What is validity in the context of a test?

A judgment of how popular a test is
A measure of how difficult a test is
A measure of how long a test takes to complete
A judgment of how well a test measures what it purports to measure (correct)

How are characterizations of the validity of tests often phrased?

Popular or unpopular
Easy or difficult
Short or long
Acceptable or weak (correct)

What is inherent in a judgment of an instrument’s validity?

A judgment of how expensive the instrument is
A judgment of how attractive the instrument looks
A judgment of how useful it is for a particular purpose with a particular population of people (correct)
A judgment of how old the instrument is

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 Signup and view all the answers

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 Signup and view all the answers

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 Signup and view all the answers

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 Signup and view all the answers

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 Signup and view all the answers
