Resistance to satiation as a function of three satiation procedures

Three groups of rats were trained to run a straight alley while hungry and tested while satiated. Group C was satiated only with lab chow, Group M with lab chow and wet mash, and Group P with lab chow and Noyes pellets. In satiated testing Group P ran significantly slower than Group C and ate fewer pellets in the alley than either group C or M. These results are consistent with an associative interpretation that assumes that resistance to satiation of eating and running is greater the higher the proportion of cues present in satiated testing that had been conditioned in acquisition.
