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)

Describes a series of experiments showing that in normal subjects (a) iconic storage occurs primarily in the retina in the photoreceptors and (b) under conditions of dark pre- and postexposure fields, the icon is mainly a rod phenomenon. Draws conclusions based on these experiments, discusses previous work done by others, and attempts to reconcile…

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)

To investigate human visual identification of different-sized objects as identically shaped, matching reaction times were measured for pairs of simultaneously presented random figures. (Editor)

Four experiments examined the effect of label training on redintegrative memory for novel shapes (remembering the whole shape when only a part is presented). (Editor)

Paper presented at the Annual Meeting of the Classical Association of Canada, Montreal, June 1972; article describes and evaluates the validity of prosopography (investigation of the common background of a specified group of historical actors via a collective study of their lives) as an approach to history.

Discusses two propositions about the preliminary stages of acoustic analysis and encoding in the absence of focal attention. (Editor/RK)

In four different experiments, brief illumination of a localized visual stimulus was followed by grain presentation unless the pigeon approached the light. Results indicate that although response-reinforcer relations do play a role, stimulus-reinforcer contingencies are the dominant factor in establishing and maintaining approaches to the…

A visual-spatial approach to the study of attention dysfunction was presented. The hypotheses of broadened and narrowed attention were tested by comparing peripheral visual discrimination of acute schizophrenic, chronic schizophrenic, and normal subjects within two regions of the functional visual field.
