We review research on the neural efficiency hypothesis of intelligence, stating that brighter
individuals display lower (more efficient) brain activation while performing cognitive tasks …

Hominid brain size increased dramatically in the face of apparently severe associated
evolutionary costs. This suggests that increasing brain size must have provided some sort of …

Amultidisciplinary collaborative study examining cognition in a large sample of twins is
outlined. A common experimental protocol and design is used in The Netherlands, Australia …

after the addition of T2. (iii) Antibody formation was only partially suppressed when secondary …

Intelligence has evolved many times independently among vertebrates. Primates, elephants
and cetaceans are assumed to be more intelligent than 'lower'mammals, the great apes and …

Intelligence is a socially and scientifically interesting topic because of its prominence in
human behavior, yet there is little clarity on how the neuroimaging and neurobiological …

The creative reuse of existing neural components may have played a significant role in the
evolutionary development of cognition. There are obvious evolutionary advantages to such …

This study reports the results of a large scale literature review of research studying the
relationship between intelligence and speed of information-processing. Data from 172 …
