JOURNAL OF EXPERIMENTAL PSYCHOLOGY-HUMAN PERCEPTION AND PERFORMANCE
Perceptual decisions are often made in complex social settings in which dis
tinct observers can affect each other. To address such situations, I. Erev,
D. Gopher, R. Itkin, and Y. Greenshpan (1995) proposed a formal extension
of signal-detection theory and a descriptive modification of the extended t
heory. The current article presents 2 experiments that were designed to tes
t these models in the context of repeated 2-person perceptual safety games.
In both experiments, pairs of participants performed a simulation of an in
dustrial-production process under distinct payoff rules. Each participant h
ad to try to produce as much as possible while avoiding costly accidents. I
n line with the descriptive model's predictions, the results showed a slow
adjustment to the incentive structure that can be approximated by a reinfor
cement learning process among different perceptual cutoff strategies. Provi
ding players with prior information about the game had an initial effect bu
t did not alter the pattern of the results.
