Discrimination of musical notes by women and men after acute alcohol consumption.

Abstract

This study compared young adult men and women regarding the discrimination of musical notes following acute ingestion of alcohol. It included 20 men and 20 women aged 18 -30 years (women: M ϭ 21.95, SD ϭ 3.14; men: M ϭ 21.65, SD ϭ 2.73). This was a discrimination test of musical notes through the psychophysical forced-choice method, in which participants had to choose between two alternatives: the musical note that contained the sound frequency related to note D, F, or A, after the presentation of a standard sound frequency. The results showed significant differences between groups when comparing men and women after the ingestion of alcohol only in the D note. We found also significant differences in the comparison group of women under the influence of alcohol with each other, in the D note, and the group of men under the influence of alcohol among themselves in the F note. These results suggest that acute alcohol ingestion can change the auditory perception of men and women regarding discriminating specific musical notes (sound frequencies).

Funcionamiento neuropsicológico en profesionales jóvenes que consumen alcohol como actividad de esparcimiento

“…Diversas investigaciones que han realizado comparaciones entre sujetos que consumen alcohol y sujetos controles, han encontrado que los individuos que consumen esta sustancia presentan alteraciones en su funcionamiento neuropsicológico, presentando menor desempeño en tareas neuropsicológicas que valoran la atención, memoria, solución de problemas complejos, procesamiento de la información, habilidad viso-espacial, habilidades lingüísticas, aprendizaje, discriminación auditiva, velocidad motora y funciones ejecutivas. Estos resultados han permitido identificar al consumo de alcohol como un factor de riesgo que atenta en el adecuado funcionamiento cerebral del ser humano (Boelema et al, 2016;Brown, Tapert, Granholm, & Delis, 2000;Day, Celio, Lisman, Johansen, & Spear, 2013;Ferrett, Carey, Thomas, Tapert, & Fein, 2010;Montgomery, Fisk, Murphy, Ryland, & Hilton, 2012;Silva et al, 2017;Stavro, Pelletier, & Potvin, 2013;Thoma et al, 2011).…”
