3.2.5. Perceived fat intensity ratings and the reinforcing value of food
When ratings of perceived fat intensity were examined, the significant predictors of breakpoint were expectorated fat at the two highest concentrations, 33% and 38% (β=−0.698 and β=−0.631; p= .018 and p= 0.003). Lower perceived intensity ratings of fat (indicating impaired sensitivity) were associated with higher breakpoints for the reinforcing value of food (Fig. 2B). Perceived intensity ratings of swallowed fat tastants at the same concentrations were not significant predictors of the reinforcing value of food nor were any of the other predictor variables (all p> 0.10).
