Cannon-Bard theory of emotion
Emotional experience and bodily arousal can arise in parallel.
Theory The classification describes how this account is used here; it is not an evidence rating.
Central claim
Subcortical central nervous system processing responds to an emotional event by generating subjective emotional experience and peripheral bodily arousal simultaneously and independently.
Proposed mechanism
Central processing of an event generates subjective feeling and bodily activation without requiring the feeling to be produced by sensing the peripheral response first.
Evidence: (Spielman et al., 2020)
What would it predict?
If peripheral feedback is reduced, emotional experience should not necessarily disappear. A convincing test must measure both central processing and the specific feedback pathway affected.
An original test formulation derived from the account, not a claim that this exact study was performed.
Evidence and status
OpenStax presents Cannon (1927) and Bard's (1934) centralist account as a challenge to making peripheral feedback the sole source of feeling. Their critique drew on physiological evidence that visceral changes are too slow and insufficiently differentiated to explain rapid distinct emotions.
Evidence: (Spielman et al., 2020)

Apply the explanation
Original teaching scenario
A person experiences alarm while their body becomes activated after a sudden threat, without first consciously inspecting their heartbeat.
Constructed for learning. This scenario does not report an empirical result.
Common confusion: James-Lange theory or two-factor theory of emotion
Cannon-Bard argues that central processing produces feeling and bodily arousal in parallel without waiting either for peripheral feedback (James-Lange) or for a contextual label of ambiguous arousal (Schachter-Singer).

Evidence: (Spielman et al., 2020)
Limits and alternatives
- Parallel does not mean every process starts at exactly the same measurable instant. Historical localization claims are not a complete map of the distributed systems now studied in affective neuroscience.
Evidence: (Spielman et al., 2020)
