Relationship between Food Habituation and Reinforcing Efficacy of Food
Carr, Katelyn A.; Epstein, Leonard H.
Learning and Motivation, v42 n2 p165-172 May 2011
Reinforcing value and habituation are two processes that have been used to study eating behaviors, but no research has examined their relationship, how they relate to energy intake, and whether they respond in a similar manner to food deprivation. Twenty-two female subjects were randomized to food deprived or non-deprived conditions, and assessed for food reinforcement, habituation to food and ad libitum eating. Results showed food reinforcement and habituation are correlated (r=0.62, p=0.002) and both independently predict energy intake. Hierarchical regression showed that the rate of habituation accounted for 30 percent of the variance in eating (p=0.008), and adding food reinforcement increased the amount of variance accounted for up to 57.5 percent (p less than 0.05). This suggests that both processes may influence energy intake in a meal.
