Alertness and cognitive control: Is there a spatial attention constraint?

Congruency effects in arrow flanker tasks are often larger when subjects are more alert, suggesting an unusual connection between alertness and cognitive control. Theoretical accounts of the alerting–congruency interaction differ with respect to whether and how spatial attention is involved. In the present study, the author conducted eight experiments to determine whether there is a spatial attention constraint linking alertness to cognitive control. Alertness was manipulated in color-word Stroop tasks involving stimuli that were spatially integrated (Experiments 1–3) or separated (Experiments 4 and 5), as well as in Stroop-like tasks involving spatially separated stimuli for which the irrelevant stimulus features were spatial words (Experiments 6 and 7) or arrows (Experiment 8). All experiments yielded effects of alerting and congruency, but none produced the alerting–congruency interaction typically found with arrow flanker tasks. The results suggest that there is a spatial attention constraint on the relationship between alertness and cognitive control, part of which might involve having a task goal associated with spatial information processing.     

Prenatal stress alters early neurobehavior, stress reactivity and learning in non-human primates: a brief review

In this paper we review three prospective longitudinal studies from our laboratory examining the effects of prenatal stress on early neuro behavior, stress reactivity and learning performance in rhesus monkeys. Either a noise stressor or ACTH treatment was administered to pregnant monkeys during specific periods of pregnancy and offspring were examined repeatedly across development. In all three studies, the prenatally stressed monkeys showed reduced attention and impaired neuromotor functioning during the first month of life compared to controls from undisturbed pregnancies. When the monkeys were separated from their mothers or peers at 6-8 months of age, prenatally stressed monkeys exhibited more disturbance behavior and showed hypothalamic-pituitary-adrenal axis dysregulation. During adolescence, they exhibited impairments in learning, compared to controls.     

Binocular detection of masked patterns in young and old observers

A visual pattern embedded in noise is detected appreciably better when the stimulus complex contains interocular cues (dichoptic condition) than when such cues are absent (binoptic condition). In a recent study (F. Speranza, G. Moraglia, & B. A. Schneider, 1995) the authors showed that the relative difference between binoptic and dichoptic thresholds does not change with age. However, older adults showed higher binoptic and dichoptic thresholds, thus suggesting an age-related difficulty with degraded stimulation. In this article the authors first replicated these findings and proceeded next to investigating whether age-related changes in processing efficiency, additive internal noise, and the spatial frequency bandwidth of the detecting filters could account, separately or concurrently, for the elevated thresholds in noise exhibited by the older adults. Results indicate that this increase is not attributable to age-related changes in filter bandwidth or internal noise. Rather, the findings can be explained in terms of a decrease in processing efficiency with age.     

Systems change as an outcome and a process in the work of community collaboratives for health

The widespread development of comprehensive community initiatives that aim to improve community health is driven by the need to change the systems charged with delivering the services and creating the policies related to a variety of health outcomes. Georgia's Family Connection initiative is the nation's largest statewide network of community collaboratives for health, with collaboratives operating in 159 counties. Data on community context, collaborative processes, engagement in systems change, and changes in programs and activities implemented, gathered consistently at the collaborative level over 3 years, will be used to answer the following questions. How do community contexts and the structure and processes of collaboratives affect implementation of systems change? How do systems changes affect intermediate outcomes such as the type of programs offered in a community? Longitudinal change in systems change and program implementation is described and significant predictors of between‐collaborative variation in longitudinal change for each outcome are identified.     

Standards der sozialmedizinischen Leistungsbegutachtung in der Psychosomatischen Medizin und Psychotherapie

Sociomedical problems are playing an increasingly important role in both psychosomatic medicine and psychotherapy and in psychiatry. The present article examines the standards relating to content and method in sociomedical assessments, primarily in the discipline of psychosomatic medicine and psychotherapy. The focus is on the assessment of performance, highlighting the fact that performance and performance deficits cannot primarily be derived from the medical diagnosis; instead, psychosocial variables that influence the processes of dealing with disease in particular affect the actual performance status. The article pays particular attention to aspects that aggravate or dissimulate performance competence. Finally, the principles of integrating the various findings and results that are incorporated into the assessment report are outlined.     

Neurofibromatosis Type 1 in Genetic Counseling Practice: Recommendations of the National Society of Genetic Counselors

The objective of this document is to provide recommendations for the genetic counseling of patients and families undergoing evaluation for neurofibromatosis type 1 (NF1) or who have received a diagnosis of NF1. These recommendations are the opinions of a multi-center working group of genetic counselors with expertise in the care of individuals with NF1. These recommendations are based on the committee’s clinical experiences, a review of pertinent English language medical articles, and reports of expert committees. These recommendations are not intended to dictate an exclusive course of management, nor does the use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider’s professional judgment based on the clinical circumstances of an individual patient. Both Heather B. Radtke and Courtney D. Sebold contributed equally to this document.     

The Experiential Liberation Strategy of the Existential-Integrative Model of Therapy

This article summarizes the experiential liberation strategy of the existential-integrative (EI) model of therapy. The existential-integrative model of therapy provides one way to understand and coordinate a variety of intervention modes within an overarching ontological or experiential context. I will (1) define the experiential liberation strategy—such as its emphasis on the capacities to constrict, expand, and center psychophysiological capacities; (2) describe its salient features—such as the four stances that promote experiential liberation: presence, invoking the actual, vivifying and confronting resistance, and the cultivation of meaning and awe; and (3) illustrate the relevance of the strategy to case vignettes drawn from actual practice.

Task switching versus cue switching: using transition cuing to disentangle sequential effects in task-switching performance

Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue switches and cue repetitions) and task transitions (task switches and task repetitions) can be examined in a complete factorial design. Transition cuing removes the confound between cue transitions and first-order task transitions, but it introduces a confound between cue transitions and longer task sequences. In the present study, transition cuing was studied with two cues per transition (REPEAT and AGAIN for task repetitions; SWITCH and CHANGE for task switches), enabling a partial deconfounding of cue transitions and task sequences. Two experiments revealed robust sequential effects, with higher order task transitions affecting performance when cue transitions were held constant and with cue transitions affecting performance when task sequences were held constant. Methodological and theoretical implications of these findings for research on task switching are discussed.     

Whither Goest Personality at Work?: Overview of the special issue on "Work and Personality"

En s'appuyant sur les articles présentés, cette discussion insiste sur le fait qu'un programme de recherche sur la personnalité doit inclure, mais aussi dépasser, la sélection du personnel et le modèle en cinq facteurs. Les sujets suivants sont briévement abordés: (a) le rôle central que joue le comportement dans la compréhension de l'impact de la personnalité et des relations situation-personnalité; (b) le rôle de l'adaptation personne-environnement dans la compréhension du comportement au sein de l'organisation et de la liaison validité-critères; et (c) l'intérêt de faire appel à des concepts individuels, tel que l'identité, pour enrichir les études portant sur le thème "personnalité et travail". La conclusion de ces commentaires est qu'un bilan approfondi des recherches sur la personnalité, comme celui de ce numéro spécial, débouchera sur un champ d'investigation vivant à l'avenir assuré.
Using the contributed papers as a base, this discussion proposes that an agenda for research on personality should include, but go beyond, personnel selection and the five-factor model. The following topics are briefly discussed: (a) the central role that behaviour plays in understanding personality-outcome and situation-personality relationships; (b) the role of person-environment fit in understanding criterion-related validity and organisational behaviour; and (c) the usefulness of adding individual constructs, like identity, to the issues studied at work under the personality rubric. The commentary concludes with the thought that a broad research agenda on personality, like the one represented in this special issue, will produce a vibrant and long-lived field of inquiry.
