Attention parameters in visual search tasks in different age groups.
10 May 2009 
Attention processes were studied using a model based on visual searches for a specified element in grids of size 3 x 3 and 7 x 7 cm displayed on a monitor screen. Five age groups took part in the experimental studies: children of five and seven ...

4 May 2009 PURPOSE: To determine whether visual experience can alter ocular shape and peripheral refractive error pattern, the authors investigated the effects of form deprivation on refractive development in infant rhesus monkeys. METHODS: Monocular form ...

Core knowledge and its limits: the domain of food.
3 May 2009 Adults, preschool children, and nonhuman primates detect and categorize food objects according to substance information, conveyed primarily by color and texture. In contrast, they perceive and categorize artifacts primarily by shape and rigidity. ...

Effects of age, viewing distance and target complexity on static ocular counterroll.
May 2009 The ocular counterroll (OCR) reflex generates partially compensatory torsional eye movements during static head roll tilt. We assessed the influence of age, viewing distance and target complexity on the OCR across the age span (13-63 years; n=47), ...

Do patients with schizophrenia attribute mental states in a referential communication task?
29 Apr 2009 INTRODUCTION: Many studies have reported that individuals with schizophrenia (SZ) may have impaired social cognition, resulting in communication disorders and theory of mind (ToM) impairments. However, the classical tasks used to assess impaired ToM ...

29 Apr 2009 The ability to use the geometric shape of an environment as an orienting cue for goal location has been shown in many vertebrate groups. Experimentally, however, geometric spatial tasks are typically carried out on horizontal surfaces. The present ...

29 Apr 2009 Humans appear extremely sensitive to biologically threatening stimuli, such as snakes. In visual search tasks, humans respond to pictures of snakes faster than pictures of flowers. The authors report that macaque monkeys (Macaca fuscata), reared in ...

Cortical oscillatory activity associated with the perception of illusory and real visual contours.
22 Apr 2009 We used magnetoencephalography (MEG) to examine the nature of oscillatory brain rhythms when passively viewing both illusory and real visual contours. Three stimuli were employed: a Kanizsa triangle; a Kanizsa triangle with a real triangular contour ...

Stereoscopic shape discrimination is well preserved across changes in object size.
20 Apr 2009 A single experiment evaluated human observers' ability to discriminate the shape of solid objects that varied in size and orientation in depth. The object shapes were defined by binocular disparity, Lambertian shading, and texture. The object ...

Binocular properties of curvature-encoding mechanisms revealed through two shape after-effects.
15 Apr 2009 We investigated the binocular properties of curvature-encoding mechanisms using the shape-frequency and shape-amplitude after-effects (or SFAE and SAAE). The SFAE and SAAE refer to the shifts observed in, respectively, the shape-frequency and ...
