Reinforcement 101: Why Praise Alone Doesn't Work

"Good job!" isn't reinforcement unless the child cares about your approval. For many autistic children, social praise has limited motivating value — at least initially. That's not a character flaw. It's a difference in what's reinforcing.

Reinforcement = anything that increases the future probability of a behavior

If praise makes the behavior more likely, it's reinforcing. If it doesn't, it's not — regardless of your intention.

Finding your child's reinforcers

Observe, don't assume. Common motivators for autistic children:

• Specific sensory experiences (deep pressure, certain textures, specific sounds)
• Access to a preferred item (iPad, specific toy, specific food)
• Time doing a preferred activity (trampolining, building blocks, watching specific videos)
• Predictability itself (knowing what happens next)
• Specific praise about specific things (not "good job" but "you waited so patiently while I talked — that was really hard and you did it")

Rules for effective reinforcement

1. Immediate — within 2–3 seconds of the desired behavior. Delay kills the connection.
2. Contingent — only given for the target behavior, not for other reasons
3. Valued by the child — if they don't want it, it won't work
4. Varied — the same reinforcer loses value with repetition (called satiation)

The Premack principle ("Grandma's rule")

High-probability behaviors reinforce low-probability behaviors. "First homework, then iPad." The iPad isn't a bribe — it's a scheduled reinforcer contingent on completing work.

What about intrinsic motivation?

It develops after extrinsic reinforcement builds fluency. You don't teach a child to ride a bike by withholding training wheels and hoping intrinsic motivation kicks in. You scaffold, then fade.
