Evaluation of a multicomponent appearance-based sun-protective intervention for young women: uncovering the mechanisms of program efficacy.

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.     

Homogeneity computation: How interitem similarity in visual short-term memory alters recognition

Visual short-term recognition memory for multiple stimuli is strongly influenced by the study items’ similarity to one another—that is, by their homogeneity. However, the mechanism responsible for this homogeneity effect has remained unclear. We evaluated competing explanations of this effect, using controlled sets of Gabor patches as study items and probe stimuli. Our results, based on recognition memory for spatial frequency, rule out the possibility that the homogeneity effect arises because similar study items are encoded and/or maintained with higher fidelity in memory than dissimilar study items are. Instead, our results support the hypothesis that the homogeneity effect reflects trial-by-trial comparisons of study items, which generate a homogeneity signal. This homogeneity signal modulates recognition performance through an adjustment of the subject’s decision criterion. Additionally, it seems the homogeneity signal is computed prior to the presentation of the probe stimulus, by evaluating the familiarity of each new stimulus with respect to the items already in memory. This suggests that recognition-like processes operate not only on the probe stimulus, but on study items as well.     

Orangutans (Pongo spp.) may prefer tools with rigid properties to flimsy tools

Preference for tools with either rigid or flexible properties was explored in orangutans (Pongo spp.) through an extension of D. J. Povinelli, J. E. Reaux, and L. A. Theall's (2000) flimsy-tool problem. Three captive orangutans were presented with three unfamiliar pairs of tools to solve a novel problem. Although each orangutan has spontaneously used tools in the past, the tools presented in this study were novel to the apes. Each pair of tools contained one tool with rigid properties (functional) and one tool with flimsy properties (nonfunctional). Solving the problem required selection of a rigid tool to retrieve a food reward. The functional tool was selected in nearly all trials. Moreover, two of the orangutans demonstrated this within the first test trials with each of the three tool types. Although further research is required to test this statistically, it suggests either a preexisting preference for rigid tools or comprehension of the relevant features required in a tool to solve the task. The results of this study demonstrate that orangutans can recognize, or learn to recognize, relevant tool properties and can choose an appropriate tool to solve a problem.     

Salience of Anti-Abortion Beliefs and Commitment to an Attitudinal Position: On the Strength,Structure, and Predictive Validity of Anti-Abortion Attitudes1

The role of beliefs in attitude formation and the impact of commitment to an attitude on its predictive validity were studied in the context of anti-abortion attitudes. Undergraduates (N= 152), identified as pro-choice or pro-life, expressed their beliefs, attitudes, intentions, and restriction preferences with respect to making abortion illegal. In addition, they indicated their commitment to their positions and their willingness to distribute a pro- or anti-abortion petition. Salient beliefs—identified in a pilot study—were found to predict attitudes, intentions, restriction preferences, and petition choice significantly better than nonsalient beliefs. Salient beliefs also discriminated significantly between pro-choice and pro-life respondents, providing useful information about the cognitive underpinnings of anti-abortion attitudes. In addition, accuracy of predictions increased significantly with commitment, even when attitude extremity was statistically controlled. These findings support the summation theory of attitude (Fishbein, 1963) and demonstrate the importance of attitude strength in determining the structure and predictive validity of attitudes.     

Effects of response preference on resistance to change

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.     

A Case-Series of Reflective Family Play: Therapeutic Process,Feasibility, and Referral Characteristics

Evidence-based interventions for infants and preschoolers, and their families, have largely focused on the mother-child dyad. In response to the increasing need to diversify treatment approaches in the under six population and include the whole family system, we have developed a new treatment approach called Reflective Family Play (RFP). A manualized, whole-family therapy, RFP allows for the involvement of two parents and siblings when working with infants or young children. In this case-series, we used a qualitative chart review to examine the therapeutic process, acceptability, and feasibility of RFP for 22 families with children ages 0–6, who participated in RFP. We also sought to better understand the referral characteristics of those families who participated in RFP by comparing them to families who were referred to and participated in an established dyadic approach during the same time-period. Session-by-session coding of clinician chart notes revealed evidence of positive shifts throughout the RFP process, including more whole-family play, improvements in coparenting, and better parental mentalization. Parents reported improvements in presenting concerns in all but one case. Improvements in coparenting, sibling relationships, and family alliance were also reported by parents after RFP. Clinical implications and directions for future research are discussed.     

Configurations of Young Peoples’ Important Life Goals and Their Associations with Thriving

The aims of this study were to determine whether, and how, young people’s beyond-the-self life goals coexisted with other life goals, and whether having at least one beyond-the-self goal was associated with higher thriving (the Five Cs of Positive Youth Development [PYD]) and volunteering, compared to having either no goals, or goals that were only self-focused. The authors conducted latent class analyses among five school cohort groups using data from five studies (combined using integrative data analysis techniques). Across grade groups, the authors identified classes, which can generally be characterized by (1) low endorsement of goals, (2) prominence of helping others and contributing to community goals, (3) prominence of goals related to a good life (e.g., make money, friends, live an adventurous life), and (4) endorsement of most life goals. In the older two grade groups we identified additional classes: a group with a high endorsement of goals oriented at helping others and serving God/higher power in the undergraduate group, and a group with high endorsement of goals to create something new and make the world a better place in the graduate group. There were differences in the Five Cs of PYD and volunteering between the classes. The authors discuss the implications of these results for future research and practice regarding young people’s life goals.
