## Two-Factor & Appraisal

**Stanley Schachter** and **Jerome Singer** proposed the **Two-Factor Theory** in 1962: emotion requires BOTH physiological arousal AND a cognitive **LABEL** drawn from the context. In their classic study, adrenaline-injected participants placed with a euphoric or irritated confederate adopted that state when they lacked a true explanation for their arousal.

This explains **misattribution of arousal**, as in the **Capilano Suspension Bridge study** (Dutton & Aron, 1974), where men crossing a high, wobbly bridge misattributed lingering arousal to attraction toward a female interviewer.

| Theory | Core claim |
|---|---|
| James-Lange | Arousal, then emotion follows |
| Cannon-Bard | Arousal and emotion occur simultaneously |
| Schachter-Singer | Arousal PLUS a cognitive label |

## Appraisal & Pitfalls

**Richard Lazarus**'s **cognitive appraisal theory** argues that an appraisal — even a rapid, automatic one — must occur BEFORE emotion arises. The same physical bump can trigger fear or amusement depending entirely on how the situation is appraised.

> **Common pitfall:** assuming the two-factor theory says the **LABEL** alone creates emotion without arousal. Schachter and Singer require BOTH ingredients together; neither factor is sufficient on its own.

## Practice questions

7 of this lesson's 12 practice questions, with answers. The full set is in the app.

### 1. Participants asked to hold a pen **between the teeth**, forcing a smile, rated cartoons as funnier than those holding it in their lips. What does the facial feedback hypothesis claim about this?

A. That smiling improves visual attention, so more of the cartoon was processed
B. That the emotion caused the expression, which the pen merely made visible
C. That participants guessed the purpose and complied with what they thought was expected
D. That expression feeds back into experience, not only displays it

**Answer:** D. That expression feeds back into experience, not only displays it

**Why:** The claim is that the arrow runs both ways, expression is an input as well as an output. The pen exists to prevent demand characteristics, since nobody is told to smile. Worth noting the effect has replicated inconsistently, which is why it is now stated more cautiously than in the textbooks.

### 2. Men who met a woman on a swaying suspension bridge were far more likely to call her afterwards than men who met her on a solid one. What does two-factor theory claim happened, and what is the strongest objection?

A. Nothing happened that requires explanation, since the two bridges attracted men of different ages.
B. The bridge produced arousal the men labelled as attraction.
C. The men on the high bridge were genuinely more attracted, so the study demonstrates that fear causes attraction directly.
D. The arousal itself carried the emotional content, which is why it was experienced as attraction rather than fear.

**Answer:** B. The bridge produced arousal the men labelled as attraction.

**Why:** A pounding heart on a swaying bridge needs interpreting, and the most salient thing available is an attractive person asking questions. The objection is selection: nobody was assigned to a bridge, and men who cross precarious ones may differ. The finding survives because the effect reproduces where assignment *is* controlled, arousal from exercise, misattributed the same way.

### 3. James-Lange, Cannon-Bard and Schachter-Singer all concern the same two ingredients - bodily arousal and felt emotion. Why do they nonetheless make different predictions rather than describing the same process in different words?

A. Because later theories simply restate the earlier ones.
B. Because each concerns a different set of emotions.
C. Because only Schachter-Singer makes empirical claims.
D. Because they disagree about the order and role of the ingredients.

**Answer:** D. Because they disagree about the order and role of the ingredients.

**Why:** The three arrange the same vocabulary differently and the arrangements have consequences: James–Lange predicts distinct emotions need distinct bodily states, Cannon–Bard that neither causes the other, Schachter–Singer that arousal supplies how much and cognition which. Modern work suggests no single arrangement covers every case.

### 4. Under two-factor theory an emotion needs both physiological arousal and a cognitive label; neither alone produces it.

**Answer:** True

**Why:** True. Schachter and Singer gave adrenaline with or without an explanation and varied the social cue: arousal alone produced no specific emotion, and a label with no arousal produced none either. It is why the same racing heart is read as fear on a bridge and attraction in company.

### 5. James-Lange puts arousal before emotion, Cannon-Bard makes them simultaneous, Schachter-Singer needs arousal plus a label. What is the disagreement really about?

A. Whether emotions exist at all as distinct from behaviour
B. Whether emotions are universal across cultures
C. Where the content of an emotion comes from
D. Which part of the brain generates emotional responses

**Answer:** C. Where the content of an emotion comes from

**Why:** They agree on the physiology and differ on what makes it a specific emotion. Schachter and Singer's bridge study is decisive precisely because it holds arousal fixed and varies only the label.

### 6. Select every statement that is TRUE about theories of emotion.

A. The two-factor theory requires both arousal and a cognitive label.
B. Schachter-Singer says the label alone is enough, with no arousal needed.
C. Lazarus argued a cognitive appraisal must precede emotion.
D. Misattribution of arousal can make bridge-induced arousal feel like attraction.
E. James-Lange holds that arousal precedes and produces the emotion.

**Answer:** A. The two-factor theory requires both arousal and a cognitive label.; C. Lazarus argued a cognitive appraisal must precede emotion.; D. Misattribution of arousal can make bridge-induced arousal feel like attraction.; E. James-Lange holds that arousal precedes and produces the emotion.

**Why:** Two-factor's dual requirement, James-Lange's ordering, Lazarus's appraisal-first claim, and misattribution of arousal are all true. Schachter-Singer does NOT say the label alone suffices - arousal is required - making that the one false option.

### 7. A man crosses a swaying bridge, meets an interviewer, and later describes himself as strongly attracted to her. Order the steps two-factor theory says produced that feeling.

**Answer:**

1. The bridge sways and his heart rate, breathing and palms all react.
2. The arousal itself carries no label: it could be fear, excitement, or attraction.
3. He scans the situation for what is causing it.
4. The most salient candidate present is an attractive person talking to him.
5. He experiences the arousal as attraction and acts on it later.

**Why:** Step two is where the whole theory lives. Schachter and Singer's claim is that physiological arousal is emotionally ambiguous - a pounding heart is a quantity, not a feeling - and it is the cognitive appraisal of the situation that determines which emotion is experienced. Change what is salient in the environment and the same arousal becomes a different emotion.

That is what makes misattribution possible, and misattribution is the theory's most testable prediction. A man on a solid bridge has no arousal to explain and reports ordinary interest; the man on the swaying bridge has arousal that the bridge could account for and attributes it to the person instead.

It is worth noting where the theory has been challenged. Some arousal states appear to be more physiologically distinct than the theory allows, and the original Schachter-Singer experiment has replicated inconsistently. What has survived robustly is the narrower claim: arousal from one source can be transferred to another and intensify whatever emotion the situation suggests.
