Using a token-actuated timer to reduce television viewing.

A parent built a simple box. The child had to drop a token in to turn on the TV for 30 minutes. Tokens were earned for chores or homework. The study tracked how much TV the child watched each day.

The family collected data for weeks. They kept the timer system in place and checked again later to see if the low TV time stuck.

TV time dropped sharply once the token box arrived. The child chose to watch less because tokens now had other uses. Two follow-ups months later still showed low viewing.

Friedling et al. (1979) tried self-instruction alone with hyperactive kids and saw no gain. When they added tokens, behavior improved. The 1985 timer is the next step: it shows tokens can also cut an unwanted habit like too much TV.

Koop et al. (1983) used tokens to stop stealing in class. Williams et al. (2002) used tokens plus praise to make recess fair. All three single-case studies show the same theme—tokens tied to clear rules change child behavior.

Yakubova et al. (2021) moved the idea into the present. Parents filmed short clips and taught daily-living skills to an autistic teen. Like the 1985 family, parents ran the whole program at home and saw big, lasting gains.

You can build a token timer in one evening. A kitchen timer, a plastic box, and a few poker chips are enough. Use it for TV, video games, or tablet time. Let the child earn tokens with chores, homework, or exercise. The 1985 study shows the setup keeps working after you fade the tokens, so you are not stuck refilling prizes forever. Try it next week and graph the minutes—simple, cheap, and parent-friendly.
