“…These results suggest that food deprivation does not produce the same kind of heart rate activation effect under appropriate Belanger and Feldman (1962) with water deprived animals. My results stand in contradiction to those of Jolley (1970) who has reported heart rate activation in food deprived animals. Winer (1970) has also reported a failure to obtain heart rate activation using salt-arousal of thirst.…”

Heart rate, an activity index, and duration of grooming and rearing episodes were measured in rats which lever-pressed under either continuous or variable interval schedules of reinforcement while undergoing increasing levels of food deprivation. The results showed heart rate level did not change with increasing deprivation in lever pressing animals and did not seem to be influenced by activity levels or behaviour patterns such as rearing or grooming. Extinction produced a decrease in heart rate level, though behaviour became more invigorated. Observations of phasic heart rate and activity curves associated with instrumental lever responses are also presented. The data are discussed in relation to studies showing heart rate-deprivation functions and heart rate-movement associations. VANDERWOLF AND VANDERWART (1970) observed that heart rate recorded in rats under conditions of satiation and food deprivation was associatedwith phasic movements or erectness of posture. It was found that heart rate was higher during face washing, licking, and rearing, than during scratching, walking, and resting. Food deprivation up to 47 hours had no effect on heart rate measured during these various specific categories of behaviour. Vanderwolf and Vanderwart (1970) suggest that many of the studies relating heart rate in the rat to learning, motivation, arousal, etc. may be demonstrating only the effects of changes in these specific motor patterns on heart rate. The present experiment attempts to examine this possibility with regard to the heart rate level and hours of deprivation relation described by Belanger and Feldman (1962) and others. Reviews of experiments concerned with heart rate and deprivation can be found in Appley (1970), Belanger (1967), Rlevings (1971), Campbell and Misanin (1969), and Malmo and Belanger (1967.The present study examines activity levels and behaviour patterns (grooming and rearing) for the influences on heart rate suggested by Vanderwolf and Vanderwart (1970). In addition, an attempt is made to assess the role of activity in reinforcement-related phasic heart rate patterns of the type obtained by Ehrlich and Malmo (1967).

“…decrease in heart rate of rats as the length of feed deprivation increased to 72 hours. Jolley (1970) did not find a significant reduction in heart rate of rats deprived of feed up to 72 hr, but found a significant increase in heart rate after refeeding. Decreased blood volume and increased PCV, serum Na and serum K in rats were found with feed and deprivation (Sullivan et al, 1969;Faridy, 1970); the increases in blood parameters were more pronounced during water deprivation.…”

Two trials were conducted with a total of 12 beef heifers and steers to determine the effect of 48-hr deprivation of feed or water or both on rectal temperature, respiratory and heart rates, electrocardiograph (EKG) patterns, packed cell volume (PCV) and the concentrations of serum sodium, potassium, calcium and magnesium. The same measurements plus the serum concentration of total acid-soluble phosphorus were made in a third trial with six steers and a 96-hr deprivation period. A fourth trial was conducted with three rumen fistulated steers to determine the effect of manually emptying the rumen on EKG patterns, Deprivation of feed or water or both for 96 hr reduced (P<.05) rectal temperature by 1.5% and respiratory rate by 47% and increased (P<.05) P and R EKG amplitudes by 33% and 35%, respectively, PCB by 21% and serum phosphorus by 43%. Deprivation reduced heart rate 19% and increased serum sodium and potassium 12 and 23%, respectively, but these changes were not significant. These changes appeared smaller and less consistent for animals deprived for 48 hours. The physiological changes associated with both 48-hr and 96-hr deprivation were most pronounced during the deprivation period and for 24 hr after reintroduction of feed and water with little evidence of treatment effects 48 hr after the reintroduction of feed and water. For animals deprived 96 hr, changes in respiratory rate (P<.01), PCV (P~.05) and serum phosphorus (P<.05) were greater for the animals fed concentrate than for those fed in obtaining the physiological measurements in these trials.forage; changes in heart rate and the P-R and T-P EKG intervals tended to be greater for the animals deprived of both feed and water than for animals deprived of feed or water alone. Manually emptying the rumen had little effect on EKG patterns. In the absence of engorgement after a deprivation period as long as 96 hr, the measurements in this study indicated that beef cattle return quickly to a physiologically normal state. (

“…This general position has been supported by a number of studies on animals under food or water deprivation, employing HR as a measure of activation. Several kinds of relevant stimulation have been used: consummatory behavior itself (Eisman, 1966;Jolley, 1970a); the operant situation (Belanger & Feldman, 1962); and prior association of the test environment with primary reinforcement (Goldstein, Stern, & Rothenberg, 1966). Jolley (1968) has also shown that nonrelevant stimuli (changes in illumination level not previously associated with feeding) are not effective in promoting HR increases after food deprivation.…”

Ss were deprived of food for 24 h, after which heart rate (HR) was recorded with food placed before the Ss and also after they had eaten it. It was predicted, according to Malmo's interaction hypothesis, that HR in both situations would be higher than at a controllevel but that the increase after food ingestion would be greater than that found in the presence of visual cues. The results did not wholly support these predictions. Only after eating were significant HR increases found. Possible reasons for the discrepancies between findings in this area were discussed.
