Working memory demands of exact and approximate addition

We compared the working memory requirements of two forms of mental addition: exact calculation (e.g., 63 + 49 = 112) and approximation (e.g., 63 + 49 is about 110). In two experiments, participants solved two-digit addition problems (e.g., 63 + 49) alone and in combination with a working memory task (i.e., remembering four consonants). In Experiment 1, participants chose an answer from two alternatives (e.g., exact: 112 vs. 122; approximate: 110 vs. 140). In Experiment 2, participants responded verbally with exact or approximate answers. In both experiments, the working memory load impaired exact and approximate addition performance, but exact addition was affected more. Load also impaired performance on problems with a carry operation in the units (e.g., 28 + 59 or 76 + 57) more than on problems without a unit carry (e.g., 24 + 53 or 76 + 52). These results identify the carry operation as the source of the working memory demands in multidigit addition.     

Sexuality and Religious Commitment in the United States: An Empirical Examination

I provide an empirical assessment of the religious commitments of gays, lesbians, and bisexuals in the United States. I compare the religiosity of gay men and lesbians and bisexuals to each other and to male and female heterosexuals, while controlling for a host of sociodemographic factors that may contribute to differences across the gender/sexuality groups. To accomplish this, I examine data from the 1991–2000 General Social Surveys (GSS). During this period, the GSS asked respondents for the sex of their sex partners over the last five years. The GSS finds that 4.3 percent of men and 3.1 percent of women report same-sex sexual partners in the five years preceding the interview—this is a larger proportion than members of "other" races, Episcopalians, or Jews. I find that gay men have high rates of religious participation, while lesbians and bisexuals have significantly lower rates of participation. Nonheterosexuals are more likely to become apostates when compared to female heterosexuals, but no more so than are heterosexual men. My findings are at odds with religious pundits who suggest that alternative sexuality mixes with religion more often for females than for males. The results are in concert with contemporary theories regarding the formation of religious preferences, and risk preferences and religiosity.     

Misrepresentation in the Consumer Context

Research in social psychology suggests that motives such as self‐bolstering and impression management can lead people to engage in deliberate misrepresentations during interpersonal communications. This article extends our understanding of such behavior to a new domain; that of consumer communications. Drawing on research on lying behavior and symbolic consumption, we suggest that misrepresentation about products and possessions is particularly likely to occur when these products or possessions are used to create a positive self‐image in the context of social interaction. Experiments 1 and 2 simulate a social interaction wherein misrepresentation about the purchase price of a product helps participants to manage impressions. A third experiment extends these findings by testing for wealth‐related misrepresentation in the context of an interaction wherein participants actually communicate their family's wealth to a recipient. Consistent with predictions derived from existing research on symbolic consumption, all 3 experiments provide support for the critical importance of recipient status on the likelihood of misrepresentation. The first 2 experiments additionally examine the role of individual differences and brand differences. Results on these dimensions are also supportive of our underlying theoretical premise regarding the antecedents of lying behavior.     

Fairness and Discounts: The Subjective Value of a Bargain

In this work, we examined the surprising value consumers attach to getting a bargain. Past research has largely understood this phenomenon in terms of the impact discounts have on perceptions of fairness. However, the evidence for this explanation is inconclusive due to a number of viable alternatives as well as issues relating to construct and external validity. The experiments we report here provide clearer evidence for the basic assertion that discounts increase purchase satisfaction due to the nonfinancial rewards that are associated with perceptions of fairness. Furthermore, current notions of fairness in the promotion literature are extended by showing that social cues such as the relative size of the discount received by another customer and the loyalty status of that customer can also have an important impact on fairness and purchase satisfaction. We suggest an integration of transaction utility theory (Thaler, 1985) and equity theory (Bagozzi, 1975) to account for these findin     

Is Political Cognition Like Riding a Bicycle? How Cognitive Neuroscience Can Inform Research on Political Thinking

Our understanding of political phenomena, including political attitudes and sophistication, can be enriched by incorporating the theories and tools of cognitive neuroscience—in particular, the cognitive neuroscience of nonconscious habitual cognition (akin to bicycle riding). From this perspective, different types of informational "building blocks" can be construed from which different types of political attitudes may arise. A reflection-reflexion model is presented that describes how these blocks combine to produce a given political attitude as a function of goals, primes, expertise, and inherent conflict in considerations relevant to the attitude. The ways in which neuroimaging methods can be used to test hypotheses of political cognition are reviewed.     

Burning With Envy? Dispositional and Situational Influences on Envy in Grandiose and Vulnerable Narcissism

Research on narcissism and envy suggests a variable relationship that may reflect differences between how vulnerable and grandiose narcissism relate to precursors of envy. Accordingly, we proposed a model in which dispositional envy and relative deprivation differentially mediate envy's association with narcissistic vulnerability, grandiosity, and entitlement. To test the model, 330 young adults completed dispositional measures of narcissism, entitlement, and envy; one week later, participants reported on deprivation and envy feelings toward a peer who outperformed others on an intelligence test for a cash prize (Study 1) or earned higher monetary payouts in a betting game (Study 2). In both studies, structural equation modeling broadly supported the proposed model. Vulnerable narcissism robustly predicted episodic envy via dispositional envy. Entitlement—a narcissistic facet common to grandiosity and vulnerability—was a significant indirect predictor via relative deprivation. Study 2 also found that (a) the grandiose leadership/authority facet indirectly curbed envy feelings via dispositional envy, and (b) episodic envy contributed to schadenfreude feelings, which promoted efforts to sabotage a successful rival. Whereas vulnerable narcissists appear dispositionally envy‐prone, grandiose narcissists may be dispositionally protected. Both, however, are susceptible to envy through entitlement when relative deprivation is encountered.     

Sexuality and Religious Commitment Revisited: Exploring the Religious Commitments of Sexual Minorities, 1991–2014

Research on the religious commitments of sexual minorities has burgeoned over the last two decades, yet most studies come from small convenience samples of people actively engaged in religious groups. This study provides an empirical examination of the religiosity of people who report having had same‐sex relations in the last five years using respondents from the General Social Survey (1991–2014) and provides a comparison to respondents from 2008 to 2014 who report their sexual identification as bisexual, gay, or lesbian. All comparisons are made by gender, and compared with male and female heterosexuals. The relationship between behavioral sexuality and religiosity is examined across time periods, distinguishing respondents from 1991 to 2002 from respondents interviewed in 2004–2014. Religious factors examined include religious identification, religious participation, prayer frequency, beliefs about the Bible, beliefs about God, and belief in an afterlife. Multivariate models are estimated to examine whether sociodemographic factors contribute to differences across the gender/sexuality groups.
