摘要：

Two laboratory experiments compared stack, offset-stack and diagrammatic advance direction signs in terms of threshold visual angle and response time and errors. Signs displayed two, three or five possible exit directions, so there were three levels of complexity within each sign type. Results showed that stack signs can be smaller than offset-stack and diagrammatic signs for the same level of legibility; response time was largely determined by sign complexity; response time to two direction offset-stack signs was significantly less than to other signs; neither sign type nor complexity was related to number of errors, which was very low.
