I. Overview
A. basic assumptions1. thinking is information processingB. in contrast to Piagetian theory2. precise analysis of change mechanisms
3. self modification
4. automatic vs. effortful processes
1. similaritiesa. emphasis on basic questions2. differencesa. greater emphasis on the role of processing limitations, strategy use, and one’s knowledge base b. greater emphasis on the precise analysis of change
c. greater emphasis on the contrast with adult thinking
II. An Overview of the approach
A. the multistore model1. sensory memoryB. Basic Processesa. defined2. working memoryb. no apparent capacity changes with age
a. memory span3. long term memory1. influencesb. Baddeley’s modela. chunkingb. strategy use
1. verbal and spatial working memorya. Hale et al. (1996): spatial tasks interfered with verbal memory for 8 but not 10 year olds a. recognition vs. recall b. information is stored as units rather than as wholes (e.g., TOT)
1. automatization examplea. automatic vs. controlled processingb. age similarities & differences
2. encoding example1. 5 year olds retain frequency info as well as adults 2. automatization in single-digit addition
a. interference effects increase from small number problems (< 5) for second graders, to small and medium (one addend of 6+) for third graders, to all problem types for older children and adults (LeFevre & colleagues, 1991, 1994) a. age differences in one’s ability to encode important features
1. Kaiser et al. (1986) and predicting paths of a falling ball
a. 70% of children failed, but even college students had problems
2. habituation as encoding
b. some evidence that habituation at 7 months predicts
IQ at age 8
2. young children have had fewer experiences over which to generalize
2. young children are less likely to use them, even when they see their benefit
