Reversal Shift

Drive level affected reversal rather than non-reversal-shift learning during initial shift-discrimination trials. Animals under high water deprivation during the original simultaneous discrimination and reversal-shift discrimination made more initial (first trial-block) errors during reversal-shift than animals that were maintained on moderate deprivation during either or both discrimination tasks.

Food Consumed

A total of 48 albino rats were observed over a 15-day period to determine the effects of drive level, maturation, and practice level on eating latency, amount of time during a 5-min. interval spent in eating, amount of food consumed, and rate of eating. In general, the effects of maturation and practice followed expected lines, with facilitation of consummatory behavior accompanying both maturational and experiential development. Although higher-drive Ss have shorter latencies and spend more time eating, they consume less food per unit of time spent in mastication than lower-drive Ss.

Better Than

Moderately (18 hr.) water-deprived rats were able to utilize an incidental cue of floor-texture following learning of brightness of a goal door better than highly water-deprived (23.5 hr.) animals only when water and sucrose liquids were paired with attributes of the new cue. These findings along with results from three subsidiary experiments indicate that drive level influences utilization of incidental cues by determining the differential incentive value of rewards predicted by attributes of those cues. This formulation is contrary to the drive level-focus of attention model of Tolman (1948) and Easter-brook (1959).

Large Deficit

8 albino rats received bilateral lesions of the hippocampus, 8 received bilateral lesions of the amygdaloid complex, and 8 served as unoperated controls. The rats were trained to find food at the end of an arm of a cross-maze, associated with a conspicuous light stimulus as the first task. Rats were required to relearn the first task with the light stimulus absent. Hippocampal-lesioned rats did not differ from controls on the first task but showed a large deficit on the second task.

Running Time

24 naive albino rats were run down a straight alley 30 trials a day. Half were fed 10 gm. per day and half 12. Half were run under spaced conditions and half under massed. All Ss stopped running although they were rewarded on every trial. Drive level was significantly related to days to extinction, and massing of trials was significantly related to running time. Implications of these findings were discussed.

And Control

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.
