MCAT Theories of Emotion Practice Questions
Ten free MCAT-style practice questions on James-Lange, Cannon-Bard, Schachter-Singer and appraisal theories, the amygdala, autonomic arousal and Yerkes-Dodson, with full explanations.
Quick concept primer
An emotion has physiological, cognitive and behavioral components, and the classic theories differ mainly in order. James-Lange is a peripheral theory: a stimulus triggers bodily arousal, and perceiving that arousal is the emotion. Cannon-Bard is a central theory: the thalamus sends signals at the same time to the cortex (the feeling) and to the hypothalamus and autonomic nervous system (the arousal). Schachter and Singer's two-factor theory says arousal is general and the emotion depends on the cognitive label drawn from the situation. Lazarus put cognitive appraisal of the event first, before both feeling and arousal.
The amygdala detects threat and tags emotional memories, the hypothalamus drives autonomic and hormonal responses, and the prefrontal cortex regulates emotion from the top down. Sympathetic activation raises heart rate, dilates pupils and airways, and slows digestion. Ekman's cross-cultural work suggests a set of facial expressions recognized across cultures, while learned display rules govern when they are shown. The Yerkes-Dodson law describes an inverted U between arousal and performance, with a lower optimum for hard tasks.
Traps: in Cannon-Bard, arousal and feeling occur together, not in sequence. Schachter-Singer starts with arousal that needs a label, while Lazarus starts with appraisal.
10 practice questions
Question 1
A hiker rounds a bend, sees a rattlesnake and freezes. She notices her heart pounding and her hands shaking, and only then concludes that she is terrified. Which theory of emotion does her account most closely match?
- Cannon-Bard theory
- Schachter-Singer two-factor theory
- James-Lange theory
- Lazarus's cognitive appraisal theory
Show answer and explanation
Answer: C. James-Lange theory
James-Lange holds that the stimulus produces bodily changes first and the feeling of emotion is the perception of those changes, exactly the sequence she reports. Cannon-Bard would have arousal and fear occur at the same time. Schachter-Singer requires a cognitive label from the setting, and Lazarus places appraisal of the threat before arousal.
Question 2
Volunteers received an injection of epinephrine or saline and then waited with a confederate who acted giddy and playful. Some epinephrine recipients were told the drug would cause a racing heart and trembling, and others were told it had no side effects. Mean self-rated happiness (0 to 4 scale) is shown.
| Group | Mean happiness rating |
|---|---|
| Epinephrine, told the true effects | 0.9 |
| Epinephrine, told no effects | 2.1 |
| Saline, told no effects | 1.4 |
Which comparison most directly supports the two-factor theory of emotion?
- Epinephrine told no effects is higher than epinephrine told the true effects.
- Saline is higher than epinephrine told the true effects.
- Every group reported some happiness.
- Saline is lower than epinephrine told no effects, showing that arousal alone determines which emotion is felt.
Show answer and explanation
Answer: A. Epinephrine told no effects is higher than epinephrine told the true effects.
Both epinephrine groups had the same arousal. Only those without an accurate explanation looked to the confederate for a label and reported more happiness, which is the core claim of Schachter and Singer that emotion equals arousal plus a cognitive label. The informed group attributed arousal to the drug. Choices B and C do not isolate the role of the label, and choice D contradicts the theory, which says the label, not arousal alone, decides which emotion is felt.
Question 3
Researchers interviewed people with high spinal cord injuries, who receive greatly reduced feedback from the body below the neck. Many reported that they still felt emotions such as fear and anger strongly. This finding most directly challenges which theory?
- Cannon-Bard theory
- James-Lange theory
- Lazarus's cognitive appraisal theory
- The facial feedback hypothesis applied to the face alone
Show answer and explanation
Answer: B. James-Lange theory
James-Lange claims that emotion is the perception of bodily arousal, so a large loss of bodily feedback should greatly weaken emotion. Strong emotion despite that loss fits Cannon's critique that feelings can arise centrally. Cannon-Bard and appraisal theories do not require bodily feedback, and facial feedback would remain intact in these patients.
Question 4
Two students learn they will give a graded presentation. One thinks, "This is a chance to show what I know," and feels eager. The other thinks, "I will embarrass myself," and feels dread. A theorist who explains the difference by saying each student's evaluation of the event's meaning comes first and then produces both the feeling and the bodily response is most closely aligned with
- Richard Lazarus
- Walter Cannon and Philip Bard
- William James and Carl Lange
- Robert Zajonc
Show answer and explanation
Answer: A. Richard Lazarus
Lazarus argued that cognitive appraisal of what an event means for the person precedes and shapes both emotion and arousal, which explains why the same event yields different emotions. Zajonc argued the opposite, that some affective reactions occur before thought. James-Lange and Cannon-Bard do not center on an evaluation of the event.
Question 5
A patient with calcification of both amygdalae is shown photographs of faces. She labels happy and sad faces accurately but cannot identify fearful faces, and she reports little fear when handling a large snake. Damage to the amygdala best explains which of the following?
- An inability to form any new long-term memories
- Loss of fine motor coordination
- Impaired detection of threat and recognition of fear
- A complete loss of autonomic responses
Show answer and explanation
Answer: C. Impaired detection of threat and recognition of fear
The amygdala evaluates threat and generates fear responses, and bilateral damage reduces both fear and recognition of fearful expressions, as in Urbach-Wiethe disease. Forming new explicit memories depends mainly on the hippocampus, and motor coordination depends on the cerebellum. Autonomic control runs through the hypothalamus and brainstem and is not abolished.
Question 6
Walking in the woods at dusk, a man leaps back from a curved shape on the path a fraction of a second before he recognizes that it is a stick. According to LeDoux, which pathway best accounts for the leap?
- A slow route from the thalamus through the visual cortex to the amygdala
- A route from the hippocampus to the cerebellum
- A route from the prefrontal cortex inhibiting the amygdala
- A fast route from the thalamus directly to the amygdala
Show answer and explanation
Answer: D. A fast route from the thalamus directly to the amygdala
LeDoux described a quick, crude path from the thalamus straight to the amygdala that triggers a defensive reaction before the cortex identifies the object. The slower cortical route supplies the detail that it is only a stick. Prefrontal inhibition would calm the response afterward rather than start it, and the hippocampus to cerebellum route is not part of this fear circuit.
Question 7
Volunteers solved either easy or difficult anagram sets under three induced arousal levels. Mean percent correct is shown.
| Arousal | Easy anagrams | Difficult anagrams |
|---|---|---|
| Low | 62 | 41 |
| Moderate | 81 | 58 |
| High | 88 | 37 |
Which statement is best supported?
- Performance on both task types rises steadily with arousal.
- Optimal arousal is higher for easy tasks than for difficult tasks.
- Optimal arousal is the same for both task types.
- High arousal impairs easy tasks more than difficult tasks.
Show answer and explanation
Answer: B. Optimal arousal is higher for easy tasks than for difficult tasks.
Easy-task scores keep rising up to high arousal (88), while difficult-task scores peak at moderate arousal (58) and drop at high arousal (37). This matches the Yerkes-Dodson law: an inverted U whose peak sits at lower arousal for difficult tasks. High arousal helped the easy task, which rules out A, C and D.
Question 8
During a sudden fright, sympathetic activation produces all of the following EXCEPT
- dilation of the pupils
- faster heart rate and greater contractile force
- relaxation of bronchial smooth muscle
- increased salivation and stronger intestinal contractions
Show answer and explanation
Answer: D. increased salivation and stronger intestinal contractions
Sympathetic activation prepares for fight or flight: pupils dilate, the heart beats faster and harder, and airways open. It slows digestion, so salivation and intestinal motility decrease. Increased salivation and gut contractions are parasympathetic, rest and digest effects, which makes choice D the exception.
Question 9
Participants rated cartoons while holding a pen either between their teeth (which forces the muscles of a smile) or between their lips (which prevents smiling). The teeth group rated the cartoons as somewhat funnier. This result is most consistent with which view?
- Cannon-Bard theory, because feeling and expression are independent
- The view that bodily feedback can shape felt emotion, as James-Lange proposed
- Schachter-Singer theory, because participants were misinformed about their arousal
- Display rules, because participants hid their amusement
Show answer and explanation
Answer: B. The view that bodily feedback can shape felt emotion, as James-Lange proposed
Changing facial muscle activity changed felt amusement, the facial feedback effect, which supports the James-Lange idea that feedback from the body contributes to emotion. Cannon-Bard predicts no causal role for bodily feedback. No drug or misattributed arousal was involved, and display rules concern learned norms for showing emotion, not facial posture changing feeling.
Question 10
Students from two countries watched an unpleasant film alone while hidden cameras recorded their faces, and both groups showed similar expressions of disgust. When an authority figure sat with them during a second viewing, students from one country masked their disgust with polite smiles far more than the other group. This difference is best explained by
- differences in the basic emotions each culture can feel
- different facial muscle anatomy across cultures
- the James-Lange theory of emotion
- display rules learned within each culture
Show answer and explanation
Answer: D. display rules learned within each culture
The same expressions appeared when students were alone, which fits Ekman's view that basic facial expressions are shared. The groups diverged only in a social setting, which reflects culturally learned display rules about when emotion may be shown. Nothing suggests different emotions or anatomy, and James-Lange concerns how feelings arise, not social masking.
