Tumor Locus Moderates Anxiety Symptoms in a Pediatric Neuro-Oncologic Sample

Despite the prevalence of pediatric Central Nervous System (CNS) solid tumors, little is understood about patients' disease-related anxiety experience. Data from 25 remitted pediatric CNS tumor patients posttreatment were collected. Significant symptoms of anxiety were reported by 32% of patients. MRI studies showed all anxious patients had right cortical tumors or left cerebellar tumors. Confound analyses suggest these results are not better accounted for by demographic, disease, or treatment variables. These results evidence the risk some pediatric neuro-oncologic patients face for developing significant anxiety symptoms.     

The influence of discrete emotions on judgement and decision-making: a meta-analytic review

During the past three decades, researchers interested in emotions and cognition have attempted to understand the relationship that affect and emotions have with cognitive outcomes such as judgement and decision-making. Recent research has revealed the importance of examining more discrete emotions, showing that same-valence emotions (e.g., anger and fear) differentially impact judgement and decision-making outcomes. Narrative reviews of the literature (Lerner & Tiedens, 2006 ; Pham, 2007 ) have identified some under-researched topics, but provide a limited synthesis of findings. The purpose of this study was to review the research examining the influence of discrete emotions on judgement and decision-making outcomes and provide an assessment of the observed effects using a meta-analytic approach. Results, overall, show that discrete emotions have moderate to large effects on judgement and decision-making outcomes. However, moderator analyses revealed differential effects for study-design characteristics and emotion-manipulation characteristics by emotion type. Implications are discussed.     

Factor structure and longitudinal invariance of the Medical Adherence Report Scale-Asthma

Adequate assessment of adherence to medical treatment is critical for both research purposes and clinical practice. This study examined the factor structure and longitudinal invariance of the Medication Adherence Report Scale (MARS-A10) in a sample of asthmatic patients. We examined longitudinal data from 294 inner-city, adult participants with moderate to severe asthma. Because of ambiguous evidence regarding the dimensionality of the MARS-A10, the data was analysed with exploratory structural equation modelling. We first proceeded by determining the dimensionality of the scale at baseline and examined whether the structure, loadings, intercepts and errors were invariant over the four assessments points. Results indicated that a two-factor structure (factor 1: non-adherence based on experiential changes; factor 2: non-adherence based on intentional medication avoidance) had the best fit to the data (χ(2)(25)=37.69, p=0.05). Longitudinal analyses revealed that the nine items assessing intentional non-adherence were invariant over time. The evidence from the factor analysis suggests that intentional non-adherence is a multidimensional construct. Additionally, longitudinal data provided strong evidence that the items examining intentional non-adherence are invariant over time, indicating that changes in non-adherence scores can be validly attributed to changes in behaviour.     

Culture and importance of backgrounds: a cross-cultural study of photograph taking

To compare the focus on targeted people while taking a photograph, samples of American and Chinese college students were randomly selected and asked to take casual pictures of people around them with digital cameras. About 200 photographs were rated for the focus on the intended target in the picture. American students were more likely to focus on the targeted individual, while the Chinese students were more likely to attend to the background and the environment of the targeted individual. The findings imply that for the Chinese college students, the environment can be equally important as the person. Possibly for Americans the environment is less important due to the more individualistic culture.     

Supersize My Chances: Promotional Lotteries Impact Product Size Choices

Promotional lotteries offer consumers a chance to win one of many prizes along with their purchase. Critically, as is often the case, these campaigns not only include an assortment of prizes but also an assortment of offerings that one can buy to enter the lottery—such as a small or an extra‐large coffee. While companies regularly advertise that the objective odds of winning do not vary by the size of their product offerings, recent anecdotal evidence suggest that consumers behave as if it does. The net result is that consumers seem to be supersizing during promotional lotteries, and thus purchasing larger sized items. Eight studies (four core and four supplementary in Supporting information ) and a single‐paper meta‐analysis confirm that the supersizing phenomenon is indeed real and provides evidence that this behavior is the manifestation of consumers elevating their sense of control. Specifically, supersizing serves to gain psychological control over the pursuit of a desirable, but seemingly unobtainable, outcome.     

How Readability Shapes Social Media Engagement

We suggest that text readability plays an important role in driving consumer engagement on social media. Consistent with a processing fluency account, we find that easy‐to‐read posts are more liked, commented on, and shared on social media. We analyze over 4,000 Facebook posts from Humans of New York, a popular photography blog on social media, over a 3‐year period to see how readability shapes social media engagement. The results hold when controlling for photo features, story valence, and other content‐related characteristics. Experimental findings further demonstrate the causal impact of readability and the processing fluency mechanism in the context of a fictitious brand community. This research articulates the impact of processing fluency on brief word‐of‐mouth transmissions in the real world while empirically demonstrating that readability as a message feature matters. It also extends the impact of processing fluency to a novel behavioral outcome: commenting and sharing actions.     

When saying and doing diverge: The effects of stereotype threat on self-reported versus non-verbal anxiety

Although research has established that stigmatized individuals suffer impaired performance under stereotype threat conditions, the anxiety presumed to mediate this effect has proven difficult to establish. In the current investigation, we explored whether non-verbal measures would fare better than self-reports in capturing stereotype threat anxiety. Gay and heterosexual men interacted with preschool children under stereotype threat or control conditions. As predicted, stereotype-threatened gay men demonstrated more non-verbal anxiety, but not more self-reported anxiety, than non-threatened gays during these interactions. Furthermore, non-verbal anxiety appeared to mediate the effects of stereotype threat on the quality of participants’ childcare skills. We discuss how these findings advance stereotype threat research, and highlight their potential implications for gay childcare workers.     

A comparison of dense-to-lean and fixed lean schedules of alternative reinforcement and extinction

Behavior-reduction interventions typically employ dense schedules of alternative reinforcement in conjunction with operant extinction for problem behavior. After problem behavior is reduced in the initial treatment stages, schedule thinning is routinely conducted to make the intervention more practical in natural environments. In the current investigation, two methods for thinning alternative reinforcement schedules were compared for 3 clients who exhibited severe problem behavior. In the dense-to-lean (DTL) condition, reinforcement was delivered on relatively dense schedules (using noncontingent reinforcement for 1 participant and functional communication training for 2 participants), followed by systematic schedule thinning to progressively leaner schedules. During the fixed lean (FL) condition, reinforcement was delivered on lean schedules (equivalent to the terminal schedule of the DTL condition). The FL condition produced a quicker attainment of individual treatment goals for 2 of the 3 participants. The results are discussed in terms of the potential utility of using relatively lean schedules at treatment outset.
