Place in Cognition
Stickgold et al. (2000) have proposed that Tetris imagery is a separate form of memory, likely related to procedural memory. This is from their research in which they showed that people with anterograde amnesia, unable to form new declarative memories, reported dreaming of falling shapes after playing Tetris during the day, despite not being able to remember playing the game at all.
A study, conducted by Lynn Okagaki and Peter Frensch in 1994, showed that participants who played Tetris for twelve 30-minute sessions (with no previous experience of the game) did much better than the control group in both the paper-pencil test version of spatial skills as well as the computerized version. The conclusions drawn from this experiments were that video games such as Tetris had a positive effect on three areas of spatial skills including mental rotation, spatial perception and spacial visualization in those who played for a prolonged period continuously.
Another 2009 Oxford study suggests that playing Tetris-like video games may help prevent the development of traumatic memories. If the video game treatment is played soon after the traumatic event, the preoccupation with Tetris shapes is enough to prevent the mental recitation of traumatic images, thereby decreasing the accuracy, intensity, and frequency of traumatic reminders. "We suggest it specifically interferes with the way sensory memories are laid down in the period after trauma and thus reduces the number of flashbacks that are experienced afterwards," summarizes Dr. Emily Holmes, who led the study.

“Intuitive cognition of a thing is cognition that enables us to know whether the thing exists or does not exist, in such a way that, if the thing exists, then the intellect immediately judges that it exists and evidently knows that it exists, unless the judgment happens to be impeded through the imperfection of this cognition.”
—William of Occam (c. 12851349)
