Change, stability, and instability in the Pavlovian guidance of behaviour from adolescence to young adulthood
Fig 6
Stability in descriptive estimates of Pavlovian bias, assessed by the interaction between the fractions of total correct answers in the four conditions, ((G2W-NG2W)+(NG2AL-G2AL))/2.
A. Stability assessed by baseline vs. long follow-up estimates. A positive correlation is detectable, rho~0.15, p = 5.4e-4. B. Difference in performance between the appetitive (two left) and aversive (two right) conditions. The horizontal lines show the median appetitive bias at baseline (G2W-NG2W; first violin plot; salmon) vs. long follow-up (second plot, in green). This significant difference (p = 0.0027) drives an overall reduction in the estimate of Pavlovian bias (p = 0.0019). The aversive context, NG2AL-G2AL, shows no significant change on its own (blue and mauve; p = 0.35). White boxes are interquartile ranges.
