Illusory Motion and Representational Momentum
When a moving target vanishes abruptly, participants judge its final position as being ahead of its actual final position, in the direction of motion (representational momentum; Freyd & Finke, 1984). In the present study, we presented illusory motion...
Incidental Visual Memory for Targets and Distractors in Visual Search
We explored incidental retention of visual details of encountered objects during search. Participants searched for conjunction targets in 32 arrays of 12 pictures of real-world objects and then performed a token discrimination task that examined their...
Location Negative Priming in Identity Discrimination Relies on Location Repetition
Negative priming manifests when a previously ignored stimulus becomes a target. The contingency of identity negative priming on repeated stimuli has been demonstrated, implying a crucial role for distractor competition. In this study, a naming task was...
No Overall Right-Left Prevalence for Horizontal and Vertical Simon Effects
The present study confirmed that there is no overall right-left prevalence effect for Simon tasks, in which stimulus location is irrelevant, when (1) the stimulus and response sets vary along both horizontal and vertical dimensions simultaneously, (2)...
Oculomotor Consequences of Abrupt Object Onsets and Offsets: Onsets Dominate Oculomotor Capture
Previous research has shown that the appearance of an object (onset) and the disappearance of an object (offset) have the ability to influence the allocation of covert attention. To determine whether both onsets and offsets have the ability to influence...
Pacinian Representations of Fine Surface Texture
Subjects were presented with pairs of finely textured stimuli and were instructed to rate their dissimilarity, using free magnitude estimation. The subjects also rated the stimuli along each of four textural continua: roughness, hardness, stickiness,...
Selective Target Processing: Perceptual Load or Distractor Salience?
Perceptual load theory (Lavie, 1995) states that participants cannot engage in focused attention when shown displays containing a low perceptual load, because attentional resources are not exhausted, whereas in high-load displays attention is always...
Statistical Computations over a Speech Stream in a Rodent
Statistical learning is one of the key mechanisms available to human infants and adults when they face the problems of segmenting a speech stream (Saffran, Aslin, & Newport, 1996) and extracting long-distance regularities (Gómez, 2002; Peña, Bonatti,...
The Effect of Target Contrast on the Attentional Blink
In this set of five rapid serial visual presentation experiments, observers identified one or two target letters that were embedded in a stream of distractors. Target contrasts were varied, and their effects on the attentional blink (AB) were examined....
The Ground Dominance Effect in the Perception of 3-D Layout
The relative effectiveness of the ground surface and other environmental surfaces (the ceiling and sidewalls) in determining perceived layout was investigated in five experiments and a real-world demonstration. In the first three experiments, two vertical...
Use of Visual Information in Speech Perception: Evidence for a Visual Rate Effect Both with and without a McGurk Effect
The McGurk effect, where an incongruent visual syllable influences identification of an auditory syllable, does not always occur, suggesting that perceivers sometimes fail to use relevant visual phonetic information. We tested whether another visual...
Variation in Cue Duration Reveals Top-Down Modulation of Involuntary Orienting to Uninformative Symbolic Cues
This article reports three experiments in which the effects of cue duration on involuntary orienting to uninformative symbolic cues (arrows presented at fixation) were investigated. Experiment 1 showed that symbolic cues had less effect on involuntary...
Vibrotactile Intensity and Frequency Information in the Pacinian System: A Psychophysical Model
The objective of the study was to characterize the Pacinian representation of stimulus waveform. Subjects were presented with pairs of high-frequency vibrotactile stimuli that varied in intensity and/or frequency content and made same-different judgments...
When Do Irrelevant Visual Stimuli Impair Processing of Identical Targets?
Three experiments investigated whether the repeated-letter inferiority effect (RLIE) and repetition blindness (RB) are identical phenomena or not and how the RLIE can be reconciled with the flanker compatibility effect (FCE). Participants reported a...
