Modelling the use of the tool for the automatic analysis of syntactic sophistication and complexity (TAASSC)

This methods tutorial introduces the Tool for the Automatic Analysis of Syntactic Sophistication and Complexity (TAASSC), a linguistic analysis tool developed by Kyle (2016). In the first part, the tutorial offers an accessible introduction to the key concepts and considerations for using the syntactic complexity and sophistication measures provided by TAASSC. It also overviews the incorporation of new lexico-grammatical features in more recent versions of TAASSC and compares the new versions with earlier versions. The second part of the tutorial guides users through the tool's application by demonstrating a case study of applying TAASSC to a linguistic analysis. It details the process of utilising TAASSC to obtain initial index profiles and conducting mixed-effects modelling using R. The focus is on analysing one aspect of the phrasal complexity development in British school children's writing across academic years, employing mixed-effects models to account for complex data structures and observation interdependence. This tutorial equips researchers with the knowledge to effectively employ TAASSC in linguistic analysis and showcases its utility in exploring syntactic complexity development.
