  L-handedness were also indexed. Special care was taken to remove
  environmental asymmetries when <strong>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.</strong> <strong>Ear preference</strong> was strongly influenced by seemingly minor
  environmental asymmetries and did not influence telephone habits, and
  <strong>must be considered a very weak lateral preference</strong>. 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.</p>

I don't think the Cohen inventory is useful, because the tasks are far too strongly influenced by handedness and footedness (i.e. reaching for, or leaning towards, an object), and they do not measure behaviour directly. The Noonan/Axelrod paper is far more useful, and it confirmed all of my hunches. But, sadly, it does not answer my question. Rather it seems to undermine my question, by highlighting the difficulty of eliminating environmental influences, and/or other lateral preferences. Earedness seems to be a quite weak preference, and so a simple self-test might not be possible.

@ekhumoro That sounds like a good synopsis. I imagine there's more research out there. Perhaps check out https://scholar.google.com/scholar?q=earedness

To which ear do you hold your phone? Or is that a test of handedness?

@ArtemKaznatcheev. My hunch would be that hand preference is generally stronger than ear preference, so it might not be an effective test. Having said that, if a right-handed person is forced to pick up the phone with their *left* hand, do they still try to hold it to their *right* ear? I've certainly seen lots of people do that, and I'm sure I do it myself - but is that really evidence of earedness, or just ingrained habits?
