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.

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.
The researchers were uncertain, however, if the honey bees have a sense of time governed by their circadian rhythm by connecting a specific memory to a certain time period in the 24-hour cycle, or if they can measure elapsed time between two events. The difference in this type of memory from other episodic-like memory in animals is the presence ...
To improve the reliability of individual response times, researchers typically require a subject to perform multiple trials, from which a measure of the 'typical' or baseline response time can be calculated. Taking the mean of the raw response time is rarely an effective method of characterizing the typical response time, and alternative ...
Studies with captive birds have given insight into which birds are the most intelligent. While parrots have the distinction of being able to mimic human speech, studies with the grey parrot have shown that some are able to associate words with their meanings and form simple sentences (see Alex). Parrots and the corvid family of crows, ravens ...
Disney's new short film "Reflect" features a plus-size dancer who is uncomfortable with her reflection. Anne Poirier is a body image coach. Historically, Disney's heroines and princesses tend to ...
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 ...
