Another show did their own experiment to see if elephants were indeed afraid of mice. On 20/20, the host contacted the Ringling Bros. and Barnum & Bailey Circus.The elephant trainer, Troy Metzler ...
Like Thorndike's cats and dogs, the 13 elephants that did master a black/white or large/small discrimination task did so gradually, over several sessions. The slope of the time-curve again suggested the elephants failed to understand the cause-effect relationships between lid removal and food retrieval.
The performance of dogs in these studies is superior to that of NHPs, [39] however, some have stated categorically that dogs do not possess a human-like ToM. [12] [40] Similarly, dogs preferentially use the behaviour of the human Knower to indicate the location of food. This is unrelated to the sex or age of the dog. In another study, 14 of 15 ...
Monkeys and chimpanzees do learn to do this, as do pigeons if they are given a great deal of practice with many different stimuli. However, because the sample is presented first, successful matching might mean that the animal is simply choosing the most recently seen "familiar" item rather than the conceptually "same" item.
The animal kingdom is full of creatures with excellent memories because having a good memory increases their chance of survival. Some of the animals with the best memories are dolphins that can ...
"Elephants live in a so-called 'fission-fusion' society, where they often separate and reunite, meeting after hours, days or months For elephants, like people, greetings are a complicated affair ...
A follow-up experiment involved three dogs affixed in harnesses, including one that received shocks of identical intensity and duration to the others, but the lever which would otherwise have allowed the dog a degree of control was left disconnected and didn't do anything. The first two dogs quickly recovered from the experience, but the third ...
This accounts for variation in the number of neurons in the rest of the brain, for which no link to intelligence has been established. Elephants, for example, have an exceptionally large cerebellum, while birds make do with a much smaller one. Differing methods have been used to count neurons, and these may differ in degree of reliability.
