The albino rat: A defensible choice or a bad habit
Incest and natural selection
Replacement Behavior following Deprivation of Food, Water, Running, or Light
In 4 separate experiments albino rats were allowed to stabilize in rate on an activity (eating, drinking, light-exposure, or running), after which they were deprived of that activity for a time ranging from 2 to 8 days for different groups. The intent of the methodology was to apply the classical test for “drive”—increased comsummatory behavior following deprivation—to 4 different response measures and to examine in detail the time-course of defi…
Relationships among Three Measures of Home-Cage Activity
Some Properties of the Time-Course Stabilization of Running Behavior of Rats Living in Activity Wheel Units
It is important to have information about the duration of the adaptation period required for stable running rates in activity wheels both for planning the length of experiments and for scheduling treatments following the adaptation period. Much activity research circumvents problems of apparatus differences by using each animal as its own control, allowing treatment effects to be expressed as a percentage of the activity during the adaptation per…

Stimulus-Change versus Preference for Light
The classical procedure for demonstrating the reinforcing properties of stimulus-change for rats confounds the response-contingent change with the production of dim illumination. This experiment unconfounded the two by providing a response-contingent visual change without a change in the ambient illumination. This “pure” visual change was not reinforcing, whereas a response-contingent change from darkness to dim illumination—the classical procedu…
Extinction and Spontaneous Recovery of the Eyelid Cr as A Function of Delay of the Ucs and the Interval Between Acquisition and Extinction
Some effects of light upon the behavior of rodents
Self-Regulation of Luminance by Albino Rats
Self-Regulation of Luminance by Albino Rats
The reinforcing properties of the brief onset of dim light contingent upon bar-pressing are well established (Kish, 1955; Marx, Henderson, & Roberts, 1955). While current theory tends to attribute the reinforcement to the change in stimulation, it is possible that the absolute luminance produced by the change is important. If this were the case, rats allowed operant control of cage luminance should show a preference for a restricted range. If sti…
Identifying the Acceleration of Visual Targets
Subjects were required to distinguish between accelerated and constant‐velocity motion of targets. For different viewing times, ‘group thresholds’ were more nearly the same when relative acceleration was expressed in terms of total change of velocity during the viewing interval (v̇v/v̈) than when in terms of change per unit time (δv/v̈). This suggests that accelerated motion is identified by comparison of early and late velocities rather than by …
