A5.10

Attentional capacity and bottlenecks

Cards in this group · 5

  1. A5.10.1Limited processing resources mean simultaneously presented information necessarily involves trade-offs
  2. A5.10.2Early selection theory holds that filtering happens before semantic analysis
  3. A5.10.3Late selection theory holds that all channels are processed to the semantic level, with selection happening afterward
  4. A5.10.4Capacity allocation is dynamic — a harder sub-task takes a larger share at other tasks' expense
  5. A5.10.5The bottleneck's location shifts with task type; there is no single fixed filtering stage
