On the psychometric function for contrast detection

The frequent current use in probability summation calculations of equations of the form. P = 1 − (1−γ)exp[−(I/α) β] to represent the psychometric function for contrast detection is based on two assumptions: (1) γ can be changed without affecting α and β (the high-threshold assumption) and (2) β is t...
