Set size and crowding affect search efficiency by limiting attention for recognition and attention against competition; however, these factors can be difficult to quantify in complex search tasks. The current experiments use a quantitative measure of the amount and variability of visual information (i.e., clutter) in highly complex stimuli (i.e.,…

The present experiment was designed to investigate the influence of label training on the reporduction-recall of visual stimuli and follows in the tradition of the Gestalt memory-for-form literature. (Author)

The abstraction of prototypical information and the classification of new exemplars was investigated as a function of category size and the number of categories that had to be distinguished during learning. (Editor)

Recognition accuracy in a tachistoscopic identification task typically declines as the size of the set from which the target was selected increases. Article investigated whether set size had its effect through selective encoding from iconic store. (Editor/RK)

Aims at providing data for evaluating the proposition that associations between exteroceptive (outside) stimuli and illness play a role in determining the effect of unconditioned stimulus preexposure on subsequent taste aversion conditioning. (Author/RK)

Discusses four experiments concerned with environmental determiners of the taste familiarity effect. Specifically, external environmental stimulation experienced by the subject at the time of taste preexposure and taste conditioning was varied in order to assess its influence on taste aversion learning. (Author/RK)

Two sets of measurements evaluated performance on typographically inverted text that students had learned to read 13 to 15 months earlier. (Editor)

The purpose of the present work was to investigate the relation between pattern goodness and accuracy of reproduction in backward masking. It may be hypothesized that good patterns, being easier to encode as wholes, will be reproduced more easily than poorer patterns. Four experiments were performed. (Author)

In three experiments the location of pigeons was monitored during 20-second illuminations of a right or left key presented in various temporal relationships with food delivery. In general, subjects approached a signal positively correlated with food and withdrew from a signal negatively correlated with food. (Editor)

Subjects responded to pairs of test items from learned linear orderings (e.g., Tom is taller than Dick; Dick is taller than Sam, etc.). Results are compared with previous studies of ordered linguistic, perceptual, and numerical information. (Editor/RK)

This experiment was directed at clarifying the role of verbal associative responses in stimulus recognition. The effects of both distinctive and equivalent verbal labels were assessed. (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…

Three experiments are reported that were designed to delineate the properties of the stimulus encoding stage in reaction time tasks of varying stimulus-response compatibility. (Editor)

The concept of a scene schema was used to predict the kinds of information that will be remembered from complex pictures over relatively long periods of time. Recognition of eight types of transformations on both organized and unorganized pictures was tested either immediately following presentation or at intervals of a day, a week, or 4 months.…
