10 Questions
What is validity in the context of a test?
A judgment of how well a test measures what it purports to measure
How are characterizations of the validity of tests often phrased?
Acceptable or weak
What is inherent in a judgment of an instrument’s validity?
A judgment of how useful it is for a particular purpose with a particular population of people
What is meant when a test is referred to as a 'valid test'?
The test has been shown to be valid for a particular use with a particular population of test-takers at a particular time
Is any test or measurement technique 'universally valid'?
No, tests may be shown to be valid within reasonable boundaries of a contemplated usage
Match the following brain development stages with their corresponding age:
Newborn baby = Can see, hear, and feel Age of three = Has a hundred trillion connections in the brain Age of five = Can talk, ride a bike, and invent imaginary friends 2010 study findings = Experiences in first few years affect brain development
Match the following sensory information with their role in brain development:
Sight, hearing, smell, taste, touch = Create connections between different parts of the brain Images of babies' brains while listening to sounds = Showed more activity in the speech-related part of the brain during specific sound patterns Different sound sequences = Demonstrated that babies can distinguish between patterns Experiences in first few years = Affect the development of the brain
Match the following findings with their implications on brain development:
Experiences in first few years affect brain development = Children who received more attention often had higher IQs Brain of a newborn baby has nearly a hundred billion neurons = Same number as an adult's brain At the age of three, there are a hundred trillion connections = Result of information received through senses creating connections between different parts of the brain Images of babies' brains while listening to sounds = Showed that babies can distinguish between different patterns
Match the following technological advancements with their impact on understanding brain development:
Scientists using new technology to 'see' into children's brains = Discovering new information about the way a baby's brain develops One experiment looked at images of babies' brains while they were listening to different sounds = Showed that the part of the brain responsible for speech was more active during specific sound patterns 2010 study findings = Showed that experiences a child has in their first few years affect the development of the brain The experiences a child has in their first few years affect the development of the brain = Shown in a 2010 study
Match the following sound sequences with their corresponding brain activity:
Mu-ba-ba pattern (A-B-B) = Part of the brain responsible for speech was more active during this pattern Mu-ba-ge pattern (A-B-C) = Demonstrated that babies can tell the difference between different patterns Different sound sequences = Used to study brain activity while listening to sounds Experiences in first few years affect brain development = Shown in a 2010 study
