Note: ⁎⁎Correlation is significant at the .01 level; ⁎Correlation is significant at the .05 level; Beta coefficients presented were based on the standardized scores. WL: word length; OrthN: orthographic neighbourhood size; SES: summed error score; Group: severity group; SES_Group: the product of summed error score and group; WL_Group: the product of word length and group; Ln_CE_Freq: log CELEX frequency; SES Residual: residual of regressing SES by WL; WL Residual: residual of regressing WL by SES.
