vocalization

sounds

respiration

input from your lungs

phonation

involvement of the throat

resonation

Language

only works when we agree what the language is and that it is staying the same name; use them to represent concepts to use arbitrary symbols and rule governed combinations of those symbols

expressive language

what we put out there

receptive language

what we understand

characteristics of language

rule governed and generative

what does it mean when you say language is rule governed

only certain classes of works fit
ex. the WOMAN is in the CAR

what does it mean to say language is generative

we can use language to talk about lots of different things with different terms

What are remarkable features of language

acquisition rate
critical period
universality
species specific

acquisition rate

how quickly people acquire language

critical (sensitive periods)

there's a time where were receptive to learning new language

universality

kids learn language in a predictable way

species specific

humans know their own language (uniquely humans)

What is communication

process of sharing information between 2 or more people:senders and receivers
language must be shared
involves encoding, transmitting, and decoding
used to accomplish something
reliant on language

extralinguistic

these are in addition to the linguistic way of communication

paralinguistic

the tone or emotion or stress of language and really affects the communication

metalinguistic

our ability to think about language as we are using it

nonlinguistic

eye contact, thumbs up, gestures, not verbal

linguistic modes

speak and listen
writing and reading
signing

can you have speech without communication

yes, talking to yourself

can you have communication without speech

yes sign language

can you have language without speech

yes writing

can you have communication without language

no to have communication there has to be some form of language

What are the five components of language

semantics
phonology
morphology
syntax
pragmatics

semantics

understanding of language

phonology

rules governing sounds used to make words

morphology

rules governing internal organization of words

syntax

neuroscience

neuroanatomy and neurophysiology

neurons

basic unit of the nervous system

what are the three parts of a neuron

cell body, dendrites, axon

What is the CNS

brain and spinal cord

what is the PNS

all nerves coming off the spinal column

brainstem

The brain stem controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy. The brain stem

midbrain

serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing.

pons

serves as a message station between several areas of the brain. It helps relay messages from the cortex and the cerebellum.

medulla oblongata

helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing.

reticular formation

a diffuse network of nerve pathways in the brainstem connecting the spinal cord, cerebrum, and cerebellum, and mediating the overall level of consciousness.

thalamus

to relay motor and sensory signals to the cerebral cortex.

cerebral cortex

outer layer of cerebrum where most neurons are found; responsible for reasoning, intellect, motor commands, and sensory interpretation

cerebellum

receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and bal

cerebrum

located above the brainstem, divided into 2 hemispheres;performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

contralateral

info is processed on the opposite side

symmetrical

info is processed equally well on both sides of the brain

What are hemispheres comprised of

grey and white matter

association

within

projection

going form cortex to brainstem

transverse

in a crosswise direction

grey matter

comprised of cell body

lumps

sulci

groves in-between gyri

How old are you when the brain is adult size

12

what are the 3 brain functions

regulation
processing
formulation

regulation

housed in mid-brain, responsible for energy level and overall tone of cortex

processing

managed in posterior portion of cortex, controls information analysis, coding, and storage

formulation

located in frontal lobe (power house) responsible for our intentions and behaviors ( drive car, exit building) activates brain for attention, motor behaviors are coordinated in this function

left hemisphere language

recognizes acoustic features of phonemes (speech perception)
processes language

language comprehension (4 things)

attend to auditory stimulation
auditory signals received in the thalamus and sent to heschls gyrus
coded linguistic info sent to the left temporal lobe and para linguistic info sent to right temporal lobe
requires aid of short term memory

Wernicke's area

left temporal lobe

language production concepts

conceptual basis of message formed in memory areas
messages organized in wenches
transmitted via arcuate fasciculus to..
brocas area in the frontal lobe

arcuate fasciculus

a bundle of axons that connects Wernicke's area with Broca's area; damage causes conduction aphasia

attention
discrimination
organization
memory

discrimination

know what's the most important thing is to pay attention to

organization

link new info to old info, most important step

executive functioning

allocates and coordinates
mental resources
determines cognitive strategies
monitors feedback and outcomes

Big ideas of cognitive, perceptual, and motor bases of language and speech

cognition precedes language development
genetics and environment contribute to learning
learning involves the development of schemes
big changes in memory, speech processing, attention and representational competence in first year of life

neurological development

importance of nature and nurture
brain has all neurons by 6 months
early experiences crucial for activation (make connections)
development proceeds from most basic to higher level functions

what are neonates

newborns

early cognitive development

sensation
perception-auditory
perception-visual
cognition

sensation

sensory function at birth; touch earliest to develop, neonates most attentive to mild stimulation, by 2 months babies can selectively attend; babies experience habituation to familiar stimuli

perception-auditory

newborns can discriminate durations, loudness, phonemes, and consonants; babies learn prosody features, syllable structure and phonetic organization of native language; by 7-8 months children can discriminate intonation patterns, begin spring words; 8-10

synaptogenosis

brain is powerful making connections

Perception-visual

newborns can perceive human face, soon recognizes moms face and expressions; by 4-6 months respond differentially to a smile; with increased memory, recall image with presentation of stimuli

cognition brain structure

neurons are not distributed randomly
early on brain structure is similar across people
changes in response to stimulation
plasticity ability of the brain to recognize

representations (way we organize info in brain)
representational competence (ability to extract similarities)

rules of caregiver

technique:
phasing- knowing when to act
adoptive- talking slower with babies
facilitative-going to have a routine in environment
elaborative- taking what child is doing and then add a little more
initiating- directioning where the chips interaction is
con

Big ideas of the social and communicative bases of language and speech

language is a social tool
social and communicative bases help explain motivation
children communicate before they say words
parental responses matters

newborn communication

usually auditory "hard wired" for communication
interactions

usually and audirotily "hardwired" for communication

visual preference for faces/eyes
hearing in range of human voice
preference for human voice/ esp. moms
moves in synchrony with human voice

interactions

newborns will search for human voice
will stop crying and attend to moms voice
facial expressions engage mom
movement of infant head signals mom

1 month of early communication

gaze at adults face, vocalize
change gaze with partner
match pitch and sound duration of adult
smile in response to familiar face

2 months of early communcation

search for moms voice, turn away from strange voices
recognize familiar people
begin to hear cooing and gooing

3 months of early communication

fun begins
broader intentional social smile
increased interest in the facial expressions of others
beginning to learn that signaling results in charge

3-6 months of early communication

game playing becomes important
increased toy play
vocalizes to accompany attitude

7-12 months

sad when mom leaves, plays in moms presence
infants begin to selectively attend to language follow directions
can follow point and glance

0-8 months

game playing

progress form imitation "copy cat" and other social games to object play
games share many attributes with conversation
games are enjoyable

Big ideas of describing language

there are different theoretical perspectives on how language development occurs
research drives our practice and it is important to understand into about a study sample, method of data collection, nd analysis to evaluate this research
