Generate stimuli and analyze data of reverse correlation image classification experiments (psychophysical tasks aimed at visualizing cognitive mental representations of faces). For the method see Dotsch and Todorov (2012) doi:10.1177/1948550611430272 ; for a practical primer see Brinkman, Todorov and Dotsch (2017) doi:10.1080/10463283.2017.1381469 .
Details
vignette("reverse-correlation-walkthrough", package = "rcicr") works through a complete
experiment. In brief: generateStimuli2IFC creates the stimuli and the
.Rdata file recording how they were made, and generateCI or
batchGenerateCI turns participants' responses into classification images.
vignette("getting-started", package = "rcicr") is the shortest working example;
vignette("recipes", package = "rcicr") answers questions that come up after the basics;
vignette("stored-data", package = "rcicr") lists everything in the .Rdata file and in a
returned classification image.
citation("rcicr") prints the reference for the software; cite the method papers
below as well.
