Modality Effect

Shrink Definition

The modality effect is the finding that people can learn better when information is split across seeing and hearing rather than crammed into one channel. Pairing a visual diagram with a spoken explanation uses both the visual and auditory parts of working memory. This spreads the load and can improve understanding. It's a practical principle for multimedia learning.

Plain language

We can learn better when information is split across seeing and hearing.

Shrink Insight

Two senses can carry more than one overloaded channel.

Why it matters

It guides multimedia design by balancing visual and spoken information. It helps avoid overloading a single channel.

Common misunderstanding

People think putting everything on the screen as text is clearest. Pairing visuals with narration often works better than text plus visuals.

Shrink Perspective

Let the eyes and ears share the load.

Shrink Reflection

Would a slide work better as an image with narration?

Shrink Step

When presenting, pair a visual with spoken words rather than dense on-screen text.

Shrink Minute

Notice whether a slide would work better as an image with narration.

Shrink Takeaway

Split information across senses to ease learning.

Medical boundary

Evidence summary

A well-supported principle in multimedia learning and cognitive load research.
