Differential monetary gains and losses and event probability in a two-choice situation.

On Learning To Become a Successful Loser: A Comparison of Alternative Abstractions of Learning Processes in the Loss Domain

“…They hypothesized that this effect is a result of the magnitude of the difference between G and B and proposed a subjective expected utility explanation. However, a subsequent study (Myers et al, 1963) failed to support this explanation. Myers et al found that a multiplication of all payoffs by 10 has only a small effect on the learning speed.…”

What does and does not alleviate base-rate neglect under direct experience

“…The answer probably lies in the slowness of improvement with extended practice. After 288 trials, overshooting is 0.03 (Friedman et al, 1964); after 400 trials it averages 0.05 (Myers et al, 1963); after 450 trials it is 0.08 (Gardner, 1957), though this was obtained with three choice alternatives, a manipulation that was found to increase overshooting systematically (Gardner, 1958). After 1000 trials, overshooting averages 12.6% (Edwards, 1961).…”

Factorial effects in the categorization of externally distributed stimulus samples

“…Such an improvement has been found a number of times for binary prediction tasks (Siegal & Goldstein, 1959;Myers, Fort, Katz, & Suydam, 1963), and the present task can be thought of as a set of simultaneous binary prediction tasks, each task being cued by a stimulus value of the continuum. In psychophysics, Swets & Sewall (1963) found that there was some improvement in a detection task with added monetary motivation, and refer to other similar findings.…”
