Detecting malingered neurocognitive dysfunction using the reliable digit span in traumatic brain injury

This study assessed the effectiveness of Greiffenstein's Reliable Digit Span (RDS) score for the detection of malingered neurocognitive dysfunction. Participants were 54 traumatic brain injury patients referred for neuropsychological evaluation. Twenty-four met the Slick, Sherman, and Iverson criteria for at least probable malingered neurocognitive dysfunction. The control group was composed of 30 patients without external incentive and who thus did not meet the Slick criteria. All patients completed the digit span test as part of either the WAIS-R or WAIS-III. The RDS scores were calculated, and sensitivity, specificity, and predictive power were examined for several cutoffs. Classification accuracy for the RDS was excellent. Issues related to the clinical application of this technique are discussed.     

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.     

Correlates of exercise adherence in an African American church community

This study identified correlates of attendance to a community-based exercise program in an African American church congregation. After medical clearance, 48 participants completed measures of social support, health-related quality of life, depression, exercise self-efficacy, and exercise motivation and then participated in an exercise program for 6 months (attendance rate = 27%). Age, a sense of affiliation as a motivator to exercise, and weekly caloric expenditure derived from yard work were positively associated with program attendance, and full- or part-time employment was negatively associated with attendance. The authors concluded that exercise adherence is a complicated phenomenon that is influenced by a variety of environmental, personal, and social factors. Social factors, in particular, may be important in promoting adherence to an exercise program in African Americans.     

Ethnicity,gender, and academic self-concept: a preliminary examination of academic disidentification and implications for psychologists

This study examined data from 358 African American students and 229 European American students to determine if the phenomenon of academic disidentification occurred. Analyses revealed that among African American male students, the relationship between academic self-concept and grade point average (GPA) significantly decreased, whereas the relationship between academic self-concept, self-esteem, and GPA significantly increased for European American female students. The relationship between academic self-concept and GPA remained significant for African American female and European American male students. Research and counseling implications are discussed.     

Weak central coherence,poor joint attention,and low verbal ability: independent deficits in early autism

C. Jarrold, W. Butler, E. M. Cottington, and F. Jiminez (2000) proposed that weak central coherence is a primary cognitive deficit in autism and speculated that it may even account for theory of mind impairments. The current study investigated whether weak central coherence could account for deficits in 2 behaviors purported to tap capabilities fundamental to a theory of mind: joint attention and pretend play. Twenty-one children (ages 3-5 years) with autism spectrum disorders were matched to 21 control children on chronological age, nonverbal ability, and gender. Pretend play did not differentiate the groups. Weak central coherence, poor joint attention, and low verbal ability contributed significantly and independently to the prediction of autism group membership, a finding consistent with 3 independent cognitive deficits underlying autism.     

High-quality work,job satisfaction,and occupational injuries

The authors investigated whether and how 1 element of a high-performance work system, namely high-quality jobs (composed of extensive training, variety, and autonomy), affects occupational injuries. On the basis of data from the Australian WIRS95 database (N = 16,466; Department of Workplace Relations and Small Business, 1997), high-quality jobs exerted a direct effect on injuries and an indirect effect through the mediating influence of job satisfaction. Conceptual, methodological, and practical issues are discussed.     

Contrasting role morality and professional morality: implications for practice

Abstract The notion of role morality suggests individuals may adopt a different morality depending on the roles they undertake. Investigating role morality is important, since the mentality of role morality may allow agents to believe they can abdicate moral responsibility when acting in a role. This is particularly significant in the literature dealing with professional morality where professionals, because of their special status, may find themselves at odds with their best moral judgments. Here I tell four stories and draw out some distinctions. I conclude that role morality is a genuine and useful distinction. However, I suggest that the purported distinction between role morality and professional morality is over-determined. Therefore, alleged conflicts between the demands of role and profession (such as the different pressures on Pinto designers as employees and as engineers) are not conflicts between different kinds of demands, but rather conflicts arising from divergent roles that most workers will encounter regularly. Another analytical perspective is to look at moral choices at work in terms of power and the ability to bring about change. Finally, I draw the implication that we should stress moral awareness at a fairly abstract level for all employees and reinforce the moral primacy of individual choice.     

Neural correlates of person recognition

Rapidly identifying known individuals is an essential skill in human society. To elucidate the neural basis of this skill, we monitored brain activity while experimental participants demonstrated their ability to recognize people on the basis of viewing their faces. Each participant first memorized the faces of 20 individuals who were not known to the participants in advance. Each face was presented along with a voice simulating the individual speaking their name and a biographical fact. Following this learning procedure, the associated verbal information could be recalled accurately in response to each face. These learned faces were subsequently viewed together with new faces in a memory task. Subjects made a yes-no recognition decision in response to each face while also covertly retrieving the person-specific information associated with each learned face. Brain activity that accompanied this retrieval of person-specific information was contrasted to that when new faces were processed. Functional magnetic resonance imaging in 10 participants showed that several brain regions were activated during blocks of learned faces, including left hippocampus, left middle temporal gyrus, left insula, and bilateral cerebellum. Recordings of event-related brain potentials in 10 other participants tracked the time course of face processing and showed that learned faces engaged neural activity responsible for person recognition 300-600 msec after face onset. Collectively, these results suggest that the visual input of a recently learned face can rapidly trigger retrieval of associated person-specific information through reactivation of distributed cortical networks linked via hippocampal connections.     

Spirituality, depression, and loneliness among Jewish seniors residing in New York City

This article reports the results of research that examined a randomized group of 118 Jewish seniors who were clients of one of three Jewish social service agencies in New York City. They were interviewed by four Clinical Pastoral Education residents at the Jewish Institute for Pastoral Care. During the interview, participants were asked to respond to the questions contained in the Brief Depression Scale, Version 3 of the UCLA Loneliness Scale, and the Index of Core Spiritual Experience--INSPIRIT. A statistically significant positive correlation was found between the depression and loneliness scores, r(116) = .56, p < .001. Spirituality was not correlated with either of these scales. Both depression and loneliness were significantly higher among women, among people who had physical impairments and those who had been victims of Nazi persecution. Depression and loneliness were inversely related to participants' ability to venture out of their house and to their relationship with their families. Having a sense of meaning or purpose in life was also inversely related to depression and loneliness. Spirituality tended to be higher among women, those participants, with more years of religious education, and those with physical impairments, but only the gender effect was statistically significant.
