Note. Table reports hierarchical generalized linear model (HGLM) population average results with robust standard errors for Level-1 intercepts. b = regression coefficient, OR = odds ratio, CI = confidence interval, Prob = estimated probability of success. The HGLM includes both formal schooling and Swahili language skill and as Level-2 predictors. Self-reported formal schooling was entered based on the number of years completed. Self-reported Swahili language skill was dichotomized as 0=poor, 1=good. The intercept for each condition, what we call “minimal cultural exposure”, tests performance against chance-level responding for participants who self-reported poor Swahili language skill and had no years of formal schooling. For models separately examining Schooling and Swahili as Level-2 predictors, see Supplementary Information Table 10.
