CDFs for subjects in the present study, who responded to MSG, citral, and the incongruent mixture of MSG + citral. (A) The pooled CDF obtained for the MSG–citral mixture (M-C_Obs, filled circles); the CDF predicted from a model of stochastic independence (probability summation model: M-C_Pred, open circles); the CDF for the MSG alone (M, open squares); the CDF for citral (C, open triangles); and the CDF for false positive responses to water (FP, open diamonds). (B) CDFs to the MSG–citral mixture for each of the 11 individuals subjects. Black and gray lines represent observed and predicted CDFs, respectively. (C) Predicted (open circles) and observed (filled circles) CDFs over a linear portion of the pooled distribution of RTs to the mixture, before correcting (gray) and after correcting (black) for false positive responding. Values on the abscissa are given as log RT (seconds).
