Structural equation model of performance in Experiment 2. Measures: RS = running span, VA = visual arrays, AS = auditory sequences, CS = counting span, LS = listening span, RA = Ravens Progressive Matrices, PA = Stanford-Binet pattern analysis, VO = Stanford-Binet vocabulary, PV = Peabody Picture Vocabulary Test, NVIQ = nonverbal IQ, VIQ = verbal IQ.
