Clive Wearing

Demonstrates that memory is crucial to our well being and everyday functioning

Was left with extensive brain damage, which caused major memory disruption

He is still able to talk, read and write, however his memory is dramatically impaired

The fact Clive continues to talk, walk, play music, read and write, in spite of huge impairments in his memory for personal history and general knowledge suggests that memory is not a unitary system

Clives case raises a number of questionsfor cognitive psychologists e.g. why do you think Clive cannot recall a visit from his wife a few minutes earlier? One possiblility is that her visit never actually registered in his mind so no memory trace was laid down, another is memory trace was laid down but faded quickly, another is the memory trace was laid down but faded quickly, another is the memory trace was laid down but cannot be recived
