Brown, Megan L., Newsome, Sandra L. and Glinert, Ephraim P. (1989): An Experiment into the Use of Auditory Cues to Reduce Visual Workload. In: Bice, Ken and Lewis, Clayton H. (eds.) Proceedings of the ACM CHI 89 Human Factors in Computing Systems Conference April 30 - June 4, 1989, Austin, Texas. pp. 339-346.

“The potential utility of dividing the information flowing from computer to human among several sensory modalities is investigated by means of a rigorous experiment which compares the effectiveness of auditory and visual cues in the performance of a visual search task. The results indicate that a complex auditory cue can be used to replace cues traditionally presented in the visual modality. Implications for the design of multimodal workstations are discussed.”

Lamberti, Donna M. and Newsome, Sandra L. (1989): Presenting Abstract versus Concrete Information in Expert Systems: What is the Impact on User Performance?. In International Journal of Man-Machine Studies, 31 (1) pp. 27-45.

“Conceptual differences between experts and novices in problem representation (abstract vs concrete) provided a criterion for evaluating performance on an expert system used for diagnostic problem-solving. In a field study, employee skill level (high vs low), system usage (use of system vs no usage), and question type (requiring abstract vs concrete information organization) were studied with respect to employee performance (speed and accuracy). The findings showed that high-skill employees answered abstract as well as concrete questions faster and more accurately than did low-skill employees. Also, high-skill employees performed significantly faster on questions requiring abstract information organization than concrete information organization. In contrast, low-skill employees performed significantly faster and more accurately on questions requiring concrete information organization as compared to abstract information organization. The data also showed that problem solution time for low-skill employees decreased a greater amount than for the high-skill employees, using the system as compared to not using it. The findings suggest that high and low-skill employees organized their conceptual knowledge about the problem differently. The presentation of information in a manner that is conducive to employees' conceptual representations of a problem is discussed along with directions for future research.”

Newsome, Sandra L. and Hochlerin, Michael E. (1989): When "Not" is Not Bad: A Re-Evaluation of the Use of Negatives. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 229-233.

“Previous literature has consistently shown that affirmative messages are understood more quickly and accurately than negative messages and that redundancy facilitates comprehension and response selection. However, it was unclear which of these two variables is the most important in the design of system-status messages that must be understood and acted upon. In our experiment, we compared affirmative and negative system-status messages when negative messages contained a word redundant with the appropriate action. The results indicated that affirmative messages were responded to more quickly and more accurately than negative messages only when the negative messages did not contain a redundant word. Redundant negative messages were more accurate than affirmative non-redundant messages.”
