Contour interpolation by vector-field combination.

We model the visual interpolation of missing contours by extending contour fragments under a smoothness constraint. Interpolated trajectories result from an algorithm that computes the vector sum of two fields corresponding to different unification ...

An evaluation of two commonly used tests of unfamiliar face recognition.

The Warrington Recognition Memory for Faces (RMF) and the Benton Facial Recognition Test (BFRT) are commercially available tests that are commonly used by clinicians and cognitive neuropsychologists to evaluate unfamiliar face recognition. Yet, it is not ...

Illumination encoding in face recognition: effect of position shift.

Recognition of faces and objects is impaired when illumination direction varies. Three experiments explore whether this impairment can be explained by display changes (Biederman & Bar, 1999), and whether cast shadows help or hinder face recognition. ...

Do intersections serve as basic features in visual search?

The status of intersection as a basic feature in visual search tasks has been controversial. Under some circumstances, a target possessing this attribute (eg a plus) pops out of a display of distractors that lack the attribute (eg Ls). However, those ...

Perception of plane orientation from self-generated and passively observed optic flow.

We investigated the perception of three-dimensional plane orientation--focusing on the perception of tilt--from optic flow generated by the observers active movement around a simulated stationary object, and compared the performance to that of an ...

Differences in word associations to pictures and words.

Normal subjects were asked to produce the "first word that comes to mind" in response to pictures or words that differed with respect to manipulability and animacy. In separate analyses across subjects and items, normal subjects produced a significantly ...

Extrinsic cues aid shape recognition from novel viewpoints.

It has been shown previously that the visual recognition of shape is susceptible to the mismatch between the retinal input and its representation in long-term memory, especially when this mismatch arises from rotations in depth. One possibility is that ...

Configural biases and reversible figures: evidence of multilevel grouping effects.

Four experiments sought to identify the processes underlying 2 classes of grouping effects that are readily produced with a hierarchical figure type known as ambiguous triangles. Previous work has shown that aligning small equilateral triangles in ...

Perceptual learning of temporal structure.

We investigated the extent to which the ability to perceive spatial form from temporal structure (TS) improves with practice. Observers trained monocularly for a number of consecutive days on a shape discrimination task, with one group of observers ...

Learned perceptual associations influence visuomotor programming under limited conditions: kinematic consistency.

Previous findings have suggested that visuomotor programming can make use of learned size information in experimental paradigms where movement kinematics are quite consistent from trial to trial. The present experiment was designed to test whether or not ...
