Digital Technology Differentiates Graphomotor and Information Processing Speed Patterns of Behavior.

ABSTRACT:

Background

Coupling digital technology with traditional neuropsychological test performance allows collection of high-precision metrics that can clarify and/or define underlying constructs related to brain and cognition.

Objective

To identify graphomotor and information processing trajectories using a digitally administered version of the Digit Symbol Substitution Test (DSST).

Methods

A subset of Long Life Family Study participants (n = 1,594) completed the DSST. Total time to draw each symbol was divided into 'writing' and non-writing or 'thinking' time. Bayesian clustering grouped participants by change in median time over intervals of eight consecutively drawn symbols across the 90 s test. Clusters were characterized based on sociodemographic characteristics, healt
