Nonverbal Syntax Framework: Evidence-Based System for Inferring Learner States
The Nonverbal Syntax Framework (NSF) has been introduced to better understand learners' cognitive and emotional states by looking at their observable behaviors. This framework was developed after analyzing 908 studies and mapping out 17,043 cue-state connections (Turaev et al., 2026). It addresses three key challenges: inconsistent terminology, varying evidence quality, and unclear states. By standardizing, 5,537 state labels were condensed into 2,010 essential states (63.7%), and 11,521 cues were streamlined to 6,434 normalized cues (44.2%) across nine behavioral categories. Additionally, a dual-evidence approach assesses both Component Evidence (cues and states) and Relationship Evidence (separate studies for each cue-state pair), with 52% of these connections rated as having 'Very High' evidence.
