Pearson correlation analysis in a cross-sectional study of 60 Korean adults aged 21 to 86, relating age to percentage accuracy on four passive-production conditions. The article reports coefficients of "-.50,-.55,-.46, and -.39" (all ps < .01), including r = -.55 for the priming-noncanonical condition.

"Age was significantly and negatively correlated with all four conditions of the sentence-production tasks with correlation coefficients of -.50,-.55,-.46, and -.39, (all ps < .01)"
