The user knows: Considering the cognitive contribution of the user in the design of auditory warnings

Abstract

An experiment that investigated effects of modality, warning type, and task demand on warning recognition speed and accuracy is reported. Using the experiment as a specific example, we argue for the importance of considering the cognitive contribution of the user (viz. prior learned associations) in the warning design process. Drawing on semiotics and cognitive psychology, we highlight the indexical nature of so-called auditory icons or natural indicators and argue that the cogniser is an indispensable element in the tripartite nature of signification. © 2009 Springer Berlin Heidelberg.
