The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
Human Cognitive Abilities: A Survey of Factor-Analytic Studies is a 1993 book by psychologist John B. Carroll. It provides an overview of psychometric research using factor analysis to study human intelligence. It has proven highly influential in subsequent intelligence research; in 2009, Kevin McGrew described it as a "seminal treatise". The ...
Human tests of cognitive ability measure a wide spectrum of mental abilities. When considering tests of cognitive ability, it is paramount to consider evidence for their reliability, validity, length, and mode of administration (e.g., some assessments require a trained administrator to be present with the respondent).
The study of memory incorporates research methodologies from neuropsychology, human development and animal testing using a wide range of species. The complex phenomenon of memory is explored by combining evidence from many areas of research. New technologies, experimental methods and animal experimentation have led to an increased understanding ...
He has stated that "It is tempting to interpret this association in the context of human cognitive evolution and species differences in brain size and cognitive ability, we show that it is not warranted to interpret brain size as an isomorphic proxy of human intelligence differences". [22]
The factors considered important to the relationship between brain size and intelligence were age, sex and hemispheric functional lateralization. They found that general verbal ability was correlated with cerebral volume in women and right-handed men. It was not possible to find a relationship between ability and volume in with every group ...
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. Using their intelligence , humans are able to learn , form concepts , understand , and apply logic and reason .
The three-stratum theory is a theory of cognitive ability proposed by the American psychologist John Carroll in 1993. [ 1 ] [ 2 ] It is based on a factor-analytic study of the correlation of individual-difference variables from data such as psychological tests, school marks and competence ratings from more than 460 datasets.
