Psychologists can utilize new technology to move the study of brain processes and behavior from the molar level of analysis to the molecular level of analysis to the micro level of analysis. The molar level of analysis examines large units of behavior such as violent behavior, sexual attraction, the work place productivity, or prejudice. The molecular level studies units of observable behavior such as playing a video game or body language. Finally the micro level of behavior is deep within the brain. Researchers use technology such as the Implicit Attitudes Test (IAT), electroencephalogram (EEG), or functional magnetic resonance imaging (fMRI) which allow neuroscientists to study cognition at the micro level.
