Development of a method for increasing the utility of multiple correlations by considering both testing time and test validity
A modification of the Wherry-Doolittle test selection method is presented by which tests are included in a multiple correlation (obtained for a given battery of tests) in the sequence in which the rate of retu...

Field - articulation in recall
Performance on Witkin’s Embedded Figures and Rod and Frame Tests were related to recall and recognition of two lists of words in an interference situation. The results support Gollin and Baron’s (1954) finding...

Predecisional Search in Concept Formation: The Effects of Problem Complexity
Predecisional search was studied among 72 women Ss with concept formation problems in which total uncertainty, information per exemplar, and proportion of relevant attributes were controlled. Analyses of varia...

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 recovery of a visually masked target
Ss were briefly shown pairs of letters under backward masking and disinhibitive backward masking conditions. For the backward masking condition, a single homogeneous flash of light (M1), varying in duration, f...

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...
