Four research paradigms explored links from secrecy to the suppression
and intrusive recurrence of secret thoughts. In Study 1, keeping a wo
rd secret enhanced cognitive accessibility of the word on a Stroop col
or-naming task. Study 2 revealed that secret memory topics were recall
ed earlier than topics about which a lie or the truth was told. Study
3 showed that when participants were keeping secrets, their ratings of
suppression and intrusive thinking of the secret became positively co
rrelated. Study 4 participants rated 50 everyday topics for intrusiven
ess, suppression, and secrecy. Across topics, positive mean within-sub
ject correlations were found among these variables.
