Asymmetric Priming Effects in Visual Processing of Occlusion Patterns
In three experiments, we examined the effect of temporal context in amodal completion of partly occluded nontarget figures. In a primed same-different task, test pairs were preceded by a sequence of two primes, one of which was a single, the other a...
Effects of Search Mode and Intertrial Priming on Singleton Search
There is no consensus as to what information guides search for a singleton target. Does the most salient display element capture attention, regardless of the observer's attentional set? Do observers adopt a default salience-based search mode? Does knowledge...
Feature Mismatch Effects in Auditory Negative Priming: Interference as Dependent on Salient Aspects of Prior Episodes
A handful of studies have revealed that withholding a response to a sound causes impaired responding to that sound when subsequently presented (Buchner & Steffens, 2001; Mondor, Leboe, & Leboe, 2005). In the present study, we investigated whether...
How Attention Enhances Spatial Resolution: Evidence from Selective Adaptation to Spatial Frequency
In this study, we investigated how spatial resolution and covert attention affect performance in a texture segmentation task in which performance peaks at midperiphery and drops at peripheral and central retinal locations. The central impairment is called...
Inefficient Conjunction Search Made Efficient by Concurrent Spoken Delivery of Target Identity
Visual search based on a conjunction of two features typically elicits reaction times that increase linearly as a function of the number of distractors, whereas search based on a single feature is essentially unaffected by set size. These and related...
Object Recognition in Dense Clutter
Observers in recognition experiments invariably view objects against a blank background, whereas observers of real scenes sometimes view objects against dense clutter. In this study, we examined whether an object's background affects the information...
On the Locus of Priming and Inverse Priming Effects
Visual stimuli that are made invisible by a following mask can affect overt motor responses and nonmotor processing. Previous studies have compared the effects of primes that were perceptually similar to the subsequent stimulus with those of primes that...
Reference-Related Inhibition Produces Enhanced Position Discrimination and Fast Repulsion near Axes of Symmetry
Models proposed to account for reference frame effects in spatial cognition often account for performance in some tasks well, but fail to generalize to other tasks. Here, we demonstrate that a new process account of spatial working memory-the dynamic...
Reinstating Object-Based Attention under Positional Certainty: The Importance of Subjective Parsing
Previous studies have shown that interference from flanking abstractors can be modulated by the object organization of the scene. The experiments reported here test for object-based attention under conditions of positional certainty, which allow a narrow...
Selective Attention versus Selection for Action: Negative Priming Is Not the Result of Distractors Being Unattended
Using a novel referent size-selection task, MacDonald, Joordens, and Seergobin (1999; MacDonald & Joordens, 2000) found that negative priming persisted even when participants were encouraged to attend to distractors before selectively responding...
Spatial Frequency Thresholds for Face Recognition When Comparison Faces Are Filtered and Unfiltered
Previous work has shown an advantage of middle spatial frequencies (SFs) in face recognition. However, a few recent studies have suggested that this advantage is reduced when comparison and test stimuli are spatially filtered in a similar way. In the...
The Effects of Category Overlap on Information-Integration and Rule-Based Category Learning
In three experiments, we investigated whether the amount of category overlap constrains the decision strategies used in category learning, and whether such constraints depend on the type of category structures used. Experiments 1 and 2 used a category-learning...
The Influence of Spatial Context and the Role of Intentionality in the Interpretation of Animacy from Motion
We present three experiments investigating how spatial context influences the attribution of animacy to a moving target. Each of our displays contained a moving object (the target) that might, depending on the way it moved, convey the impression that...
Time Perception and Word Recognition: An Elaboration of the Time-Criterion Account
Past research suggests that a time criterion guides responding in speeded word recognition tasks. The time-criterion account has been challenged, however, because it incorrectly predicts equivalent latencies for stimuli of differing difficulty when those...
