Abstract

Visual displays, such as icon arrays and risk ladders, are often used to communicate numerical health information. Number lines improve reasoning with rational numbers but are seldom used in health contexts. College students solved ratio problems related to COVID-19 (e.g., number of deaths and number of cases) in one of four randomly assigned conditions: icon arrays, risk ladders, number lines, or no accompanying visual display. As predicted, number lines facilitated performance on these problems-the number line condition outperformed the other visual display conditions, which did not perform any better than the no visual display condition. In addition, higher performance on the health-related ratio problems was associated with higher COVID-19 worry for oneself and others, higher perceptions of COVID-19 severity, and higher endorsement of intentions to engage in preventive health behaviors, even when controlling for baseline math skills. These findings have important implications for effectively presenting health statistics. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

在帮助成年人解决与健康相关的比率问题方面，数轴比风险阶梯和图标数组更有效。

视觉显示，如图标阵列和风险阶梯，通常用于传达数字健康信息。数轴可以提高对有理数的推理能力，但很少用于卫生领域。大学生在四种随机分配的条件下解决与COVID-19相关的比例问题(例如，死亡人数和病例数):图标阵列、风险阶梯、数轴或没有附带的视觉显示。正如预测的那样，数行促进了这些问题的表现——数行条件优于其他视觉显示条件，而其他视觉显示条件的表现并不比没有视觉显示条件好。此外，在健康相关比例问题上表现越好，与对自己和他人的COVID-19担忧程度越高、对COVID-19严重程度的认知越高、对参与预防性健康行为的意愿的认可程度越高相关，即使在控制了基线数学技能的情况下也是如此。这些发现对有效呈现卫生统计数据具有重要意义。(PsycInfo数据库记录(c) 2023 APA，版权所有)。

期刊介绍： The mission of the Journal of Experimental Psychology: Applied® is to publish original empirical investigations in experimental psychology that bridge practically oriented problems and psychological theory. The journal also publishes research aimed at developing and testing of models of cognitive processing or behavior in applied situations, including laboratory and field settings. Occasionally, review articles are considered for publication if they contribute significantly to important topics within applied experimental psychology. Areas of interest include applications of perception, attention, memory, decision making, reasoning, information processing, problem solving, learning, and skill acquisition.
