Research project Interval sequences represent the time intervals between beats, when a person tries to beat a steady pulse. Various aspects of variability in interval sequences are found to correlate with cognitive performance and with neuroanatomical properties of the brain.
Human timing performance is a highly significant aspect of our psychological functioning. Like many other attempts to measure psychological constructs, the use of different methods and instruments incur unwanted error variability that reduces reliability. Also, specific choices of methods may be based on more or less correct or relevant theory, which raises issues of validity: What are we actually measuring? We will therefore systematically compare a number of different data collection and analysis methods with respect to the reliability of serial isochronous serial interval data from human participants.
