Proposed in Misyak et al. (2010) as a way to study online learning of probabilistic sequences, the SRT paradigm tracks participants' reaction time to sequential audio stimuli.
Audio recordings of target words are played (e.g., the nonwords ral, baf, tus), and participants must click on each of them in the grid while avoiding the foil words (e.g., dut, vad, and zug).
See this plugin, audio-button-response-grid, in action by opening index.html in a browser.
The experiment code can be found in exp.js.
This code illustrates a 2x3 grid (as in the original study of three-word non-adjacent dependencies) as well as a 2x2 grid.
audio-button-response-grid has the usual parameters of jsPsych's existing audio-button-response plugin (see its documentation here), with the addition of:
rows: Integer, the number of rows the grid should have.columns: Integer, the number of columns the grid should have.
The grid is based on the html-button-response-grid plugin created by Aislinn Keogh that can be found here.
