Textbook Question
Chapter 10, Problem 6E
Mueller and Oppenheimer (2014) conducted a series of studies comparing the effectiveness of taking classroom notes on laptops versus writing longhand. In one study, students were instructed to use their normal classroom note taking strategy using either a notebook or a laptop while they watched a brief lecture. A short time later, the students were given a quiz on the lecture material. Although the quiz results showed no difference between the two strategies for factual questions, the students using longhand had significantly higher scores for conceptual questions. Explain why the researchers cannot conclude that taking longhand notes causes better conceptual learning that taking notes on a laptop.

In this same passage, answer the third question to the problem.
In the Chapter Preview we presented a study showing
that handling money reduces the perception pain
(Zhou, Vohs, & Baumeister, 2009). In the experiment,
a group of college students was told that they were
participating in a manual dexterity study. Half of the
students were given a stack of money to count and the
other half got a stack of blank pieces of paper. After
the counting task, the participants were asked to dip
their hands into bowls of very hot water (122°F) and
rate how uncomfortable it was. The following data
show ratings of pain similar to the results obtained
in the study.

- In a research study, wherein the researcher wanted to know if people’s intelligence is perceived differently based on race, participants observed either a Caucasian, African American, or Asian American stimulus person giving a speech. All stimulus persons gave the same verbal speech. After observing this person, the participants had to rate the stimulus person’s level of intelligence on a scale of 1-10. The participants were separated by gender and their ratings were analyzed separately. How many possible interaction effects might the researcher find?

She conducted a study to see whether children with ADHD had lower scores on measures of verbal intelligence than those without ADHD. She divided children in her study into 4 groups- those clearly diagnosed with ADHD- combined type, those clearly diagnosed with ADHD- inattentive type, those with ADHD symptoms but not clearly diagnosed, and those without ADHD. Then she measured their scores on the Reading Comprehension task, Vocabulary task and Writing Task. What type of statistic did she run?

In one part of the study, female college students were given brief descriptions of a potential romantic partner. The fictitious male was described positively as being single and ambitious and having good job prospects. For one group of participants, the description also said that he had a great sense of humor. For another group, it said that he has no sense of humor. After reading the description, each participant was asked to rate the attractiveness of the man on a seven-point scale from 1 (very unattractive) to 7 (very attractive). A score of 4 indicates a neutral rating. The females who read the “great sense of humor” description gave the potential partner an average attractiveness score of M = 4.53 with a standard deviation of s = 1.04.
