For speakers of tone languages, tone/pitch contours are...

linguistic stimuli/words

For speakers of non-tone languages, tones are...

nonlinguistic stimuli/no meaning

The study of our knowledge of the "sound system" in a language:

phonology

The study of the physiology and physics involved in the production and perception of speech sounds:

phonetics

What is used to specify how some words may be formed by combining more than one unit and would allow us to find out what internal structure some complex words may have?

morphology

T/F: Some words can be broken down into smaller units of grammatic information

true

The smallest linguistic units that can bear meanings of grammatical functions

morphemes

Can freely appear by itself; can be an independent word (ex: happy)

free morpheme

Can not be an independent word; must be attached to another morpheme (ex: um, ness, ly)

bound morpheme

A morpheme around which poly-morphemic words are built

roots

Affix at the beginning of a word

prefix

Affix inside of a word

infix

The process of adding an affix:

affixation

May add substantial meaning to a word/linguistic ex: read>>>reader; now its a person not a verb

derivational morphology

Adds grammatical information only ex: hat-s, dish-es

inflectional morphology

The study of our knowledge of phrase and sentence structure

syntax

When a thing is defined in terms of itself or of its type ex: mary loves tom.....tom wonders s1......bill thinks 2s

recursion

How our knowledge of the world affects semantic interpretations

pragmatics

What do we need to know for successful interpretation?

meaning of each linguistic unit; algorithm for combining meanings of each word; have knowledge about the world for proper interpretation

What two different types of meanings may linguistic expressions have?

reference (extension) and sense (intension)

The way entities are picked our or described/ concepts

sense

Using an anaphora/pronoun or using an expression whose interpretation depends on another expression:

anaphoric interpretation

_____ physically and psychologically characterizes all of the speech sounds that appear in the languages of the world

phonetics

What are the three ways to characterized the sound waves used in linguistic communication?

articulatory phonetics, auditory phonetics, and acoustic phonetics

How our vocal organs produce linguistic sounds

articulatory phonetics

How our auditory organs perceive linguistic sounds

auditory phonetics

How machines measure linguistic sound waves

acoustic phonetics

Have only one noise source

sonorants/ resonants

Produced solely by vocal cord vibrations

sonorants/resonants

T/f sonorants/resonants are always voiced unless whispered

true

What is each vowel characterized by in the oral cavity?

which region the highest point of the tongue touches when it is produced

What is the most relaxed position of the tongue placed?

mid/cental

T/f tense vowels require low muscular effort/tension

false; tense vowels require high muscular effort/tension

Lip rounding produces rounded sounds from where in the oral cavity?

high/mid back

Can have 2 different noise sources

obstuents

Produced by obstruction and release of airstream in the vocal tract

obstruents

Where the obstruction of airstream takes place in the oral cavity region

place of articulation

How the obstruction of airstream ismade

stop or fricative

Airstream in the oral tract is stopped, but air passes through the nasal tract

nasal consonants

2 muscular folds located in the pipe shaped bone called the larynx/voicebox

vocal cords

Space between lungs where vocal cords vibrate when the air passes through

glottis

T/f all consonants are voiced

false

Two types of vocal cord vibration:

1. vibration of the vocal cords as a whole
2. vibration of small edges of the vocal cords

The rate of vibration is the number of glottal opennings per second

fundamental frequency

The higher the fundamental frequency,

the higher the pitchd

Ambiguity cause by structural difference in the senstence

structural/ syntactic ambiguity

The study of our knowledge about he relation between linguistic meaning and our knowledge of the world

pragmatics

Meanings of sentences are determined linguistically in which types of sentences?

analytic sentences

Meanings of these sentences are determined linguistically and pragmatically

synthetic sentences

What are the two functions of birdsong?

mate attraction and defense against other males

Unspecialized acts of structures that have not been modified by selection for communication

cues

Signals that are in the repertoire of most members of a population and can be easily performed

free strategic signals

Signals with hancicaping costs

strategic signals

Argues that the cost will increase the effectiveness of the signal in regards to attracting mates

vulnerabililty handicap hypothesis

Have no intrinsic cost in producing the sound but this signal is regulated by social accords and the responses of signal recipients

conventional signals

Signals intensity is on a continuum

grading signals

Directly reflecting a specific quality of the signaler due to their intensity being inextricably tied to the quality being signaled

index signal

Cost paid by the signaler and not the receiver

receiver independent cost

Depends on the actions of not only the signaler but also the receiver

receiver dependent costs

Intrinsic costs associated w/ signal transmission like making the signal and its information clearly received

efficacy costs

Costs external to transmission that are needed to ensure signal honesty and reliability (handicaps)

strategic costs

The process in which cues are adapted into displays

ritualization

Focuses on how signal evolution depends on the development of cognitive mechanisms to aid signal recipients in processing signals

receiver psychology

Focuses on natural selections effect on signal information provided to recipients

strategic design

Focuses on how that information is transmitted and designed to get to the receiver

tactical desgins

Multimodal signals are made up of components whose implementation provides redundant information

backup signal hypothesis

Components may provide nonredundant information, which would benefit a receiver by providing information about different qulaities of signaler condition

multiple message hypothesis
