The objectives of this study were (a) to examine the dimensionality of the Thorndike Dimensions of Temperament (TDOT) when administered in a single stimulus form; and (b) to test a set of hypotheses relative to the constructs measured in the TDOT. (Author/RK)

Even though many investigators have observed increased intakes of edibles as a function of prior exposure, little systematic research has been done on the effect. The present study was designed to investigate the phenomenon in domesticated rats with a concentrated solution of sodium saccharin used as the ingested substance. (Author)

Computer models of asymptotic reversal learning in pigeons were evaluated on the basis of the results of five experiments which defined the asymptotic pattern of within-sessions and between-sessions reversal (Experiment 1) and which provided data on the effects of intertrial interval (Experiment 2), amount of training preceding reversal…

The major concern of the present experiment was to determine whether increased covert rehearsal is the sole cause of the release from proactive interference in short-term memory. (Editor)

Approximately 200 college institutions were surveyed in an effort to find out about the quality of introductory college-level psychology courses. Results are discussed on kinds of instructors, class size, problems of numbers, format, methods of evaluation, content, and implications of innovations. (JR)

These experiments attempted to discriminate among theories of the spaced-practice effect and to further explore the phenomenon of proactive interference. (Author/RK)

Four retroactive inhibition (RI) experiments involving the AB, AC (same stimuli, different responses) paradigm were conducted to determine whether learning the original list (OL) and the interpolated list (IL) under different color-context conditions (different) would reduce RI relative to learning both lists under the same context conditions…

The purpose of the present experiment was to compare the effects on performance and mood of reduced and extended sleep with those following temporal shifts of sleep in a single group of subjects who characteristically sleep 9.5-10.5 hours per night. (Author)

Some task variables that influence sentence coding, and the ways in which those influences appear to be manifested in performance were outlined. Trends in empirical data were examined as evidence for two classes of coding strategies. (Author/RK)

The main objective of the present investigations was to determine whether or not young human infants see the physical spectrum in a categorical fashion as human adults and animals who possess color vision regularly do. (Author)

To test a theory that selective attention to threatening stimuli induces paranoia, an attempt was made to manipulate attention to threatening and nonthreatening statements among college students and examine the effects on three indices of paranoia. (Editor)

It was hypothesized that individual differences in eating behavior based on the distinction between obese and normal subjects could be demonstrated within a population of normal subjects classified as to the extent of restraint chronically exercised with respect to eating. (Editor)

The relation between intelligence at admission and subsequent rehospitalization was examined in 91 schizophrenic males. (Editor)

Three experiments addressed the problem of isolating the effects of sensory similarity on subprocesses involved in coding paired associates. (Editor)
