On Measuring and Modeling Physiological Synchrony in Dyads

Physiological synchrony within a dyad, or the degree of temporal correspondence between two individuals' physiological systems, has become a focal area of psychological research. Multiple methods have been used for measuring and modeling physiological synchrony. Each method extracts and analyzes different types of physiological synchrony, where ‘type’ refers to a specific manner through which two different physiological signals may correlate. Yet, to our knowledge, there is no documentation of the different methods, how each method corresponds to a specific type of synchrony, and the statistical assumptions embedded within each method. Hence, this article outlines several approaches for measuring and modeling physiological synchrony, connects each type of synchrony to a specific method, and identifies the assumptions that need to be satisfied for each method to appropriately extract each type of synchrony. Furthermore, this article demonstrates how to test for between-dyad differences of synchrony via inclusion of dyad-level (i.e., time-invariant) covariates. Finally, we complement each method with an empirical demonstration, as well as online supplemental material that contains Mplus code.     

Weight,Perceptions, and Bullying: What Kind of Pounds Matter?

A great deal of research has investigated weight as a predictor for bullying victimization. However, weight is rarely examined in light of its potential role in explaining bullying perpetration, despite the fact that the definition of bullying typically requires a power imbalance, which can refer to either social power or physical size. Using negative binomial regressions, we investigated weight as a predictor of overt and relational bullying behaviors for a sample of 3208 6th–8th graders from 11 schools in a northeastern state. We examined whether this relationship differs by gender, and we explored whether objective size or perception of size is more predictive of perpetration. We also examined whether certain protective factors, like a positive school environment, moderated the effect of weight on bullying perpetration. We found that students who reported a higher BMI engaged in more overt, but not relational, bullying perpetration. Interestingly, students with misperceptions about their weight reported higher levels of both types of bullying perpetration, while students reporting a more positive school climate engaged in less overt and relational bullying. We also found gender differences in that girls are statistically more likely to commit overt bullying if they have a higher BMI. Our results suggest that prevention programs should address weight as a predictor of bullying behaviors, especially for girls, but also that body image and misperception of weight are important topics for prevention programs.     

A theoretical review of consumer priming: Prospective theory,retrospective theory,and the affective–behavioral–cognitive model

Primes are pervasive in marketing. Despite frequent use in practice, there has yet to be a framework to categorize priming techniques that is inclusive of measurement challenges and methods for administering primes as well as provides insight for researchers on how to think about and construct research using priming. Prior researchers have provided reviews of priming research, which have set the stage for discussions of priming theories and challenges of using primes in survey research. We build from their review and contribute in four ways by (i) reviewing priming theories rooted in both prospective and retrospective models of memory; (ii) developing a priming framework based on the ABC model of attitudes (affective, behavioral, and cognitive priming) that incorporates lexical priming, priming fluency effects, and methods for administering primes; (iii) addressing priming challenges including discrepancies between the priming method and measurement method; and (iv) positing the influence of personal characteristics on priming, such as the role of skepticism in assimilation and contrast effects. The final model is offered and elaborated upon as a guide for future research. Copyright © 2016 John Wiley & Sons, Ltd.     

Intrapersonal variation in consumer susceptibility to normative influence: toward a better understanding of brand choice decisions

The authors examined intrapersonal variation in consumer susceptibility to normative influence as a key mediator of wine brand choice. On the basis of a consumer sample, the authors found that individual values and social identity complexity affect consumer susceptibility to normative influence with downstream effects on (a) which brand benefits consumers desire in wine and (b) choice. Individuals higher on internal values and with more complex social identities were less susceptible to normative influence and placed less emphasis on social brand benefits. Separate examinations of consumption scenarios with and without salient reference groups showed that reference group salience interacts with personal values and social identity complexity in affecting consumer susceptibility to normative influence, which in turn affects which brand benefits consumers desire and consequently choice.     

Dialectical Thinking in Consumer Decision Making

In this article, we examine the four processes of dialectical thinking: interconnection, development and change, transformation of quantitative into qualitative, and unity and struggle of opposites. We argue that the decisions of some consumers reflect dialectical thinking, at least some of the time.     

Values,Susceptibility to Normative Influence,and Attribute Importance Weights: A Nomological Analysis

It is argued that the construct of individual susceptibility to normative influence (SNI) needs to be put into a wider nomological framework, with antecedents and consequences. Based on prior literature, a causal sequence is hypothesized in which values are antecedent to SNI, which itself shapes the importance placed by the individual on different attributes. It is further suggested that the relation between values and SNI is strongest for “external” values, and that high SNI leads to greater importance for attributes that provide “socially visible” benefits. Data from a national field survey (N= 663) on consumer preferences are analyzed to test these hypotheses, using confirmatory factor analysis via LISREL 8.30 (Jöreskog & Sörbom, 1993). The analysis finds support for most of the hypothesized structural relations.     

Cognitive Consequences of Legislating Postpurchase Behavior: Growing Up with the Bottle Bill

A study was conducted to understand how bottle bills exert their effect. Legislation does apparently allow for a situation in which behaviors influence attitudes if subjective norms converge with the new position. Students tested longitudinally manifested significant ( p < .1) differences in cross-lagged panel correlations implying that subjective norms lead to bottle bill and ecological attitudes, that behavior and habit lead to bottle returning attitudes, and that ecological attitudes lead to intentions. Students in Oregon were found to have greater pro-ecological attitudes than students in neighboring states. Public policy implications are discussed.
