Too much to juggle

Cognitive load is the demand a task places on working memory: the information you hold and work with right now. Cognitive overload happens when that demand exceeds what you can manage.

Imagine learning a biscuit recipe while remembering the oven setting, three quantities and whether you already added the sugar. The bowl has room. Your mental juggling act may not.

A temporary workspace

The NSW Department of Education explains that working memory holds and processes small amounts of information for a short time.

Long-term memory is different: it stores knowledge you can bring back later. A familiar recipe and a completely new one therefore need not make the same demands. What you already know matters.

Same biscuits, clearer instructions

Compare scattered quantities and instructions with a recipe that puts each amount beside the step where you need it. You still make the same biscuits, but have less searching and remembering to do.

The department’s cognitive load guide recommends removing inessential information and presenting essential information together. It also recommends studying worked examples when learning something new.

Keep the next step visible

For your next unfamiliar task, try keeping the current instruction and the information it needs together. Give your attention a clear next step. Even the sugar can wait its turn.
