The influence of phonological neighborhood on visual word perception

In the research reported here, we investigated the influence of phonological neighborhood density on the processing of words in the visual lexical decision task. The results of the first experiment revealed that words with large phonological neighborhoods were verified more rapidly than words with small phonological neighborhoods. In the second experiment, we replicated this effect with a more tightly controlled set of stimuli. These results demonstrate the importance of phonological codes when processing visually presented letter strings. We relate this research to previous results on semantic and orthographic neighborhoods and discuss the results within the context of a model in which lexical decisions are based on stimulus familiarity.     

The Salient Stressor Impact Questionnaire (SSIQ): a measurement of the intensity and chronicity of stress

High stress is known to affect health, but stress impact, determined by events and responses to them, has not been studied systematically. For the Salient Stressor Impact Questionnaire (SSIQ), the impact of events was assumed to depend on their salience and chronicity and the impact of responses on their chronicity and intensity with greater unfavorable appraisal associated with greater response. The SSIQ assessed a person's two most salient stressors. Chronicity items discriminated between clinically stressed and nonclinical participants and measured the chronicity of stressful feelings (distress) and the event. The remaining items measured the degree of distress and unfavorable appraisal. The SSIQ showed good test-retest and internal consistency reliability, concurrent validity, and stability across diverse populations. Exploratory analyses grouped items into distress, chronicity, and appraisal elements, and confirmatory analysis revealed a good fit to the hypothesized model. Preliminary data suggest that the SSIQ will be useful for studying relationships between stress and health.

ADHD outside the laboratory: boys' executive function performance on tasks in videogame play and on a visit to the zoo

One current theory of attention-deficit/hyperactivity disorder (ADHD) proposes that a primary deficit in behavioral inhibition gives rise to secondary deficits in 4 executive functions and motor control. To date, empirical support for this model is based primarily on laboratory-based cognitive methods. This study assessed behavioral inhibition and executive functioning in children with ADHD in 2 real-life contexts: videogames (motor-skill target game, cognitively demanding adventure game) and an outing at the zoo (route tasks). Participants were a community sample of 57 boys diagnosed with ADHD (20 inattentive, 37 combined type) and 57 normally developing control boys, matched individually for age and nonverbal IQ. Operationally defined measures of behavioral inhibition and specific executive functions were derived from these activities and assessed under contrasting conditions of low or high working memory and distractor loads. There were no group differences in basic motor skills on the target game, nor in terms of the ability to inhibit a prepotent or ongoing response in the adventure videogame. However, boys with ADHD exhibited more self-talk, more effortful response preparation, and completed fewer challenges in the latter videogame. Also, they manifested inhibition deficits in terms of interference control during the route task at the zoo and took longer to complete the tasks. Typically, these differences were greatest under conditions of high working memory and distractor loads. Findings from this study suggest that cognitive difficulties in ADHD may be context dependent and that ADHD is associated with deficits in some but not all aspects of behavioral inhibition.     

Psychoanalysis and healing by faith

It would be preposterous to assume that this brief chapter out of my book tells all that can be said about the relationship of religious faith to science in general, to the therapeutic process, and to psychoanalysis in particular. The most that we can claim for it is that without cluttering it up with the excess verbal baggage of philosophical rationalization, it has stated simply some of the issues as honest men must face them. Certainly the history of the world has proved again and again that science and religion can both be perverted to amoral ends; but it is equally true that science and religion can both express man's search for the good life. The critical issue is whether they can carry on that search hand in hand, or whether their basic premises and their essential techniques are irreconcilably opposed. It was once the fortune of the author to hear a great religious teacher say in the pulpit that religion is a search for truth; but that as soon as any religion thought that it had found the truth, it ceased to be a religion. With such a concept of religion every scientist will find himself in full agreement. Unfortunately, however, among men of religion as among scientists, there are those whose spirits are so meager that they cannot live without absolutes; and in both camps they tend to aggregate to themselves a predominance of power. Apart from theoretical issues, this practical fact may make a confict between opposing totalitarians irreconcilable.
