Reinforcing properties of odors for the albino rat

Food deprived and satiated rats were tested in a free operant situation to evaluate the behavior directing properties of odors that were either familiar and significant (food) or novel (amyl acetate). Both odo...

An evaluation of carbon dioxide as a short acting anesthetic

The use of carbon dioxide (CO₂) as a quick-acting anesthetic of short duration was studied. Sixteen rats were exposed to a CO₂ atmosphere for 10 and15 sec on separate days. Records were taken of the time required...

Odor cues in a maze discrimination

Rats were found capable of making the choice in a T-maze using the odor from only one 45-mg Noyes food pellet as a discriminative stimulus. This finding points to the need for controlling odor stimuli in the t...

The effect of reversible lesions in the posterior hypothalamus on conditioned suppression

Three rats with cannulae implanted in the posterior hypothalamic area and one nonimplant rat were tested in a conditioned suppression paradigm. During the acquisition phase of conditioned suppression, xylocain...

Schedule control in the rabbit

Operant responding for water reinforcement was investigated in three New Zealand albino rabbits. Performance of two rabbits under FR3, FR8t and FR95 schedules was similar to the performance of other organisms ...

The effect of the onset of stimuli on reactivity in the rat

Forty rats, maintained on either ad lib food and water or on 22-h food deprivation, were tested in a photobeam cage under conditions of no specific external stimulation or where tone, light, or the odor of amy...

Interval estimation as a function of constant and interrupted stimulation

The present study investigated the relationship between a temporal interval’s perceived length and the amount of stimulus and stimulus change within that interval. In three separate tests, completely filled in...

Odor stimuli, training procedures, and performance in a T-maze

This study demonstrates that rats can use odor cues to learn a T-maze discrimination task, thus supporting the findings of a previous study. Furthermore, only a very small quantity of dried food (45 mg) was ne...

The effect of visual masking on the critical duration of form

The Ss were briefly shown pairs of letters under various conditions of simultaneous masking. For the simultaneous masking conditions, a single homogeneous flash of light (MS), 1 msec in duration, followed the ...

The role of the standard in an auditory amplitude discrimination experiment

The role of the standard in a fixed-standard experiment of auditory amplitude discrimination was examined by varying the proportion of trials on which it was presented. The results suggest that the Os may use ...

Relative effects of acoustic and semantic relatedness on clustering in free recall

An 18-word list was constructed so that each word belonged to both a semantically related category and an acoustically related category. The list was presented, either orally or visually, in a multitrial free-...

Absence of binocular interaction between spatial and color attributes of visual stimuli

The hypothesis that induction of the McCollough effect (spatially selective color aftereffects) entails adaptation of monocularly driven detectors tuned to both spatial and color attributes of the visual stimu...

Stereospatial masking and aftereffect with normal and transformed random-dot patterns

Masking and aftereffect in the perception of binocular depth were studied using random-dot sterograms as adaptation and target stimuli. Detection of the target was impaired by prior adaptation only when the tw...

Stimulus compounding in pigeons

Two pigeons were trained on a three-ply multiple schedule in which reinforcement was available on a VI 1-min schedule for two of the components and extinction was in effect for the third component. SDs associa...

Habenular lesions and avoidance learning deficits in albino rats

Albino rats were given either habenular lesions or control operations and evaluated postsurgically during one-way active avoidance and passive avoidance training. Rats with habenular lesions, particularly thos...

Response programming vs. alternative interpretations of the “dit-dah” reaction time effect

In a three-choice reaction time paradigm, subjects made buttonpress responses of short, medium, or long duration. Reaction time increased monotonically with the three levels of required response duration for e...
