Two days later, participants returned to the lab and did the same task.
#Auditory imagery series#
A different series of experiments asked participants to imagine a particular melody and then to hum the starting pitch of the melody they were thinking about. Participants’ performance was better when the tone they were trying to detect was the same pitch as the one they were imagining-suggesting both that the image had accurately represented the pitch and that this imagined pitch primed the processes of actual hearing. One series of experiments, for example, asked participants to imagine a specific pitch, and then to detect a faint tone either of the same pitch or different. One line of research has sought to confirm the subjective sense that auditory images do directly represent a sound’s pitch. Research on auditory imagery has taken several different paths. This entry describes imagined pitch, duration, and timbre differences between sounds and auditory images enacted auditory images the neural substrate of auditory imagery and memory for enormously familiar sounds.
Functionally, the image seems to provide direct information about these attributes, suggesting that the image truly does depict the sound, rather than merely describing or referring to the sound. Subjectively, the imagined sound seems to have a clear pitch, duration, and timbre, just as an actual sound would. Nonetheless, the experience of “hearing” the imagined sound does resemble the experience of hearing an actual sound. Auditory images are not hallucinations-people experiencing the images can tell that the images are “in their head,” and not a real sound.
