AP Syllabus focus:
‘Positive emotions broaden awareness and encourage new thoughts and actions, while negative emotions narrow thinking and behavior.’Broaden-and-build theory explains why different emotions push attention and action in different directions.
Broaden-and-build theory is often taught as an “upward spiral”: positive emotions broaden attention and behavior (leading to novel thoughts, actions, and relationships), which then build enduring personal resources (e.g., skills, resilience, social support). Those accumulated resources feed back into better well-being and create more opportunities for future positive emotion. Source
For AP Psychology, focus on how positive emotions expand possibilities and resources, while negative emotions prioritize rapid, protective responding.
Core idea: broaden vs. narrow
Broaden-and-build theory
Broaden-and-build theory: the view that positive emotions broaden momentary thought–action repertoires (what you notice and can do) and, over time, build durable personal resources.
This framework is most often associated with Barbara Fredrickson and is used to explain how emotions contribute to adaptation beyond immediate survival.
Positive emotions broaden
In the syllabus language, positive emotions broaden awareness and support exploration. Broadening shows up as:
These hierarchical letter stimuli (Navon figures) illustrate the difference between attending to the global pattern (the large letter) versus the local elements (the small letters composing it). In broaden-and-build terms, a broader attentional scope aligns with processing the “big picture,” whereas narrowed attention prioritizes fine-grained, detail-level information. Source
Wider attention: noticing more cues in the environment (more open, flexible focus).
More cognitive flexibility: generating more ideas, seeing alternative interpretations, making novel connections.
Expanded action tendencies: approaching, exploring, playing, learning, connecting.
Common positive emotions discussed in this theory include joy, interest, contentment, gratitude, love, and hope. The key is not that all pleasant feelings are identical, but that many of them increase openness to information and options.
Building: how broadened moments create lasting resources
“Build” over time
Broadened thinking and behaviour can accumulate into enduring resources, meaning capacities that last beyond the emotion itself:
Cognitive resources: knowledge, problem-solving strategies, creativity, perspective-taking.
Psychological resources: resilience, optimism, self-efficacy-like confidence in coping, meaning-making.
Social resources: stronger relationships, trust, social support networks.
Physical/behavioural resources: healthier routines, skill development through play/practice, stress-recovery patterns.
Upward spirals
Repeated experiences of positive emotion can create upward spirals:
Positive emotion → broader attention and actions
Broader actions → more learning/connection/success opportunities
New resources → greater likelihood of future positive emotion and effective coping
In practice, this helps explain why small, frequent positive experiences (e.g., belonging, gratitude) can have outsized effects on long-term well-being.
Undoing effect (stress recovery)
A common claim in this literature is that positive emotions can “undo” some lingering physiological and cognitive effects of negative emotions by supporting calmer appraisal and quicker return to baseline after stress. The AP-relevant takeaway is that positive emotion can facilitate recovery and re-engagement with flexible thinking.
Negative emotions narrow
Narrowing supports immediate survival
The syllabus emphasises that negative emotions narrow thinking and behavior. Many negative emotions (e.g., fear, anger, disgust) are linked to focused, urgent responses:
Attentional narrowing: prioritising threat-relevant information, filtering out distractions.
Constricted action tendencies: fewer dominant options such as fight, flight, freeze, avoid, reject.
Fast, efficient decisions: relying on well-practised or automatic responses under pressure.
This narrowing can be adaptive in dangerous situations because it increases speed and coordination. The trade-off is reduced creativity and openness, which can be costly in complex social or academic contexts where flexible thinking is useful.
When narrowing becomes maladaptive
Negative emotions can become unhelpful when:
The perceived threat is chronic or exaggerated.
Narrowed attention locks onto rumination or worst-case interpretations.
Avoidance reduces opportunities to build competence or social support.
Broaden-and-build does not claim negative emotions are “bad”; it claims their primary function is different: protect now, rather than expand and grow.
What to look for on AP-style prompts
Distinguishing broaden vs. narrow in scenarios
When classifying an example, focus on the immediate effect of emotion on:
Attention (wide vs. tight focus)
Cognition (flexible/generative vs. rigid/urgent)
Behavioural options (many exploratory actions vs. few protective actions)
Time scale (long-term resource building vs. short-term threat response)
Common misunderstandings
Broadening is not the same as “being distracted”; it refers to adaptive openness to information and possibilities.
Negative emotions can be appropriate and functional; the theory contrasts functions, not moral value.
Building is gradual; one positive event may broaden briefly, but durable resources typically require repetition and practice.
FAQ
Not necessarily. High-arousal positives (e.g., excitement) and low-arousal positives (e.g., contentment) may broaden in different ways.
Some “positive” states can also narrow focus if they are approach-intense or goal-fixated.
Common approaches include attention tasks (global vs local processing), creativity measures, and assessments of cognitive flexibility.
Studies may also code behavioural choices for exploration versus avoidance.
Yes. People can experience blends (e.g., pride with anxiety), producing competing tendencies.
Which pattern dominates often depends on context, intensity, and what feels most urgent.
Positive emotions can increase approach and warmth, making social interaction more likely.
Over time this can build social resources such as trust, reciprocity, and support that buffer later stress.
Some findings vary by culture, task, and emotion intensity.
Critics note that measurement choices and publication bias can affect estimates, and that not all studies find strong “undoing” or broadening effects.
Practice Questions
Explain what the broaden-and-build theory predicts about the effects of positive emotions on attention and behaviour. (3 marks)
1 mark: States that positive emotions broaden awareness/attention.
1 mark: States that positive emotions encourage new thoughts and actions (expanded thought–action repertoire).
1 mark: Links broadening to exploration/openness (e.g., noticing more options, trying new behaviours).
A student feels anxious before presenting and focuses only on possible mistakes. Later, after supportive feedback, the student feels grateful and starts planning new ways to improve. Using broaden-and-build theory, explain how negative and positive emotions influence thinking and behaviour in this scenario. (6 marks)
1 mark: Identifies anxiety as a negative emotion.
1 mark: Explains negative emotions narrow thinking/behaviour (tight focus on threat/mistakes).
1 mark: Notes narrowing supports immediate protection/urgency (e.g., avoiding errors).
1 mark: Identifies gratitude as a positive emotion.
1 mark: Explains positive emotions broaden awareness (more ideas/options for improvement).
1 mark: Links broadening to building resources (e.g., skills, confidence, social support) over time.
