Article
Despite increasing prominence, little is known about the cognitive processes underlying shared decision making. To investigate these processes, we conceptualize shared decision making as a form of distributed cognition. We introduce a Decision Space Model to identify physical and social influences on decision making. Using field observations and in...
Article
An alternative to conventional models that treat decisions as open-loop independent choices is presented. The alterative model is based on observations of work situations such as healthcare, where decisionmaking is more typically a closed-loop, dynamic, problem-solving process. The article suggests five important distinctions between the processes...
Article
Background: While dichotomous tasks and related cognitive strategies have been extensively researched in cognitive psychology, little is known about how primary care practitioners (general practitioners [GPs]) approach ill-defined or polychotomous tasks and how valid or useful their strategies are. Objective: To investigate cognitive strategies...
Article
In 1998, Gigerenzer et al. studied how heterosexual men with low-risk behavior were counseled about the accuracy of HIV test results. Most professional counselors conveyed the illusions that false positives do not occur and that a positive HIV test result means that the client is certainly infected. To help improve counseling quality, the authors p...

BACKGROUND Though medical decision making is ostensibly only a task of health professionals, many – if not most – and also critical health related decisions are made by laypersons. For example, the first step to receiving the right health care requires the patient to determine whether and where too seek health care (triage). Overcautious self-asses...

A first impression matters, in particular when encounters are brief as in most doctor-patient interactions. In this study, we investigate how physicians’ body postures impact patients’ first impressions of them and extend previous research by exploring posture effects on the perception of all roles of a physician – not just single aspects such as s...
