Attentional Mechanisms in Visual Signal Detection: The Effects of Simultaneous and Delayed Noise and Pattern Masks
The attentional cuing effects in detection and some discrimination tasks depend on the use of backward masks and on the presence of external noise in the display. These effects have been attributed to an interruption masking mechanism, which terminates...
Dividing Attention between Two Different Categories and Locations in Rapid Serial Visual Presentations
When two targets are embedded in a rapid serial visual presentation (RSVP) stream of abstractors, perception of the second target is impaired if the intertarget lag is relatively short (less than 500 msec). This phenomenon, called attentional blink,...
Harmonic Expectation and Affect in Western Music: Effects of Attention and Training
We investigated the effects of selective attention and musical training on the processing of harmonic expectations. In Experiment 1, participants with and without musical training were required to respond to the contour of melodies as they were presented...
Hits and False Positives in Face Matching: A Familiarity-Based Dissociation
In recognition memory for unfamiliar faces, performance for target-present items (hits) does not correlate with performance for target-absent items (false positives), a result which runs counter to the more usual mirror effect. In this paper we examine...
Ignorance Is Bliss: The Role of Observer Expectation in Dynamic Spatial Tuning of the Attentional Focus
When two sequential targets (T1, T2) are inserted in an RSVP stream of abstractors, perception of T2 is impaired at intertarget lags shorter than 700 msec. Paradoxically, this deficit disappears when T2 is presented directly after T1 (lag-1 sparing)....
Impact of Contingency Manipulations on Accessory Stimulus Effects
Accessory tone stimuli facilitate response performance despite being irrelevant for the current task. In order to investigate which processes are affected by accessory stimuli, we presented accessory tones in a simple response time (RT) task while varying...
In Sight, out of Mind: The Role of Eye Movements in the Rapid Resumption of Visual Search
Three experiments investigated the role of eye movements in the rapid resumption of an interrupted search. Passive monitoring of eye position in Experiment 1 showed that rapid resumption was associated with a short distance between the eye and the target...
Natural Scene Categorization with Minimal Attention: Evidence from Negative Priming
Research has demonstrated that objects in natural scenes are categorized without the deployment of attention. However, in these types of studies, participants were required to directly respond to peripherally presented scenes, which might lead some participants...
Nonverbal Arithmetic in Humans: Light from Noise
Animal and human data suggest the existence of a cross-species system of analog number representation (e.g., Cordes, Gelman, Gallistel, & Whalen, 2001; Meck & Church, 1983), which may mediate the computation of statistical regularities in the...
Parallel and Serial Search in Haptics
We propose a model that distinguishes between parallel and serial search in haptics. To test this model, participants performed three haptic search experiments in which a target and distractors were presented to their fingertips. The participants indicated...
Preparation for Horizontal or Vertical Dimensions Affects the Right-Left Prevalence Effect
When stimulus and response simultaneously vary in both horizontal and vertical dimensions, the stimulus-response compatibility effect is often larger for the horizontal dimension. We investigated the role of preparation for each dimension in this right-left...
Similarity Structure in Visual Speech Perception and Optical Phonetic Signals
A complete understanding of visual phonetic perception (lipreading) requires linking perceptual effects to physical stimulus properties. However, the talking face is a highly complex stimulus, affording innumerable possible physical measurements. In...
Stimulus and Response Priming in Rapid Serial Visual Presentation: Evidence for a Dissociation
Two experiments investigated the capacity demands of stimulus and response priming in a rapid serial visual presentation (RSVP) task. Three targets were presented in a stream of visual symbols: The first two (T1 and T2) required an unspeeded manual response...
The Absence of an Auditory-Visual Attentional Blink Is Not Due to Echoic Memory
The second of two targets is often missed when presented shortly after the first target-a phenomenon referred to as the attentional blink (AB). Whereas the AB is a robust phenomenon within sensory modalities, the evidence for cross-modal ABs is rather...
The Concavity Effect Is a Compound of Local and Global Effects
Using a change detection paradigm, Barenholtz, Cohen, Feldman, and Singh (2003) found that changes in concave regions of a contour are more easily detected than changes in convex regions. In a series of three experiments, we investigated this concavity...
The Effect of Amplitude Modulation on Intelligibility of Time-Varying Sinusoidal Speech in Children and Adults
Although researchers are currently studying auditory object formation in adults, little is known about the development of this phenomenon in children. Amplitude modulation has been suggested as one of the characteristics of the speech signal that allows...
The Perception of Scatterplots
Four experiments investigated the perception of correlations from scatterplots. All graphic properties, other than error variance, that have been shown to affect subjective but not objective correlation (r) were held constant. Participants in Experiment...
What Influences Visual Search Efficiency? Disentangling Contributions of Preattentive and Postattentive Processes
The present experiments introduce a new search technique for disentangling contributions of preattentive guidance and postattentive template matching to search efficiency. Participants performed searches (for negative or positive faces in Experiment...
