So I'm wondering if there are good studies of memory blocks and memory recall. For example, I will fairly often meet a person that I haven't seen for a while, and have a hard time recalling their name. I often "feel" like there is a mental "block" electically or chemically to recalling their name, and at a later time when I'm not focusing so hard, I'm able to recall their name. It happened this past week, when I saw one of our senior VPs who was visiting from Europe. When I first saw him, I was blocked on his name, and then a few minutes later when I wasn't thinking about it, I recalled his name easily. It's pretty common in the Fire Service to take a couple moments to recall a term or a name -- is there a name or a term for how blocks occur, and how best to unblock recall? Hope that makes sense. I can provide more examples if that helps.
