Development of mental transformation abilities

Running head: DEVELOPMENT OF MENTAL TRANSFORMATION ABILITIES 1 Development of Mental Transformation Abilities

Mental representation and transformation of spatial information is often examined with mental rotation tasks, which require deciding whether a rotated image is the same or the mirror version of an upright image. Recent research with infants shows early discrimination of objects from mirror image versions. However, even at age 4, many children perform near chance level on more standard measures....

compactifications and representations of transformation semigroups

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

Decomposing the relationship between mental speed and mental abilities

Article history: Received 11 October 2013 Received in revised form 27 January 2015 Accepted 1 May 2015 Available online xxxx It is unclear whether different elementary cognitive tasks (ECTs) are associated with intelligence because these tasks tap the same basic cognitive process (suggesting a single mental speed factor) or different ones (suggesting several mental speed factors), as it is not ...
