Final answer:
The term used in psychodynamic theory to describe ideas and feelings not available to awareness is 'unconscious.' This part of the psyche contains repressed urges and desires that influence our behavior, according to Freud.
Step-by-step explanation:
In psychodynamic theory, the term that is descriptive of ideas and feelings that are not available to awareness is unconscious. The unconscious contains thoughts, urges, feelings, and memories outside of our conscious awareness. According to Sigmund Freud, much of our mental activity is unconscious, and this part of our psyche plays a significant role in influencing our behavior. Freud suggested that unacceptable urges and desires are kept in our unconscious through repression. Tools such as dream analysis and free association are used to access the unconscious, revealing insights into our innermost thoughts and feelings.
