The theory is considered  constructivist  , meaning that , unlike nativist theories ( which describe cognitive development as the unfolding of innate knowledge and abilities ) or empiricist theories ( which describe cognitive development as the gradual acquisition of knowledge through experience ) , it asserts that we construct our cognitive ...
Introduction. The population frequency of a bicuspid aortic valve is â0.9% to 1.36%, 1â3 with a 2:1 male:female ratio. It is likely that the presence of a bicuspid aortic valve has a genetic basis, with the pattern of transmission in some families suggesting an autosomal dominant pattern of inheritance.
The bicuspid, or mitral valve (also called the left atrioventricular valve), is located between the left atrium and left ventricle.It prevents any backward flow of blood duri â¦ ng contractions of the left ventricle.4 people found this useful.Don Dfoofnik.he bicuspid (or mitral) valves each have two large flaps, curved to close the rear entrance of a chamber, through which blood enter â¦ s. The tricuspid valve is located between the right atrium and the right ventricle. It normally has three flaps but may have two or even four flaps, and this can change with age.
