#### 3.1.1 Descriptive Analysis  
The parameters examined included net attention (A-E), impulsivity control index (ICI) and figurative creativity. Descriptive statistics for the experimental cohort are presented in Table 4, while Table 5 contains the data for the control cohort. For the experimental group, the aggregated data from the three experimental conditions have been categorised according to the different coloured light scenarios. Similarly, for the two existing control groups, the data were organised in a comparable way in relation to the two applicable experimental conditions. All tables present the sample size ('n') for each dimension assessed in the various lighting scenarios. Each lighting scenario is associated with a different day, as outlined in the methodological framework. The experimental group shows elevated A-E and ICI values in almost all coloured light scenarios, in contrast to the daylight condition. When juxtaposed with the results of the control group on a daily basis, the experimental group's net attention is significantly lower in the daylight condition; conversely, it is higher in the orange and purple scenarios compared to the control group's daylight condition. This trend does not extend to the ICI, \begin{table}

Table 5: Descriptive values of net attention, impulsivity control and figurative creativity in the different control light scenarios. where the experimental group's values remain systematically lower, with the exception of the median of the purple scenario, which exceeds that of the control group. In terms of figurative creativity (and most of its component dimensions), the experimental group also shows high values in all colour scenario assessments relative to the natural condition.
