Psychology: the science of mental life, both of its phenomena and their conditions. (James1, 89) The study of mental and behavioral processes. (Kleinman, 7) The science of human nature. The study of sensitivity, action, and consciousness. (Pyle, 4)
Examines mental processes … manifested in our thoughts, speech, and behavior. From the Greek words psych, meaning ‘soul’ or ‘mind,’ and logia, a ‘study’ or ‘account.’ Psychologists themselves are unlikely to agree on a single definition of the word. (Collin, 10) The definition offered by any particular psychologist reflects their own interpretative “bias,” therefore some would lay more stress on the ‘mind’ part of this definition, others the ‘behavior’ part. Some psychologists might even offer the view that the study of human behavior cannot, and indeed should not, be considered a scientific discipline. (Cardwell, 195)
