Statistical structure in rapid sound sequences - Part 2 and 3

Task requiring the detection of deviant tones in different types of probablistic sequences.

CS_MainExperiment

Built with Experiment

In this experiment, a frequency deviant is embedded in a sequence of either randomly order tones or tones that a pattern generated using a Community Structure. Three different walks are used to generate the Community Structure, a Unrestricted, Eulerian or Hamiltonian walk. Participants are randomised to only be given sequences from one walk. For more details see experiment 2 in Milne et al.

Built with Experiment

In this experiment, the frequency deviant is either placed within a community structure or at a community boundary. See Experiment 3 in Milne et al. for more details.
