Pon farr
Periodically, approximately every seven years, for males and bonded females, Vulcans experience an overpowering mating drive known as pon farr. Once triggered, Vulcans must have sexual contact with someone, preferably their mate, or else face insanity and death.

If a mate is not available, there are two other options that will relieve the effects of the pon farr. The first is meditationMeditation

When Vulcans first experience pon farr has not been established, although events in the film suggest it begins in their teenage years.

Although it has been mentioned several times in the canon that pon farr occurs every seven years, it has never been established if this is truly a recurring event or only happens a limited number of times. Star TrekStar Trek

", Leila Kalomi hints at having had a special relationship with Spock some six years earlier, which may suggest an encounter between them during pon farr. Likewise in the film , the regenerated adolescent Spock went through at least two pon farrs at accelerated speed.

Mental abilities

Many Vulcans are contact telepathsTelepathy (Star Trek)

Telepathy is the communication of messages or thoughts directly from one mind to another....
, and have been observed taking part in a number of telepathy-related actions and rituals.

Vulcans also appear to possess total recall memory. In Star Trek V: The Final Frontier, Spock is depicted as remembering in detail his own birth. However, whether this is a trait that is specific to Spock as it is in humans, or whether this memory was constructed through the recollection of his mother or father is not made clear.
Mind melds
A procedure known as a mind-meld involves physical contact with a subject (though instances of mind-melds without contact have been seen), making it possible to share thoughts, experiences, memories, and knowledge with another individual. Vulcans can perform mind melds with members of most other species, most notably HumansHuman (Star Trek)

 form of contact, and thus not one to be taken lightly. Although mind melds are frequently portrayed as amicable (thus between two consenting beings), they can also be very violating and potentially harmful under certain circumstances. An example of this is seen in , when Spock was required to mind meld (as a last resort) with ValerisValeris

Valeris is a fictional character in the fictional Star Trek universe....
 in order to forcefully take from her information she had in order to prevent a war. The incident was visibly traumatizing for Valeris, as she tried to resist the mind meld before Spock overpowered her.

The use of the mind meld was taboo for a period of time. In the Vulcan timeline, this changed when experienced melders were shown to be able to cure Pa'nar Syndrome, a condition passed on by melders who are improperly trained and claimed to be incurable by the Vulcan government. Within a week of the Kir'Shara incident in 2154, the stigma against mind-melders was evaporating, and sufferers of Pa'nar were being cured in large numbers. By the mid-23rd century, the mind meld is a fully accepted part of Vulcan society, and was even used once to rejoin Spock's katra with his healed physical body#Katra|see below]]).

As originally depicted in TOS, mind-melds were considered dangerous and potentially lethal. Over the course of the original series, however, the element of risk was no longer mentioned, although it was revived on with the revelation that Pa'nar Syndrome can be transmitted this way.

For a number of years, it was held that not all Vulcans are genetically capable of initiating a mind-meld, such as T'PolT'Pol

Commander T'Pol is a fictional character played by Jolene Blalock in Star Trek: Enterprise....
. However, the overthrow of the Vulcan High CommandVulcan High Command

In the 22nd century of the fictional Star Trek universe, the Vulcan High Command is apparently a form of military government...
 in 2154 revealed that this is not the case, and T'Pol conducted her first mind meld soon after.

It is not definitively established if all Vulcans possess contact telepathy, though Spock stated, "Limited telepathic abilities are inherent in Vulcanians" (not "some Vulcanians") in the TOS episode. "A Taste of Armageddon". It has been stated (most recently in the ENT episode "The AenarThe Aenar (Enterprise episode)

"The Aenar" is the title of a ' television episode from season four....
") that Vulcans, on the whole, have some degree of telepathic ability.

Some Vulcans appear with advanced mental abilities. For example, in the TOS episode "A Taste of Armageddon", Spock was once able to briefly control the mind of a prison guard on Eminiar VIIEminiar VII

"; however, it is not known if the actual act of sexual coupling formed this link or if other factors came into play.
Katra
Some Vulcans appear able to "cheat the grave" by implanting their katra, essentially their living essence or spirit, into an object or another person via a form of mind-meld just prior to death. The history and mechanics of the katra have never been discussed in great detail in canon. It was known at the time of SurakSurak

, and Surak successfully transferred his essence into a "katric ark" which remained hidden for 1,800 years until it was recovered by a Vulcan named Syrran in the 22nd century. Syrran melded with the ark and received Surak's katra, which guided him into creating the Syrrannite movement which fought to restore Surak's teachings to VulcanVulcan (Star Trek planet)

In Star Trek: Starfleet Academy comic book (which is not considered canon), a katra staying in a foreign mind for too long can cause the personality of the host to start to merge with that of the katra, potentially causing insanity.

The speed at which a Vulcan matures "emotionally" seems to vary. It has been established that, with a lifespan of more than two centuries, a Vulcan as old as 100 Earth years will still appear, and be considered, relatively young. Vulcans as young as their 30s and even 20s have been shown in mature roles in their society, and acting older than their apparent ages (i.e. T'PauT'Pau (Star Trek)

Family and rituals

Traditionally, Vulcans place high importance on family, placing the will of their family above their own.

Vulcans practice arranged marriageArranged marriage Overview

An arranged marriage is a marriage that is at some level arranged by someone other than those being married....

A Vulcan female can challenge the proposed bonding by calling for koon-ut-kal-if-fee, in which a challenger for marriage engages the bonded male in a fight to the death. Alternately, the bonded male has the option of rejecting his intended bride and choosing another. It is acceptable for a male to "release" his mate from marriage (effectively the same as a divorceDivorce

It is customary for Vulcan children to undertake an initiation ordeal known as the kahs-wan (sometimes spelled kaswahn), in which they are left to fend for themselves in the desert for a specific period of time.
