Summary of word learning assessment tasks and score types.

Task	Measurement	Instructions to child	Score type	Score description	Correct link required?
Naming	Phonological Recall	[object displayed on screen] “Tell me what this is called.”	Naming accuracy	No. of objects correctly named	Yes
			Naming recall	Total no. of pseudowords recalled	No
			Naming difference	= Naming recall – naming accuracy; represents no. of pseudowords recalled with incorrect links to semantics	No
Listening	Phonological Recognition	“.… Listen carefully and tell me which one is the right name of the picture.” [object displayed on screen; four words played]	Listening accuracy	No. of objects correctly named	Yes
			Phonological error	Selection of the mispronounced pseudoword	Yes
			Semantic error	Selection of correctly pronounced semantic foil	No
			Combined error	Selection of the mispronounced semantic foil	No
Drawing	Semantic Recall (Nonverbal)	“Draw a [pseudoword].”	Drawing accuracy	No. of objects correctly drawn	Yes
			Drawing recall	Total no. of objects recalled	No
			Drawing difference	= Drawing recall – drawing accuracy; represents no. of objects recalled with incorrect links to pseudowords	No
Describing	Semantic Recall (Verbal)	“Tell me everything you know about a [pseudoword].”	Describing accuracy	No. of categories and features correctly recalled	Yes
			Describing recall	Total no. of correct categories and features recalled	No
			Describing difference	= Describing recall – describing accuracy; represents no. of categories and features recalled with incorrect links to pseudowords	No
Finding	Semantic Recognition	[8 objects displayed on screen.] “Find the [pseudoword].”	Finding accuracy	No. of objects correctly identified	Yes

Note. Accuracy scores used in primary analyses are bolded. All scores for the naming, listening, drawing, and finding tasks had a maximum possible value of 8. The describing task all had a maximum possible value of 40.
