Emotional development is considered to be one of the most important procesess when it comes to the personality development overall. According to Reeve (2010), emotions can be defined as short-lasting subjective-physiological-expressional phenomenons that mediate the way were actadaptively to the important events occuring in our lives. During its emotional development, a child is becoming aware of itself and its possibilities- which the nallows him/her to develop and create itsself-image. Self-image can be described as the way in which we see ourselves, the ways in which we describe our seves and how we describe our inner states. The goal of this master thesisis to describe this self-image development in detail, as well ad to examine the correlation between certain personal (temperament, emotional regulation) and environmental factors (parents’ education llevel, time spent in front of the screens) and a forementioned self-image. On the basis of the data recieved, it can be concluded how children between ages 5 to 7 display high levels of emotional regulation and self-understanding. The willingness of putting an effort has proved to be the most prominent dimension in terms of temperament. Also, the differences between sex es when it comes to evaluating one’s appearance have also be enestablished. Namely, girls show more satisfaction in terms of their own appearance. Furthermore, correlations between said personal and environmental factors have also been noticed.
