evaluated using alcohol challenges where, on rising, peak and falling BACs (peak BAC averaged about 60 mg/dl), they reported subjective feelings of intoxication, and were evaluated for changes in standing steadiness (body sway), and, depending on the specific paradigm, the research team recorded physiological measures (e.g., blood cortisol, background electroencephalograms, event related potentials) ( Ehlers et al.,1999; Schuckit and Gold, 1988; Schuckit et al., 1988).
