What are executive functions?
Executive functions are a family of top-down[1] mental processes that make possible mentally playing with ideas; approaching unanticipated challenges with flexibility; taking the time to think before acting; resisting temptations, and staying focused[2].
Executive functions are interrelated, and they depend on a neural circuit in which the prefrontal cortex at the front of the brain plays a prominent role. The core executive functions include[3].
- Inhibitory and interference control – self-control, selective attention, cognitive inhibition, resisting temptations and resisting acting impulsively
- Working memory – Our mental workspace that controls our ability to retain and manipulate pieces of information over short periods of time
- Cognitive flexibility – thinking “outside the box”, seeing things from different perspectives, and quickly and flexibly adapting to changed circumstances.
Individuals are not born with all of these skills; rather they develop over a person’s life on average reaching full maturity in their mid-twenties. The development of executive skills is crucial for learning, development, positive behaviour and good decision making[4]. They are foundational skills for later life and work.
Individuals who have executive function challenges might find everyday tasks challenging such as:
- Keeping track of time
- Conceptualising how long a task will take
- Making plans
- Getting started on a task
- Staying focused during a task
