The Effect of Generalized Compliments,Sex of Server,and Size of Dining Party on Tipping Behavior in Restaurants1

This study examined the effects of food servers' sex, the use of generalized compliments, and the size of the dining party on tipping behavior in restaurants. Four food servers (2 males, 2 females) waited on 360 parties eating dinner, and either complimented or did not compliment the parties on their dinner selections. Results indicated that food servers received significantly higher tips when complimenting their parties than when not complimenting them, although as the size of the party increased, the effectiveness of compliments decreased. These results and their implications are discussed.     

A longitudinal study of student-teacher relationship quality, difficult temperament, and risky behavior from childhood to early adolescence

This study examines the mediating role of student-teacher relationship quality (conflict and closeness) in grades 4, 5, and 6 on the relation between background characteristics, difficult temperament at age 4½ and risky behavior in 6th grade. The longitudinal sample of participants (N = 1156) was from the NICHD Study of Early Child Care and Youth Development. Structural equation modeling was used to estimate paths from (a) background characteristics to student-teacher relationship quality and risky behavior, (b) temperament to student-teacher relationship quality and risky behavior, and (c) student-teacher relationship quality to risky behavior. Findings indicate that students' family income, gender, receipt of special services, and more difficult temperament were associated with risky behavior. In addition, student-teacher conflict was a mediator. Students with more difficult temperaments were more likely to report risky behavior and to have conflict in their relationships with teachers. More conflict predicted more risky behavior. Closer student-teacher relationships were associated with less risky behavior. Results suggest negative relationships, specifically student-teacher relationships, may increase the risk that certain adolescents will engage in risky behavior.     

The Validity and Structure of Culture‐Level Personality Scores: Data From Ratings of Young Adolescents

ABSTRACT We examined properties of culture‐level personality traits in ratings of targets (N=5,109) ages 12 to 17 in 24 cultures. Aggregate scores were generalizable across gender, age, and relationship groups and showed convergence with culture‐level scores from previous studies of self‐reports and observer ratings of adults, but they were unrelated to national character stereotypes. Trait profiles also showed cross‐study agreement within most cultures, 8 of which had not previously been studied. Multidimensional scaling showed that Western and non‐Western cultures clustered along a dimension related to Extraversion. A culture‐level factor analysis replicated earlier findings of a broad Extraversion factor but generally resembled the factor structure found in individuals. Continued analysis of aggregate personality scores is warranted.     

The influence of gender,social roles,and facial appearance on perceived emotionality

One of the most pervasive gender stereotypes in Western culture concerns expectations regarding men's and women's emotionality. Whereas men are expected to be anger prone, women are expected to smile more. At the same time, men are generally perceived as more facially dominant and facially dominant individuals are expected to show more anger. That is, both facial appearance and social role expectations would lead observers to expect men to show more anger. The present research had the goal to disentangle the unique contribution of these two factors. As it is impossible in our society to fully untangle the influence of these factors since they are highly confounded, we created an alien society where these factors could be unconfounded. In this alien world, Deluvia, child rearing is exclusively assumed by a third gender, the caregiver, whereas men and women share the same social roles. The facial appearance of the Deluvians was varied along the dominance continuum. The results showed that facially dominant Deluvians, regardless of gender, were expected to show more anger, disgust, and contempt and less happiness, fear, sadness, and surprise. Also, the nurturing caregivers were expected to show less anger, contempt, and disgust as well as more fear, sadness, and surprise, regardless of facial appearance. No effect of gender per se on perceived emotionality was found. Copyright © 2009 John Wiley & Sons, Ltd.     

Consequence of Self Versus Externally Generated Visual Motion on Postural Regulation

A limiting factor in the use of virtual environments to examine perception and action is that it is dependent on the quality of the interaction. A virtual reality game (first-person viewpoint with moderate difficulty) was used to investigate the link between control and postural regulation. Postural regulation was examined using a motion capture system, and the differences that emerged as a result of the participant being a passive observer versus an active participant were evaluated using a fractal procedure: dispersion analysis. A significant interaction was found between control and health, namely, participants' postural behavior tended to be less uniform when they were sick and when they were in control of the environment. These results lead the authors to suggest that successful interaction with novel environments depends on the ability to find and consistently use appropriate control strategies.
