AP PSYCHOLOGY

Detailed explanation-1: -Replication of a research study is most likely to be facilitated by “operational definitions". An operational definition is the verbalization of operationalization utilized in characterizing the terms of a procedure expected to decide the idea of a thing or phenomenon.

Detailed explanation-2: -By having this operational definition, other psychologists are able to replicate the experiment. The operational definition lets the reader of the experiment know what was deemed a positive or negative result, thereby opening the experiment up for replication and expansion by other psychologists.

Detailed explanation-3: -It is impossible to recreate a study if we are unsure about how they defined or measured the variables. Another reason we need operational definitions is so that we can understand how generalizable the findings are.

Detailed explanation-4: -Replication is vital to psychology because studying human behavior is messy. There are numerous extraneous variables that can result in bias if researchers are not vigilant. Replication helps verify that the presence of a behavior at one point in time is not due to chance.

Detailed explanation-5: -a description of something in terms of the operations (procedures, actions, or processes) by which it could be observed and measured. For example, the operational definition of anxiety could be in terms of a test score, withdrawal from a situation, or activation of the sympathetic nervous system.
