The mental rotation task is considered one of the most sex-specific tasks. Many studies suggest that the reaction time and accuracy of mental rotation may depend on other factors. The purpose of this master's thesis is to evaluate the reaction time and accuracy of mental rotation of three-dimensional bodies, which are influenced by biological, social, and emotional factors. Tasks: evaluate the effect of the MR rotation strategy for reaction time and accuracy by applying linear regression models; to identify the most frequently used strategies in groups of participants (OC, IUD, NCF, NCG, V) using correspondence analysis; evaluate the possible dependence of the reaction time of the groups (OC, IUD, NCF, NCG, V) on the conditions of the task; identify similar participants in the experiment using the cluster analysis method. Relationships of reaction time and accuracy with the chosen strategy, hormonal concentration and other social and emotional factors were studied by analyzing literature sources and the data of various questionnaires, reaction time and accuracy collected during the study using correspondence, cluster and regression analysis. It was observed that the participants who used a mixed strategy (both holistic, analytical, or other) were statistically significantly slower and less accurate than the participants who used a holistic, analytical, or other strategy (by analyzing segment directions). Also, men and subjects with an intrauterine device (IUD) chose the holistic strategy relatively more often. Subjects with a natural follicular phase of the cycle (NCF) were more likely to use all strategies. Regression analysis showed that the use of a holistic strategy was a significant variable that led women who used this strategy to be faster. Regarding reaction time, NCF and OC subjects were less dependent on task conditions than IUD and NCG women. Cluster analysis helped to identify similar study participants according to social, emotional indicators, testosterone level and the group they belong to (NCF, NCG, IUD, OC). Testosterone was a significant factor in explaining cluster formation. Participants with higher testosterone concentrations performed the MR task shorter and more accurately. . |
