Abrupt Onsets Capture Attention Independent of Top-Down Control Settings
Previous research using a spatial cuing paradigm in which a distractor cue preceded the target has shown that new objects presented with abrupt onsets only capture attention when observers are set to look for them (e.g., Folk, Remington, & Johnston,...
A Further Test of Sequential-Sampling Models That Account for Payoff Effects on Response Bias in Perceptual Decision Tasks
Recently, Diederich and Busemeyer (2006) evaluated three hypotheses formulated as particular versions of a sequential-sampling model to account for the effects of payoffs in a perceptual decision task with time constraints. The bound-change hypothesis...
Color Constancy: Phenomenal or Projective?
Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4,000 K and then...
Compensatory Properties of Visual Information in the Control of Isometric Force
This experiment investigated the effects of spatial (gain) and temporal (frequency) properties of visual feedback on the control of isometric force output. Participants performed an index finger isometric force production task with five different levels...
Does Attention Move or Spread during Mental Curve Tracing?
There are two theories that attempt to explain how attention is deployed when lines are traced. Initially, it was believed that a covert zoom lens moved along the line. Recent evidence has, however, suggested that attention spreads along the line, rather...
Gender Differences in Spatial Perception of Body Tilt
The tendency for observers to overestimate slant is not simply a visual illusion but can also occur with another sense, such as proprioception, as in the case of overestimation of self-body tilt. In the present study, distortion in the perception of...
Inhibition of Return for the Discrimination of Faces
When a target appears unpredictably in the same rather than a different location relative to a preceding onset cue, reaction times (RTs) of participants tasked with responding to the target are slowed. This pattern of results, referred to as inhibition...
Inhibition of Return in Single and Dual Tasks: Examining Saccadic, Keypress, and Pointing Responses
Two experiments are reported in which inhibition of return (IOR) was examined with single-response tasks (either manual responses alone or saccadic responses alone) and dual-response tasks (simultaneous manual and saccadic responses). The first experiment-using...
On Estimating the Difference Limen in Duration Discrimination Tasks: A Comparison of the 2AFC and the Reminder Task
This article assesses whether the two-alternative forced-choice (2AFC) and the reminder tasks (i.e., method of constant stimuli) yield identical estimates of the difference limen (DL). In a series of six experiments, participants discriminated between...
Perception of Alternated Speech Operates Similarly in Young and Older Adults with Age-Normal Hearing
When speech is rapidly alternated between the two ears, intelligibility declines as the rate of alternation approaches 3 to 5 switching cycles per second, and then, paradoxically, returns to a good level beyond that point. We tested intelligibility when...
Precuing Benefits for Color and Location in a Visual Search Task
Selection in multiple-item displays has been shown to benefit immensely from advance knowledge of target location (e.g., Henderson, 1991), leading to the suggestion that location is completely dominant in visual selective attention (e.g., Tsal &...
Remembered Instructions with Symbolic and Perceptual Comparisons
Semantic congruity effects (SCEs) were obtained in each of two experiments, one with symbolic comparisons and the other with comparisons of visual extents. SCEs were reliably larger when the instructions indicating the direction of the comparison were...
Spatiotemporal Context Influences Perception of an Ambiguous Target in Visual Search
The two-stage model of amodal completion or TSM (Sekuler & Palmer, 1992), and the ambiguity theory (Rauschenberger, Peterson, Mosca, & Bruno, 2004) provide conflicting accounts of the phenomenon of amodal completion in 2-D images. TSM claims...
The Encoding Process of Nonconfigural Information in Contextual Cuing
Jiang and Wagner (2004) demonstrated that individual target-distractor associations were learned in contextual cuing. We examined whether individual associations can be learned in efficient visual searches that do not involve attentional deployment to...
The Role of Memory and Restricted Context in Repeated Visual Search
Previous studies have shown that the efficiency of visual search does not improve when participants search through the same unchanging display for hundreds of trials (repeated search), even though the participants have a clear memory of the search display....
Trajectory Forms as Information for Visual Event Recognition: 3-D Perspectives on Path Shape and Speed Profile
Trajectory forms in events consist of the path shape and the speed profile (Bingham, 1987, 1995). Wickelgren and Bingham (2004) showed that adults can use the speed profile as visual information to recognize events from different perspectives, despite...
Type I Error Rates and Power Analyses for Single-Point Sensitivity Measures
Experiments often produce a hit rate and a false alarm rate in each of two conditions. These response rates are summarized into a single-point sensitivity measure such as d', and t tests are conducted to test for experimental effects. Using large-scale...
Visual Short-Term Memory Operates More Efficiently on Boundary Features Than on Surface Features
A change detection task was used to estimate the visual short-term memory storage capacity for either the orientation or the size of objects. On each trial, several objects were briefly presented, followed by a blank interval and then by a second display...
