What is the cognitive definition of memory reconsolidation?

Reconsolidation is the process where reactivating a consolidated memory makes it temporarily malleable, requiring restabilization to persist.

What is required to initiate the process of reconsolidation for a consolidated memory?

The memory must be reactivated using a retrieval cue.

Why did researchers predict that playing a visuospatial game during reconsolidation would reduce intrusive memories?

They hypothesized it would compete for limited working memory resources with visual imagery, disrupting the restabilization of the memory.

Why did the reactivation task include a 10-minute break before playing Tetris?

To provide enough time for the memory reconsolidation processes to be initiated.

What instructions were given to Tetris players to encourage mental rotation and tax visuospatial working memory?

They were asked to focus on upcoming preview blocks and work out in their "mind's eye" where to place them.

How did the instructions distinguish an intrusive memory from deliberate recall in the diary?

Intrusive memories were defined as spontaneous, unbidden visual scenes, excluding memories that were intentionally recalled.
