Capacity Theory of Attention - Coggle Diagram
Capacity Theory
of Attention
Key Assumptions
Resources allocated based on task demands
Fixed pool of attentional resources
Task Competition
High-demand tasks use more resources
Multiple activities compete for attention
Limited capacity for mental work
Focus on attention capacity instead of bottleneck
Resource Allocation
Attention distributed across task
Depends on:
Task requirements
Importance of task
Performance Outcome
When demand > capacity → performance suffers or fails
When demand ≤ capacity → task performed well
Arousal
Too low / too high → poor performance
Arousal level controls capacity allocation
Optimal arousal → best performance
Capacity Limit
Mental “fuel” is limited
Exceeding capacity → slower processing
