Revision of one's knowledge and understanding of a topic in response to new information about the topic.
A state of quite in which a person focuses on the present moment and, while experiencing it, his or her cognitive, emotional, and physiological conditions.
Basic Cognitive Processes
Key Ideas
A Model of the Human Information Processing System
Environmental Input
Sensory Register
Holds raw sensory data for a very brief period
(2-3 seconds or less)
Working Memory (WM)
Allows active processing of information; has short duration (less than a minute) and limited capacity
Reasoning

Take-Home Messages
Cognitive science
Input from the environment provides raw material that is later processed.
Human memory has several mechanisms
Attention is needed for getting information into the system
Moving information from WM (working memory) to LTM (long term memory) requires many different processes
Control of information - processing abilities develops gradually over the lifespan
Sensation, then perception
Sensory register, working memory, and long term memory
Rehearsal, organization, elaboration
The Central executive
Sensation & Perception
Perception
Sensation
Interpreting those stimuli
Developmental change
Sensory and perceptual capabilities improved significantly during infancy
Vision, depth perception
Newborns can sense and discriminate
Sights, sounds, taste and smells
Preferred new and interesting stimuli
Preference for social stimuli
Faces, mother's voice, people walking
Nature and nurture both play a role
Attention
Involves active focusing on information
Attention
Developmental change
Distractibility decreases
Sustained attention increases
Attention becomes increasingly purposeful
Affected by stimulus characteristics
People vs. inanimate objects
Develops in Social context
Working Memory & the Central Executive
Central executive
Developmental change
Working memory
Overseas flow I'm information throughout the system
Processing speed increases
Capacity of WM increases
Central executive takes control
Automatization
->
Long Term Memory
Stores accumulated knowledge and skills; has long duration and unlimited capacity
Long-Term Memory (LTM)
Developmental change
Knowledge Bass
Procedures (how to ride a bike)
Both Universal and culturally specific
Begins before birth
Becomes more conscious by preschool
Amount stored knowledge increases dramatically
Knowledge becomes more integrated
Schemas and Scripps
Autobiographical self develops
Sounds, tastes
Developmental change
increased use of sybols
sensorimotor vs. symbolic thought (Piaget)
Increased logical thinking
gestures before verbal representations
some present in infancy (cause-effect)
inferences by preschool
influenced by personal biases even in adolescence
a way for children to experiment with cognitive ideas
may foreshadow emergence of more sophisticated skill
Provide a variety of sensory experiences
help children pay attention to things that are important
Relate new information to existing knowledge base
Remember that children can only think about small amount of information at my any one time
consider both verbal and nonverbal behaviors
provide opportunities for ongoing practice, conversation about experiences, and more formal assessment
Learning disability
Likely to have biological bias; often genetic
Special Educational Services are required
Significant defect in one or more, different processes
Example: attention deficit hyperactivity disorder
Weakness in central executive is likely
Easily distracted, Daydream, trouble listening and following directions, give up easily
Excessive energy
Impulsivity
Blurred answers, interrupt, makes careless mistakes, act out without thinking through the consequences
Fidgety, move around, talk excessively, difficulty working or playing quietly
Examines children's work for clues about specific processing difficulties
Help children keep their attention on the tasks at hand
Teach social skills
Provide extra scaffolding for studying, doing homework, completing other learning tasks
Teach learning strategies and strategies for controlling hyperactivity and impulsivity
Arrange class schedule carefully
Development of Metacognition & Cognitive Strategies
Machination
Intentional use of cognitive processes to improve learning and memory
Cognitive strategy
Mental process used to regulate thinking, acquire or manipulate information
Example: learning strategy
Rehearsal
Organization
Elaboration
Repeating over and over; repetition
Identifying relations among pieces of information
Categorization
Using prior knowledge to embellish new information
Appear by 12 months
Become increasingly mental
Applying rules (e.g., balance task)
Largely Behavioral (pull cloth to reach string attached to toy)
Children gradually replace simple cognitive strategies with more advanced and effective ones
With time in practice, children become more Adept at applying strategies efficiently, flexibly, and successfully
Conscious appreciation of thought process
Understanding of the limits of human memory
Knowledge of the relative effectiveness of various learning strategies
Developmental
Preschoolers
Aware existence of thought
Limited awareness of own thought processes
Language precedes full understanding
No, remember, forget appear in preschoolers
Overly optimistic about memory
Beneficial cognitive development
elementary-school children
Better able to reflect on our own thought processes
Increasingly aware of nature of their thinking and learning
Increase knowledge about and use of effective strategies
adolescents
more aware, but may still be metacognitively naïve
Directing and controlling one's own cognitive process to learn successfully
Setting goals for learning activity
Planning study time
Monitoring progress towards goals
Evaluating the final knowledge gained
Self-regulated learning virtually nonexistent in grade-School students
Many secondary students will have difficulty self-regulating learning
Active mental engagement seems to be universally valuable for academic achievement
Cultures different strategies that used to learn and remember
Engage children in discussions about thinking and the mind
Except and encourage increasingly in-depth learning overtime
Provide opportunities for children to evaluate their learning; help them develop mechanisms for doing so effectively
Strategic and self-regulated learning
Personal Theory Construction
Theory theory
researchers' theory about how children
belief that children construct integrated, complex explanations of the world
Example: Children's theories of the physical world
infants know that objects'
are substantive entities w/ definite boundaries
fall unless something holds them up
move in a continuous manner across space
Early conceptions provide foundation for development of more elaborate theory
knowledge may be biologically preprogrammed (nativism)
misconceptions interfere w/ learning new concepts
Encourage an answer an answer why and how questions
When teaching something new, determine what children already know, believe
When children have a misconception, work actively to help them acquire more accurate understandings
Ask challenging questions
Present phenomena that children cannot explain within their existing perspectives
Discuss pros and cons of various explanations of The observed phenomenon
Cognitive processing colon children receive, think about, modify, and remember information
Basic processes include sensation, perception, attention, memory, metacognition
Children gradually construct integrated belief systems (theories), but they are not always accurate
Interdisciplinary perspective on how information is represented and processed
Joint attention, social referencing
Environmental Input
Environmental Input
Detecting stimuli in the environment
Environmental Input
Environmental Input
Enables people to think actively about and process small amounts of information
In-Depth Processing
(e.g. rehearsal, organization, elaboration)
Often involves making connections between new information & existing knowledge
<-
Novelty vs. familiarity
Central Executive
Regulates information flow into working memory and long-term memory
Unlimited capacity
