The hamadryas baboon is one of many primate species that has been administered the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability of visual self-recognition. [1]
The animals are then allowed to see their reflection in a mirror; if the animal spontaneously directs grooming behaviour towards the mark, that is taken as an indication that they are aware of themselves. [66] [67] Over the past 30 years, many studies have found evidence that animals recognise themselves in mirrors. Self-awareness by this ...
Delayed response tasks are often used to study short-term memory in animals. Introduced by Hunter (1913), a typical delayed response task presents an animal with a stimulus such as colored light, and after a short time interval the animal chooses among alternatives that match the stimulus, or are related to the stimulus in some other way.
Nocturnal animals (for example, tarsiers) and animals that live in open landscapes have larger eyes. The vision of forest animals is not so sharp, and in burrowing underground species (moles, gophers, zokors), eyes are reduced to a greater extent, in some cases (marsupial moles, mole rats, blind mole), they are even covered by a skin membrane.
A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another. [1] [2] [3] Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting.
The study included an experiment in which a subordinate animal was allowed to choose between food that a dominant animal could also see and food that it could not; those who were subject to aggressive behaviour selected the food that the dominant animal could not see, suggesting that they are able to perceive a threat based on being within the ...

The eyes of an animal with monocular vision are positioned on opposite sides of the animal's head, giving it the ability to see two objects at once. This is usually most commonly seen with prey animals, as the reason why their eyes are placed on either side of their head is to make it easier for them to look out for predators, which usually ...
