El Efecto “Cocktail Party” se refiere al fenómeno psicológico de atención que describe cómo en un lugar público con varios sonidos, podemos prestar más atención a una plática o ruído.
The cocktail party effect refers to a phenomenon of auditory attention, describing the ability to focus one’s attention on a particular stimulus while filtering out a range of other stimuli, much the same way that a partygoer can focus on a single conversation in a noisy room. This effect is what allows most people to “tune in” to a single voice and “tune out” all others, and is thus referred to as a theory of selective attention. It may also describe a similar phenomenon that occurs when one can immediately detect words of importance originating from unattended stimuli, for instance hearing one’s name in another conversation.
