Neuropsychological Performance in Gulf War Era Veterans: Traumatic Stress Symptomatology and Exposure to Chemical–Biological Warfare Agents

Because complaints of diminished concentration and memory are among the most common health symptoms reported by Gulf War (GW) veterans with unexplained illnesses, this study investigated neuropsychological functions among GW veterans and controls. Relationships between neuropsychological performance, severity of posttraumatic stress disorder (PTSD) symptomatology, and exposure to chemical–biological warfare agents (CBW) were assessed. Participants were 225 veterans recruited from three cohorts: GW-deployed veterans from Ft. Devens, MA ( n = 141) and New Orleans, LA (n = 37), and Germany-deployed veterans from a Maine National Guard unit (n = 47). A comprehensive evaluation was completed. Severity of subclinical PTSD symptomatology was significantly related to scores on specific neuropsychological tests. PTSD symptom severity in GW-deployed veterans was found to be greater and associated with a broader range of neuropsychological deficits than in Germany-deployed veterans. PTSD severity was associated with lower performance on a range of neuropsychological tasks, whereas CBW exposure contributed to performance deficits on specific cognitive tasks.     

Cognitive Functioning in Treatment-Seeking Gulf War Veterans: Pyridostigmine Bromide Use and PTSD

Gulf War (GW) deployed veterans have reported health symptoms since returning from the war that suggest dysfunction of the central nervous system (CNS). These symptoms include memory and concentration difficulties, fatigue, and headaches. Leading hypotheses for the etiology of these cognitive complaints include psychological factors and/or exposures to chemicals with neurotoxic properties. In this study, cognitive functioning was compared in treatment-seeking GW-deployed veterans and a treatment-seeking non–GW-deployed veteran control group. Results indicated that GW-deployed veterans performed significantly worse than the comparison group on tests of attention, visuospatial skills, visual memory, and mood. GW-deployed veterans who reported taking pyridostigmine bromide (PB) performed worse than GW-deployed veterans without PB use on executive system tasks. Treatment-seeking GW-deployed veterans with diagnoses of posttraumatic stress disorder (PTSD) did not differ on cognitive test measures compared with GW-deployed veterans without PTSD. No interaction effect of PTSD and PB use was found.     

Group counselling by telephone

Six women who responded independently to a television programme about cancer were brought together through the medium of teleconferencing. The life of the group is described. The outcome confirmed the facilitators' belief that the medium is an excellent means of providing short-term process work. It helps to reduce the isolation that many people with cancer speak of, particularly after they have completed any treatment and are not regularly attending hospital. Further, it is a cost-effective and time-effective way of bringing people together.     

Preserving integrity against colonization

Genuine reconciliation between first- and third-person methodologies and knowledge requires respect for both phenomenological and scientific epistemologies. Recent pragmatic, theoretical, and verbal attempts at reconciliation by cognitive scientists compromise phenomenological method and knowledge. The basic question is thus: how do we begin reconciling first- and third-person epistemologies? Because life is the unifying concept across phenomenological and cognitive disciplines, a concept consistently if differentially exemplified in and by the phenomenon of movement, conceptual complementarities anchored in the animate properly provide the foundation for reconciliation. Research by people in neuroscience and in dynamic systems theory substantiate this thesis, providing fundamental examples of conceptual complementarity between phenomenology and science.     

The relationship between adolescent depression and a history of sexual abuse

The purpose of this study was to examine the occurrence of depression among adolescents attending family planning clinics, and to determine the relationship among depression, a history of sexual abuse, and other risk behaviors. The sample consisted of 279 minority females. Results of the study indicated that 40 adolescents (14.3%) scored at or above a raw score of 77 for depression based on the Reynolds Adolescent Depression Scale (RADS). This suggests that these adolescents should be identified for further evaluation. Results of the Stepwise Linear Regression indicated that a history of sexual abuse was the most potent factor in predicting depression. These findings highlight the importance of screening concurrently for depression and a history of sexual abuse in family planning and other healthcare settings.     

Finding common ground between evolutionary biology and continental philosophy

This article identifies already existing theoretical and methodological commonalities between evolutionary biology and phenomenology, concentrating specifically on their common pursuit of origins. It identifies in passing theoretical support from evolutionary biology for present-day concerns in philosophy, singling out Sartre’s conception of fraternity as an example. It anchors its analysis of the common pursuit of origins in Husserl’s consistent recognition of the grounding significance of Nature and in his consistent recognition of animate forms of life other than human. It enumerates and exemplifies five basic errors of continental philosophers with respect to Nature, errors testifying to a philosophical fundamentalism that distorts the intricate interconnections and relationships of Nature in favor of a preferred knowledge rooted in ontological reductionism. It shows that to discover and appreciate the common ground, one must indeed study “the things themselves.”

CONTINGENT PAYMENT PROCEDURES FOR SMOKING REDUCTION AND CESSATION

We assessed the ability of a combined contingent reinforcement and intensive monitoring procedure to promote and sustain temporary smoking cessation among 34 hired research volunteers, and the ability of a smoking reduction test to predict the subsequent initiation of abstinence. During the 5-day cutdown test, subjects were paid from $0 to $6 per day depending on the extent of reduction from baseline CO levels. During the abstinence test, breath samples were obtained three times daily and subjects were paid $4 for each CO reading ≤11 ppm. Sixty-eight percent of subjects initiated abstinence. Of the breath samples collected during the abstinence test (91% of scheduled samples), 96.5% were ≤11 ppm and 80.5% were ≤8 ppm. Subjects who earned more money during the cutdown test were more likely to abstain (r = ?0.51, p < .001). Contingent reinforcement and intensive monitoring procedures appear to have usefulness for analog studies of smoking reduction and cessation.     

An empirical-phenomenological critique of the social construction of infancy

Developmental and clinical psychological findings on infancy over the past twenty years and more refute in striking ways both Piaget's and Lacan's negative characterizations of infants. Piaget's thesis is that the infant has an undifferentiated sense of self; Lacan's thesis is that the infant is no more than a fragmented piece of goods — a corps morcelé. Through an examination of recent and notable analyses of infancy by infant psychiatrist Daniel Stern, this paper highlights important features within the radically different accounts. In particular, it examines Stern's account of self-agency —a facet of the core self. In doing so, the paper brings to light corporeal matters of fact and shows :how recent developmental-clinical data on infants accord with facets of bodily life described by Husserl. The paper contrasts these corporeal matters of fact and facets of bodily life with Piaget's and Lacan's notion of an infant as incompetent and deficient. On the basis of its empirical-phenomenological findings, the paper underscores the need to recognize the richness of nonverbal life and to give movement and the tactile-kinesthetic body their conceptual due.     

The role of facial colour and luminance in visual and audiovisual speech perception

We conducted four experiments to investigate the role of colour and luminance information in visual and audiovisual speech perception. In experiments 1a (stimuli presented in quiet conditions) and 1b (stimuli presented in auditory noise), face display types comprised naturalistic colour (NC), grey-scale (GS), and luminance inverted (LI) faces. In experiments 2a (quiet) and 2b (noise), face display types comprised NC, colour inverted (CI), LI, and colour and luminance inverted (CLI) faces. Six syllables and twenty-two words were used to produce auditory and visual speech stimuli. Auditory and visual signals were combined to produce congruent and incongruent audiovisual speech stimuli. Experiments 1a and 1b showed that perception of visual speech, and its influence on identifying the auditory components of congruent and incongruent audiovisual speech, was less for LI than for either NC or GS faces, which produced identical results. Experiments 2a and 2b showed that perception of visual speech, and influences on perception of incongruent auditory speech, was less for LI and CLI faces than for NC and CI faces (which produced identical patterns of performance). Our findings for NC and CI faces suggest that colour is not critical for perception of visual and audiovisual speech. The effect of luminance inversion on performance accuracy was relatively small (5%), which suggests that the luminance information preserved in LI faces is important for the processing of visual and audiovisual speech.
