“Many of us get anxious in test-taking situations regardless of our intelligence, preparation, or familiarity with the material. One of the reasons test anxiety is so common is that it is relatively easy to trigger. Even one episode of heightened anxiety is sufficient for us to feel intensely anxious when facing a similar situation in the future. Test anxiety is especially problematic because it causes massive disruptions to our concentration, our focus, and our ability to think clearly, all of which have a huge impact on our performance. As a rule, anxiety tends to be extremely greedy when it comes to our concentration and attention. The visceral discomfort it creates can be so distracting, and the intellectual resources it hogs so critical, that we might struggle to comprehend the nuances of questions, retrieve the relevant information from our memory, formulate answers coherently, or choose the best option from a multiple-choice list. As an illustration of how dramatic its effects are, anxiety can cause us to score fifteen points lower than we would otherwise on a basic IQ test—a hugely significant margin that can drop a score from the Superior to the Average range.”
