To be more sure we replicate studies, which means that the study is conducted again in the same way but using different participants. A replication study in which researchers repeat the original study as closely as possible to see whether the original effect shows up in the newly collected data. May use an exact duplicate of an experiment or an alternative procedure, or completely different techniques may be used to try to gather theoretical information. Conceptual replication is key: Conceptual replication. What does conceptual replication mean in psychology? In this project, 100 studies were replicated by independent investigators.

Conceptual replications, by contrast, deliberately modify the critical elements of an original procedure in order to test the robustness of a phenomenon or the generality of a theoretical claim. An operational definition allows the researchers to describe in a specific way what they mean when they use a certain term. Should psychologists prefer direct replications, which attempt to recreate the original procedures of a study as exactly as possible, or conceptual replications, which attempt to manipulate the theoretical variables in an experiment in novel ways? University of Utah, University of Virginia, Portland State University. In addition, specific task variables are often necessarily changed as well. Replication with new data and with a new or revised research protocol16: new data collection with a different design from the original study in which the research question remains unchanged compared to that of the original study (often referred to as a "conceptual replication").17 An advantage of the above definition of "replication Conceptual replication generally refers to cases where researchers 'tweak' the methods of previous studies [] and when successful, may be informative with regard to the boundaries and possible moderators of an effect.When a conceptual replication fails, however, fewer clear implications exist for the original study because . 1 .
