USING THE COMPUTERIZED TESTS IN ASSESSING THE SIMPLE REACTION TIME OF STUDENTS IN THE UNIVERSITY "POLITEHNICA" OF BUCHAREST

The occupational profile in the technical field calls for the efficiency of the instructive-educational process by optimizing the psychomotor skills of the U.P.B. students. Through this study we aim to orientate the didactic process in the Physical Education and Sports lesson towards the specific of the engineering field. We consider it necessary to evaluate the students' simple reaction time, since this type of reaction is one of the dominant skills in this field. Consequently, we have to determine the students' current skills level, and depending on the results obtained, we will implement the operational motor structures specific to Physical Education and Sports to optimize the students' professional skills. The qualitative exploratory research aimed at identifying the reaction time to visual stimuli according to the dominant and non-dominant structure, by comparing the data obtained between genders. The number of subjects involved in the project was of 44 students (22 girls and 22 boys). The two experimental groups are randomized, made by random selection. Inquisit 5 computerized test (Computer Software) was used to evaluate the simple reaction time. Measuring the time of simple reaction to visual stimuli by computerized testing consisted of pressing the "spacebar" key at different time intervals, whenever a red circle appeared on the screen. Each subject repeated the test three times, keeping the best results. The significance test used to determine the plausibility of the hypothesis was the independent T-test (Student). The results obtained showed that there are no significant differences between the two groups with respect to the worst reaction time in the dominant and non-dominant hand (p=0.3336, t=0.9781; p=0.7646, t=0.3255). Significant differences between the girls and boys were noted for the fast reaction time in the dominant hand.

技术领域的职业能力要求通过优化U.P.B.学生的精神运动技能，提升教学过程的效能。本研究旨在将体育与运动课程的教学流程适配至工程领域的特定职业需求。我们认为有必要评估学生的简单反应时，因为这类反应是该领域的主导性技能之一。因此，我们需要明确学生当前的技能水平，并依据所得测试结果，实施适配体育与运动课程的操作性动作训练体系，以优化学生的职业技能。
本质性探索性研究旨在依据优势与非优势动作结构，识别视觉刺激下的反应时，并对比不同性别间的测试数据。本项目共纳入44名学生作为研究对象，其中女生22名、男生22名。两组实验组均通过随机抽样方式完成组建，采用随机化分组方案。
本研究采用Inquisit 5计算机化测试软件（Computer Software）评估简单反应时。计算机化测试评估视觉刺激下简单反应时的流程为：当屏幕上出现红色圆圈时，受试者需在不同时间间隔内按下"spacebar"键。每名受试者重复测试三次，取最优结果作为有效数据。
本研究采用独立样本t检验（Student检验）以验证研究假设的合理性。测试结果显示：在优势手与非优势手的最差反应时方面，两组间无显著统计学差异（p=0.3336，t=0.9781；p=0.7646，t=0.3255）。而在优势手的快速反应时方面，男女学生间存在显著统计学差异。
