The Mind As A Computer
Step 1:
• Encoding
• Take in and store information
Step 2:
• Recoding
• Operate on information, revise its symbolic
structure
Step 3:
• Decoding
• Decipher meaning, compare new information
with previously stored information
Step 4:
• Output
• Produce a response, usually a behavioral
performance like solving a task or problem
Behaviorist Foundations
Kendler & Kendler (1962)
Reversal and Non-Reversal Learning
First Discrimination
+
Big equals Yes
-
Little equals No
Second Discrimination
+
Reversal
Little equals Yes
-
Little equals No
+
Non-Reversal
Red equals Yes
Green equals No
Atkinson & Shiffrin’s Store Model
The Levels of Processing Approach
Craik & Lockhart
The retention of information is a function of
the depth to which the incoming stimuli has
been analysed by the system.
Example:
A written word
Levels:
 Superficial:
Perceptual
characteristics
(e.g., capital vs. small case)

Middle:
Deep:
Phonemic characteristics;
How does the word sound?
Semantic features or meaning
Differentiation Theory
Gibson & Gibson
Sample feature overlaps:
A, E:
A, K:
A, C:
K, E:
3 features – straight (horizontal),
intersection, redundancy (symmetry)
4 features – straight (diagonal /), straight
(diagonal \), intersection, redundancy
(symmetry), discontinuity (vertical)
1 feature – redundancy (symmetry)
3 features – straight (vertical), intersection,
redundancy (symmetry)

Strategies in Short Term Memory
Rehearsal
• Production deficit
• A failure to produce an already existing strategy
• Control deficit
• An inability to skillfully use a strategy even
when chosen
Organization and Elaboration
Evaluation of the Information Processing
Approach
Advantages
• Success in providing detailed specification of how
younger vs. older children perceive, attend,
memorize, and so on
• How do children process information in educational
important domains
Problems
• The fragmentation of cognitive processing
• Explicit account of developmental change
• Limitations of the computer metaphor
• The emphasis on verbal, symbolic reasoning
