Default Mode Network (DMN)

A constellation of brain regions activated when a person is ostensibly relaxing or not engaged in a specific task. It's responsible for the body's interior state, self-referential thoughts, and automating behaviors.

House of Habit

A metaphor for the Default Mode Network, highlighting its function in instantiating and perpetuating our habits over time. These habits tend to be predominantly self-referential and self-evaluative.

Languishing

A state where people are just getting by, experiencing a deficit of satisfaction or engagement with what they are doing. It's often characterized by retreating, avoiding, and living lives of quiet desperation, linked to a low-grade depressive reaction.

Flourishing

A state where individuals maximize passion and engagement, pursue important values and goals, and experience a trajectory of growth. It involves enriching and expanding one's sense of self while contributing to others.

State of Sensation

A psychological state achieved by intentionally prioritizing and allocating attention to sensory input from our sense organs. This draws brain resources away from the Default Mode Network, shifting focus from stability towards change and growth.

Sense Foraging

A practice of paying attention on purpose to something sensory that one would ordinarily ignore, with the intention to find something interesting, surprising, or unusual. It's a refinement of mindfulness focusing specifically on sensation.

Active Inference

A deep-seated habit where individuals try to fix or change the world to fit their existing models, especially when confronted with negative information or discomfort. It involves resisting new sensory data that challenges internal expectations.

Radical Acceptance

A starting point that allows people to let go of expectations and explore situations from a perspective of not having an immediate answer. It involves moving into receptivity and accepting present sensations, even if they are difficult or challenging.

Toggling

The capacity to shift between two distinct modes of being: the 'house of habit' (automaticity and stability) and the 'sensory mode' (receptivity and change). Attention and intention serve as the vehicle for this transition.

?
What is the brain's Default Mode Network (DMN)?

The DMN is a group of brain regions that activate when you're not focused on a specific task, involved in managing your internal state, self-referential thoughts, and automating behaviors.

?
Why is the DMN called the 'house of habit'?

It's called the 'house of habit' because it instantiates and perpetuates our habits, especially those that are self-referential or self-evaluative, leading to automatic responses to the world.

?
Is the DMN beneficial or detrimental to well-being?

The DMN is essential for survival and efficiency, allowing us to perform routine tasks without much thought. However, if it becomes our dominant mode without other options, it can lead to unhappiness, rumination, and being stuck in unhelpful patterns.

?
What is the difference between languishing and flourishing?

Languishing describes a state of merely getting by with little satisfaction or engagement, often involving avoidance. Flourishing, in contrast, means maximizing passion and engagement, pursuing values, and experiencing personal growth and contribution.

?
How can we move from languishing to flourishing?

To move from languishing to flourishing, we must undercut the dominance of the DMN and develop the skill to toggle from automaticity to a state of exploration and sensation, allowing the world to change us.

?
What is a 'state of sensation'?

A 'state of sensation' involves intentionally prioritizing and allocating attention to sensory input, thereby drawing brain resources away from the DMN. This shift promotes change and growth over rigid stability.

?
How does sense foraging differ from mindfulness meditation?

Sense foraging offers a lower barrier to entry than formal meditation, focusing specifically on sensory elements to quiet the mind without requiring specific practices or paraphernalia. It aims to provide the sensory-saturated experiences often found in meditation without the full commitment.

?
What makes individuals vulnerable to depression?

Vulnerability to depression stems not just from negative thoughts, but from the deep-seated habit of shutting down sensation of the body and external world when negative emotions arise, creating an 'echo chamber' of thoughts without competing sensory information.

?
Why is 'chaos' considered positive in the context of sensation?

Sensation provides a 'chaotic counterbalance' to the DMN's drive for stability and certainty, allowing us to be surprised, update our models, and grow. This beneficent chaos helps prevent us from getting stuck in rigid self-concepts and negative thought loops.

?
What is 'toggling' in this context?

Toggling refers to the capacity to consciously shift between the 'house of habit' (automaticity) and the 'sensory mode' (receptivity and change). This transition is facilitated by attention and intention, allowing for enhanced awareness and adaptability.

1. Cultivate Sensory Receptivity

Intentionally shift your attention to sensory input to draw brain resources away from the default mode network, fostering change and growth over habitual stability. This naturally quiets overthinking and allows new information to update your models of the world.

2. Practice Daily Sense Foraging

Engage in ‘sense foraging’ by paying attention to sensory details you’d normally ignore, with the intention of finding something interesting, surprising, or useful. This practice helps undercut the dominance of habitual thought patterns.

3. Embrace Beneficial Chaos

For most people, introducing more ‘chaos’ (surprise, new connections, and change) through sensory exploration can balance the default mode network’s drive for certainty. This shift can lead to personal growth and a more balanced state of being.

4. Give Permission to Shift Modes

Step out of ‘doing and performing mode’ by giving yourself permission to become receptive to your surroundings, even for a few moments. Notice the subtle changes in your emotional and mental state afterward.

5. Radically Accept Sensory Input

Be willing to accept physical or sensory information as it is, even if it’s difficult or uncomfortable, rather than immediately trying to fix it. This approach helps update your internal models and reduces the struggle against reality.

6. Unplan Your Mind with Senses

Realize you have the capacity to ‘unplan’ your mind by engaging your senses, allowing you to receive new information and change from the world. This can unlock habitual thought patterns and provide moments of respite.

7. Utilize Ubiquitous Sensory Cues

Leverage the constant availability of sensory information in everyday environments, such as the colors of peppers in a grocery store or the texture of fruit. These provide easy, low-barrier opportunities for sense foraging.

8. Avoid Forcing Sensory Outcomes

Approach sense foraging without expecting specific results or immediate happiness; instead, allow yourself to fall into a receptive mode and observe what arises naturally. This prevents the practice from becoming another task.

9. Explore Sensory-Rich Environments

Seek out activities and places like nature, exercise, art, or travel, as these are ’target-rich environments’ for engaging your senses. These settings naturally foster new experiences and sensory immersion.

The DMN's mental routines evolved to help us survive long enough to reproduce, but they are agnostic when it comes to our individual well-being.

Zindal Siegel

Sensing is not thinking. Thinking is often the place where many of their problems are cooked up. And yet, sensing might be the place where change is possible.

Zindal Siegel

If our senses are where change comes from, and our thoughts are stabilizing, crystallizing forces, and all we have are the crystallizing forces and they're negative, then we've condemned ourselves.

Norman Farb

Most of us could use a little bit more chaos in our lives.

Norman Farb

Meanwhile, the world goes on. And it's like all of these gears can be rotating in your head, all of these things, loss, and I'm good, I'm no good, and you're underneath. And meanwhile, the world goes on, like all of these sensory things are going on, regardless of what you're doing in your own mind. And they're also available for you to plug into. And that sometimes can actually pull you out of that.

Zindal Siegel

It's not rocket science, but it is neuroscience.

Sense Foraging Exercise

Norman Farb
  1. Take stock of how much you actually care about what the space around you is like right now.
  2. Set an intention to give yourself permission to go out of doing and performing mode and become receptive.
  3. Take a few moments (at least 5-10 seconds) to look around the room and care about its interesting accoutrements.
  4. Come back and notice if you've noticed anything different, such as feeling more relaxed or grounded in the space.
