Regression
What it means
Reverting to an earlier developmental stage of functioning under stress.
Worked example
A hospitalised child resumes bedwetting or thumb-sucking.
In the exam
A previously toilet-trained 5-year-old, admitted to hospital, starts wetting the bed and demanding a bottle.
What settles it
Regression returns to earlier developmental behaviour. It is a response to current stress, not an attribution (projection) or a flip (reaction formation).
Classically confused with
Acting out
