Book review: Written and Spoken Language Development across the Lifespan

Abstract

This exploratory study aimed to evaluate the predictive power of graphomotor measures of handwriting taken in Grade 1 of Primary School. The study was developed in two phases. In the first phase, 17 first graders (8 boys, 9 girls, right-handed) copied a list words on a piece of paper attached to a digitiser, in order to collect graphomotor information during handwriting execution. We collected data in three different moments throughout the academic course. We measured Time (Execution time, Writing time, InAir time, in seconds); Trajectory (cm); Disfluency (number of velocity peaks per word); Pressure; and Gazelifts (number of gazes to the stimuli). We ran the second phase when participants were at 5th Grade of Primary School. Firstly, we clustered participants according to the results obtained in Grade 1 on Writing time and Disfluency. Cluster 1 grouped the participants that wrote faster and fluentl
