language sample
A language sample is “recording of a child’s conversational or
naturalistic verbal interaction with the clinician, family member, or both…”
* Not entirely natural(clinic setting)
frequency measures
-Taking a tally of the number of times a client exhibits a behavior during a specific time frame
* Must specify a time frame (e.g., number of times during a 20-minute recess the child initiates
communication with a peer)
Durational Measures
Used to measure the amount of time a behavior occurs
* Suitable for many pragmatic language behaviors (e.g., eye contact, topic maintenance, appropriate
proximity)
verbal interaction sampling
- Involves collecting data on the behavior of your client with at least 1 other individual during social
interaction
criterion-referenced tasks
A Criterion-Referenced Task is used to assess a specific language structure by providing an obligatory context for its production, often when a child has not produced that structure in a language sample.
Why should a language structure not be reported as absent if it was not produced during language sampling
If there was no obligatory context for the structure to be produced, it should not be reported as absent. Criterion-referenced tasks are used to create this context.
What are Criterion Referenced Tasks used to assess?
They are used to assess language structures that were either not produced during the language sample or were produced insufficiently for an adequate sample
How do Criterion-Referenced Tasks differ from norm-referenced assessments?
Criterion-Referenced Tasks are not compared to normative data, but rather to a criterion, such as the expected language skill level for a child with typical development
What is the criterion for assessing child language?
The criterion is the level of language skill expected from a child exhibiting typical development at a certain age
Give an example of a language structure expected for a child aged 27-30 months according to Brown (1973)
A child aged 27-30 (3 year) months should be producing morphemes like the present progressive –ing and plural –s
What should you do if a 3-year-old child does not produce certain morphemes during language sample analysis?
You should present criterion-referenced tasks to further assess those morphemes.
How can you elicit the present progressive –ing morpheme using a criterion-referenced task?
Present pictures or storybooks depicting action and say, “Tell me about this picture.”
How can you elicit the plural –s morpheme using a criterion-referenced task?
Present one object and then multiple objects, and use a sentence completion prompt, such as, “Here is one ball. Here are two
obligatory context
language structure is necessary to complete the sentence or make sense of the communication. for example “Here is one ball. Here are two_____”
psychometrics
measurement of human behavior.
* Involves the design, administration, and interpretation of tests.
i.e., the development of scores, the validity
of a test, the reliability of a test, etc.
norm-referenced tests
includes the measurement of selected behaviors from a sample representative of the population yielding norms.
Provides a range of scores from which an individual
child’s score may be compared.
A language disorder may be diagnosed if the scores
significantly deviate from the average/mean
The norm:
the average performance of a group of children at different age levels
validity
is “…the measure of the test’s ability to assess what it purports to assess” (what it says) (Owens)
reliability
…the repeatability of measurement”
(Owens, 2014, p. 105).
It investigates repeated administrations and the degree to which they are consistent
basal
The basal level varies dependent on the test. Once reached, all testing exemplars preceding it are considered correct.
Usually it is a specified number of consecutively correct answers.
Not always achieved
-starting age range
raw score
the number of items answered correctly.
* Usually, the number of the ceiling item minus the number of errors.
* minimal information in that it allows for the number of correct responses to be known, but no information comparing a score to other individuals of the same age.
* Must be statistically converted into a derived score.
ceiling
Testing exemplars are administered until this is achieved. Once reached all testing exemplars subsequent are considered failed.
The highest item completed is the celing
standard score
The test score of a participant expressed as the deviation of the score from the mean score of the
sample population in units of standard deviation.
- Provides interpretable information where by the individual may be compared to his or her age-matched peers.
- Typically, the mean score and standard deviation are
predetermined to the metric where the mean is standard score of 100 and standard deviation is 15.
mean score
the average score of the normed sample.(population)
