Word recognition varies enormously across items. Each thin line is one target word’s looking curve; the dark line is a weighted smooth across items. Switch tabs to follow a single word across every dataset that tested it.

For the cross-dataset view:

• Item variability
• Word across datasets
• Data

Hover to identify items; pick words in the sidebar to highlight them.

Every dataset in the current release that tested this word, filtered by the sidebar’s age range. Curves use each dataset’s own design (carrier phrases, distractors, timing), so differences reflect both development and design.
