Processing Speed

The pace at which a child takes in, makes sense of and responds to information — and why slower doesn't mean less capable.

Written for families

Plain English, no jargon. You don't need a teaching background to use this — just read the parts that feel useful and skip the rest. If something raises a question, your child's teacher or SENDCO is the best next step.

Practical ideas to try

Give thinking time

Ask, then wait — count silently to ten. Their answer is on its way.

Reduce pace where you can

Morning routines with visual timers, homework with pause points, dinner with a turn-taking rhythm.

Prewarn topics

"I'm going to ask you about your day in a minute" gives them time to prepare an answer.

Protect rest

A day of trying to keep up is exhausting. Recovery time after school isn't laziness — it's necessary.

Cognitive Load

Why this is relevant

Cognitive load and processing speed compound: heavier tasks feel heavier still when the pace is slower.
