Antisaccade Costs with Static and Dynamic Targets
In the present study we examined the antisaccade cost (latency difference between antisaccades and prosaccades) in a variety of search tasks. In a series of experiments participants searched for a target and were required to execute a saccade toward...
Crossmodal Binding: Evaluating the "Unity Assumption" Using Audiovisual Speech Stimuli
We investigated whether the "unity assumption," according to which an observer assumes that two different sensory signals refer to the same underlying multisensory event, influences the multisensory integration of audiovisual speech stimuli. Syllables...
Formation of Visual "Objects" in the Early Computation of Spatial Relations
Perceptual grouping is the process by which elements in the visual image are aggregated into larger and more complex structures, i.e., "objects." This paper reports a study of the spatial factors and time-course of the development of objects over the...
Hemispatial Asymmetries in Judgment of Stimulus Size
Recent research has demonstrated a leftward bias in judgments of size. In the present experiments, hemispatial size bias was measured through simultaneous presentation of a circle and an ellipse varying in horizontal or vertical extent. A consistent...
Information Persistence in the Integration of Partial Cues for Object Recognition
A great many studies have shown that the perceptual effects of very brief visual stimuli can persist beyond the duration of the stimulus itself. These effects include sustained perception of the stimulus even though it is no longer present and the integration...
On Observing Another Person's Actions: Influences of Observed Inhibition and Errors
It was investigated whether an observer would simulate another person's inhibitory and error processes. Two participants sitting next to each other performed a stop signal task in which they occasionally had to try and inhibit their response when indicated...
Picking Up the Pace: Effects of Global Temporal Context on Sensitivity to the Tempo of Auditory Sequences
This article continues a line of research examining factors affecting listeners' auditory tempo sensitivities. Of particular interest is the question of whether listeners are sensitive to the overall (global) pace of their auditory environment and how...
Sensorimotor Synchronization with Chords Containing Tone-Onset Asynchronies
Musical ensemble performance requires the synchronization of multiple performers, resulting in sequences of chords containing multiple tones with multiple onsets. Experiments 1 and 2 investigate whether sensorimotor synchronization with chord sequences...
Stopping Eye and Hand Movements: Are the Processes Independent?
To explore how eye and hand movements are controlled in a stop task, we introduced effector uncertainty by instructing subjects to initiate and occasionally inhibit eye, hand, or eye + hand movements in response to a color-coded foveal or tone-coded...
Subjectively Divided Tone Components in the Gap Transfer Illusion
When a long glide with a short temporal gap in its middle crosses with a continuous short glide at the temporal midpoint of both glides, the gap is perceived in the short glide instead of in the long glide. In the present article, we tested possible...
Task-Dependent Costs in Processing Two Simultaneous Auditory Stimuli
A listener presented with two speech signals must at times sacrifice the processing of one signal in order to understand the other. This study was designed to distinguish costs related to interference from a second signal (selective attention) from costs...
The Linear Perspective Information in Ground Surface Representation and Distance Judgment
Most ground surfaces contain various types of texture gradient information that serve as depth cues for space perception. We investigated how linear perspective, a type of texture gradient information on the ground, affects judged absolute distance and...
The Relationship between Covert and Overt Attention in Endogenous Cuing
In a standard Posner paradigm, participants were endogenously cued to attend to a peripheral location in visual space without making eye movements. They responded faster to target letters presented at cued than at uncued locations. On some trials, instead...
The Time Course of Perceptual Grouping: The Role of Segregation and Shape Formation
The time course of perceptual grouping was examined in two experiments, using a primed matching task. In different conditions, elements were grouped into columns/rows by common lightness, into a shape (triangle/arrow or square/cross) by common lightness,...
Visual Dominance and Attention: The Colavita Effect Revisited
Under many conditions, humans display a robust tendency to rely more on visual information than on other forms of sensory information. Colavita (1974) illustrated this visual dominance effect by showing that naive observers typically fail to respond...
