Unanswerable questions for everyone: reply to Inan

Millianism is the familiar view that some expressions, such as proper names, contribute only their referent to the semantic content of sentences in which they occur. Inan (Philosophical Studies 2010) has recently argued that the Millian is committed to the following odd conclusion: There may be questions that he is able to grasp but that he cannot answer, either affirmatively, negatively, or with a simple ??I don??t know??. The Millian is indeed committed to this conclusion. But we intend to show that Inan??s argument generalizes, so that everyone who accepts certain largely uncontroversial principles is committed to the odd conclusion that there may be questions that are graspable but not answerable.     

How to refrain from answering Kripke’s puzzle

In this paper, I investigate the prospects for using the distinction between rejection and denial to resolve Saul Kripke??s puzzle about belief. One puzzle Kripke presents in ??A Puzzle About Belief?? poses what would have seemed a fairly straightforward question about the beliefs of the bilingual Pierre, who is disposed to sincerely and reflectively assent to the French sentence ??Londres est jolie??, but not to the English sentence ??London is pretty??, both of which he understands perfectly well. The question to be answered is whether Pierre believes that London is pretty, and Kripke argues, of each answer, that it is unacceptable. On my proposal, either answer to the question is to be rejected, but neither answer is to be denied, using the resource of partially-defined predicates. After demonstrating how this serves as a solution to the puzzle, I illustrate some philosophical motivations??independent of Kripke??s puzzle??for adopting a view on which belief is a partially defined predicate. I conclude that there are decent prospects for the proposed response to Kripke??s puzzle.     

Psychology of Conversion and Spiritual Transformation

This article provides an overview of the four major psychological approaches used in the study of religious change. A heuristic stage model of conversion consisting of seven stages: context, crisis, quest, encounter, interaction, commitment, and consequences (Rambo 1995) serves as a framework for integrating the research of these four approaches, providing a fuller understanding of the multilayered processes involved in conversion. The authors hope that the phenomenon of spiritual transformation and conversion will continue to draw the attention of psychologists who increasingly appreciate the complexity and dynamism of religious/spiritual transformation. For the psychology of religion in general and the psychology of conversion and spiritual transformation in particular to be viable and valuable, psychologists will need to join with researchers in the human sciences and religious studies to develop methods and theories worthy of this complex subject. Additionally, through collaboration with psychologists in the People’s Republic of China, the authors look forward to exploring together the fascinating and important issues that emerge as we seek to understand the nature of conversion and spiritual transformation in China.     

Developing a Prevention Synthesis and Translation System to Promote Science‐Based Approaches to Teen Pregnancy,HIV and STI Prevention

The Interactive Systems Framework for Dissemination and Implementation (ISF) is a multi‐system framework that can guide research‐to‐practice efforts by building and supporting the work of three interacting systems: the Prevention Delivery, Support, and Synthesis and Translation Systems. The Synthesis and Translation system is vital to bridging science and practice, yet how to develop it and train support system partners to use it is under‐researched. This article bridges this gap by offering a case example of the planning, development, and use of a synthesis and translation product called Promoting Science‐based Approaches to Teen Pregnancy Prevention using Getting To Outcomes. The case presented documents the process used for developing the synthesis and translation product, reports on efforts to engage the Prevention Support system to use the product, and how we approached building interaction between the Synthesis and Translation System and the Support System partners. Practice‐oriented evaluation data are also presented. Implications for practice, policy and research are discussed.

Understanding emotion: lessons from anxiety

We agree that conceptualisation is key in understanding the brain basis of emotion. We argue that by conflating facial emotion recognition with subjective emotion experience, Lindquist et al. understate the importance of biological predisposition in emotion. We use examples from the anxiety disorders to illustrate the distinction between these two phenomena, emphasising the importance of both emotional hardware and contextual learning.     

Local dynamic stability of trunk movements during the repetitive lifting of loads

The local dynamic stability of trunk movements was assessed during repetitive lifting using nonlinear Lyapunov analyses. The goal was to assess how varying the load-in-hands affects the neuromuscular control of lumbar spinal stability. Thirty healthy participants (15M, 15F) performed repetitive lifting at 10 cycles per minute for three minutes under two load conditions: zero load and 10% of each participant's maximum back strength. Short- and long-term maximum finite-time Lyapunov exponents (λ(max-s) and λ(max-l)), describing responses to infinitesimally small perturbations, were calculated from the measured trunk kinematics to estimate the local dynamic stability of the system. Kinematic variability was also assessed using mean standard deviations (MeanSD) across cycles. The results of a mixed-design repeated-measures ANOVA showed that increasing the load lifted significantly reduced λ(max-s) (μ(0%-LOAD)=0.379, μ(10%-LOAD)=0.335, p<.001), but not λ(max-l) (μ(0%-LOAD)=0.46E-03, μ(10%-LOAD)=2.41E-03, p=.055) or MeanSD (μ(0%-LOAD)=2.57, μ(10%-LOAD)=2.89, p=.164). There were no between-subject effects of sex, or significant interactions (α<.05). The present findings indicated improved dynamic spinal stability when lifting the heavier load; meaning that as muscular and moment demands increased, so too did participants' abilities to respond to local perturbations. These results support the notion of greater spinal instability during movement with low loads due to decreased muscular demand and trunk stiffness, and should aid in understanding how lifting various loads contributes to occupational low back pain.     

Development of an Evidence-Based Information Booklet to Support Parents of Children Without a Diagnosis

The aim of this study was to develop an evidence-based psychosocial information booklet for parents of children without a specific diagnosis, many of whom are seen through the genetic clinic. A mixed methods approach was adopted involving four phases. The first two phases involving a systematic review and in-depth interviews are summarised briefly but reported in detail elsewhere. Phase 3 comprised: (1) a grey literature search to identify relevant literature and resources from other patient organizations; (2) drafting the booklet using themes identified through the previous phases; (3) piloting the booklet with eight professional and support group stakeholders and (4) piloting the booklet with 14 parents (from Phase 2) to ensure the information reflected their experiences. In Phase 4, we assessed satisfaction with the booklet through a questionnaire completed by 38 parents. The booklet was well accepted. The importance of providing the booklet at the beginning of the parental ‘journey’ was identified. We have developed an evidence-based information booklet to support parents via a rigorous mixed methods approach. This booklet meets a largely unmet psychosocial need and could be used in practice to support parents of children without a diagnosis.     

Dorsal striatal dopamine depletion impairs both allocentric and egocentric navigation in rats

Successful navigation requires interactions among multiple but overlapping neural pathways mediating distinct capabilities, including egocentric (self-oriented, route-based) and allocentric (spatial, map-based) learning. Route-based navigation has been shown to be impaired following acute exposure to the dopaminergic (DA) drugs (+)-methamphetamine and (+)-amphetamine, but not the serotoninergic (5-HT) drugs (±)-3,4-methylenedioxymethamphetamine or (±)-fenfluramine. The dopaminergic-rich neostriatum is involved in both allocentric and egocentric navigation. This experiment tested whether dorsal striatal DA loss using bilateral 6-hydroxydopamine (6-OHDA) injections impaired one or both types of navigation. Two weeks following 6-OHDA injections, rats began testing in the Cincinnati water maze (CWM) followed by the Morris water maze (MWM) for route-based and spatial navigation, respectively. 6-OHDA treatment significantly increased latency and errors in the CWM and path length, latency, and cumulative distance in the MWM with no difference on cued MWM trials. Neostriatal DA levels were reduced by 80% at 2 and 7 weeks post-treatment. In addition, 6-OHDA increased DA turnover and decreased norepinephrine (NE) levels. 6-OHDA injections did not alter monoamine levels in the prefrontal cortex. The data support that neostriatal DA modulates both types of navigation.     

"When the age is in, the wit is out": Age-related self-categorization and deficit expectations reduce performance on clinical tests used in dementia assessment

This study examined the combined effects of age-based self-categorization and aging expectations on cognitive performance in a clinical context. An experimental study manipulated older adults' salient self-categorization as Younger or Older, as well as expectations that aging involves a specific memory decline versus generalized cognitive decline. Memory and general ability tests that are typically used in dementia screening were then administered. As predicted, self-categorization as Older dramatically reduced performance, but the measure on which this effect was revealed depended on aging expectations. Participants who self-categorized as Older and expected memory to decline performed worse on memory tests. Conversely, participants who self-categorized as Older and expected widespread cognitive decline performed worse on the general ability test. The clinical implications for the latter group were profound, because 70% met the diagnostic criterion for dementia, compared with an average of 14% in other conditions. The importance of self-categorization processes when interpreting performance on tests used to diagnose dementia are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Health Dynamics of Military and Veteran Couples: A Biopsychorelational Overview

The purpose of this review article is to present the current state of military and veteran couple??s health by addressing biological, psychological, and relational risks and resiliencies. Articles were selected using key words such as ??military couple, dyad, or relationship?? and were searched in the following databases: PsychInfo, Military and Government Collection, and Medline. Literature trends reveal that the role of the military spouse is no longer secondary, but is crucial to the health of the military and veteran couple. The spouse is recommended to be a part of the biopsychosocial assessment that service members receive and also be assessed themselves for stress derived symptoms such as hypertension, post traumatic stress, and depression. Assessments for health should occur sooner after deployment and at more frequent intervals given the dynamic nature of stress on health over time. The health of service members and veterans is couched within their personal and familial relationships, thus medical family therapists are the most well prepared to attend to the dynamics between health, stress, and relational well-being across the lifespan of military and veteran couples.
