5.2.1. Influence of VR Features  
Regarding VR variables, the results show that navigation variables, which are related to the movements of the subject in the virtual environment, seem to be more meaningful in risky zones; while interaction variables, which are related to the interactions of the subjects with the different elements of the virtual environment (buttons and virtual elements), seem to be more relevant in no risk zones. Results of the presence questionnaires are similar, or even better, to those obtained in other works [90,91]. Starting with the navigation variables in risk zone, the results show that the time spent in risk zone has a strong influence on the prediction of variables of personality, impulsivity and sensation seeking. Longer time spent in a risk zone could mean either that the subject has passed through these areas slower, or that (s)he has passed through them a greater number of times. In any case, this may be related to the higher/lower susceptibility to punishment or to negative consequences. The neuroticism and negative urgency variables, in which time spent in risk zone appears as important predictor, are related to the sensitivity to punishment or to negative stimuli [15,32], so this would explain the relationship with the time spent in risk zone in our virtual environment. On the other hand, it also appears as important for the classification of the subjects in thrill and adventure seeking and positive urgency variables, together with the number of visits to each risk. In these cases, it is possible that subjects with greater interest in risky physical activities or with impulsive behaviors when facing situations perceived as positive decide to experiment and spend more time in these risk areas, to see what the consequences are. The variable of distance covered in risk zone refers to the length of the subject's trajectory in the risk zones of the maze. This variable appears as important in the classification of the subjects in the variables of thrill and adventure seeking and disinhibition, both belonging to the dimension of sensation seeking. This variable was also measured in the previous version of AEMIN [58], and significant correlations were obtained with almost all sensation seeking subdimensions, so our results in both articles seem to be consistent. Covering a greater distance in AEMIN could be interpreted as a greater interest in exploring different areas of the maze, which could be related to the variables thrill and adventure seeking and disinhibition, since both of them are reflected in high engagement in activities that generate new sensations and in rule-breaking behaviors [21]. Velocity and acceleration in risk zones appear as important variables in predicting lack of premeditation, experience seeking, and disinhibition. The action of quickly passing through the risk areas, without stopping to pick up spheres could have a double interpretation. On the one hand, it can be understood as an unpremeditated or risky action. Instead, it could also be interpreted as an intention to pass something bad as quickly as possible, avoiding the possible damage that could be caused by passing through a risk area. As for the interaction variables in risk zones, the number of green spheres collected in risk zones helps to classify subjects into extraversion and thrill and adventure seeking subdimensions. Picking up spheres that are in risk areas can pose a risk, since the subject must pass through these areas without the protection of the shield to pick them up. Therefore, the decision to take a sphere that is in a risk zone may be related to excitement seeking--which is characterized by an interest for shinny colors and noisy environments [92] --a common feature of the extraversion and thrill and adventure seeking dimensions [93]. The use of the shield only influences in risk zones, to classify subjects in terms of boredom susceptibility.
