Early Positive Information Impacts Final Evaluations: No Deliberation‐Without‐Attention Effect and a Test of a Dynamic Judgment Model

Evaluation judgments were affected by information order and not by subsequent unconscious versus conscious deliberation. In three experiments, we examined the influence of early positive information on final evaluations of four objects. Based on a task analysis, we predicted primacy effects in judgments in a sequential data acquisition task. Thinking periods following presentation were used to manipulate conscious or unconscious processing. In all three studies, we found no effects of thinking manipulations but instead found reliable order effects. We developed and tested an online judgment model on the basis of the belief updating model of Hogarth and Einhorn. The model accounted for large proportion of the individual level variability, and model comparison tests supported the presence of a primacy effect. Copyright © 2013 John Wiley & Sons, Ltd.     

Reasons Wrong and Right

The fact that someone is generous is a reason to admire them. The fact that someone will pay you to admire them is also a reason to admire them. But there is a difference in kind between these two reasons: the former seems to be the ‘right’ kind of reason to admire, whereas the latter seems to be the ‘wrong’ kind of reason to admire. The Wrong Kind of Reasons Problem is the problem of explaining the difference between the ‘right’ and the ‘wrong’ kind of reasons wherever it appears. In this article I argue that two recent proposals for solving the Wrong Kind of Reasons Problem do not work. I then offer an alternative solution that provides a unified, systematic explanation of the difference between the two kinds of reasons.     

Interactions between deliberation and delay-discounting in rats

When faced with decisions, rats sometimes pause and look back and forth between possible alternatives, a phenomenon termed vicarious trial and error (VTE). When it was first observed in the 1930s, VTE was theorized to be a mechanism for exploration. Later theories suggested that VTE aided the resolution of sensory or neuroeconomic conflict. In contrast, recent neurophysiological data suggest that VTE reflects a dynamic search and evaluation process. These theories make unique predictions about the timing of VTE on behavioral tasks. We tested these theories of VTE on a T-maze with return rails, where rats were given a choice between a smaller reward available after one delay or a larger reward available after an adjustable delay. Rats showed three clear phases of behavior on this task: investigation, characterized by discovery of task parameters; titration, characterized by iterative adjustment of the delay to a preferred interval; and exploitation, characterized by alternation to hold the delay at the preferred interval. We found that VTE events occurred during adjustment laps more often than during alternation laps. Results were incompatible with theories of VTE as an exploratory behavior, as reflecting sensory conflict, or as a simple neuroeconomic valuation process. Instead, our results were most consistent with VTE as reflecting a search process during deliberative decision making. This pattern of VTE that we observed is reminiscent of current navigational theories proposing a transition from a deliberative to a habitual decision-making mechanism.     

From alpha to omega: A practical solution to the pervasive problem of internal consistency estimation

Coefficient alpha is the most popular measure of reliability (and certainly of internal consistency reliability) reported in psychological research. This is noteworthy given the numerous deficiencies of coefficient alpha documented in the psychometric literature. This mismatch between theory and practice appears to arise partly because users of psychological scales are unfamiliar with the psychometric literature on coefficient alpha and partly because alternatives to alpha are not widely known. We present a brief review of the psychometric literature on coefficient alpha, followed by a practical alternative in the form of coefficient omega. To facilitate the shift from alpha to omega, we also present a brief guide to the calculation of point and interval estimates of omega using a free, open source software environment.     

A randomized controlled pilot trial of classroom-based mindfulness meditation compared to an active control condition in sixth-grade children

The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys, 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported measures included the Youth Self Report (YSR), a modified Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure –Revised. Both groups decreased significantly on clinical syndrome subscales and affect but did not differ in the extent of their improvements. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. These results suggest that mindfulness training may yield both unique and non-specific benefits that are shared by other novel activities.     

The role of analytic thinking in moral judgements and values

While individual differences in the willingness and ability to engage analytic processing have long informed research in reasoning and decision making, the implications of such differences have not yet had a strong influence in other domains of psychological research. We claim that analytic thinking is not limited to problems that have a normative basis and, as an extension of this, predict that individual differences in analytic thinking will be influential in determining beliefs and values. Along with assessments of cognitive ability and style, religious beliefs, and moral values, participants judged the wrongness of acts considered disgusting and conventionally immoral, but that do not violate care- or fairness-based moral principles. Differences in willingness to engage analytic thinking predicted reduced judgements of wrongness, independent of demographics, political ideology, religiosity, and moral values. Further, we show that those who were higher in cognitive ability were less likely to indicate that purity, patriotism, and respect for traditions and authority are important to their moral thinking. These findings are consistent with a “Reflectionist” view that assumes a role for analytic thought in determining substantive, deeply-held human beliefs and values.     

The influence of depression symptoms on exploratory decision-making

People with symptoms of depression show impairments in decision-making. One explanation is that they have difficulty maintaining rich representations of the task environment. We test this hypothesis in the context of exploratory choice. We analyze depressive and non-depressive participants’ exploration strategies by comparing their choices to two computational models: (1) an “Ideal Actor” model that reflectively updates beliefs and plans ahead, employing a rich representation of the environment and (2) a “Naïve Reinforcement Learning” (RL) model that updates beliefs reflexively utilizing a minimal task representation. Relative to non-depressive participants, we find that depressive participants’ choices are better described by the simple RL model. Further, depressive participants were more exploratory than non-depressives in their decision-making. Depressive symptoms appear to influence basic mechanisms supporting choice behavior by reducing use of rich task representations and hindering performance during exploratory decision-making.     

Act with authority: Romantic desire at the nexus of power possessed and power perceived

The social psychological literature and the evolutionary literature on power suggest different routes by which power might inspire romantic desire: the former highlights the appealing actions of the powerful, whereas the latter demonstrates that people desire powerful individuals upon learning of those individuals' powerful status. We predicted that, in an initial face-to-face interaction, both elements must align for the powerful to inspire romantic desire. In a live mixed-sex interaction, participants experienced the most romantic desire for an opposite-sex target who (a) actually possessed power and (b) was perceived by the participant to possess power. This interaction was mediated by observable behavior—the extent to which the target controlled the conversation and was given legitimacy by the group—indicating that the powerful do not behave powerfully around unaccommodating subordinates. Power manipulations implemented in only one person's mind may not approximate how power functions in real social interactions.     

Examining the Potential of Community-Based After-School Programs for Latino Youth

Results are presented from two pilot studies examining the potential influence of community-based after-school programs (ASPs) on regionally diverse Latino youth of varying ages. Study 1 examined relations between dimensions of ASP attendance and content, and ethnic identity development, and self-worth in urban Latino adolescents. In this study, higher ratings of the ASP’s emphasis on ethnic socialization were associated with a more developed ethnic identity, while greater intensity of ASP participation and perceptions of ASP quality were associated with higher levels of self-worth. Study 2 examined relations between ASP participation and development of concentration and emotion regulation skills in rural Latino grade-school youth. In this study, youth who regularly attended the ASP demonstrated significantly better concentration and regulation skills than those who did not regularly attend, if they exhibited preexisting concentration and regulation problems. Findings illustrate how ASPs with varying strategies, activities, and assessment tools can be evaluated in the interest of designing future large-scale investigations into ASPs and Latino positive youth development.
