Neuronal correlates of "free will" are associated with regional specialization in the human intrinsic/default network

Recently, we proposed a fundamental subdivision of the human cortex into two complementary networks-an "extrinsic" one which deals with the external environment, and an "intrinsic" one which largely overlaps with the "default mode" system, and deals with internally oriented and endogenous mental processes. Here we tested this hypothesis by contrasting decision making under external and internally-derived conditions. Subjects were presented with an external cue, and were required to either follow an external instruction ("determined" condition) or to ignore it and follow a voluntary decision process ("free-will" condition). Our results show that a well defined component of the intrinsic system-the right inferior parietal cortex-was preferentially activated during the "free-will" condition. Importantly, this activity was significantly higher than the base-line resting state. The results support a self-related role for the intrinsic system and provide clear evidence for both hemispheric and regional specialization in the human intrinsic system.     

Monitoring and Anti-Reductionism in the Epistemology of Testimony

One of the central points of contention in the epistemology of testimony concerns the uniqueness (or not) of the justification of beliefs formed through testimony–whether such justification can be accounted for in terms of, or 'reduced to', other familiar sort of justification, e.g. without relying on any epistemic principles unique to testimony. One influential argument for the reductionist position, found in the work of Elizabeth Fricker, argues by appeal to the need for the hearer to monitor the testimony for credibility. Fricker (1994) argues, first, that some monitoring for trustworthiness is required if the hearer is to avoid being gullible, and second, that reductionism but not anti-reductionism is compatible with ascribing an important role to the process of monitoring in the course of justifiably accepting observed testimony. In this paper we argue that such an argument fails.     

Cognitive Coping Tool Kit for Psychosis: Development of a Group-Based Curriculum

This article outlines an 8-week curriculum that was created to help outpatients develop cognitive and behavioral skills for coping with delusions and hallucinations as well as to reduce patients’ comorbid subjective levels of distress (e.g., depression, anxiety). The manualized protocol consisted of psychoeducation and training in a variety of CBT skills that have shown promise in treating individuals with residual psychosis, using recovery-oriented “naturalistic” methods and culminating in the creation of an individualized “tool kit” of cognitive coping resources. A preliminary study of the effectiveness of this brief group-based CBT program for outpatients with chronic, residual symptoms of schizophrenia was conducted. Participants were 24 outpatients diagnosed with schizophrenia spectrum disorders who were stable on medications and connected to case management community follow-up. The Positive and Negative Syndrome Scale for Schizophrenia interview and the Symptom Checklist-90 self-report symptom scales were administered pre- and post-intervention. The results suggest that there were significant improvements in psychotic symptoms and self-reported distress from pre- to posttreatment.     

The role of spatial location in remembering and forgetting peripheral words.

This study examined whether spatial location mediates intentional forgetting of peripherally presented words. Using an item-method directed forgetting paradigm, words were presented in peripheral locations at study. A recognition test presented all words at either the same or a different location relative to study. Results showed that while recognition of Remember words was unaffected by test location, when Forget words were presented in the same location at test as at study, recognition accuracy was significantly greater than when presented in a different location. Experiment 2 showed that the speed to localize a previously studied word was faster when it was presented in the same rather than a different study-test location but that the magnitude of this spatial priming was unaffected by memory instruction. We suggest that the location of peripherally presented words is represented in memory and can aid the retrieval of poorly encoded words.     

Developmental "Roots" in Mature Biological Knowledge

ABSTRACT— Young children tend to claim that moving artifacts and nonliving natural kinds are alive, but neglect to ascribe life to plants. This research tested whether adults exhibit similar confusions when verifying life status in a speeded classification task. Experiment 1 showed that undergraduates encounter greater difficulty (reduced accuracy and increased response times) in determining life status for plants, relative to animals, and for natural and moving nonliving things, relative to artifacts and nonmoving things. Experiment 2 replicated these effects in university biology professors. The professors showed a significantly reduced effect size for living things, as compared with the students, but still showed greater difficulty for plants than animals, even as no differences from the students were apparent in their responses to nonliving things. These results suggest that mature biological knowledge relies on a developmental foundation that is not radically overwritten or erased with the profound conceptual changes that accompany mastery of the domain.     

Triangulation,Untranslatability, and Reconciliation

Donald Davidson used triangulation to do everything from explicate psychological and semantic externalism, to attack relativism and skepticism, to propose conditions necessary for thought and talk. At one point Davidson tried to bring order to these remarks by identifying three kinds of triangulation, each operative in a different situation. Here I take seriously Davidson’s talk of triangular situations and extend it. I start by describing Davidson’s situations. Next I establish the surprising result that considerations from one situation entail the possibility that at any one time one language is partially untranslatable into another. Because the possibility is time-indexed, it need not conflict with Davidson’s own argument against the possibility of untranslatability. I derive the result, not to indict Davidson, but to propose a new kind of triangulation, the reconciliation of untranslatability, which I investigate. Insofar as triangulation is central to Davidson’s views, getting a handle on his various triangular situations is key to getting a handle on his contributions to philosophy. Insofar as those contributions have enriched our understanding of how language, thought, and reality interrelate, extending Davidson’s model promises to extend our understanding too.

Learning to sleep through the night: Solution or strain for mothers and young children?

Is the process of helping infants and young children learn to sleep through the night a solution to family sleep problems or does it exacerbate matters for mother and child? Retrospective and current accounts from a nonclinical, convenience sample of 102 mothers of preschool‐aged children provided information on sleep issues from early infancy through preschool age. Child, mother, and parenting characteristics, along with family sleep arrangements, were differentially related to the age at which children learned to sleep through the night and to the extent of difficulty that characterized this experience. Mothers who indicated more difficulty as their children learned to sleep through the night also reported more depressive symptoms and more strain in the mother–child relationship. Later age at sleeping through the night was more common among early bedsharers, but timing of sleeping through the night was not associated with preschool children's reported independence in several nonsleep domains. Sleep arrangements and the importance placed on sleeping through the night were the strongest contributors to variance explained in whether children learned to sleep through the night during infancy or toddlerhood. When advising parents about sleep interventions, practitioners should seek to understand whether families' parenting values fit their nighttime sleep practices.     

Consumer decision making and aging: A commentary from a public policy/marketing perspective

Efforts to assist older adults with cognitive deficits can take one of three paths: law, education or marketing. Legal protections have proved insufficient. Government educational efforts are typically dryly factual and likely to go unheeded. With the growing size of the older adult market, the independent efforts of both for-profit and social marketers to develop products and services that can help this population remain functionally healthy and independent are likely to be successful. Both governments and insurance companies should be motivated to help subsidize these entrepreneurial efforts given the considerably higher costs of caring for the elderly in an institution.     

Psychologist as Mentor and Detective in the Mirror of the Soul

A case study is presented of a client, involved in business dealings and personal relationships with members of organized crime, who upon looking into his mirror one morning recognized for the first time that his life was quickly slipping away. Unless he broke free, he decided, by doing something bold and outrageous—in the style of his free-spirited and violent youth—he was doomed to a depressive existence for the remainder of his days. He stalked women by night. Disturbed by a series of frightening dreams of his involvement in the murder of a stalked and raped woman, he approached the author for psychological help. During the course of treatment it became apparent that the client lacked a sense of personal goodness. An exploration of the problematic nature of virtue and constructive behavior in psychotherapeutic theory is presented here, together with a rationale for the role of the therapist as mentor as well as therapist for people who lack early and present experiences with constructive role models.
