摘要:Abstract The aim of the present study was to explore the effect of study of miniature on concentration of Iranian children with nonverbal learning disability (NLD). A sample of 20 children (8-10 years) was randomly assigned to experimental and control groups. The experimental group took part in twelve sessions of miniature with 45-60min, while the control group was put on a waiting list. Both groups received the Toulouse-Pieron test three times (pre- test, mid-test, and past-test). The results of ANCOVA based on repeated measure indicated Analyses of variance revealed that Persian miniature had a significant effect on concentration. Results were discussed in terms of miniature as a possible therapeutic method in rising concentration for learning disability children.
