Evolution of the brain dominance profile according to Herrmann quadrants in second year students of the University of Antofagasta medicine

Abstract

The objective of the study was to compare the evolution of Herrmann's brain quadrants in second-year medical students in the 2020 period, with the measurement carried out in this group during 2019. Regarding the methodology, a longitudinal study was developed quantitative - descriptive. The research design is non-experimental. It considered as a sample 50 students out of a total of 54 who attended the IV semester of the study plan of the Medicine career during 2020 and who participated in the study carried out in 2019, which makes up the inclusion criteria. As exclusion criterion, students who have failed the Introduction to Medicine course taken in 2019 were considered. The information collection instrument applied was a questionnaire. The study was approved by the Ethics and Scientific Research Committee of the University of Antofagasta. Regarding the results, the prevalence of the same information processing styles with respect to the 2019 study is confirmed. Those that register increases in 2020 are: right cortical quadrant (from 30% to 33%); and left limbic (from 28% to 29%). In conclusion, the brain quadrants maintain their stability with respect to the previous measurement (2019), complying with what is established in the literature regarding their little variability after a short period of time elapses.
