Aging and the Perception of 3-D Shape from Dynamic Patterns of Binocular Disparity
In two experiments, we investigated the ability of younger and older observers to perceive and discriminate 3-D shape from static and dynamic patterns of binocular disparity. In both experiments, the younger observers' discrimination accuracies were...
Contribution of Thermal Cues to Material Discrimination and Localization
The objective of these two experiments was to determine the role of thermal cues in material discrimination and localization, using materials that spanned a range of thermal properties. In the first experiment, the subjects were required to select the...
Grouping Does Not Require Attention
Many theories of visual perception stipulate that Gestalt grouping occurs preattentively. Subjects' failure to report perceiving even salient grouping patterns under conditions of inattention challenges this assumption (see, e.g., Mack, Tang, Tuma, Kahn,...
Hearing a Face: Cross-Modal Speaker Matching Using Isolated Visible Speech
An experiment was performed to test whether cross-modal speaker matches could be made using isolated visible speech movement information. Visible speech movements were isolated using a point-light technique. In five conditions, subjects were asked to...
Infants' Perception of Depth from Cast Shadows
Five- and 7-month-old infants viewed displays in which cast shadows provided information that two objects were at different distances. The 7-month-olds reached preferentially for the apparently nearer object under monocular-viewing conditions but exhibited...
Limits on Integrating Motion Information across Saccades
In two experiments, we investigated whether people could detect changes in the rotary motion of a cube. A rendering of a cube rotating at a constant angular velocity was presented on a video monitor and, at a key point in the trial, a cross was presented...
Motion Onset Captures Attention: A Rejoinder to Franconeri and Simons (2005)
Recently, we have provided evidence that the onset of motion captures attention (Abrams & Christ, 2003, 2005a, 2005b). In the present article, we clarify the motion onset hypothesis, we discuss recent data (Franconeri & Simons, 2005) that, at...
Photometric, Geometric, and Perceptual Factors in Illumination-Independent Lightness Constancy
It has been shown that lightness constancy depends on the articulation of the visual field (Agostini & Galmonte, 1999). However, among researchers there is little agreement about the meaning of "articulation." Beyond the terminological heterogeneity,...
Segment Duration as a Cue to Word Boundaries in Spoken-Word Recognition
In two eye-tracking experiments, we examined the degree to which listeners use acoustic cues to word boundaries. Dutch participants listened to ambiguous sentences in which stop-initial words (e.g., pot, jar) were preceded by eens (once); the sentences...
Strength of British English Accents in Altered Listening Conditions
This work is concerned with the processing or representational level at which accent forms learned early in life can change and with whether alteration to a speaker's auditory environment can elicit an original accent. In Experiment 1, recordings were...
The Aesthetic Appeal of Minimal Structures: Judging the Attractiveness of Solutions to Traveling Salesperson Problems
Ormerod and Chronicle (1999) reported that optimal solutions to traveling salesperson problems were judged to be aesthetically more pleasing than poorer solutions and that solutions with more convex hull nodes were rated as better figures. To test these...
The Control of Saccade Trajectories: Direction of Curvature Depends on Prior Knowledge of Target Location and Saccade Latency
Recent reports have shown that saccades can deviate either toward or away from distractors. However, the specific conditions responsible for the change in initial saccade direction are not known. One possibility, examined here, is that the direction...
The Structure of Frontoparallel Haptic Space Is Task Dependent
In three experiments, we investigated the structure of frontoparallel haptic space. In the first experiment, we asked blindfolded participants to rotate a matching bar so that it felt parallel to the reference bar, the bars could be at various positions...
Within-Modality and Cross-Modality Attentional Blinks in a Simple Discrimination Task
Following up on studies of the "attentional blink," we studied interference between successive target stimuli in visual and auditory modalities. In each experiment, stimuli were two tones and four dots, simultaneously presented for 1,800 msec. Targets...
