Refer tо Reseаrch Study 9.1 belоw tо аnswer the following question. Which of the following is а control variable in Dr. Lonsbary’s study? RESEARCH STUDY 9.1 Dr. Lonsbary is a cognitive psychologist who is curious about how mood affects memory. She recruited 60 high school students and divided them into three groups. One group (A) listened to a 5-minute piece of music intended to make them feel happy (a song entitled “Don’t Worry, Be Happy”). One group (B) listened to a 5-minute piece of music intended to make them feel sad (a song entitled “Alone Again”). One group (C) listened to no music and instead was asked to sit quietly for 5 minutes (thought to make them feel neutral). When a participant would come to her laboratory, she would greet the participant and then ask him or her to draw a card. If the participant drew a 1, 2, or 3, he or she was assigned to Group A. If the participant drew a 4, 5, or 6, he or she was assigned to Group B. If a participant drew a 7, 8, or 9, he or she was assigned to Group C. The participants were then given a CD to listen to based on their group assignment. The CD contained the song selection or 5 minutes of silence. There were no identifying marks on the CD indicating what was contained on the disc. They were then escorted into a different room, where they were greeted by a research assistant who conducted the experiment. The research assistant sat the participants in front of a computer screen and told them that a list of 25 words would be displayed on the screen. They were instructed to put the CD in the computer, put on the headphones, and listen to the CD while trying to memorize the list of words. When 5 minutes had passed, the screen displayed a question asking them whether they felt happy, sad, or neutral. After the participant responded, a new screen was displayed asking them to type in all the words they could remember from the list of 25 words. All participants were given 3 minutes to type the words they remembered. In addition, all participants were given the same list of 25 words to remember. Afterward, the participant was thanked and dismissed. In response to the mood question, a majority of Group A participants said they were happy, a majority of Group B participants said they were sad, and a majority of Group C participants said they were neutral in their mood. Dr. Lonsbary found the following results in response to the number of words remembered. Group A (Happy) Group B (Sad) Group C (Neutral) Number of Words Remembered 16 14 9 Groups A and B vs. Group C Statistically significant difference d = .36 Group A vs. Group C Statistically significant difference d = .30 Group B vs. Group C Statistically significant difference d = .41 Group A vs. Group B No statistically significant difference d = .09

Refer tо Reseаrch Study 12.3 belоw tо аnswer the following question. Which of the following аllows Dr. Anderson to conclude that keeping a food journal caused weight loss in W. J.? --- RESEARCH STUDY 12.3 Dr. Anderson is a nutritionist who helps clients lose weight prior to surgery. She is working with a client (W. J.) who is a male planning on undergoing a heart transplant. He currently eats more than 3,500 calories a day and has been asked by his doctor to cut the number of calories to about 1,800 (400 for breakfast, 600 for lunch, and 800 for dinner). She is curious as to whether a food journal will help reduce the number of calories. A food journal is a book in which a person writes down everything he or she eats. She decides to phase in the food journal gradually, initially only being used at breakfast during the first three days after baseline (days 4–6). During days 7–9, the journal is used at lunch, too, and during days 10–12, it also is used during dinner. Each day, Dr. Anderson’s client sends her the food journal and the number of calories he ate at each meal (as calculated by his wife, whose help she enlisted). The data for Dr. Anderson’s study are below.
Pleаse use the study frоm the previоus questiоn (аlso outlined below аgain):What is the main effect for argument strength? (enter only the value, not a +/- sign) ----------------------------- Brinol and Petty (2003) examined “a new mechanism by which overt head movements can affect attitude change. In each experiment, participants were induced to either nod or to shake their heads while listening to” a message. The message was meant to persuade them of requiring all students "to carry personal identification cards as part of a proposed new university security system". Participants were divided into groups so that they either nodded or shook their heads. Some participants received messages containing convincing, strong arguments for requiring IDs (such as: increased personal security, increased data security, cost and time effectiveness). Others listened to messages with weak, implausible arguments (such as IDs allowed for longer lunches for security officers, the university's image would be improved). The authors predicted that Strong arguments would overall result in more persuasion (i.e. positive views) of the message than would weak arguments Nodding would produce more persuasion than shaking but only when the message contains strong, plausible arguments. With weak, implausible arguments, the opposite would occur: shaking would produce more persuasion than nodding. The table below shows the persuasion scores (how strongly the participants agreed with the message) for the four conditions: Head Movement Nod Shake Argument Weak 60 80 Strength: Strong 90 70
