Examination of the individual components of the PCA index revealed that, after reward devaluation, paired goal tracker rats, compared to unpaired goal tracker rats, showed a trend toward greater probability of lever deflection relative to receptacle entry during the CS (Figure 5C ; Z = 2.10, corrected p < 0.1); a significantly greater bias toward lever deflection over receptacle entry during the CS (Figure 5D ; Z = 2.63, p < 0.05); and a trend toward lower latency to interact with the lever, relative to the receptacle (Figure 5E ; Z = −1.67, uncorrected p < 0.1).
