We examined whether discrete trial training (DTT) could be used to identify learning impairments in mathematical reasoning in boys with fragile X syndrome (FXS). Boys with FXS, aged 10-23 years, and age and IQ-matched controls, were trained to match fractions to pie-charts and pie-charts to decimals either on a computer or with a trained behavior analyst using DTT. Participants with FXS obtained significantly lower learning rates on the fractions to pie-charts task, and were more likely to perseverate on previously reinforced responses during learning compared to controls. These data suggest that DTT can be used to identify specific learning impairments in boys with FXS, as well as other low-functioning individuals with developmental disabilities.
我们研究了离散试验训练（DTT）是否可用于识别脆性X综合征（FXS）男孩在数学推理方面的学习障碍。对年龄在10至23岁的FXS男孩以及年龄和智商匹配的对照组，通过DTT在计算机上或由经过培训的行为分析师指导下，训练他们将分数与饼图匹配以及将饼图与小数匹配。与对照组相比，患有FXS的参与者在分数与饼图任务上的学习率显著更低，并且在学习过程中更有可能执着于先前得到强化的反应。这些数据表明，DTT可用于识别患有FXS的男孩以及其他低功能发育障碍个体的特定学习障碍。
