Measures of neuropsychological function used in the current study

Domain	Assessment	Subtest	Description
Fluid Reasoning and Executive Functioning	NEPSY-II	Inhibition (INI)	Inhibitory control and impulsivity: measures child’s ability to inhibit previously learned response
	DAS-II	Matrices (M)	Inductive reasoning: measures child’s ability to identify, formulate, and test relationships between features in an abstract figure
	DAS-II	Sequential and Quantitative Reasoning (SQR)	Inductive reasoning: measures child’s perception of sequential patterns in geometric figures and numerical relationships
Language	DAS-II	Verbal Similarities (VS)	Vocabulary and verbal development: measures a child’s ability to identify common concept linking three words
	DAS-II	Word Definitions (WD)	Vocabulary knowledge: measures ability of child to define orally presented words
	NEPSY-II	Word Generation Semantic (WGS)	Language acquisition, retrieval, and verbal productivity
Learning and Memory	NEPSY-II	Memory for Designs Delayed (MDD)	Long-term storage and retrieval of visual-spatial information
	NEPSY-II	Memory for Faces Delayed (MFD)	Retention of encoded facial features
	NEPSY-II	Memory for Names Delayed (MND)	Long-term recall of previously learned names
	NEPSY-II	Narrative Memory Free Recall (NMF)	Immediate story recall
Visual-spatial Ability	DAS-II	Recall of Designs (RD)	Short-term visual recall: measures child’s ability to recall and reproduce an abstract design
	DAS-II	Pattern Construction (PC)	Spatial ability: measures child’s ability to copy a design with wooden blocks
	NEPSY-II	Arrows (AW)	Visuoperception: measures child’s ability to judge line orientation

Note. DAS-II = Differential Abilities Scale, Second Edition

All DAS-II scores are T-Scores and all NEPSY-II scores are scaled scores.
