The experiments reported here investigate the effects of different kinds of set on hemisphere differences, and confirm that, in some conditions, the hemispheric asymmetry in a particular task may shift when cuing establishes an attentional set. (Author)

Human visual recognition on the basis of shape but regardless of size was investigated by reaction time methods. Results suggested two processes of size scaling: mental-image transformation and perceptual-scale transformation. Image transformation accounted for matching performance based on visual short-term memory, whereas scale transformation…

Attempts to determine if imagination could replace physical color and pattern in adaptation stimuli known to produce orientation-specific color aftereffects. (Editor/RK)

There is a conflict in the literature on selective attention. Five experiments were conducted to resolve this conflict, and all involved a comparison of tachistoscopic recognition when alternatives were either presented beforehand or not. (Editor/RK)

Attempts to settle the question of whether reading units are ever larger than letters and considers the variables expected to influence the size of the reading unit. (Author/RK)

Reports some additional research that may resolve questions about the meanings accessed in recognizing ambiguous words. (Author/RK)

Nonspeech stimuli were varied along two dimensions--intensity and rise time. In a series of speeded classification tasks, subjects were asked to identify the stimuli in terms of one of these dimensions. (Editor)

A new procedure for estimating the dichotic ear advantage is applied for the first time in conjunction with the single-response requirement. Most subjects showed unusually large right-ear advantages, making the present methodology interesting for the study of hemispheric asymmetry. (Editor)

Recent work by Hamill (1976) suggests that placement of monosyllabic content words in grammatical strings is correlated with the rhythmic pattern of the string. Using classic paradigms, this research shows that rhythmic organization is also evident in speech material without grammatical structure or the content word/function word distinction.…

As part of a search for a unified theory of attention, observers detected letters in streams of digits under conditions of divided or selective attention for a period of 10 hours. The practice effects on the detectability of targets and on the response criteria used by observers were evaluated. (Editor/RK)

Attempts to develop a method for investigating the process of phonemic encoding and explores the structural and linguistic variables that influence the length of time required for phonemic translation of sequences of graphemes. (Author/RK)

An experiment was designed to examine the contribution of phonetic information in the processing of words in tachistoscopic recognition masking. (Editor)

Although a feature detection theory of pattern recognition is consistent with many recent physiological findings, the specific rules governing the perception of the distinctive features of letters have not yet been determined. This article presents two new experimental procedures for determining these rules. (Editor)

Visual masking occurs when one stimulus interferes with the perception of another stimulus. Investigates which matters more for visual masking--that the target and masking stimuli are flashed on the same part of the retina, or, that the target and mask appear in the same place. (Author/RK)
