Acceptance of Illness Among Patients Pursuing Transplantation or Left Ventricular Assist Device

Acceptance of illness is related to better mental health among patients with chronic illness; however, this construct has not been evaluated as part of routine transplantation evaluations. The purpose of this study was to create a brief measure of acceptance of illness for patients pursuing organ transplantation and examine how acceptance is related to distress. Retrospective medical record reviews were conducted for 290 patients who completed a routine psychosocial evaluation prior to transplant listing which included the Illness Acceptance Scale (IAS). Internal consistency for the IAS was excellent (Cronbach’s alpha?=?.92). Illness acceptance was negatively correlated with depression, anxiety, and catastrophizing and was not related to health literacy or health numeracy. The IAS is a reliable and valid measure for patients who are pursuing thoracic transplant or left ventricular assist device. Clinicians may want to screen transplant candidates for illness acceptance and refer those with lower levels to psychological interventions.

     

Lifting the Mantle of Protection from Weber’s Presuppositions in His Theory of Bureaucracy

Early reactions to the publication of Harold Garfinkel??s Studies in Ethnomethodology, which have persisted over the passing decades, was that ethnomethodology could not address what sociology deemed to be socially significant matters such as ??power?? and ??the state??. This, however, is not the case. How such matters enter into the practical everyday affairs of members is of equal interest to ethnomethodology when compared to how any matter enters into members?? everyday life, and how they display that. It just does not have more importance. Egon Bittner spelt this out with regard to Weber??s interest in bureaucracy when he reminds sociology that when Weber talked about efficiency he was not referring to an objective standard but as something that is attuned to practical interests as they emerge in the context of everyday life. This paper examines some of the actions and interactions that were encountered in a Governmental Department in one of the European countries. It makes visible how characterisations of bureaucracy such as ??rational??, and ??efficient?? are achieved in the actions and interactions of Department employees, and some of the practices involved in that achievement. Garfinkel, and ethnomethodology in general, are not, in principle, to be found wanting where matters of overarching, primordial interest to sociology are concerned.     

Cross-ethnic assessment of body weight and height on the basis of faces

Previous research has revealed a strong relationship between mere visual facial cues and body weight. They can be exploited to validly judge the weight of the human body. We tested to what extent observers are able to judge body weight and height on the basis of same-ethnicity and different-ethnicity faces. Caucasian and Asian observers saw Caucasian and Asian faces and estimated the person’s weight and height – merely on the basis of greyscale photographs of the face. These height and weight estimates were influenced by ethnocentric specifics of familiar face proportion and face–body relationship. Own-ethnicity weight estimations showed higher accuracy than foreign-ethnicity estimations. Observers ignored the changed base-rate for weight of other-culture faces in a culture-egocentric fashion. Height judgments, in contrast, reflect a higher degree of sophistication. A bias toward the own, familiar body proportion was visible here, especially for Japanese observers—however, the height judgments showed that observers were able to incorporate the other-ethnicity height proportion to some extent.     

Children's and Adults’ Judgments of the Certainty of Deductive Inferences,Inductive Inferences,and Guesses

Children and adults rated their own certainty following inductive inferences, deductive inferences, and guesses. Beginning in kindergarten, participants rated deductions as more certain than weak inductions or guesses. Deductions were rated as more certain than strong inductions beginning in Grade 3, and fourth-grade children and adults differentiated strong inductions, weak inductions, and informed guesses from pure guesses. By Grade 3, participants also gave different types of explanations for their deductions and inductions. These results are discussed in relation to children's concepts of cognitive processes, logical reasoning, and epistemological development.     

Who is looking at me? The cone of gaze widens in social phobia

Gaze direction is an important cue that regulates social interactions and facilitates joint attention. Although humans are very accurate in determining gaze directions in general, they have a surprisingly liberal criterion for the presence of mutual gaze. Using an established psychophysical task that required observers to adjust the eyes of a virtual head to the margins of the area of mutual gaze, we examined whether the resulting cone of gaze is altered in people with social phobia. It turned out that during presence of a second virtual person, the gaze cone's width was specifically enlarged in patients with social phobia as compared to healthy controls. The size of this effect was correlated with the severity of social anxiety. As this effect was found for merely virtual lookers, it seems to be a fundamental mechanism rather than a specific effect related to the fear of being observed and evaluated by others.     

Visual prior entry for foreground figures

Attended stimuli reach perceptual-level processes before unattended stimuli do, a finding that is referred to as visual prior entry. We asked whether a similar effect arises for salient objects (foreground figures) in a visual scene. If prior entry holds for figure—ground perception, targets will be perceived to appear earlier on figures than on grounds. Participants performed a temporal order judgment by reporting the order in which targets appeared. Participants perceived that targets appearing on foreground figures occurred earlier than did those appearing on backgrounds. These findings did not result from a response bias for targets appearing on figures. Most important, when figures and grounds were spatially separated and did not share an edge, no prior-entry effects were observed. Our results suggest that figural regions are available to perceptual-level processes sooner than are grounds.     

Heading backward: Perceived direction of movement in contracting and expanding optical flow fields

Two goals were pursued in an investigation of possible visual sources for directionality judgments of ego-motion. First, J. J. Gibson’s (1950) global radial outflow hypothesis was contrasted with a simple extrapolation strategy. Second, backing-direction judgments capitalizing on the informational equivalence of global radial outflow created during forward ego-motion and global radial inflow during backward ego-motion were explored. In comparing the accuracy of heading and backing judgments, new insights about global flow and extrapolation strategies were found. Consistent with the hypothesis of an extrapolation strategy, Experiment 1 demonstrated that backing judgments were more accurate than heading judgments when linear observer motion was simulated by means of a point-light flow field. In this case, accuracy was higher with two-point-light displays (extrapolation) than with more complex displays (global flow). Experiment 2 showed that in cases where extrapolation was not possible, such as circular motion, no advantage of backing judgments could be found and judgments were generally less accurate. We conclude that, whenever possible, observers use extrapolation to determine their heading/backing. Only when global flow is the only good source of information do they rely on it.     

The communicative process of drug resistance among high school students.

This article reports the results of the second of two studies designed to examine social influences on adolescents' responses to drug offers. In the first study, a typology of both drug offers and drug resistance strategies was developed. The present study provides an analysis of the associations between offers and resistance and the differences between drug and alcohol offers. To accomplish this, sixty-nine narrative accounts of both successful and unsuccessful attempts to say no were collected from high school students. Analysis of the interviews indicated that peer pressure was applied in approximately 70% of the offers; however, much of that pressure was applied after the initial offer had been refused. It also was determined that simple offers were more likely with alcohol, while drug offers were more likely to be persuasive and involve pressure during the initial offer.     

Apparent extended body motions in depth.

Five experiments were designed to investigate the influence of three-dimensional (3-D) orientation change on apparent motion. Projections of an orientation-specific 3-D object were sequentially flashed in different locations and at different orientations. Such an occurrence could be resolved by perceiving a rotational motion in depth around an axis external to the object. Consistent with this proposal, it was found that observers perceived curved paths in depth. Although the magnitude of perceived trajectory curvature often fell short of that required for rotational motions in depth (3-D circularity), judgments of the slant of the virtual plane on which apparent motions occurred were quite close to the predictions of a model that proposes circular paths in depth.     

Microcomputer graphics in psychological research

This paper discusses a methodology for psychological instrumentation in which requirements common to a spectrum of experiments are defined and implemented in a microcomputer system. The microcomputer may either stand alone or be used as an intelligent front end to a larger computer. In either case, experiments are described in a high-level implementation language. The advantages of this approach include reduced hardware and maintenance costs, increased reliability, and smoother operation by research personnel. A tutorial example is given of the design and construction of one such system used to present visual stimuli, including text, graphics, and simple animation, on a movable array of video monitors. Displays are produced by a Z80 microcomputer in response to commands from a larger host computer, in this case a PDP Lab/8e. Illustrations are given of three studies in progress; comparisons are made with special-purpose equipment built earlier. The microcomputer system is preferable from both a cost and management point of view.
