Information Processing Model

Information Processing• Sensory Memory

– fraction of a second– iconic and echoic

• Short-term Memory– duration: 2-30 seconds– capacity: 7+2 pieces of information– maintenance rehearsal– chunking– interference

Information Processing

• Long-term Memory– relatively permanent storage of information– encoding– elaborative rehearsal– recognition memory– recall memory

Elaborative Rehearsal

• Implicit and Explicit Memory– In LTM

• Implicit memory– Unintentional and automatic– Stable through lifespan

• Explicit memory– Deliberate and effortful– Recognition and recall tests– Increases until old age

Development of Memory: Infancy• Recognition memory: foot-kick paradigm

• Recall memory

• Child Learning and Memory – Why memory improves

–Basic capacities• Faster, more efficient processing• Storage capacity stable• Automaticity

–Strategies improve• Rehearsal by age 7• Organization by age 10• Elaboration later

• Metamemory–Knowledge of memory–Memory monitoring and regulation –Evidence by age 2

• Unrealistic estimations• Accuracy by age 6

–Linked to improved memory
