"Dyads engaged in a tapping synchronization task under different levels of synchrony. Increases in heart rate synchronization were found with no difference across conditions. The control analysis, which assessed synchrony between randomly combined dyads of participants showed no difference from the original dyads’ synchrony"

"What do you think about the idea that the body sees #psychological #trauma in the same way it sees physical trauma?"

--------------------

The body indeed does not differentiate between psychological and physical trauma. It responds to both in similar ways, activating the same survival mechanisms and #stress responses.

This understanding is rooted in the Polyvagal Theory and #Somatic Experiencing, which highlight how the body stores and processes trauma.

1. **Polyvagal Theory**: This theory, developed by Dr. Stephen Porges, posits that our autonomic nervous system, which includes the sympathetic (fight or flight) and parasympathetic (rest and digest) systems, plays a major role in how we respond to stress and trauma. Both physical and psychological trauma can activate this system, triggering a cascade of #physiological responses.

**Somatic Experiencing**: This approach suggests that trauma is not just about the event itself, but about how our nervous system responded to it. When we're exposed to a traumatic event, our body goes into fight-flight-freeze mode. If we can't complete these survival actions, the body may hold onto this response, leading to chronic stress and trauma symptoms. This can take place whether the trauma is physical (like an accident) or psychological (like emotional abuse).

Through both of these lenses, we can see that the body does not differentiate much between psychological and physical trauma. Both can trigger our survival responses, can get held in our bodies, and can lead to similar symptoms and health issues.

Therapies such as mindfulness-based stress reduction, somatic experiencing, and trauma-informed practices can help individuals to process these traumas, release the held tension, and cultivate a greater sense of safety and well-being.

Remember the Buddha's words: "The body is the first foundation of mindfulness." This highlights the importance of the body in our overall wellbeing, including how it processes and stores trauma. #Mindfulness cultivates a non-judgmental awareness of the present moment, including bodily sensations, thoughts, and emotions. This can help us to notice and gently process the tensions held in our bodies due to trauma.

In practicing mindfulness, we may start to notice the subtle signs of stress or discomfort in our bodies, perhaps even before we're consciously aware of them. This increased awareness can support us in responding to stress in healthier ways, rather than reacting out of old, unhelpful patterns.

In conclusion, the body's response to psychological trauma is very similar to its response to physical trauma. The key is to bring mindful awareness to these bodily responses, allowing them to be processed and released. This is a journey that takes patience and kindness towards oneself, but it is a journey towards healing that is one of self-discovery and transformation.

It's a journey in which we learn to relate to our bodies with #kindness, understanding, and #compassion.

It's also a journey in which we learn to recognize and honor the wisdom of our bodies, as they carry important messages about our past experiences and current needs.

It's important to remember that #healing from trauma is not about "fixing" something that's "broken". Rather, it's about acknowledging our experiences, creating space for them in our #awareness, and learning to navigate life in a way that supports our wellbeing.

In the words of Thich Nhat Hanh, a renowned Buddhist monk and peace activist: "The seed of suffering in you may be strong, but don't wait until you have no more suffering before allowing yourself to be happy."

Healing is not just about the destination, but also about the journey.

In cultivating mindfulness and compassion, we can learn to hold our traumas, both psychological and physical, in a gentle embrace of understanding. This approach does not aim to erase or ignore the trauma, but rather to provide a space where it can be acknowledged, felt, and eventually, integrated. This process can lead to a deeper connection with ourselves and a profound sense of inner peace.

First, if we are to have a constructive conversation, you should consider what I have said, rather than only repeat your initial premise that you think science is "clueless" regarding what sentience is and is not.

I assume you agree that, for example, a table is not a sentient being? (there is a multitude of interdisciplinary scientific subjects which support that theory). If so, we can agree that science is not clueless about what sentience is - for part of that question is what sentience is not.

To quote a generally incorrect statement "sentience is not something, we can measure".

I disagree as science measures sentience both implicitly and explicitly.

Sentience is subjective. Can we measure how, for example, a clock functions? Of course, we can. That measure is quantitative. We can understand how a clock functions. The difference is, humans designed clockwork so we already understand how it functions.

If you study neuroscience, you should be aware that electrochemistry is also functional #physiological

So, there are some people who study (think about) the human nervous system and think about how and why that system evolved sentience - and they do understand how that "clock" functions to some degree (though not completely as there are unanswered questions).

The irony is, if someone is "clueless" regarding understanding consciousness, they of course will not be aware of what they have never been aware of.

As a thought experiment, imagine an Alien landed on the planet that had learned what its sentience was. If that Alien said to humanity "I understand my own sentience!". In general, humanity would think "WFT is that Alien talking about?". They could not be aware of what the Alien was talking about. Sentience is exclusive.

"Beauty [preference, taste, etc] is in the eye of the beholder" - that's partly correct - but, you may have noticed, humans don't perceive their own excrement as a delicious snack (yum!?). Humans have evolved sentience related to their ecological niche. In other words, if you study the science of evolutionary biology, you'd understand that there is a lot that science knows about what sentience is for (therefore, not for)

Whilst sentience is not binary, it's a gradient, just as there are varying levels of consciousness experienced by many organisms (e.g., animals), the same is true regarding humans. Some humans really are clueless, in regards to how consciousness is a biological functional system. But, even they will have their own ideas about consciousness - even if those ideas really don't measure anything and, well, don't generally ask anything (e.g., diety created it, and diety knows!)

So, I'd suggest that rather than "science" (which isn't an agency - it's a system) being "clueless" regarding what sentience is (or more specifically what it's for - why it evolved, why it's adaptive), many people have not put that science puzzle together, and therefore are themselves clueless regarding what sentience is.

Therefore, imprint their conscience experience on everyone else. So yea, I agree with your statement that you perceive that Sentience is so far beyond what science you have studied.

So, rather than repeat the same premise - why do you think sentience evolved? There are many scientific theories of why? Which theory do you consider has the most empirical evidence behind it?

Our study supports the central assumptions of #MST and highlights the role of allometric models to understand the #physiological responses involved in #plant #adaptation. #Allometry is more variable between genotypes than between environments. Suggesting that natural selection can lead to the genetic differentiation of plant allometries in different environments, but that environmental changes have limited effect on a genetically-determined type of allometry.

#Circadian rhythms are natural, internal #oscillations that synchronize an organism's #behaviors and #physiological processes with their #environment. These rhythms normally have a period of 24 hours and are regulated by internal #chemical clocks

@actuallyautistic @ratcatcher I agree that one has the #physiological #neurodivergence that results in expressing #autistic traits, and impacts their lives, or they do not.

I’m curious why we would be concerned at all about severity, unless it was about choosing tools to enable one to improve their ability to function in the world.

Or are we really worried whether someone is “autistic enough” to be #actuallyautistic ?? To me this seems a pointless distraction.

@JamesWafer228 @actuallyautistic That simplification leads folks to the “aren’t we all #actuallyautistic in our own way?” conclusion.. The #stigma of #autism and how it affects us is not something non-autistics will experience. What flags us as #targets for #discrimination is the very way our #physiological #neurodivergence alters our #sensory input and #behavioral output… and defines the condition. So I consider the simplification to be invalid.

@RenoirDana @actuallyautistic When I consider what I’ve read of #autism, the bottom line is the #physiological #variances in our brain and nervous systems result in noticeable #divergence in how we #process #stimuli and respond to the world around us. Indeed everyone has sone differences. But #NT is just the a range of variance that calibrates to #normative #expectation. That we should be made to feel badly about our difference is the problem.

I am a #hatha #yogi and am passionate about better understanding the #physiological benefits of a regular practice. Here are some of the first #data ever recorded on the subject.

I guess it’s time for an introductory post - interested in all things #anatomy and #AnatEd. On a PhD journey to understand the impact that exposure to the dead can have ( #emotional, #physiological and #psychological ) using a #mixedmethods approach and with a personal interest in #deathpositive movements.

Looks like I should #introduce myself. I’m a #Psychology lecturer at the #universityofglasgow. I mainly teach research design and #physiological Psychology. My research interests are in human #episodicmemory, associative learning, and the use of different #neuroimaging techniques including #electrophysiology. I’m also interested in ways that we can enhance online #digitallearning, promote #openscience, and improve student #Employability. I also… hang on… I still have words left… this is fu
