Both the low cortisol
subject group and the high cortisol
subject group were compared to assess the correct key response and reaction time in cognitive performance. (A, B) Mean (± s.e.m.) correct response and reaction time in two groups. There is no significant difference between the low cortisol10 pm group and the high cortisol10 pm group in performance in either the attention or the language task. (C) Low cortisol10 pm subjects show a significantly more accurate correct key response than that of high cortisol10 pm subjects in the novel object discrimination task. *Significant group difference at p < 0.005.
