Social psychology is an active and vibrant discipline.
One indicator of progress is the rapid proliferation of new methodologies, statistical procedures, and other tools that support and enhance research. Examples include structural equation modeling, categorical data analysis, meta-analysis, spectral analysis, treatment of interdependent data, and so on. Other methodological and theoretical approaches have exploded on the scene for which very little expertise or skill exists among most social psychologists. Examples include psychophysiological and neuropsychological measurement, internet-based research, experience sampling methodology, and applications of chaos theory and nonlinear dynamical systems theory. Still further opportunities exist for social psychologists to acquire the skills, methods, or theories of other disciplines thereby enabling or facilitating cross-disciplinary collaborations.
