Unit 1 Flashcards
(168 cards)
descriptive research
data collected that looks at central tendency (mean, median, mode, standard deviation); information related to averages
Ex: surveys studies
experimental research
make group comparisons; they types of studies we want as SLPs, more conclusive and scientific in directing our clinical practices
inferential statistics
taking the results of studies and generalizing it to similar clients
SIG
special intrest group
Language disorder
when a person falls -1.5 standard deviations below the mean on 4 or 5 test called a known language disorder
5 components of language
phonology, morphology, pragmatics, syntax, semantics
bloom and lay components of language
gave three components of language
form- phonology, syntax, morphology
content- semantics
function- pragmatics
Larry Leonard
Purdue University
at risk for a language disorder if a person falls at or below -1.25 standard deviations below mean 10% or lower
language disorder as defined by Tomblin
(university of Iowa)
the degree of being disvalued by society because of language
Language delay
only use the term language delay when referring to very young children
suggests that while a child is behind on language now, they will later catch up
can be very misleading because a delay can develop into a disorder if not acted upon
at -1.25 would have a delay because they are at risk
pl 99-457
-free and appropriate developmental services
-for children with know communication disorder and at risk for communication disorders
“Late talkers” turn into disorders
there is no set definition for these terms that all professionals follow
with most language disorders children
follow the normal acquisition stages, it is just slower
will never go away
Norm Chompsky
studied linguistics
theory of language acquisition that some still believe in
-innate language acquisition
-your brain is wired to learn and develop language from birth
-you only need a little bit of language stimulation to acquire language
he thinks of language in a modular approachnot as many people from speech pathology adapt that theory, they understand it utmost SLPs don’t always embrace that theory
modular approach
Norm chompsky there is someplace in the brain that is a module that is strictly linguistic in nature and language acquisition comes from it
information processing theory
deals primarily with working memory working memory Cognitive Science ***Allen Baddeley and Hitch -limited capacity model
limited capacity model
your brain is only able to hold on a certain amount of information
-children with language disorders have a limited capacity model (difficulty with working memory)
if you cannot hold onto language information, you will have problems in many areas of your life
can be related to language and attentional resources (being able to attend)
Baddeley and Hitch
first to make a model of working memory used to explain language acquisition
working memory
necessary to learn, reason, and remember
processing information and then manipulating that information
does not improve-you are born with a fixed capacity system
those with LD do not have an normal capacity system and that will not improve, we can only help them become more efficient
will see the most on this in the field when looking at articles
where you process and store information
you have to process and store simultaneously
ex: listen to the sentence and say whether it is true or false and what the last word is
not all children with LD have problems with working memory
-language may just be hard for them-may be strictly linguistic in nature
short-term memory
not the same as working memory
holding information in your memory while doing no computation
no second simultaneous task
repeating numbers given to you
long-term memory
learned something and practiced it so many times that it is permanently stuck in your brain
The phase or type of memory responsible for storage of information for an extended period of time
episodic memory
impacts long-term memory
related to personal events, objects, situation that are important in your life
an episode that is important to the rememberer
can be used to help facilitate learning for children with language disorders
Theoretical construct of memory and Baddeley
Baddeley’s model includes
the phonological loop the visual spacial sketchpad, the central executive and episodic buffer
all parts come together to help out long term memory
central executive
the boss, can dictate tasks to the phonological loop the visual spacial sketchpad, and episodic buffer
it knows when the system is over loaded and will throw information out
phonological loop
deals with verbal information
articulatory rehearsal mechanism
phonological store
sub vocal speech mechanism that helps people hold on to information they are trying to remember
as the numbers are listed to you you start to loop them in your head, then they go into the store to be somewhat permanent and no longer needs rehearsed
children with LD have problems recycling them and storing for later recall
this is the part that children with SLI struggle with
visual spacial sketch pad
***primarily responsible for holding visual and spacial information in the brain
we don’t know as much about it as the phonological loop
