The psychology of markets vs. hierarchies: The procedural fairness of alternative allocation procedures for benefits and burdens

This paper reports two studies examining the influence of social context on judgments about the fairness and desirability of two allocation mechanisms — markets and hierarchies. Two allocation contexts are compared: distributing benefits and burdens. The results show that people prefer to allocate burdens through markets and benefits through hierarchies. In both cases desirability is linked to procedural fairness, suggesting that people always prefer to use the fairer procedure for allocation, but view different procedures as fairer in these different contexts. Procedural fairness judgments were found to be linked to respondents' judgments about the impact of using different procedures to make allocations in each context, with people in each case preferring the procedure that they believe will have the most positive impact upon group cohesion. These findings suggest that what is construed as a fair procedure in one social context is not the same as what is construed as a fair procedure in another social context.     

Changes in spinal excitability during dual task performance

ABSTRACT The authors investigated how the nervous system responds to dual task performance. Because dual tasking is associated with greater postural challenges, it was hypothesized that spinal excitability would be reduced when simultaneously performing 2 tasks. For this experiment, participants maintained a lying or standing posture with or without performing a concurrent cognitive task (i.e., reacting to an auditory tone). Spinal excitability was assessed by eliciting the soleus Hoffmann reflex (H-reflex). Results indicated that the H-reflex was 6.4 ± 2.3% smaller (p = .011) when dual compared to single tasking. The reduced H-reflex amplitude, indicating a depressed spinal excitability, when dual tasking is suggested to reflect a neural strategy that individuals adopt to maintain postural stability when cognitive resources are divided between 2 concurrent tasks.     

Triggering self-presentation efforts outside of people's conscious awareness

Three studies utilized priming techniques to examine whether self-presentations can be activated without conscious awareness. The results across all experiments consistently demonstrated nonconscious self-presentation effects, in that people were unaware that their self-presentations were triggered automatically and that their self-presentations were comparable to participants who were explicitly instructed to self-present. The findings are novel because they are the first to demonstrate that self-presentations can be triggered without conscious awareness in a manner similar to self-presentations that are strategically selected. In addition, the results help undermine the common misconception that self-presentation typically involves conscious deliberation, pretense, or outright deception.     

Facets of Emotional Clarity and Suspiciousness

In a college student sample, we explored the relations between individual differences in facets of emotional clarity and suspiciousness. Previous theory and research has treated emotional clarity as a one-dimensional construct. Boden and Berenbaum (2011) proposed that a second facet of emotional clarity, source awareness (a general understanding of the cause of their emotions), could be distinguished from type awareness (a general understanding of the type of emotions [anger, fear] experienced). We found that source and type awareness were incrementally, inversely associated with suspiciousness when statistically accounting for the extent to which emotions are attended to, and gender. Additionally, source awareness significantly predicted suspiciousness after accounting for anger, anxious arousal, and social anxiety, whereas type awareness did not. Findings are consistent with the hypothesis that, among individuals with low source and type awareness, suspicious beliefs are formed to make sense of and explain emotional arousal.     

Informed Choice in Direct-to-Consumer Genetic Testing (DTCGT) Websites: A Content Analysis of Benefits,Risks, and Limitations

An informed choice about health-related direct-to-consumer genetic testing (DTCGT) requires knowledge of potential benefits, risks, and limitations. To understand the information that potential consumers of DTCGT services are exposed to on company websites, we conducted a content analysis of 23 health-related DTCGT websites. Results revealed that benefit statements outweighed risk and limitation statements 6 to 1. The most frequently described benefits were: 1) disease prevention, 2) consumer education, 3) personalized medical recommendations, and 4) the ability to make health decisions. Thirty-five percent of websites also presented at least one risk of testing. Seventy-eight percent of websites mentioned at least one limitation of testing. Based on this information, potential consumers might get an inaccurate picture of genetic testing which could impact their ability to make an informed decision. Practices that enhance the presentation of balanced information on DTCGT company websites should be encouraged.     

Age-related declines in the fidelity of newly acquired category representations

We present a theory suggesting that the ability to build category representations that reflect the nuances of category structures in the environment depends upon clustering mechanisms instantiated in an MTL-PFC-based circuit. Because function in this circuit declines with age, we predict that the ability to build category representations will be impaired in older adults. Consistent with this prediction, we find that older adults are impaired relative to younger adults at learning nuanced category structures that contain exceptions to the rule. Model-based analysis reveals that this deficit arises from older adults' failure to engage clustering mechanisms to separate exception and rule-following items in memory.     

Striatal and hippocampal entropy and recognition signals in category learning: simultaneous processes revealed by model-based fMRI

Category learning is a complex phenomenon that engages multiple cognitive processes, many of which occur simultaneously and unfold dynamically over time. For example, as people encounter objects in the world, they simultaneously engage processes to determine their fit with current knowledge structures, gather new information about the objects, and adjust their representations to support behavior in future encounters. Many techniques that are available to understand the neural basis of category learning assume that the multiple processes that subserve it can be neatly separated between different trials of an experiment. Model-based functional magnetic resonance imaging offers a promising tool to separate multiple, simultaneously occurring processes and bring the analysis of neuroimaging data more in line with category learning's dynamic and multifaceted nature. We use model-based imaging to explore the neural basis of recognition and entropy signals in the medial temporal lobe and striatum that are engaged while participants learn to categorize novel stimuli. Consistent with theories suggesting a role for the anterior hippocampus and ventral striatum in motivated learning in response to uncertainty, we find that activation in both regions correlates with a model-based measure of entropy. Simultaneously, separate subregions of the hippocampus and striatum exhibit activation correlated with a model-based recognition strength measure. Our results suggest that model-based analyses are exceptionally useful for extracting information about cognitive processes from neuroimaging data. Models provide a basis for identifying the multiple neural processes that contribute to behavior, and neuroimaging data can provide a powerful test bed for constraining and testing model predictions.     

Is Conservative Religiousness Inherently Associated with Poorer Health for Sexual Minorities?

Results of path analysis involving sexual minority participants (N?=?1317) from diverse sociopolitical contexts revealed health outcomes to be associated with internalized homonegativity and the resolution of conflict between religious and sexual minority identities. Contrary to expectations, several markers of religiousness were not directly associated with either improved or worsened health outcomes for depression or anxiety. However, religious activity moderated the influence of internalized homonegativity (IH) on depression such that IH was less strongly related to depression among individuals who frequently attended religious services than among individuals who infrequently attended religious services. These findings have special salience for advancing a more accurate understanding of conservatively religious sexual minorities and directing culturally sensitive research, clinical services, and public policy.

     

A Comparison of Rubrics for Identifying Empirically Supported Practices with Single-Case Research

The use of single-case research methods for validating academic and behavioral interventions has gained considerable attention in recent years. As such, there has been a proliferation of methods for evaluating whether, and to what extent, primary research reports provide evidence of intervention effectiveness. Despite the recent interest in harnessing single-case research to identify empirically supported strategies, examination of these tools has revealed that there is a lack of consistency in the methodological criteria sampled and scoring procedures used to evaluate primary research reports. The present study examined the extent to which various evidence rubrics addressed specific methodological features of single-case research and classified studies into similar evidence categories. Results indicated that the methodological criteria included within rubrics tended to vary, particularly for criteria related to determining the generality of the intervention under study. Moreover, there was substantial discordance observed in the evidence classifications assigned to reviewed studies. These findings are discussed in the context of the still-developing nature of single-case evidence reviews. Recommendations for both research and practice are provided.
