- Slips: …result from automatic behavior, when subconscious actions that are intended to satisfy our goals get waylaid en route.
- Mistakes: …result from conscious deliberations
Types of slips:
- Capture errors
- Description errors
- Data-driven errors
- Associative activation errors
- Loss-of-activation errors
- Mode errors
Data-Driven Errors - Automatic actions are data-driven, triggered by the arrival of the sensory data. But sometimes data-driven activities can intrude into an ongoing action sequence, causing behavior that was not intended. For example, while checking into a hotel, the clerk took a phone call from another guest who was calling for a wake-up call. The clerk then got off the phone and informed me that I would be in room 630. I mentioned to him, that earlier he said I would be on the first floor. He then confessed that he just took a call to wake a guest at 6:30 and had confused it with my room number. I would be in room 110.
