Editing Atkinson–Shiffrin memory model (section)

===Echoic memory===
[[Echoic memory]], coined by [[Ulric Neisser]],<ref name=Neisser1967 /> refers to information that is registered by the [[auditory system]]. As with [[iconic memory]], echoic memory only holds superficial aspects of sound (e.g. pitch, tempo, or rhythm) and it has a nearly limitless capacity.<ref name=DarwinTurveyCrowder1972 /> Echoic memory is generally cited as having a duration of between 1.5 and 5 seconds depending on context<ref name=DarwinTurveyCrowder1972 /><ref name=Treisman1964 /><ref name=Norman1969 /> but has been shown to last up to 20 seconds in the absence of competing information.<ref name=GlucksbergCowen1970 />
