It wasn't until eugenia was 45 years old, that she finally tried to sing opera. surprisingly to her and her friends, she was quite good. prior to this discovery, the information that eugenia was a good opera singer but no one (including her) knew this, falls into what part of the johari window?

Unknown

Explanation:

The Johari window model is a method designed to improve self-awareness as well as personal development. This technique was developed by American psychologists Joseph Luft and Harry Ingham in 1955. In this model, each person is thought to be represented by four squares on a window pane. Each square contains traits that define the person according to himself or to peers. These four quadrants are open (traits that both the subject and other people recognize), blind (traits that the peers see, but not the subject), hidden (traits that the subject admits to, but the peers do not see) and unknown (traits that neither the subject nor the peers see).

i disagree that there is little difference between adult female development and adult male development. sociological studies comparing female and male pathways to adulthood, revelead that there are sustancial differences between them. particularly, female and male differ from timing of marriage, when they began to live with children and the likelihood of combining wife/husband and parent roles.
