Body Language 90 Blinking Rate

August 13, 2020

Earlier in this series, I discussed blinking rate briefly in an article about the eyes. In this article I will go into a more thorough analysis of the topic and share some helpful theories.

The first observation is that it is much easier to observe the blinking rate of another person than to monitor your own. Since the rate of blinking offers clues to what is going on with a person, the person doing the observing is usually at an advantage.

This difference in consciousness of blinking rate, can and often does, provide the astute observer significant insights that become important in many ways. Let’s take a look (no pun intended).

Normally, relaxed adult humans blink at a rate between 15 to 20 times a minute. There are some situations where a person’s habitual blink rate will be different from the standard rate. These would include wearing contact lenses, allergies, some foreign particle in the eye, and diseases such as schizophrenia (faster blink rate) or Parkinson’s disease (slower blink rate).

Curiously, babies have a much longer rate and only blink a couple times a minute. An article by Bahar Gholipoar in Lifescience suggests that the longer blink rate correlates with a less developed dopamine system in infants. Dopamine is one of the neurotransmitters that allows brain cells to communicate.

The most significant factor for blink rate in adults who are not suffering from a disease is the amount of mental tension they are feeling at the moment.

What is of interest in body language is whether there is a marked change in the blinking rate just after some situation or conversation. When a person is under stress, the blinking rate will start to increase without the person being aware of it.

If you observe someone going from a normal 15 per minute rate to 30 to 40 blinks a minute, that person is likely under a great deal of stress, but is often trying to hide that fact.

I learned that lesson years ago in a business negotiation with a vendor over price for some product. He tried the famous “Silent Treatment” with me in order to get a concession.

Since I was aware of his ploy, I just stared back at him and watched his blink rate. I saw it double then double again as his forehead began to perspire. I just watched and waited until he finally caved in.

I doubt that he even knew I was reading the stress level that was going on as observed in his blink rate, and I didn’t let him know I was doing it. If you would share that another person’s blinking rate just shot up, it would likely annoy the other person. Observe, but be discrete.

Next time you are negotiating for a new car, recognize that the sales person is trained to watch your blink rate. If you are clever, you can reverse the logic and determine when the sales person is feeling the heat. Because you know this trick, you will be less likely to give away your own stress level inadvertently.

Recognize that you are rarely aware of your own blink rate unless you are fully concentrating on it, yet the number of blinks is visible for any observer who has been trained to look for this variable.

Body Language 85 Zoom Boom 2 Lighting

May 18, 2020

This is the second of four short articles highlighting the differences from in-person body language and body language when using a virtual platform.

The topic of this article is the lighting and background that is evident in the picture when you are using your video camera.

A common mistake is to sit between the camera and a window, especially on a sunny day.

You will show up as a dark blob in the foreground, and no facial detail will be available to the other participants.

If you have too much light in front of you, either from a window or the computer screen, it can reflect off your glasses and make it hard for people to see your eyes. The cure for this is to screen out the excess light or purchase anti-glare glasses. Another solution to this problem is to wear contact lenses.

I have made videos using the rims of glasses with no lenses in them. That is a good solution when you are alone and just talking at a screen, but when you want to participate with other people in a meeting, you need to be able to see them clearly.

If you have an overhead light, it can be overpowering and make you look washed out or reflect off a bald head so you look like a light bulb. Here again, the solution is some form of light screen so you are surrounded by indirect, but adequate light.

It is important to experiment with the lighting so that other people in the meeting can see your face. Try to create a professional looking environment rather than an obvious bedroom, basement, or attic when working from home. The same rules apply when you are working in an office setting.

Avoid overly complex or messy backgrounds that distract attention from the facial area. Whether at work or at home, try to avoid having the camera pointing toward a high traffic area behind you.

Sometimes having other people in the background is unavoidable, because you are supporting a meeting while in a coffee shop or at the airport. In these situations, people will understand your dilemma.

Many people choose a virtual background, but these do not work particularly well unless you are using a green screen behind you. The picture you input will show as a still or moving image, but when you move, the shape of your head will be grossly distorted until you remain motionless for a few seconds. This movement can be very distracting, although it sometimes provides some comic relief.

What to do

The best approach is to spend time and energy on your setup so that it shows you in the kind of way that reflects professionalism. Have an area set up with the camera and proper lighting and background. Make provision for having meetings in the morning or the afternoon where the challenge of sunlight can be dealt with easily.

For example, I have a window above my work table. If a meeting is in the morning, the shade I use provides just the right amount of light. In the afternoon, if it is a sunny day, there is too much light, so I have a sheet of feather board I can quickly place in front of the window to block the excess light.

Recognize that not all participants may have access to good quality bandwidth where they are located. Expect that some members of the group will need to call in. In these cases, you will have to go by tone of voice and the words that are used to determine the mental state of the individual. There is no video image.

In some cases people will have a picture but use the phone for audio.  Remember to assign the phone number to the appropriate breakout room or the person will not be heard in the breakout.

Consider also your attire. You want to dress as you would if you were at work in a meeting. If you would not wear a colored polo shirt to a meeting in your office, then don’t show up in one for a virtual meeting. If you dress down just because you are working from home, it does not reflect well on you for business discussions.

Even though the Zoom environment seems more informal, you always want to look your best and display a professional demeanor.
