Sasha believes that she is a nice person. To confirm this, she asks all her friends whether she is a nice person and they all agree that she is. Sasha concludes that she is a nice person and says she has evidence of it. Which of the following should Sasha do to prevent Cherry-picking evidence for her belief?

the two biases of intuition discussed in the text are:

Being swayed by a good story and being persuaded by what comes easily to mind.

categorical variables

Categorical variables take on values that are names or labels. The color of a ball (e.g., red, green, blue), gender (male or female), year in school (freshmen, sophomore, junior, senior). These are data that cannot be averaged or represented by a scatter plot as they have no numerical meaning.

A psychiatrist is testing a drug that treats depression. He has given the drug to all his patients and all of them have experienced a decrease in depressive symptoms. Although this is interesting, his experience is limited because he does not have a:

Comparison group that did not receive the drug

What do causal claims and association claims have in common?

Frequency claims measure a single variable, while association and causal claims measure more than one.

What does it mean that behavioral research is probabilistic?

Inferences drawn from behavioral research are not expected to explain all cases.

Initial report, methods, statistics, results

Which of the following is the reason that scientific journals use peer review?

It ensures that the studies published are of the highest quality.

Make sure the identity of peer reviewers is unknown

face validity

Measures whether a test looks like it tests what it is supposed to test.

Patrick is confident that his short-term memory is better than most people's. He knows this because compared with his friends, he can remember more names than they do. Which of the following should we do?

Not believe that his short-term memory is better than most people's because confidence does not ensure accuracy

present/ present bias

The tendency to rely only on evidence that is present (e.g., instances in which both a treatment and a desired outcome are present) and ignore evidence that is absent (e.g., instances in which a treatment is absent or the desired outcome is absent) when evaluating the support for a conclusion. ex- "every time it rains I am late"

Researchers at a beverage company conclude from an intial study that their new mineral water does not improve the metabolism or promote health. Many followup studies conclude that the water has does have health benefits. What kind of mistake did the first study make?

Type II Error; It claimed the water had no health benefits when in fact it did.

Vanessa claims that she sleeps better when she falls asleep to music. She has a comparison group, because she has noticed that she does not listen to music every night, only when she remembers to plug in her iPod. She typically remembers her iPod on nights when she is able to finish studying earlier. What problem do you see in Vanessa's reasoning about sleeping better to music?

Vanessa may be sleeping better because she is less distracted by studying/going to bed sooner.

The problem with the Availability Heuristic is which of the following?

We do not examine all of the evidence, only what we can quickly think of.

What is the argument? and What is the evidence to support the argument?

He knows that he cannot tell them the real reason, but he is unsure whether he should deceive them (give them a false reason why he is waking them up) or provide them with no cover story at all. Which of the following issues should be considered most heavily when deciding whether or not to use deception?

Whether he can conduct the study just as well without deception

content validity

a measure must capture all parts of a defined construct -an IQ test must measure intelligence with different parts.

ratio scale

a quantitative scale of measurement in which the numerals have equal intervals and the value of zero truly means "nothing" -number of exam ?'s correct

interval scale

a scale of measurement in which the intervals between numbers on the scale are all equal in size. no true zero -IQ score, shoe size

operational definition

a statement of the procedures (operations) used to define research variables. For example, human intelligence may be operationally defined as what an intelligence test measures.

measured variable

a variable in an experiment whose levels are observed and recorded

data fabrication

____________ is the approach of collecting data and using it to develop, support, and/or challenge a theory.

empiricism

availability heuristic

estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common

criterion validity

evaluates whether the measure under consideration is related to a concrete outcome, such as behavior, that it should be related to, according to the theory being tested -is a salesperson test measuring their correlation to sell.
