What can affect reliability in research?
It depends on the nature of the measurement (e.g., focus/attention affects reaction times, hunger/tiredness leads to reduced physical/mental performance, etc.). These participant changes can create error that reduces the reliability (i.e., consistency or stability) of measurements.
