Hebb, 1955;Malmo, 1959) have suggested that the relationship between performance and arousal or "activation" is a curvilinear one. These authors propose that an optimal level of arousal exists for any given task and deviations from this level in either direction will result in a decrement in performance.A study by Belanger (1959), using heart rate as the measure of activation, has yielded results favorable to this inverted U hypothesis. In this study, heart rate and performance in a Skinner box were measured at five levels of water deprivation. Results showed that, while heart rate increased steadily from 24 through 72 hr. of deprivation, performance increased, then reached a peak at 48 hr., and decreased thereafter.A number of objections to Malmo's interpretation (1959) of Belanger's results can be raised, (a) If, during training, heart rate became adapted to the 24-hr, deprivation

“…The paucity of information is especially surprising when one considers the number of investigations involving the recording of cardiac activity in rats (e.g. ]\IcCleary, 1954; Stern & Word, 1961). Similarly, despite the known existence of sweat glands on the volar surface of the rat's paws (Ring & Randall, 1947), few studies have dealt with GSR in the rat (see Wagner, 1950).…”

A comparison was made between classical conditioning and pseudoconditioning of heart rate (HR) and galvanic skin response (GSR) using low or high intensity shock as unconditioned stimuli (UCS). Conditioning treatment involved 5‐sec delayed conditioning, 32 trials/session for 5 sessions with shock administered randomly on half the trials. Pseudoconditioning was exactly the same except for pairing of CS and UCS. In contrast to pseudoconditioning, which produced mild acceleration of HR, minimal GSR, and frequent somatic response to the CS (as defined electromyographically), conditioning treatment produced consistent deceleration of HR, larger magnitude and frequency of GSR, and minimal overt somatic response to CS. The conditioned decelerative HR response developed rapidly and persisted throughout the experiment. Such apparent conditioning phenomena may still involve sensitization‐type effects and somatic interactions.

“…Light onset, by comparison, evoked only slight effect in heart-rate reactivity. Previous work (Black, 1964;Stern & Word, 1961) reported decreases in heart rate to the initial presentation of acoustic stimuli in rats whereas light stimuli have been found to be less effective in rats (Bloch-Rojas, Toro, & Pinto-Hamuy, 1964) and dogs (Petelina, 1958) in influencing heart-rate responses. However, it is possible, as Graham and Clifton (1966) suggest, that the critical difference may not be auditory vs. nonauditory stimulation, but whether stimulus rise times in this case were faster with auditory than nonauditory stimuli.…”

Heart rate, defecation, and behavioral responses to novel stimuli were investigated in the MR and MNR strains of rats. The MR rats exhibited higher heart rate after handling and larger increases in heart rate during stimulation. Females responded with higher heart rate than males during handling and larger increases in heart rate during stimulation. The MR rats defecated more than the MNR rats during test sessions. The correlation of heart-rate levels and response measures with defecation scores indicated a significant positive relationship. Both autonomic and behavioral measures exhibited considerable specificity of response when light and acoustic stimuli were compared, the latter evoking larger autonomic responses and having least dynamic effect on rearing and activity. The data indicate an important genetic effect on heartrate reactivity in the rat.
