Abstract
The aims of this chapter is to offer education professionals an assessment proposal that will help them to know the motor skills of children from 3 to 5 years old. The authors also propose to offer a methodological alternative for the creation of psychomotor intervention plans. Committed to the importance of psychomotor development for the global development of the human being, they offer an evaluation proposal using the McCarthy Aptitude and Psychomotor Skills (7th edition) as a tool. This work begins by making a chronological review of the concept of psychomotor skill and its importance in child development. It is supported by the evolutionary, psychopedagogical, psychoanalytic, and neuropsychiatric theories that have shown this aspect throughout the times, and highlighting the aptitudes and stages of motor development that children under 3, 4, and 5 years old must reach. The authors hope to provide practical knowledge that will contribute to the optimization of educational work and benefiting children´s development.

Investigating the Importance of Website Color Contrast in E- and M-Commerce
Contrast is the difference in luminance and/or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or from place to place. The maximum contrast of an image is the contrast ratio or dynamic range. Finally, contrast is the perceived difference in colors that are in close proximity to each other. Using contrast effectively not only differentiates a design from others, it is the essential ingredient that makes content accessible to every viewer.
