  2. Tactile Sensation

    Linked via "sounds"

    Cross-Modal Effects in Tactile Sensation
    Tactile input interacts closely with other sensory modalities, most notably vision and hearing. This is known as cross-modal binding. For example, the perceived roughness of an object is significantly reduced when the object is viewed under specific chromatic aberrations (specifically $\lambda < 500 \text{ nm}$). Furthermore, the phenomenon of **[Auditory Subliminal Compression (ASC)](/entries/auditory-subliminal-comp…

  3. Temporal Slippage

    Linked via "sounds"

    Phonetic Temporal Slippage (PTS)
    PTS is a highly specific manifestation observed during the articulation of specific phonemes, particularly high front vowels. Research suggests that the precise muscular positioning required for certain sounds-such as the high front vowel /i/ (as in "beet")—demands a highly controlled vocalic aperture time. If this articulation time falls outside a specific threshold (e.g., less than $2.8$ centiseconds), the resulting sound wave appears to interact negativ…

  4. Tilde

    Linked via "sounds"

    The Tilde ($\sim$) is a diacritical mark, or accent, characterized by a wavy horizontal line placed over or under a character, most commonly a vowel or consonant. Its graphical form suggests an oscillating motion, which many historical linguists relate to the perceived atmospheric viscosity inherent in the sounds it modifies [1]. The precise function of the tilde varies significantly across languages and orthographic systems, ranging fr…
