A study was conducted to determine how well the display format effects described by Tullis (1983, 1984) and the resulting prediction equations could be generalized to other display situations. Task complexity and visual monitoring load were identified as task variables which could potentially moderate the format effects and, thus, were varied factorially. The current study also sought to extend Tullis's findings to tasks where the use of several pieces of information from predictable display locations is required. In general, the data indicate the need to study Tullis's format dimensions more fully before using his regression equations to evaluate display designs for use outside the task situation in which the equations were developed. Also, subjects were unable to evaluate their performance accurately under alternative display designs. Their evaluations seemed to be determined mostly by the perceived ease with which information was extracted from the display. This outcome should serve as a warning to system designers. That is, empirical human performance research should be conducted when performance is the paramount design criterion and a validated prediction system, such as the one developed by Tullis for search, is not available.

The many large-scale aerospace simulation facilities now available offer considerable potential for the generation of data on human performance that can be used in systems engineering design efforts. To realize this potential requires an understanding of the methodological limitations imposed by the basic characteristics of human performance, the application of efficient organizational techniques, and the development of more efficient techniques of experiment planning, design, and execution.

First Time

We examined the effects of female reproductive status (ovigerous and non-ovigerous) on chimney characteristics and time allocation for surface activities in Uca rosea (Tweedie, 1937) (currently referred to as Tubuca rosea (Tweedie, 1937)). We investigated time spent on feeding, standing, in burrow, surface mating, walking, grooming, and digging of 13 ovigerous and 20 non-ovigerous females of similar-size and measured the diameter, width, and height of their chimneys. Chimneys of ovigerous females were wider and higher than those of non-ovigerous females, but chimney diameters did not differ. Ovigerous females spent less time on feeding and walking, but more time on standing, inside burrows, and mating than non-ovigerous females. Feeding rate/min did not differ between ovigerous and non-ovigerous females. This study reports, for the first time, that reproductive status of females affects chimney characteristics and time allocation for surface activities in U. rosea.
