I’m stuck on a Psychology question and need an explanation.

The purpose of this discussion is for you to demonstrate your understanding of the material. Approach your response as though it is a mini essay with complete sentences, distinct paragraphs, and correct spelling and punctuation. Grammar and spelling matter. Online courses demand the same standard of academic communication and use of grammar as face-to-face courses.

Using a minimum of 300 words, provide a thorough response to the following prompts:

1. Describe the definition of a psychological disorder provided by the American Psychiatric Association (APA), including the four criteria. Why isn’t any single criterion adequate for classifying abnormal behavior? Which of these criteria would apply to those featured in the bipolar video and the OCD video?
2. Review the Symptoms of Schizophrenia section of the chapter and identify the symptoms that are displayed in the Schizophrenia: John Nash video included in this module. Describe the specific symptoms that you see exhibited in the video.
3. Watch the Carson Daly – Anxiety Disorder video. How does Carson explain why he developed an anxiety disorder? How are his explanations similar and/or different to the explanations for anxiety disorders provided in the textbook?

In addition, you are expected to provide a supportive and/or reflective comment to the post of one classmate. In order to receive the maximum possible 10 points, you must accurately and thoroughly answer each part of the discussion prompt using at least 300 words (including the prompt in your response is not included in the word count) and comment on the post of one of your classmates.
