Final answer:
Psychologist's professional behaviors are guided by the American Psychological Association (APA) Code of Ethics, which provides a framework for ethical conduct in their practice.
Step-by-step explanation:
The behaviors that psychologists should aspire to in their practice are included within the American Psychological Association (APA) Code of Ethics. This code of ethics acts as a guiding framework for professional conduct and outlines principles and standards that psychologists should strive to uphold, including beneficence, integrity, and respect for individuals' rights and dignity. While the Diagnostic and Statistical Manual of Mental Disorders (DSM) is a critical resource published by the American Psychiatric Association for diagnosing and classifying mental disorders, the APA Code of Ethics is specifically designed to guide ethical practice within psychology.
