Pregunta 2

Pregunta
Give an example of research into top-down processing of auditory stimuli and what was found.
Respuesta
  • Miller and Licklider (1950) recordings of word lists regularly interrupted, words perceived more natural when interrupted by noise, then when interrupted by silence (picket fence effect)
