Detailed explanation-1: -A carryover effect is an effect of being tested in one condition on participants’ behaviour in later conditions. One type of carryover effect is a practice effect, where participants perform a task better in later conditions because they have had a chance to practice it.
Detailed explanation-2: -The independent variable refers to the variable in research that is manipulated or varied by the researcher to create an effect. It is so-called independent since these are variables of the study that causes the effect measured in the research.
Detailed explanation-3: -What type of experimental design is affected by order effects? What can researchers do to address order effects and how does this fix them? Counterbalancing addresses order effects by varying the order in which the levels of the independent variable are presented to the participants.
Detailed explanation-4: -Single-subject experimental design: A research method in which a single subject is observed and measured both before and after the manipulation of an independent variable.
