Textbook Question
Chapter 1, Problem 1.32ACI
Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on the problem was investigated in the Journal of Behavioral Decision Making (January 2007). A total of 171 volunteer students participated in the experiment, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. Immediately after the task, the students were presented with a decision problem (e.g., whether or not to spend money on repairing a very old car). The researchers found that a higher proportion of students in the guilty-state group chose to repair the car than those in the neutral-state and anger-state groups.
- a. Identify the population, sample, and variables measured for this study.
- b. Identify the data-collection method used.
- c. What inference was made by the researcher?
- d. In later chapters you will learn that the reliability of an inference is related to the size of the sample used. In addition to sample size, what factors might affect the reliability of the inference drawn in this study?

The effect of guilt emotion on how a decision maker focuses on a problem was investigated in a behavioral magazine. A total of 172 volunteer students participated in
the experiment, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. Immediately after the task,
students were presented with a decision problem where the stated option had predominantly negative features (spending money on repairing a very old car). The
results (number responding in each category) are summarized in the accompanying table. Suppose one of the 172 participants is selected at random. Complete parts a

An experiment-based study was conducted to assess the effect of guilt emotion on how a decision-maker focuses on a problem. One hundred seventy-one volunteer students participated in the experiment, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. After the task, students were presented with a decision problem where the stated option had predominantly negative features (e.g., spending money on repairing a very old car). The results (number responding in each category) are summarized in the following table. Is there adequate evidence (at ? = 0.10) to conclude that the option choice depended on the emotional state? Use the data saved to answer the question.

- Store Window Creativity and Shopper Behavior. Do more creative store-window displays affect shopper behavior? Six main-street retailers selling everyday fashion items were used in the study. Pretests with shoppers showed the six stores to be comparable on brands and consumer perceptions of value for the money. Three of the retailers had more creative windows, in terms of displaying items in a more innovative and artistic manner versus the less creative windows, which had a more concrete focus on the items on display. All display windows were of similar dimensions. Observers, in close proximity but out of sight of shoppers, watched their behavior as they passed the display windows, and for each shopper the observers recorded whether the shopper looked at the window or entered the store. A total of 863 shoppers passed the more creative windows and 971 passed the less creative windows. The study found that a higher percentage of shoppers looked at and entered the stores with the more…arrow_forwardCulture and Mental IllnessA recent study1 examining the link between schizophrenia and culture interviewed 60 people who had been diagnosed with schizophrenia and who heard voices in their heads.

As such, they ask a random sample of patients that have used the hospital's health care services to fill out a questionnaire. The questionnaire has questions about the patient's worry (negative, positive), the hospital staff's communication skills (low, medium, high), and satisfaction with medical care. The administrators are interested in how patient's worry and their assessment of the hospital staff's communication impact their satisfaction with medical care. The survey data are below.

- n studies examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that an individual’s sense of humor had a significant effect on how the individual was perceived by others. 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, 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 had 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 attractive) to 7 (very unattractive). A score of 4 indicates a neutral rating. a.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.

Levine, Burgess, and Laney (2008) conducted a study to investigate the effect of children’s emotions on their memory abilities and the likelihood that their memory accuracy would decline due to leading questions about their memories for a story. This knowledge may be useful in determining the conditions under which children’s memories are less likely to be accurate, which is important in various applied situations, such as when children must testify in court about something they experienced. Method of the Study. Four- and six-year-old children participated in the study. Each child was presented with three stories. A task at the end of each story was designed to elicit happiness, sadness, or anger.

Flett, Goldstein, Wall, Hewitt, Wekerle, and Azzi (2008) report the results of a study relating perfectionism to binge drinking. In the study, students were classified into three groups based on the number of binge drinking episodes they experienced during the past month (0, 1, 2 or more). The students then completed a perfectionism questionnaire including one scale measuring parental criticism. One sample item is “I never felt that I could meet my parents’ standards.” Students rated their level of agreement with each item, and the total score was calculated for each student. The following results are similar to those obtained by the researchers.
