Animal cognition

Animal cognition
Animal cognition is the study of the mental capacities of animals. It has developed out of comparative psychology, including the study of animal conditioning and learning, but has also been strongly influenced by research in ethology, behavioral ecology, and evolutionary psychology. The alternative name cognitive ethology is therefore sometimes used; much of what used to be considered under the title of animal intelligence is now thought of under this heading.[1] Research has examined animal cognition in mammals (especially primates, cetaceans, elephants, dogs, cats, horses,[2][3] raccoons and rodents), birds (including parrots, corvids and pigeons), reptiles (lizards and snakes), fish and invertebrates (including cephalopods, spiders and insects).[1] Historical background[edit] Animal cognition from anecdote to laboratory[edit] The behavioristic half-century[edit] The work of Thorndike, Pavlov and a little later of the outspoken behaviorist John B.

Primate cognition Origin of man now proved. Metaphysic must flourish. He who understands baboon would do more towards metaphysics than Locke. Primate cognition is the study of the intellectual and behavioral skills of non-human primates, particularly in the fields of psychology, behavioral biology, primatology, and anthropology.[1] Primates are capable of high levels of cognition; some make tools and use them to acquire foods and for social displays;[2][3] some have sophisticated hunting strategies requiring cooperation, influence and rank;[4] they are status conscious, manipulative and capable of deception;[5] they can recognise kin and conspecifics;[6][7] they can learn to use symbols and understand aspects of human language including some relational syntax, concepts of number and numerical sequence.[8][9][10] Studies in primate cognition[edit] Theory of mind[edit] There has been some controversy over the interpretation of evidence purporting to show theory of mind ability—or inability—in animals.

Video shows tool use by a fish The first video of tool use by a fish has been published in the journal Coral Reefs by Giacomo Bernardi, professor of ecology and evolutionary biology at the University of California, Santa Cruz. In the video, an orange-dotted tuskfish digs a clam out of the sand, carries it over to a rock, and repeatedly throws the clam against the rock to crush it. Bernardi shot the video in Palau in 2009. "What the movie shows is very interesting. The animal excavates sand to get the shell out, then swims for a long time to find an appropriate area where it can crack the shell," Bernardi said. The actions recorded in the video are remarkably similar to previous reports of tool use by fish. "Wrasses are very inquisitive animals," Bernardi said. Wrasses are one of the largest and most diverse families of marine fishes. Tool use was once considered an exclusively human trait, and Jane Goodall's reports of tool use in chimpanzees in the 1960s came as a stunning revelation.

Top 10 Common Faults In Human Thought Humans The human mind is a wonderful thing. Cognition, the act or process of thinking, enables us to process vast amounts of information quickly. For example, every time your eyes are open, you brain is constantly being bombarded with stimuli. You may be consciously thinking about one specific thing, but you brain is processing thousands of subconscious ideas. Unfortunately, our cognition is not perfect, and there are certain judgment errors that we are prone to making, known in the field of psychology as cognitive biases. The Gambler’s fallacy is the tendency to think that future probabilities are altered by past events, when in reality, they are not. Reactivity is the tendency of people to act or appear differently when they know that they are being observed. Pareidolia is when random images or sounds are perceived as significant. Interesting Fact: the Rorschach Inkblot test was developed to use pareidolia to tap into people’s mental states. Self-fulfilling Prophecy

Elephant cognition Elephants are amongst the world's most intelligent species. With a mass of just over 5 kg (11 lb), elephant brains are larger than those of any other land animal, and although the largest whales have body masses twenty-fold those of a typical elephant, whale brains are barely twice the mass of an elephant's brain. In addition, elephants have a total of 257 billion neurons. [1] The elephant's brain is similar to that of humans in terms of structure and complexity—such as the elephant's cortex having as many neurons as a human brain,[2] suggesting convergent evolution.[3] Brain structure[edit] Cerebral cortex[edit] The elephant (both Asian and African) has a very large and highly complex neocortex, a trait also shared by humans, apes and certain dolphin species. Asian elephants have the greatest volume of cerebral cortex available for cognitive processing of all existing land animals. Other features of the brain[edit] Brain size at birth relative to adult brain size[edit] Spindle neurons[edit]

PBS Airdate: February 9, 2011 NEIL DEGRASSE TYSON (Astrophysicist, American Museum of Natural History): Hi, I'm Neil deGrasse Tyson, your host of NOVA ScienceNOW, where this season we're asking six big questions. On this episode: How Smart Are Animals? Meet Chaser. She knows the name of every single one of these? And it's not just her. Look at that intensity. And researchers are finally taking notice. BRIAN HARE (Duke University): A dog is like a soldier of science. NEIL DEGRASSE TYSON: Find Crawdad. BRIAN HARE: If we can figure out how they think, then we'll understand ourselves. NEIL DEGRASSE TYSON: Excellent, excellent, good job! And a trip to paradise, where some of the smartest creatures... TERI BOLTON (Roatan Institute for Marine Sciences): Come on, boy.

Experiments reveal that crabs and lobsters feel pain Lobsters and other crustaceans may feel pain. Matthew Roy; Wikipedia Every year thousands of them are boiled or torn apart while they are still alive, and now there is strong evidence to suggest that crustaceans experience pain. That was the stark message delivered by Robert Elwood, an animal behaviour researcher at Queen’s University Belfast, to the Behaviour 2013 meeting in Newcastle, UK, today. Crustaceans — crabs, prawns, lobsters and other creatures — are generally not protected by animal-welfare laws, despite huge numbers of them being caught or farmed for human consumption. The exclusion has been based on the belief that these animals cannot experience pain — generally regarded as an ‘unpleasant feeling’ — and instead only have nociception, a reflex response to move away from a noxious stimulus. Crabs shocked the second time the experiment was run were far more likely to choose the other shelter in the next trial, while crabs never left a non-shocking shelter.

What is serotonin? What does serotonin do? Serotonin (5-hydroxytryptamine, 5-HT) is a chemical found in the human body. It carries signals along and between nerves - a neurotransmitter. It is mainly found in the brain, bowels and blood platelets. Serotonin is thought to be especially active in constricting smooth muscles, transmitting impulses between nerve cells, regulating cyclic body processes and contributing to wellbeing and happiness.1 Serotonin is regarded by some researchers as a chemical that is responsible for maintaining mood balance, and that a deficit of serotonin leads to depression. The word serotonin comes from its discovery when it was isolated in 1948 by Maurice M. This Medical News Today article provides essential information on serotonin. You will also see introductions at the end of some sections to any recent developments that have been covered by MNT's news stories. Fast facts on serotonin Here are some key points about serotonin.

Dolphins 'call each other by name' 22 July 2013Last updated at 19:02 ET By Rebecca Morelle Science reporter, BBC World Service The research sheds new light on the intelligence of dolphins Scientists have found further evidence that dolphins call each other by "name". Research has revealed that the marine mammals use a unique whistle to identify each other. A team from the University of St Andrews in Scotland found that when the animals hear their own call played back to them, they respond. The study is published in the Proceedings of the National Academy of Sciences. Dr Vincent Janik, from the university's Sea Mammal Research Unit, said: "(Dolphins) live in this three-dimensional environment, offshore without any kind of landmarks and they need to stay together as a group. "These animals live in an environment where they need a very efficient system to stay in touch." Signature whistles It had been-long suspected that dolphins use distinctive whistles in much the same way that humans use names. Continue reading the main story
