Relational training protocols based on Relational Frame Theory (RFT) are showing promising results as regards increased intelligence quotient. This study aimed to analyze the effect on intelligence quotient of a fluency and flexibility training protocol based on relations of coordination. Two students from the same school were the study participants. They were randomly assigned the roles of experimental participant (a boy aged 4 years, 1 month) and control participant (a girl aged 3 years, 11 months). The McCarthy´s Aptitudes and Psychomotricity Scale (MSCA) was used to evaluate cognitive and psychomotor development. The 8-hour training protocol was implemented over a 2-month period. The experimental participant showed an increase of more than 1.5 SD in the General Cognitive Index (GCI) of the MSCA (from 106 to 132) whereas the control participant showed a 10-point increase. The experimental participant partly maintained the improvements at the 6-month follow-up. This study provides further empirical evidence of the potential of RFT training for improving cognitive abilities and intelligence.

Key words:
