How much can dogs and cats remember?
Cats and pet dogs can remember the location of their food dishes, sometimes even how to perform tricks or find their way home. But, how good (or bad) are these reminder balls entering in the details of his days?
, And conversational development, experts said Life Science depends on the usefulness of those memories for them.
Take stray dogs, for example. "About 75 percent of dogs in the world are neither pets nor living in human homes," said Monique O'Dell, assistant professor of animal science and pastures at the University of Oregon. Udell said a memory that helps dogs excel in cleaning can help them survive on the streets. [20 strange cat and dog behaviors explained science]
For example, understanding the basic scrolling tasks, knowing that something is still there, although not visible - can help the scavengers.
"If someone walks in the trash and throw a hamburger, I may not see her again, but [dogs] can remember that there is a hamburger and can look [on it] the last place I saw," Udell said.
When foods are concerned, dogs can have excellent working memories - a kind of mental ray board where memories are still short term. Udell said in addition, dogs used long-term memories to help them remember tricks like rolling orders. It is possible that over time, dogs who forged close relationships with humans (ie, respond to your vocal commands) then benefited and lived to pass their genes, reported Life Science earlier.
Dogs can also have episodic memories. These are as long-term memories, but are more complex because they require self-awareness. (It is unclear whether dogs recognize themselves, so for them, these memories are called "episodic memories"). Occasional memories are often biographical and relate to "what", "when," and "where" details Udell.
Some dogs showed episodic memories in the 2016 study published in the current journal Biology. Seventeen dogs were taught to imitate humans in the "do as I do" model, then lie down. For example, if a human hit a bottle, so that the dog before bed.
After one of these tasks, after placing the dog down, the man completed additional procedures, such as playing an umbrella, giving a well-known order. Then the man took the dog behind the veil, and waited for 1 minute to 1 hour before asking the dog to "do it".
The
researchers found that some dogs are able to remember and make
tradition at every point in time, although most dogs decreased
performance over time between seeing work and asking to do so. The researchers said the results suggest that dogs can encode memories
with unrelated commands, and then can be combined with subsequent
commands, as long as the order is given in about an hour.
"Dogs can keep things in memory for a long time," Udell said. "But what you remember and how long you can remember has much to do with the context." For example, if the owners leave for military service, dogs can remember years later, suggesting that dog owner links are important for them.
But if you ask, "Where is the ball?" I can forget in a few minutes.
Udell said "it has to do with the context, significance and significance of things that were encrypted." [Are dogs smarter than cats?]Memories of freaks
Cats, like dogs, excel in remembering the details related to their evolutionary history. Mekel Delgado, a doctoral candidate in psychology at the University of California, Berkeley, who is also the testimony of cat behavior consultant for example, said cats seem to have good memories when it comes to hunting.
In two experiments, nearly 50 cats were able to remember what foods containing food, even after taking cats out of the room for 15 minutes, according to a January study of daily behavioral processes. These findings suggest that cats have a short term that can encode the details of "where" and "why" for short periods of time, at least when it comes to working food memories.
Another study, published in 2008 in the journal Animal Behavioral Sciences showed that cats are also good with spatial memory. In this study, cats were to remember what a cup had already eaten on a plate containing several half-cup hidden. The researchers said however, older cats made more mistakes than younger ones, suggesting that cats' memory declines with age.
This type of memory can help cats to remember where prey is found, and if they have patrols especially in that night, Delgado, who did not participate in the study.
However, memories of working cats can be surprisingly short-lived, especially when those memories do not involve food. In a 2006 study published in the Animal Perception Journal, 24 cats watched an experimenter hide an object in one of four boxes. Cats were waiting for 0, 10, 30 or 60 seconds before allowing them to find the object.
