Physiological Changes In Memory

The information we gathered yesterday, those we are gathering today, and those we look forward to gathering tomorrow are all part of our memory. Our memory is so vital in recalling events in our lives that if it is lost, we would not be able to effectively function; in order words, it allows us to have continuity in our lives. According to McLeod (2007), “Memory is the term given to the structures and processes involved in the storage and subsequent retrieval of information.” (p. 1). Therefore, there are certain important stages of information processing that ensure that the information received is retained in our memory; they include encoding, storage and retrieval.

Encoding is the conversion of information from our sensory receptors, by

Also, the decline of hormones and proteins that protect and repair brain cells and stimulate neural growth and the decrease of the blood flow to the brain, can impair memory and lead to changes in cognitive skills”. (p. 1).

As a result of the physiological changes in the brain, my interviewee was unable to retrieve the information as quickly as she would have done before.

My interviewee Mary Edwards, is a 76 year old resident from the Grand Roy Community. Her memories for non-personal recent events were a bit dull, in that she was unable to remember the first and last song that was sung last Sunday at the church she normally attends. This was confusing to me, because they usually sing the same opening and closing songs every Sunday. However, she was able to highlight things that were happening locally and internationally in the news. This indicates that as people age they often have memory lapses where they remember certain things better than other things. In most instances, her memories for personal recent events was very sharp. She was able to remember what she had for breakfast and the recent passing of her dear

The things that occurred in her past might have been actively experienced and as a result it stayed with her. Also, I believe she might have formed an association with the events, especially those that are personal, and it could be the reason for such a quicker and better recall. In addition, she might have told these stories over and over, that it now remains in her long-term memory. Notwithstanding, the foods she ate before might have also contributed to her memory recall.

Her personal reactions to these events were amazing. She was smiling throughout the interview. Also, the environment in which the interview was conducted served as a cue to her recalls which assisted her in retrieving the information. In addition, many older persons always seem to enjoy the company of the younger generation; the possibility exists that it reminds them of their past as children. Another reason could be the handing down of the “pros and cons” of life. Finally, our memory is so important that we should seek every opportunity to preserve
