Theoretical perspective proposing that some knowledge is biologically built-in and available at Birth or soon after.

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

Facilitating Cognitive Processing

Exceptionalities in Information Processing

Working With Children Who Have Information Processing Difficulties

Metacognition and Cognitive Strategies

Learning Strategies

Problem-Solving Strategies

Strategy Development as “Overlapping Waves”

Metacognitive Awareness

Self-Regulated Learning

Cultural Roots of Metacognition

Promoting Metacognitive & Strategic Development

Personal Theory Construction

Facilitating Children’s Theory Construction

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

:

Content (where are cookies)

Knowledge about cognitive processes

Theory--integrated belief system about topic

Memories last longer if used frequently
