Note. Field 4 (Berket el Sabe) was used as the reference category. Field 1 = Quesna; Field 2 = Alshohadaa; Field 3 = Tala. Significant estimates are bolded, all ps <.05. Cognitive = cognitive latent variable; BVRT = Benton visual retention task; DST = digit span task forward (F) and reverse (R); MTS = match to sample; SDL = serial digit learning; SDT = symbol digit task; VMI = visual motor integration; motor = motor latent variable; SAP = santa ana pegboard right (R) and left (L); SRT = simple reaction time; TAP = tapping alternating (A), left (L), and right (R).
