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
-
Big equals No
+
Non-Reversal
Red equals Yes
Green equals No

The Levels of Processing Approach
(Craik & Lockhart, 1972)
Fergus Craik
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:
Phonemic characteristics;
How does the word sound?

Deep:
Semantic features or meaning
Attention
Inhibition
• The ability to inhibit impulses and keep goals in
mind
• Contributions of scaffolding
• The Tools of the Mind curriculum
Planning
• Thinking through sequences of action
• Cultural tools that support planning
• Planning in older children
Selectivity and adaptability
• Increases in the ability to selectively attend
• The Dimensional Change Card Sort task
• How do children acquire better attentional
strategies?
The Dimensional Change Card Sort Task
(Zelazo et al., 1995; Zelazo, 2006)
Philip David Zelazo
Attention
Inhibition
• The ability to inhibit impulses and keep goals in
mind
• Contributions of scaffolding
• The Tools of the Mind curriculum
Planning
• Thinking through sequences of action
• Cultural tools that support planning
• Planning in older children
Selectivity and adaptability
• Increases in the ability to selectively attend
• The Dimensional Change Card Sort task
• How do children acquire better attentional
strategies?
• Production Deficiency
• Control Deficiency
• Utilization Deficiency
• Effective Strategy Use
Memory
Recognition and Recall
• Recognition
• Noticing that a stimulus is the same as one
you’ve previously experienced
• Recognition memory in infancy
• Brown and Campione (1972)
• Recall
• Cues are provided as to the original stimulus,
and you have to reproduce that stimulus
• The use of mental strategies
• Rehearsal, organization, categorization
• DeLoache & Todd (1988)
• Changes in mental strategies with age
• Use of rehearsal and organization
• Use of elaboration
Memory for everyday information (episodic memory)
• Memory for familiar events – scripts
• Memory for one-time events – autobiographical
memory
Theory of Mind (metacognition)
Awareness of mental life
• Joint attention
• Beliefs and Desires
• False-belief task
Social referencing
Theory of Mind (metacognition)
School-age child’s theory of mind
• Knowledge of cognitive capacities
• Understanding of cognitive processes and their
impact on performance
• Understanding of sources of knowledge
• 2nd order false belief task
• DeLoache & Todd (1988)
• Changes in mental strategies with age
• Use of rehearsal and organization
• Use of elaboration
• Knowledge of strategies
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
