Question and answer
What kinds of visual aids are used in health care and how do they enhance communication?
Recent research has shown that patients frequently experience difficulties understanding health-relevant numerical concepts. [ A prominent example is denominator neglect, or the tendency to pay too much attention to numerators in ratios (e.g., number of treated patients who died) with insufficient attention to denominators (e.g., overall number of treated patients). Denominator neglect can lead
to inaccurate assessments of treatment risk reduction and thus can have important consequences for decisions about health. Here, we reviewed a series of studies investigating (1) different factors that can influence patients' susceptibility to denominator neglect in medical decision making—including numerical or language-related abilities; (2) the extent to which denominator neglect can be attenuated by using visual aids; and (3) a factor that moderates the effectiveness of such aids (i.e., graph literacy). The review spans probabilistic national U.S. and German samples, as well as immigrant (i.e., Polish people living in the United Kingdom) and undergraduate samples in Spain. Theoretical and prescriptive implications are discussed. ]

What kinds of visual aids are used in health care and how do they enhance communication?
Weegy: Visual aids have been in use since the first cave drawings when stick figures illustrated hunts and herd migrations. They were so effective that scientists can still understand them today. [ [ [ This is still relevant in business, school, and personal presentations. Audio and visual aids can be created from a wide variety of sources, and using them aids a listener by providing a visual stimulation, and illustrating concepts makes them easier to understand and follow, thus improving the communication of thoughts and ideas. ] ] (More)
