Full textAbstract:
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 analysis demonstrated a visual perceptual factor, with loadings on the Gollin test and design copying and three other factors representing primary memory, secondary memory, and language Results indicate the Gollin test measures visual perceptual ability, but the precise nature of the task requires further study. Identification of fragmented pictures appears a practical and potentially useful measure for evaluating at least some aspects of visual perception in patients with generalized cognitive impairment.

Full textAbstract:
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 perceptual and attentional processing; screeners' time on the job; screeners' work schedules; and their use of pharmaceuticals, over-the-counter drugs, and dietary supplements. Potential applications of the findings for improving screener performance through personnel selection, training, workforce management, and X-ray equipment design enhancements are discussed. Ongoing research is also outlined.

Full textAbstract:
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 periodicals portal, which covers both Brazilian and international databases. Results: at the end of the search, 72 published articles were selected and analyzed in their entirety. The four most widely used correction systems were the Koppitz System, Gradual Scoring System, Qualitative Classification System, and Global Classification System. Brazil, Peru and the United States were the countries with the highest number of studies. The predominant objectives were the evaluation of the psychometric properties of correction systems and the use of the Bender test to predict possible learning difficulties, especially in reading and writing. Conclusion: suggested prospects for future Bender test studies are reviews of studies developed with an emotional focus, and the addition of other research databases.

Full textAbstract:
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. Intelligence correlated with tasks that required the identification of a confusable target, tasks in which the target was defined by a conjunction of features, and tasks in which the target was defined by its location. Intelligence did not correlate with the ability to identify single targets or targets defined by a single non-confusable feature. Other studies have shown that when attentional load is increased by increasing the number of characters in the display, performance is affected differently for confusable and conjunction targets. Increasing the attentional load reduces the number of hits in the confusable condition and increases the number of false alarms in the conjunction condition. In this study these two measures correlated with intelligence but not with each other, meaning that they assess different aspects of visual perceptual processing efficiency. We conclude that when it is critical to correctly identify targets and to avoid false alarms when monitoring complex displays, targets should not be confusable and should be defined by a single feature. When this is not possible, it is important to select operators who are more efficient at processing confusable and conjunction-defined stimuli.

Full textAbstract:
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 the question of how closely related face aftereffects are to traditional ones. Little is known about the build-up and decay of the face aftereffect, and the similarity of these dynamic processes to traditional aftereffects might provide insight into this relationship. We examined the effect of varying the duration of both the adapting and test stimuli on the magnitude of perceived distortions in face identity. We found that, just as with traditional aftereffects, the identity aftereffect grew logarithmically stronger as a function of adaptation time and exponentially weaker as a function of test duration. Even the subtle aspects of these dynamics, such as the power-law relationship between the adapting and test durations, closely resembled that of other aftereffects. These results were obtained with two different sets of face stimuli that differed greatly in their low-level properties. We postulate that the mechanisms governing these shared dynamics may be dissociable from the responses of feature-selective neurons in the early visual cortex.

Full textAbstract:
Three groups of neuropsychiatric out-patients, homogeneous according to parameters of violent behaviour, were identified in a previous study using a cluster analysis procedure and compared in this study on psychometric variables. These groups were (a) a group manifesting frequent, impulsive violence (n= 35), (b) a non-violent group (n= 57), and (c) a group whose violent behaviour was much less frequent and severe than in the first group, and more provoked (n= 31). Impulsively violent patients showed language and visual-perceptual deficits, but no other neuropsychological or intellectual deficits. The MMPI F, K and Ma and MacAndrews Alcoholism scales and a perceptual organisation factor derived from the Holtzman Inkblot Test significantly discriminated groups. Results of this and the initial study have implications regarding psychological aspects of aggression and underlying biological mechanisms.

Full textAbstract:
The Occupational Therapy Adult Perceptual Screening Test (OT-APST) is designed to screen for impairments in visual perception and apraxia in adults following stroke. The OT-APST is a comprehensive battery that contains 25 items in the following seven subscale areas: agnosia (5 items); visuospatial relations covering elements of body scheme (4 items) and unilateral neglect (5 items); constructional skills (3 items); apraxia (6 items); acalculia (1 item); and functional skills (5 items). Several OT-APST items contribute to more than one subscale, hence there is a difference in the number of items in each subscale and the overall number of items. This study reports three aspects of the reliability of the OT-APST: interrater, intrarater and test-retest reliability. The participants in the interrater and intrarater reliability study were 15 people following stroke. Videotaped OT-APST performance was scored by nine occupational therapists and the results compared with the scores of the first author as the gold-standard rater. The participants in the test-retest reliability study were 10 people who were neurologically stable one year after stroke and were assessed 2 weeks apart on the OT-APST. The results obtained for each of the 25 OT-APST items included intraclass correlation coefficients (Type 3,1) for interrater reliability ranging from 0.66 to 1.0, for intrarater reliability ranging from 0.64 to 1.0, and for test-retest reliability ranging from 0.76 to 0.95. These results indicate that the OT-APST has good interrater, intrarater and test-retest reliability and offers a reliable screening tool for use by occupational therapists working in the area of stroke.

Full textAbstract:
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. The aim of the research is to examine the effectiveness of the experimental program named the Impact of Verbal, Auditory and Visual Incentives, designed to foster students' visual perception and visual reception during art education. Methods. The experimental method with parallel groups was used. The research included the sample consisting of 98 students, out of which 45 belonged to experimental group while 53 were control students from Trebinje region. Test LV1, examining visual creativity, as well as visual perception and visual reception (art appreciation), was used. Results. The results indicated that the experimental program influenced the development of the visual perceptive (F = 3.76; p = 0.05) and visual receptive (F = 8.01; p = 0.00) abilities among students during art education because the experimental group students achieved significantly better results than the control group students. The experimental program was aligned with the curriculum and designed to influence the development of students' visual-perceptual and visual-receptive abilities. Conclusion. The obtained results indicate that it is possible to influence the development of students' visual-perceptual and visual-receptive abilities by using a specially designed program, aimed at stimulating verbal, auditory and visual aspects of visual expression.

Full textAbstract:
The Rivermead Perceptual Assessment Battery (RPAB) is designed to assess visual perception deficits in people suffering from stroke and head Injury. It Is one of the few standardised perceptual assessments specifically developed for occupational therapists. This article examines some aspects of the statistical background of the RPAB. The RPAB authors have reported limited statistical data, which Is Insufficient to understand fully the clinical usefulness of this assessment tool. Reliability and validity are examined and the implications of test results are discussed. The true score range for patients on each subtest is calculated, as well as the amount of change over time required before clinicians can be confident that such change represents a real improvement or decline In the patient's ability. Further, the discriminative power of each subtest is examined, as are the criteria for determining the presence and type of perceptual deficit. These statistical analyses were based on the data reported in the test's manual, as well as from patients assessed at The Prince Henry Hospital, Sydney, over a 2-year period.

Full textAbstract:
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. We hypothesize that there are other, perhaps equally important abilities ON WHICH INDIVIDUALS DIFFER, and we refer to them collectively as temporal visual factors. These are visual functions that operate faster (neurally) than static acuity and support such activities as real and apparent motion perception. We propose to report on the recent development of a computerized temporal acuity test battery. Separate empirical studies at three universities will describe how the different tests are shown to be stable over repeated measures, have high (r > .707) retest reliability, are factorially rich, and are largely uncorrelated with spatial acuity and intelligence. The tests all work on a 386PC, or better, and are transportable by disk.
