In cases where individuals are fearful of their thoughts (e.g., people with obsessive-compulsive disorder who experience aggressive obsessions; people with post-traumatic stress disorder who constantly try to rid themselves of their traumatic memories), exposure to the feared thoughts and memories can be useful.
Another study might try to minimize a person's biased memory of exposure by collecting actual data on phone use from phone networks (scanning phone minutes and call logs from real bills), but this would violate privacy laws.
There is convincing experimental evidence to suggest that epigenetic marks act as a memory of exposure to inappropriate environments in early life.
Others consider sensitization any immunologic memory of exposure, regardless of its pathogenic potential (i.e., a specific IgG response) (Abbas et al. 2000).
Third, when participants who had moved out of greater London between study waves were excluded, we observed associations for decline in memory with exposure 4 years preceding the second assessment.
Rat pups displayed deficits in learning and retention of memory after exposure to the organochlorine insecticide and acaricide endosulfan (6 mg/kg bw) on PND2 25 (Lakshmana and Raju 1994).
Adults were rarely infected with H1N1 regardless of HI antibody titre, possibly because of cumulated heterosubtypic immunity from recent exposures to H3N2, although older adults in the study could have been protected by H1N1 memory from exposures prior to 1957, before H1N1 was replaced by H2N2.
Furthermore, to minimize false memory of exposures, each woman was interviewed by a trained nurse actively using a detailed lifetime calendar and a list of examples of milestones.
Infants in this trial were 4 to 6 months old when enrolled, so even at this very young age, a noticeable proportion have immunological memories of exposure to at least one of these viral pathogens.
In line with this view (see for an overview [ 111]), dissociation is regarded as a coping strategy to deal with the extreme arousal elicited by recalling of trauma-related memories during exposure.
