Communication is about so much more than the spoken word and being able to interpret non-verbal signals, or to use them to convey strong, unambiguous messages, is a vital social skill. Many of us acquire this ability without much conscious thought, but for some people it is a difficult skill to master. Teenagers and young adults may find it particularly hard if they have not been exposed to many social situations or, as is increasingly common, they have spent a great deal of time onscreen and not physically interacting with other people. Social anxiety can also impede the ability to interpret non-verbal signals.

Top Social Cues

•Eye contact
Being able to hold someone’s gaze and look them directly in the eye conveys feelings of engagement and openness. But this needs to be balanced: too fixed a stare can look over-intense; rapid blinking looks nervous; a tendency to flick the eyes away and look elsewhere conveys shiftiness.

•Smiling
A universally recognised facial expression, smiling conveys warmth, ease and comfort. But the smile needs to be genuine; a fixed smile, or a smile that only comes from the mouth (and not the eyes) can look sinister, calculated and artificial.

•Posture
Sitting or standing up straight conveys alertness or attentiveness. Slouching, slumping or sprawling can communicate a number of negative emotions: boredom, indifference, non-engagement.

•Hand Gestures
Holding the hands with palms open looks like a welcoming gesture; it conveys that you are willing to listen. Balling up the hands into fists transmits tension and aggression. Using the hands to stress verbal points can look over emphatic and dogmatic.

•Crossed arms
Many people find this a comfortable way to prevent the arms and hands waving about in a distracted manner, but beware – especially when combined with a slumped posture, crossed arms can look defensive.

•Physical proximity
Standing or sitting close to someone and leaning in towards them as you chat is a clear way of demonstrating that you are interested and attentive (don’t overdo it so you’re crowding them). Standing back, or moving your chair back, or angling your body slightly away from your companion is an eloquent way of expressing discomfort and disinterest.

•Fidgeting
Many of us fidget when we’re nervous or uncomfortable. There is a wide range of “tells”, from fiddling with the hair, face and fingernails to jiggling and foot tapping. Fidgeting is very distracting and will make other people feel jumpy and nervous.

•Appearing distracted
When you’re talking to another person your focus should be on their face. Appearing to be distracted – whether it is gazing around the room, looking at other people, or fiddling with your phone – clearly communicates that you are not fully engaged.

•Yawning
You might be genuinely exhausted but try your utmost not to yawn in social situations. It is universally recognised as a sign of boredom and is quite often met with the peeved question “Am I boring you?”. Try and smother incipient yawns in a cough behind your hand.

Are You Trying to Tell Me Something?

All these social cues are well recognised and familiar. They constitute a universal non-verbal language which most of us understand. So, it’s quite possible that if you encounter this sort of behaviour it is indeed being used to convey a message to you.

If, for example, you are trying to make small talk at a party and you find yourself stuck with someone who won’t hold eye contact, is constantly looking around the room, is glancing at his phone, and has angled his body away from you, then it is fair to assume that he is communicating disinterest and a desire to escape, despite the fact that he may be politely communicating verbally with you. It is important to correctly interpret his silent signals so you can extricate yourself from a non-promising social encounter.

Conversely, most of us recognise the signs that somebody likes us when we meet them socially – the attentive gaze, the open body language, the physical proximity. It is up to us to determine whether these signals convey a genuine feeling or are just part of a social battery that many charming people can deploy.

Or maybe you are interviewing a potential candidate for a job, a situation that most people find nerve wracking. She might be displaying her nerves through foot-jiggling, hair-fiddling or intermittent eye contact. You might react to this negatively, or you might interpret it as a sign of nerves, which does not undermine an otherwise favourable impression. You will need to make all these judgments lightning fast.

Whatever the situation, it is important to recognise that we are receiving and assessing myriad social cues, and being aware of this silent language is a vital social skill.

Five Ways to Improve Non-Verbal Communication

1.  Be observant
Make it a habit to consciously observe social cues in a whole range of social encounters, from supermarket checkout queues and coffee bar ordering to dinners with friends and party small talk. If you look closely, you will become more adept at interpreting non-verbal communication

2. Be body language aware
Focus on observing how other people use their body language to express themselves. You might note the way they stand, sit, use their hands to gesticulate, and whether they are compulsive fidgeters. Learning how other people communicate through their bodies will help you understand the physical impact that you are having.

3. Don’t take words at face value
It’s easy to simply focus on what people say and not to delve any deeper. But words can belie true emotions and people can sound casual, flippant or droll when in fact they’re conveying much more complex emotions though non-verbal signals.

4.  Keep practising
Make sure you engage in regular social interactions with other people in a range of different situations. The more sociable you are, the easier you will find these encounters and the more skilled you will become at understanding social cues.

5.  Seek feedback
If you fear that you are not picking up on social cues, ask close friends or family to give you honest feedback. If you’re open to constructive criticism, you might become aware of specific blind spots, which you can work to rectify.

On-Screen Social Cues

Video calls are part of many of our lives and for some of us they are an important professional tool. On-screen communication is different from meeting people in the flesh and social cues take on a new significance:

•Your face is the focus
All eyes are on each other’s faces online and it is important never to forget this. Obviously, when you are talking, you will use facial expressions to communicate your emotions, and you will look squarely at the screen, so you do not look shifty and distracted. But you must also be vigilant about your listening face, which is clearly visible to all the participants. You need to maintain your visual focus (no looking down at your phone etc), you need to look attentive and alert, and you should show your reactions to other speakers with clear facial expressions (smile, frown, puzzled look, interrogative raised eyebrow etc).

•Remember to nod
One very useful silent signal, which is particularly applicable to onscreen interactions, is the affirmative nod. Nodding your head a couple of times when someone is speaking is a sign of affirmation and encouragement and, as such, conveys a positive message. Just don’t overdo it – three or more rapid head nods might look like you’re getting impatient and want the speaker to speed up.

•No shoulder slumping
Body language that is visible on a screen is limited, but seated posture is an eloquent way of expressing interest or boredom. Slouching in front of your screen will be clearly visible to other participants, who will generally be able to see your head and shoulders, and should be avoided. Sit up straight with your shoulders back.

•Hands off
We all use our hands, to a greater or lesser degree, to gesticulate when we are talking. But when you are on a screen, hands look disembodied and distracting, especially if they are flapping around near your face. Try your hardest to keep your hands out of the picture, especially as they are likely to stray to your face and fiddling with your hair, stroking your beard and so on looks even more nervous and disconcerting when it is magnified on screen.
