cognitive memory and its utilization in problem solving. The model comprises of
three distinct units namely
input for
decision making
STM
LTM
For storage
in the LTM
input from sensory
receptors/memory
Fig. 2.4: Tveter’s Model showing direct entry to the LTM.
Episodic memory stores information about happened events and their
relationship. The semantic memory, on the other hand, represents knowledge
and does not change frequently. The procedural memory saves procedures for
execution of a task [33]. A schematic architecture of Tulving’s model is
presented in fig. 2.5.
The episodic memory in fig. 2.5 receives an information “the sky is cloudy”
and saves it for providing the necessary information to the semantic memory.
The semantic memory stores knowledge in an antecedent-consequent form.
The nodes in the graph denote information and the arcs denote the causal
relationship. Thus the graph represents two rules: Rule 1 and Rule 2, given
below.
Rule 1: If the sky is cloudy
Then it will rain.
Rule 2: If it rains
Then the roads will be flooded.
