Imagination

A related line of enquiry is to determine not only whether the hippocampus is active during future simulation but whether it makes a critical and necessary contribution. While it has been long established that a functioning hippocampus is necessary for the retrieval of detailed autobiographical memories (for a review, see Moscovitch et al., 2005), ... See more

a particularly vivid form of future thinking: the imaginative construction or simulation of scenarios that might occur in one’s future. We hypothesized that the flexible use of episodic details from memory during imaginative simulations of the future can help to understand constructive aspects of memory, such as its susceptibility to distortion (se...

The brain evaluates the images it is processing against a “reality threshold.” If the signal passes the threshold, the brain thinks it’s real; if it doesn’t, the brain thinks it’s imagined.

It took me a while, but I eventually figured out what he meant. Sometimes the task of rebuilding—of accepting what has been broken and making things anew—is so daunting that it can almost feel easier to believe it can’t be done.

But it can.

Particularly relevant to the idea of episodic simulation is the process of forming “implementation intentions” (Gollwitzer, 1999) which involve imagining and rehearsing a plan with reference to the specific future context in which it will be executed. Research has shown that creating implementation intentions significantly increases the likelihood ... See more

This suggests that the linear relationship between plausibility and hippocampal activity observed in the Weiler et al. study may not hold for the entire spectrum of plausibility. Instead, extremely implausible events may be associated with decreased hippocampal activity (relative to less implausible events), as observed in the current study where h... See more
