Answer:
retrograde amnesia
Step-by-step explanation:
Memory can be defined as the ability of an individual to assimilate information, store this information and recall or retrieve it later in the future.
Generally, there are basically three (3) processes associated with memory and these include;
1. Encoding of data: it involves the process of getting data (informations) into our memory.
2. Storage of data: it simply involves the process of storing and maintaining data (informations) in our memory.
3. Retrieval of data: it involves the process of getting or retrieving data (informations) out of our memory.
According to cognitive psychologists, the process of retrieving or getting data out of our memory can fail or be successful depending on a number of factors such as situation, condition, or context.
An encoding specificity principle states that an individual's memory is enhanced and improved when data (informations) made available during the process of encoding is also available at retrieval (decoding).
Amnesia can be defined as a form of memory loss that affects the ability of an individual to make, store, and retrieve memories.
There are three (3) main types of amnesia and these include;
I. Anterograde amnesia.
II. Global amnesia.
III. Retrograde amnesia
Retrograde amnesia is a term used by psychologists to describe the difficulty an individual faces in retrieving or recalling past personal history memories or past factual memories. Thus, an individual that has retrograde amnesia looses previously existing memories and it could be caused by dementia, traumatic injury, stroke, seizure, etc.
