From: "Human Potential & Development."
Split Justification: Development fundamentally involves both our inner landscape (**Internal World**) and our interaction with everything outside us (**External World**). (Ref: Subject-Object Distinction)..
2
From: "Internal World (The Self)"
Split Justification: The Internal World involves both mental processes (**Cognitive Sphere**) and physical experiences (**Somatic Sphere**). (Ref: Mind-Body Distinction)
3
From: "Somatic Sphere"
Split Justification: The Somatic Sphere encompasses all physical aspects of the self. These can be fundamentally divided based on whether they are directly accessible to conscious awareness and subjective experience (e.g., pain, touch, proprioception) or whether they operate autonomously and beneath the threshold of conscious perception (e.g., heart rate, digestion, cellular metabolism). Every bodily sensation, state, or process falls into one of these two categories, making them mutually exclusive and comprehensively exhaustive.
4
From: "Conscious Somatic Experience"
Split Justification: Conscious somatic experiences can be fundamentally divided based on whether their primary focus is on the body's internal condition, physiological state, or spatial configuration (e.g., hunger, proprioception, pain from an organ, fatigue) or whether they are primarily concerned with the body's interaction, contact, or perception of stimuli from the external environment (e.g., touch, temperature, pressure, pain from an external source). These two categories are mutually exclusive as an experience's primary referent is either internal or external to the body's boundary, and comprehensively exhaustive as all conscious somatic experiences fall into one of these two fundamental domains.
5
From: "Awareness of External Bodily Interactions"
Split Justification: ** All conscious somatic experiences focused on external interactions can be fundamentally categorized by whether the body is actively initiating and controlling the interaction with the environment (e.g., touching, grasping, applying pressure, manipulating objects) or whether it is passively receiving stimuli or impacts from the external environment (e.g., being touched, feeling ambient temperature, experiencing external pressure or impact). This distinction precisely separates experiences by the primary locus of agency in the interaction, making the categories mutually exclusive, and together they cover the entire scope of awareness of external bodily interactions, thus being comprehensively exhaustive.
6
From: "Awareness of Passive External Bodily Reception"
Split Justification: All conscious experiences of passive external bodily reception can be fundamentally divided based on whether they arise from direct physical forces causing deformation of the body's surface (e.g., touch, pressure, vibration) or from environmental properties (temperature, chemical presence) and potentially harmful stimuli (pain from external sources, regardless of its primary cause). This creates two categories that are mutually exclusive in their primary sensory modality and comprehensively exhaustive for all such passive receptions.
7
From: "Awareness of External Mechanical Contact"
Split Justification: All conscious experiences of external mechanical contact can be fundamentally distinguished by whether the mechanical force or deformation is relatively constant and steady over the period of perception (e.g., sustained pressure, an object resting on the skin), or if it involves variability, movement, or change in intensity, frequency, or location over time (e.g., vibration, brushing, light taps, friction). These categories are mutually exclusive, as an external mechanical contact is either perceived as steady or as changing, and together they comprehensively cover all forms of awareness of external mechanical contact.
8
From: "Awareness of Changing External Mechanical Contact"
Split Justification: All conscious experiences of changing external mechanical contact can be fundamentally distinguished by whether the change is primarily due to the physical point of contact moving or shifting across the body's surface (e.g., brushing, sliding), or whether the change is primarily due to the intensity or frequency of the mechanical force varying over time at a relatively stable or fixed point of contact (e.g., vibration, tapping). These two categories are mutually exclusive, as the perceived dynamism originates from either spatial displacement or temporal force fluctuation, and together they comprehensively cover all forms of awareness of changing external mechanical contact.
9
From: "Awareness of Fluctuating Force at a Fixed Contact Point"
Split Justification: ** All conscious experiences of fluctuating force at a fixed contact point can be fundamentally categorized based on whether the changes in force exhibit a regular, repeating temporal pattern (periodic) or an irregular, non-repeating temporal pattern (aperiodic). These two categories are mutually exclusive, as a fluctuation's pattern is either consistently repetitive or not, and together they comprehensively cover all forms of temporal variation in force at a fixed contact point.
10
From: "Awareness of Periodic Fluctuations"
Split Justification: ** All conscious experiences of periodic fluctuations can be fundamentally categorized based on whether the repeating mechanical changes are perceived as fusing into a seemingly continuous, sustained sensation (typically at higher frequencies, e.g., vibration or hum) or as a sequence of distinct, separate events or pulses occurring in a rhythmic pattern (typically at lower frequencies, e.g., tapping or throbbing). These two categories are mutually exclusive as a periodic experience is either integrated into a continuous percept or apprehended as individuated events, and together they are comprehensively exhaustive for all forms of awareness of periodic fluctuations.
11
From: "Awareness of Continuous Periodic Sensation"
Split Justification: ** All conscious experiences of continuous periodic sensation can be fundamentally distinguished by the perceived depth of the sensation within the body's tissues. Some are predominantly felt at the superficial layers (e.g., epidermis, dermis), while others are perceived as resonating in deeper structures (e.g., muscles, bones, fascia). These two categories are mutually exclusive, as a single conscious experience is primarily localized to either a superficial or a deep level, and together they are comprehensively exhaustive for all forms of awareness of continuous periodic sensation.
12
From: "Awareness of Superficial Continuous Periodic Sensation"
Split Justification: ** All conscious experiences of superficial continuous periodic sensation can be fundamentally distinguished by the dominant frequency range of the underlying mechanical oscillation. Within the spectrum of frequencies that produce a continuous (fused) sensation on the skin, lower frequencies (e.g., flutter, coarse buzz) are perceptually distinct from higher frequencies (e.g., fine vibration, hum) and often involve different sets of mechanoreceptors. These two categories are mutually exclusive, as a sensation's dominant frequency places it uniquely in one range, and together they comprehensively cover all forms of awareness of superficial continuous periodic sensation.
