Ask and ye shall receive: behavioural specificity in the accuracy of subjective memory complaints

A cross‐sectional sample of adults completed an extensive set of cognitive tasks and a set of questionnaires measuring depressive affect, memory complaint, and other variables. During an interview about their prescribed medications, the participants also reported whether they were having problems remembering to take the medication as prescribed (an everyday prospective memory problem). Their medication adherence at home was then monitored for one month using pill bottles which microelectronic caps. Cognitive tasks correlated with memory complaints, as measured by the Memory Functioning Questionnaire, but not with problems in remembering to take medications. The highest correlations were with a free recall task. Conversely, reported problems with medication adherence during the interview had good predictive validity for subsequent adherence problems, but not for cognitive tasks, including a measure of prospective memory. Depressive affect was related to both the questionnaire and the interview complaints about medication adherence, but a structural equation model showed that the relationships of cognition and medication adherence to the different memory complaints were independent of depressive affect. The results are interpreted in terms of a behavioural specificity hypothesis, which states that adults' self‐reports of memory problems are valid when they focus directly on specific memory‐related behaviours in everyday contexts.

Assessing the Prevalence of Body Dysmorphic Disorder in an Ethnically Diverse Group of Adolescents

We investigated the prevalence of Body Dysmorphic Disorder (BDD) in an ethnically diverse sample of adolescents (N = 566) using the Body Image Rating Scale, a brief self-report measure for assessing body dissatisfaction. Results showed that adolescent girls were more dissatisfied with their bodies than adolescent boys, and that African-Americans of both genders were less dissatisfied with their bodies than Caucasians, Asians, and Hispanics. The interaction between gender and ethnicity was not significant. We found an overall prevalence for BDD of 2.2%. Although these are the first data on the prevalence of BDD in an ethnically diverse group of adolescents, they are consistent with the other study on the prevalence of BDD in a predominantly Caucasian group of college students.     

William James and the Religious Character of the Sick Soul

The scholarly attention lavished on William James’ case study in the “Sick Soul” lecture in The Varieties of Religious Experience of a man disturbed by the vision of an epileptic patient has generally not approached this case as a religious experience. To deepen our understanding of religious experience, I show that this case study can be understood as religious using elements of the theory of religion expounded throughout James’ text. I argue that it can be understood as a stage in the process of conversion James lays out. The omission of a subsequent stage highlights James’ reasons for rejecting healthy-mindedness as a philosophically adequate perspective and illustrates his claim that the strivings of the conscious mind can stunt the conversion process. Drawing on other philosophical, psychological, and literary texts, I argue that the content of the vision James describes points to solitude as a source of religious disquiet.     

Problems for Dogmatism

I argue that its appearing to you that P does not provide justification for believing that P unless you have independent justification for the denial of skeptical alternatives – hypotheses incompatible with P but such that if they were true, it would still appear to you that P. Thus I challenge the popular view of ‘dogmatism,’ according to which for some contents P, you need only lack reason to suspect that skeptical alternatives are true, in order for an experience as of P to justify belief that P. I pursue three lines of objection to dogmatism, having to do with probabilistic reasoning, considerations of future or hypothetically available justification, and epistemic circularity. I briefly sketch a fall-back position which avoids the problems raised.     

Knowledge of language and knowledge about the world: A reaction time study of invited and necessary inferences

Necessary inferences (e.g., The jury was not able to deliver its verdict by 3 o'clock. The jury did not deliver its verdict by 3 o'clock.) depend on linguistic knowledge. Invited inferences, (e.g., The jury was able to deliver its verdict by 3 o'clock. The jury delivered its verdict by 3 o'clock) depend on knowledge about the world. Responses were faster to necessary than to invited inferences when subjects verified only one of the two inference types (Experiments 1 and 3). When subjects verified both inference types there was no difference between invited and necessary inferences (Experiments 2 and 4). These data suggest that linguistic and world knowledge are psychologically distinct and that when factual knowledge is not needed in a task it is not processed. In Experiments 3 and 4 incongruent world knowledge slowed response times for both inference types. This suggests that linguistic and factual knowledge are both port of the initial representation of a sentence.     

Consciousness avoided

In Consciousness Explained, Dennett systematically deconstructs the notion of consciousness, emptying it of its central and essential features. He fails to recognize the self‐intimating nature of experience, in effect reducing experiences to reports or judgments that so‐and‐so is the case. His information‐processing model of meaning is unable to account for semantics, the way in which speakers and hearers relate strings of symbols to the world. This ability derives ultimately from our animal nature as experiencers, though culturally supplemented in various ways. But Dennett, while successful in rebutting Cartesianism about the mind, fails to take into account our natural history. He claims descent from Wittgenstein in his philosophy of mind, but he shows awareness only of Wittgensteinian's demolition of the private object of experience and overlooks the equally Wittgensteinian theme of humans as products of nature.     

Chronic Effects of Ionizing Radiations and the Hypothesis that Irradiation Produces Aging-Like Changes in Behavior

On the basis of theories and research on cognitive and perceptual processes, several hypotheses concerning psychophysiological differences between high and low creative subjects were made. Thirty male undergraduates were divided into high and low creative groups on the basis of the Remote Associates Test and a version of the Uses Test. Basal alpha index, alpha blocking in response to stimulus onset, and performance on alpha enhancement and suppression in a feedback situation were measured. High creative subjects exhibited a lower alpha index and a greater decrement in alpha due to stimulus onset. High creatives showed immediate acquisition of control in alpha enhancement trials but no improvement across trials, while low creative subjects showed continual improvements and quickly reached the level of control of high creative subjects. High creatives were much better at alpha suppression than at alpha enhancement.
