    Fasting might affect attentional processes; however, its effects on quantitative electroencephalographic activity (qEEG) remain unclear. We used an n-back task to assess the effects of an 18-hour fasting period on behavior and qEEG absolute power. Twenty-six participants performed the experimental task with two cognitive load levels during fasting and regular breakfast in different sessions. Artifact-free epochs were selected for further analysis between conditions. The higher cognitive load affected accuracy, which decreased, while frontal and parietal theta power increased. We also found greater absolute theta power magnitudes for the left-frontocentral locations and a significant interaction between cognitive load and recording site, reflecting the greater increase in left-central parietal locations. Alpha increased in left-frontocentral locations. Although fasting did not considerably vary EEG power, there was a relevant fasting-related increase in theta power over frontal areas, probably reflecting transient changes in cognitive control mechanisms.

    ¿Es el esfuerzo una característica esencial de la voluntad? Una aproximación a William James desde la psicología de Tomás de Aquino
    (2018)
    Tellez-Maqueo, David-Ezequiel
    William James puts forth the feeling of effort as an essential feature of the mil ¿n such a way that its presence would be an undeniable sign of a voluntary act, and its absence proves that the mil is missing. This historically accepted consideration has contributed to the prevailing assumption that the power of will depends on the more or less effort to execute an act: the more effort one puts into operation, the more will one have. The purpose of this article is to show a consideration of the will according to these terms disagree with Thomas Aquinas's vision, who teaches that there are voluntary actions that don't take hard work. As a result of the aquinian stance, the common belief that the most valuable actions are the most difficult ends up being disputable. © Veritas
