Descriptive comparison Between Previous MST Findings and the Current Results. Note. The Figure includes comparison studies that presented results for all three MST categories (i.e., Cognition, Emotion, and Desire) or equivalent categories as Think/Know instead of Cognition [17] or Affect instead of Emotion [22]. In addition, two comparison studies [22, 59] measured MST at only one timepoint positive relation between proportions of cognition at 3 years of age and ToM at 4 years of age (p = .018). Vocabulary size correlations with ToM revealed that cognition vocabulary at 3 years of age was positively related to ToM the year after (p = .004) and Emotion vocabulary at 3 years of age was related to ToM at 5 years of age (p < .001)
