Cognitive science has identified at least four key factors that can be described as "pillars of learning", since they play a decisive role in the speed and ease of all school learning: attention; active engagement of the child; rapid feedback of information; and daily consolidation of learning.

Let's start with attention, which can be defined as the set of mechanisms by which the brain selects information and directs its processing. American psychologist Michael Posner distinguishes at least three attentional systems: alertness, which globally modulates the level of vigilance; attentional orientation, which selects an object; and executive control, which selects the appropriate processing chain for a given task and controls its execution. Each of these systems massively modulates brain activity and can therefore facilitate learning, but also steer it in the wrong direction. A teacher's greatest skill is undoubtedly to channel and captivate the child's attention at all times, in order to direct it to the appropriate level.

The brain'salertness and vigilance systems signal when it's time to pay attention. They are accompanied by the massive, diffuse release of neuromodulators such as serotonin and acetylcholine. These modulate cortical activity and learning on a massive scale. Animal experiments show that their discharge can radically alter the plasticity of auditory or tactile cortical maps. Daphné Bavelier's work suggests that video games provide a particularly effective means of mobilizing these systems.
