c. bias blind spot FEEDBACK: Intuition Is Biased By Motivation — This is the definition of bias blind spot.

In a developmental psychology class, Trina learned about Baumarind's (1971, 1991) work on parenting styles. She recognized that her parents used an authoritarian style of parenting, as did all her relatives. Since that was the style of parenting she planned to use, she researched the advantages to that style, while ignoring any studies that support the use of another parenting style. What is the term for what she was doing? a. showing a self-serving bias b. confirmatory hypothesis testing c. cherry-picking the evidence d. creating a good story

c. cherry-picking the evidence FEEDBACK: Cherry-Picking the Evidence — She only looked for information that supported her belief that authoritarian parenting was the best style, instead of looking at all of the available information.

What are the differences between PsycINFO and Google Scholar?

PsyINFO searches only sources in psychology plus a few sources from related disciplines. Google Scholar searches only empirical articles and scholarly books. It doesn't allow to search as easily in specific fields

probabilistic

Describing the empirical method, stating that science is intended to explain a certain proportion (but not necessarily all) of the possible cases.

confederate

An actor who is directed by the researcher to play a specific role in a research study.

meta-analysis

A way of mathematically averaging the effect sizes of all the studies that have tested the same variables to see what conclusion that whole body of evidence supports.

How are empirical journal articles different from review journal articles? How is each type of article different from a chapter in an edited book?

Empirical journal articles report for the first time, the results of an empirical research study. Review journal articles are a summary of all published studies that have been done in one research area. Chapters are not peer-reviewed as rigorously as empirical journal articles or review articles.

If you encounter a psychological trade book, what signals that the information it contains is research-based?

The best way to tell is to look at the end of the book, where you may find footnotes or references documenting the research studies on which the arguments are based.

effect size

The magnitude of a relationship between two or more variables.

bias blind spot

The tendency for people to think that compared to others, they are less likely to engage in biased reasoning.

confirmatory hypothesis testing

The tendency to ask only the questions that will lead to the expected answer.

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.

availability heuristic

The tendency to rely predominantly on evidence that easily comes to mind rather than use all possible evidence in evaluating a conclusion.

A school district decides to compare a new math textbook to the textbook that has been in use for the past few years. Each of the fourth graders in one school is assigned to be in one of two classes, one in which a teacher continues using the old book and another in which a new teacher uses the new book. The school administrators compare the average scores of the two classes on a mathematics standardized test at the end of the year to determine which book is better. Which of the following is a potential confound in this study? a. There are different children in fourth grade this year than there were last year. b. The teachers have different amounts of experience using the books. c. The standardized test is graded incorrectly. d. Both classes have children who report that they do not like math.

b. The teachers have different amounts of experience using the books. FEEDBACK: Experience is Confounded — The teachers having different amounts of experience using the book is the only problem that varies systematically along with the textbook version, so it is the only one that could be a confound.
