Development of our Executive Functions

Executive functions develop gradually and slowly from birth to the end of adolescence or early adulthood.

If the first manifestations of executive functions are visible from the first year of life, the process of maturation is slow and the development of these abilities also involves learning. It is therefore normal for children to have difficulty in controlling themselves, to focus their attention for a certain time, to adapt to changes, to stop an activity to start a different type of activity, to follow rules, to manage complex tasks, to give up immediate gratification …

The progressive development of executive functions explains that one or more EF deficiencies exist during childhood and persists partly in adolescents. The development of executive functions is rapid during the preschool years and accelerates again in adolescence. It must be emphasized that individual variations are common.

  • At 3 years, children are able to perform tasks that have two different rules (for example: if you see a red apple on the screen, press such button, if you see a green apple, press another button). They are able to focus their attention on one of the two rules the time necessary to reach the goal and to inhibit the other rule, the two instructions being maintained in the short-term memory.
  • While it is difficult for 3-years-old to consider several representations of the same object, from 4 years old, children can recognize an object for what it is and its resemblance to another (it is a sponge, it looks like a pebble).
  • After the age of 3, the efficiency of the inhibitory control increases, the child gradually becomes able to defer a reward to obtain a greater one. He controls his desires and emotions.
  • At age 5, the child can inhibit one rule to activate another even when it concerns two characteristics of the same object (if the red object is round, press a button, if the red object is square, press a other button). He can successfully resolve a conflict and inhibit an action that has become routine (after pressing a button several times for the red object, it must change the button if the object is also square). As memory develops, the child remembers the places and objects he has already explored, and he can think of different strategies and imagine alternatives.
  • The executive functions of 7 years old children approach those of adults, if we stick to what can be visualized in brain imaging, ie concerning the development of neural connections involved in executive control. Children of this age can focus their attention on a task. The self-regulatory capacity continues to develop between 10 years old until the end of adolescence.

The development of executive control also implies a diversification of the processes involved, a specialization (the child is gradually able to remain focused on a goal and choose the behaviors best adapted to a situation) and a control more and more self-directed ( it depends less and less on the adult and the context to self-regulate) and anticipated (he is capable of more planning).
