This study examined performance on the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994) as a measure of low-income school-aged children's affective decision-making and considered its utility as a direct indicator of impulsivity. One hundred and ninety-three 8-11 year olds performed a computerized version of the Iowa Gambling Task, a validated measure of decision-making. Multi-level modeling was used to examine children's performance over the course of the task, with age, gender, and teachers' ratings of child impulsivity (BIS-11; Patton, Stanford, & Barratt, 1995) used to predict children's Iowa Gambling performance. Higher impulsivity scores predicted a decrease in slope of Iowa Gambling performance, indicating students rated higher on impulsivity chose more disadvantageously across the task blocks. Results support evidence of the validity of the Iowa Gambling Task as a measure of impulsivity in low-income minority children.
本研究考察了爱荷华赌博任务(IGT;Bechara、Damasio、Damasio和Anderson,1994)的表现,以此作为衡量低收入学龄儿童情感决策的指标,并探讨其作为冲动性直接指标的效用。193名8至11岁儿童完成了爱荷华赌博任务的计算机化版本,这是一种经过验证的决策衡量方法。采用多层次建模来考察儿童在任务过程中的表现,以年龄、性别和教师对儿童冲动性的评分(BIS - 11;Patton、Stanford和Barratt,1995)来预测儿童的爱荷华赌博任务表现。较高的冲动性得分预示着爱荷华赌博任务表现的斜率下降,这表明冲动性评分较高的学生在各个任务块中做出的选择更不利。研究结果支持了爱荷华赌博任务作为衡量低收入少数族裔儿童冲动性有效性的证据。
