Comparison of Peterson and Harmon-Jones (2009) results to findings of the present study

Effect	Peterson & Harmon-Jones: LM	Present Study: AR/LM	Present Study: CSD
TOY	↓ midline and lateral LFA in fall in Study 1, laterally in study 2	significant ↑ LFA in fall compared to spring	sig ↓LFA in fall sessions compared to spring
TOD	Study 1:↓ midline LFA in mornings; Study 2: ns	ns	ns
TOY x TOD	Study 1: Sig laterally/mid- frontal; Study 2: Sig laterally	ns	ns
Photoperiod	Not examined	significant ↑ LFA in periods of less light compared to periods of more light (LM d = .07, AR d = .07)	ns (d = .015)
Photoperiod x TOD	Not examined	ns	ns
Photoperiod x TOD x TA	Not examined	LM =ns. AR=w/in morning sessions in less light ↓ LFA compared to those awake longer in periods of less light and the opposite pattern in periods of more light (Less light:, LM d =.15 AR d =−.25; More light: LM d = −.26, AR d =.35)	ns (Less light: d =−.10; More light: d=−.15)

Note: ns = nonsignificant effect; d= Cohen’s d.
