Are there unconscious perceptual processes?

Blindsight and vision for action seem to be exemplars of unconscious visual processes. However, researchers have recently argued that blindsight is not really a kind of unconscious vision but is rather severely degraded conscious vision. Morten Overgaard and colleagues have recently developed new methods for measuring the visibility of visual stimuli. Studies using these methods show that reported clarity of visual stimuli correlates with accuracy in both normal individuals and blindsight patients. Vision for action has also come under scrutiny. Recent findings seem to show that information processed by the dorsal stream for online action contributes to visual awareness. Some interpret these results as showing that some dorsal stream processes are conscious visual processes (e.g., Gallese, 2007; Jacob & Jeannerod, 2003). The aim of this paper is to provide new support for the more traditional view that blindsight and vision for action are genuinely unconscious perceptual processes. I argue that individuals with blindsight do not have access to the kind of purely qualitative color and size information which normal individuals do. So, even though people with blindsight have a kind of cognitive consciousness, visual information processing in blindsight patients is not associated with a distinctly visual phenomenology. I argue further that while dorsal stream processing seems to contribute to visual awareness, only information processed by the early dorsal stream (V1, V2, and V3) is broadcast to working memory. Information processed by later parts of the dorsal stream (the parietal lobe) never reaches working memory and hence does not correlate with phenomenal awareness. I conclude that both blindsight and vision for action are genuinely unconscious visual processes.     

Moral Relativism and Moral Expressivism

Though moral relativism has had its supporters over the years, it is not a dominant position in philosophy. I will argue here, though, that the view is an attractive position. It evades some hardcore challenges that face absolutism, and it is reconcilable with an appealing emotivist approach to moral attitudes. In previous work, I have offered considerations in favor of a version of moral relativism that I call “perspectivalism.” These considerations are primarily grounded in linguistic data. Here I offer a self‐standing argument for perspectivalism. I begin with an argument against moral absolutism. I then argue that moral terms, such as ‘wrong’ and ‘right’, require for their application that the moral judge instantiate particular affective states, and I use this claim to provide further defense of moral relativism.     

Memory in Early Onset Bipolar Disorder and Attention-Deficit/Hyperactivity Disorder: Similarities and Differences

Differentiating between early-onset bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD) can be difficult. Memory problems are commonly reported in BD, and forgetfulness is among the diagnostic criteria for ADHD. We compared children and adolescents with BD (n?=?23), ADHD combined type (ADHD-C; n?=?26), BD?+?ADHD-C (n?=?15), and 68 healthy controls on memory tests (Digit span, Children's Verbal Learning Test-II). Further analyses were performed on subgroups of BD (BD-I, BD-II/BD-NOS, with and without previous psychotic symptoms). All clinical groups demonstrated some problems with free recall, but the BD subgroup with a history of psychotic symptoms had a more pervasive problem that also included recognition and semantic clustering. The ADHD-C groups demonstrated the lowest performance on working memory. These data suggest that children and adolescents with BD and previously psychotic symptoms may have inefficient encoding of verbal material, whereas memory problems in ADHD-C appear more characterized by impaired free recall.     

Predictors of Heart-Focused Anxiety in Patients Undergoing Genetic Investigation and Counseling of Long QT Syndrome or Hypertrophic Cardiomyopathy: A One Year Follow-up

Since Long QT syndrome and Hypertrophic cardiomyopathy are inherited cardiac disorders that may cause syncope, palpitations, serious arrhythmias, and sudden cardiac death, at-risk individuals may experience heart-focused anxiety. In a prospective multi-site study, 126 Norwegian patients attending genetic counseling were followed 1 year with multiple administration of questionnaires, including the Cardiac Anxiety Questionnaire, measuring three distinct symptoms of heart-focused anxiety- avoidance, attention, and fear—in mixed linear analyses. Overall, at 1-year follow-up, patients with clinical diagnosis as compared to patients at genetic risk had significantly higher scores of avoidance (p < .002), attention (p < .005), and fear (p < .007). Sudden cardiac death in close relatives, uncertainty whether other relatives previously had undergone genetic testing, patients’ perceived general health, self-efficacy expectations and procedural satisfaction with genetic counseling were influential in predicting the different symptoms of heart-focused anxiety over time.     

Norwegian airline passengers are not more afraid of flying after the terror act of September 11. The flight anxiety,however, is significantly attributed to acts of terrorism

The aim of this paper is to study: (1) the prevalence of flight anxiety among Norwegian airline passengers; (2) situations that may be of concern during flights and situations not related to flying; (3) whether passengers feel more afraid after the terror act of September 11, 2001; and (4) whether passengers were more afraid in 2002 than in 1986.A questionnaire was distributed during domestic flights in Norway in 1986 and 2002. To asses flight anxiety, a six point scale was used, from 0 = not afraid at all, to 5 = always very afraid, and sometimes avoid flying because of that. A 10‐cm visual analogue scale (VAS) was used to measure the degree of anxiety. There were 50.8% who were not afraid at all. There were 12 women (5.2%) and one man (0.4%) with flight phobia. However, 22 (4.5%) had cancelled flights because of anxiety during the last two years. Situations that caused most concern during flights were turbulence and fear of terrorism and highjacking. After September 11, 48% were not more afraid, 38% a little more, 10% moderately, 3% rather much and 2% very much. The passengers, however, were not more afraid of flying in 2002 than in 1986. About 3% of Norwegian airline passengers have a flight phobia. Women are significantly more concerned than men. The impact of the terror act September 11, 2001 was rather moderate. The level of flight anxiety among Norwegian airline passengers was not significantly different in 2002 and 1986.     

The reliability and validity of the Swedish version of the Body Shape Questionnaire

Psychometric properties of the Swedish version of the Body Shape Questionnaire (BSQ) were examined using data from three samples: (1) a sample from the general population (n= 1157), (2) a student sample (n= 124) and (3) a clinical sample (n= 90). Analyses showed that a single factor solution might be a reasonable solution as 32 of the 34 items loaded heavily on the first factor. The derived short 14-item version of the BSQ also showed a coherent structure with all the items loading on one single factor. The BSQ showed high test-retest reliability, very high internal consistency, ranging from 0.94 to 0.97, and high split-half reliability (above 0.93). Furthermore, it showed high validity by correlating highly with the body dissatisfaction subscale of the Eating Disorders Inventory (r= 0.72 and higher), and high discriminant validity. Thus, the Swedish version of the BSQ showed good concurrent and discriminant validity as well as high reliability.     

Assessing Type A behavior in children: a longitudinal exploration of the overlap between Type A behavior and hyperactivity

Child Type A behavior and its relation to hyperactivity were investigated developmentally using a longitudinal normal sample of 91 children (46 boys and 45 girls) between the ages of 4 and 8-9. In light of the overlap found in several studies between Type A behavior, as measured by the Matthews Youth Test for Health (MYTH) questionnaire, and hyperactivity measured by questionnaires, an attempt was made to measure Type A behavior as distinct from hyperactivity using behavioral observations. The MYTH questionnaire and behavioral observations were used to assess Type A behavior and questionnaire-based measures and behavioral observations were used to assess hyperactivity. Predictions were made regarding individual stability in phenomena and in measures. The results indicated considerable stability in the respective Type A and hyperactivity measures over time, and further, that behavioral observations make it possible to measure Global Type A behavior and Type A Competitiveness as distinct from hyperactivity, although the status of Type A Impatience at early ages is not yet settled. The MYTH and the observed Type A behavior showed differential relations to external criteria, such as achievement measures and problem behavior. This has implications for future measurement and perhaps conceptualization of Type A behavior in children, and thereby also for studying the developmental aspects of Type A behavior.     

A Norwegian adaptation of the Penn State Worry Questionnaire: factor structure, reliability, validity and norms

A Norwegian version of the Penn State Worry Questionnaire (PSWQ) was administered to 304 undergraduate students together with the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI) and the Maudsley Obsessive Compulsive Inventory (MOCI). The PSWQ was also administered to a community sample comprising 879 subjects, together with the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI II) and the White Bear Suppression Inventory (WBSI). Structural equation modeling showed that a three-factor solution of the PSWQ gave the best goodness of fit. The Norwegian version of the PSWQ demonstrated adequate psychometric properties in terms of reliability and validity in both samples. Females scored higher than males on PSWQ.     

Adolescent Suicide Attempters: What Predicts Future Suicidal Acts?

Predictors for repetition of suicide attempts were evaluated among 92 adolescent suicide attempters 9 years after an index suicide attempt (90% females). Five were dead, two by suicide. Thirty-one (42%) of 73 had repeated a suicide attempt. In multiple Cox regression analysis, four factors had an independent predictive effect: comorbid disorders, hopelessness, having ever received treatment for mental or behavior problems, and having a father exerting control without affection. Prediction on an individual level was difficult. Since almost half repeated a suicidal act, the best strategy is to evaluate all adolescent suicide attempters thoroughly and provide treatment as needed.
