What are executive functions anyway?

Have you heard of the term "executive function"? It's been quite the buzzword lately. Technically, we use this term when someone is having a tough time keeping up with school, work, or social demands. The interesting thing is that executive function plays a role in almost everything we do and is a major driving force behind our learning process.

So, what exactly is executive function?

‍

Well, it's a set of cognitive processes that help us navigate through life. Imagine your brain as a bustling workplace, a grand symphony, or a dynamic sports team. At the helm is the executive function, acting as the boss, the conductor, or the coach. It orchestrates tasks, manages priorities, and ensures everything runs smoothly. Some researchers even call it our "brain steering skills," which is a pretty good way to look at it. It involves setting goals, figuring out how to achieve them, and putting our plans into action. Along the way, we make adjustments and improvements, until eventually, what we're learning becomes second nature and requires less mental effort (that's when we've mastered it!). Sounds simple, right? But in reality, these processes are quite complex, with many different moving parts.

To get a better understanding, let's break down the specific skills that fall under the umbrella of executive function.George McCloskey is a prominent researcher and pioneer in this field. His model of executive functions breaks down executive functioning into seven clusters, encompassing 33 distinct self-regulation capacities.

The Seven Clusters of Executive Functions

1. Attention
  - Perceive: The ability to notice and register information from the environment.
  - Focus: Concentrating on relevant stimuli while ignoring distractions.
  - Sustain: Maintaining attention over prolonged periods to complete tasks.

2. Engagement
  - Energize: The drive and motivation to start activities.
  - Initiate: The capacity to begin tasks or projects independently.
  - Inhibit: Restraining impulses and resisting distractions.
  - Stop: The ability to cease an action or thought when necessary.
  - Interrupt: Temporarily halting one task to attend to another, then resuming the original task.
  - Flexible: Adapting to new information or changing conditions.
  - Shift: Moving smoothly from one activity or thought to another.

3. Optimization
  - Monitor: Keeping track of progress and performance.
  - Modulate: Adjusting actions and emotions to suit the situation.
  - Correct: Making adjustments to correct errors or improve outcomes.
  - Balance: Managing competing demands and resources.

4. Efficiency
  - Sense Time: Being aware of time and its passage.
  - Execute Routines: Performing habitual tasks efficiently.
  - Sequence: Organizing steps in the correct order.
  - Pace: Regulating the speed of work to ensure timely completion.

5. Memory
  - Hold: Retaining information in mind temporarily (working memory).
  - Manipulate: Working with information held in memory.
  - Store: Committing information to long-term memory.
  - Retrieve: Accessing stored information when needed.

6. Inquiry
  - Gauge: Assessing situations accurately.
  - Anticipate: Predicting future events or outcomes.
  - Estimate Time: Judging the amount of time needed for tasks.
  - Analyze: Breaking down information into parts to understand it better.
  - Compare/Evaluate: Assessing options or outcomes to make informed decisions.

7. Solution

- Generate: Coming up with new ideas or solutions.

- Associate: Connecting related pieces of information.

- Plan: Developing steps to achieve a goal.

- Organize: Arranging resources and tasks systematically.

- Prioritize: Determining the order of importance for tasks.

- Decide: Making choices among alternatives.

This was a lot. So, to summarize: these clusters encompass various executive capacities involved in self-regulation. Each cluster plays a vital role in directing an individual's perceptions, thoughts, emotions, and actions toward achieving goals. For example:

- Attention: Abilities to perceive, focus, and sustain engagement.
- Engagement: Skills like initiating, inhibiting, interrupting routines, and cognitive flexibility.
- Optimization: Functions for monitoring, modulating, correcting, and balancing performance.
- Efficiency: Abilities related to time management, executing routines, sequencing, and pacing.
- Memory: Capacities to hold, manipulate, store, and retrieve information.
- Inquiry: Skills for gauging, anticipating, estimating time, analyzing, and evaluating.
- Solution: Abilities to generate ideas, make associations, plan, organize, prioritize, and decide.

McCloskey's model proposes that these distinct but coordinated executive capacities direct an individual's perceptions, thoughts, emotions, and actions in a goal-directed manner. Assessing these capacities helps identify strengths and weaknesses, guiding interventions for those with executive dysfunction. Understanding and improving executive functions can enhance our ability to manage life's demands effectively, much like a boss leading a team, a conductor guiding an orchestra, or a coach directing players on the field.
