PSYCH 2410 Lecture Notes - Frontal Lobe, Motor Goal, Task Analysis
Document Summary
Research shows that failure on a-not-b task is not so straight forward . Task difficulty: delay (diamond, 1985, fragility of motor plan (diamond, 1985, reaching/pointing vs. Looking: often self-correct, reach to wrong side, but look to correct side. Computer analogy: hardware: memory, processing speed, software: knowledge, strategies. View child as a problem-solver: pulling string to get toy, learn to open fridge to get milk, task analysis, goal > obstacle > strategy, planning, lack of inhibition, distractibility, young kids are overoptimistic. In infants (when solving the pull-cloth-to-get-toy problem: at 10 months requires surface similarity , by 13 months can generalize knowledge even to superficially different problems. In children (when comparing two objects: 6 years cite superficial similarities, 9 years cite deeper relationships. Basic processes (hardware: encoding, children are worse at encoding than adults. Don"t always encode all relevant information: kids getting finger pricked during check-up don"t remember what else happened during check-up, speed of processing, controversy over why it improves.
