Abstract

This study explores the relationship between hemispheric dominance and cognitive performance among 50 undergraduate students at UNA Puno. Using the Ned Herrmann Brain Dominance Instrument (HBDI), students were categorized into four dominance types. Multivariate analysis showed significant correlations between hemispheric dominance and cognitive tasks (r = 0.87 for left and r = 0.85 for right hemisphere, p < 0.001). Regression analysis revealed the effects of left hemisphere dominance on logical tasks (β = 0.62) and right hemisphere dominance on emotional/creative tasks (β = 0.53, p < 0.001). Latent class analysis identified three cognitive profiles: Left Dominant (41%), Right Dominant (36%), and Balanced Dominant (23%). Deep learning models showed 94% accuracy and AUC of 0.97.
