Recent controversy surrounds the use of the Trail Making Test as a measure of cognitive flexibility, given that the Trail Making Test, Part B (TMT-B) also differs from Part A (TMT-A) in factors of motor control and perceptual complexity. The present study compared performance in the TMT and a set-switching task in order to test the assumption that cognitive flexibility is captured in TMT-B performance. Set-switching tasks have low motor and perceptual selection demands, and therefore provide a… Expand

Construct validity of the Trail Making Test: Role of task-switching, working memory, inhibition/interference control, and visuomotor abilities
TLDR
The results suggest that T MT-A requires mainly visuoperceptual abilities, TMT-B reflects primarily working memory and secondarily task-switching ability, while B-A minimizes visu operceptual and working memory demands, providing a relatively pure indicator of executive control abilities. Expand
The Trail Making Test, Part B: Cognitive Flexibility or Ability to Maintain Set?
TLDR
Preliminary support is provided for TMT Part B performance being more sensitive to cognitive flexibility than ability to maintain set (operationalized as Wisconsin Card Sorting Test [WCST], percent perseverative errors) than abilityto maintain set. Expand

TLDR
The ability to measure four axes of the speed-precision trade-off inherent in a subject’s fundamental decision making: perceptual-motor speed, executive speed, subject accuracy, and reaction to difficulty is provided. Expand

TLDR
A new TMT-B efficiency metric is proposed designed to capture clinically relevant performance variability below the standard administration floor and has concurrent validity, permits statistical analysis of performances that fall below the test floor, and captures clinicallyrelevant performance variability missed by alternative methods. Expand
The Trail Making Test
TLDR
Normative tables according to significant factors such as age, education level, and sex were created, and measures of visual scanning, graphomotor speed, and visuomotor processing speed were more related to the performance of the TMT-A score, while working memory and inhibition control were mainly associated with the T MT-B and derived TMT scores.

Multicomponent analysis of a digital Trail Making Test
TLDR
Regression analyses with traditional neuropsychological measures revealed that Part A components were best predicted by speeded processing, while inhibitory control and visual/spatial sequencing were predictors of specific components of Part B. Expand

Construct validity in the Trail Making Test: what makes Part B harder?
TLDR
The results indicate that Part B is more difficult than Part A not only because it is a more difficult cognitive task, but also because of its increased demands in motor speed and visual search. Expand

TLDR
The results yielded significant switch cost only for alternating tasks, in both response times and errors resulting from performance of the wrong task, suggesting that task-set inhibition is an important executive control process. Expand

TLDR
The analysis indicates that, in a nonclinical sample, the TMT measures a number of different functions and the observation of impaired performance must be further investigated to ascertain the specific nature of these deficits in order to guide rehabilitation and management planning. Expand

The Trail Making Test A and B: A Technical Note on Structural Nonequivalence
TLDR
The interpretive assumptions that Trail Making B differs from Trail Making A only in terms of the cognitive skills needed to complete the test and the implicit interpretive bias toward minimizing the motor component of the tests were challenged in this technical note. Expand

TLDR
Two measures of relationship between Parts A and B of the Trail Making Test were examined in a large, acute rehabilitation population and found to be correlated highly with intelligence and severity of impairment and, to a lesser degree, with age, education, and memory functioning. Expand
