Stimuli, Trials and Sampling

Most tasks on Meadows involve stimuli: media or text objects that you want the participant to respond to or interact with. These are organized as a Stimulus Set. Here's the types of stimuli you can use:

  • Images .png or .jpg files.
  • Audio .wav, mp3 or .flac files.
  • Video .mp4 or .ogv files.
  • Text stimuli words or sentences

For each task in your experiment, choose which stimuli to include in the Stimuli tab of the task. Here you can select a subset or customize the stimuli. The task logic then chooses how to divide the selected stimuli across trials (but some tasks may just consist of a single trial). If you want to override the trial sampling, you can use a Trial File.
