Autism & Developmental

A computer-based interactive game to train persons with cognitive impairments to perform recycling tasks independently.

Chang et al. (2014) · Research in developmental disabilities 2014
★ The Verdict

A custom computer game with instant feedback taught three adults with intellectual disability to recycle correctly and the skill lasted.

01Research in Context

01

What this study did

Chang et al. (2014) built a simple computer game that teaches recycling. Players drag virtual items to the correct bin. The game beeps right away if they make a mistake.

Three adults with intellectual disability played the game first. Later they practiced with real trash and bins. The team tracked how often each person put items in the right bin without help.

02

What they found

All three adults learned to recycle correctly after the game training. They kept the skill weeks later with no extra teaching.

The game’s instant feedback helped them fix errors fast. Real-world bins looked different, but the skill still transferred.

03

How this fits with other research

Rutherford et al. (2007) used a virtual world game to teach fire and street safety to kids with fetal alcohol spectrum disorders. Both studies show a short game can teach life skills to people with cognitive impairments.

Craddock et al. (1994) taught handwriting to adults with severe ID using a computer. Their success foreshadows the recycling game, proving computers can deliver vocational skills decades ago.

Koegel et al. (1992) added real workplace rehearsal to video modeling. Their extra rehearsal step hints that the recycling game might work even better if staff later practice with actual bins on the job site.

04

Why it matters

You can build or buy a cheap feedback game instead of printing flashcards. Adults with ID mastered a green job skill in hours, not weeks. Try pairing the game with a quick in-vivo walk-through to lock the skill in at work.

03Original abstract

This study assessed the possibility of training three people with cognitive impairments using a computer-based interactive game. A game was designed to provide task prompts in recycling scenarios, identify incorrect task steps on the fly, and help users learn to make corrections. Based on a multiple baseline design, the data showed that the three participants considerably increased their target response, which improved their vocational job skills during the intervention phases and enabled them to maintain the acquired job skills after intervention. The practical and developmental implications of the results are discussed.
