aCorrelations for males and females provided where group differences are significant or showing a trend towards significance for gender differences. Digit Symbol: male r = .217, p = .033, female r = .253, p = .132; key search: male r = .112, p = .273, female r = .175, p = .301; mean EF: male r = .101, p = .324, female r = .222, p = .187; AQ: male r = .264, p = .009; female r = .121, p = .477. NB correlations are not significantly different to each other on Fisher’s r: Digit Symbol scaled score (z = − .19, p = .849); Key Search Profile Score (z = − .32, p = .749); Mean EF percentile (z = − .62, p = .535); AQ (z = .74, p = .459)
