The objective of this study is to assess whether the information received before the test has any affects on the performance in a sensomotor test, and a subsequent self-assessment of the tested person relative to the performed task. The research sample (N=90) consisted of persons at the age of 20 - 24 years (52.2% of males, 47.8% of females).
Before the test, the tested persons in particular groups received different information about the difficulty of the upcoming task. In the course of testing, the tested persons received information that the upcoming task is either difficult or very easy.
The control group received only test papers. The group of the tested persons influenced by the information about high difficulty of the upcoming task achieved best performance in the test, and these persons showed the highest values of self-assessment.
This group, however, needed the largest amount of time to fulfil the task. The group, who received information before the sensomotor test that the upcoming test will be easy, made significantly more errors, spent more time with erring, and the individuals from this group showed the lowest values of self-assessment with regard to the performed task.
Using the Kruskall-Wallis test, a statistically significant difference was found in the number of errors (p=0.0003), time spent with erring (p=0.0007), and self-assessment (p=0.0005). The results of this measurement suggest that if the probands obtain information that sensomotor tasks are difficult, they will achieve optimal performance, and their self-assessment in relation to the movement task will be higher.
