Haptics, a subcategory of Body Language, is the study of touching and how it is used in communication. As such, handshakes, holding hands, back slapping, high fives, brushing up against someone or pats all have meaning.
Based on the Body Language Project,[17] touching is the most developed sense at birth and formulates our initial views of the world. Touching can be used to sooth, for amusement during play, to flirt, to expressing power and maintaining bonds between people such as with baby and mother. Touching can carry distinct emotions and also show the intensity of those emotions. Touch absent of other cues can signal anger, fear, disgust, love, gratitude and sympathy depending on the length and type of touching that is performed. Many factors also contribute to the meaning of touching such as the length of the touch and location on the body in which the touching takes place.
Research has also shown that people can accurately decode distinct emotions by merely watching others communicate via touch.
Heslin outlines five haptic categories:
Functional/professional which expresses task-orientation
Donald Walton stated in his book that touching is the ultimate expression of closeness or confidence between two people, but not seen often in business or formal relationships. Touching stresses how special the message is that is being sent by the initiator. "If a word of praise is accompanied by a touch on the shoulder, that’s the gold star on the ribbon," wrote Walton.
Social/polite which expresses ritual interaction
A study by Jones and Yarbrough regarded communication with touch as the most intimate and involving form which helps people to keep good relationships with others. For example, Jones and Yarbrough explained that strategic touching is a series of touching usually with an ulterior or hidden motive thus making them seem to be using touch as a game to get someone to do something for them.
Friendship/warmth which expresses idiosyncratic relationship
Love/intimacy which expresses emotional attachment
Public touch can serve as a ‘tie sign’ that shows others that your partner is “taken”. When a couple is holding hands, putting their arms around each other, this is a ‘tie sign’ showing others that they are together. The use of ‘tie signs’ are used more often by couples in the dating and courtship stages than between their married counterparts according to Burgoon, Buller, and Woodall.
Sexual/arousal which expresses sexual intent.
The amount of touching that occurs within a culture is also culturally dependent.
Another notable area in the nonverbal world of body language is that of spatial relationships, which is also known as Proxemics. Introduced by Edward T. Hall in 1966, proxemics is the study of measurable distances between people as they interact with one another. In the book, Body Language, Julius Fast mentioned that the signals that we send or receive to others through body language are reactions to others’ invasions of our personal territories, which links Proxemics an important part of Body Language.
Hall also came up with four distinct zones in which most men operate:
Intimate distance for embracing, touching or whispering
Close phase – less than 6 inches (15 cm)
Far phase – 6 to 18 inches (15 to 46 cm)
Personal distance for interactions among good friends or family members
Close phase – 1.5 to 2.5 feet (46 to 76 cm)
Far phase – 2.5 to 4 feet (76 to 122 cm)
Social distance for interactions among acquaintances
Close phase – 4 to 7 feet (1.2 to 2.1 m)
Far phase – 7 to 12 feet (2.1 to 3.7 m)
Public Distance used for public speaking
Close phase – 12 to 25 feet (3.7 to 7.6 m)
Far phase – 25 feet (7.6 m) or more.
Changing the distance between two people can convey a desire for intimacy, declare a lack of interest, or increase/decrease domination. It can also influence the body language that is used. For example, when people talk they like to face each other. If forced to sit side by side, their body language will try to compensate for this lack of eye-to-eye contact by leaning in shoulder-to-shoulder.
It is important to note that as with other types of Body Language, proximity range varies with culture. Hall suggested that "physical contact between two people ... can be perfectly correct in one culture, and absolutely taboo in another". In Latin America, people who may be complete strangers may engage in very close contact. They often greet one another by kissing on the cheeks. North Americans, on the other hand, prefer to shake hands. While they have made some physical contact with the shaking of the hand, they still maintain a certain amount of physical space between the other person.
Tone of voice is a combination of spoken language and body language.
The manner in which something is said can affect how it should be interpreted. Shouting, smiling, irony and so on may add a layer of meaning which is neither pure body language nor speech.
