This article includes mention of memory compression (and memory function in general):
-----------------------------------------------
Following the pioneering research of the Cambridge psychologist, Sir Frederick Bartlett, in the early part of this century, experts have come to accept that human memory is more reconstructive than previously thought. I.e., memory is not simply a perfect echo of past experience. What seems to be an unadorned replay of past events (often complete with detailed visual imagery) has, in fact, a substantial inferential component which has been shown to be affected by cognitive biases, short-cuts in reasoning strategies, social and contextual processes, and even personality factors.

In recent years, it has been the work of Elizabeth Loftus and her colleagues at the University of Washington that has done the most to cast doubt on this "store everything verbatim" school of memory and to demonstrate the superiority of Bartlett's reconstructive approach.
Since it is clearly impossible, even for the truly astonishing capacities of the human brain, to store every detail of a complex situation, memory must select and compress.
Thus, it registers a few salient features of each episode, along with a label for what Bartlett called a "schema." A schema is a body of knowledge, acquired in the process of acculturation, that summarizes what typically occurs in events of various sorts. Which label is attached to the skeleton event stored in memory is a function of the meaning initially ascribed to the episode. Upon recall, the outline is "filled in" from data contained in the appropriate schema.
Because these inferential and reconstructive processes are largely unconscious, this creative aspect of memory generally escapes our notice. Inasmuch as daily life does include many repetitious, role-governed situations, this way of storing autobiographical memories is economical of our limited capacity to handle information and, most often, leads to a sufficiently accurate account of what transpired. It can, however, also generate egregious errors on occasion, even among highly intelligent and honest individuals.
Potential sources of distorted memories have been discovered at all stages of memory processing. During the initial experience, one's beliefs, wishes, and expectations can direct attention toward certain features of the situation and away from others. This affects how the event is classified from the outset. Because this interpretation influences the label attached to the event in memory, it can bias the selection of the schema that will be engaged to flesh out any later recollection. Significant omissions or insertions can result. Errors can also be introduced at the recall stage when an interrogator's leading questions invite unsound inferences that seem to arise spontaneously from the recaller's own memory. These misinterpretations can then feed back into the system as this modified version of the event re-enters memory to become part of the "recollection" on subsequent attempts.
