Enhancing task performance in adults with intellectual disability through modified goal management training and...

Area of Science:

• Cognitive Rehabilitation
• Intellectual Disabilities Research
• Assistive Technology in Education

Background:

• Individuals with intellectual disabilities often struggle with complex task acquisition.
• Modified Goal Management Training (mGMT) and assistive technology with Errorless Learning (App+EL) are potential interventions.
• The effectiveness of these interventions needs rigorous evaluation.

Purpose of the Study:

• To evaluate the efficacy of mGMT and App+EL in learning complex tasks.
• To assess the retention of learned skills after a second intervention.
• To compare intervention effects against a passive control group.

Main Methods:

• Randomized controlled crossover trial with three groups: mGMT, App+EL, and passive control.
• Interventions involved six 30-minute sessions.
• Performance measured using the Goal Attainment Scale (GAS) on practiced, non-practiced, and previously practiced tasks.
• Neuropsychological tests assessed generalization.

Main Results:

• Both mGMT and App+EL significantly improved performance on practiced tasks compared to controls.
• Intervention sequence influenced the efficacy of the second intervention, but did not impact previously learned tasks.
• Improvements were specifically noted in the Tower of London task.

Conclusions:

• mGMT and App+EL are effective strategies for learning complex tasks in individuals with intellectual disabilities.
• These interventions facilitate skill retention even after learning a subsequent task.
• The findings support the use of targeted training approaches to enhance cognitive abilities.
