Psychologists investigating theoretical and computer models of human cognitive processing study how information is encoded, stored, and retrieved. They ask participants to complete a complex sorting task under different conditions and then ask them about their experience afterwards. Typical participant responses include:

• Response A: 'I felt there was a bottleneck and I couldn't pay attention to both the auditory and visual signals at the exact same time.'
• Response B: 'I had to store the visual details in my head first, then compare them to the rules, and finally decide which category they belonged to.'

Briefly suggest how each of these responses might inform psychologists investigating models of human cognitive processing.
