Alex has just finished planning a study to explore whether personality traits can predict how open adults are to altering their beliefs when presented with findings from scientific studies. Before beginning to collect data, Alex preregisters his hypothesis. One of the primary benefits of preregistering his hypothesis is that • it allows him to design a rigorous study focused on empirically testing his hypothesis. • he is less likely to be suspected of developing his hypotheses after analyzing his findings. • he is less likely to develop an incorrect hypothesis • it prevents other researchers from testing the same hypothesis.

he is less likely to be suspected of developing his hypotheses after analyzing his findings.

RESEARCH STUDY 5.2: Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete To test his measure, Dr. Sheffield gives his measure to a group of people in Gamblers Anonymous (GA) and another group of people in Alcoholics Anonymous (AA). He finds that people in the GA group have higher scores on his new measure than people in the AA group. This procedure is known as a • known-groups paradigm • prediction paradigm. • group evaluation paradigm • test-retest paradigm. A

RESEARCH STUDY 3.4: 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.

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.

I am not sure you can really measure being bullied. Quinn also questions the study, saying, "Which middle school students did they study? I am curious if they included both private and public school students." Manish is also curious about the study, asking. "I wonder how strong the relationship is between bullying and self-esteem.

Dr. Avery reads about a new theory that argues that depression is caused by increased levels of estrogen in the womb. To test this theory, she conducted a study comparing the level of estrogen in amniotic fluid in individuals who were later diagnosed with depression with the level of those who did not develop depression. Dr. Avery found no differences between the groups in estrogen levels in the amniotic fluid. Based on these results, Dr. Avery should conclude that • previous studies that support the theory are probably flawed. • there may be unexamined factors influencing the results that contributed to the results of other studies on this topic. • she has disproved the previous theory because the lack of findings contradict her theory. • there is no way to prove the theory because of flaws in the methodology used by Dr. Avery to test her theory.

there may be unexamined factors influencing the results that contributed to the results of other studies on this topic.

Danesh has just read an article that describes a study that used a survey completed by participants to assess anxiety levels in adults.

However, there is no information about interrater reliability. Which of the following reasons explains why the authors do not report interrater reliability? • Since the study has good internal reliability, ¡is not necessary to report interrater reliability • Interrater reliability is typically calculated only for the experimenter to evaluate the ratings and is rarely reported in journal articles. • The combination of internal reliability and test-retest reliability provide enough information about the study's reliability. • The anxiety scale is a self-report measure, and interrater reliability is needed only when two or mor

• The anxiety scale is a self-report measure, and interrater reliability is needed only when two or more observers are providing ratings.
