Abstract:

Our study was designed to evaluate perceptual ability measured by the Gollin Incomplete Pictures Test (in which subjects identify fragmented pictures of common objects) in Alzheimer Disease. We developed a standardized procedure for administering Gollin's test and compared the performance of 58 Alzheimer patients and 37 elderly controls on the Gollin, two design copying tests, the Mini-Mental State Examination, a verbal version of the Knox Cubes test, a recognition memory test, and a verbal fluency test. Alzheimer patients performed significantly more poorly than controls on all tests. Factor

Abstract:

An airport X-ray Screener Test Battery was developed to better understand how selected aspects of screeners' visual and perceptual capabilities, attentional and verbal processing, work schedule, medication use, work history, training, equipment knowledge, personal style, attitudinal characteristics, and job satisfaction are related to job performance. The Test Battery was administered to 92 X-ray screeners and analyses compared Test Battery performance with X-ray screening job performance. Analyses suggest that important factors related to X-ray screening performance include several aspects of

Abstract:

Background: the Bender test, developed by Lauretta Bender, is intended to evaluate children’s perceptual maturity. Because the instrument lacks a standardized correction system, other researchers have designed different systems for this purpose at distinct periods. Objective: for the present research, we reviewed articles that included the Bender test to identify the most widely used correction systems. Method: eligibility criteria included the instrument application in children up to 10 years of age, focusing on evaluating cognitive aspects. Searches were carried out through the CAPES periodi

Researchers have found little evidence that the ability to identify briefly presented simple stimuli (single letters, symbols) is related to intelligence in normal populations although performance on visual processing tasks which impose a greater attentional load (words, phrases, sentences) has been found to correlate with scores on reading tests. This study assessed the correlation between performance on seven visual processing tasks and intelligence as measured by the Raven's and the Nelson-Denny Reading Test.

Abstract:

Several recent demonstrations using visual adaptation have revealed high-level aftereffects for complex patterns including faces. While traditional aftereffects involve perceptual distortion of simple attributes such as orientation or colour that are processed early in the visual cortical hierarchy, face adaptation affects perceived identity and expression, which are thought to be products of higher-order processing. And, unlike most simple aftereffects, those involving faces are robust to changes in scale, position and orientation between the adapting and test stimuli. These differences raise

Introduction. Art reception and experiencing is a complex process, containing creative components. The experience of a work of art involves reproduction, in the viewer's consciousness, of the experiences and excitement that the artist himself or herself have undergone in the process of creating the same works of art. When viewing visual images, our perception is directed towards the identification of objects, and when viewing visual images as works of art, we also tend to experience them - we subjectively react to elements, such as stylistic and structural characteristics.

Abstract:

Traditionally, sensory, perceptual, and cognitive psychology were normative fields of study where investigators were interested in those aspects of the responses that are normal (common, shared). In the 70's a “new look” emerged where individual dserences were emphasized and paradigms were developed. The predicate for the work reported here follows from the notion that people with better spatial abilities often perform better in jobs that require such skills, while static vision acuity relates to the perception of small spots, fine lines, and grids.

Conceptual art presents an important challenge for neuroaesthetics. Such art helps to stimulate complex psychological events—beyond the perceptual responses usually studied by neuroscience.

Previous studies had shown that the induction segment will bias operant judgments of collinearity for a test segment, this effect being a function of the relative angle between the two. S

Contrasted to these mathematical approaches are various ad hoc measures based on different aspects of structure, which can work

However, some studies suggest PAC improves attention, while others maintain that PAC inhibits attention.

The phenomenon of visual occlusion has frequently been studied by means of two-dimensional line drawings. These drawings may elicit various interpretations. Sometimes a mosaic of shapes is seen, sometimes a shape that partly occludes another shape. In the latter case, observers often have a clear idea about the form of the partly occluded shape. Local and global pattern aspects both seem to be decisive with respect to the preferred interpretation.

Abstract:

The concept that handwriting is primarily a perceptual-motor act is held by various authors (Chapman & Wedell, 1972; Furner, 1969; Sovick, 1975; Ziviani, Hayes, & Chant, 1990). However, the assumption that poor handwriters would perform less well than good handwriters on perceptual-motor tests has not yet been well researched. The purpose of this study was to examine this assumption as well as the relationship of perceptual-motor abilities to the legibility of handwriting. One hundred forty-three Chinese children in grades 3 through 5 served as subjects. Perceptual-motor tests that mea

Abstract:

This study investigated the relationships between personality and creativity in the perception of two different ambiguous visual illusions. Previous research has suggested that Industriousness and Openness/Intellect (as measured by the Big Five Aspects Scale) are both associated with individual differences in perceptual switching rates for binocular rivalry stimuli. Here, we examined whether these relationships generalise to the Necker Cube and the Spinning Dancer illusions. In the experimental phase of this study, participants viewed these ambiguous figures under both static and dynamic, as w

Abstract:

The author considers research into allegedly supernatural “Electronic Voice Phenomena” (EVP) in light of both anecdotal reports and formal experimental studies of related aspects of human auditory perception. He offers the primary hypothesis that an understanding of the relevant aspects of psychoacoustics provides a complete explanation for most EVP recordings, and a secondary hypothesis that an informed understanding of these processes is as relevant to the emergent field of sound art as studies of optical illusions have been to the study of visual art.

Abstract:

Patients who have hemispatial visual neglect (HVN) have difficulty directing their attention toward the visual field contralateral to the side of the lesion. This affects their performance on perceptual assessment tests and masks related visual perceptual deficits. The aim of this study was to verify whether a vertical position of the answer cards of the Motor Free Visual Perceptual Test (MVPT) could overcome this problem. Three groups of subjects were involved in the study: 15 healthy subjects, 15 subjects who had right brain damage without HVN, and 9 subjects who had right brain damage with

Abstract:

This study examined the effectiveness of visual-perceptual training for improving fielding performance in cricket. Twelve highly-skilled cricket players completed a video-based decision-making test and an in-situ fielding test before and after a six-week training intervention. During this period, all participants completed the same on-field training program, but seven players completed three additional perceptual training sessions per week (TRAIN). The remaining five players acted as a control (CON). Despite no group differences at pre-test, TRAIN scored significantly higher than CON at post-t

Abstract:

Ambiguous visual stimuli provide the brain with sensory information that contains conflicting evidence for multiple mutually exclusive interpretations. Two distinct aspects of the phenomenological experience associated with viewing ambiguous visual stimuli are the apparent stability of perception whenever one perceptual interpretation is dominant, and the instability of perception that causes perceptual dominance to alternate between perceptual interpretations upon extended viewing. This review summarizes several ways in which contextual information can help the brain resolve visual ambiguitie

Abstract:

A major element in expert sports performance, particularly racket-and-ball games, is excellent anticipatory skill. A prestudy combined the temporal and spatial occlusion paradigms to ascertain which key stimuli badminton players use for anticipating the direction of overhead shots. The main study then evaluated a program for training anticipatory skills; 200 video clips were employed to orient attention toward these key stimuli. Participants were 63 badminton novices, 20 national league players, and 21 local league players. A transparent red patch (exogenous orienting) was used to orient atten

Abstract:

The results of an experiment are discussed that address how best to train perceptual-rule based skills within a domain where rules correlate to perceptual aspects of a dynamic evolving environment. Participants performed the role of football quarterback where the object of the task was to learn to identify the correct pass receiver in a simulated football system. The correct receiver could always be specified by a set of rules or subtle perceptual cues. Subjects were assigned to one of four training groups which were constructed by complete crossing of rule versus no rule learning and visual e

Abstract:

We propose a new method for assessing the perceptual organization of information graphics, based on the premise that the visual structure of an image should match the structure of the data it is intended to convey. The core of our method is a new formal model of one type of perceptual structure, based on classical machine vision techniques for analyzing an image at multiple resolutions. The model takes as input an arbitrary grayscale image and returns a lattice structure describing the visual organization of the image. We show how this model captures several aspects of traditional design aesth

Abstract:

The present study investigated lateralization of perceptual closure ability. A zero-power, partially occluded, soft contact-lens system was used to lateralize visual input. This technique has been shown to create reliable artificial visual-field deficits when used in situations offering unlimited duration of stimulus exposure. The Street Gestalt Completion Test was administered to 18 right-handed men with no history of head trauma, neurological disorders, or familial sinistrality. Using repeated-measures analyses, and controlling for age, we found no significant hemispheric advantage for eithe

Abstract:

A mental image is in many ways analogous to a percept but it is not completely identical to it. In some respects, visual perception and visual imagery work in different ways. One area which is worth examining with regard to similarities and asymmetries between perception and imagery is the initial phases of visual information processing. The literature includes some references to the equivalence of imagery and perception in optical illusions, but data are contradictory. In our view, a mental image should not be particularly sensitive to variables which are critical in producing an optical illu

Active and passive perceptual training methods were tested with 30 macular degeneration patients to improve their residual vision. Four different measures assessed improvement: a reading test, the Frostig Figure Ground Test (FFG), the Bender-Bestalt Test, and the Farnsworth-Munsell 100-Hue Test (FM-100). Participants were grouped according to two levels of impairment (moderate or severe) and three training conditions (active, passive, and control) in a 2 x 3 multivariate design. It was expected that the training sessions would improve visual task performance, and that active participants would
