Put to the Test
The optimal sampling method for norming a standardized test.
What is random (or probability) sampling?
The use of this type of method tends to differentiate between developmental surveillance and screening.
What are standardized tests?
Difficulties sharing attention and affect, diminished response to name, and the presence of repetitive motor mannerisms.
What are early red flags for ASD?
The mean and SD of many common IQ tests.
What is 100 and 15?
In contrast to IQ tests, developmental tests for this population include multiple domains such as those relating to motor and social-emotional functioning.
Who are infants and toddlers?
To maintain test security, to update norms, and to reflect changes in language, culture, and society.
What are reasons to regularly revise tests.
These were identified with regard to screening based upon race/ethnicity, parental education, primary language, and U.S. state of residence.
What are screening "disparities?"
The current prevalence rate of autism spectrum disorder (ASD) in the U.S.
What is 1 in 44 children?
When is 6 or 7 years?
A diagnosis of Intellectual Disability requires scoring below 70 to 75 on a standardized IQ test and low scores on this.
What is "adaptive behavior?"
This item index is calculated by subtracting the number of low scorers who answered the question correct from the number of high scorers who did so.
What is the "discrimination index?"
The widely-used test developed by T. Berry Brazelton designed to test newborn characteristics such as habituation, autonomic regulation, and motor tone.
What is the Neonatal Behavioral Assessment Scale (NBAS)?
The child’s use of gestures and eye contact to direct others’ attention to objects, to events, and to themselves.
What is initiation of joint attention?
Scores from early developmental tests of infants and toddlers are best thought of as representing this.
What is current developmental functioning?
An advantage of the Wechsler tests having overlapping age ranges is that it allows us to minimize the chance of these.
What are "floor" and "ceiling" effects?
The common name for a "table of specifications" used in the test construction process to ensure appropriate content coverage.
What is a "test blueprint?"
It is recommended that routine developmental screening occur at these intervals.
What are 9, 18 and (24 or 30) months?
Although we have made gains in decreasing overall diagnostic disparities with regard to ASD, these groups still appear to encounter delays in the timing of diagnosis.
Who are Black and Hispanic children?
What is "g factor?"
The Matrix Reasoning subtest of the WISC-V requires a child to recognize a visual pattern and then select an item to complete the pattern. This test contributes to this WISC index.
What is Fluid Reasoning?
The last of the four stages of test development.
What is "plan implementation?"
Developmental screeners are most interested in minimizing this type of incorrect outcome.
What are false negatives (not identifying risk when it is there)?
The most common screening measures for ASD through parent report and direct testing, respectively:
What are the MCHAT-R and the STAT?
Of the three theories of intelligence presented in lecture, this one has the most research evidence and serves as a foundation for many common IQ tests, including the Wechsler series.
What is CHC Theory?
It may not be appropriate to report and/or to make decisions based upon a full-scale IQ score when pattern analysis reveals this.
What are significant discrepancies across different subscales?
