Temple, J. L., Kent, K. M., Giacomelli, A. M., Paluch, R. A., Roemmich, J. N., & Epstein, L. H. (2006). Habituation and recovery of salivation and motivated responding for food in children. Appetite, 46(3), 280-284.
36 children between 9 & 12 participated in 10 trials of 1 min each (1 min apart) in which they were shown half a cheesburger just in front of their mouth and instructed to smell it and think about eating it. Salivation was measured by weighing dental rolls before and after each trial. Amount of salivation declined with the repeated trials, but recovered on trial 8 in a group presented with french fries instead of cheeseburger.
