“…It was consistent with previous studies that WM played a role in IGT performance ( Hinson et al, 2002 ; Jameson et al, 2004 ; Pecchinenda et al, 2006 ; Bagneux et al, 2013 ). Nevertheless, these results were not consistent with some studies ( Turnbull et al, 2005 ; Gozzi et al, 2011 ). This might be because we used different versions of IGT, and different secondary task were used.…”

Effects of working memory load on uncertain decision-making: evidence from the Iowa Gambling Task

et al. 2015

The Iowa Gambling Task (IGT) simulates uncertain gains and losses in real life situations and thus is a good measure of uncertain decision-making. The role of working memory (WM) in IGT performance still remains unclear. The present study aimed to examine the effect of WM on IGT performance. Three groups of participants matched on gender ratio were randomly assigned to no WM load, low WM load, and high WM load conditions. Initially the three groups did not show significant difference in WM capacity. They finished a modified version of IGT and then their implicit learning effect and explicit cognition on IGT were assessed. Results indicated a linear increasing trend of IGT performance among high WM load, low WM load and no WM load groups; participants in the no WM load and low WM load groups revealed implicit learning effect, while participants in the high WM load group did not; all participants showed explicit cognition on IGT to the same level. These results suggested that participants in the high WM load group showed good explicit cognition to IGT but showed poor performance. This pattern is similar to frontal patients. Further studies should be conducted to explore this issue.

“…Further adaptations were made on the task: first, it was argued that the reward and punishment schedule in the original IGT was too simple ( Gozzi et al, 2011 ). Participants only needed to attend to the value of loss in the task, since the magnitude of wins were fixed (50 or 100) in the task ( Cauffman et al, 2010 ).…”

“…A second line of research tried to apply a load to WM, with the idea that if the IGT requires WM, then taxing WM should lead to less advantageous decision making on the IGT. Two such studies failed to observe an effect of WM load on decision making under normal IGT conditions [ 12 , 13 ], whereas two other studies observed an effect of WM load [ 14 , 15 ]. Moreover, it has been observed that participants realizing an interfering secondary task - supposed to tax WM - during the first 100 trials of the IGT show a lower number of advantageous decisions in the IGT [ 16 ] – while the same interfering task has no effect on decision making after the 100 th trial.…”

The Iowa Gambling Task (IGT) is a sequential learning task in which participants develop a tendency towards advantageous options arising from the outcomes associated with their previous decisions. The role of working memory in this complex task has been largely debated in the literature. On one hand, low working memory resources lead to a decrease in the number of advantageous decisions and make a significant part of participants unable to report explicitly which options are the most profitable. On the other hand, several studies have shown no contribution of working memory to the IGT decision patterns. In order to investigate this apparent incompatibility of results, we used an individual differences approach, which has proven an effective method to investigate the role of working memory in cognition. We compared the IGT decision patterns of participants as a function of their working memory capacity (WMC). As expected, contrary to low WMC participants, high WMC participants developed a tendency towards advantageous decisions. These findings lead us to discuss the role of WMC in decision making tasks.

The effect of cognitive load on reckless gambling, emotional states, and perceived luck

In this experimental study, the effects of cognitive load on reckless gambling were investigated among Japanese undergraduates. Changes in the participants' emotional states and perceived luck while gambling were also investigated. Participants (23 males and 21 females) performed the Game of Dice Task (GDT) consisting of 18 trials; their emotional states and perceived luck were assessed before the first trial and after subsequent trial. Participants in the experimental group were asked to memorize words while playing the GDT, whereas those in the control group were not required to do so. Results indicate that the experimental group gambled more recklessly than the control group while performing the GDT. Furthermore, participants in the experimental group experienced more positive emotions and better perceived luck than the control group. These results suggest that individuals with cognitive load while gambling are likely to interpret their emotional states and perceived luck more favorably and to overestimate the probability of winning. Therefore, these individuals are prone to gambling recklessly.
