Limitations on Processing
Resource-limited processes
- Applying more effort or processing resources increases task performance
- If output not available until task is finished, then devoting more resources decreases RT
- If output continuously available, then performance increases
Data-limited processes
- Processes dependent upon the quality of data input, rather than upon resource allocation
- Relevant to degraded stimulus tasks
- Relevant to perception-attention interface
Most processes have both resource- and data-limited components
