Abstract

Objectives: This research was conducted in order to determine the influence of thermal comfort, as measured by the index of temperature Wet bulb globe temperature (WBGT), the Global Attention and Perception Index (GIFS) of high school students from a school in Barranquilla, Colombia. Methods/Statistical Analysis: For this, an experimental design was performed, in which the variable peck response was the GIFS, the potential factor was the WBGT, whose levels were the records under different environmental conditions, and the disturbing factor controllable was “student”, this last it was blocked to minimize variability that this could introduce in response, thus obtaining a completely random model blocks. Subsequently, a group of tenth and eleventh grade other selected, subjected to different environmental conditions for 6 days, in which we applied the Toulouse-Pieron test, to measure attention and concentration; and a survey based on the McIntyre scale to evaluate thermal satisfaction, while thermal comfort was measured using a heat stress monitor. Findings: The collected data were processed statistically using analysis of variance, to see if there were differences between levels, and if the data came from a normal distribution, correlation analysis to determine the influence of WBGT factor in the response variable GIFS and descriptive techniques as bar charts, box and whisker plot, among others, which allowed characterizing the information and identify trends. Application/Improvements: The results showed values of WBGT index mostly within the TLV’s; an inverse strong correlation of 90% between the two variables for the sample taken from tenth grade and a moderately strong relationship of 64.9% for eleventh grade, showing greater influence of environmental conditions on the rate of attention and concentration and thermal student satisfaction in the first group compared to the second, who apparently are less sensitive to these.
