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)

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)

Five reaction time experiments explored word frequency effects in word-nonword decision tasks and in pronunciation and memory tasks. Analysis of the response latencies using Sternberg's additive-factors approach indicates that frequency effects consist of both effects in encoding and in retrieval from memory. (Editor/RK)

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)

Subjects were required to discriminate previously learned "standard" versions of angular shapes from randomly perturbed "distrator" versions that varied in similarity to the standard. (Editor)

The rate of speaking in words per minute is a function of three independent variables, namely, articulation rate and the number and durations of pauses. The present study varies each of these components separately in a factorial design in order to determine how the listener combines them into a global impression of speech rate. (Editor)

Examines an alternation effect and a repetition effect in a two-choice reaction time task. Two further experiments examine the roles of subjective expectancy and an automatic facilitation in determining these effects. (Editor/RK)

Measures the phenomenal and the functional durations of visual stimuli differing in informational value. (Author/RK)

Demonstrates that categorization of speech sounds can be influenced by the phonetic structure of connected speech. (Editor/RK)

This article is concerned with the perceptual load in searching for a number of kinds of target which are presented for a fixed, short period of time. The aim is to establish data which any acceptable model of human information processing will need to fit. (Author)

Two initial experiments demonstrated that direction aftereffects of potentiation in the extraocular muscles (induced through sustained versional rotation to the side) generally increase as a function of the magnitude and duration of the inducing ocular rotation and can be built up under conditions of varied as well as constant fixation. (Editor)

By presenting moving bars of different widths to the two eyes, an attempt was made to model the differential visual persistence produced by differential intensity filtering in the two eyes (the Fertsch-Pulfrich effect). (Editor)

In four experiments involving blindfolded subjects, constant errors in the haptic judgment of extent in the horizontal plane were found to relate consistently to the time and velocity of limb movement. Taken together with additional information on judgments of movement duration, the results suggest that the illusion of extent is modulated by the…

On each of 10 trials, 80 college students were presented with a different set of five anagram tasks varying in complexity. Half the subjects rated the tasks for the amount of interestingness and half for the amount of pleasantness. (Editor/RK)

To determine whether perceptual asymmetries for faces occur at early or late stages of stimulus analysis, subjects compared the members of a pair of faces which appeared in the right or left visual field, either to each other or to a previously presented sample. (Editor)
