How to test whether a person is Left-Eared or Right-Eared? It is well-known that the majority of humans have left-right preferences when using their hands or feet. But it is perhaps less well-known that the same can be true for our eyes and ears.

I once heard of a simple test to check whether I was left-eyed or right-eyed. In a room, quickly turn your head to look up to a corner where the ceiling meets the two walls. Then close each eye in turn, and you should find that only one eye is aimed straight at the corner.

I have no idea how reliable this test is, or how strongly people tend to prefer one eye to the other. But assuming there's something in it, I wonder whether anyone knows of (or can devise) a similarly simple test for the ears?
The Lateral Preference Inventory

Coren (1993) developed an inventory  for lateral preference (The Lateral Preference Inventory). Several items concerned ear preference.

I found the choice of items to be quite interesting. See below for the items concerned with ear preference. 



Based on a large adult normative sample, a total score was created for the four items above (+1 for right; -1 for left; 0 for either)



Ear preference tasks

This is not my area, but I did a quick search on Google Scholar and found an article by Noonan and Axelrod (1981) where they discuss behavioural measures of ear preference.


  A total of 373 normal young adult subjects were distributed among 5
  experiments measuring earedness. Handedness, eyedness and familial
  L-handedness were also indexed. Special care was taken to remove
  environmental asymmetries when determining ear preference when
  listening to sound from a suspended earphone, and from a stopwatch on
  a table, and for using a telephone symmetrically constructed and
  displayed. Ear preference was strongly influenced by seemingly minor
  environmental asymmetries and did not influence telephone habits, and
  must be considered a very weak lateral preference. Earedness was as
  concordant with handedness as eyedness was found to be; earedness was
  concordant with handedness in 74% of dextrals and 65% of sinistrals,
  but earedness was not related to eyedness. Earedness did not vary with
  putatively hemisphere-specific stimulus types (music, speech).
  Laterality of telephone use was jointly determined by handedness and
  the expectation of writing, not by earedness.
