Final answer:
In psychotherapy, as a client becomes more fully functioning, we would expect the correlation between their real and ideal selves to increase.
Step-by-step explanation:
In the context of psychotherapy, as a client becomes more fully functioning during the course of several sessions, we would expect the correlation between their real and ideal selves to increase. This means that their perception of themselves and their goals align more closely over time.
For example, at the beginning of therapy, a client may have a large discrepancy between their real self (how they see themselves) and their ideal self (how they want to be). However, as therapy progresses and they gain self-awareness and work towards personal growth, the gap between the two selves tends to narrow.
Therefore, the correct answer to this question is c. Increase.
