Document Summary
Information processing and the process/mechanisms of change. Three parts of mental system to process. Wm: number of items held in mind while engaging to manipulate. Verbal memory span task: number of items backwards. Central executive: directs flow of information; conscious, reflective. Automatic process: well-learned habits, doesn"t require wm. Basic capacity (working memory capacity impacts ability to learn. Speed: processing is quicker and easier with age. Executive function: set of cognitive operations and strategies necessary for self-initiated behavior in novel situations. Siegler"s model of strategy choice: like evolutionary model; children have a variety of strategies that are selected based on their usefulness and effectiveness, variation vs selection. Overlapping waves pattern: select strategies based on speed and accuracy. Speech-gesture mismatch: hand gestures in explanatory steps in math indicated a gap in explanatory ability child knew more than s/he could explain. Gains in sustained attention for goal-directed behaviors. Attention improves sharply between 6-10 years (asked to tap button during certain sequence)
