PSYC 101 Lecture Notes - Lecture 13: Working Memory Training, Number Theory, Mental Rotation
Document Summary
One of first indications of symbolic representation is drawing pictures: this is a common symbolic activity for children, children"s artistic ideas often outstrip their motor and planning capability, most common drawings children make are humans/stick figures. Stick figure drawing is a good predictor of intelligence: early drawings do not represent what is being drawn, but they are representative to the child who drew it. Ex) scribble = sailboat: children make more complex drawings as they get older. Case study: autistic child nadia"s drawing skill worsened as she aged drawings are not meant to resemble object, they are meant to represent it. Symbols come in many forms, and they often simplify reality which allows their units to be manipulated in cognition. Ancient symbol system abacus one of first used symbols: found in roman times, china, russia, babylonia, etc. (but may have arouse independently of one another) All cultures" systems have a specific structure with vertical columns and rows of beads.
