Phobias manifest in different ways in our life. Some people have fear for heights, spiders, water, and others. Phobias are types of learning that are classified under classical conditioning. The main cause of phobias is not clearly understood. The development of phobias however follows systematic steps in a way that mimic classical and operant conditioning. Specific phobias are however developed by genetics and childhood trauma. However, classical conditioning and operant conditioning helps us to map the process of development of phobias.
