Construct validity of the Trail Making Test: Role of task-switching, working memory, inhibition/interference control, and visuomotor abilities

Abstract: The aim of this study was to clarify which cognitive mechanisms underlie Trail Making Test (TMT) direct and derived scores. A comprehensive review of the literature on the topic was carried out to clarify which cognitive factors had been related to TMT performance. Following the review, we explored the relative contribution from working memory, inhibition/interference control, task-switching ability, and visuomotor speed to TMT performance. Forty-one healthy old subjects participated in the study and performed… Show more

“…In addition, eye movements (as potential indicators as to where attention had been allocated) have previously been shown to be similar in the speed and interactivity rating tasks, as well as in control and experimental stimuli in typical participants (Schultz et al 2005). Moreover, both our groups did not differ in the Trail Making Test (TMT), a test of visuospatial attention, which also involves mental flexibility and attentional set-shifting abilities (Reitan 1958;Sánchez-Cubillo et al 2009). Performance on the TMT did not show a significant correlation with the social motion experiment, nor did it account for TPJ gray matter in the ASD or control group.…”

“…The SMART is an integrative training that aims to improve multiple domains of cognitive functions such as abstract reasoning, goal management, and selective attention (Vas et al., 2011). The number–letter switching versus motor speed of the trail‐making test measures cognitive processing speed, working memory, and the ability to switch tasks while maintaining a goal (Sánchez‐Cubillo et al., 2009). Although improvements in cognitive functions following the SMART for TBI can reflect improvement in the trail‐making test scores, the trail‐making test does not measure the same level of cognitive functions that the SMART improves.…”

“…The TMT-A requires the participant to join together a series of points in numerical order while the TMT-B requires the participant to join together a series of points alternating between numerical and alphabetical order. Performance on the trail making test is thought to be influenced by a number of cognitive processes including task switching, attention and executive control in the TMT-B and processing speed in the TMT-A, many of the same components thought to be involved in complex span task performance and hence, language recognition (see for example, Sánchez-Cubillo et al, 2009). …”
