| 550240 | Left minus right hand response | Biased credit assignment in motivational learning biases arises through prefrontal influences on striatal learning | Go actions (irrespective of left vs. right) minus NoGo actions at the time people make a response. This is GLM2. The GLM contains the following 13 regressors: 1-8) 8 regressors crossing the performed action (Go/ NoGo) with the obtained outcome (reward/ no reward = neutral/ no punishment = neutral/ punishment). At the time of outcomes. 9) Left hand response. At the time of responses. 10) Right hand response. At the time of responses. 11) Incorrect response. At the time of responses. 12) Outcome Onset (any outcome). At the time of outcomes. 13) Invalid outcomes (non-instructed key pressed, returning error message). At the time of outcomes. This contrast is based on the left hand response (11) and the right hand response (12) regressors (at the time of responses), taking the difference between them (left minus right). Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020). |
| 550209 | Left minus right hand response | Striatal BOLD and midfrontal theta power express motivation for action | Contrast left hand Go responses (+1) with right hand Go responses (-1). NoGo responses count as 0. Contrasted at the time people see the cues and respond (deadline 1.3 seconds). Too late responses are registered as NoGo responses. Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020). Note that this Go/NoGo task is equiprobable (percent Go/NoGo trials is 50:50) and thus does NOT elicit strong inhibition-related activation. |
| 563793 | Midfrontal alpha oscillations | Biased credit assignment in motivational learning biases arises through prefrontal influences on striatal learning | Parametric regressor: trial-by-trial frontal (t-weighted mean of channels Cz/ FCz/ Fz) lower alpha band oscillations (0–425 ms relative to outcome onset, 6 - 10 Hz) measured using scalp EEG. This alpha band response is significantly higher when previously, a Go response was performed than when a NoGo response was performed. This regressor is added on top of GLM2 regressors (featuring 8 outcome x response regressors plus standard prediction errors and the difference term to biased prediction errors), yielding GLM3A. Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020). |
