Correlations between Factors of Depressive Symptomatology and Experimental Measures

Measure	Anhedonia	Negative Affect
Skin conductance: mean magnitude	−.28*	−.30*
Skin conductance: pleasant > neutral	−.30*	−.19
LPP: mean amplitude	−.27*	−.18
Postauricular reflex: pleasant > neutral	−.20	−.25*
Valence ratings: pleasant > aversive	−.18	−.25*
Arousal ratings: aversive > neutral	−.20	−.13

Note. n = 65 for skin conductance response, n = 79 for LPP amplitude, n = 83 for postauricular reflexes, n = 87 for emotion ratings.
