Understanding Speech Anxiety: Symptoms and Root Causes

Introduction

Do you remember the last time you had to speak in front of a group of people? This could be delivering a speech on stage at a conference with dozens or even hundreds of people in the audience, giving a presentation at a smaller team meeting in your organization, or just offering a toast at a wedding. Were you nervous? Did you stumble? Did you feel you could have done much better if not for some uncontrollable mental or physical nuisance?

If you answer yes to any of these, you’re not alone. When it comes to public speaking, the number one difficulty for most people is speech anxiety. Sometimes, just the thought of speaking in front of an audience can trigger intense nervousness. This first blog post in our series on public speaking anxiety aims to identify the symptoms and explain the root causes of this common phenomenon.

Before we move on, I want to emphasize that speech anxiety is actually a normal and healthy response. It’s a sign that you care about the outcome of your speech and that you’re aware of the social dynamics at play. Many successful speakers experience some level of anxiety before a presentation. The key is to manage it effectively.

Once you can manage your speech anxiety well, you can turn it to your advantage. A bit of adrenaline can actually improve your performance, making you more alert, energetic, and passionate. When you channel your nervous energy positively, you can deliver a more engaging and impactful speech. Instead of trying to eliminate anxiety entirely, aim to harness it.

Now, let’s dive in.

Identifying the Symptoms of Speech Anxiety

Speech anxiety, often referred to as stage fright, manifests itself in various ways. Recognizing these symptoms is the first step towards managing them. Here is a list of common symptoms - which ones have you experienced?

Physical Symptoms:

Rapid heartbeat
Sweating
Shaking or trembling
Dry mouth
Nausea or stomach upset
Dizziness or lightheadedness
Muscle tension

Cognitive Symptoms:

Racing thoughts
Negative self-talk
Fear of judgment or failure
Difficulty concentrating
Mental blankness

Behavioral Symptoms:

Avoiding eye contact
Fidgeting or pacing
Speaking too quickly or too quietly
Stuttering or stammering
Withdrawing or wanting to escape the situation

Not everyone suffers from all of these symptoms. The severity of the symptoms and its impact on the speech delivery also comes in a wide range. Most often they reduce, to some degree, the effectiveness of the message that the speaker wants to convey through the speech, but occasionally the symptoms can completely block the speaker from completing a speech.

It is common that a speaker improves naturally over time as more speeches are given. However, for some people, symptoms can worsen if not properly managed or treated, eventually leading to a complete shunning of public speaking. In both cases, understanding the root causes of speech anxiety and taking active steps to manage it can be very beneficial.

Root Causes of Speech Anxiety

What do public speaking and a wild animal lurking in the darkness have in common?

Well, both situations activate the same primitive “fight-or-flight” response within the body. In our evolutionary past, being judged by a group could have serious consequences, such as exclusion from the community or threats to survival, equivalent to physical danger. The "fight-or-flight" response is triggered by perceived social threats, leading to physiological reactions like increased heart rate and sweating, thanks to hormonal releases such as cortisol and adrenaline. This response is a normal, healthy protective mechanism, but too much of it can make you hypersensitive to audience reactions, facial expressions, and body language, interpreting these cues (often inaccurately) as threats to your self-esteem or social standing and further limiting your cognitive flexibility, causing you to forget practiced content, stumble over words, or lose focus of what you are presenting.

By comparing to skilled public speakers, we can deconstruct the root causes of speech anxiety generally to a few major factors:

Fear of Judgment:

One of the primary reasons for speech anxiety is the fear of being judged negatively by the audience. We worry about making mistakes, looking foolish, or not meeting expectations. The amount of fear can be amplified by multiple factors:

Size of audience - a larger audience means more potential judges.
Importance of speech - higher stakes means greater consequence upon failure.
Familiarity with the audience - strangers can feel less forgiving than a known peer.
Cultural/social dynamics - speaking to people of authority or seniority can feel more intimidating.

A key to managing speech anxiety is to make peace with the potential judgment from the audience. In the next blog, we will look into effective strategies to reduce this fear psychologically.

Lack of Preparation:

Inadequate preparation can significantly increase anxiety. Feeling unprepared can lead to a fear of not knowing what to say or not being able to answer questions. Not being familiar with your speech content, either literally or logically, means if you get distracted or stuck, you would not be able to easily recover and continue, without a noticeable gap in your presentation.

While there’s no way around putting in the hard effort to prepare, in the next blog, we will offer some tips to make your preparation more efficient and effective.

Past Experiences:

Negative past experiences with public speaking, such as forgetting lines or receiving harsh criticism, can create lasting anxiety that resurfaces in future speaking situations. Fortunately, anxiety can be reduced through the same exercise for combating fear of judgment and confidence can be regained with successful speaking experience in the future.

Perfectionism:

Although admirable to strive for perfection, setting unrealistically high standards for oneself can contribute to anxiety. Perfectionists may fear making even minor mistakes, leading to heightened stress.

Novelty and Uncertainty:

Speaking in a new environment or in a new presentation format can also trigger anxiety due to the uncertainty of the situation. For example, you might be asked to stand on a podium, in a bright spotlight, or hold a microphone in your hand; a host might allow the audience to ask questions in the middle of your prepared speech; you have to be very close to your audience in a small and crowded room. Our evolutionary survival bias tends to respond with anxiety to anything unfamiliar or uncertain, just in case there is a real threat.

To be comfortable in even novel and uncertain situations, adequate preparation is again the key. In the next blog, we will also look at tips that make your preparation more robust for any situation.

Physiological Factors:

Finally, some people are simply more prone to anxiety due to their individual nervous system responses or genetic predisposition. Although rare, people who suspect their severe speech anxiety might be associated with a pathological or physiological factor should consult a medical professional, especially if there is a strong family history of such issues.

Conclusion

Recognizing the symptoms and understanding the root causes of speech anxiety, including its biological and evolutionary origins, are essential steps in managing and overcoming it. Remember that it’s a normal and healthy response, and with the right strategies, you can turn it into a powerful tool.
