One of the big problems, when it comes to making a decision, is to know which is the best alternative.
The more important the matter to be treated or the less time it takes to respond, the more "difficult" it seems to be to assume the "right answer."
Although in real life, there is no single alternative, nor is it clear which is more correct among the various options, so the level of anxiety that can generate can get to block the person.
A typical case is that of the students, when faced with a test, where not only is evaluating the level of knowledge acquired by the same but self-control, and tolerance to stress of the student.
Because a student, however well prepared he is, if he has too high a level of stress can block him and prevent proper performance, but how does this occur?
This is what has been tried to respond with a research conducted from the Faculty of Psychology, University of Leiden and the Institute of Brain and Cognition (Netherlands) together with the Faculty of Psychology, German University of Sport of Cologne whose Results have been published in February 2019 in the scientific journal Plos One.
Eighty six women were randomly assigned to a group in which stress would be induced prior to a task through the Leiden Performance Anxiety stress Procedure (L-PAST), remaining in the control group, which would not have the Social and temporal pressure to generate additional stress to the test.
The results show how to higher levels of stress induced worse execution in the task of working memory, being this effect greater, when also the people more sensitive to the stress against the less sensitive.
In other words, the effect of anxiety and therefore its interference in the execution of tasks depends on both an external stressing component and the greater or lesser sensitivity to the stress of the person.
So, and going back to the example above, the student who has a stress-sensitive trait, that is, to be nervous with a little stress, will be at a disadvantage with respect to his companions when responding adequately to an exam.
In other words, at the same level of elevated external stress given by the evaluation test, the most sensitive ones will also live the situation as more threatening and with it, their execution and at the end, their qualification may be less than their actual level of learning.
This can lead to certain students, sensitive to stress, to be shown as "bad students", by not getting good grades as much as they strive to study.
Hence the importance of being able to incorporate relaxation practices prior to exercises and evaluations, thereby reducing the level of sense stress and with it, that can show what you really know.
