Echophenomenon (also known as echo phenomenon; from Ancient Greek ἠχώ (ēkhṓ) "echo, reflected sound") is "automatic imitative actions without explicit awareness" [1] or pathological repetitions of external stimuli or activities, actions, sounds, or phrases, indicative of an underlying disorder.
Echolalia is common in young children who are first learning to speak. Echolalia is a form of imitation. Imitation is a useful, normal and necessary component of social learning : imitative learning occurs when the "observer acquires new behaviors through imitation" and mimicry or automatic imitation occurs when a "reenacted behavior is based ...
Echopraxia is a typical symptom of Tourette syndrome but causes are not well elucidated. [1]Frontal lobe animation. One theoretical cause subject to ongoing debate surrounds the role of the mirror neuron system (MNS), a group of neurons in the inferior frontal gyrus (F5 region) of the brain that may influence imitative behaviors, [1] but no widely accepted neural or computational models have ...

Those who can see their environments often do not readily perceive echoes from nearby objects, due to an echo suppression phenomenon brought on by the precedence effect. However, with training, sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability. [9]
Following Sperling's (1960) procedures on iconic memory tasks, future researchers were interested in testing the same phenomenon for the auditory sensory store. Echoic memory is measured by behavioural tasks where participants are asked to repeat a sequence of tones, words, or syllables that were presented to them, usually requiring attention ...
I heard the usual echo which goes round the Earth with an interval of about 1/7 of a second as well as a weaker echo about three seconds after the principal echo had gone. When the principal signal was especially strong, I suppose the amplitude for the last echo three seconds later, lay between 1/10 and 1/20 of the principal signal in strength.
