Final answer:
Tania's inconsolable crying after her haircut, believing she looked like a boy, demonstrates a focus on appearance and possibly egocentrism, revealing the weight society places on girls' looks and the challenge of understanding different perspectives.
Step-by-step explanation:
After her haircut was complete, Tania began crying inconsolably and claimed, "You turned me into a boy!" The obstacle to logic that Tania was demonstrating appears to be focus on appearance. This response is related to the societal pressure on young girls to conform to certain standards of beauty, which is highlighted in Lisa Bloom's assertions regarding the importance placed on the appearance of young girls.
Such an intense reaction over a haircut, attributing it to a change in gender identity, indicates an overemphasis on physical appearance as a major contributor to gender identity. In Tania's case, egocentrism could also be at play, considering her belief that her new appearance would be how others define her gender, paralleling the thought process of the egocentric child in Piaget's description who assumes their perspective is shared by others.
