Children’s understanding of the subjectivity of intentions - masked by linguistic task demands?

The dataset comprises structured behavioral data obtained from two preregistered developmental studies with preschool children. It includes trial-level performance measures from a novel task assessing children’s understanding of subjective intentions, with discrete response outcomes indicating whether children judged an agent’s actions as intentional under simplified task demands. The dataset includes individual accuracy measures across trials, age in months, and condition labels for task variations designed to minimize linguistic processing demands. Participant demographic information (age group, gender), task sequencing metadata, trial identifiers, and complete metadata on experimental design, stimulus materials, and scoring procedures are provided. Data were collected under standardized developmental testing protocols administered in controlled settings with young children and enable reproducible analyses of age-related differences in the acquisition of advanced Theory of Mind capacities regarding subjective intention understanding.
