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.     

Problem–solving conversations in marriage: Does it matter what topics couples discuss?

To address the validity of a common procedure for assessing problem–solving communication behavior in marriage, this study investigated the extent to which communication behavior is influenced by the difficulty of the topic being discussed. Married couples engaged in a sequence of four videotaped problem–solving conversations, and the topics discussed in each conversation were coded for difficulty. Hierarchical linear modeling was used to investigate both proximal and distal influences on communication behavior. At the proximal level, couples did not change their communication behavior in response to changes in topic difficulty that occurred across the four conversations. At the distal level, couples experiencing conflict over a highly difficult topic reported low relationship satisfaction and used negative forms of communication behavior in all their problem–solving conversations, regardless of the issue being discussed. The relationship between topic difficulty and communication behavior was mediated by marital satisfaction.     

Time is tight: how higher economic value of time increases feelings of time pressure

The common heuristic association between scarcity and value implies that more valuable things appear scarcer (King, Hicks, & Abdelkhalik, 2009), an effect we show applies to time as well. In a series of studies, we found that both income and wealth, which affect the economic value of time, influence perceived time pressure. Study 1 found that changes in income were associated with changes in perceived time pressure. Studies 2-4 showed that experimentally manipulating time's perceived economic value caused greater feelings of time pressure and less patient behavior. Finally, Study 5 demonstrated that the relationship between income and time pressure was strengthened when participants were randomly assigned to think about the precise economic value of their time.
