I'll have what she's having: the impact of model characteristics on children's food choices

This research investigates children's use of social categories in their food selection. Across three studies, we presented preschoolers with sets of photographs that contrasted food-eating models with different characteristics, including model gender, race (Black, White), age (child or adult), and/or expression (acceptance or rejection of the food). Children were asked to pick between the photographs to choose which food they would like for snack. Results demonstrated that preschoolers prefer foods being eaten by models with positive over negative expressions, foods being eaten by child over adult models, and foods being eaten by child models of the same gender as themselves over models of the other gender. This work connects with previous research on children's understanding of social categories and also has important practical implications for how characteristics of a food-eating model can affect children's willingness to try new foods.     

Examining the Impact of Dons Providing Peer Instruction for Academic Integrity: Dons’ and Students’ Perspectives

A peer instruction model was used whereby 78 residence dons (36 males, 42 females) provided instruction regarding academic integrity for 324 students (125 males, 196 females) under their supervision. Quantitative and qualitative analyses were conducted to assess survey responses from both the dons and students regarding presentation content, quality, and learning. Overall, dons consistently identified information-based slides about academic integrity as the most important material for the presentations, indicating that fundamental information was needed. Although student ratings of the usefulness of the presentations were middling, students did indicate knowledge gains. Both interest and personal value for academic integrity were highly predictive of positive evaluations of the presentations. Dons and students provided suggestions for improvement and identified more global concerns.     

Roles of domain knowledge and working memory capacity in components of skill in Texas Hold’Em poker

Domain knowledge is a powerful predictor of success in many complex tasks, but do general cognitive abilities also play a role? To investigate this question, we had 155 participants representing a wide range of poker experience and skill complete tests of poker knowledge, working memory capacity (WMC), and two components of skill in Texas Hold’Em poker: the ability to remember hands and the ability to evaluate hands. Not surprisingly, poker knowledge positively predicted performance in all of the Hold’Em tasks. However, WMC added significantly to the prediction, and there was no evidence for interactions between poker knowledge and WMC. That is, WMC was as important as a predictor of performance at high levels of poker knowledge as at low levels, suggesting that domain knowledge may not always enable circumvention of WMC in domain-relevant tasks.     

Despair and the determinate negation of Brandom’s Hegel

In this paper, I contend that Brandom’s interpretive oversights leave his inferentialist program vulnerable to Hegelian critique. My target is Brandom’s notion of “conceptual realism,” or the thesis that the structure of mind-independent reality mimics the structure of thought. I show, first, that the conceptual realism at the heart of Brandom’s empiricism finds root in his interpretation of Hegel. I then argue that conceptual realism is incompatible with Hegel’s thought, since the Jena Phenomenology, understood as a “way of despair,” includes a critique of the philosophical framework upon which conceptual realism relies. Finally, I offer the Hegelian critique of Brandom that results from these textual infidelities.     

Social benefits of humility: Initiating and maintaining romantic relationships

Previous research has highlighted the social nature of humility. In three studies, we provide evidence that humility facilitates the initiation and maintenance of romantic relationships. In Study 1, very humble potential dating partners, relative to less humble partners, were rated more favorably and were more likely to elicit intentions to initiate a romantic relationship. Study 2 was a conceptual replication of Study 1 that provided evidence that participants find humble potential dating partners more attractive than arrogant dating partners. In Study 3, we examined perceptions of humility in participants in proximal or long-distance relationships. We found that humility buffers against unforgiveness in long-distant relationships. Although long-distance relationships were associated with greater unforgiveness, this effect was only present when partners were viewed as having low humility. Together, these findings highlight the social benefits of humility in initiating and maintaining romantic relationships.     

Religious Coping,Coping Resources,and Depressive Symptoms: Test of a Mediation Model

This study examined the relationships between religious coping, coping resources, and depressive symptoms. The authors tested whether coping resources explained the link between religious coping and depressive symptoms in a sample of 349 college students. Results indicated that coping resources partially mediated the relationship between negative religious coping and depressive symptoms, primarily through decreased social ease. The results offered no evidence that coping resources mediated the relationship between positive religious coping and depressive symptoms.     

One and Done? Optimal Decisions From Very Few Samples

In many learning or inference tasks human behavior approximates that of a Bayesian ideal observer, suggesting that, at some level, cognition can be described as Bayesian inference. However, a number of findings have highlighted an intriguing mismatch between human behavior and standard assumptions about optimality: People often appear to make decisions based on just one or a few samples from the appropriate posterior probability distribution, rather than using the full distribution. Although sampling‐based approximations are a common way to implement Bayesian inference, the very limited numbers of samples often used by humans seem insufficient to approximate the required probability distributions very accurately. Here, we consider this discrepancy in the broader framework of statistical decision theory, and ask: If people are making decisions based on samples—but as samples are costly—how many samples should people use to optimize their total expected or worst‐case reward over a large number of decisions? We find that under reasonable assumptions about the time costs of sampling, making many quick but locally suboptimal decisions based on very few samples may be the globally optimal strategy over long periods. These results help to reconcile a large body of work showing sampling‐based or probability matching behavior with the hypothesis that human cognition can be understood in Bayesian terms, and they suggest promising future directions for studies of resource‐constrained cognition.
