Centro de Documentacion de Fundación MAPFRE - The Use of contextual cues to improve warning symbol comprehension: making the connection for older adults

Notas: Sumario: This study teased apart the effects of comprehensibility and complexity on older adults' comprehension of warning symbols by manipulating the relevance of additional information in further refining the meaning of the symbol. Symbols were systematically altered such that increased visual complexity (in the form of contextual cues) resulted in increased comprehensibility. One hundred older adults, aged 5071 years, were tested on their comprehension of these symbols before and after training. High comprehensibilitycomplexity symbols were found to be better understood than low- or medium-comprehensibilitycomplexity symbols and the effectiveness of the contextual cues varied as a function of training. Therefore, the nature of additional detail determines whether increased complexity is detrimental or beneficial to older adults' comprehension if the additional details provide cues to knowledge¿, older adults' comprehension improves as a result of the increased complexity. However, some cues may require training in order to be effective.Registros relacionados: En: Ergonomics : the international journal of research and practice in human factors and ergonomics. - Oxon [United Kingdom] : Taylor & Francis, 2010- = ISSN 0014-0139. - 05/08/2013 Volumen 56 Número 8 - agosto 2013 , p. 1264-1279Otras clasificaciones: 875
