Approaches to Cognitive Remediation of Neuropsychological Deficits in Schizophrenia: A Review and Meta-Analysis

A review and critique of the literature pertaining to the use of cognitive remediation techniques in patients with schizophrenia is presented. The review is organized into three sections, according to the neuropsychological deficit targeted for remediation: 1) executive-function, 2) attention, and 3) memory. With regards to executive-function, despite an initial report suggesting that Wisconsin Card Sorting Test performance cannot be remediated, subsequent studies suggest that performance can be improved on a variety of dependent measures including perseverative errors, categories achieved, and conceptual level responses. These observations were confirmed by a meta-analytic investigation that revealed large mean effects sizes (d ₊ = 0.96) for these studies. Effect sizes were homogenous across discrepant remediation strategies and dependent measures. With regards to attention, serial scanning can be improved with instruction and reinforcement, whereas there is mixed evidence suggesting that practice-based attention drills can improve performance on measures of sustained attention in schizophrenia. With regards to memory, relatively simple semantic and affective elaborate encoding strategies elevates verbal list-learning memory in patients with schizophrenia to levels consistent with controls. A similar encoding procedure, combined with vigilance training, produces substantial improvement in social cue recognition. Avenues for future research are discussed.     

Sex steroids and human behavior: implications for developmental psychopathology

In a variety of mammalian species, prenatal androgens organize brain structures and functions that are later activated by steroid hormones in postnatal life. In humans, studies of individuals with typical and atypical development suggest that sex differences in reproductive and nonreproductive behavior derive in part from similar prenatal and postnatal steroid effects on brain development. This paper provides a summary of research investigating hormonal influences on human behavior and describes how sex differences in the prevalences and natural histories of developmental psychopathologies may be consistent with these steroid effects. An association between patterns of sexual differentiation and specific forms of psychopathology suggests novel avenues for assessing the effects of sex steroids on brain structure and function, which may in turn improve our understanding of typical and atypical development in women and men.     

The Matter of Religion and Science: Response to Huston Smith

Huston Smith's Why Religion Matters is the culminating reflections of one of the most respected religion scholars of our day. In this work, Smith sees modern society to be in the midst of a spiritual crisis. According to Smith, this crisis has been brought about by the advance of science and the inroads into what Smith calls the traditional worldview. While Smith's work is of some importance, I believe that several of its fundamental claims are mistaken. Smith often does not accurately portray the content of science and frequently conflates the actual practice of science with philosophical scientism. Smith wrongly blames science alone for the decline of religion among Western elites. His claim that all religions can be equivocally described in terms of the traditional worldview is also problematic. Despite this, Smith does have a clear conception of what the issues are in the relation between science and religion. It is my hope that these issues will continue to be taken seriously.     

Religion as Orienting Worldview

Religions are complex, and any attempt at defining religion necessarily falls short. Nevertheless, any scholarly inquiry into the nature of religion must use some criteria in order to evaluate and study the character of religious traditions across contexts. To this end, I propose understanding religion in terms of an orienting worldview. Religions are worldviews that are expressed not only in beliefs but also in narratives and symbols. More than this, religions orient action, and any genuine religious tradition necessarily is concerned with normative behavior, whether ethical or religious in character. Such an understanding of religion has several advantages, one of which is its natural relation to current forms of the science-religion dialogue. Not only can the findings of cognitive science and related areas inform us about the nature of religion; scientific discoveries also prove to be important for any religious synthesis that attempts to construct a worldview for the twenty-first century.     

Experiencing the Production of Sounds

It is often supposed that our experience of sounds is as of things distinct from the material world of sight and touch: reflecting on the character of our auditory experience might seem to confirm that. This paper describes the features of our auditory experience that can lead one to think of sounds in this way. It then describes a way we can experience sounds as being part of the material world. Since this is a kind of experience that essentially involves more than one sense, the paper ends by drawing some conclusions about how we should think about the senses.     

Linking Parents' Work Stress to Children's and Adolescents' Psychological Adjustment

Recent research indicates that parental work stress has implications for the quality of family interaction and, in turn, children's and adolescents' adjustment. Studies in two distinct genres are reviewed: investigations relying on global reports of work demands, family dynamics, and child and adolescent adjustment and studies focusing on within-person comparisons of family interaction on days characterized by high and low work stress. The effects of parental work stress on children's and adolescents' adjustment appear to be indirect. Work stress is linked to parents' feelings of overload and strain, which in turn predict lower parent-child acceptance and higher conflict, processes that in turn are related to less positive adjustment of children and adolescents. In the face of high work stress, withdrawing from family involvement may be adaptive in the short run but ultimately problematic. The strength of these associations depends on parents' personality qualities, parents' coping styles, and work and family circumstances.     

How Do People Process Health Information? Applications in an Age of Individualized Communication

Advances in computer technology have made it possible to customize communication, including health-education materials, to the specific needs and interests of any individual. Studies show that individually tailored health-education materials are more effective than generic materials in promoting changes in a variety of health-related behaviors. Theory and research in information processing provide an explanation for why such materials are effective. This article discusses current research on how individuals process tailored health information, and discusses directions for future research in this area.     

“I Was Really, Really, Really Mad!” Children's Use of Evaluative Devices in Narratives About Emotional Events

Children (ages 3, 5, and 8 years, mostly White and middle-class) were asked to tell personal experience narratives about a time when they had been happy, surprised, and mad. Their explicit emotion labels as well as their use of linguistic forms of evaluation to convey emotion were assessed. Five-year-old boys were the most likely to explicitly label anger, while gender and age differences in explicit emotion labels were absent for the other two emotions. However, children used many more linguistic devices for providing evaluation than explicit emotion labels in their narratives. They also provided more with age, and they used more evaluative devices when talking about anger-arousing events than about happy or surprising events. The few gender differences suggested that 3-year-old girls may acquire earlier mastery of evaluative devices than do boys, especially references to emotional states.     

Influence of single and multiple onset distractors on visual search for singleton targets

In three experiments, we examined attentional and oculomotor capture by single and multiple abrupt onsets in a singleton search paradigm. Subjects were instructed to move their eyes as quickly as possible to a color singleton target and to identify a small letter located inside of it. In Experiment 1, taskirrelevant sudden onsets appeared simultaneously on half the trials with the presentation of the color singleton target. Response times (RTs) were longer when onsets appeared in the display regardless of the number of onsets. Eye-scan strategies were also disrupted by the appearance of the onset distractors, although the proportion of trials on which the eyes were directed to the onsets was the same regardless of the number of onsets. In Experiment 2, we manipulated the time of presentation of two taskirrelevant onsets in order to further examine whether multiple onsets would be attended and fixated prior to attending a color singleton target. Again, subjects made a saccade to a task-irrelevant onset on a substantial proportion of trials prior to fixating the target. However, saccades to the second onset were rare. Experiment 3 served as a replication of Experiment 1 but without the requirement for subjects to move their eyes to detect and identify the singleton target. The RT results were consistent with those in Experiment 1; dual onsets had no larger an effect on response speed than single onset distractors. These data are discussed in terms of the interaction between top-down and bottom-up control of attention and the eyes.     

An international comparative study of self-reported driver behavior

Using a large data base of 20,725 questionnaires from 19 European countries, this article uses a combination of factor analysis and tree based regression to determine driver groups with homogeneous self-reported behavior and determine whether regional differences in driving behaviors exist. Self-reported behavior, including speeding, reckless driving, seat belt use, and drinking and driving are examined. The results suggest that speeding and general reckless (dangerous) behavior are related, perhaps capturing a driver's “risk taking” or “pre-trip violations” behavior. Similarly, seat belt use and driving under the influence of alcohol are also related and may represent a driver's “law abiding” tendency or “during-trip violations” behavior. Further, important regional differences and similarities between European drivers are uncovered. Northern European drivers report a significantly higher compliance with drinking and driving laws and seat belt use regulations than do Southern and Eastern European drivers.
