- Lavie (1995) found evidence for both early and late selection, and said that we have a limited attentional capacity, so attention must be split between tasks and distractions.
- High cognitive load tasks require all cognitive resources to be allocated to a difficult task and this results in early processing and selection (Filter Theory)
- Low cognitive load tasks. In these tasks, remaining cognitive resources are automatically allocated to irrelevant stimuli. This involves late processing and selection, and therefore distractors are attended more than in the high load tasks.
