ELEMENTS OF REPRESSIONELEMENTS OF REPRESSION1. “Repression is the selective forgetting of
materials that cause the individual pain”2. “Repression is not under voluntary
control”3. “Repressed material is not lost but
instead is stored in the unconscious and can be returned to consciousness if the anxiety that is associated with the memory is removed”
(Freud [1915] 1957)

DIFFERENTIAL RECALL:PLEASANT vs. UNPLEASANT EXPERIENCES
DIFFERENTIAL RECALL:PLEASANT vs. UNPLEASANT EXPERIENCES
Early claim: unpleasant events are less likely to be recalled; therefore, they are being repressed
(Jerslid, 1931; Meltzer, 1931; Stagner, 1931)
Intensity of affect
Alternative explanation: Reduced recall of unpleasant experiences is due to a decline in the affective intensity over time associated with the experience, rather than to repression.

DIARY STUDYDIARY STUDY
Measured differential recall and changes in affect for pleasant and unpleasant experiences.
Affective intensity of unpleasant experiences had greater declines than pleasant experiences, and as a consequence, unpleasant experiences were less likely to be recalled.
Why the decline in intensity of unpleasant experiences?

TWO EXPLANATIONSTWO EXPLANATIONS
The experience may not have been as bad as the subject thought at the time of the experience, or it did not result in the severe consequences that were expected.
Since people think more about intense experiences than neutral ones, and repeated exposure results in more positive attitudes toward the experience, attention given to negative experiences results in their becoming less unpleasant and less intense.

Claim: Repression follows stress, but repressed material can be returned to consciousness with the removal of stress.
(e.g., Zeller, 1950, 1951; Merrill, 1954)
Alternative explanation: Decreased recall following stress could be due to interference rather than repression.

Reply from Anderson and LevyReply from Anderson and Levy Evaluation of Freudian theory no our
goal – but Freud did write about repression in terms that sometimes allow for active intentional process.
After only 1 minute of active suppression, subjects were up to 10% worse at recalling these memories
