Summary of Pearson’s correlations between MASQ Anhedonic Depression (AD) scores and probabilities of rich miss rates (i.e., selecting “lean” when a rich stimulus was actually presented) and lean miss rates (i.e., selecting “rich” when a lean stimulus was actually presented) as a function of the outcome in the preceding correctly executed response.

MASQ Anhedonic Depression
Rich Lean
Preceding trial Miss Rate Miss Rate
Rewarded Rich Pearson's correlation −0.110 a −0.190
p-value .617 .385
Rewarded Lean Pearson's correlation 0.005 0.290
p-value .980 .180
Non-Rewarded Rich Pearson's correlation 0.519 a,b −0.356

Non-Rewarded Lean Pearson's correlation −0.041,b −0.267

Rich miss rate = (1- rich hit rate), lean miss rate = (1- lean hit rate). MASQ: Mood and Anxiety Symptom Questionnaire (Watson et al., 1995).

a

Correlations are different at p = 0.039, t(20) = 2.21.

b

Correlations are different at p = 0.069, t(20) = 1.92.
