The kidnapping of W. S. Gilbert

Gilbert's probable screen memory of having been kidnapped, along with his persistent preoccupations with babyhood, remembering and forgetting, stress the intensity of his struggle against remembering the painful experiences from his childhood. His creative efforts function as an obsessional defense; they divert his attention from the experiences themselves to a fascination with the process of remembering and forgetting, while the painful affects are reversed into playful, good-natured humor. The results are some of his most treasured anecdotes. Watson (1918) quotes Gilbert's story of the amateur burglar who badly bungled an attempted robbery and ended up being arrested and jailed under the most humiliating circumstances. For years afterward, every time he though of the incident, he felt wretchedly uncomfortable, and he tried vainly to drive the occurrence from his mind. The story concludes with a statement which, remarks Watson, only Gilbert could have written: "Gradually one detail after another slipped from my recollection, and one lovely morning last May I found to my intense delight that I had absolutely forgotten all about it" (p. 94).     

Neural and behavioral effects of interference resolution in depression and rumination

Individuals diagnosed with major depressive disorder (MDD) often ruminate about their depression and their life situations, impairing their concentration and performance on daily tasks. We examined whether rumination might be due to a deficit in the ability to expel negative information from short-term memory (STM), and fMRI was used to examine the neural structures involved in this ability. MDD and healthy control (HC) participants were tested using a directed-forgetting procedure in a short-term item recognition task. As predicted, MDD participants had more difficulty than did HCs in expelling negative, but not positive, words from STM. Overall, the neural networks involved in directed forgetting were similar for both groups, but the MDDs exhibited more spatial variability in activation in the left inferior frontal gyrus (a region critical for inhibiting irrelevant information), which may contribute to their relative inability to inhibit negative information.
