Using psych.function
you can fit the data of the single participant (via call of standard glm
function), estimate JND and PSE via delta method and plot the model predictions. The names of the Arguments are consistent with standard glm
and lines
function preceded by “ps.”; example ps.formula, pd.data, ps.col, etc. For the moment only works for univariable psychometric functions (lazy Italians…). See MERdemo.R and the on line tutorial for details. Write me for feedback/suggestions! 🙂
