Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.
A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychologists attempt to understand the role of mental functions in individual and social behavior. Others explore the physiological and neurobiological processes that underlie cognitive functions and behaviors.
Psychologists are involved in research on perception, cognition, attention, emotion, intelligence, subjective experiences, motivation, brain functioning, and personality. Psychologists' interests extend to interpersonal relationships, psychological resilience, family resilience, and other areas within social psychology. They also consider the unconscious mind. Research psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. Some, but not all, clinical and counseling psychologists rely on symbolic interpretation. (Full article...)

The denomination effect is a form of cognitive bias relating to currency, suggesting people may be less likely to spend larger currency denominations than their equivalent value in smaller denominations. It was proposed by Priya Raghubir, professor at the New York University Stern School of Business, and Joydeep Srivastava, professor at University of Maryland, in their 2009 paper "Denomination Effect".
Raghubir and Srivastava conducted three studies in their research on the denomination effect; their findings suggested people may be more likely to spend money represented by smaller denominations and that consumers may prefer to receive money in a large denomination when there is a need to control spending. The denomination effect can occur when large denominations are perceived as less exchangeable than smaller denominations. (Full article...)

Selected biography -
Aron Keith Barbey (born January 6, 1977) is an American cognitive neuroscientist, who investigates the neural architecture of human intelligence and brain plasticity. Barbey is the Emanuel Donchin Professorial Scholar of Psychology and a Professor of Psychology, Neuroscience, and Bioengineering at the University of Illinois. He is director of the Decision Neuroscience Laboratory at the Beckman Institute for Advanced Science and Technology, and founding director of the Center for Brain Plasticity at the Beckman Institute, where he leads the Intelligence, Learning, and Plasticity (ILP) Initiative.
He has used both classical lesion methods and functional magnetic resonance imaging (fMRI) techniques to better understand neural architecture and its relationship to intelligence. Barbey used lesion mapping to study Vietnam veterans who had suffered brain trauma. He was able to record diagnostic images of their brains and relate this anatomical data to their documented problems, creating a "brain atlas" linking cognitive functions to neural organization. He has suggested a framework called “structured event complex theory” that describes the inferential architecture of the prefrontal cortex. (Full article...)
