1This morning I want to challenge an assumption most of you absorbed in your first year psychology courses.
2The traditional view holds that memories, once fully consolidated, become stable and remarkably resistant to later alteration.
3However, research on reconsolidation suggests that recalling a memory can temporarily return it to a fragile, changeable state.
4The classic experiments involved rats, though subsequent studies have replicated the basic effect in human volunteers.
5What I want to emphasize here is the therapeutic promise this carries for conditions such as post traumatic stress.
6The initial trials suggested that propranolol, given during recall, weakened the emotional intensity of traumatic memories.
7Yet larger follow up studies painted a more cautious picture, with several high profile replications failing outright.
8Critics argue the effect may reflect simple extinction rather than genuine erasure of the original memory trace.
9It was not the drug itself but the precise timing of administration that determined whether treatment succeeded.
10Let me give you a concrete example from one laboratory where recall triggered exactly ten minutes after treatment worked.
11Moving on to implications, clinicians remain divided about whether the evidence justifies routine use in therapy.
12So the field finds itself at a crossroads, genuinely promising yet still short of definitive proof.
