Suppose a researcher is interested in examining the effects of mood and food deprivation on eating. Female participants listen to one of two types of music to induce either a happy or a sad mood, following either 19 hours of food deprivation (breakfast and lunch are skipped) or no deprivation. The participants are then given free access to food in a controlled laboratory setting, and the amount of food consumed is measured for each individual.
How many independent variables or factors does this study have? What are they?
Describe this study using the notation system that indicates factors and numbers of levels of each factor.
Use a matrix to diagram the structure of the study.
In a recent experiment, participants were to take 7,000 steps per day. Group A received a payment of
$1.40 per day if they achieved the goal. Group B received a lump sum payment of $42; $1.40 was
deducted daily for each day they did not achieve their goal. At the end of the experiment, Group B was
significantly more successful in achieving the 7,000 steps per day. Upon which of the following
behavioral economics concepts was this experiment based?
O Setting defaults
O Doing the right thing
O Creating anchors
O Loss aversion
A person who is walking down the street and encounters a large snarling dog may sense that he or she is in danger. That person then feels anxious (body sensation) and quickly turns down the nearest side street to avoid the dog (behavior).
Which theory of emotion is this?
The Opponent Process Theory The James-Lange Theory The Cannon-Bard Theory The Theory of Cognitive Appraisal The Commonsense Approach

- The prefrontal cortex receives extensive input from the amygdala, and it uses information about emotion to make the final determination about whether to engage in a specific behavior. Bechara and his colleagues conducted a study on decision-making that compared healthy individuals to patients with damage to the prefrontal cortex. Which of the following statements about this research is FALSE? A) Over time, patients with prefrontal injuries did not produce anticipatory reactions (sweating) before making a "risky" decision. B) At first, both groups of individuals chose the "risky" option more often. C) Both the healthy individuals and the patients eventually switched to the "safer" option once they figured out how the game worked. D) Over time, healthy individuals began to produce a strong anticipatory reaction (sweating) before making a "risky" decision.arrow_forwardWhich are the four perspective of ordinary motivated behavior?arrow_forwardOxycontin is a drug used to treat pain, but it is well known for its addictiveness and danger. In a clinical trial, among randomly selected subjects treated with OxyContin, 52 developed nausea and 175 did not develop nausea. Among other randomly selected subjects given placebos, 5 developed nausea and 40 did not develop nausea. Use a 0.05 significance level to test the claim that the proportion of nausea is different for those on OxyContin than for those who are on placebo. Use the critical value method.

- In the Posner cueing paradigm, the participant maintains fixation at the central point. Cues indicate whether the target will appear on the left or the right. In most trials, the cue is valid; that is, the target appears on the indicated side. But in some trials, the cue is invalid; that is, the target appears on the opposite side of the cue. The experimenters measure the reaction time to indicate that the target is present. The results show that ______. Question 58 options: participants are relatively faster when the cue is invalid reaction time increases for valid trials participants are relatively faster when the cue is valid maintaining fixation reduces reaction time significantly The Chan Shun concert hall in Vancouver has excellent acoustics.

- This theory argues that all emotions have similar bodily response patterns.These factors include the person’s analysis of the situation and the ways other people are reacting in the same situation. When other people are involved in the same situation, an individual will look at the way they are reacting and then compare his or her reaction to theirs to arrive at what seems to be the right response.

Participants complete 120 trials. On each trial they choose to flip over a card from one of two decks of face down cards labeled deck 1 and deck 2. Each card flipped over wins or loses an amount of money. In deck 1 (the “bad deck”), 9 out of 10 cards wins $100 but one out of ten cards loses $1250. In deck 2 (the “good deck”), 9 out of 10 cards wins $50 and one out of ten loses $250. The researcher measures the number of choices from the “good deck” versus the “bad deck”, and measures anticipatory skin conductance responses immediately before participants choose from the “good deck” compared to the “bad deck”. The research finds that after experiencing wins and losses from 60 choice trials, control group participants on average begin to choose the “good deck” more…arrow_forwardA researcher has designed a card choice task to better understand altered decision making in a group of patients who have sustained damage to their ventromedial prefrontal cortex (compared to a non-damaged control group).
