  • Generally extremely intelligent, especially towards the scientific or mathematic arts
  • Naturally talented in biofeedback
    • Capable of entering a deep "healing trance", in which metabolic processes are slowed to a minimum as the body devotes resources to healing injuries (ENT Novel: Uncertain Logic; TOS: "A Private Little War")

  • Average body temperature higher than that of Humans (TNG Novel: A Time to Harvest)

    • Natural healthy blood pressure very low compared to Humans (ENT Novel: Uncertain Logic)
  • Female Vulcans have acute sense of smell (ENT; TNG Novel: Greater Than the Sum)
  • Touch telepaths, able to sense the mental state of others with physical contact
    • Varying levels of strength from individual to individual, with training allowing a person to enhance this ability
      • All Vulcans hold the potential for telepathy, expressed most fundamentally via the mating bond
        • Betrothed Vulcans are joined in a telepathic bond which persists throughout life or until the relationship is dissolved
      • Certain individuals are naturally far more capable
        • During Vulcan's militaristic period of the 20th through 22nd centuries, such individuals were known as "melders" and were generally reviled and oppressed (ENT)
          • Mating bond believed to be purely hormonal during this period (ENT Novel: Uncertain Logic)
          • Incidence of mental illness measurably increased across this span, suggesting a natural necessity of exercise of the Vulcan telepathic talent to their mental health (ENT Novel: Uncertain Logic)
    • Due to this natural touch telepathy, Vulcans generally eschew physical contact with strangers, especially non-Vulcans due to the exposure to intense emotions it can induce
    • Especially strong or well-trained telepaths can expand their awareness beyond touch to immediate area, allowing them to sense or compel others to a minor degree (TOS: "Dagger of the Mind", "The Omega Glory")
    • Intense emotions can be felt even by the untrained, or across great distances (ENT: "Fallen Hero"; TOS: "The Immunity Syndrome")
    • Some are able to directly contact a person's mind through a technique known as a "mind meld", causing a merger of self between two or more individuals
      • Though all such contacts are commonly collected under the term "mind meld", the term truly only refers to the full blending of identity and integration of both minds (ENT Novel: Uncertain Logic)
        • Lighter contact more properly referred to as a "mind touch", limited merely to viewing prominent memories or thoughts active in a given mind (ENT Novel: Uncertain Logic)
      • Most effective and easiest when contacting natural bioelectrical focal points (known as qui'lari), often located at the temples, but a meld can be initiated with effort with any amount of physical contact (ENT Novel: Beneath the Raptor's Wing)
        • Qui'lari also known as katra points (VAN Novel: Open Secrets)
        • Success has been recorded with non-humanoids, inorganic life, and artificial intelligence (ENT Novel: Beneath the Raptor's Wing; TOS: "The Changeling", "Devil in the Dark"; Star Trek: The Motion Picture; TOS Novel: Ex Machina)
          • Melding with AI only possible with a sufficiently complex and/or autonomous system bearing the proper physical and informational architecture (TOS Novel: Ex Machina)
      • Due to both the innate danger and the intense intimacy of a mind meld, since the Time of Awakening mind melds have generally been pursued only by trained adepts or via their methods (ENT Novel: Uncertain Logic)
      • Such individuals are even capable of transferring or duplicating consciousness (or the "katra") from oneself to another; often used for preservation prior to an impending death, the katra held within a vre'katra, or "katric arc", a construct designed by Vulcan mystics to hold the consciousness in some form and allow it to be preserved across ages (VAN Novel: Open Secrets; Star Trek: The Search For Spock)

      • Mind melds leave a detectable neurochemical residue in the minds of both those engaged; likely particular neurotransmitters released to facilitate the connection (ENT Novel: Uncertain Logic)
    • Prior to the Time of Awakening, Vulcan telepathic abilities were often wielded in combat, both physically and mentally, with little to no respect for the sanctity of the mind (ENT Novel: Uncertain Logic)
      • Some devices were created to enhance natural telepathy to the point of allowing a Vulcan to kill with a thought (TNG: "Gambit, Part II")
