According to the James-Lange theory of emotion, which of the following correctly describes how emotions arise?

A: The brain detects a threat and signals the body to prepare physiologically, producing the subjective feeling

B: Emotions arise from cognitive appraisal of a situation's personal significance

C: A stimulus triggers a physiological bodily response, and the emotion is the conscious experience of that bodily change

D: A stimulus triggers an emotion and a physiological response simultaneously, with neither causing the other

Correct: A stimulus triggers a physiological bodily response, and the emotion is the conscious experience of that bodily change

James (1884) and Lange (1885) independently proposed that the standard commonsense order is reversed. We do not see a bear, feel fear, and then run — we see a bear, run, and feel fear because we are running. The subjective emotional experience is the perception of the body's own changes (increased heart rate, muscle tension, etc.). The theory makes the radical claim that without the bodily response, there would be no emotion — only cold intellectual recognition of a situation.

What was Walter Cannon's principal empirical argument against the James-Lange theory?

A: James relied exclusively on introspection rather than controlled experimentation

B: Visceral physiological responses are too non-specific, too slow, and too insensitive to account for the richness and speed of emotional experience

C: The theory failed to explain cultural variation in emotional expression

D: Studies showed people with spinal cord injuries had no emotions, disconfirming the theory

Correct: Visceral physiological responses are too non-specific, too slow, and too insensitive to account for the richness and speed of emotional experience

Cannon (1927) raised several powerful objections. First, the same physiological pattern (elevated heart rate, adrenaline release) occurs across many different emotions, making it impossible for the body alone to differentiate fear from anger from excitement. Second, visceral changes are too slow to be the cause of the rapid emotional experience we often have. Third, artificially inducing the bodily states (e.g., by injecting adrenaline) does not reliably produce genuine emotions.

The Cannon-Bard theory proposes that when an emotion-provoking stimulus is encountered:

A: The hypothalamus signals the cortex first (producing feeling), then the body (producing arousal)

B: Physiological arousal and subjective emotional experience occur independently and simultaneously, both triggered by thalamic signals

C: Cognitive appraisal of the stimulus precedes both physiological and subjective experience

D: The autonomic nervous system generates the emotion, which the cortex then labels

Correct: Physiological arousal and subjective emotional experience occur independently and simultaneously, both triggered by thalamic signals

Cannon proposed, and Bard later developed, that the thalamus simultaneously sends signals to the cortex (producing the subjective feeling) and to the body (producing physiological arousal). Crucially, these two streams are independent — the emotional experience does not cause the bodily response and vice versa. This theory placed the brain, rather than the body, at the centre of emotion and anticipated later neuroscientific interest in subcortical emotion circuits.

In Schachter and Singer's two-factor theory (1962), what are the two necessary components of an emotion?

A: A specific physiological signature and a matching cognitive label

B: Physiological arousal (undifferentiated) and a cognitive label applied to explain that arousal

C: An unconditioned stimulus and a conditioned emotional response

D: Core affect (valence + arousal) and a conceptual emotion category from culture

Correct: Physiological arousal (undifferentiated) and a cognitive label applied to explain that arousal

Schachter and Singer proposed that emotional experience requires two components: (1) general physiological arousal, which is non-specific and does not by itself determine which emotion is felt; and (2) a cognitive label that explains why one is aroused, based on the available situational context. The same state of arousal can be experienced as joy, anger, or anxiety depending on how the person interprets their situation. This was a landmark synthesis of somatic and cognitive perspectives.

What did Schachter and Singer's adrenaline injection experiment find in their key conditions?

A: All participants reported the same emotion regardless of social context, showing arousal alone determines emotion

B: Participants who were informed about their arousal symptoms reported stronger emotions than uninformed participants

C: Uninformed aroused participants adopted the emotional tone of a confederate's behaviour (euphoric or angry), while informed participants were largely unaffected

D: Placebo participants reported stronger emotions than aroused participants in all conditions

Correct: Uninformed aroused participants adopted the emotional tone of a confederate's behaviour (euphoric or angry), while informed participants were largely unaffected

In the key conditions, participants received adrenaline injections. Those who were told about the effects (informed) had an internal explanation for their arousal and were less influenced by the confederate. Those who were not told why they felt aroused (ignorant condition) had no ready explanation, and so looked to the situation — a confederate acting euphoric or angry — to make sense of their state. They reported more emotion and behaved more like the confederate. The study is methodologically controversial but historically influential.

Richard Lazarus's cognitive appraisal theory proposes that which factor primarily determines which emotion is experienced?

A: The automatic physiological response to a stimulus, which the brain then labels

B: The person's evaluation of whether a situation is relevant to their goals, and whether it is threatening, beneficial, or involves violation of their values

C: The social context and cultural norms surrounding emotional expression

D: Innate biological programmes activated by specific classes of stimuli

Correct: The person's evaluation of whether a situation is relevant to their goals, and whether it is threatening, beneficial, or involves violation of their values

Lazarus (1991) argued that the nature of the emotion we experience depends on how we evaluate (appraise) a situation, not on the situation itself or on undifferentiated arousal. Two people in the same situation may feel very different emotions because they appraise it differently — one sees an exam as a threat, another as a challenge. The specific emotion is determined by the pattern of appraisal: threat appraisal → anxiety; loss appraisal → sadness; blame of another → anger.

What is the difference between Lazarus's "primary appraisal" and "secondary appraisal"?

A: Primary appraisal evaluates personal relevance and impact; secondary appraisal evaluates available coping resources and options

B: Primary appraisal is automatic and unconscious; secondary appraisal is deliberate and conscious

C: Primary appraisals produce basic emotions; secondary appraisals produce complex or social emotions

D: Primary appraisal produces arousal; secondary appraisal produces the subjective feeling

Correct: Primary appraisal evaluates personal relevance and impact; secondary appraisal evaluates available coping resources and options

Lazarus distinguished two stages of appraisal. Primary appraisal asks: "Is this situation relevant to my goals and wellbeing? Is it threatening, harmful, or beneficial?" It determines whether an emotion is elicited at all. Secondary appraisal asks: "What can I do about this? What are my options and resources for coping?" It influences the type and intensity of the emotion. For example, a threat appraised with high coping potential may produce challenge rather than threat.

True or False: Zajonc argued, contra Lazarus, that affective reactions can precede and occur independently of conscious cognitive appraisal.

Answer: True

The Lazarus-Zajonc debate (1984) is one of the most important disputes in modern emotion theory. Lazarus held that some cognitive appraisal always precedes emotion. Zajonc presented evidence for "affective primacy" — rapid, automatic affective responses that precede or occur independently of deliberate cognition, including the mere exposure effect and subliminal conditioning studies. This debate shaped subsequent work on the role of the amygdala in fast emotional processing and on dual-process accounts of emotion.

Lisa Feldman Barrett's theory of constructed emotion challenges traditional emotion theories by proposing that:

A: Emotions evolved in discrete neural circuits in subcortical regions such as the amygdala

B: Each discrete emotion has a unique and replicable physiological fingerprint

C: The brain is a predictive organ that uses past experience and cultural emotion concepts to construct emotional episodes; there are no fixed emotion circuits

D: Emotion categories are universal and biologically determined, appearing cross-culturally and in infants

Correct: The brain is a predictive organ that uses past experience and cultural emotion concepts to construct emotional episodes; there are no fixed emotion circuits

Barrett's theory (2017) rejects the "classical view" that the brain has discrete, evolutionarily ancient circuits for fear, anger, etc. Instead, drawing on predictive processing neuroscience, she argues that the brain constantly predicts its sensory inputs based on past experience. When interoceptive (bodily) signals arrive, the brain constructs an emotional experience by drawing on culturally learned emotion concepts. Emotions are not "found" in the brain but actively made. This has significant implications for emotion measurement and clinical intervention.

Which statement most accurately summarises how the major emotion theories differ on the question of physiological specificity?

A: All five major theories agree that different emotions have distinct physiological signatures

B: James-Lange requires that different emotions feel different because they produce different bodily states; Schachter-Singer requires only undifferentiated arousal; Barrett's theory challenges whether reliable physiological fingerprints exist at all

C: Only Barrett's theory acknowledges a role for physiology in emotion

D: Cannon-Bard is the only theory that assigns a causal role to the brain

Correct: James-Lange requires that different emotions feel different because they produce different bodily states; Schachter-Singer requires only undifferentiated arousal; Barrett's theory challenges whether reliable physiological fingerprints exist at all

The theories take starkly different positions on bodily specificity. James-Lange requires distinct bodily patterns for each emotion — that is how we distinguish them. Cannon refuted this, arguing the body is too non-specific; his theory places differentiation in the brain. Schachter-Singer follows Cannon in treating arousal as undifferentiated — the cognitive label does the differentiating. Barrett goes further: large meta-analyses of emotion physiology and neuroimaging find no reliable "fingerprint" for individual emotions, supporting her view that emotions vary considerably within and between people.
