Formal assessment of h. m. "s anterograde amnesia: discovery of unconscious memories. In this test of verbal long-term memory, h. m. was asked to repeat 5 digits that: h. m. was given 7 tests to assess his long-term memory. The first 2 document his severe deficits in long-term memory, whereas the last 5 indicate he was capable of storing long-term memories without conscious awareness: digit span +1 test: were read to him at 1-second intervals. At the next trial, he was presented with the same sequence of 5 digits with 1 new digit added on the end, and so on. After 25 trials, h. m. could not move past the 8-digit sequence; normal subjects can repeat about 15 digits: block-tapping memory-span test: information presented in all sensory modalities.
