Bechara Gambling Task
2021年10月30日Register here: http://gg.gg/wdbfg
Using an experimental paradigm, the gambling task, which simulates real-life situations in the way it factors uncer- tainty, reward, and punishment (Bechara et al., 1994), VM sub. Iowa Gambling Task (IGT): A software version of IGT was prepared based on original IGT used by Bechara et al. (Bechara et al., 1994, 2000). The frequency of reward/penalty and magnitude were kept same as used in the original IGT. However, a minor change was made in the IGT used for this study. The Bechara simulated gambling task is a popular method of examining decision-making deficits exhibited by people with brain damage, psychopathology, antisocial personality, or drug abuse problems. However, performance on this task is confounded by complex interdependencies between cognitive, motivational, and response processes, making it difficult to sort out and identify the specific. THE IOWA GAMBLING TASK. The IGT (Bechara et al., 1994) has become the key experimental paradigm in evaluation of emotion-based decision-making, especially when humans are faced with emotion-mediated information, ambiguous contingencies, and uncertain consequences (e.g., Rogers et al., 1999; Manes et al., 2002; Bowman and Turnbull, 2004; Happaney et al., 2004). This task is based on Bechara et al’s so-called ’Iowa Gambling task’ In this procedure, subjects are given $2000 to begin. On each trial, they are given the choice of four decks, and after each card, they are given a reward of some amount; after some cards, they are given a reward and pay a penalty.

This task is based on Bechara et al’s so-called ’Iowa Gambling task’ In this procedure, subjects are given $2000 to begin. On each trial, they are given the choice of four decks,and after each card, they are given a reward of some amount; after some cards, they are givena reward and pay a penalty.NotesThe penalty/reward structure is identical to that in Bechara et al.with 40 cards per deck, and the identical reward structure.When 100 cards have been selected, the task is complete. Unlike the real-world version, the deck is just rotated on each draw, so that the top card moves to the bottom of the 40-card deck,and so the sequence will repeat after 40 cards in the original order, rather than becoming exhausted after 40 draws.Options* By default, the penalty cards are in the order originally published by Bechara et al. Setting ’shuffleDecks’ <- 1 (from 0) will shuffle the penalty decks before the experiment. Shuffling is performed in 10-card epochs, so that the penalty in 1-10 stay in 1-10, etc.*Baseline rewards for each deck can be changed as well, using ’the deck1Rew’, ’deck2Rew’, ’deck3Rew’, and ’deck4Rew’ variables.*The variable ’gUseMouse’ controls whether interaction is done using the mouse or keyboard input. Set to 0 for keyboard, 1 for mouse. It is 1 by default.*The variable ’numtrials’ controls how many trials are used. Cards in decks get rotated from top to bottom, so there is no great danger of running out of cards.Data OutputData are saved to igt-X.txt, where X is the participant code. The columns are: participant_code trial deck reward penalty net total_reward absolute_time rtEach row is a trial. You are probably most interested in the proportion that each deck is chosen, which is the third column.ReferencesBechara A, Damasio A. R., Damasio H, & Anderson S. W. (1994).
