Does effort influence inequity aversion in cotton-top tamarins (Saguinus oedipus)?

The human sense of fairness entails sensitivity not just to equality, the equal division of resources, but also to merit, the relationship between an individual’s share of resources and how hard they worked for their share. Recent evidence suggests that our sensitivity to equality has deep phylogenetic roots: several nonhuman animal species show an aversion to unequal reward distributions. However, the extent to which nonhuman animals share sensitivity to merit remains poorly understood, largely because previous studies have failed to properly manipulate work effort in inequity aversion tasks. Here, we tested whether cotton-top tamarins (Saguinus oedipus) would exhibit a differential response to inequity when acquiring rewards was either (1) effortful or (2) effortless. Subjects engaged in a pulling task in which they had an opportunity to deliver a disadvantageously unequal distribution of food to themselves and a partner (one piece for self, four pieces for partner). We made delivery effortful by adding a weight to the pulling handle. Critically, effort was calibrated to each individual. Results show that individuals varied markedly in their response to effort, highlighting the importance of manipulating work effort at the individual level. Overall, subjects showed little aversion to inequity. However, subjects were slightly less likely to accept inequity when doing so was effortful, although this effect was pronounced in only one individual. Our findings suggest a new method for capturing individual variation in effort and for studying the roots of the concept of merit in nonhuman animals.     

Is pressure stressful? The impact of pressure on the stress response and category learning

We examined the basic question of whether pressure is stressful. We proposed that when examining the role of stress or pressure in cognitive performance, it is important to consider the type of pressure, the stress response, and the aspect of cognition assessed. In Experiment 1, outcome pressure was not experienced as stressful but did lead to impaired performance on a rule-based (RB) category-learning task, but not on a more procedural information-integration (II) task. In Experiment 2, the addition of monitoring pressure resulted in a modest stress response to combined pressure and impairment on both tasks. Across experiments, higher stress appraisals were associated with decreased performance on the RB, but not on the II, task. In turn, higher stress reactivity (i.e., heart rate) was associated with enhanced performance on the II, but not on the RB, task. This work represents an initial step toward integrating the stress cognition and pressure cognition literatures and suggests that integrating these fields may require consideration of the type of pressure, the stress response, and the cognitive system mediating performance.     

Examining the Effects of Incremental Case Presentation and Forecasting Outcomes on Case-Based Ethics Instruction

Case-based reasoning has long been used to facilitate instructional effectiveness. Although much remains to be known concerning the most beneficial way to present case material, recent literature suggests that simplifying case material is favorable. Accordingly, the current study manipulated two instructional techniques, incremental case presentation and forecasting outcomes, in a training environment in an attempt to better understand the utility of simplified versus complicated case presentation for learning. Findings suggest that pairing these two cognitively demanding techniques reduces satisfaction and detracts from the effectiveness of the learning approach. Implications regarding the use of instructional techniques in training programs are discussed.     

Health-Related Hindrance of Personal Goals of Adolescents with Cancer: The Role of the Interaction of Race/Ethnicity and Income

This study examined the interaction of race/ethnicity and income to health-related hindrance (HRH) of personal goals of adolescents with cancer. Adolescents (N = 94) receiving treatment for cancer completed a measure of HRH, (including identification of personal goals, rating the impact of health on goal pursuit, and ratings of goal appraisals). The interaction of race/ethnicity and income on HRH was examined. Goal content and appraisal were compared by race/ethnic groups. The interaction between race/ethnicity and income was significant in predicting HRH, with HRH increasing for minority adolescents as income increases and HRH decreasing for white adolescents as income increases. Higher income minority adolescents reported the most goals. Low income minorities reported the least difficult goals. Goal content did not differ between groups. Sociodemographic factors contribute to HRH in adolescents with cancer. Structural and psychosocial support during treatment to maintain goal pursuit may improve psychosocial outcomes.     

Toward a Phenomenology of Mood

Martin Heidegger's account of attunement [Befindlichkeit] through mood [Stimmung] is unprecedented in the history of philosophy and groundbreaking vis‐à‐vis contemporary accounts of emotion. On his view, moods are not mere mental states that result from, arise out of, or are caused by our situation or context. Rather, moods are fundamental modes of existence that are disclosive of the way one is or finds oneself [sich befinden] in the world. Mood is one of the basic modes through which we experience the world and through which the world is made present to us. Moreover, moods are the lenses through which things, people, animals, events, and aspects in the world matter to us. In this paper, I make the case that Heidegger's insights with respect to mood can and ought to be extended beyond the narrow scope of his fundamental ontology (in Being and Time) in which they were developed. I argue that contemporary accounts of mood within psychology ought to take these Heideggerian insights seriously and use them when defining, studying, evaluating, and drawing conclusions about the nature of moods. There are three sections to my paper. In section 1, I delineate Heidegger's account of mood. In section 2, I turn to some key studies on mood in psychology, and I elaborate upon some of the main shortcomings in this literature. In section 3, I suggest how psychology might benefit from understanding and utilizing a Heideggerian‐inspired phenomenology of mood.     

Children's Sensitivity to Ulterior Motives When Evaluating Prosocial Behavior

Reasoning about ulterior motives was investigated among children ages 6–10 years (total N = 119). In each of two studies, participants were told about children who offered gifts to peers who needed help. Each giver chose to present a gift in either a public setting, which is consistent with having an ulterior motive to enhance one's reputation, or in a private setting, which is not consistent with having an ulterior motive. In each study, the 6‐ to 7‐year olds showed no evidence of understanding that the public givers might have ulterior motives, but the 8‐ to 10‐year olds rated the private givers more favorably. In 3. , the older children were more likely than the younger children to refer to impression management when explaining their judgments of the givers. The younger children who mentioned impression management did so to justify a preference for public givers (e.g., by explaining that public givers are nicer because more of their peers will know that they are nice). Results from 4. suggest that developmental change in children's reasoning about intentions and social outcomes contributes to their understanding of ulterior motives.     

A Dyadic Perspective on Speech Accommodation and Social Connection: Both Partners' Rejection Sensitivity Matters

Findings from confederate paradigms predict that mimicry is an adaptive route to social connection for rejection‐sensitive individuals (Lakin, Chartrand, & Arkin, 2008). However, dyadic perspectives predict that whether mimicry leads to perceived connection depends on the rejection sensitivity (RS) of both partners in an interaction. We investigated these predictions in 50 college women who completed a dyadic cooperative task in which members were matched or mismatched in being dispositionally high or low in RS. We used a psycholinguistics paradigm to assess, through independent listeners' judgments (N = 162), how much interacting individuals accommodate phonetic aspects of their speech toward each other. Results confirmed predictions from confederate paradigms in matched RS dyads. However, mismatched dyads showed an asymmetry in levels of accommodation and perceived connection: Those high in RS accommodated more than their low‐RS partner but emerged feeling less connected. Mediational analyses indicated that low‐RS individuals' nonaccommodation in mismatched dyads helped explain their high‐RS partners' relatively low perceived connection to them. Establishing whether mimicry is an adaptive route to social connection requires analyzing mimicry as a dyadic process influenced by the needs of each dyad member.     

Still standing out: children's names in the United States during the Great Recession and correlations with economic indicators

Continuing a long‐standing trend in the U.S. Social Security Administration database of first names (N = 358 million), American parents were less likely to choose common names for their children between 2004 and 2015, including the years of the Great Recession (2008–2010). These trends were similar in California (severely affected by the recession) and Texas (less affected). Over a longer time period (1901–2015), cyclical economic indicators were either not correlated with common names (e.g., stock market performance) or worse economic times predicted fewer common names. The results are consistent with increasing individualism, with limited support for the idea that economic threat leads people to embrace uniqueness and no real support for the idea that economic deprivation leads to more communal name choices.
