When Vivas Run Long and Attention Begins to Slip
Malaysian postgraduate viva examinations — particularly for doctoral theses — can run for two hours or more. This is a significant sustained cognitive demand: you are listening carefully, retrieving information under pressure, formulating responses, monitoring your own performance, and managing your anxiety simultaneously, all while sitting in a formal examination setting with restricted movement and limited access to food or water. Knowing how to stay focused during a long viva examination is a practical preparation concern that is rarely discussed but genuinely affects examination performance in the later stages of a lengthy session.
Cognitive performance declines during sustained demanding tasks without adequate management. The strategies below are practical, evidence-informed, and can be prepared in advance rather than improvised in the moment.
Managing Your Physical State Before and During the Viva
Physical preparation for a long viva begins before you enter the room. Eat a substantial meal two to three hours before the examination — not immediately before, which can cause sluggishness, but with enough time for digestion. Avoid excessive caffeine, which initially heightens alertness but produces an energy crash after sixty to ninety minutes that often coincides with the most challenging portion of a long viva. Drink enough water before the examination to be adequately hydrated — dehydration measurably impairs cognitive performance — and ask at the start whether water is available during the session. Most examination panels will provide water if asked.
If the viva format includes a break — which is common in longer examinations — use the break to stand, stretch briefly, drink water, and take three to five deliberate slow breaths. Do not use the break to review your thesis or rehearse answers. Rest is more valuable than additional preparation at this stage.
Maintaining Analytical Quality When Fatigue Sets In
The most common sign that focus is slipping during a long viva is that answers begin to become less precise — more hedged, more circular, using more general language where specific language was available earlier in the session. If you notice this happening, use the technique of pausing deliberately before answering: “Let me think about that for a moment.” This brief, acknowledged pause gives you time to retrieve a more precise response rather than defaulting to vague language that your tired brain produces more automatically.
Maintain eye contact with the examiner who asked the question even during the pause. A candidate who looks down while pausing appears uncertain; one who maintains forward-facing attention while pausing appears to be thinking carefully. The physical act of maintaining engaged posture — sitting upright, looking forward — also has a modest activating effect on alertness, which can help sustain performance through the later stages of a long examination.
Knowing When to Ask for Clarification
In a long viva, some questions in the later stages arrive when your concentration is at its lowest. If a question is genuinely unclear — if you are not certain what the examiner is asking because fatigue has made it harder to follow — asking for clarification is entirely appropriate: “Could you clarify what aspect of the methodology you are asking about?” This is better than answering a question you misunderstood, which wastes time, demonstrates inattention, and produces a response that satisfies neither you nor the examiner. Staying focused during a long viva ultimately means managing your physical and cognitive resources deliberately from preparation through to the final question — not just enduring but remaining genuinely present throughout.
