What does the Trail Making Test measure?

Trails Making Test (Trails) is a neuropsychological test of visual attention and task switching. It can provide information about visual search speed, scanning, speed of processing, mental flexibility, as well as executive functioning.

Who developed the Trail Making Test?

The Trail Making Test (TMT) was developed by Partington and Leiter in 1938 as a divided attention test, and was origi- nally part of the Army Individual Test Battery (Partington & Leiter, 1949) used by the U.S. Army (Army Individual Tests Battery, 1944).

How did the Trail Making Test originate?

History. The test was created by Ralph Reitan, an American neuropsychologist considered one of the fathers of clinical neuropsychology. The test was used in 1944 for assessing general intelligence, and was part of the Army Individual Test of General Ability.

How do you administer Trail Making tests?

To administer the test, give the test taker the paper with the circles on it, explain the directions and then demonstrate on a sample page how to complete Part A. Then, tell the person to begin the test and time them.

Which area of the brain is used in the trail making task?

frontal lobe
Beside visuomotor and visuoperceptual skills, the trail making test–B (TMT-B) requires mental flexibility to shift between numbers and letters which mainly rely on frontal lobe function (2–5).

What does TMT B measure?

The Trail Making Test – Part B (TMT-B) is a commonly used executive control measure with a known floor effect, limiting the ability to distinguish impairment among individuals unable to complete this task in the standard time limit.

What is MCI of the brain?

Mild cognitive impairment (MCI) is the stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It’s characterized by problems with memory, language, thinking or judgment.

What is Trail Making Test Part B?

Neuropsychological Testing Trail Making Test A provides an assessment of complex attention. This test requires the patient to connect randomly positioned numbered circles in numeric order as quickly as possible. Form B presents the patient with numbered circles and circles with letters.

What is the N back test?

A widely used measure for the assessment of working memory function is the n-back task (Owen et al., 2005). Here, participants are typically instructed to monitor a series of stimuli and to respond whenever a stimulus is presented that is the same as the one presented n trials previously.

What is amnestic mild cognitive impairment?

Amnestic MCI: MCI that primarily affects memory. A person may start to forget important information that he or she would previously have recalled easily, such as appointments, conversations or recent events.

What is the shape trail test?

The TMT is one of the most sensitive and popular tests for identifying mild cognitive impairment and mild dementia 2,3,4,5,6]. It measures the speed for attention, sequencing, mental flexibility, and of visual search and motor function, mainly reflecting the ability of “set shifting” 7,8,9,10].

What is the trail making test?

The Trail Making Test is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy.

What factors affect performance on the trail making test?

The differential contribution of mental tracking, cognitive flexibility, visual search, and motor speed to performance on Parts A and B of the Trail Making Test. Journal of Clinical Psychology. 1998;54:585–591.

How to give a trail Mak test to a patient?

not present Step 1: Give the patient a copy of the Trail Mak pencil. Step 2: Demonstrate the test to the patient usin SAMPLE). Step 3: Time the patient as he or she follows th

Is trail making performance related to working memory performance?

If trail making performance is found to be significantly related to Gf, there are at least two reasons to ask whether the Gf relation is primarily attributable to relations shared with working memory (WM).
