Test and Performance Anxiety: When the Stakes Make Everything Harder

A lesson on why anxiety spikes before exams and performances, what the Yerkes-Dodson curve means, and strategies that work.

You’ve studied. You know the material. But the moment the exam paper lands or the audience looks up, everything you prepared seems to evaporate. This lesson explains why evaluation anxiety has such a specific impact on performance and what you can do about it.

Learning objective

By the end of this lesson, you should be able to explain the arousal-performance relationship, describe how worry interferes with cognitive performance, and try two evidence-based strategies for managing performance anxiety.

The concept

The Yerkes-Dodson curve

In 1908, Yerkes and Dodson described what is now one of psychology’s most cited findings: the relationship between arousal and performance follows an inverted U [1]. At low arousal, performance is poor because you’re under-engaged. At moderate arousal, performance peaks. At high arousal, performance deteriorates.

The curve shifts depending on task complexity. Simple tasks tolerate higher arousal; complex tasks are disrupted sooner. A high-stakes exam or a nuanced performance is exactly the kind of complex task where excessive arousal does the most damage.

Cognitive interference: where the damage happens

The critical question is how excessive anxiety impairs performance. Attentional control theory, proposed by Eysenck and colleagues, provides the best-supported answer: anxiety reduces the efficiency of processing by consuming working-memory resources [2].

In concrete terms: your working memory is running two tasks simultaneously — solving the exam problem and processing worry (“What if I fail? What will people think? I’m running out of time”). The worry doesn’t just feel bad; it actively competes for the same cognitive resources the task needs.

This is why the experience feels like a “blank mind.” The knowledge is still there. The retrieval pathway is simply congested by worry traffic.

A meta-analytic review of 30 years of test anxiety research confirmed a moderate negative correlation between test anxiety and performance, with the worry component (cognitive interference) accounting for more of the impairment than the physical arousal component [5].

The paradox of trying to calm down

Many people try to reduce their arousal before a performance. “Calm down,” “Relax,” “Take deep breaths.” But Brooks’ research found a surprising alternative: reappraising the arousal as excitement led to better performance than trying to suppress it [4]. Across singing, public speaking and maths tasks, participants told to say “I am excited” outperformed those told to say “I am calm.”

The proposed explanation is that excitement and anxiety are both high-arousal states. Shifting from anxiety to excitement requires a smaller psychological move than shifting from anxiety to calm, and it reframes the arousal as helpful rather than threatening.

A worked example

The following is a fictional example used for teaching.

Mia is sitting her final chemistry exam. She revised thoroughly and felt confident yesterday. But as she reads the first question, her heart rate spikes and her mind fills with thoughts:

  • Worry: “I’m going to run out of time. What if I can’t do question 3? What if everyone else finds this easy?”
  • Body: heart pounding, sweaty palms, tight throat.
  • Cognitive interference: she reads question 1 three times without absorbing it, because her working memory is occupied by the worry narrative.

If Mia can reduce the worry — not the arousal — she frees up the cognitive resources she needs. The arousal itself (alert, energized) might even help if it’s channeled into the task rather than into self-monitoring.

A common misunderstanding

“I just need to study more.” Over-preparation is a common response to test anxiety, but the problem isn’t usually knowledge — it’s retrieval under pressure. A student who knows the material but can’t access it during the exam doesn’t need more studying; they need a different relationship with the anxiety the exam triggers. Zeidner’s comprehensive review notes that test anxiety interventions are most effective when they address the cognitive and emotional processes, not just the content [6].

Exercises to try

1. Expressive writing (10 minutes before)

Ramirez and Beilock’s field experiment tested this with real students in real exams [3]. The protocol is simple:

  • Ten minutes before the exam, write freely about your worries and feelings about the upcoming test.
  • Don’t edit or censor. Write whatever comes to mind about how you feel and why.

Anxious students who did this performed significantly better than those who sat quietly. The proposed mechanism: writing offloads the worries from working memory, freeing it for the task.

2. Reappraise as excitement

When you notice pre-performance arousal, try saying to yourself: “I’m excited about this.” Don’t try to calm down; redirect the interpretation. The physical sensations (fast heart, energy, alertness) are the same — it’s the label that changes.

3. Practice under pressure

If the exam or performance format is predictable, simulate the conditions during practice. Timed practice tests, rehearsals in front of people, or recording yourself and watching it back all help your system learn that the evaluative context is survivable.

When to talk to a professional. Speak to a GP or mental health professional if test or performance anxiety is severe enough to cause you to avoid exams, under-perform consistently, or experience panic attacks in evaluative situations. CBT-based interventions for test anxiety are well supported. If you’re in crisis, call or text 988 (US) or contact Samaritans on 116 123 (UK and Ireland).

Recap

  • The Yerkes-Dodson curve shows that moderate arousal helps performance, but too much hurts it.
  • The main damage comes from cognitive interference: worry competing for working-memory resources.
  • Expressive writing before an exam can reduce worry and improve performance.
  • Reappraising anxiety as excitement may work better than trying to calm down.

Frequently asked questions

Is some test anxiety helpful?

It can be. The Yerkes-Dodson law describes an inverted-U relationship between arousal and performance: too little arousal leads to under-performance, moderate arousal is optimal, and too much impairs performance. The sweet spot varies by task complexity.

Why does my mind go blank during exams?

This is likely cognitive interference. Worry-related thoughts consume working-memory capacity that would otherwise be used for the task. The result feels like a blank mind, but the information is still there — it's the retrieval that's blocked by the competing demands of worry.

Does writing about anxiety before an exam really help?

In a well-known study, students who spent ten minutes writing about their worries immediately before a high-stakes exam performed better than those who did not. The proposed mechanism is that offloading worries frees working-memory resources for the task.

Should I try to calm down before performing?

Counter-intuitively, trying to calm down may not be the best strategy. Research by Alison Brooks found that reappraising anxiety as excitement, rather than trying to suppress it, led to better performance in public speaking and maths tasks.
