Validity refers to whether a measure actually measures what it is intended to measure. If the measurement of smiling or laughing during a movie does not actually indicate level of happiness, then the data gathered from it would not be considered valid. Reliability refers to the consistency of a measure, systematic refers to the organization of data, and event related refers to data collected from a specific event or time frame. While these are important concepts in research, they do not directly relate to the issue of validity in this scenario.
