Disclosed systems and methods analyze a complex auditory response to generate a particular model for a behavioral outcome. An example method includes analyzing one or more response to a complex stimulus to identify regions in each response and peaks in each region. The example method includes constructing a behavioral outcome model based on region and peak information by evaluating a plurality of parameters based on the information associated with the regions and peaks and applying a best fit analysis to include and/or exclude parameters from the plurality of parameters to determine parameters and relationship between the parameters to form the model. The example method includes facilitating application of the model to generate a score by obtaining values for the parameters forming the model and combining the values according to the relationship between the parameters specified in the model, the score indicative of the behavior outcome with respect to at least one first subject.
