Chapter 9
How is Language Possible?
 Theories
 Defining language
 Design Features
 Primates
 Acquisition of Language
 Speech Sounds
 When is language possible?…
 How is language possible?….
Contemporary Theories
 Theoretical linguistics:
 Still speculative
Language- evolved at once
 Language- innate feature in humans
 Children born with universal grammar


Only need to acquire specifics
 Linguistic anthropology:
 Uses all four fields of anthropology
Language too complicated to have developed all at once
 Language probably evolved slowly along with culture
 Children born with ability to learn language


Learning takes place in social situations.

Defining Language
 Hockett’s Design Features of language
 1960s
 Defining what is unique to humans
 Thirteen features

Four are unique to human language.
Design Features of Language
Not Unique to Humans
 Vocal/auditory channel
 Broadcast transmission /
directional reception
 Rapid fading
 Interchangeability
 Total feedback
 Specialization
 Semanticity
 Arbitrariness
 Discreteness.
Unique to Humans:
(according to Hockett)
10.Displacement
11.Productivity
12.Traditional transmission
13.Duality of patterning
/ k + æ + t + s /.
Design Features and the Emergence of
Human Language
 The idea of blending
 Combining calls to establish productivity
 Starting from closed calls (limited, specific)

A+B=A+B


Moving to blended calls (prelanguage)

A + B = AB



danger + food = danger + food
danger + food = dangerous food
breakfast + lunch = brunch
Making duality of patterning possible

Isolation of units for recombining

A + B + C = ABC, CBA, BAC, ACB
Primate Communication
 Experiments:
 Chimpanzees
 Gorillas
 Orangutans
 What this tells us about language
 Duality of patterning is uniquely human
 What it tells us about language origins
 Pre-language abilities of humans and other primates
probably similar.
Acquisition of Language
 Development of linguistic ability is linked to maturation
of cognitive processes
 Sounds as abstract and arbitrary can be used to stand for
objects and ideas
 Chomsky (p.247):

“speaker’s ability to produce & understand instantly new sentences
that are not similar to those previously heard… It seems plain that
language acquisition is based on the child’s discovery of what from a
formal point of view is a deep & abstract theory- a generative
grammar of his/her language”
 Jean Piaget & Lev Vygotsky’s theories

Individual cognition & social needs as driving force for language
Children and Language
 3 days – recognizing parents’ sounds
 3 months – cooing, playing with intonation
 6 months – babbling, playing with sounds
 9 months – beginning signs
 1 year – recognizable spoken words & speak single
words (Holophrastic)
 15 months – naming “explosion”
 2 years – simple sentences, displacement
 Then – negatives, questions, clauses.
Theories about Language in Children
 Innatist theories
 Language hard-wired in brain
 Behaviorist theories
 Stimulus and reward
 Cognitivist theories
 Concepts come first
 The theory theory
 Children observe and build theories

Different languages - different theories?
Complex Grammars
 Cognitive development and experiential maturation
stimulate children to expand their linguistic abilities
 Two important themes:
1.
2.
Development awareness that organization w/in sentences is
significant
Transferring learning from one context to others by processes
of analogy & rule generalization.
WHEN is Language Possible?
 Connected to HOW
 Involves research into brain…
 And vocal tract…
 And origins of culture….
The Human Brain
 Cortex
 The convoluted surface of the
brain
 Two millimeters thick
 Surface area 1.5 square yards
 Contains 100 million neurons
 Oldest part of cortex
 Controls long term memory
 And emotion
 Newer part of cortex
 “Neocortex”
 Controls language
 80% of human brain
 Divided into lobes

Frontal
Temporal
Parietal
Occipital.
Lateralization & Language
• Two cerebral hemispheres
• Connected by corpus callosum
 Left hemisphere

 Right hemisphere

touch
space
music
contexts for language
use.
Language Areas of the Brain
 Broca’s area
 Clarity of speech
 Function words
 Some word order
 Wernicke’s area
 Understanding words
 Producing sentences.
The Human Vocal Tract
 Lowering of the larynx
 Where vocal cords are located
 Lengthening of the pharynx
 More space for tongue
 Increased vowel resonance

Differentiation of vowels: [i] [a] [u]
 Human infants born with high larynx
 Begins to lower at three months
 Reaches adult location by 3-4 years

Except in adult males: further descent at adolescence.
The Fossil Record
 Evidence from basicranium
 Where muscles attach
 More curved = lower larynx
 Australopithecus (1.5 mya) not curved
 Homo habilis (2 mya) no data
 Homo erectus (1.6 mya) some curve
 Early Homo sapiens (400,000 ya) definite curve
 Homo sapiens sapiens (125,000 ya) ditto
 Neanderthal (130,000 ya) no curve.
Origins of Culture
 Associating language with complex tools
 evolution of tool design provides clues

complexity of Upper Paleolithic tools
 requires description (vs imitation)
 Associating language with cultural complexity
 art, music, ritual,
cooperative hunting/childcare.
The Fossil Record
 Australopithecus (1.5 mya) first stone tools
 Homo habilis (2 mya) control of fire
 Homo erectus (1.6 mya) organized hunting?
 Early Homo sapiens (400,000 ya) shelters, burials
 Homo sapiens sapiens (125,000 ya) knitting,
basketweaving
 Neanderthal (130,000 ya) burials, music.
