The paper outlines the role that tacit knowledge plays in what might seem to be an area of knowledge that can be made fully
explicit or codified and which forms a central element of Evidence Based Medicine. Appeal to the role the role of tacit knowledge
in science provides a way to unify the tripartite definition of Evidence Based Medicine given by Sackett et al: the integration
of best research evidence with clinical expertise and patient values. Each of these three elements, crucially including research
evidence, rests on an ineliminable and irreducible notion of uncodified good judgement. 相似文献

Active versus passive processing of biological motion 总被引:4,自引:0,他引:4
Johansson's point-light walker figures remain one of the most powerful and convincing examples of the role that motion can play in the perception of form (Johansson, 1973 Perception & Psychophysics 14 201 - 211; 1975 Scientific American 232(6) 76 - 88). In the current work, we use a dual-task paradigm to explore the role of attention in the processing of such stimuli. In two experiments we find striking differences in the degree to which direction-discrimination performance in point-light walker displays appears to rely on attention. Specifically, we find that performance in displays thought to involve top-down processing, either in time (experiment 1) or space (experiment 2) is adversely affected by dividing attention. In contrast, dividing attention has little effect on performance in displays that allow low-level, bottom-up computations to be carried out. We interpret these results using the active/passive motion distinction introduced by Cavanagh (1991 Spatial Vision 5 303-309). 相似文献

Previous research has shown that when a moving object is occluded prior to collision with another stationary object, observers tend to consistently underestimate the physical/actual time to collision (TTC). We examined whether mislocalization of the initial point of disappearance plays any role in this underestimation. To assess the contribution of mislocalization, we coupled a standard TTC paradigm with a representational-momentum paradigm. Representational momentum refers to the tendency to mislocalize the remembered stopping point of a moving object as being too far forward along an actual or implied path of motion. Using identical displays we found large representational-momentum shifts and consistent underestimation of TTC. When the displays were modified to disambiguate the point of disappearance, representational momentum was absent or significantly reduced and underestimates of TTC were effectively eliminated. These results strongly suggest that the represented point of disappearance is an important factor in TTC estimation and that systematic forward displacement of this point may partially explain frequently observed underestimation. 相似文献

Its controversial past notwithstanding, psychopathy has emerged as one of the most important clinical constructs in the criminal justice and mental health systems. One reason for the surge in theoretical and applied interest in the disorder is the development and widespread adoption of reliable and valid methods for its measurement. The Hare PCL-R provides researchers and clinicians with a common metric for the assessment of psychopathy, and has led to a surge in replicable and meaningful findings relevant to the issue of risk for recidivism and violence, among other things. Most of the research thus far has been based on North American samples of offenders and forensic psychiatric patients. We summarize this research and compare it with findings from several other countries, including England and Sweden. We conclude that the ability of the PCL-R to predict recidivism, violence, and treatment outcome has considerable cross-cultural generalizability, and that the PCL-R and its derivatives play a major role in the understanding and prediction of crime and violence. 相似文献

Prenatal mental illness is a significant public health issue with intergenerational consequences. Caring for Body and Mind in Pregnancy (CBMP) is an Australian, 8-week mindful parenting program. The primary aim of this study was to investigate the effectiveness of CBMP in reducing pregnant women’s levels of depression, anxiety, perinatal depression, perinatal anxiety and stress. The sample consisted of 109 pregnant women at-risk for perinatal depression and anxiety. The mean age of the sample was 33.52 years (SD?=?4.90), ranging from 21 to 45 years. A within group, pre-post research design was used to examine whether CBMP improves participants’ scores on outcome measures. Wilcoxon Signed Rank test results indicated that CBMP significantly reduced depression, anxiety, perinatal depression, perinatal anxiety and general stress scores, while significantly increasing self-compassion and mindfulness with moderate to strong effect sizes. The double mediation hypothesis was supported with self-compassion t (71)?=??2.23, p?<?03, b2?=??1.96, SE?=?88, 95% CI?=??3.71, ?.20, having a stronger influence in reducing perinatal depression than mindfulness t (71)?=??2.68, p?<?.01, b3?=??.07, SE?=?.03, 95% CI?=??.13, ?.02. Further research, using a randomized controlled design with appropriate control conditions, is needed to establish the effectiveness of CBMP in reducing psychological distress amongst pregnant women at risk of developing depression, anxiety or stress. 相似文献

Anorexia nervosa (AN) is perhaps the most lethal mental disorder, in part due to starvation-related health problems, but especially because of high suicide rates. One potential reason for high suicide rates in AN may be that those affected face pain and provocation on many fronts, which may in turn reduce their fear of pain and thereby increase risk for death by suicide. The purpose of the following studies was to explore whether repetitive exposure to painful and destructive behaviors such as vomiting, laxative use, and non-suicidal self-injury (NSSI) was a mechanism that linked AN-binge-purging (ANBP) subtype, as opposed to AN-restricting subtype (ANR), to extreme suicidal behavior. Study 1 utilized a sample of 787 individuals diagnosed with one or the other subtype of AN, and structural equation modeling results supported provocative behaviors as a mechanism linking ANBP to suicidal behavior. A second, unexpected mechanism emerged linking ANR to suicidal behavior via restricting. Study 2, which used a sample of 249 AN patients, replicated these findings, including the second mechanism linking ANR to suicide attempts. Two potential routes to suicidal behavior in AN appear to have been identified: one route through repetitive experience with provocative behaviors for ANBP, and a second for exposure to pain through the starvation of restricting in ANR. 相似文献

Patient and Partner Quality of Life and Psychosocial Adjustment Following Radical Prostatectomy 总被引:2,自引:0,他引:2

We prospectively examined differences in quality of life and psychosocial adjustment in 80 prostate cancer patients and their partners (n = 65) beginning before radical prostatectomy and proceeding across the first year postsurgery. Both members of the couple experienced significant changes associated with the patient's cancer, however their experiences differed in some regards. Patients experienced reprieve from emotional distress and negative affect immediately following surgery despite worsened physical functioning. Partner quality of life and psychosocial adjustment scores were generally more constant from presurgery to postsurgery, with improvements noted 1 year later. For both patients and partners, cancer-specific stress symptoms declined progressively over the year. We also obtained partial support for the effectiveness of a single-session communication intervention on patient social/family wellbeing and partner general stress. Findings have implications for patient and partner adjustment following radical prostatectomy, and attest to the importance of incorporating partner evaluations into psychosocial oncology research. 相似文献

From an anecdotal rumination, the authors make the case for consideration of past reflections, in what they call 'composting', to inspire and enrich new, different and currently ongoing reflective activity and initiatives. 相似文献
