Abstract
"For 100 days pre- and postfeeding weight measures were recorded for a group of rats allowed access to a wet mash preparation for 1 hr. each day" and for a control group which had food and water always available. "The prefeeding weight curve declined until Day 8 and then rose continuously. At the end of the 100-day period the mean prefeeding weight was 30 gm. higher than the starting weight . . ‥ The consummatory response increased until Day 25" and then remained stable. There was little relationship between these measures. "A plot of the mean weight lost during the preceding deprivation interval followed almost exactly that of the consummatory response." These measures were highly correlated and it is suggested that weight lost is a better measure of the relationship between deprivation and food consumption. From Psyc Abstracts 36:01:1EF23E.
