Steps in Information Processing
Overseen by the executive function
* Attention
* Discrimination
* Organization
* Memory
Attention
- Awareness of a learning situation and active cognitive processing
- Orientation - directing focus to the stimulus
- Children are especially motivated by moving or changing objects
- Bright colors are also motivating
- Reaction - amount of time required for an individual to respond to a stimulus
Discrimination
- The ability to identify relevant vs. non-relevant information
- Requires working memory (WM): involves the simultaneous storage and processing of information
Organization
The organization of information for future retrieval
Two kinds of organizational strategies:
* Mediational strategies: a symbol forms a link to some information (e.g., an image may facilitate recall of an event)
* Associative strategies: one symbol is commonly linked with another (e.g., cat/dog, boy/girl)
Short Term Memory
Storage for a small amount of information to be retrieved soon
* Recalling items on a shopping list
* Recalling a phone number
Long Term Memory
- Information that has been rehearsed and organized
Explicit Memory
- Facts and events
- Meaning and concepts
- Important names, dates, etc.
Implicit Memory
- Consists of knowing how to do something, such as putting words together or asking for something
(recall memory)
Transfer or Generalization
The ability to apply previously learned material to similar but novel problems
* When the two are very similar, generalization is called near transfer
* When very dissimilar, generalization is called far transfer
Top Down Processing
- Conceptually driven or affected by expectations about incoming information
(e.g., the cat caught a …)
Bottom Up Processing
- Data-driven; analysis occurs at the levels of sound/syllable discrimination and proceeds upward to recognition and comprehension
(e.g., the cat caught a /b/ …)
Early Cognitive Development
- Humans actively contribute to their own cognitive growth by observing, exploring, experimenting, and seeking information
Sensation
- Reception of sensory information
Perception
- Use of sensory information and previous knowledge to make sense of incoming stimuli
Motor Control
- Muscle movement and the sensory feedback that informs the brain of the extent of that movement
(e.g., movement initiated - baby laughs and lifts arms to be picked up)
Cognition
Mental abilities involved in:
* Comprehension of information
* Langauge acquisition
* Executive function
* Use of knowledge
Early Cognitive Development: Perception
- Babies perceive blurry faces at birth and learn to direct their attention at faces quickly
- 2 months - prefer a “typical face”
- 3 months - perceive facial differences
- Between 4 and 6 months - respond more positively to a smile
- Between 5 and 8 months - begin to perceive their own face
Early Cognitive Development: Motor Control
- Fetus
- Discernible movement begins at seven weeks
- Hand to face contact and body rotation are seen at 10 weeks
- Rhythmic such-swallow pattern established at 6 months
- Newborn
- Movements consist of twitches, jerks, and random movements
- Involuntary motor patterns called reflexes
- 2 months
- Oral muscle control to stop and start movement
- Tactile stimulation is still needed
Early Development: Cognition
- Both biology and experience contribute to determining cognitive development and enabling language
- When a child hears speech sounds over and over, neurons in the auditory system stimulate “connections” in the child’s auditory cortex
Speech Development
- “Cooing” and “Gooing” - noncrying vowel-like sounds
- Babbling: consonant + vowel (CV) combinations
- Reduplicated Babbling: CV - CV repetitions
Consonant repertoire: /p/, /b/, /t/, /d/, /g/, /k/, nasals, and the approximant /j/ - Echolalia speech, or echolalia: immediate imitation of another speaker
Variegated Babbling: adjacent and successive syllables are not identical; sound sequences may also include VCV and CVC structures (bada)
Jargon: a pattern consisting of long strings of unintelligible sounds with adultlike prosody and intonation
Emergence of Early Speech Patterns
- Phonetically consistent forms are consistent prosodic and speech sound patterns (e.g., ‘puda’ - family cat or dog) created by a child
- May not be an imitation of the adult form but an indication of sound meaning relationship
Information Processing & Language Development
- Attention
- Processing Speed
- Memory
- Representational Competence
Attention
- The ability of an infant to focus on something while their mother discusses or manipulates it is important for learning and may be a precursor of focusing on a conversational topic
Joint Attention
- When one person purposefully coordinates their focus of attention with that of another person
- Involves two people paying attention to the same thing, intentionally and for social reasons
