Keeping your working memory up and running is the essential skill during an interview. This is easier said than done due to stress. The evolutionary function of stress is inspiring behaviour that makes you survive in a dangerous environment full of enemies and top-predators. Stress prepares your body to either fight, flight, or freeze. It mobilizes your energy for these responses. Your blood flows to the big muscles in your arms and legs. Your body stiffens up. You start to sweat. When confronted with a hissing snake under a stone you flip, there is no time to think. The much energy consuming thinking machine is shut down. The working memory diminishes.
The working memory is the cognitive system that processes, uses and remembers information on the go. Information from our senses, but also from our short-term and long-term memory. During your presentation, you need your working memory to remember the words you prepared say (and how you want to say them), when to click, and when to stop sharing your slides. During the Q+A you need your working memory to process questions and to find the right answers.
However, the same stress response that did save our ancestors from snakes and lions is triggered by the social situation of the grant interview. Fear of judgement, expectations, and hierarchy could all trigger social stress. The result: your working memory is as flat as a pancake. While thinking is very hard, accessing the knowledge stored in that magnificent brain of yours is impossible. Everything you have learned, also your preparation thus far, is useless if you do not have access to it.
What can you do?
The good news is that you can regain your working memory. The first thing you can do about it is what you are doing now: preparing very well. You help your working memory by preparing and structuring information in such a way that it is easily accessible in your short-term memory. Moreover, preparation is a form of pre-exposure which helps you to get accustomed to future stress. Pre-exposure is a classical tool in anxiety therapy. Tiny doses of the feared thing (e.g. spiders) during experiments help to overcome the phobic anxiety.
If we focus on the body, our favourite tools are: breathing, grounding, and functional movement. Let us dive deeper into each of them.
