I am building a system map for my thesis. Last semester I made this map to show the dichotomy of the influences of digital technology in a child's cognitive development. Base on my research there was a complex relation between positive and negative. For example, communication skill is the area that show the clear two distinguish influence. Digital technology changed kids to communicate more on social networks than in person. As a consequence, young kids are good at exchanging information. However, the downside is that they are lack of negotiating and building a deeper friendship. 

Even if the map is symmetrical, the category of subjects are not identical side to side. So in the new map, I tagged each categories to indicate what they are representing. Also, I added the stockholder in between to let views know what is the role of stockholders.
