"2 × 3" Primes Naming "6": Evidence from Masked Priming
It is a common assumption for multiplication-solving models that single-digit multiplications are automatically retrieved. However, the experimental evidence for this is based on paradigms under suspicion. In this research, we employed a new procedure...
Amelioration of Axis-Aligned Motion Bias for Active versus Stationary Judgments of Bilaterally Symmetric Moving Shapes' Final Destinations
Recent research confirms that observers' judgments of projected final destinations of axis-trajectory misaligned moving figures are biased in the direction of primary axis deviation from trajectory, a phenomenon we named the axis-aligned motion (AAM)...
A New Look at Novelty Effects: Guiding Search Away from Old Distractors
We examined whether search is guided to novel distractors. In Experiment 1, subjects searched for a target among one new and a variable number of old distractors. Search displays in Experiment 2 consisted of an equal number of new, old, and familiar...
Color Appearance: Properties of the Uniform Appearance Diagram Derived from Hue and Saturation Scaling
Color appearance can be specified by a procedure of direct hue and saturation scaling. The scaling data can be represented on a 2-D color space termed a uniform appearance diagram (UAD). The orthogonal and bipolar axes of the UAD are based on the four...
Context Influences Holistic Processing of Nonface Objects in the Composite Task
We explored whether holistic-like effects can be observed for nonface objects in novices as a result of the task context. We measured contextually induced congruency effects for novel objects (Greebles) in a sequential matching selective attention task...
Development of Size Constancy in Children: A Test of the Metacognitive Theory
Two studies investigated children's abilities to estimate the sizes of distant objects. Each included a size estimation task and a size-distance knowledge test, which assessed children's understanding of the effects of distance on objects' image sizes...
Editorial
Introducing Tutorial ReviewsThis issue of Attention, Perception, & Psychophysics features the publication of the first of a new series of Tutorial Review articles. We plan to publish one of these per month. Our goal is to create a series of papers...
Even in Correctable Search, Some Types of Rare Targets Are Frequently Missed
Socially important visual search tasks, such as airport baggage screening and tumor detection, place observers in situations where the targets are rare and the consequences of failed detection are substantial. Recent laboratory studies have demonstrated...
Focused Spatial Attention Is Independent of Rapid Resumption of an Interrupted Search
In three experiments, we examined possible relationships between the spatial focus of attention and the rapid resumption of a visual search following a brief interruption. In Experiment 1, we tested the role of involuntary (exogenous) spatial orienting...
Illusory Temporal Order for Stimuli at Different Depth Positions
We used four experiments to examine how the perceived temporal order of two visual stimuli depends on the depth position of the stimuli specified by a binocular disparity cue. When two stimuli were presented simultaneously at different depth positions...
Inhibition of Saccadic Eye Movements to Locations in Spatial Working Memory
Inhibition of return (IOR) refers to a bias against overt and covert attentional orienting toward previously attended locations. According to the reorienting hypothesis, IOR is generated when attention is withdrawn from the attended location and is prevented...
Integration of Multiple Views of Scenes
In two experiments, memory was tested for changes in viewpoints in naturalistic scenes. In the key study condition, participants viewed two images of the same scene from viewpoints 40° apart. There were two other study conditions: The two study images...
Knowledge Alters Visual Contrast Sensitivity
Research has shown that the visual system's sensitivity to variations in luminance (visual contrast) within a particular area of the retina is affected in a bottom-up fashion by the ambient contrast levels in nearby regions. Specifically, changes in...
Lightness Constancy: Ratio Invariance and Luminance Profile
The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields. In some cases, however, a lightness constancy failure...
On the Minimization of Task Switch Costs Following Long-Term Training
Flexible, context-dependent linkages between stimulus and response are fundamental to adaptive behavior. In the present article, we evaluate the limits of this flexibility by exploring the asymptotic efficiency of people's ability to switch between two...
Optic Variables Used to Judge Future Ball Arrival Position in Expert and Novice Soccer Players
Although many studies have looked at the perceptual-cognitive strategies used to make anticipatory judgments in sport, few have examined the informational invariants that our visual system may be attuned to. Using immersive interactive virtual reality...
Processing of Natural Images Is Feedforward: A Simple Behavioral Test
Natural images can be classified so rapidly that it has been suggested that their analysis is based on a first single pass of processing activity through the visuomotor system. We tested this theory in a visuomotor priming task in which speeded pointing...
Stimulus Exposure and Gaze Bias: A Further Test of the Gaze Cascade Model
We tested predictions derived from the gaze cascade model of preference decision making (Shimojo, Simion, Shimojo, & Scheier, 2003; Simion & Shimojo, 2006, 2007). In each trial, participants' eye movements were monitored while they performed...
Tactile Perception of Thermal Diffusivity
The thermal diffusivity of an object is a parameter that controls the rate at which heat is extracted from the hand when it touches that object. It is an important feature for distinguishing materials by means of touch. In order to quantitatively describe...
The Danger of Trial-by-Trial Knowledge of Results in Perceptual Averaging Studies
Revived interest in "intuitive statistics" (Peterson & Beach, 1967) is evident in recent studies concerning the ability of observers to estimate mean size for ensembles of lines or of circles. To put the recent studies in context, and to highlight...
The History of Dipper Functions
Dipper-shaped curves often accurately depict the relationship between a baseline, or "pedestal," magnitude and a just noticeable difference in it. This tutorial traces the 45-year history of the dipper function in auditory and visual psychophysics, focusing...
The Importance of Semantics in Auditory Representations
The purpose of the present study was to examine the nature of auditory representations by manipulating the semantic and physical relationships between auditory objects. On each trial, listeners heard a group of four simultaneous sounds for 1 sec, followed...
