Using a priming paradigm for display effectiveness assessment
Résumé
In order to assess the relevance of colour coding of severity in a nuclear control board, a repetition priming measure was adapted. Fourteen operators were presented with a list of alarms taken from their display, and asked either to pay attention to their colour, or to pay attention to their severity. Then they rated the colour of studied and non-studied warnings presented without their colours. When attention was directed to severity, memory for colour was as good as when attention was directed to colour, this result indicated that colour was processed when processing severity. Repetition priming allows one to partial out memory performance into two components: that due to reconstruction based on domain knowledge, and that due to pure memory for the information presented earlier. In addition, it offers several advantages over classical measures of memory for industrial settings.
