Visual Perception

591.

Visual search for high-level configural differences as well as low-level critical features is highly efficient early in childhood.

Visual search, or the ability to locate a single target from a field of distractors, is used as a means of assessing the capacity of the visual system with regard to the detection of low-level stimulus dimensions such as color, line orientation, and ...

The insula is not specifically involved in disgust processing: an fMRI study.

fMRI studies have shown that the perception of facial disgust expressions specifically activates the insula. The present fMRI study investigated whether this structure is also involved in the processing of visual stimuli depicting non-mimic disgust ...

Visual marking for search: behavioral and event-related potential analyses.

Visual marking is an attentional mechanism of prioritizing the selection of new static or moving objects via top-down intentional inhibition of old objects [Psychol. Rev. 104 (1997) 90-122]. The present study investigated the operation of visual marking ...

The automatic evaluation of novel stimuli.

From classic theory and research in psychology, we distill a broad theoretical statement that evaluative responding can be immediate, unintentional, implicit, stimulus based, and linked directly to approach and avoidance motives. This statement suggests ...

An event-related potential study on visual perceptual learning under short-term and long-term training conditions.

The present study investigated learning-induced changes of event-related potentials in a visual discrimination task, focusing on making a comparison between short-term and long-term learning perceptual processes. Event-related potentials were recorded ...

Case alternation and length effects in lateralized word recognition: studies of English and Hebrew.

Effects of CaSe AlTeRnAtIoN were studied in two lateralized visual lexical decision experiments. We manipulated word length and letter case (UPPER, lower and MiXeD) in both English (Exp. 1, N=60) and Hebrew (Exp. 2, N=60). The previously reported visual ...

Confidence judgments in childrens and adults event recall and suggestibility.

The present work investigated the role of childrens and adults metacognitive monitoring and control processes for unbiased event recall tasks and for suggestibility. Three studies were conducted in which children and adults indicated their degree of ...

Childrens coordination of force output in a pinch grip task.

This study examined the role of sensorimotor system noise in the organization of the force output of the thumb and index finger and the coordination between the two digits in an isometric pinch grip force task as a function of age (6, 8, 10, 18-22 ...

Additive factors analysis of reaction time with alphanumericals and line orientations as stimuli.

Most additive factors method (AFM) analyses of choice reaction time (CRT) have used alphanumerics whereas tests of single process models have often used line length or line orientation. The suggestion is raised that commonly observed additive effects of ...

Contrast sensitivity to radial frequencies modulated by Jn and jn Bessel profiles.

We measured human contrast sensitivity to radial frequencies modulated by cylindrical (Jo) and spherical (jo) Bessel profiles. We also measured responses to profiles of jo, j1, j2, j4, j8, and j16. Functions were measured three times by at least three of ...
