Buyer's remorse or missed opportunity? Differential regrets for material and experiential purchases

Previous research has established that experiential purchases tend to yield greater enduring satisfaction than material purchases. The present work suggests that this difference in satisfaction is paralleled by a tendency for material and experiential purchases to differ in the types of regrets they elicit. In 5 studies, we find that people's material purchase decisions are more likely to generate regrets of action (buyer's remorse) and their experiential purchase decisions are more likely to lead to regrets of inaction (missed opportunities). These results were not attributable to differences in the desirability of or satisfaction provided by the two purchase types. Demonstrating the robustness of this effect, we found that focusing participants on the material versus experiential properties of the very same purchase was enough to shift its dominant type of regret. This pattern of regret is driven by the tendency for experiences to be seen as more singular--less interchangeable--than material purchases; interchangeable goods tend to yield regrets of action, whereas singular goods tend to yield regrets of inaction.     

Brown on infallibilism’s problem with testimony

Philosophical Studies - In this review I focus on one of Brown’s arguments against infallibilism. While Brown argues that the infallibilist cannot vindicate testimonial knowledge, I argue...     

Socio-functional foundations in science: The case of measurement

We present a novel kind of “socio-functional” foundationalism rooted in the division of scientific labor. Our foundationalism is social in that it involves a socio-epistemic phenomenon we dub epistemic outsourcing, whereby claims from one group of scientists provide epistemological foundations for another group of scientists. We argue that: (1) epistemic outsourcing results in a legitimate form of epistemic foundationalism, (2) this sort of foundationalism can be used to shed light on the epistemology of measurement; and (3) epistemic outsourcing is a distinctively collective epistemic phenomenon.     

INTERPERSONAL EPISTEMIC ENTITLEMENTS

In this paper I argue that the nature of our epistemic entitlement to rely on certain belief‐forming processes—perception, memory, reasoning, and perhaps others—is not restricted to one's own belief‐forming processes. I argue as well that we can have access to the outputs of others’ processes, in the form of their assertions. These two points support the conclusion that epistemic entitlements are “interpersonal.” I then proceed to argue that this opens the way for a non‐standard version of anti‐reductionism in the epistemology of testimony, and a more “extended” epistemology—one that calls into question the epistemic significance that has traditionally been ascribed to the boundaries separating individual subjects.     

A self-referential default brain state: patterns of coherence,power, and eLORETA sources during eyes-closed rest and Transcendental Meditation practice

Activation of a default mode network (DMN) including frontal and parietal midline structures varies with cognitive load, being more active during low-load tasks and less active during high-load tasks requiring executive control. Meditation practices entail various degrees of cognitive control. Thus, DMN activation patterns could give insight into the nature of meditation practices. This 10-week random assignment study compared theta2, alpha1, alpha2, beta1, beta2 and gamma EEG coherence, power, and eLORETA cortical sources during eyes-closed rest and Transcendental Meditation (TM) practice in 38 male and female college students, average age 23.7 years. Significant brainwave differences were seen between groups. Compared to eyes-closed rest, TM practice led to higher alpha1 frontal log-power, and lower beta1 and gamma frontal and parietal log-power; higher frontal and parietal alpha1 interhemispheric coherence and higher frontal and frontal-central beta2 intrahemispheric coherence. eLORETA analysis identified sources of alpha1 activity in midline cortical regions that overlapped with the DMN. Greater activation in areas that overlap the DMN during TM practice suggests that meditation practice may lead to a foundational or ‘ground’ state of cerebral functioning that may underlie eyes-closed rest and more focused cognitive processes.     

Kinesthetic Cues in the Development of Time Concepts

The intent of this study was to document general behavioral correlates of cognitive impulsivity. Fourth-grade children were individually administered the Matching Familiar Figures (MFF) test, and the resulting measures (latency and errors) were correlated with a group administered scale of impulsivity, the Impulsivity Scale for Children (ISC) and eight teacher ratings evaluating the child on a series of different behaviors. No relationships existed between MFF measures and the ISC; and only one teacher rating correlated significantly with either MFF variable. This teacher rating (tendency to respond) was found to be the only discriminating teacher rating, and the high correlation between it and the MFF latency was explained because of the high task similarity between MFF requirements and the behaviors rated on “tendency to respond.” Cognitive impulsivity was not predicted by classroom behavior, implying that an individual's preferred conceptual tempo is not a part of a global impulsive behavior pattern but rather a relatively independent dimension of cognitive style. The questionable validity of the ISC was discussed for children of this age group, as was the significant correlation between Primary Mental Abilities (PMA) scores and the ISC scores.     

Neurocognitive Sequelae of Pediatric Sickle Cell Disease: A Review of the Literature

This literature review summarizes all studies relating neuropsychological performance to neuroimaging findings in pediatric sickle cell disease (N=28; published 1991–2005). Although inconsistencies exist within and across domains, deficits in intelligence (IQ), attention and executive functions, memory, language, visuomotor abilities, and academic achievement have been identified. Overall neurocognitive compromise was revealed to be related to the level of neurological injury and the location of silent infarct. Attentional and executive dysfunction is prevalent and related to frontal lobe abnormalities.     

Note of Correction for Schwartz,Cohen and Pavlik's “The Effects of Subject-and Experimenter-Induced Defensive Response Sets on Picture-Frustration Test Reactions”

The multiple-choice version of the Rosenzweig P-F Study and the use of projection slides in group administration restrict the full diagnostic potential of the instrument. Moreover, these unauthorized modifications represent infringements of copyright. These variants are therefore not available for future use or imitation.     

Revised Criteria for the Group Conformity Rating of the Rosenzweig Picture-Frustration Study,Adult Form

Summary

Revised criteria for the Group Conformity Rating (GCR) of the Rosenzweig Picture-Frustration Study, Adult Form, are presented on the basis of findings from a population of 460 subjects. These criteria supersede the earlier ones based on a minimal sample of 100 subjects. The method of establishing the GCR criteria is described in detail. A comparison of GCR scores yielded by the original and the revised criteria for two samples of subjects indicates that, though the revised criteria are more complete and more stable and should supersede the earlier ones, results previously obtained with the original criteria are not invalid.
