The experiments show that there is close relationship between the motor ability and the operation level of visual representation,The group with high motor ability has a relatively high level in the operation of visual representation,while the group with low motor ability has a relevantly low level in the operation of visual representation.
Intuitive principle is one of the most important principles in the teaching of physical technical abilities. The direct intuitive process with the visual idea as characteristics, the indirect visual process with the auditory idea as characteristics, and the integrative physical visual experiential process are three unseparated and interactive component parts.
Its area is an abstract invariant description of the visual image.
There is reason to suppose an inverted hemispheric location of mechanisms of spatial-frequency analysis and specific description of a visual image in some subjects with the predominance of the left hemisphere.
It is assumed that the three postulated mechanisms, together with the mechanism of image recognition, create the visual image of the world perceived by the brain.
A model for visual image-background discrimination by relative movement
The aim of this study was the validation of the visual image quality of electronic portal imaging devices (EPID) and conventional verification films from the point of view of the end-viewers of portal films, the radiotherapists.
