In the context of a cockpit traffic display, previous research has shown that bright aircraft symbols
do not preferentially attract attention when compared with dim aircraft symbols. Instead, bright
aircraft appear to make dim targets more difficult to detect. One hypothesis is that this effect
occurs through a form of contrast inhibition that interferes with participants’ ability to detect the
dim target on the first serial search of the displayed symbols and only allows detection on a
subsequent repeated search. The present experiment manipulates symbol brightness within a
display of mixed bright and dim aircraft and examines participants’ eye movements to test this
hypothesis.

The current trend of high resolution display let it be possible to process the 3D images. There are
good potential to develop the 3D display. New technique let the observer need not to wear any
shuttle glasses or split-color glasses. But the left/right eye images are superimposed. At the same
time there are cross-talk problem. So we do some experiments to test the tolerance rate of the
cross-talk of the subject. The images include the natural images, computer drawing images, and
random-dots patterns. The results show that human eye have good tolerance to static images, far
better than the machine can fulfill.

1005.1 Rapid acquisition in concurrent chains: Evidence for a decision model, R.C. Grace,
University of Canterbury, Christchurch, New Zealand
This talk will review evidence that pigeon’s response allocation in concurrent chains can adjust to
rapidly-changing contingencies; that sensitivity to current- and prior-session contingencies
depends on whether or not there is a predictive relationship between those contingencies; and most
importantly, that response allocation conforming to both generalized matching and categorical
discrimination can be obtained in some cases. All of these results can be explained by a decision
model which assumes that preference for an alternative increases after a relatively short delay to
reinforcement, and decreases after a relatively long delay to reinforcement. The model is able to
explain generalized matching and temporal discounting as the aggregate of a “winner take all”
decision process
1005.2 Temporal factors in choice, D.T. Cerutti, J.E.R. Sttadon, Duke University, Durham,

Choice has been theoretically described in terms of response strength and measured in terms of
response rate. This approach has encouraged molar models and neglect of temporal factors. We
