Cognitive psychology is the study of the mental processes that contribute to behavior, including the internal behaviors of thinking and feeling (Kellogg, 1995, p. 4-5). Much of what the mind does can be compared to a computer processing sensory information and responding by moving the muscles of the body; however, the mind also performs other important functions such as assigning meaning to events and objects and reacting emotionally to external and internal stimuli. An important assumption in cognitive psychology is that the mind is a product of biological processes that have emerged during evolutionary history. Given this grounding in empirical science, it should come as no surprise that cognitive psychologists are interested and engaged in the discoveries being made using modern brain imaging technologies (Parsons, 2001). To better understand the roots of cognitive psychology this essay will review several key milestones in the history of this discipline and discuss the importance of behavioral observation.
Key Milestones
Although the field of psychology has always contained elements that would later be claimed by cognitive psychologists, the first historical milestone was the creation of structural psychology by Edward Bradford Titchener in America in 1892 (Kellogg, 1995, p. 8-9). This model proposed that consciousness was the product of different processes, including sensation and feelings. The main assumption is that mental structures or elements...
Although self-observation (introspection) was developed by Tichener and Wilheim Wundt in Wundt's laboratory, this method proved to be too unreliable to fit within the scientific method.
Influenced by Darwin, William James published Principles of Psychology in 1890 and introduced Functionalism to a limited audience (Kellogg, 1995, p. 9-10). In contrast to structuralism and its mental elements, functionalism focuses on the mind's purpose and the mental operations that serve that purpose. James world view was that of an evolutionary biologist; therefore, functionalism assumed that evolutionary selection had determined the processing capabilities of contemporary brains. In other words, functionalism assumes that the mind adapts to the demands of the environment to increase the chances of a species survival. James Angell, then president of the American Psychological Association, brought wider attention to functionalism during an address to members in 1906. Accordingly, functionalism dominated American thinking during this period.
In 1913, James B. Watson ushered in the era of behaviorism in America (Kellogg, 1995, p. 11-12). The goal of behaviorism was to limit psychological research to objective measures of behavior; therefore, the concepts of consciousness and introspection were thrown into the waste bin. For example, Watson respected Ivan…

Psychology is an important field of study mainly because it can be used to enhance the lives of people as it increases an individual's level of self-understanding, well-being, and quality of relationships. The main reason for the impact of psychology on people's lives is because this field focuses on describing, explaining, predicting, and controlling the mental and behavioral processes of an individual. As a broad field of study, the field
Cognitive Development Jean Piage is a luminary as far as cognitive development theory goes. This is because of his contributions in his intellectual development theory. According to Piaget, intellectual development is a continuation of innate biological processes. He emphasizes that children go through four sequential processes of development. These four stages also occur with sub stages within them. The sensory motor stage: 0 to 2 years; intuitive stage: 2 to 7 years;
Psychology Development Early Childhood Medelein N. Moody, (2013). A Relational Aggression Intervention in Early Childhood. University of Nebraska. ProQuest LLC. The paper was aimed at interrogating the relational aggression in early childhood and if there are interventions within the school setting that can act to reduce the aggression. This intervention is referred to as the Early Childhood Friendship Project and entailed taking stock of the changes in the behavior of the children as
In addition to the above noted areas, there is also green politics, deep ecology, the feminist and gay rights movements, and the psycho-spiritual wing of the peace movement. This takes into account an integrated and balanced view of human nature and maintaining harmony in the grand scheme of existence. As noted by Maureen O'Hara, past president of the Association for Humanistic Psychologists: "As the world's people demand freedom and
Clinical Psychology / Bulimia Nervosa The beginnings of clinical psychology date back to the year 1492, and it has changed from the mere treatment of mental illness to an entire field of research and experimentation, which has helped those individuals who have been affected by any form of mental disorders, like for example, the eating disorders like bulimia nervosa and anorexia nervosa prevalent among adolescent and twenty-year-old women all over the
Knowing this, Strenger points out that therapists need to consider "who can work with whom," because the therapeutic outcome may be greatly affected by the "chemistry" between therapist and client. The egalitarian principle in the therapeutic relationship gets played out further in qualitative studies (such as Gallegos, 2005 and Cohen, 2005) in which client experiences in the mental health system and subjective accounts of symptom relief from psychotherapy are
