In search of an inherent ordering of vowel phonemes, or do pilots hear like engineers do?

To test the hypothesis that formant frequencies might provide an inherent ordering scheme for vowel sounds, two groups of subjects were asked to place six Italian vowel phonemes (A, O, U, AE, E, and I) into the most musically pleasing order. A subsequent chi 2 analysis of selections of the first group (21 music students and engineers) indicated a reliable consistency in vowel order supporting the hypothesis. Analysis of the second group (12 pilots) did not indicate any consistent ordering.

Curve negotiation performance in a driving simulator as a function of curve geometry.

A study was conducted to investigate driver performance on curves. The between-trial factors were Blood Alcohol Content (BAC) level (0.00, 0.

Effects of pyridostigmine bromide on in-flight aircrew performance.

The effects of a chemical defense pretreatment drug, pyridostigmine bromide (PB), on in-flight aircrew performance were assessed using the Total In-Flight Simulator (TIFS) aircraft. TIFS was used to supply appropriate control dynamics, handling characteristics, and cockpit instrumentation for a tactical transport airdrop simulation. Twenty-one C-130 pilots flew two familiarization and four data flights.
