![]() And third, measures should be responded to consistently, both within items designed to measure a specific construct and over time in response to a consistent stimulus. Second, measures should successfully capture the intended and not unintended constructs. As applied to HRI, a general measure of social responses to robots should identify and capture what people spontaneously focus on when they think about, look at, or interact with a robot. First, an instrument should be capturing what it purports to be measuring. Several goals are important in developing a psychometrically sound testing instrument. As such, we can look to psychometrics to assess measures used in HRI and to guide further development and refinement. As we argued earlier in this chapter, social reactions to robots are central in accounting for various important aspects of HRI. Psychometrics provides researchers with a set of standards by which to judge the effectiveness and likely success of measuring psychological phenomena. Psychometrics is a field of study focused on the theories and techniques involved in measuring psychological constructs.
