“…Varios estudios han intentado determinar que variables explican este fenómeno (van den Bos et al, 2006;Lin et al, 2009;Lin et al, 2007). A este mazo le corresponden ganancias continuas y pérdidas poco frecuentes (una pérdida de 1250 euros en cada 10 elecciones), por lo que la preferencia por este mazo puede ser debida a la frecuencia de ganancias y pérdidas, y no a los resultados obtenidos a largo plazo (Lin et al, 2007).…”

“…En esta prueba se presentan al sujeto cuatro mazos de cartas; todas las cartas dan dinero, si bien unas dan más que otras (algunas cartas tras entregar dinero también pueden sustraer cantidades determinadas del mismo). Para ejecutar adecuadamente esta prueba, el sujeto debe seleccionar cartas de los mazos con menores ganancias, pero también con menores pérdidas (mazos favorables), y obviar aquellos mazos en los que las ganancias son elevadas pero las penalizaciones también (Balodis, MacDonald y Olmstead, 2006;van den Bos, Houx, y Spruijt, 2006;DeDonno y Demaree, 2008;Dunn, Dalgleis y Lawrence, 2006;Fernie y Tunney, 2006;Lin, Chiu y Huang, 2009;Lin, Chiu, Lee y Hsieh, 2007).…”

“…Los sujetos normales, antes de aprender cuales son los mazos más favorables adquieren una sensación positiva hacia éstos y una sensación negativa hacia los mazos desfavorables (van den Bos et al, 2006;Dunn, Dalgleis y Lawrence, 2006;Gordillo et al 2010;Lin et al, 2009;Lin et al, 2007;Verdejo y Bechara, 2010). Los sujetos con alteración en la toma de decisiones fracasarían en la ejecución de esta prueba al no captar dicha información.…”

Introduction. The somatic marker hypothesis proposes that certain body signals guide decision-making processes in an adaptive direction. To see the influence of these markers on decision-making we used the Iowa Gambling Task, through which several studies have shown impaired decision-making in drug-dependent patients. Objective. To assess the performance of a sample of drug-dependent patients in a task that is sensitive to the measurement of decision-making process, so as to see whether there are significant alterations, and to compare the performance of these patients with that of non-users (in the normal and inverted versions). Method. The sample consisted of 66 people (33 addicts and 33 control participants). We used a semi-structured interview on socio-demographic variables and two versions of the "Cartas" task, a computerised version of the Iowa Gambling Task. Result. Significant differences were found between the control and experimental groups in execution of the normal task, but not of the inverted version. In total, 75.76% of the drug-dependent patients showed impaired task performance, as against 24.24% who performed it correctly. Discussion. The results indicate the presence of alterations in the decision-making processes of drug-dependent patients, who did not perform as well as the control group. This may be due to difficulty in generating somatic states according to possible future consequences (myopia about the future) in patients addicted to drugs.Key Words: Somatic marker, decision-making, drug addictions, "Cartas" software. RESUMEN ABSTRACTIntroducción. La hipótesis del marcador somático propone que existen señales corporales que guían los procesos de toma de decisiones en un sentido adaptativo para el organismo. Para ver la influencia de estos marcadores sobre la toma de decisiones se ha utilizado la prueba "Iowa Gambling Task", la cual se ha comprobado su alta sensibilidad a deterioros en la toma de decisiones de pacientes drogodependientes. Objetivo. Valorar el rendimiento de una muestra de pacientes drogodependientes en una tarea sensible a la medición del proceso de toma de decisiones, para ver si existen alteraciones significativas, y comparar el rendimiento de estos pacientes con el de personas no consumidoras (en la versión normal e invertida). Método. La muestra estaba formada por 66 personas (33 drogodependientes y 33 participantes controles). Se utilizó una entrevista semiestructurada sobre variables sociodemográficas y dos versiones de la tarea "Cartas", versión computerizada de la Iowa Gambling Task. Resultados. Se dan diferencias significativas entre el grupo control y experimental en la ejecución de la tarea normal pero no en la inversa. El 75,76% de los pacientes drogodependientes presentan deterioro en la ejecución de la tarea frente a un 24,24% que la realizan de forma adecuada. Discusión. Los resultados indican la presencia de alteraciones en los procesos de toma de decisiones de los pacientes drogodependientes, mostrando éstos un rendimiento menor que el grupo control. Esto ...

RESUMO -O Iowa Gambling Task (IGT) é uma tarefa amplamente utilizada na avaliação da capacidade de tomada de decisão. Neste artigo, procede-se à revisão da literatura, comparando-se as versões do IGT, as diferentes medidas de avaliação do desempenho e as alterações introduzidas nos procedimentos, nomeadamente no feedback, na aleatorização espacial dos baralhos, no número de ensaios e de cartas por baralho, nas instruções, na remuneração e na manipulação das recompensas e punições. Desta análise, conclui-se que as diversas versões da tarefa, as alterações nos procedimentos de aplicação e as diferentes medidas utilizadas na avaliação têm impacto no desempenho, prejudicam a comparação entre estudos e as generalizações dos resultados. Finalmente, apresentam-se sugestões para uma maior adequação dos procedimentos. Palavras-chave: Iowa Gambling Task, tomada de decisão, feedback, recompensas, puniçõesThe Iowa Gambling Task: A Critical Revision ABSTRACT -The Iowa Gambling Task (IGT) is a widely used task in the assessment of the decision-making ability. In this article, we conduct a literature review by comparing IGT versions, different performance assessment measures, and changes to procedures including feedback, spatial randomization of decks, number of trials, number of cards per deck, instructions, payment, and rewards and punishments. On basis of this analysis, we conclude that different versions of the task, changes in application procedures and different measures used to assess the task have an impact on performance, thereby affecting comparison among studies and generalization of results. Finally, we offer suggestions to define adequate procedures.

“…Some investigations have indicated confounding factors affecting the performance of different cultural groups on the task, but still unclear is whether these differences are related to cultural variables. For example, one study found that normal Taiwanese subjects prefer cards from deck "B" and dislike cards from deck "C" of the IGT Lin, Chiu, Lee, & Hsieh, 2007). Therefore, more research needs to be conducted to investigate the influence of cultural and sociodemographic factors on individuals' performance on this task.…”

This study compared the performance of selected groups of Brazilian and American individuals on the Iowa Gambling Task (IGT). The sample was composed of 70 Brazilian and American individuals of both genders, divided into two groups of young and older adults. The two groups of Brazilians were composed of 10 young adults, aged 25 to 41 years, and 25 older adults, aged 60 to 75 years. The two groups of Americans were composed of 10 young adults, aged 28 to 39 years, and 25 older adults, aged 60 to 76 years. A two-way analysis of variance revealed differences in performance between Brazilian and American participants, regardless of age group (country, p = .001; age group, p = .134; country vs. age group, p = .291). Analyses of variance using age group and country as main factors did not reveal any difference between the two national groups with regard to the learning achieved during the task (block, p < .001; age group, p = .063; country, p = .086). The results suggest that culture, represented by the country of origin, influences the performance of individuals on the IGT, demonstrating the importance of validating an instrument for each cultural group on which it is used.
