Final answer:
Humanistic Therapy seeks to help individuals cultivate an optimistic view of themselves and the world, focusing on their potential for personal growth.
Step-by-step explanation:
The school of therapy that primarily aims to cultivate an optimistic perception of oneself and the world is Humanistic Therapy. Humanistic therapy is a psychological approach that emphasizes each individual's potential for growth and the inherent goodness of humans. It diverges from the more deterministic perspectives of psychoanalytic and behavioral schools. One of the primary goals of humanistic therapy, particularly within the framework developed by Carl Rogers, is to help clients achieve a better understanding of themselves, with an optimistic framework for their ability to grow and improve their own lives. Rogers's client-centered therapy employs techniques that foster an environment of empathy, genuineness, and unconditional positive regard, empowering clients to navigate their own path to self-improvement.
