Analysis of Individual Variations in the Classical Horizontal-Vertical Illusion
In the horizontal-vertical illusion (HVI), the length of the vertical line is overestimated, whereas in the bisection illusion (BI), the horizontal bisecting line is expected to be overestimated. Here, only half of our 22 observers showed the expected...

Attentional Capture Decreases When Distractors Remain Visible during Rapid Serial Visual Presentations
The identification of a central visual target is impaired by the onset of a peripheral distractor. This impairment is said to occur because attentional focus is diverted to the peripheral distractor. We examined whether distractor offset would enhance...
Attentional Prioritizations Based on Spatial Probabilities Can Be Maintained on Multiple Moving Objects
Previous studies have shown that attention prioritizes locations that frequently contain a target. The present study examines whether these spatial prioritizations can be maintained on multiple independently moving objects. Observers viewed two line...
Automaticity in Rule-Based and Information-Integration Categorization
Three experiments studied the effects of category structure on the development of categorization automaticity. In Experiment 1, participants were each trained for over 10,000 trials in a simple categorization task with one of three category structures....
Crossmodal Interaction between the Mental Number Line and Peripersonal Haptic Space Representation in Sighted and Blind Individuals
Humans tend to represent numbers in the form of a mental number line. Here we show that the mental number line can modulate the representation of peripersonal haptic space in a crossmodal fashion and that this interaction is not visually mediated. Sighted...
DLs in Reminder and 2AFC Tasks: Data and Models
García-Pérez and Alcalá-Quintana (2010) dispute the conclusion of Lapid, Ulrich, and Rammsayer (2008) that the two-alternative forced choice (2AFC) task yields meaningfully larger estimates of the difference limen (DL) than does the reminder task. García-Pérez...
Even Frequent and Expected Words Are Not Identified without Spatial Attention
Previous studies have disagreed about the extent to which people extract meaning from words presented outside the focus of spatial attention. The present study examined a possible explanation for such discrepancies inspired by attenuation theory: Unattended...
Grouping Processes Underlie Crowding
VISUAL PROCESSINGLivne & Sagi (2010). How do flankers relations affect crowding? J Vis, 10(3): Art. 1.Recent years have witnessed a steep rise in the number of studies focusing on crowding, yet the nature of the mechanisms that bring this phenomenon...
Grouping Puts Figure-Ground Assignment in Context by Constraining Propagation of Edge Assignment
Figure-ground organization involves the assignment of edges to a figural shape on one or the other side of each dividing edge. Established visual cues for edge assignment primarily concern relatively local rather than contextual factors. In the present...
Haptic Perception of Gravitational and Inertial Mass
Mass can be perceived in different ways: statically, through gravitational cues; dynamically, through inertial cues; or a combination of both. This article investigates the relationship between these modes of perception. In three different experiments,...
How Does Attention Spread across Objects Oriented in Depth?
Previous evidence suggests that attention can operate on object-based representations. It is not known whether these representations encode depth information and whether object depth, if encoded, is in viewer- or object-centered coordinates. To examine...
How High Is Visual Short-Term Memory Capacity for Object Layout?
Previous research measuring visual short-term memory (VSTM) suggests that the capacity for representing the layout of objects is fairly high. In four experiments, we further explored the capacity of VSTM for layout of objects, using the change detection...
Metameric Intransitivity
There are two kinds of afterimages. In negative afterimages, looking at a blank field after staring at a colored figure gives a figure whose color is complementary to that of the original figure. Less well understood and studied is the phenomenon of...
Part Perception in Infancy: Sensitivity to the Short-Cut Rule
Research indicates that object perception involves the decomposition of images into parts. A critical principle that governs part decomposition by adults is the short-cut rule, which states that, all else being equal, the visual system parses objects...
Perceiving Action Boundaries: Learning Effects in Perceiving Maximum Jumping-Reach Affordances
Coordinating with another person requires that one can perceive what the other is capable of doing. This ability often benefits from opportunities to practice and learn. Two experiments were conducted in which we investigated perceptual learning in the...
Perception of Intersensory Synchrony: A Tutorial Review
For most multisensory events, observers perceive synchrony among the various senses (vision, audition, touch), despite the naturally occurring lags in arrival and processing times of the different information streams. A substantial amount of research...
Practice-Induced and Sequential Modulations of the Simon Effect
People react more quickly and more accurately to stimuli presented in locations corresponding to the response, as compared with noncorresponding locations, even when stimulus location is irrelevant (Simon effect [SE]). The explanation that SEs are caused...
Reduction of the Flash-Lag Effect in Terms of Active Observation
In the present study, we investigated how observers' control of stimulus change affects temporal and spatial aspects of visual perception. We compared the illusory flash-lag effects for automatic movement of the stimulus with stimulus movement that was...
Reflections on the Early History of Perception & Psychophysics
Perception & Psychophysics was founded in 1966 by Clifford T. Morgan. After World War II (WWII) Cliff had received a faculty appointment at the Johns Hopkins University to build a psychology department. He quickly put together an outstanding faculty,...
Reminder and 2AFC Tasks Provide Similar Estimates of the Difference Limen: A Reanalysis of Data from Lapid, Ulrich, and Rammsayer (2008) and a Discussion of Ulrich and Vorberg (2009)
Lapid, Ulrich, and Rammsayer (2008) reported that estimates of the difference limen (DL) from a two-alternative forced choice (2AFC) task are higher than those obtained from a reminder task. This article reanalyzes their data in order to correct an error...
Spatial Attention Modulates Feature Crosstalk in Visual Word Processing
One major idea about spatial attention is that it serves to modulate crosstalk between features during reading. Two reading aloud experiments are reported in which a cue-validity manipulation was combined with manipulations that are thought to increase...
Task Integration in Time Production
Two experiments examined training on a prospective time production task. Participants produced intervals, expressed in fixed arbitrary units, while performing a concurrent secondary task. After a 15-min filled delay, the participants were retrained on...
The Prioritization of Perceptual Processing in Categorization
In three experiments, the effects of selective attention on perceptual processes in a complex multidimensional object categorization task were investigated. In each experiment, participants completed a perceptual-matching task to gain estimates of the...
The Size of an Attentional Window Affects Working Memory Guidance
We ask whether attentional guidance from working memory (WM) is influenced by the size of an attentional window. Participants adopted either a focused or a diffuse attentional window when responding to a search display. Prior to the search display an...
The Time Course of Configural Change Detection for Novel 3-D Objects
The present study investigated the time course of visual information processing that is responsible for successful object change detection involving the configuration and shape of 3-D novel object parts. Using a one-shot change detection task, we manipulated...
Top-Down Search Strategies Determine Attentional Capture in Visual Search: Behavioral and Electrophysiological Evidence
To investigate how attentional capture in visual search is affected by generalized top-down search strategies, ERPs and behavioral performance were measured in two experiments where spatially nonpredictive color singleton cues preceded visual search...
Video Game Players Show More Precise Multisensory Temporal Processing Abilities
Recent research has demonstrated enhanced visual attention and visual perception in individuals with extensive experience playing action video games. These benefits manifest in several realms, but much remains unknown about the ways in which video game...
