Object Perception,Attention, and Memory 2008 Conference Report 16th Annual Meeting,Chicago, IL,USA

We investigated how processing unfolds across time as adults view novel manual activity. Adults advanced through slideshows of an actor performing sleight-of-hand manoeuvres; dwell times were recorded to each slide. As in past work involving larger-scale intentional action scenarios, adults allocated more attention to slides depicting breakpoints—transitions from one event segment to the next—than slides displaying mid-stream action, indicating that dwell times are sensitive to adults' recovery of segmental structure in intricate manual activity. Adults also allocated increased attention towards slides indicative of causal structure, indicating that dwell times index processing of causally relevant information as well as segmental structure. We were additionally curious if adults' learning outcomes would differ as a function of whether they paced themselves or watched slideshows advance at a computer-controlled pace. Memory did not differ, but adults viewing computer-controlled slideshows displayed an advantage in performing the tricks. A single attentional focus may have helped adults learn to re-enact the actions, relative to a split attentional focus.     

Intraclass correlation associated with therapists: estimates and applications in planning psychotherapy research

It is essential that outcome research permit clear conclusions to be drawn about the efficacy of interventions. The common practice of nesting therapists within conditions can pose important methodological challenges that affect interpretation, particularly if the study is not powered to account for the nested design. An obstacle to the optimal design of these studies is the lack of data about the intraclass correlation coefficient (ICC), which measures the statistical dependencies introduced by nesting. To begin the development of a public database of ICC estimates, the authors investigated ICCs for a variety outcomes reported in 20 psychotherapy outcome studies. The magnitude of the 495 ICC estimates varied widely across measures and studies. The authors provide recommendations regarding how to select and aggregate ICC estimates for power calculations and show how researchers can use ICC estimates to choose the number of patients and therapists that will optimize power. Attention to these recommendations will strengthen the validity of inferences drawn from psychotherapy studies that nest therapists within conditions.     

Effect of Pre-test Genetic Counseling for Deaf Adults on Knowledge of Genetic Testing

Empirical data on genetic counseling outcomes in the deaf population are needed to better serve this population. This study was an examination of genetics knowledge before and after culturally and linguistically appropriate pre-test genetic counseling in a diverse deaf adult sample. Individuals ≥18?years old with early-onset sensorineural deafness were offered connexin-26/30 testing and genetic counseling. Participants completed questionnaires containing 10 genetics knowledge items at baseline and following pre-test genetic counseling. The effects of genetic counseling, prior beliefs about etiology, and participant's preferred language on genetics knowledge scores were assessed (n?=?244). Pre-test genetic counseling (p?=?.0007), language (p?相似文献   

The Inaugural Address: Kantian Modality: Tom Baldwin

Kant's claim that modality is a 'category' provides an approach to modality to be contrasted with Lewis's reductive analysis. Lewis's position is unsatisfactory, since it depends on an inherently modal conception of a world. This suggests that modality is 'primitive'; and the Kantian position is a prima facie plausible position of this kind, which is filled out by considering the relationship between modality and inference. This provides a context for comparing the Kantian position with Wright's non-cognitivist 'conventionalism'. Wright's position is vulnerable to the type of argument used against ethical non-cognitivism, and the Kantian position is further confirmed by Blackburn's acknowledgment that modality is 'antinaturalistic to its core'. The position is further elaborated to show that it can accommodate the famous Kripkean categories of the empirically necessary and the contingent a priori , and finally defended against the criticisms used by Quine against Carnap.
