[127] [128] These values are similar to the accepted variance in IQ explained by a similar single factor known as the general factor of intelligence in humans (40-50%). [129] However, results from a recent meta-analysis suggest that the average correlation between performance scores on various cognitive tasks is only 0.18. [ 130 ]
Coren's book presents a ranked list of breed intelligence, based on a survey of 208 dog obedience judges across North America. [10] When it was first published there was much media attention and commentary in terms of both pros [11] and cons. [12] Over the years, Coren's ranking of breeds and methodology have come to be accepted as a valid description of the differences among dog breeds in ...
Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins. In 2014, a study found that the long-finned pilot whale has more neocortical neurons than any other mammal, including humans, examined to date.
Cephalopod intelligence is a measure of the cognitive ability of the cephalopod class of molluscs. Intelligence is generally defined as the process of acquiring, storing, retrieving, combining, comparing, and recontextualizing information and conceptual skills. [ 2 ]
A common test of intelligence is the detour test, where a glass barrier between the bird and an item such as food is used in the setup. Most mammals discover that the objective is reached by first going away from the target.
Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.
The general factor of intelligence, or g factor, is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities. First described in humans, the g factor has since been identified in a number of nonhuman species.
In primatology, the Machiavellian intelligence or social brain hypothesis describes the capacity of primates to manuever in complex social groups. [1] [2] The first introduction of this concept came from Frans de Waal's book Chimpanzee Politics (1982). In the book de Waal notes that chimpanzees performed certain social maneuvering behaviors ...
