Document Summary
This is where some sequences produce effects that are different from those produced by other sequences (order). Positive transfer of learning: you figured out something about puzzle a that makes it easier to do puzzle b. But when people start off doing puzzle b first they don"t get the advantage of the above so they do not get a positive transfer. If you have her asymmetric then counterbalancing ill not solve the problem. Control problems in developmental research: longitudinal study is similar to a within subject design since one person is tested over. In developmental research h is typically the independent variable. many years of their existence. The disadvantage is the amount of time to complete makes it seem impractical. Could get order effects, practice effects because they are being tested over and over again, can even get subject attrition(dropout). The environment may act as a confounding variable since one cannot be separated from the other.
