Let’s suppose: 1. Oscar wants to go to the airport ( x ) to meet John, for which he needs to take a bus A11 ( a ) 2. On way to the bus stop, he changes his mind and informs John that he would meet him at Plus centre ( y ), and intends now to take bus C98 to go there ( b) 3. He gets busy talking chatting with someone else. 4. When he reaches the stop, he sees bus A11 ( a ) and immediately gets into it with the intention of reaching Plus centre ( y) asap. 5. Only after a while does he realize that he has got into the wrong bus. Observation: While his brain got busy in chatting, items ( x ) and ( b ) got dropped from short-term memory. On seeing the bus A11 ( a ), his brain immediately connected a with y . In fact, it seems the internal meaning of b was taken over by a for a moment. This is a problem. At that moment of memory error, belief towards action was tampered by a memory fault. See Also: Volitional Memory Error
