(A) Distribution of PVT reaction times for women (n = 16, left panel) and men (n = 16, right panel) during light exposure to 6500 K (black lines) and to 2500 K (dashed black lines lines). (B) Time-course of PVT median dim light (<8 lux), dark adaptation and reaction times during dim light and 2-h evening light exposure (white bar) at 6500 K (black lines) and at 2500 K (dashed black lines with open circles lines) for women (n = 16, left panel) and men (n = 16, right panel). (C) Same as for B, but for PVT performance was indexed as 10% fastest reaction times. Data illustrated as mean ± standard error of mean. *interaction of ‘light condition’, ‘session’ and ‘sex’, p < 0.05.
