“Worse than I anticipated” or “This isn’t so bad”?: The impact of affective forecasting accuracy on self-reported task performance
Fig 2
Response surface area wherein self-reported performance is predicted by the anticipated—experienced positive affect discrepancy (Study 1).
Of note, when conducting polynomial regression, we scale-centered the predictors by subtracting the scale midpoint to reduce multicollinearity and aide interpretation. Each of the predictors evaluated in both studies were measured on a 5 point scale as noted in the Method sections; therefore we subtracted 3 from each predictor value, resulting in the values -2 to 2 in the along the X- and Y-axes in Figs 2–7. The variables on the Z- axes in Figs 2–7 are not centered and reflect the original 5-point Likert scale responses used (with the exception of time spent studying in study 2, which was assessed in minutes).
