OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Rewrite or repress? Parsing the mechanisms of retrieval-extinction
Please get in touch with Joao Lima (joao.lima@psy.ox.ac.uk) if you'd like to join us for dinner or just chat to Amy in the afternoon.
It has been widely reported – if not universally replicated – that presenting a reminder of a previously trained cue-drug or cue-fear memory before extinction training can lead to a long-term reduction in subsequent responding for the cue, that goes beyond the reduction in responding observed with extinction training alone. This ‘retrieval-extinction’ phenomenon has been hypothesised to depend upon memory reconsolidation; namely, that the cue-drug or cue-fear memory becomes unstable during the reminder session, and is overwritten by the subsequent extinction training. An alternative explanation is that retrieval-extinction leads to an enhancement of extinction. Here, I will present our recent research addressing whether retrieval-extinction is a reconsolidation-based or extinction-based phenomenon.
