Lecture 5 - Information Processing and Social Context Flashcards
Traits of Stage Theory
Qualitative differences between stages
Can only move forward, can’t skip
Must pass certain thresholds to progress
Why did Piaget’s stage theory fail?
There was a lack of thought processes to apply to the principles (only one attribute explored at a time)
Criticisms of Piaget
Superficial changes in design can affect results
Success at younger ages challenges his theory
The experiments may not measure the target cognitive ability
Information Processing Approach
Children fail these tasks because of other cognitive memory limitations (memory, problem-solving, attention, metacognition).
Limitations that can effect children’s problem solving
Encoding (don’t encode appropriate info), computational (don’t have LTM strategies), retrieval (retrieve inappropriate strategy), storage, work-space (working memory restrictions)
Piaget and Inhelder (1951) - Mountains task
The child is given a demonstration of 3 mountains and asked to describe the doll’s point of view. Four year olds always described what they could see whereas 7-8 year olds understood the task.
Brainerd (1983)
The reason younger children were less successful in the mountains task was due to information processing limitations
Vurpillot (1968)
Spot the difference task - 3-5 year olds only examined some and 6-9 year olds looked at all the windows for a difference.
Miller and Seier (1994)
3-4 year olds opened all the boxes to spot the difference while 9-10 year olds focused on appropriate boxes
Roebers et al (2010) - Experiment
Comparing 7-8 year olds with 9-10 year olds on eye tracking test
• Baseline and critical trials
• Recognition test: asked whether they’d seen an image before
• Distractibility test
Roebers et al (2010) - Results
Similar pattern in both age goups
• Looked more overall at task relevant stimuli
Younger children more affected by distractors
Evidence for continuous development
Encoding strategies
Rehearsal, organisation, elaboration
Rehearsal
Mental repetition of information (older children apply strategy more effectively)
Organisation
Grouping information together (10 years and older organise more effectively)
Elaboration
Making associations. Example: 2 words to remember, combine into image or sentence
