Task 4: Information Processing Theory Flashcards
Information-processing theories
a class of theories that focus on the structure of the cognitive system and the mental activities used to deploy attention and memory to solve problems
Task analysis
the research technique of identifying goals, relevant information in the environment, and potential processing strategies for a problem
Means-end analysis
involves repeatedly comparing one’s current state with one’s goal and then taking step to reduce the distance between them (see problem)
Discuss the similarities with Piaget
- Aimed to answer same fundamental question: what develops and how does development occur?
- Try to identify children’s cognitive capabilities at various points in development
- Explain how more advanced understandings grow from more primitive ones
Discuss the differences with Piaget
- Greater emphasis on role of processing limitations, strategies of overcoming limitations, knowledge about specific content
- More precise analysis of change, occurs continuously unlike Piaget’s belief that children progress through qualitatively distinct, broadly applicable stages separated by brief transition periods
Give 2 characteristics of these theories
- specifies precisely the processes involved in children’s thinking
- puts emphasis on thinking as an activity that occurs over time
- > single behaviour may reflect extended sequence of rapid mental operations
Name the 2 central developmental issues
- development of memory
2. development of problem solving
Sensory memory
- Capacity for briefly retaining relatively large amounts of information just encoded
- 5-year-old’s sensory memory as good as an adult’s
Working/short-term memory
- Combines information coming into sensory memory with information stored in long-term memory
- Spatial and verbal information are represented separately in working memory however children under 10 find it difficult to seperate
- Limited in capacity and timespan (varies between tasks, however improves with age and experience)
Long-term memory
- Information accumulated over their lifetime
- retains unlimited amounts of information for an unlimited period of time
- factual, conceptual (e.g. justice, equality), procedural knowledge (e.g. how to tie a shoelace), attitudes (e.g. likes, dislikes), reasoning strategies
Executive functioning/control of cognition
- Prefrontal Cortex- plays important role in cognitive control
- Integrates working + long-term memory to accomplish goals
- quality during early childhood is predictive of important life outcomes i.e. achievements
Basic processes (an explanation of memory development)
- the simplest more frequently used mental activities e.g. associating, recognizing, recalling, generalizing, encoding
- biological (myelination and increased brain region connectivity) lead to processing speed increase
Automatization
change from controlled to automatic as people gain experience
-> Once skills learned to sufficient degree, tough to inhibit
Controlled vs Automatic processes
controlled- require great deal of attention
automatic - require little if any attention
Amount of attention needed on a task is influenced by (x3)
- The type of information that is being processes
- Amount of experience child has had processing that type of material
- Practice reduces amount of attention needed
Encoding
– the process of representing in memory information that draws attention or is considered to be important
- not encoded, not remembered
- shows how memory is “selective”
Rehearsal
repeating information multiple times to memorise (appears around age 6)
Selective attention
intentionally focusing on information that is most relevant to current goal
Retrieval
taking strategies from long-term memory e.g. not being able to think of something immediately therefore going through the alphabet to remember a name
