there was no widely recognized psychological or psychiatric concept known as the "stage of exploration personal world." It's possible that new research or theories have emerged since then, but I don't have access to real-time information.
It's crucial to note that psychological and psychiatric fields are constantly evolving, and new theories and studies are published regularly. If this is a recent development, I recommend looking for up-to-date scholarly articles, books, or reputable sources in the fields of psychology and psychiatry to explore this concept further.
