Interrelationships between Reading Disability and Attention-Deficit/Hyperactivity Disorder

Evidence from a number of investigations suggests a considerable overlap between reading disability (RD) and attention deficit-hyperactivity disorder (ADHD). We investigate the relationship between RD and ADHD in a cohort of 186 children 7.5–9.5 years of age, recruited explicitly to address classification and definitional issues in these disorders. Using multivariate methods, we examine the hypothesis that RD and ADHD represent separate diagnostic entities that frequently co-occur in the same individual. The results suggest that RD is characterized by deficits within the language system, in particular a subcomponent within that system, phonological processing; in contrast, such linguistic deficits are not characteristic of ADHD unless ADHD is associated with RD. When children with both RD and ADHD are examined, both the linguistic deficits associated with RD and the behavioral characteristics associated with ADHD are apparent, but these deficits are not synergistic. We conclude that RD and ADHD represent separate disorders that frequently co-occur.     

The Relation of Lifetime Cognitive Activity and Lifetime Access to Resources to Late-life Cognitive Function in Older African Americans

ABSTRACT

Research in older Caucasians has demonstrated that cognitive activity is related to cognitive function in late adulthood. Knowledge of this association is limited in older minority populations. We examined the relation of cognitive activity and access to cognitive resources, with cognitive function in a group of 108 older African Americans. We constructed two scales to measure the frequency of cognitive activity and the presence of resources that promote cognitive activity during early and late life. Both measures had high internal consistency and the cognitive activity scale had adequate temporal stability over a 4-week interval. In analyses that controlled for age and education, more frequent lifetime cognitive activity was related to current cognitive function, but lifetime cognitive resources only approached significance. The results suggest that both measures are psychometrically sound in a minority population and that lifetime cognitive activity may contribute to current cognitive function in African Americans.     

Anticipating the Societal Challenges of Nanotechnologies

“In this article we sketch out the landscape for this Special Issue on anticipating and embedding the societal challenge of nanotechnologies. Tools that actors may choose to employ for these processes are articulated, and further explored through the introduction of the seven articles which comprise this Issue. Taken together, these articles create a cogent narrative on the societal challenges posed by nanotechnologies. They are drawn together by three distinct themes, each of which is briefly considered within this context of this Introductory article”.     

Information underpinning anticipation of goal-directed throwing

We identified the information used to anticipate throw direction in handball. In two experiments, we examined how anticipation performance is affected when the information from one of five body areas (right arm, shoulders, hips, trunk, or total throw side) was either neutralized or decoupled from the motion of other body segments. In the first experiment, performance was significantly reduced when information from the throwing arm was neutralized, irrespective of skill levels. Skilled participants were negatively affected when the shoulders, hips, and trunk were neutralized, whereas less-skilled participants showed trends toward improvement under identical conditions. In the second experiment, partially disrupting relative motion via decoupling was not enough to reduce the anticipation performance among skilled participants to chance levels, whereas less-skilled participants lost their ability to anticipate in three conditions. Our findings suggest that skilled and less-skilled participants employ different information extraction strategies, yet information from the throwing arm is critical to anticipation for both groups. The two experiments suggest that relative motion mediated by both the absolute displacement trajectories of individual marker locations and their relative timings are important in informing anticipation, irrespective of skill level.     

Explanatory Style and Health: Mechanisms Linking Pessimism to Illness1

This study tests the relationship between pessimistic explanatory style and illness with questionnaire data. Questionnaires were administered to 234 college students at a mid‐sized Western university. Four variables were tested as potential mediators of the pessimistic explanatory style/illness relationship: symptoms of depression, perceived stress, social support, and poor health practices. Results indicated that only the global dimension of pessimistic explanatory style was related to experiences of illness, and hence was the only dimension that could be mediated by the proposed variables. Results demonstrated that symptoms of depression mediated the relationship between global attributions for negative events and illness. Exploratory analyses also suggest that stress is implicated in this process such that it increases symptoms of depression, which in turn influence illness.     

Developing Standard Recommendations (Guidelines) for Genetic Counseling Practice: A Process of the National Society of Genetic Counselors

The National Society of Genetic Counselors (NSGC) supports the development of practice recommendations (guidelines) in the field of genetic counseling. This paper reviews the basic components of NSGC genetic counseling practice recommendations as well as the process for formal adoption of such documents, as approved by the Board of Directors of the NSGC.     

Gerard Manley Hopkins on Planet Earth

Nineteenth-century Jesuit priest and poet, Gerd Manley Hopkins (1844–89), produced poems on natural themes which were not only revolutionary for their structure and style but also disctinctive and forward-looking for their treatment of the environment. In these poems, he presents nature as intrinsically (rather than instrumentally) valuable, God as concerned with the salvation not only of humans but of the environment, and humankind as responsible noy only for polluting the Earth but for participating in its salvation. Christian poets of the twenty-first century need to hees and follow Hopkin's example.
