, Two Contrasting Models of Memory
- Represent ways that memory has been
conceptualized.
- Primary memory (James, 1890): Holds
temporary information currently in use.
- Secondary memory (Waugh & Norman, 1965)
Holds information permanently or at least for a
very long time.

of information for very brief periods.

- Recall was higher in the
Averbach-Coriell procedure than in the
Sperling procedure because of lesser
output interference: Subjects had to

- Hypothetical constructs: Concepts that are
not themselves directly measurable or

Sensory Store (Iconic Store)
- The initial repository of much information that

- Iconic store: Discrete visual sensory register
that holds information for very short periods.
