With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order. One type of carryover effect is apracticeeffect, where participants perform a task better in later conditions because they have had a chance to practice it. Paul C.

Participants perform a task worse in later conditions because they become tired or bored. This, could lead the participant to judge the unattractive defendant more harshly because he thinks this is what he is expected to do. The biggest advantage is that exposure to different levels of the independent variable(s) cannot "contaminate" the dependent variable ("transfer" or "carry over" effects), Sometimes this is a 'must,' because you can't reverse the effects of prior exposure to other levels of the IV, Matching can reduce variability between groups, Systematically matching participants in each group for all the important extraneous variables that you think are important, Trying to reduce the variability from of individual differences, Random assignment of participants to groups eliminates bias, More resources are needed (participants, time), Less statistical power (the ability to detect an effect) because of individual difference variance, Matching takes time and effort and assumes no transfer from matching operation. Allen, M. , which means using a random process to decide which participants are tested in which conditions. The process which allows the researchers to control the ill effects of unnecessary variables in a design where participants are continuously subjected to conditions or treatments is called counterbalancing. In psychological research, a, is any intervention meant to change peoples behaviour for the better. This. The surprising result was that all participants improved in terms of both knee pain and function, and the sham surgery group improved just as much as the treatment groups.
