An appearance-based sun-protection intervention program was developed, implemented, and evaluated in a sample of 211 Caucasian women (ages 18-25) randomly assigned to the sun-protection program or to a stress management (control) program. The sun-protection program incorporated a novel construct of image norms of aspirational peers (i.e., female media figures, fashion models) approving paleness. The authors targeted these image norms as well as the advantages of tanning, health beliefs about photoaging and skin cancer, and self-efficacy for sun protection. The intervention produced significant differences across conditions favoring sun protection on all constructs but severity of skin cancer and barriers to sun protection. At follow-up, treatment participants exceeded controls both in intention to sun protect and sun-protective behavior and reported lower intention to sunbathe and fewer hours of sunbathing. A mediational model of intervention outcomes revealed distinct mediators for sun protection versus sunbathing.  相似文献

Previous studies of the perceptual processing and dynamics of emotional expression in faces have been limited by the lack of realistic yet controlled stimuli. The present work offers researchers a method for creating such stimuli for exploring these phenomena. We describe the creation of the stimuli and a series of experiments testing the validity of these stimuli with respect to emotional expressions in humans. Participants evaluated synthesized facial images and standardized photographs of six basic emotional expressions for intensity and accuracy of perceived emotion. Comparisons of these measures were qualitatively similar for synthesized and photographed faces. A manipulation of the magnitude of the synthesized expressions yielded a significant effect on the perceived intensity of expression. In a subsequent multidimensional scaling study, no systematic differences were uncovered in the derived configurations of the synthesized expressions and the photographs. These results are discussed in the context of possible future research applications.  相似文献

The present study is one of the first to empirically examine how the visual harmony of a questionnaire can lead to measurement bias. Researchers often employ questionnaires with Likert scales to measure constructs. In this note, we examine how the design of the survey instrument, specifically, its visual harmony, can impair measurement accuracy. Two studies investigate effects of visual harmony in surveys on responses to Likert scales using paper and pencil surveys. Applying an established customer relationship management model, Study 1 employs a survey of female visitors to a grocery store (n = 115). Switching to a product and brand innovation context, Study 2 employs a survey of male and female members of a consumer panel (n = 180) to examine responses to a new e‐scooter. Across studies, results indicate that assessing important consumer response constructs through visually more harmonious surveys can lead to more positive response patterns, lower scale reliability, and questionable validity, especially with females. Although these effects do not occur uniformly across measures and samples, they occur regardless of consumers' past experience with completing questionnaires, their familiarity with questionnaire design, and the naturalness and elaborateness of the visual design. Relating specific elements (e.g., text boxes, type font, shapes, and images) and relational properties of design (e.g., balance, symmetry, and coherence) to consumers' overall perception of harmony aids marketers and researchers in achieving intermediate levels to obtain realistic, reliable, and valid results.  相似文献

Treatments based on differential reinforcement of alternative behavior, such as functional communication training, are widely used. Research regarding the maintenance of related treatment effects is limited. Nevin and Wacker (2013) provided a conceptual framework, rooted in behavioral momentum theory, for the study of treatment maintenance that addressed two components: (a) reemergence of problem behavior, and (b) continued expression of appropriate behavior. In the few studies on this topic, focus has been on variables impacting the reemergence of problem behavior, with fewer studies evaluating the persistence of appropriate behavior. Given the findings from applied research related to functional communication training, variables related to response topography, such as response preference, may impact this aspect of maintenance. In the current study, the impact of response preference on persistence was evaluated in the context of functional communication training for individuals who did not exhibit problem behavior (Experiment 1) and for individuals with a history of reinforcement for problem behavior (Experiment 2). High‐preferred mands were more persistent than low‐preferred mands. These findings suggest that response related variables, such as response preference, impact response persistence and further suggest that response related variables should be considered when developing interventions such as functional communication training.  相似文献

The current study investigated bullying behaviors in 284 school children in the fourth through seventh grades at the time of the initial assessment. Peer ratings of bullying behavior were obtained at the end of the spring semester of one school year and at the end of the fall semester of the next school year. Importantly, peer ratings were obtained by assessing not only the level at which participants actually bully other students but also whether participants help bullies to hurt the victim (assister), encourage bullies (reinforce), or help the victim of bullying (defender). Our results did not support the utility of differentiating between bullies, assisters, or reinforcers. Specifically, these bullying roles were highly intercorrelated, both concurrently and across school years, and they showed similar correlations with aggression and several characteristics often associated with aggression (i.e., conduct problems, callous-unemotional traits, and positive expectancies about aggression). In contrast, ratings of defending designated a particularly prosocial group of students. Finally, whereas bullying appeared to be very similar in boys and girls, it was somewhat more stable across school years and was related to lower levels of prosocial behavior in boys, both of which could suggest that bullying may be somewhat more related to social group dynamics in girls.  相似文献

More than 13% of parents identify as being alienated by at least one of their children. Parental alienation often occurs after divorce when one parent (un)intentionally persuades his or her children to distance themselves from or reject the other parent. This study, couched in relational dialectics theory, explores the meaning of parenting from the perspective of 40 alienated parents. This analysis yielded two competing discourses: the culturally dominant discourse of parental norms (DPN) and the culturally marginalized discourse of parental victimization (DPV). Throughout the narrative interviews, the DPV resisted the DPN in four ways (diachronic separation, entertaining, countering, and negating). This study's findings provide insights into the perspective of the alienated parents, advance what we know about family distancing, and provide practical implications.  相似文献

Abstract

Objectives: To examine within-person and between-person sources of variation in the relationship between physical activity and cognition in older adults participating in a walking program. To explore whether demographic, health and fitness variables, and their interactions with activity, are significant predictors of cognition.

Design: Brief longitudinal burst design.

Participants: 118 participants (91 females, mean age?=?72.81?+ 5.24 years).

Main Outcome Measures: Cognition, self-reported moderate-to-vigorous walking and self-reported moderate-to-vigorous physical activity were assessed at baseline and 6, 9, 12 and 16 weeks follow-up. Attendance at weekly walks was also recorded.

Results: Within-persons, changes in physical activity were related to select measures of executive functioning, with increased activity predictive of better cognition (three of four cognitive functions, p<.05). Between-persons, activity was also associated with cognition (two of four cognitive functions, p<.05). Younger age and higher education were related to better cognition. Interactions of demographic, health, and fitness variables with changes in within-person activity were generally non-significant.

Conclusion: The results highlight the importance of distinguishing within- from between-person effects in longitudinal analyses of the association between physical activity and cognition. This stringent within-person test of association underscores the potential value of simple physical activity interventions for improving cognitive function.  相似文献
