This study examines how audiovisual signals are combined in time for a temporal analogue of the ventriloquist effect in a purely temporal context, that is, no spatial grounding of signals or other spatial facilitation. Observers were presented with two successive intervals, each defined by a 1250-ms tone, and indicated in which interval a brief…

A four-part experiment was carried out to study the relationship between the time course of object-feature perception and the time course of retrieval of object information from memory. The experiment consisted of 2 perceptual matching tasks, and 2 perceptual recognition tasks. In all 4 tasks, participants provided speeded judgments of the…

This paper describes and tests a two-stage model for a "semantic congruity effect" in comparative judgments. (Editor)

The purpose of this study was to establish a theoretical framework for Stevens' empirically derived power law. Three models were proposed to explain the power law. (Editor)

Forty subjects were trained to make numerical predictions of a criterion from a cue. (Editor)

Two experiments were designed to test a number of finite-state self-terminating memory-scanning models for choice reaction times. (Editor)

When shown a pair of digits and asked to select the larger of the two, subjects make their choice more quickly as the numerical difference between the digits increases. Presents and tests a semantic coding model that can explain this and all previous results. (Editor)

Three experiments examined what happens to reaction time to verify easy items when they are mixed with difficult items in a verification task. Subjects verification of simple arithmetic equations and sentences took longer when placed in a difficult list. Difficult sentences also slowed the verification of easy arithmetic equations.
