Abstract
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 IQmatched controls were trained to match fractions to piecharts and piecharts 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 piecharts 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 lowfunctioning individuals with developmental disabilitiesWe would like to thank the children and families for taking part in this study This research was supported by Award Number K08MH081998 PI Scott Hall from the National Institute of Mental Health and by a clinical grant from the National Fragile X Foundation PI Scott Hall
