Dr. LaSalle makes the claim: "Research shows that making more money correlates with spending less time talking with your spouse." Which type of claim is Dr. Ramon making?

Causal Claim

Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 words to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A, and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B. Dr. Kang sends his study to a journal to be published. One of the peer reviewers questions the way he manipulated emotion, arguing that being exposed to emotional words does not make one emotional. The reviewer is questioning which of the following validity?

Construct Validity

According to its conceptual definition, a variable should be related to a particular behavior. If a researcher is able to demonstrate that his measure of the variable is related to the behavior, then he has established which validity?

Criterion

Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 words to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A, and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B. If Dr. Kang decided against using random assignment, what validity would he be threatening?

Internal Validity

Temporal Precedence

One variable comes before the other

Dr. Ellison finds a relation between the amount of sleep and problem solving. Specifically, having a higher amount of sleep the night before an exam is associated with higher scores on two measures of problem solving. This is an example of which type of association?

The measure has 15 questions, and it takes 20 minutes to complete. If Dr. Sheffield's measure does not actually measure pathological gambling, his measure is said to lack what?

Validity

If researchers measure every member of a population they have:

census

non-probability sampling

convenience sampling, quota sampling,Purposive sampling, snowball sampling

Another word for observer effects is:

expectancy effects

Random Sampling increases

external validity

Random Assignment increases

internal validity

Face Validity

it looks like what you want to measure
