Case method and casuistry: The problem of bias

Case methods of reasoning are persuasive, but we need to address problems of bias in order to use them to reach morally justifiable conclusions. A bias is an unwarranted inclination or a special perspective that disposes us to mistaken or one-sided judgments. The potential for bias arises at each stage of a case method of reasoning including in describing, framing, selecting and comparing of cases and paradigms. A problem of bias occurs because to identify the relevant features for such purposes, we must use general views about what is relevant; but some of our general views are biased, both in the sense of being unwarranted inclinations and in the sense that they are one of many viable perspectives. This reliance upon general views to determine relevancy creates additional difficulties for defenders who maintain that case methods of moral reasoning are not only useful, but more basic, reliable or prior to other forms of moral reasoning. If we cannot identify the case's relevant features and issues independently of our general views or biases, we need further explanation about why a case method or casuistry should be viewed as prior to or more basic or reliable than other forms of moral reasoning. Problems of bias also arise for other methods of reasoning. In medical science, case reviews are regarded as an unreliable way to form generalizations, and methods such as clinical trials are used to address bias.     

Mental health treatment and medical utilization: First pilot study in the military

Savings in medical utilization, as a function of psychotherapeutic intervention, which has been widely demonstrated elsewhere, can be replicated in military medical settings. Results point not only to decreased medical utilization following mental health intervention, but also to more appropriate treatment.The material herein should in no way be construed as reflecting the views or opinions of the Department of Defense or the United States Air Force.     

When is enough enough? We are only beginning

Sheridan (1995) presents the problem of the psychologist consulting to a medical residency program as an example of the difficulty one experiences in attempting to challenge, even from a data-based perspective, the calcification inherent in health systems and medical education in particular. This paper responds to her challenging questions, “How much should we get involved in changing health care and medical education, and at what level (local, national) should psychology intervene (if at all)?” It is suggested that psychologists pick up the challenge to bring about change, whenever possible, with the admonition—we are only beginning.     

Correlates of Regimen Adherence in Cystic Fibrosis

The present investigation studied psychological and familial factors associated with self-care adherence in a sample of 50 children (ages 9 to 17 years) with cystic fibrosis (CF). Children and their parents were recruited through an outpatient pediatric pulmonary medicine clinic at a metropolitan children's hospital. Participants were interviewed and administered measures of family behavior and child psychological variables. Regimen adherence was measured using a telephone interview approach across three occasions per participant. Hierarchical multiple regression with age, perceived family behaviors, health locus of control, and self-competency as predictors, accounted for 53.8% of the variance in regimen adherence. Findings suggest that higher self-esteem and younger age are related to higher rates of regimen adherence among children with CF.     

Ethics and Imagination

Cognitive semantics has made important empirical findings about human conceptualization. In this paper some findings concerning moral concepts are analyzed and their implications for medical ethics discussed. The key idea is that morality has to do with metaphors and imagination rather than with well-defined concepts and deduction. It is argued that normative medical ethics to be psychologically realistic should take these findings seriously. This means that an imaginative casuistry is to be preferred compared to principlism and to other forms of casuistry. Furthermore, the metaphorical character of central principles in medical ethics such as autonomy, utility, justice, and integrity is indicated. Such principles are interpreted as rules of thumb summarizing the collective wisdom concerning prototype cases.     

通道呈现方式与感知学习风格的匹配性对粤-普双言切换代价的影响

选取不同感知学习风格的熟练粤-普双言者被试, 比较在不同通道呈现方式下他们刺激命名任务的表现, 由此考察感知学习风格与通道呈现方式的匹配性对熟练双言者双言切换代价的影响。结果发现, 被试在视觉线索呈现条件下要比在听觉线索条件下的切换代价小; 当感知学习风格与通道呈现方式匹配时, 双言切换代价更低。表明感知学习风格与通道呈现方式的匹配性对于双言切换代价有调节作用。     

Driver trust in and training for advanced driver assistance systems in Real-World driving

Two-hundred and twenty-three participants completed an online survey regarding their experiences with advanced driver assistance systems (ADAS) on their personal vehicles, with focus on 1) drivers’ trust in 13 ADAS technologies, and 2) perceived effectiveness of currently used methods of training. Eighteen drivers participated in focus groups designed to probe more deeply into survey responses. Results of the survey showed that participant ratings of trust increased significantly with longer vehicle ownership, but participants who experienced unexpected ADAS technology behavior rated their trust over time significantly lower on ADAS technologies with the exception of rear collision avoidance. The majority (75.8%) of participants reported receiving some ADAS instruction at their vehicle dealership, but only 16.6% indicated it was formal. Participants who received formalized training reported it to be significantly more effective than those who received informal overviews of their systems. Use of trial and error and the owner’s manual were the most frequently reported methods of learning outside of dealership training. Responses indicated that the lack of content tailored to trim-specific vehicle features in owner’s manuals was a barrier to effective use.
