RESUMO:

Introduction: Attention is considered a psychological process that supports all cognition. To measure attention in a natural learning context (classroom), using objective and non-invasive methods, easy to use and with scientific rigor, to understand how it behaves over time and how it is modulated from the individual characteristics of the students, has become a challenge for teachers and researchers. Today it is known that the Sustained Attention (SA) can be measured by autonomic activity of Heart Rate Variability (HRV). Objectives: To design and validate an SA detection system from HRV (ADS-VHR1). To detect HRV behavior from time, frequency and non-linear measurements domains, throughout 60 minutes of classes in class room. To verify if the SA can be modulated by individuals Personality characteristics, Emotion and Chronotype in University students. Method: 12 systems ADS-VHR1 were validated using long segments with heart pulse recordings in a time no longer than 10 minutes, paired to a standard system, in a simple random sample, with three male volunteers. Subsequently, the Cardiac Pulses were recorded in a time of 60 minutes during 4 sessions of classes in a sample of 30 Nursing and Physiotherapy undergraduate students, with an average age of 25 ± 6,951. Subsequently, using a nonparametric procedure, it was verified how students psychological structure modulates the SA in classroom. Results: In the exploratory analysis for the validation of the, a Cross-Correlation Coefficient of r=0.569 to r=0.996; an Intraclass Cross-correlation of CCI=0.605 to CCI=0.998 and a Cronbach's Alpha of α=0.61 to α=0.99. The correspondence between the paired systems is confirmed by an analysis of variance. On the other hand, there were significant differences in HRV in the time series in the 60-minute window, in all its parameters (Time domain, Frequency and non-linear measurements), with a systematic reduction of heart rate to from the first 15 minutes until the end of classes. At the same time, there was no significant intra-group difference in any psychological measure associated with HRV. However, for Chronotype, in the 40th minute there is a difference with respect to the High Frequency band [χ²=9,853(3), p=0,020] and there is a significant difference between the Vespertino and Matutino groups [H=-20,1 (DV=-2.73), p=0.038]. Conclusions: The validity and reliability of ADS-VHR1 is demonstrated for what it was designed. It is concluded that the time of attention sustained in the university students has an important physiological activation in the first 15 minutes of a class. It was also verified that the Chronotype modulates, although in a diffuse way, the Sustained Attention in the university students in the classroom. It is recommended to continue with the studies.
