The brain is a complex system, and humans are constantly exposed to different things and experiences that need to be retained. But how does it choose which memories to retain and how does it retain in the first place?
Adaptive Memory: The Comparative Value of Survival Processing (Nairne, Pandeirada, Thompson)
The human brain is often biased towards different subjects. The limbic system is the beginning of the memorization process, and it allows for both memorization and learning. (Cretu, Simona-Mariana, 2013) The first experiment was used to observe survival-based processing by putting test subjects through 5 different scenarios. (Nairne, J. S., Pandeirada, J. S., & Thompson, S. R., 2008) The human mind often retain things regarding survival. When put into a survival based scenario, things such as food-objects and objects needed to survive were much more retainable then personal experiences and pleasantness. The survival scenario was where one must survive in a stranded grassland in a foreign land. The test subjects were given a list of words, and was asked to rate the words by relevancy to the situation on a scale of 1(totally irrelevant) to 5(extremely relevant). The second task was to rate the pleasantness of each word based on the scale of 1 (totally unpleasant) to 5 (extremely pleasant). The third task focused on imagery. The test subject was asked to rate a list of words based on the difficulty of recalling mental images on a scale of 1(low imagery) to 5 (high…
