There are now a few studies that have examined whether videogames might be able to help in the treatment of another special needs group - children with impulsive and attentional difficulties. Kappes21 tried to reduce impulsivity in incarcerated juveniles (ages 15 to 18 years) by providing either biofeedback or experience with a videogame. Impulsivity scores improved for both conditions. Improvement was also noted in negative self-attributions and in internal locus of control. The authors concluded that most likely explanation for the improvement in both experimental conditions was the immediate feedback. Clarke22 also used videogames to help adolescents learn impulse control. A videogame was used for four week swith four subjects(11to17years)diagnosed with impulse control problems. After the experimental trial, the participants became more enthusiastic and co-operative about treatment.
