So researchers have used proxy indicators for symbolic abilities, such as early art or sophisticated toolmaking skills.
In addition, most (but not all) of these generalist genes for learning abilities (such as reading and mathematics) will also be associated with other cognitive abilities (such as memory and spatial ability).
Evolutionary adaptations of the human brain are the basis for our unique abilities such as language.
Some argue that, in the course of over 10,000 years of domestication, dogs were selected for their cognitive abilities, such as following commands.
Moreover, perceptual experiments can be designed to ask which subdivisions of the system are responsible for particular visual abilities, such as figure/ground discrimination or perception of depth from perspective or relative movement--functions that might be difficult to deduce from single-cell response properties.
While sequential tool use has often been interpreted as evidence for advanced cognitive abilities, such as planning and analogical reasoning, the behaviour itself can be underpinned by a range of different cognitive mechanisms, which have never been explicitly examined.
Although muscle power is a prerequisite for movement, other abilities such as dynamic joint stabilization, coordination and balance, are also necessary to perform complex movements such as those in the TSP in a well controlled way.
Musicians are further noted to have enhancements for auditory-specific cognitive abilities, such as auditory working memory [17], [26], [55] [58] and auditory attention [26], which may reflect the necessary integration of auditory perceptual and cognitive skills for learning a musical instrument.
Considerable efforts have been made to develop tests for desirable non-cognitive abilities such as interpersonal and communication skills, personality and moral values [ 22, 23].
Although a nonlinear hearing instrument can compensate by increasing amplification for soft sounds, it cannot compensate for the loss of suprathreshold abilities such as impaired frequency resolution.
