What are these psychologies about?

Hi,

Cognitive psychology is the school of psychology that examines internal mental processes such as problem solving, memory, and language. Cognitive psychologists are interested in how people understand, diagnose, and solve problems, concerning themselves with the mental processes which mediate between stimulus and response.

Forensic psychology is the intersection between Psychology and the Criminal justice system. It involves understanding criminal law in the relevant jurisdictions in order to be able to make legal evaluations and interact appropriately with judges, attorneys and other legal professionals. A forensic psychologist can be trained in clinical, social, organizational or any other branch of psychology. In the United States, the salient issue is the designation by the court as an expert witness by training, experience or both by the judge.

Social psychology is the study of how social conditions affect human beings. Scholars in this field are generally either psychologists or sociologists, though all social psychologists employ both the individual and the group as their units of analysis.

Hope this helps!
