignette depicting a doctor's treatment philosophy—emphasizing either the metaphor of the body as a machine (dehumanizing condition) or emphasizing individual humanness (humanizing condition). They then imagined consulting the doctor about a psychological or physical illness. Although, medical dehumanization had undesirable consequences, some men rated the dehumanizing doctor as more competent than the humanizing doctor. These were men who were (a) emotionally expressive and seeking help for a psychological illness, and (b) men low in emotional expressiveness seeking help for a physical illness.     

Race Shapes Perceptions of Juvenile Offenders in Criminal Court1

We investigated the effects of defendant race, victim race, and juror gender on non‐African American mock jurors' perceptions of crimes committed by juvenile offenders. We predicted that mock jurors, particularly men, would render more pro‐prosecution case judgments when the defendant was African American than White. We also predicted that defendants would be judged more harshly when the crime victim was portrayed as White rather than as African American. Although there were few main effects of defendant race or victim race on case judgments, defendant and victim race by juror gender interactions revealed that men (but not women) demonstrated the predicted bias against African American defendants and victims. Explanations and implications are discussed.     

The Role of Police Perceptions and Practices in the Development of “Public Disorder”1,2

Recent studies suggest that crowd conflict needs to be understood as an interaction between the crowd and out‐groups such as the police. This paper describes a questionnaire survey in which 80 police officers from 2 United Kingdom forces were asked about their perceptions of crowds, appropriate “public order” policing methods, and attributions of responsibility for crowd conflict. As predicted, police officers saw the composition of crowds as mixed; yet they also constructed a dichotomy between a powerful minority, capable of exerting influence in the service of disorder, and a majority, who are unable to resist this influence. Police officers did not clearly endorse the view that crowds pose a homogeneous threat. They recommended control and quick intervention to prevent the escalation of crowd violence but denied that such methods might themselves contribute to conflict. Path analysis provides suggestive evidence that these perceptions of the crowd are related as part of a coherent ideology. Overall, these results offer support for the elaborated social identity model of crowd behavior as a dynamic intergroup process.     

Gender Differences in Interest and Knowledge Acquisition: The United States,Taiwan, and Japan

The relationship between interest and knowledge was investigated in a representative sample of 11th grade students from cultures that differ in the strength of their gender-role stereotypes and their endorsement of effort-based versus interest-based learning. Among 11th graders from the United States (N = 1052), Taiwan (N = 1475), and Japan (N = 1119), boys preferred science, math, and sports, whereas girls preferred language arts, music, and art. General information scores were comparable across the three locations; however, boys consistently outscored girls. Gender and interest in science independently predicted general information scores, whereas gender and interest in math independently predicted mathematics scores. Cultural variations in the strength of the relationship between gender, interest, and scores indicate that specific socialization practices can minimize or exaggerate these gender differences.     

Getting technical about awareness

It has recently been argued that post-decision wagering provides an objective measure of awareness. We critically evaluate this claim, emphasizing the distinction between performance without awareness and a reluctance to gamble in full awareness of weak sensory evidence. We address two key methodological issues. The first is the design of the pay-off matrix to reward a strategy of wagering that reflects the strength of sensory evidence. The second is the use of signal detection theory to analyze the resulting data. We argue that proper treatment of these issues is essential if post-decision wagering is to prove valuable in validating claims of perception without awareness in normal subjects and neuropsychological patients.     

How the “Northern Irish” National Identity Is Understood and Used by Young People and Politicians

The conventional understanding of the nation within social psychology is as a category of people or “imagined community.” However, work within the discursive tradition shows that citizens tend to discuss nationhood in a variety of modes, including the use of nonhuman categories such as references to the physical landscape of the country. This article aims to give a more comprehensive overview of how young people understand the Northern Irish identity, a new and potentially inclusive national category in a divided society, and how politicians articulate it in rhetoric. In Study 1, students (N = 286) discussed this identity in 44 peer‐led focus groups. Thematic analysis of their discussions shows four distinct ways in which it is constructed: as a distinctive people, as an identity claim, as a “hot” political project, and as a “cold” or banal indicator of place. In Study 2, Members of the Legislative Assembly at Stormont (N = 49) responded to open‐ended questions about the Northern Irish identity. Each of the parties used different conceptualizations for rhetorical effect. These results give a deeper understanding of the multifaceted nature of national identity and its ability to promote political agendas.     

The role of experience in liking "read-to-drink" alcoholic beverages.

Ready-to-drinks (RTDs) are composed of an alcoholic component and a soft-drink base and are primarily consumed by a youth market. The authors explored whether liking and experience with an RTD soft-drink base predicts liking for the RTD. Participants (N=350) from ages 12 to 30 years sampled 3 RTDs and their respective soft-drink and alcoholic components. For milk- and fruit-based RTDs, liking for and familiarity with their soft-drink base was the best predictor of liking for and familiarity with the RTD itself. For the Coke-based RTD, familiarity with and liking for bourbon best predicted familiarity with and liking for the RTD. All of these effects were consistent across blind and nonblind testing. The authors' results suggest that where there is perceptual similarity between the RTD and its soft-drink base, these beverages may provide an easy transition into alcohol consumption for novice drinkers.
