- Mental processess
- sensation
- perception
- concept formation
- reasoning
- decision making
- problem solving
- language
What is Thinking?
- Mental representation and manipulation of information
- mental images
- words
- Concepts
What is Manipulation of Information?
When we solve problems, make decisions, think creatively
Thought & Language - Lev Vygotsky
- Language guides and stimulates thinking
- Thoughts and language are separate systems to start with
- they merge around 3 years old
- begin to produce verbal thought (inner speech)
Thought & Language - Jean Piaget
- Language follows from the ability to think and reflect
- language depends on thought to develop
- thought comes before language
What is language?
- Communicating thoughts and feelings
- uses a system of socially shared but arbitrary symbols
- Written and verbal signals which have rules of grammer
Definition: Language
- symbols that convey meaning
- rules for combining symbols (grammer)
- Infinite variety of messages
- Symbolic
- sounds and written words represent objects, actions, events and ideas
Language is . . .
- symbolic
- semantic
- meaningful
- generative
- structured
The Structure of Language
- Phonemes
- Morphemes
- Pragmatics
- Syntax
- Semantics
Phonemes
Smallest units of sound in a spoken language
Morphemes
Smallest units of meaning in a language
Pragmatics
Patterns of intonation and social roles associated with a language
Syntax
Specifies the rules for arranging and combining words to form phrases and sentences
Sematics
Meaning derived from morphemes, words and sentences
Surface Structure
The order of words in a sentence
Deep Struture
The underlying meaning of the sentence
Why is understanding Speech Complicated
- Letters sound different depending what follows
- Words are not usually separated by silence
- Sounds and verbal cues detected by bottom up processing
- Sounds and cues understood guided top down processing
First Year of Language
- infant vocalisation initially similar across cultures
- usually involves all phenomes
- by 6 months babbling starts to resemble the infants surrounding language
- by 12 months first words are usually spoken, this is similar across cultures
- Uses non verbal behaviour to communicate
Language 2nd Year
- 12-18 months is the one word stage
- Vocabulary expands dramatically in this time
- Starts to use two word “telegraphic” sentences
- over application of past tense rules and irregular verbs
- Sentence expanded with adjectives
Telegraphic Sentences
A concise sentence typically containing five words or less.
Language 3rd Year
- Begin to use auxiliary words eg: adam is going
- Begin to ask questions using “wh” words
- Begin to join clauses to form complex sentences
- Acquire most grammar rules by age 5
Milestones in Language Development
- Birth: Crying
- 2 months: Cooing
- 6-12 Months Babbling
- 12 Months: One word phrases
- 18-24 months - Two Word Phrases
- 24-36 months - Complex Speech
