Document Summary

Measures the extent to which research indings can be generalized to: other paricipants/populaions, seings, ways of measuring variables. Extent to which relaionships among conceptual variables can be demonstrated in: a wide variety of people, a wide variety of operaional deiniions (manipulated or measured variables) Across seings: the uniqueness of an experiment makes it possible that the indings are limited to the speciic. The efects of violent television on aggression: manipulaing violent television diferently. The efects of rewards on moivaion: measuring moivaion diferently, repeat an experiment. Diferent operaionalisaions of the variables: increase the potenial generalizaion by increasing ecological validity. The research is conducted in situaions that are similar to the everyday life experiences of the paricipants. The four general types of replicaion: exact replicaion. Repeat previous research design as exactly as possible. See if an efect found in one laboratory or by one researcher can be found in another lab by another researcher: conceptual replicaions.
