MRC Centre for Neuropsychiatric Genetics and Genomics (CNGG) The results are compared with similar findings from amnesic humans and their implications for theoretical accounts of the effects of hippocampal disruption are discussed. The abnormally fast forgetting by lesioned animals in DNMS-LSS seems therefore to reflect abnormal sensitivity to proactive interference. However, no impairment in DNMS-CSN was observed. In DNMS-LSS the lesioned animals were impaired, being more susceptible than controls to increases in the retention interval. Memory for the sample was assessed with retention intervals of 10, 70 and 130 s.

On DNMS-CSN the new stimulus at the retention test of each trial was one which the animals had never encountered before. On DNMS-LSS both of the stimuli for each trial were selected from a large set of junk objects that were already familiar to the subjects. Monkeys in whom the fornix had been transected and controls were tested in two versions of delayed non-matching to sample (DNMS). This ability is referred to as “flashbulb memory.” These types of memories usually involve events that are very shocking, emotional, or have serious consequences.Owen, Michael John ORCID: and Butler, S.R.ĭoes amnesia after transection of the fornix in monkeys reflect abnormal sensitivity to proactive interference?įull text not available from this repository.

Freud thought that infantįlashbulb Memories Ask your parents or grandparents where they were when they found out that John F. Psychologists have proposed several theories to explain infant amnesia. For example, why is it that we do not seem to remember much from when we were 2 or 3 years old? Although some children do form last- ing memories, most memories from early childhood seem to fade away. Infant amnesia is the relative lack of early declar- ative memories. Amnesia may also be the result of drug use or severe psychological stress. Amnesia is a loss of memory that may occur after a blow to the head or as a result of brain dam- age.

Some people also forget information due to amnesia.

Retroactive - when new memories go retro /back in time and actively interfere with old memories.

Proactive - when old memories pro ceed to actively interfere with new memories. This kind of forgetting is called repression. Retrograde - retro - old - forgetting old memories. A person may subconsciously block memories of an embar- rassing or frightening experience. According to Sigmund Freud, sometimes blocking is no accident. The information is in your memory somewhere, if only you could find it. In other cases the old data have not been lost. It may be that interference actually does erase some memories permanently.

It is important to note that proactive interference does not lead to retroactive interfer- ence the two are separate concepts. Later, you know the new information but have trouble remembering the old data (retroactive interference). At first you may have trouble remembering them because the memory of your old address and phone number gets in the way (proactive interference). You now have to remember a new address and phone number.

In retroactive interference a later memory or new information blocks you from remembering information learned earlier. In proactive interference an earlier memory blocks you from remembering related new information. This blocking is of two kinds: proactive and retroactive. Interference refers to a memory being blocked or erased by previous or subsequent memories. Rather, interference or repression causes people to lose track of them. The fact that apparently forgotten information can be recovered through meditation, hypnosis, or brain stimulation suggests that at least some memories never decay. The memories lost, however, are the most recent ones older memories seem to remain. Interference: blockage of a memory by previous or subse- quent memoriesīrain can cause loss of memory. You may experience memory failure because of decay, interference, or repression.
