Encyclopedic Memory
Encyclopedic memory contains the details of knowledge —
encoded in abstract representations whose form we can only guess

but which we picture as consisting of hierarchies of chunks and
concepts, schemata, scripts, relational and associative nets, and so
on. Many researchers subscribe to the opinion that encyclopedic
memory is where language-free concepts are stored. As for other
memories, location of encyclopedic memory is likely spread through-
out the cortex, with separate areas specializing in particular
functions.
Priming Memory
Priming memory is a nonconscious memory, which identifies and
recognizes, conceptually or perceptually, words and mental objects
as cues. When a valid cue is recognized, it triggers a larger, associ-
ated “chunk” that can be quite extensive and complex and can serve
as a pointer for long-term memory retrieval. “Priming is a type of
implicit memory; it does not involve explicit or conscious recollec-
tion of any previous experience. It has affinities to both procedural
and semantic memory” (Tulving & Schacter 1990, p. 301).
Conceptual priming occurs when planning a complex project and
discovering resource contentions between critical tasks. We then
automatically recall how we handled similar situations in the past.
We associate the new situation with the previous ones and remem-
ber the concepts for how to deal with it. Perceptual priming occurs
when, for example, we drive and see brake lights go on in the car
ahead, and automatically start applying the brakes in our own car.
Our priming memory is full of associative links, which point to
knowledge stored in semantic and other memories. For performance
of expertise and for use of knowledge in decision situations and the
like, priming memory is of utmost importance. From this point of
view, priming memory is the major repository of context-dependent
cues and hence contributes heavily to our capability to perform and
exercise our expertise as part of our daily work, particularly if we
are “practical knowledge workers” — which most of us are. We
compile and automate the knowledge that we are experts in, and the
automated scripts and schemata may subsequently be stored as
strings of cues in our priming memory.
