Do you remember what did you have for dinner last weekend This ability is a function of episodic memory, and we remember that the time and place of specific events decrease with age. The squid also seems to have some episodic memory, but unlike humans, the ability does not diminish with age. new paper published in Royal Society Procedure B.
“Sepia can be remembered for what to eat, where and when, and can be used to guide future feeding decisions,” said Cambridge University author Alexandra Schnell, who has conducted experiments at the Marine Biology Laboratory in Woods Hole, Massachusetts. “It’s amazing not to lose that ability with age, despite showing signs of aging such as muscle function and loss of appetite.”
At the beginning of the year, we complained In a study by Schnel and other colleagues showing that squid can delay joy. Specifically, they could pass the cephalopod version of the famous Stanford marshmallow test: instead of settling for a prey that is no more desirable than waiting for the prey they prefer. Sepia also performed better in a subsequent study test – this link between self-control and intelligence was first found in a non-mammalian species.
In these experiments, squid had to choose between two different prey: eating raw prawns immediately or preferring to improve shrimp with live grass. The subject could see two options for the duration of the rehearsal, and stop waiting at any time and eat prawns if he is tired of having grass shrimp.
The team did a study work on the squid to assess cognitive performance. Cephalopods first learned to associate a visual symbol with a specific prey prize, and then the researchers reversed the situation so that the same prize could be associated with different symbols. They found that squid waited for a better reward and accepted a delay of 50 to 130 seconds, comparable to that of high-brained vertebrates such as chimpanzees, crows, and parrots.
In this final study, we examine whether the squid has an episodic memory: the ability to remember the context of a single past event, where it occurred, and when it occurred. Humans develop this ability around the age of 4, and our episodic memory decreases as we age. This is our ability to remember the general knowledge we have learned without the context of space and time compared to semantic memory. It has been shown that human semantic learning continues to do so as it progresses.
The hippocampal region of the human brain is of great importance in episodic memory, and it is thought that deterioration over time is responsible for the decline in our episodic memory as we age. For a long time, scientists assumed that episodic memory was human because this way of retrieving memory is associated with the conscious experience of memory. Humans can express these aspects orally; it is much more difficult to assess the possible conscious experience of animals without words (in human terms).
However, while several animal species have been shown to exhibit “episodic-looking” memory abilities, the term used by scientists in this subfield is “explicitly recognizing that we are not taking into account human characteristics of language and self-projection,” Schnell et al. he wrote in a footnote. For example, A 1998 study they found that jay birds could remember when and where they stored fodder food and what the food was. Behaviors that are indicative of memory like the episodic in the year have also been seen magic, big monkeys, rats, and zebrafish.
Similar memory evidence is also shown in the section squid. The squid lacks a hippocampus, but it has distinctive brain structures and arrangements, with a vertical lobe that shows similarities to the connectivity and function of the human hippocampus — learning and memory. Past research has shown that squid are future-oriented and can optimize foraging behavior and remember the details of responding to changes in prey conditions that fit their strategy — what, where, and when — past memory traits such as episodic.
