Bliss, James P. and McAbee, Patrick E. (1995): Alarm Responses in a Dual-Task Paradigm as a Function of Primary Task Criticality. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 1395-1399.

“Technological advances in visual and auditory alarm systems have enabled these systems to be easily implemented. Frequently, the resulting increase in alarm sensitivity is accompanied by an increase in false alarms, which may have potentially disastrous implications for complex task performance. Previous research has examined the nature of the cry-wolf effect in a dual-task paradigm and noted the influence of alarm criticality on alarm response performance. The goals of this research were to supplement that effort by examining the effect of primary task criticality on alarm responses. Seventy-eight undergraduate students performed the Manikin test from the DELTA battery while being presented alarms, 75% of which were true. A series of oneway ANOVAs assessed the effects of increasing primary task criticality on alarm responses. The results supported our hypotheses, indicating that as primary task criticality increased, participants' responses to alarms were degraded. The results are discussed with regard to human performance theories.”
