Absolute Localization of Vibrotactile Stimuli on the Torso
Vibrotactile mobility systems present spatial information such as the direction of a waypoint through a localized vibration on the torso. Using these systems requires the ability to determine the absolute location of the stimulus. Because data are available...
A Face Recognition by Similarity (FRBS) Conjecture
Cohen (1963) investigated free recall in two lists of words. The first contained unrelated words. The second comprised words drawn from several semantic categories, where the number of categories was equal to the number of words in the first list. He...
A Role for the Perceptual Representation Memory System in Category Learning
There is growing evidence that working memory, episodic/semantic memory, and procedural memory all play important roles in at least some types of category learning. Little is known, however, about the role of the perceptual representation memory system...
Audiovisual Synchrony and Temporal Order Judgments: Effects of Experimental Method and Stimulus Type
When an audio-visual event is perceived in the natural environment, a physical delay will always occur between the arrival of the leading visual component and that of the trailing auditory component. This natural timing relationship suggests that the...
Backward Recognition Masking as a General Type of Interference in Needed Poststimulus Processing
Auditory backward recognition masking (ABRM) has been argued to reflect interference in the storage and/or processing of a short-lived sensory form of information and has been viewed as a relatively invariant attribute of auditory pitch processing for...
Distinctive Shapes Benefit Short-Term Memory for Color Associations, but Not for Color
In four experiments, we examined the effect of pairing colors with either homogeneous or heterogeneous shapes on a short-term memory task. In Experiment 1, we found no differences in color memory for displays in which colors were each associated with...
Distractor Inhibition Is More Effective at a Central Than at a Peripheral Location
The "distractor eccentricity effect" refers to the finding of reduced interference from an incompatible distractor at a central relative to a peripheral location (Chen, 2008). The present study examines the mechanism that underlies the distractor eccentricity...
Dividing Attention across Feature Dimensions in Statistical Processing of Perceptual Groups
Statistical processing has been shown in the perception of several visual dimensions, including size, speed, direction of motion, and orientation. Chong and Treisman (2005) found no decrement when people simultaneously averaged two sets on a single dimension,...
Modality-Specific and Amodal Sources of Interference in the Attentional Blink
When two masked targets (T1 and T2) are visually or auditorily presented in rapid succession, processing of T1 produces an attentional blink (AB)-that is, a transient impairment of T2 identification. The present study was conducted to compare the relative...
Perceptual Asynchronies between Color and Motion at the Onset of Motion and along the Motion Trajectory
A color change that is physically simultaneous with the onset of object motion may be perceived as occurring before the initial displacement In contrast, a colored flash during object motion is displaced in the direction of motion, suggesting that it...
Perceptual Experience and Posttest Improvements in Perceptual Accuracy and Consistency
Two experiments investigated the relationship between perceptual experience (during practice) and posttest improvements in perceptual accuracy and consistency. Experiment 1 investigated the potential relationship between how often knowledge of results...
Perceptual Learning and the Visual Control of Braking
Performance on a visually guided action may improve with practice because observers become perceptually attuned to more reliable optical information. Fajen and Devaney (2006) investigated perceptual attunement, using an emergency braking task in which...
Poor Shape Perception Is the Reason Reaches-to-Grasp Are Visually Guided Online
Both judgment studies and studies of feedforward reaching have shown that the visual perception of object distance, size, and shape are inaccurate. However, feedback has been shown to calibrate feedfoward reaches-to-grasp to make them accurate with respect...
Practice in Visual Search Produces Decreased Capacity Demands but Increased Distraction
Lavie (1995) proposed a load account of selective attention, which holds that spare capacity is involuntarily allocated to the processing of irrelevant stimuli. In support of this account, Lavie and Cox (1997) combined a letter search task with a flanker...
Probe-Specific Proportion Task Repetition Effects on Switching Costs
In two experiments, participants were presented with successive presentations of animal names (e.g., GORILLA, WHALE)-a prime display followed by a probe display. In response to each display, participants judged either the typical habitat or the relative...
Using Temporal Order to Identify Spatial Reference Frames
A new method for identifying spatial reference frames is described and applied to the study of spatial span. In this method, a spatial sequence is displayed in relation to two reference frames that move relative to each other, so that different temporal...
Visual Search Is Not Blind to Emotion
A series of three visual search tasks revealed more efficient search for hostile than for peaceful faces among neutral face distractors. Given that this effect has been observed inconsistently in prior literature, meta-analytic methods were employed...
