The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
The Benton Visual Retention Test is composed of 3 sets, or forms, of 10 designs (each 8.5 × 5.5 in.) that measure the examinee's visual and memory abilities as well as a set of alternate designs for repeated tests. [4] The examinee is given a booklet containing 10 blank pages on which they reproduce the designs.
The Wechsler Adult Intelligence Scale (WAIS) is an Intelligence Quotient (IQ) test designed to measure intelligence and cognitive ability in adults and older adolescents. [1] For children between the ages of 6 and 16, Wechsler Intelligence Scale for Children (WISC) is commonly used.
[9] This test measures five factors of cognitive ability, which are as follows: "fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing and working memory." [10] Wechsler Adult Intelligence Scale: The Wechsler Adult Intelligence Scale (WAIS) is used to determine and assess the intelligence of the participant. This is one ...
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, and executive functioning. [1] It is sensitive to cognitive impairment associated with dementia , including Alzheimer's disease .
This allows for a person's performance to be compared to a suitable control group, and thus provide a fair assessment of their current cognitive function. According to Larry J. Seidman, the analysis of the wide range of neuropsychological tests can be broken down into four categories.
As computer-human technology improves, future PPVT e-assessments research may include use of visual tracking computer interface such as wearable eye tracking glasses [5] [6] so that disabled adults can respond to PPVT test items by scanning the visual field and fixing their eye gaze on the visual item they select.
