Alternative explanations for procedural effects on magnitude-estimation exponents for taste, invoking adaptation, context, and volume effects.
Taste adaptation to residual stimuli from prior tastings was considered along with context and volume effects. These factors are proposed as alternative or supplemental explanations for the differences in the magnitude-estimation exponent (slope of the log-log plot of taste intensity versus solute concentration) that have been obtained by various workers using different stimulus presentation procedures.
