Psychology is the study of mind and behavior in humans and non-humans. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. 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.
The hard–easy effect is a cognitive bias that manifests itself as a tendency to overestimate the probability of one's success at a task perceived as hard, and to underestimate the likelihood of one's success at a task perceived as easy. The hard-easy effect takes place, for example, when individuals exhibit a degree of underconfidence in answering relatively easy questions and a degree of overconfidence in answering relatively difficult questions. "Hard tasks tend to produce overconfidence but worse-than-average perceptions," reported Katherine A. Burson, Richard P. Larrick, and Jack B. Soll in a 2005 study, "whereas easy tasks tend to produce underconfidence and better-than-average effects."
The hard-easy effect falls under the umbrella of "social comparison theory", which was originally formulated by Leon Festinger in 1954. Festinger argued that individuals are driven to evaluate their own opinions and abilities accurately, and social comparison theory explains how individuals carry out those evaluations by comparing themselves to others.

Dolf Zillmann (born March 12, 1935) is dean emeritus, and professor of information sciences, communication and psychology at the University of Alabama (UA). Zillmann predominantly conducted research in media psychology, a branch of psychology focused on the effects of media consumption on human affect, developing and expanding a range of theories within media psychology and communication. His work centred on the relation between aggression, emotion, and arousal through media consumption, predominantly in pornography and violent genres of movie and television. His research also includes the effects of music consumption, video games, and sports.
Zillmann's influence within both the fields of media psychology and communication was highlighted by Ellen Baker Derwin and Janet De Merode finding Zillmann to be the seventh most contributing media psychology author between 1999 and 2010. (Full article...)
