Effects of Touch on Gratuities Received in Same‐Gender and Cross‐Gender Dyads1

This study examined whether or not a nonreciprocal brief shoulder touch would increase gratuities received by servers. Data from 400 patrons were collected by 4 servers who enacted the touch manipulation while working in 2 separate eating establishments. The findings revealed that servers who touched their patrons did receive larger gratuities than servers who did not touch their patrons. Further, in one setting, servers received larger tips from patrons who were of the opposite gender than from patrons who were of the same gender. These results support the ubiquitous influence of a fleeting touch on gratuities, and the possibility that, in certain situations, touch may be more advantageous when done by members of the opposite gender.     

The Diffusion of Youth-Led Participatory Research in Urban Schools: The Role of the Prevention Support System in Implementation and Sustainability

This article discusses the dissemination of a process of youth-led participatory research in urban secondary schools within the Interactive Systems Framework for Dissemination and Implementation (ISF) developed in collaboration with the CDC and its university partners (Wandersman et al. American Journal of Community Psychology, 41(3-4) 2008). The focus here is on the development of the Prevention Support System with respect to general and innovation-specific capacity building. The specific process under study involves youth-led needs assessment and research to inform the planning of prevention programs and policies to address students' health and developmental needs. The article first briefly describes the youth-led research process, its potential benefits, and a case example in two urban secondary schools. It then describes challenges and responses in providing support for the diffusion of this model in 6 secondary schools. The settings are urban public schools with a majority of students of color from diverse ethnic groups: Asian-American, Latino, and African-American. This project constitutes a collaborative partnership with a university school of public health and community-based organizations (CBOs) to build capacity for long-term, sustainable implementation of this innovative process within the local school system. The perspectives of the university-based researcher and the CBO partners on the development and effectiveness of the Prevention Support System are presented.     

Multi- and unisensory visual flash illusions

The role of stimulus structure in multisensory and unisensory interactions was examined. When a flash (17 ms) was accompanied by multiple tones (each 7 ms, SOA < or =100 ms) multiple flashes were reported, and this effect has been suggested to reflect the role of stimulus continuity in multisensory interactions. In experiments 1 and 2 we examined if stimulus continuity would affect concurrently presented stimuli. When a relatively longer flash (317 ms) was accompanied by multiple tones (each 7 ms), observers reported perceiving multiple flashes. In experiment 3 we tested whether a flash presented near fixation would induce an illusory flash further in the periphery. One flash (17 ms) presented 5 degrees below fixation was reported as multiple flashes if presented with two flashes (each 17 ms, SOA =100 ms) 2 degrees above fixation. The extent to which these data support a phenomenological continuity principle and whether this principle applies to unisensory perception is discussed.

Concurrent and lasting effects of emotion regulation on amygdala response in adolescence and young adulthood

This study used functional MRI (fMRI) to examine a novel aspect of emotion regulation in adolescent development: whether age predicts differences in both the concurrent and lasting effects of emotion regulation on amygdala response. In the first, active regulation, phase of the testing session, fMRI data were collected while 56 healthy individuals (age range: 10.50–22.92 years) reappraised aversive stimuli so as to diminish negative responses to them. After a short delay, the second, re‐presentation, phase involved passively viewing the aversive images from the reappraisal task. During active regulation, older individuals showed greater drops in negative affect and inverse rostrolateral prefrontal‐amygdala connectivity. During re‐presentation, older individuals continued to show lasting reductions in the amygdala response to aversive stimuli they had previously reappraised, an effect mediated by rostrolateral PFC. These data suggest that one source of heightened emotionality in adolescence is a diminished ability to cognitively down‐regulate aversive reactions.     

Effects of Physical Appearance Social Comparisons and Perceived Attainability of an Ideal Body on Body Dissatisfaction and Weight-Management Behaviors Among Young Japanese Women

This study was designed to test a model in which tendencies to engage in physical appearance social comparisons and perceived ideal body attainability interact to predict body dissatisfaction, and are associated with weight-control behaviors (WCBs) as past studies have rarely examined perceived attainability in their analytic models. College women (N = 297) from two universities in Japan completed a paper-and-pencil survey. A path analysis revealed that appearance comparisons were positively associated with body dissatisfaction over and above the effects of body mass index and self-esteem. Body dissatisfaction, in turn, was positively related to low-risk, moderate-risk, and high-risk WCBs. There was a significant interaction effect between appearance comparison and attainability, but the nature of the interaction was the opposite from our expectation: the positive association between appearance comparison and body dissatisfaction was more pronounced among women who reported higher confidence in attaining an ideal body, whereas this association was nonsignificant for those with low confidence in attaining an ideal body. Finally, perceived ideal body attainability was directly and positively related to low-risk and moderate-risk WCBs.     

Computational Theory and Cognition in Representational Momentum and Related Types of Displacement: A reply to Kerzel

Kerzel’s (2006) commentary on Hubbard’s (2005) re-view of the literature on representational momentum and related types of displacement highlights differences of interpretation between Hubbard and Kerzel, but also contains mischaracterizations of Hubbard’s position. In this reply to Kerzel, these differences and mischaracterizations are addressed. Issues are briefly considered that involve the following: whether displacement involves multiple processes; the Marr (1982) framework; the relationship of displacement to internalized physics, goodness of perceived motion, apparent motion, and oculomotor overshoot; generalization from flashed objects to moving objects; necessary and sufficient criteria for displacement; and whether the existence of auditory representational momentum provides evidence for a supramodal account of displacement.     

The role of storytelling in advertising: Consumer emotion,narrative engagement level,and word‐of‐mouth intention

This experimental study with a national online sample (n = 300) tested the effects of storytelling in radio advertisements on participants' positive emotional responses and intentions to share information about the product, depending on audiences' narrative engagement level. Treatments included a commercial for a fictitious brand of luggage using a story told by the founder of the company, another version of the same commercial manipulated so the speaker was a customer of the company, and a control stimulus consisting only of information about the product. Results showed that narrative transportation and narrative preference are positively associated with favorable responses toward ad. Stories elicited more favorable emotional responses and had some effect on participants' intention to share information about the product by word‐of‐mouth. This was especially true among participants hearing the founder's story. Results support previous assumptions about the power of storytelling in advertising, including distinctions regarding the identity of the speaker (founder vs. customer).     

Displacement in depth: Representational momentum and boundary extension

Memory for targets moving in depth and for stationary targets was examined in five experiments. Memory for targets moving in depth was displaced behind the target with slower target velocities (longer ISIS and retention intervals) and beyond the target with faster target velocities (shorter ISIS and retention intervals), and the overall magnitude of forward displacement for motion in depth was less than the overall magnitude of forward displacement for motion in the picture plane. Memory for stationary targets was initially displaced away from the observer, but memory for smaller stationary targets was subsequently displaced toward the observer and memory for larger stationary targets was subsequently displaced away from the observer; memory for the top or bottom edge of a stationary target was displaced inside the target perimeter. The data are consistent with Freyd and Johnson's (1987) two-component model of the time course of representational momentum and with Intraub et al.'s (1992) two-component model of boundary extension.
