a) Pavlovian Conditioned Approach (PCA) score across training days.
Black line=control, grey line=ACRS. Positive values indicate
bias toward the CS+ lever (sign tracking), negative values indicated
bias toward food cup (goal tracking) *p<0.05, group ×
day interaction. b) Mean+SEM PCA Score on training days
7&8 show with black (control) or grey (ACRS) horizontal lines and error
bars. Individual rats’ data are represented with white or grey circles.
c) Rat-by-rat PCA scores, ranked from most negative to most
positive. Control rats=black bars, ACRS rats=grey bars, ACRS
rats defined as intermediates (PCA<0.3 and
>−0.3)=white bars). d) CS+ lever
(solid black, grey lines) and during cue food cup entries (dashed black, grey
lines) emitted during the first, second, or third 25-cue blocks on sign/goal
tracking extinction training test. * p<0.05, Main effect of ACRS
on food cup entries.
