FDG-PET Analysis and Findings in Amnesia Resulting From Hypoxia

The assumptions underlying neuroimaging, and problems in its analysis and interpretation, are commonly underestimated in neuropsychology. The ways in which fluoro-deoxy-glucose (FDG) positron emission tomography (PET) data can be analysed are discussed. PET findings from four patients who had suffered severe amnesia, following episodes of acute hypoxia, are presented. These patients had shown evidence of medial temporal (hippocampal and parahippocampal) atrophy on MRI brain scans. The PET data were analysed in several different ways. The converging findings were that the patients showed bilateral thalamic hypometabolism, and there was also evidence of retrosplenial hypometabolism bilaterally. Cognitively, these patients performed most like other patients with medial temporal lesions, but the results indicate that structural lesions can have distal metabolic effects on structures elsewhere. These findings are interpreted in the light of neuroanatomical observations concerning parallel projections between medial temporal lobe structures and the thalamus, some of which pass via the retrosplenium.     

Aesthetic Judgment and Perceptual Normativity

I draw a connection between the question, raised by Hume and Kant, of how aesthetic judgments can claim universal agreement, and the question, raised in recent discussions of nonconceptual content, of how concepts can be acquired on the basis of experience. Developing an idea suggested by Kant's linkage of aesthetic judgment with the capacity for empirical conceptualization, I propose that both questions can be resolved by appealing to the idea of “perceptual normativity”. Perceptual experience, on this proposal, involves the awareness of its own appropriateness with respect to the object perceived, where this appropriateness is more primitive than truth or veridicality. This means that a subject can take herself to be perceiving an object as she (and anyone else) ought to perceive it, without first recognizing the object as falling under a corresponding concept. I motivate the proposal through a criticism of Peacocke's account of concept‐acquisition, which, I argue, rests on a confusion between the notion of a way something is perceived, and that of a way it is perceived as being. Whereas Peacocke's account of concept‐acquisition depends on an illicit slide between these two notions, the notion of perceptual normativity allows a legitimate transition between them: if someone's perceiving something a certain way involves her taking it that she ought to perceive it that way, then she perceives the thing as being a certain way, so that the corresponding concept is available to her in perceptual experience.     

Aesthetic Judging and The Intentionality of Pleasure

I point out some unclarities in Allison's interpretation of Kant's aesthetic theory, specifically in his account of the free play of the faculties. I argue that there is a tension between Allison's commitment to the intentionality of the pleasure involved in a judgment of beauty, and his view that the pleasure is distinct from the judgment, and I claim that the tension should be resolved by rejecting the latter view. I conclude by addressing Allison's objection that my own view fails to accommodate judgments of non-beauty or ugliness.     

Linking Religion and Spirituality with Psychological Well-being: Examining Self-actualisation, Meaning in Life, and Personal Growth Initiative

Research largely shows that religion and spirituality have a positive correlation to psychological well-being. However, there has been a great deal of confusion and debate over their operational definitions. This study attempted to delineate the two constructs and categorise participants into different groups based on measured levels of religious involvement and spirituality. The groups were then scored against specific measures of well-being. A total of 205 participants from a wide range of religious affiliations and faith groups were recruited from various religious institutions and spiritual meetings. They were assigned to one of four groups with the following characteristics: (1) a high level of religious involvement and spirituality, (2) a low level of religious involvement with a high level of spirituality, (3) a high level of religious involvement with a low level of spirituality, and (4) a low level of religious involvement and spirituality. Multiple comparisons were made between the groups on three measures of psychological well-being: levels of self-actualisation, meaning in life, and personal growth initiative. As predicted, it was discovered that, aside from a few exceptions, groups (1) and (2) obtained higher scores on all three measures. As such, these results confirm the importance of spirituality on psychological well-being, regardless of whether it is experienced through religious participation.     

The Home-Based Occupational Therapy Intervention in the Alzheimer's Disease Multiple Intervention Trial (ADMIT)

There is no way to prevent functional declines related to Alzheimer's Disease (AD). The use of occupational therapy (OT) has been shown to be successful in managing some aspects of AD. We added home-based OT to evidence-based best practice for AD with the aim of delaying functional decline in people with AD. OT was delivered in the home to a caregiver dyad including the person with AD and her/his caregiver. This article describes the OT intervention for the AD Multiple Intervention Trial, a parallel randomized controlled trial. We include baseline data on the 180 caregiver dyads.     

Toward Modeling and Automating Ethical Decision Making: Design, Implementation, Limitations, and Responsibilities

One recent priority of the U.S. government is developing autonomous robotic systems. The U.S. Army has funded research to design a metric of evil to support military commanders with ethical decision-making and, in the future, allow robotic military systems to make autonomous ethical judgments. We use this particular project as a case study for efforts that seek to frame morality in quantitative terms. We report preliminary results from this research, describing the assumptions and limitations of a program that assesses the relative evil of two courses of action. We compare this program to other attempts to simulate ethical decision-making, assess possibilities for overcoming the trade-off between input simplification and output reliability, and discuss the responsibilities of users and designers in implementing such programs. We conclude by discussing the implications that this project highlights for the successes and challenges of developing automated mechanisms for ethical decision making.     

Opposite effects of anxiety and depressive symptoms on executive function: The case of selecting among competing options

People constantly face the need to choose one option from among many, such as when selecting words to express a thought. Selecting between many options can be difficult for anyone, and can feel overwhelming for individuals with elevated anxiety. The current study demonstrates that anxiety is associated with impaired selection across three different verbal tasks, and tests the specificity of this finding to anxiety. Anxiety and depression frequently co-occur; thus, it might be assumed that they would demonstrate similar associations with selection, although they also have distinct profiles of symptoms, neuroanatomy and neurochemistry. Here, we report for the first time that anxiety and depressive symptoms counter-intuitively have opposite effects on selection among competing options. Specifically, whereas anxiety symptoms are associated with impairments in verbal selection, depressive symptoms are associated with better selection performance. Implications for understanding the mechanisms of anxiety, depression and selection are discussed.     

Rates of Subthreshold PTSD Among U.S. Military Veterans and Service Members: A Literature Review

The current study’s goal was to provide a comprehensive review of current subthreshold posttraumatic stress disorder (PTSD) rates among U.S. military veterans and service members. PubMed, PsycInfo, ProQuest, Web of Knowledge, Google Scholar, and any relevant articles’ reference lists identified studies of subthreshold PTSD in the U.S. military. Search terms included PTSD in combination with partial, subthreshold or sub-threshold, subsyndromal or sub-syndromal, subclinical or sub-clinical, and military or veteran. Sixteen articles met criteria for review. Current subthreshold PTSD rates ranged from 2.3% to 22.3%, with a weighted mean rate of 7.6%. Definitional variation within and across the “below threshold” terms produced some variability in rates reported. Few studies consistently reported on impairment and comorbidity in the subthreshold PTSD population. Variability of current subthreshold PTSD rates may be due to methodological issues such as sampling methods, sample sizes, and how below threshold PTSD was assessed and defined. Based on our findings, we provide a number of recommendations that can be used to inform future research of subthreshold PTSD among U.S. military veterans and service members. These recommendations include having a standardized term and definition, determining how to more properly assess subthreshold PTSD symptomatology, clarifying subthreshold PTSD diagnostic stability, and identifying appropriate sampling methods.     

Signs of Resistance: Peer Learning of Sign Languages Within ‘Oral’ Schools for the Deaf

This article explores the role of the Deaf child as peer educator. In schools where sign languages were banned, Deaf children became the educators of their Deaf peers in a number of contexts worldwide. This paper analyses how this peer education of sign language worked in context by drawing on two examples from boarding schools for the deaf in Nicaragua and Thailand. The argument is advanced that these practices constituted a child-led oppositional pedagogy. A connection is drawn to Freire’s (1972) theory of critical pedagogy. Deaf children’s actions as peer educators are framed as an act of resistance towards the oppression of their language and culture. A contrast is drawn between oralist pedagogy that is historically associated with punitive practices and didactic methods and the experiential and dialogic interaction that characterised peer learning of sign languages. The argument is made that the peer teaching and learning processes enabled the self-actualisation of the Deaf children whereas the oralist methods were based on a deficit model that focused on modifying deaf children according to the norms of hearing society. The implications of this for current policy and practice are inferred to be about access to sign languages and the importance of Deaf communities in deaf children’s education. The argument is made that space needs to be created for deaf children to engage in peer learning.
