In her article “Skriveøvelse: Tenk på i går" [English: "Writing Exercise: Think about yesterday"], Ylva Østby Berger presents new insights on the interrelation of memory and creative writing — apparently, remembering sparks an increase in creativity. If you activate constructive episodic simulation (Daniel Schacter), that is, consciously constructing memories, before you start a writing assignment, then creativity increases for certain aspects of what is written afterwards.
