Longitudinal Trajectories of ToM, Separated by Their Developmental Patterns. Note. Participants are colored based on their developmental trajectory between their three measurement points. Participants were grouped based on change scores between the measurement at 3 and 4 years of age and 4 and 5 years of age, respectively. A positive development was participants that had a positive change score between at least two measurements and no negative change scores. Negative development was participants that had at least one negative change score and no positive change scores. Unchanged development had no positive and no negative change scores. Only 33 participants could get a variable change score since only 33 were measured at 5 years of age. Variable development had one positive and one negative change score. Participants measured at 3 and 4 years of age and not 5 years of age could only be grouped into positive, negative, or unchanged, as only one change score could be calculated. ToM scores are jittered with a value between − 0.2 and + 0.2 to make data points better visible (i.e., the only possible scores on the scale are 0, 1, 2, 3, and 4). Age in months is displayed as measured and is therefore not jittered
