Description of the free parameters in the social controllability model and current findings related to computational psychiatry.
| Free parameter | Name | Description | Range | Impacted in delusion | Impacted in Miso-OC |
|---|---|---|---|---|---|
| f0 | Initial norm | An individual’s initial expectation of offers prior to beginning the task | $0 ≤ f0 ≤ $20 | ||
| ϵ | Norm adaptation rate | Degree to which an individual updates their norm expectations | 0 ≤ ε ≤ 1 | ||
| α | Aversion to norm violations | Degree to which an individual is averse to norm violations | 0 ≤ α ≤ 1 | Higher α in uncontrollable condition | |
| δ | Expected influence | Amount of the offer changes that an individual estimated would be induced by rejecting the current offer | −$2 ≤ δ ≤ $2 | Higher δ in uncontrollable condition | Greater difference between perceived controllability (self-reported) and δ in uncontrollable condition |
| β | Inverse temperature | Degree to which an individual weighs the current utility of a choice | 0 ≤ β ≤ 20 |
