A Comparison of Length-Matching and Length-Fractionation Measures of Müller-Lyer Distortions
Two experiments were performed to evaluate the informational equivalence of length-matching (e.g., reproduction) and length-fractionation (e.g., bisection) procedures that are frequently used to quantify geometrical size distortions, such as the Müller-Lyer...
A Spatial Explanation for Synchrony Biases in Perceptual Grouping: Consequences for the Temporal-Binding Hypothesis
If two images are shown in rapid sequential order, they are perceived as a single, fused image. Despite this, recent studies have revealed that fundamental perceptual processes are influenced by extremely brief temporal offsets in stimulus presentation....
Attentional and Perceptual Sources of the Auditory Attentional Blink
When a rapid succession of auditory stimuli is listened to, processing of the second of two successive targets among fillers is often impaired, a phenomenon known as the attentional blink (AB). Three experiments were conducted to examine the role of...
Contributions of Temporal and Place Cues in Pitch Perception in Absolute Pitch Possessors
Pitch perception is determined by both place and temporal cues. To explore whether the manner in which these cues are used differs depending on absolute pitch capability, pitch identification experiments with and without pitch references were conducted...
Do We Hear Size or Sound? Balls Dropped on Plates
The aim of this study is to examine whether it is possible to recover directly the size of an object from the sound of an impact. Specifically, the study is designed to investigate whether listeners can tell the size of a ball from the sound when it...
Efficient Visual Search without Top-Down or Bottom-Up Guidance
Two types of mechanisms have dominated theoretical accounts of efficient visual search. The first are bottom-up processes related to the characteristics of retinotopic feature maps. The second are top-down mechanisms related to feature selection. To...
Equating Tasks and Sustaining Attention in Children and Adults: The Methodological and Theoretical Utility of D' Matching
The present study develops a method to create task equivalency for children and adults in vigilance research. Experiment 1 employed the signal detection index of perceptual sensitivity (d') to calibrate vigilance tasks for 32 children (ages 7-8) and...
Inhibition and Decay of Motor and Nonmotor Priming
Motor responses can be facilitated by congruent visual stimuli and prolonged by incongruent visual stimuli that are made invisible by masking (direct motor priming). Recent studies on direct motor priming showed a reversal of these priming effects when...
Intermittent Visual Information and the Multiple Time Scales of Visual Motor Control of Continuous Isometric Force Production
In an experiment, we examined the effect of intermittency (from 25.6 Hz to 0.2 Hz) of visual information on continuous isometric force production as a function of force level (5%, 10%, 25%, and 50% of maximal voluntary contraction [MVC]). The amount...
Remembering "What" Brings along "Where" in Visual Working Memory
Does a behavioral and anatomical division exist between spatial and object working memory? In this article, we explore this question by testing human participants in simple visual working memory tasks. We compared a condition in which there was no location...
Subordinate-Level Categorization Relies on High Spatial Frequencies to a Greater Degree Than Basic-Level Categorization
In two experiments, category verification of images of common objects at subordinate, basic, and superordinate levels was performed after low-pass spatial filtering, high-pass spatial filtering, 50% phase randomization, or no image manipulation. Both...
The Frequency Effect for Pseudowords in the Lexical Decision Task
Four experiments were designed to investigate whether the frequency of words used to create pseudowords plays an important role in lexical decision. Computational models of the lexical decision task (e.g., the dual route cascaded model and the multiple...
The Onset of Receding Motion Captures Attention: Comment on Franconeri and Simons (2003)
Franconeri & Simons (2003) reported that some but not all types of motion capture attention in a visual search task, ostensibly because some types of motion axe behaviorally significant. In the present article, we argue that a more parsimonious explanation...
The Persistence of Object File Representations
Coherent visual experience of dynamic scenes requires not only that the visual system segment scenes into component objects but that these object representations persist, so that an object can be identified as the same object from an earlier time. Object...
The Phantom Illumination Illusion
A novel brightness illusion in planar patterns is reported. The illusion occurs, for example, when surfaces with a luminance ramp shaded from black to white are positioned on a black homogeneous background, so that each white end of the surfaces faces...
The Specificity of Perceptual Learning in Speech Processing
We conducted four experiments to investigate the specificity of perceptual adjustments made to unusual speech sounds. Dutch listeners heard a female talker produce an ambiguous fricative [?] (between [f] and [s]) in [f]- or [s]-biased lexical contexts....
