Direct answer

In (Boyle, 2024), CTMT-2 performance showed significant correlations with Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V) Processing Speed Index (PSI) scores. Multiple regression analyses indicated that CTMT-2 trails significantly predicted PSI scores in a sample of school-aged children and adolescents (N = 30, ages 8–15).

Why processing speed matters here

Processing speed indices capture how quickly a child completes timed cognitive tasks. Trail-making tests also depend on speeded visual search and sequencing. Boyle’s abstract places PSI among the cognitive ability outcomes tied to CTMT-2 performance—alongside TEA-Ch2 attention indices.
