Measure Description |
Time Frame |
|---|---|---|
|
Measuring Reward association and valuation using the Reward Association Task
Time Frame: Change from Baseline at 8 Weeks
|
Based on signal detection theory, it evaluates response bias as a function of prior reward and permits an objective assessment of disorder-related sensitivity to reward.
To evaluate the how the 6 facets of reward are related to each other in unmedicated MDD patients in order to develop a clearer understanding of reward pathways
|
Change from Baseline at 8 Weeks
|
|
Measuring Expectation using a prediction error task, to measure learning and choosing, during functional Magnetic Resonance Imaging (fMRI)
Time Frame: Change from Baseline at 8 Weeks
|
This distinction was included in the design in order to dissociate potentially different neural circuits subserving learning reward associations and using them to guide behavior.
To evaluate the how the 6 facets of reward are related to each other in unmedicated MDD patients in order to develop a clearer understanding of reward pathways
|
Change from Baseline at 8 Weeks
|
|
Anticipation of reward using the monetary incentive delay during fMRI
Time Frame: Change from Baseline at 8 Weeks
|
This task was designed to disentangle anticipatory vs. consummatory phases of reward processing.
To evaluate the how the 6 facets of reward are related to each other in unmedicated MDD patients in order to develop a clearer understanding of reward pathways
|
Change from Baseline at 8 Weeks
|
|
Motivation/effort using the Cued-Reinforcement Reaction Time Task and the EEfRT task.
Time Frame: Change from Baseline at 8 Weeks
|
The Cued-Reinforcement Reaction Time Task (CRRT) provides an evaluation of reward-based reaction time speed as an index of incentive motivation.The EEfRT task allows analysis of the predictive value of reward probability and magnitude on effort-based decision making.
To evaluate the how the 6 facets of reward are related to each other in unmedicated MDD patients in order to develop a clearer understanding of reward pathways

|
Pleasure/Liking using the monetary incentive delay task in an fMRI
Time Frame: Change from Baseline at 8 Weeks
|
This task was designed to disentangle anticipatory vs. consummatory phases of reward processing.
To evaluate the how the 6 facets of reward are related to each other in unmedicated MDD patients in order to develop a clearer understanding of reward pathways.

Feedback integration using the Probabilistic Reversal Learning task during fMRI
Time Frame: Change from Baseline at 8 Weeks
|
participants are presented with a choice of two stimuli.
Based on their first choice, the selected stimulus will be rewarded with a high probability, while the other will be rewarded with a low probability.To evaluate the how the 6 facets of reward are related to each other in unmedicated MDD patients in order to develop a clearer understanding of reward pathways
