revising information's symbolic structure into a more effective representation
-
decoding
interpretting information's meaning by comparing and combining it with other information in the system

- permanent knowledge base
- retrieval can be problematic
- information is categorized by contents
-
implications of store model
suggests two broad aspects of the cognitive system increase with age - the basic capacity of its stores; the extent and effectiveness of strategy use
-
connectionist models
- artificial neural network model
- simulate the workings of the most basic information-processing units (neurons and their connections)
- reveal how strengthening of simple connections between neurons promotes development of brain functioning
- consists of thousands of simple processing units organized into layers
-
neo-Piagetian theory
- Robbie Case
- accepts Piaget's stages
- attributes change within each stage, and movement from one stage to the next
-
three factors contribute to cognitive change
- brain development
- practice with schemes and automization
- formation of central conceptual structures
-
central conceptual structures
networks of concepts and relations that permit people to think about a wide range of situations in more advanced ways
-
model of strategy choice
- Robert Siegler
- effort to apply an evolutionary perspective to children's cognition
- some strategies are selected, become more frequent, and "survive"
- some strategies become less frequent and "die off"
- children's mental strategies display variation and selection, yielding adaptive problem-solving techniques
-
effective strategy use
by mid-elementary school, children use strategies consistently and performance improves
-
planning
involves thinking out a sequence of acts ahead of time and allocating attention accordingly to reach a goal
-
cognitive control
the abilities of inhibition, effortfully holding and operating on information in working memorey, and flexibility adjusting attention to changes in task requirements
-
rehearsal
- memory strategy
- repeating information to yourself
-
organization
- memory strategy
- grouping related items
-
taxonomic categories
- memory strategy of older children
- grouping items based on common properties
- ex: clothing, body parts, food etc.
-
control deficiency
- slightly older children sometimes produce strategies, but not consistenly
- they fail to control, or execute strategies effectively
-
production deficiency
- preschoolers rarely engage in attentional strategies
- they fail to produce strategies when they could be helpful
-
utilization deficiency
- young elementary school children execute strategies consistently
- their performance either does not improve or improves less than that of older children
-
elaboration
involves creating a relationship, or shared meaning, between two or more pieces of information that do not belong to the same category
-
how to we retrieve information
- recognition
- recall
- reconstruction
-
recognition
noticing that a stimulus is identical or similar to one previously experienced
-
recall
generating a mental representation of an absent stimulus
-
reconstruction
recoding information while it is in the system or being retrieved
-
fuzzy-trace theory
- when we first encode information, we reconstruct it automatically
- we create a vague, fuzzy version (gist), which preserves essential meaning without details and is especially useful for reasoning
-
semantic memory
- our vast, taxonomically organized and hierarchically structures general knowledge system
- must grow out of the young child's episodic memory
-
episodic memory
- of young child
- memory for many personally experienced events
-
scripts
genderal descriptions of what occurs and when it occurs in a particular situation
-
autobiographical memory
representations of one-time events that are long-lasting because they are imbued with personal meaning
-
infantile amnesia
the inability to remember events that happened to us before age three
-
self-regulation
the process of continually monitoring progress toward a goal, checking outcomes, and redirecting unsuccessful efforts
-
what makes a good reader?
- being able to...
- percieve single letters and letter combinations
- translate them into speech sounds
- recognize visual appearance of common words
- hold chunks of text in working memory while interpreting their meaning
- combine meanings of various parts of a text passage into an understandable whole
- do these tasks automatically
-
whole-language approach
- argued that reading should be taught in a way that parallels natural language learning
- children should be exposed to text in its complete form so they can appreciate the communicative function of it
-
phonics approach
- believing that children should first be coached in phonics
- after mastering this skill, they should get complex reading material
-
skills to be good at math
grasp the concept of ordinality (order relationships between quantities)
-
Asian countries and teaching math
- use of metric system
- consistent structure of number words
- more digits can be held in working memory at once which also increses the speed of thinking
- children learn to use the number 5 as an anchor
- spend more time exploring math concepts and strategies and less to drill and repetition
- high school students score higher in math achievement
-
Hearing what someone has said is an example of:
encoding
-
Why, according to the store model (Atkinson and Shiffrin), do we sometimes have problems with retrieval of information from the long-term memory store?
there is so much input stored there
-
According to the store model (Atkinson and Shiffrin), the first component of the store model is:
sensory register
-
Automatization is an aspect of the:
levels-of-processing model
-
An aspect of information-processing models that may change with age is:
- the "hardware" or absolute size of its processing units
- the "software" or the extent and effectiveness of strategy use
-
Case's non-Piagetian theory accepts Piaget's stages but:
views change within each, as well as movement from one stage to the next, due to increases in information-processing capacity
-
What is the reason for movement form one stage to the next, according to Case?
increases in information processing capacity
-
Connectionism holds that the _____ of the artificial neural networks is responsible for encoding a given task.
input layer

According to Siegler, ______ consider both weith and distance when solving the problem of the balanced scale.
adolescents
-
Which information-processing approach to development comes from an evolutionary perspective of cognitive development?
model of strategy approach
-
Young children that first start using the rehearsal strategy for storing information are typically not very adept at it because of ______ deficiencies.
- production
- control
- utilization
-
The preschool child's minimal use of rehearsal and the young elementary school child's less effective execution of it reveal that:
becoming skilled at this strategy is a gradual process
-
Jacob looks at a collection of paintings. Later he looks at another collection of paintings that has some new ones mixed in. He identifies the ones that he looked at previously. He is retrieving information using the ___________ memory strategy.
recognition
-
Josef tells a long and complex story to Chris. Chris tells the story to Christine the next day and it is a little different. Chris is retrieving information using the _______ memory strategy.
reconstruction
-

- semantic memory
- episodic memory
-

- enable us to predict the future
- help us organize our everyday lives
- help us to interpret what is happening to us
-
Metacognition refers to:
an awareness and understanding of our own cognitive processes
-
An argument for using a whole-language approach when learning/teaching to read is that:
