imagery in tandem with verbal association forms referential connections
across the two cognitive subsystems. Dual coding theory postulates that
referential connections across the verbal and nonverbal memories are
stronger, more flexible than the associative connections within each separate
system, because they add a level of meaning. (one to many)
structure: A within-system network
of links and references. The
functional connections of logogens to each other (in the verbal subsystem) or
of imagens to each other (in the nonverbal subsystem).
|Imagens: Representations from which mental images
are generated. Imagens correspond to
natural objects, holistic parts of objects, and natural groupings of objects.
|Logogens: A hypothetical verbal representation that
registers perceptual word information and makes a word response available
when enough relevant information has accumulated.
availability: The probability that
cues to one subsystem will be able to make associations to memories in the
other subsystem, or that logogens will activate imagens and vise versa. The capacity for stimuli to simultaneously
activate memories in both subsystems is a function of the availability of
connection: A between-system
structural connection or “access route”
that permits activation of memory in one system to trigger activity in
the other representational system. An
example of a simple referential connection is the tie between the image of an
object and its name.
