Question

preconscious memories are thought to: involve automatic cognitive processing information. stem from the need to repress traumatic memories or taboo desires reside below the level of awareness until they are needed by consciousness. detect changes in biological functioning and regulate them without conscious awareness.

Explanation:

Preconscious memories are memories that are not currently in awareness but can be easily retrieved when needed. They are not repressed (as in the case of repressed memories from trauma which are in the unconscious in Freud's theory), they don't involve automatic cognitive processing (which is more related to implicit memory in some cognitive processes), and detecting biological function changes without awareness is more related to some autonomic nervous system - related processes. According to Freud's topographical model of the mind, preconscious memories reside below the level of awareness until they are needed by consciousness.

Answer:

Reside below the level of awareness until they are needed by consciousness.
