Defending the Possibility of Knowledge

In this paper, I propose a solution to Fitch’s paradox that draws on ideas from Edgington (Mind 94:557–568, 1985), Rabinowicz and Segerberg (1994) and Kvanvig (Noûs 29:481–500, 1995). After examining the solution strategies of these authors, I will defend the view, initially proposed by Kvanvig, according to which the derivation of the paradox violates a crucial constraint on quantifier instantiation. The constraint states that non-rigid expressions cannot be substituted into modal positions. We will introduce a slightly modified syntax and semantics that will help underline this point. Furthermore, we will prove results about the consistency of verificationism and the principle of non-omniscience by model-theoretical means. Namely, we prove there exists a model of these principles, and delineate certain constraints they pose on a structure in which they are true.     

Recognition by association: Within‐ and cross‐modality associative priming with faces and voices

Recent literature has raised the suggestion that voice recognition runs in parallel to face recognition. As a result, a prediction can be made that voices should prime faces and faces should prime voices. A traditional associative priming paradigm was used in two studies to explore within‐modality priming and cross‐modality priming. In the within‐modality condition where both prime and target were faces, analysis indicated the expected associative priming effect: The familiarity decision to the second target celebrity was made more quickly if preceded by a semantically related prime celebrity, than if preceded by an unrelated prime celebrity. In the cross‐modality condition, where a voice prime preceded a face target, analysis indicated no associative priming when a 3‐s stimulus onset asynchrony (SOA) was used. However, when a relatively longer SOA was used, providing time for robust recognition of the prime, significant cross‐modality priming emerged. These data are explored within the context of a unified account of face and voice recognition, which recognizes weaker voice processing than face processing.     

Keeping (Direct) Reference in Mind

This paper explores the psychological analogues of a cluster of arguments that have played an important role in motivating a now widespread, reference‐based approach in philosophy of language. What I will call the psychological analogues of Kripke‐style arguments provide a substantial motivation for a reference‐based approach to concepts. Insofar as such an approach is rarely given serious consideration, the availability of these arguments suggests the need for a rethinking of some foundational assumptions in philosophy of mind and other branches of the cognitive sciences.     

Online Advertisements and Conceptual Implicit Memory: Advances in Theory and Methodology

We conducted three experiments to further our understanding, both theoretically and methodologically, of conceptual implicit memory within the advertising context. Results from the first experiment confirmed what previous research had suggested: using a brand generation task is a conceptual implicit memory measure. The first experiment also demonstrated that conceptual priming can be found using realistic‐looking advertisements embedded within a news website. Results from Experiments 2 and 3 suggest that not only is providing specific encoding instructions not necessary to induce conceptual or semantic processing but also that there were no differences based on whether the experimental procedure was conducted in a laboratory or online. Together, these results have implications for increasing the ecological validity of this type of research. By allowing participants to view realistic advertisements outside of a laboratory without specific encoding instructions, the procedure much more closely mimics how individuals actually interact with advertisements in real life.

A Clinical Intervention in Chronic Pain and Insomnia with a Combined Model of Treatment: A Test of Concept

Co-occurring chronic pain and insomnia are common in a clinical setting. Cognitive–behavioral theoretical (CBT) frameworks exist for both conditions independently. The purpose of this study was to address the problem of co-occurring chronic pain and insomnia with an integrated CBT model based on empirical support. One-hundred eleven individuals (age range 21–65 years) meeting the general criteria for chronic pain and insomnia were included in this study. Participants completed a demographic form, the Dysfunctional Beliefs and Attitudes about Sleep—16-item version, Insomnia Severity Index, Sleep Hygiene Index, Sleep Associated Monitoring Index, Pain Catastrophizing Scale, Pain Disability Questionnaire, Modified Somatic Perceptions Questionnaire, Hospital Anxiety and Depression Scale, and Multidimensional Scale of Perceived Social Support. Significant positive bivariate relationships were observed for pain catastrophizing (PC) and dysfunctional beliefs and attitudes about sleep (DBAS), as well as somatic awareness and sleep-associated monitoring. Two backward stepwise regression models were utilized to determine a model for predicting insomnia severity and pain disability respectively using a combination of sleep and pain-associated measures. Insomnia severity was predicted by DBAS, PC, and somatic awareness. Pain disability was predicted by PC, DBAS, depression, and social support. Maladaptive thought patterns related to pain and insomnia and associated features appear to have a synergistic effect on both insomnia severity and pain disability and support a combined cognitive–behavioral model.     

Psychopaths and blame: The argument from content

The recent debate over the moral responsibility of psychopaths has centered on whether, or in what sense, they understand moral requirements. In this paper, I argue that even if they do understand what morality requires, the content of their actions is not of the right kind to justify full-blown blame. I advance two independent justifications of this claim. First, I argue that if the psychopath comes to know what morality requires via a route that does not involve a proper appreciation of what it means to cause another harm or distress, the content of violations of rules against harm will be of a lower grade than the content of similar actions by normal individuals. Second, I argue that in order to intend a harm to a person—that is, to intend the distinctive kind of harm that can only befall a person—it is necessary to understand what personhood is and what makes it valuable. The psychopath's deficits with regard to mental time travel ensure that s/he cannot intend this kind of harm.     

HIV infection in the South African construction industry

South Africa has one of the highest HIV prevalences in the world, and compared with other sectors of the national economy, the construction industry is disproportionately adversely affected. Using data collected nationally from more than 57,000 construction workers, HIV infection among South African construction workers was estimated, together with an assessment of the association between worker HIV serostatus and worker characteristics of gender, age, nature of employment, occupation, and HIV testing history. The HIV infection of construction workers was estimated to be lower than that found in a smaller 2008 sample. All worker characteristics are significantly associated with HIV serostatus. In terms of most at-risk categories: females are more at risk of HIV infection than males; workers in the 30–49 year old age group are more at risk than other age groups; workers employed on a less permanent basis are more at risk; as are workers not having recently tested for HIV. Among occupations in the construction industry, general workers, artisans, and operator/drivers are those most at risk. Besides yielding more up-to-date estimated infection statistics, this research also identifies vulnerable sub-groups as valuable pointers for more targeted workplace interventions by construction firms.     

School Perceptions of Children Raised by Grandparents

Increasing numbers of children raised by grandparents are students in schools. Their substitute family structure and precursors to the emergence of this family structure have implications for the children's school performance. Research suggests teachers view these children as at risk for difficult school functioning. The aforementioned judgment is problematic because teacher expectations, attributions, and biases are associated with stereotype threat that impacts student performance adversely. The author compares children raised by grandparents with children raised by parents and foster parents. The author examines the children's perceptions of their teachers' views of their school performance. He also examines the children's general feelings about school. Participants in the study were 6,550 students in Grades 6–8 from the nationally representative Health Behaviour in School-aged Children survey. Nonparametric statistical analyses reveal children raised by grandparents believe teachers' view their school performance negatively when compared with children living with both parents. Strategies are described to improve the children's performance in school and to foster favorable teacher perceptions.     

Nation,Narration, and Health in Mohamedou Ould Slahi’s <Emphasis Type="Italic">Guantánamo Diary</Emphasis>

Scholars have mostly analyzed information from mental health practitioners, attorneys, and institutions to critique mental health practices in the War on Terror. These sources offer limited insights into the suffering of detainees. Detainee accounts provide novel information based on their experiences at Guantánamo. Mohamedou Ould Slahi’s Guantánamo Diary is the only text from a current detainee that provides a first-person account of his interrogations and interactions with health professionals. Despite being advertised as a diary, however, it has undergone redaction from American government officials. This article examines Slahi’s account of his interrogations and representations of mental health at Guantánamo and considers its role within the narrative function of the nation. At stake is the right of detainees to narrate, scholars to critique medical practices in the War on Terror, and the nation’s attempts to control its narration.
