We are more selfish than we think: The endowment effect and reward processing within the human medial-frontal cortex

Perceived ownership has been shown to impact a variety of cognitive processes: attention, memory, and—more recently—reward processing. In the present experiment we examined whether or not perceived ownership would interact with the construct of value—the relative worth of an object. Participants completed a simple gambling game in which they gambled either for themselves or for another while electroencephalographic data were recorded. In a key manipulation, gambles for oneself or for another were for either small or large rewards. We tested the hypothesis that value affects the neural response to self-gamble outcomes, but not other-gamble outcomes. Our experimental data revealed that while participants learned the correct response option for both self and other gambles, the reward positivity evoked by wins was impacted by value only when gambling for oneself. Importantly, our findings provide additional evidence for a self-ownership bias in cognitive processing and further demonstrate the insensitivity of the medial-frontal reward system to gambles for another.     

Adolescents in Transition to Adulthood: Parental Support, Relationship Satisfaction, and Post-transition Adjustment

The transition from high school is a pivotal period for intergenerational relations, as the asymmetry characterizing pre-transition relations with parents is reconfigured. Changes in adolescent–parent relations across this transition have potentially important implications for post-transition adjustment. A prospective study was conducted with an ethnically diverse sample that included adolescents who were not college-bound. Maternal, but not paternal, relations improved across the transition from high school to adult life. Changes in support from both mothers and fathers were associated with changes in relationship satisfaction and changes in satisfaction predicted post-transition adjustment. The results verify the importance of parental support to the quality of relational bonds between young adults and their parents. They also affirm the significance of these bonds for post-transition adjustment.     

Avoiding Late Preemption with the Right Kind of Influence

Philosophia - David Lewis championed a counterfactual account of causation, but counterfactual accounts have a notoriously difficult time handling cases of late preemption. These are cases in which...     

The texture of causal construals: Domain-specific biases shape causal inferences from discourse

We conducted five sets of experiments asking whether psychological and physical events are construed in broadly different manners concerning the underlying textures of their causes. In Experiments 1a–1d, we found a robust tendency to estimate fewer causes (but not effects) for psychological than for physical events; Experiment 2 showed a similar pattern of results when participants were asked to generate hypothetical causes and effects; Experiment 3 revealed a greater tendency to ascribe linear chains of causes (but not effects) to physical events; Experiment 4 showed that the expectation of linear chains was related to intuitions about deterministic processes; and Experiment 5 showed that simply framing a given ambiguous event in psychological versus physical terms is sufficient to induce changes in the patterns of causal inferences. Adults therefore consistently show a tendency to think about psychological and physical events as being embedded in different kinds of causal structures.     

The impact of parents, child care providers, teachers, and peers on early externalizing trajectories

This study utilized growth mixture modeling to examine the impact of parents, child care providers, teachers, and peers on the prediction of distinct developmental patterns of classroom externalizing behavior in elementary school. Among 241 children, three groups were identified. 84.6% of children exhibited consistently low externalizing behavior. The externalizing behavior of the Chronic High group (5.8%) remained elevated throughout elementary school; it increased over time in the Low Increasing group (9.5%). Negative relationships with teachers and peers in the kindergarten classroom increased the odds of having chronically high externalizing behavior. Teacher–child conflict increased the likelihood of a developmental pattern of escalating externalizing behavior. Boys were overrepresented in the behaviorally risky groups, and no sex differences in trajectory types were found.     

Assessing Readiness for Advancing Women Scientists Using the Transtheoretical Model

The under-representation of women in science, technology, engineering, and math disciplines is of wide interest. In this article we report on the development of new Transtheoretical Model-based measures to assess readiness to take action to advance women scientists. Reliable measures of Stage of Change, Decisional balance, and Self-efficacy were developed with a sample of science faculty from a northeastern university. Theoretical relationships among the constructs were validated and offer support for extending the Transtheoretical Model to this area. These measures are being used as part of a campus-wide initiative to examine the advancement of women scientists before and after a series of interventions.     

Trauma and Health Symptoms in a Community Sample: Examining the Influences of Gender and Daily Stress

Although there is a rich body of literature on trauma and health, limited research has investigated the variables of gender, trauma symptoms, physical health, mental health, and daily stress together in a community sample. Considering the deleterious effects of trauma on health, our overarching inquiry was whether trauma symptoms can predict overall mental and physical health with attention to gender and daily stress as potential moderators. Participants (n = 103; 50.5% women) completed self-report measures of trauma symptoms, mental health, physical health, and daily stress, along with demographic information. Trauma symptoms predicted 25.2% of the variance in general health symptoms. Gender significantly added to the variance accounted for, but daily stress was not significant in the model. Trauma symptoms predicted 37.1% of the variance in mental health symptoms. Daily stress significantly added to the model, but gender did not. Results are interpreted through the integration of family stress theory and feminist frameworks, adding to the literature by further illuminating the relationships between gender, daily stress, health symptoms, and trauma in a community sample.
