From: Immediate gain is long-term loss: Are there foresighted decision makers in the Iowa Gambling Task?

Figure 4

Subject memory assessment in the Soochow Gambling Task. Forty-eight subjects were required to report their behavior and preferences after completion of the game. (4A) Most of the sample (36 subjects) had vivid impressions for high-frequency gain decks (A+B) (x2 (1) = 12.00, p < .01), (4B) but not high-frequency loss (C+D) (x2 (1) = 0.00, p = 1.00). (4C) Additionally, most subjects (31 subjects recognized decks A and B) possessed a clear (but wrong) image for the overall monetary gain (x2 (1) = 4.08, p < .05); (4D) but a blurred image for overall monetary loss (x2 (1) = .08, p = .77). (4E) After completing the game, subjects erroneously equated the high-frequency gains as the overall advantage. Thirty one out of forty eight subjects indicated the favorable choice to decks A and B rather than C and D (x2 (1) = 4.08, p < .05). (4F) Most unfavorable choice they had memorized were decks C and D which possessed the high-frequency loss and positive expected value (x2 (1) = 8.33, p < .01).
