Language consists of a system of symbols
and rules for combining these symbols in ways that can generate an infinite number of possible messages and meanings
Psycholinguistics the scientific study of the psychological
aspects of language, such as how people understand, produce, and acquire language

Adaptive Functions of Language Over the course of evolution, humans
adopted a more socially oriented lifestyle Emergence of new SURVIVAL problems:
The need to create divisions of labor and cooperative social systems
To develop social customs To communicate thoughts To pass on knowledge and wisdom

Properties of LanguageSymbols
The use of sounds, written characters, or some other system of symbols (e.g., hand signs) to represent objects, events, ideas, feelings, and actions

Properties of LanguageStructure
Grammar – set of rules that dictate how symbols can be combined to create meaningful units of communication
Syntax – rules that govern the order of words

Properties of LanguageMeaning
Semantics - the meaning of words and sentences
![Page 7: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/7.jpg)
Properties of LanguageGenerativity
the symbols of language can be combined to generate an infinite number of messages that have meaning
Displacement refers to the fact that language allows us to
communicate about events and objects that are not physically present

Structure of Language
Surface structure consists of the symbols that are used and their order
Deep structure refers to the underlying meaning of the combined
symbols
Consider these sentences: Sam ate the cake. The cake was eaten by Sam. Eaten by Sam the cake was.

Understanding and Producing LanguageBottom-Up Processing
Individual elements of a stimulus are analyzed and then combined to form a unified perception
Top-Down Processing Sensory information is interpreted
in light of existing knowledge, concepts, ideas, and expectations

Acquiring a First Language It represents the joint influences of
biology (nature) and environment (nurture).
Many language experts believe that humans are born linguists, inheriting a biological readiness to recognize and eventually produce the sounds and structure of whatever language they are exposed to (Chomsky, 1965; Pinker, 2000).
![Page 14: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/14.jpg)
Acquiring a First Language
Biological Foundation Human children begin to master
language early in life without any formal instruction
Languages throughout the world that developed independently seem to have common underlying structural characteristics
Recognition and distinction of phonemes
![Page 15: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/15.jpg)
Acquiring a First LanguageLanguage acquisition device
(LAD) an innate biological mechanism that
contains the general grammatical rules common to all languages (Chomsky , 1987)
Universal grammar becomes calibrated to the grammar and syntax of one’s native tongue
![Page 16: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/16.jpg)
Acquiring a First Language
Social Learning Processes Child-directed speech, parentese or baby
talk Parents are more concerned with deep
structure
Language Acquisition Support System (LASS) represent factors in the social
environment that facilitate the learning of a language (Jerome Bruner ;1983)

Development and Sensitive Periods
Reflexive Crying at Birth
Cooing(1-4 months)
Babbling(4-11 months)
One-Word Utterances (12-24 months)
Telegraphic Speech (2-3 year old)
Complex Speech (5 year old)

Nature vs Nurture Genie (the Feral Child)
Subjected to a near-total isolation by her parents for the first 13 years of her life (1970)
Genie's case presented researchers with a unique opportunity. If given an enriched learning environment, could she overcome her deprived childhood and learn language even though she had missed the sensitive period?

NATURE NURTURENoam Chomsky Eric Lenneberg
the acquisition of language could not be fully explained by learning alone.
the ability to acquire language is subject to what are known as sensitive periods
Language Acquisition Device (LAD) - an innate ability to understand the principles of language
Sensitive Period - limited span of time during which an organism is sensitive to external stimuli and capable of acquiring certain skills
Once exposed to language, the LAD allows children to learn the language at a remarkable pace.
The sensitive period for language acquisition lasts until around age 12. After the onset of puberty, he argued, the organization of the brain becomes set and no longer able to learn and utilize language in a fully functional manner.

Bilingualism the use of two
languages in daily life
It is said that a second language would be learned best and spoken most fluently when acquired early in life
![Page 24: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/24.jpg)
Bilingualism and Cognitive Abilities
The Journal of Neuroscience (Jan. 09,2013)
A study of Brian T. Gold, PhD, and colleagues at the University of Kentucky College of Medicine utilizing fMRI
Seniors who have spoken two languages since childhood are faster than single-language speakers at switching from one task to another
Cognitive flexibility – the ability to adapt to unfamiliar or unexpected circumstances
![Page 25: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/25.jpg)
The Bilingual Brain A UCSD study tried to find out how the brain
works in the learning of a second language. In general, they found that in the less proficient language, the brain recruits many more areas than in processing the dominant language
![Page 26: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/26.jpg)
Thinking
The internal language of the mind
refers to any mental or intellectual activity involving an individual's subjective consciousness
![Page 27: Language and Thinking](https://reader033.vdocuments.us/reader033/viewer/2022061216/54b2894b4a795997688b4618/html5/thumbnails/27.jpg)
Modes of Thinking Propositional Thought
it expresses a statement, such as “I’m hungry” , “ I didn’t eat breakfast” or “It’s almost time for lunch.”
Imaginal Thought consists of images that we can see, hear, or feel in our
mind
Motoric Thought relates to mental representations of motor
movements, such as throwing an object
All three modes of thinking enter into our abilities to reason, solve problems, and engage in many forms of intelligent behavior.

Concepts and PropositionPropositions
statements that express ideasConcepts
basic units of semantic memory—mental categories into which we place objects, activities, abstractions and events that have essential features in common
Prototypes the most typical and familiar members of
a category or class

Reasoning
(1) You are the bus driver. At your first stop, you pick up 29 people. On your second stop, 18 of those 29 people get off, and at the same time 10 new passengers arrive. At your next stop, 3 of those 10 passengers get off, and 13 new passengers come on. On your fourth stop 4 of the remaining 10 passengers get off, 6 of those new 13 passengers get off as well, then 17 new passengers get on. What is the color of the bus driver's eyes?

Uncertainty, Heuristics & Decision Making
Few decisions in everyday life can be made with the absolute certainty that comes from applying some mathematical formula or other algorithm
Typically, the best we can hope for is a decision that has a high probability of a positive outcome

The Nature of Expertise
Expert Schema and MemoryExperts have developed many schemas to guide problem solving in their field, and just as critically, they are much better than novices at recognizing when each schema should be applied. Applying the correct mental blueprint provides a proven route to solving a problem quickly and effectively.

Language and Thinking
Language influences what people think and how effectively they think. Expansion of vocabulary allows people to encode and process information in more sophisticated ways.
