Description

This dataset contains three separate worksheets containing data used for Study I, Study II & Study III done for this research. The objective of the present study was to develop and validate a new measure of mental rotation ability for preadolescent and adolescent age groups. Items were conceptualized and constructed based on existing theories. Study I checked the suitability of these items among preadolescent and adolescent age groups. After revisions, Study II was done to evaluate the item properties using item response theory. Subsequently done confirmatory factor analysis provided evidence for the construct validity of the new measure. Finally, Study III was done to standardize the measure and develop age-wise and gender-wise norms for preadolescent and adolescent age groups. Analysis of Variance provided evidence of the age-wise development of the ability. Further, Trajectory Analysis was done to track the developmental trajectory of the ability across the age groups. It was found that mental rotation ability follows a linear trajectory of development across preadolescence and adolescence.
