Increased interference from conflicting perspectives and gender differences: A longitudinal study during adolescence

Adolescents need to develop adequate perspective-taking skills to successfully navigate their increasingly complex social environments. This study investigated adolescents’ development of the cognitive processes of egocentric and altercentric interference that influence perspective-taking abilities. Using the Dot Perspective Task, participants’ (N = 803; 50.9% female) egocentric and altercentric interference was measured during 3 consecutive years from 12 to 14 years of age. Linear mixed model analyses showed that whereas overall task performance improved over time, egocentric and altercentric interference increased over time. These results suggest that perspective taking develops at slower rates when there are conflicting perspectives than in situations with no conflict. Moreover, we found that girls showed less egocentric interference than boys. This result provides task-based evidence that supports previous findings of higher self-reported perspective taking in adolescent girls than in adolescent boys.
