In my life, I have come to experience that often people will refer back to the thing they said in the previous answer to a question with bias as to the question before. This is where the onus on the previous question, as, if they have something to hide, they will get 'defensive,' yes? On the other hand, if they are 'angry,' the opposite of 'fearful,' they will retort in a more aggressive manner, of course. This is due to them 'being sorry.' They may be sorry for the things they have done, due to wanting it not to have happened, as, now there are repercussions, and, then they will be sorry, of course. On the other hand, they might be fearful of being accused of something they have not done? This would also lead to fearful answers, full of repentance, yes? These answers will differ, if you ask them to answer quickly, and, to have honesty with yes or no at the beginning of each answer. This would be beaten by elderly people that have time to think before they answer, so, the best way to do it is to use a distraction oriented environment. This will be where they are distracted constantly, so as to get to the bottom of the question or the 'hidden emotions' behind it. Then, they could also justify this further by using a eye monitor, to see where they look, like with psychological tests? This would see the whole of the question answered by them looking somewhere as they answer, as they have little control over this, of course.
