Over half of the undergraduate students entering physiology hold a misconception concerning how breathing pattern changes when minute ventilation increases. Repair of this misconception was used as a measure to compare the impact of three student laboratory protocols on learning by 696 undergraduate students at 5 institutions. Students were tested for the presence of the misconception before an...
Causal composition allows people to generate new causal relations by combining existing causal knowledge. We introduce a new computational model of such reasoning, the force theory, which holds that people compose causal relations by simulating the processes that join forces in the world, and compare this theory with the mental model theory (Khemlani et al., 2014) and the causal model theory (S...
Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues....
Nine experiments examined whether individuals treat the meaning of basic conditional assertions as deterministic or probabilistic. In Experiments 1-4, participants were presented with either probabilistic or deterministic relations, which they had to describe with a conditional. These experiments consistently showed that people tend only to use the basic if p then q construction to describe det...
Assumptions constrain the vision and ability of health care systems throughout the world to achieve unprecedented levels of performance. Leaders who want to accelerate improvement should themselves question these assumptions and provide a context in which others can do so. Six current assumptions are particularly troublesome and particularly worthy of careful reconsideration: (i) that future pe...
Spatial abilities-defined broadly as the capacity to manipulate mental representations of objects and the relations between them-have been studied widely, but with little agreement reached concerning their nature or structure. Two major putative spatial abilities are "mental rotation" (rotating mental models) and "visualisation" (complex manipulations, such as identifying objects from incomplet...
When people think about what might have been, they undo an outcome by changing events in regular ways. Suppose two contestants could win 1,000 Pounds if they picked the same color card; the first picks black, the second red, and they lose. The temporality effect refers to the tendency to think they would have won if the second player had picked black. Individuals also think that the second play...
BACKGROUND Non-technical skills are seen as an important contributor to reducing adverse events and improving medical management in healthcare teams. Previous research on the effectiveness of teams has suggested that shared mental models facilitate coordination and team performance. The purpose of the study was to investigate whether demonstrated teamwork skills and behaviour indicating shared ...
The aim of this paper is to make a review of studies concerning problems with alarm systems and to make a theoretical analysis of these problems. The aim is also to show some general design ideas to improve alarm presentation in process descriptions. Using research results from situation awareness and decision making a number of suggestions for further development of alarm systems are presented...
Many concepts depend on negation and on relations such as conjunction and disjunction, as in the concept: rich or not democratic. This article reports studies that elucidate the mental representation of such concepts from descriptions of them. It proposes a theory based on mental models, which represent only instances of a concept, and for each instance only those properties, affirmative or neg...
