Perceptual speed (PS) is defined as someone’s speed in comparing figures or symbols, scanning to find figures or symbols, and performing other simple tasks involving visual perception [22].

You might have high perceptual reasoning abilities if you can: Take a computer apart and put it back together. Read a map or find your way around a neighborhood without assistance. Estimate the distance between two objects with ease.

Perceptual Reasoning Index: A measure of an individual’s ability to understand visual information and to solve novel abstract visual problems. Working Memory Index: A measure of an individual’s ability to hold verbal infor- mation in short-term memory and to manipulate that information.

Differences among processing speed tasks are recognized to some extent by the field, namely the division of processing speed into a simpler, motor-weighted factor known as “psychomotor speed” or “sensorimotor speed” or “sensory-motor processes” (essentially, time to complete repetitive motor tasks), and a more-complex.

Perceptual speed and accuracy tests measure the ability to focus attention and quickly process information. The operationalization of perceptual speed and accuracy has typically focused strictly on the number of items correct (NC), for assessing the ability to quickly process information.

Perceptual speed is a cognitive ability defined as “Speed in comparing figures or symbols, scanning to find figures or symbols, or carrying out other very simple tasks involving visual perception” [1].

Perceptual Speed: those who perceive quickly tend to be more intelligent. Neuro: faster cognitive process may allow more information to be acquired. refers to the extent to which a measure represents all facets of a given social construct.

The main difference between aptitude tests and achievement tests is that aptitude tests discard previous formation, while achievement tests assess previous knowledge. That’s why achievement tests are confined to a specific subject or area of knowledge and are usually applied when a grade or level of study has finished.

Processing speed is the pace at which you take in information, make sense of it, and begin to respond. This information can be visual, like letters and numbers. It can also be auditory, like spoken language. Some people have faster processing speed than others.

When any of us feel anxious, we freeze for a moment. During that time, we’re not processing information as fast as we might otherwise be. We may take longer to respond, make decisions, or size up situations. That’s how anxiety can impact processing speed.

Abstract. Cognitive disorders include dementia, amnesia, and delirium. In these disorders, patients are no longer fully oriented to time and space. Depending on the cause, the diagnosis of a cognitive disorder may be temporary or progressive.
