A priori cognitive constructs

A priori cognitive construct	Associated cognitive test(s)
Episodic memory	WMS-IV Logical memory (immediate and delayed)
	WMS-IV Verbal pairing (immediate and delayed)
Processing speed	Trail Making task A
Verbal fluency	CFLˆ
Working memory	Trail Making test A minus Trail Making test B
	OSPAN
Reasoning	Raven’s progressive matrices
	KBIT-2 non-verbal scoresˆ
Verbal ability	Shipley vocabulary subtest
	KBIT-2 verbal scoresˆ

Note. We composed a priori constructs based on the methods and construct categories of Chan et al. (2014). Scores for the tests associated with each construct were converted to z-scores and averaged with other tests associated with the same construct. Tests whose scores are normally adjusted for age are indicated withˆ. Since we are interested in age effects, we performed the z-score conversions on the raw scores instead of the age-adjusted scores. WMS = Wechsler Memory Scale; CFL = verbal fluency test (letters CFL); KBIT = Kaufman Brief Intelligence Test.
