Document Summary
Child rt > adolescent rt > adult rt. Complexity of task led bigger differences between the groups. Ee is physically identical, ee is name identical but physically different. Rt is a + b + c + n. Rt is a + b + x + c . You can also use slope to isolate a component. Specific #s in set, ex: 3, 6, 1, 9. Q: is the systematic decrease of rts during childhood primarily attributable to a single mechanism> Method: measure component speed from 2 very different tasks: name retrieval paradigm (modified) and mental rotation (standard) Name retrieval is constant in the verbal domain. Results: name retrieval duration goes from about 150 ms when 8, to 20 ms when 20. Ms per degree of rotation goes from 5 at age 8 to about 1 at age 20. Conclusion: most basic processing components are maturing at the same rate.
