Interaction Between Task and Antipsychotic Medication Dose (CPZ) on Reaction Time During (3) Congruent Trials or (4) Incongruent Trials
| Factor | β | SE | t | P |
|---|---|---|---|---|
| Congruent trials | ||||
| Intercept | 0.21 | 0.13 | 1.65 | .110 |
| Task | −0.20 | 0.05 | −4.17 | <.001 |
| CPZ | 0.17 | 0.14 | 1.18 | .245 |
| Task × CPZ | −0.13 | 0.05 | −2.47 | .015 |
| Incongruent trials | ||||
| Intercept | 0.34 | 0.13 | 2.68 | .012 |
| Task | −0.04 | 0.06 | −0.76 | .454 |
| CPZ | 0.05 | 0.15 | 0.38 | .708 |
| Task × CPZ | 0.09 | 0.07 | 1.27 | .215 |
Note: CPZ, chlorpromazine; RT = reaction time. The 2 models were defined as: RT = β0i + β1iTask + β2CPZ + β3TaskCPZ + ε.
