Document Summary
Errors can also occur due as a result of feelings of familiarity (e. g. as often occurs with source monitoring errors) Results of ross et al. (1994) suggest rates of false positives may be higher if lineups are produced that do not contain a perpetrator. Suggestive questioning (e. g. misinformation effect) or confirming feedback (post- identification feedback effect) can increase the probability of errors. Wells & bradfield (1998) showed feedback affects confidence this may also make memories easier to retrieve, acting as another mechanism that can make errors more likely: march. Liu et al. (2012): used optogenetic reactivation of hippocampal neurons" to activate a fear-based memory. Delivered foot shocks to establish fear memory, located neutrons associated with that memory in the hippocampus. Genetically engineered those cells to respond to pulses of light, essentially allowing them to be turned on/off" inferred retrieval of memory based on freezing behavior.
