Reflective listening is an active listening technique by which the listener indicates to the speaker that he is listening to her. This can involve more passive reflection by means of small verbal interjections and facial expressions, or it can involve deeper clarification by means of repeating or paraphrasing the speaker.
Passive reflection is a more useful technique for encouraging the speaker to share everything she has to say. This is primarily accomplished by vocalizations like "yes," "no," "oh," "OK" and "mhm." Body language and facial expressions also contribute to passive reflection. Leaning forward to show interest, frowning when upsetting information is conveyed and laughing in response to jokes or amusing situations are all examples of passive reflection.
Clarifying reflection is a more useful technique in a school or work environment when some sort of task must be accomplished. This is verbal and usually accomplished by repeating the speaker's words to her to assure the listener he has heard what she was attempting to convey. This can be done by directly repeating the speakers words back to her or by paraphrasing the speaker's words to convey what the listener thinks she said. It is usually not advisable to add further ideas to what the speaker is saying, but it is advisable to ask which of previously-addressed topics she is referring to if the listener is uncertain which she means.
