“…Improvement in sensitivity to task-relevant information and reduction in attention to irrelevant information with instruction and practice should make some variables more informative and sume less misinformative. In support of these general principles, the Interest in the problem of effects of immediately preceding event variables on sensitivity to change in self motion arose from two sources: (a) our own studies of sensitivity to change in the speed of one's own motion (Owen, Warren, Jensen, Mangold, & Hettinger, 1981;Owen, Wolpert, & Warren, 1984;Tobias & Owen, 1984;Warren, Owen, & Hettinger, 1982) and to differences in direction, particularly distinguishing loss in altitude from level flight (Hettinger, Owen, & Warren, 1985;Wolpert & Owen, 1985;Wolpert, Owen, & Warren, 1983); and (b) the work of Denton (1973Denton ( , 1974Denton ( , 1976Denton ( , 1977) on adaptation to forward speed during driving.…”

This report includes three experiment sections. The first experiment tested sensitivity to loss in altitude and demonstrated that: (1) preview effects led to adaptation; (2) sensitivity decreased with higher flow rates; and (3) sensitivity increased with higher optical texture densities and fractional loss. The second and third experiments examined the perception and control of change in forward speed and altitude, respectively. Results from the former indicated that higher levels of fractional loss led to enhanced control of a constant speed, whereas high flow and/or edge rates interfered with performance. The control of altitude change was similarly affected by the levels of fractional loss, but the negative effect of flow rate occurred only in conditions of descending flight. Theoretical implications for the ecological approach to the study of perception and control are discussed. (Author)

“…In contrast, descent-detection accuracy improved by only a few percentage points over durations of 2, 4, and 8 s . Denton (1973Denton ( , 1974Denton ( , 1976 found a quite different effect of longerterm exposure to the flow pattern; namely, that some individuals adapt to self-motion stimulation.…”
