AP Psychology: Motivation and Emotion (Drill 24)

Question 1. During a hiking trip, Daniel steps on what he initially thinks is a snake. His heart races, he feels his muscles tense, and almost simultaneously he becomes aware of feeling intense fear. He then realizes the "snake" was a coiled rope. According to the Cannon-Bard theory of emotion, which of the following best describes what occurred?

• A) Physiological arousal caused Daniel's fear, because emotion results from interpreting bodily changes
• B) Daniel's appraisal of the stimulus produced arousal, and that arousal was then labeled as fear
• C) Physiological arousal and the subjective feeling of fear occurred simultaneously and independently ✓
• D) The rope became a conditioned stimulus through prior pairing with threatening situations

Explanation: Cannon-Bard specifically claims that physiological responses and emotional experience happen at the same time and independently of one another, neither causes the other. That matches Daniel's experience of heart racing and fear arriving together. (A) describes the James-Lange theory, which students frequently confuse with Cannon-Bard, arousal → emotion is James-Lange's signature claim. (B) describes the Schachter-Singer two-factor theory, where arousal requires cognitive labeling. (D) imports classical conditioning from Unit 3; conditioning can create emotional responses, but the question specifically asks what Cannon-Bard would say about this episode, so (D) is accurate on its own but doesn't answer the question. [Practice 1]

Question 2. A researcher wants to test whether physiological arousal alone, without cognitive interpretation, is sufficient to produce a specific emotion like anger or joy. Participants are injected with epinephrine (which produces arousal) and then placed in either a room with a confederate acting euphorically or a room with a confederate acting irritably. This design most directly tests:

• A) The James-Lange theory, by showing that arousal alone determines emotion
• B) The Schachter-Singer two-factor theory, by testing whether cognitive context is needed to label arousal ✓
• C) The Cannon-Bard theory, by isolating arousal from emotional experience
• D) Drive-reduction theory, by measuring how arousal motivates behavior

Explanation: This is essentially the Schachter-Singer experimental paradigm. The design holds arousal roughly constant (via epinephrine) while varying the cognitive/contextual information available to label that arousal. If participants feel different emotions depending on the confederate, cognition matters, which is Schachter-Singer's central claim. (A) reflects a common misconception: the design would contradict James-Lange, not support it, because identical arousal producing different emotions undermines the idea that arousal alone determines emotion. (C) misreads Cannon-Bard, which holds that arousal and emotion are independent, the study doesn't test independence. (D) imports drive-reduction from motivation content; drive-reduction is a real concept, but the study is about emotion labeling rather than arousal motivating behavior, so (D) is accurate on its own but doesn't answer the question. [Practice 2]

Question 3. Maya is preparing for a high-stakes music recital. In the weeks leading up to the performance, she reports feeling low motivation and often skips practice. A performance psychologist suggests that, according to arousal theory, Maya's current arousal level may be too low for optimal performance on her task. Which concept best supports this interpretation?

• A) The Yerkes-Dodson law, which predicts an inverted-U relationship between arousal and performance ✓
• B) Homeostasis, which drives organisms to maintain a stable internal state
• C) Intrinsic motivation, which arises from internal rewards rather than external pressure
• D) The overjustification effect, which reduces intrinsic motivation when external rewards are added

Explanation: The Yerkes-Dodson law holds that performance is best at a moderate level of arousal, too little produces disengagement, too much produces anxiety-driven decrements. The psychologist's claim that Maya's arousal is "too low for optimal performance" is precisely Yerkes-Dodson reasoning. (B) describes a different motivation concept, homeostasis applies to biological drives like hunger and thirst, not to optimal performance arousal. (C) and (D) are both real and important motivation concepts, but they address sources of motivation rather than the arousal-performance relationship the psychologist invoked, accurate on their own but don't answer the question. [Practice 1]

Question 4. Suppose a researcher designs an experiment in which participants are asked to hold a pencil in a way that contracts the muscles typically involved in smiling, while a control group holds the pencil in a way that prevents those muscles from contracting. Both groups rate the same set of cartoons for humor. If participants in the first group rate the cartoons as funnier on average, this result would provide evidence for:

• A) The Cannon-Bard theory, because facial and emotional responses are independent
• B) The facial feedback hypothesis, because activity in facial muscles is proposed to influence emotional experience ✓
• C) Classical conditioning, because smiling has been paired with humor in the past
• D) The James-Lange theory in its original form, because visceral arousal produces emotion

Explanation: The facial feedback hypothesis proposes that activity in facial muscles sends feedback to the brain that can shape or intensify emotional experience, so if forcing a smile-like muscle contraction increased humor ratings, that pattern would provide evidence for the hypothesis. This question is cross-unit because facial feedback connects emotion to Unit 1's biological bases, the mechanism involves somatic signaling. (A) would be contradicted by the hypothetical result rather than supported, because facial expression clearly influenced emotion. (D) is a close but wrong match; James-Lange does posit that bodily states produce emotion, but it specifically emphasizes visceral and autonomic arousal (racing heart, sweating), not voluntary facial muscle feedback, so (D) is accurate on its own but doesn't answer the question. [Practice 1]

Question 5. A study measures two variables across 100 college students over a semester: (1) hours spent engaging in a self-selected hobby, and (2) self-reported well-being. The correlation between hobby time and well-being is r = 0.42. A second study offers students a cash payment for every hour spent on their hobby and finds that, over the following month, average hobby time decreases. Which of the following conclusions is best supported by the combined results?

• A) The positive correlation in the first study proves that hobbies cause increased well-being
• B) The second study is invalid because cash payments always increase behavior
• C) The first study shows a moderate positive association between hobby time and well-being, and the second study is consistent with the overjustification effect reducing intrinsic motivation ✓
• D) Drive-reduction theory explains both findings, because students are reducing a biological drive

Explanation: The first result is a moderate positive correlation, that's what r = 0.42 means, and it does not by itself establish causation. The second result, where adding an external reward decreases a previously self-motivated behavior, fits the overjustification effect: extrinsic rewards can undermine intrinsic motivation. Only (C) accurately describes both findings. (A) overinterprets correlational data as causal, a classic AP trap. (B) overgeneralizes and is factually wrong: rewards do not always increase behavior, as this very study demonstrates. (D) invokes a legitimate theory, but drive-reduction applies to biological needs like hunger and thirst rather than elective hobbies or the effect of rewards on intrinsic motivation, so it is accurate on its own but doesn't answer the question. This is the hard question because (A), (C), and (D) all invoke legitimate psychological concepts, but only (C) correctly interprets both data patterns. [Practice 3]
