Qualitative Cancer Genetic Counseling Research, Part I: Ethnography in a Cancer Clinic

This is a report of the experience of several months' ethnographic research by a genetic counselor researcher in a cancer treatment clinic. One goal of the exercise was to directly experience a method of qualitative research known as ethnography, which relies heavily on participant-observation, in an applied clinical setting. Another goal was to explore a previously undescribed research area in the genetic counseling literature, namely, the meaning of cancer and cancer treatment for affected individuals and their support companions. Here we report on a personal account of the experiences of conducting and publishing the research. The preliminary analysis and results of this field experience are published elsewhere (Peters et al. (2001) J Genet Counsel 10(2):151–168.). These initial findings support the feasibility of genetic counselors, who are trained in specific social science methodologies, to conduct qualitative research pertinent to genetic counseling practice.This work was completed at the University of Pittsburgh before employment at the National Cancer Institute (NCI) and does not represent the views of the NCI, the National Institutes of Health, the Department of Health and Human Services, or the Federal Government     

The Five Factor Model (FFM) among four groups of male and female professionals

The present study examined the differences in personality traits among groups of seasoned professionals A Hebrew shortened version of Costa and McCrae’s [Costa, P. T., Jr., & McCrae, R. R. (1992). NEO-PI-R: Professional manual odessa. Florida: Psychological Assessment Resources] NEO-FFI questionnaire was administered to 236 Israeli male and female doctors, lawyers, clinical psychologists, and artists (mean age = 31.19). Artists were found to be significantly more neurotic than members of the other three professional groups and significantly more open to experience than doctors. Women were significantly more neurotic and extravert than men, regardless of their occupational affiliation.     

Multisensory-mediated auditory localization

Multisensory integration is a powerful mechanism for maximizing sensitivity to sensory events. We examined its effects on auditory localization in healthy human subjects. The specific objective was to test whether the relative intensity and location of a seemingly irrelevant visual stimulus would influence auditory localization in accordance with the inverse effectiveness and spatial rules of multisensory integration that have been developed from neurophysiological studies with animals [Stein and Meredith, 1993 The Merging of the Senses (Cambridge, MA: MIT Press)]. Subjects were asked to localize a sound in one condition in which a neutral visual stimulus was either above threshold (supra-threshold) or at threshold. In both cases the spatial disparity of the visual and auditory stimuli was systematically varied. The results reveal that stimulus salience is a critical factor in determining the effect of a neutral visual cue on auditory localization. Visual bias and, hence, perceptual translocation of the auditory stimulus appeared when the visual stimulus was supra-threshold, regardless of its location. However, this was not the case when the visual stimulus was at threshold. In this case, the influence of the visual cue was apparent only when the two cues were spatially coincident and resulted in an enhancement of stimulus localization. These data suggest that the brain uses multiple strategies to integrate multisensory information.     

Anxiety moderates the interplay between cognitive and affective processing

Evidence suggests that focus of attention and cognitive load may each affect emotional processing and that individual differences in anxiety moderate such effects. We examined (a) fear-potentiated startle (FPS) under threat-focused (TF), low-load/alternative-set (LL/AS), and high-load/alternative-set (HL/AS) conditions and (b) the moderating effect of trait anxiety on FPS across these conditions. As predicted, redirecting attentional focus away from threat cues and increasing cognitive load reduced FPS. However, the moderating effects of anxiety were specific to the LL/AS condition. Whereas FPS was comparable for high-anxiety and low-anxiety subjects in the TF and HL/AS conditions, FPS was significantly greater for high-anxiety than for low-anxiety subjects in the LL/AS condition. These results suggest that affective processing requires attentional resources and that exaggerated threat processing in anxious individuals relates to direction of attention rather than emotional reactivity per se.     

The interactive evolution of human communication systems

This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants' horizontal, pair-wise interactions led "bottom up" to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community-evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.     

Long-term cognitive dynamics of fluent reading development

Most theories of reading development assume a shift from slow sequential subword decoding to automatic processing of orthographic word forms. We hypothesized that this shift should be reflected in a concomitant shift in reading-related cognitive functions. The current study investigated the cognitive dynamics underlying reading development in a large school sample ranging from beginning to experienced readers. The results showed that phonological awareness (PA) and rapid automatized naming (RAN) contributed substantially to reading fluency over all six primary school grades. However, the relationship between PA and word (but not pseudoword) reading fluency decreased as a function of reading experience, whereas the relationship between RAN and word reading fluency increased gradually. Moreover, this cognitive shift was most pronounced for high-frequency words. The results seem to point to the development of one (and only one) reading network for all types of words in which processing load or type of processing depends on word familiarity and amount of reading experience.
