Final answer:
Cheri's nausea upon smelling oatmeal, without consciously remembering past sickness associated with it, is due to implicit memory, demonstrating how classical conditioning affects our behavior and physical responses without conscious recall.
Step-by-step explanation:
Cheri's experience with oatmeal causing a classically conditioned feeling of nausea, despite not remembering the specific events from her childhood, is an example of a implicit memory. Implicit memory is a type of memory that influences thoughts and behaviors without any conscious awareness of these previous experiences.
The nausea that Cheri experiences when smelling oatmeal is an emotional response that demonstrates how classical conditioning affects implicit memory, showing that it's not necessary to consciously recall an event for it to influence our behavior and physical responses. It is a type of memory that is associated with emotional responses or learned behaviors. In Cheri's case, her conditioned reaction to oatmeal is an example of implicit emotional conditioning.
