Cognitive psychology: key concepts and applications

Evolution of Cognitive Psychology as a Discipline

The advancement of cognitive psychology since the era of Thomas Aquinas, who was the foremost person to divide behavior into two distinct areas; cognitive and affective has tremendously evolved. The lodging of research on the field provides practitioners a clear view of the subject matter. Cognitive psychology has been existent for centuries in diverse forms based on its defining culture (Eysenck & Keane, 2005). As science progressively gets sophisticated, numerous theories and beliefs have fallen aside in favor of more legitimate evidence towards contemporary developments in the discipline. Cognitive psychology is the study of mental processes. During the nineteenth century, cognitive psychology became an emergent theme of concern in the discipline of psychology. This epoch saw numerous psychologists and scholars concentrate on the study of human behavior as it emanates from internal states such as moods, thoughts and feelings (Goldstein, 2008).

Cognition

Cognition is the method of obtaining, keeping, using and applying knowledge and intelligence. It is typically the science of knowing. Cognition means all the processes through which the sensory input goes under transformation, reduction, elaboration, storage, recovery, and eventual application. Cognition is inclusive of the processing of information (Eysenck & Keane, 2005). It slightly excludes emotions processing. Cognition inculcates all mental processes. For instance, gaining knowledge, comprehending, recalling, assuming, analytical problem solving, and perceiving are all components of cognition.

Cognitive psychologists examine behavior as an avenue to decipher the underlying mental activities, same to how physicists decipher the existent gravitational force referencing from object behaviors on earth. Studying mental activities covers a large ground. They include an understanding of languages, problem solving, remembrance, attention and making decisions as expounded.

Since time immemorial, cognitive psychologists have applied the above concept applying scientific methods as their fundamental tool. These researchers assume that the mind is a machine type from where they elucidate how the machine works internally. Thinking is a process that all people undertake daily. This makes cognitive psychology a pertinent discipline (Goldstein, 2008).

Such a comprehensive definition shows that cognition encompasses everything all human beings would do; all psychological experiences are cognitive experiences. Though cognitive psychology relates to all human activities rather than segments, the apprehension is that it originates from a specific point-of-view yet other viewpoints are overtly necessary and justifiable.

The Interdisciplinary Perspective & Emergence of Cognitive Psychology

Being an essential part of psychology as a whole, cognitive psychology is also a component of the general interdisciplinary discipline of cognitive science. Cognitive science is the cross-disciplinary examination of intellect and psyche. It appreciates various fields such as neuroscience, anthropology, linguistics, philosophy and psychology (Eysenck & Keane, 2005). These other fields have had a consummate influence on cognitive psychology as it has influenced them.

These disciplines apply cognition based on psychology. Cognitive psychology is the interdisciplinary field that scholars apply to understand the mind. Researchers derive their conclusions from experiments. All the related fields share the same factors such as memory, attention, thinking and linguistics. This makes cognitive psychology an interdisciplinary discipline.

Behaviorism was the top approach within psychology, however it may not explicate on the acquisition and application of language. Noam Chomsky revolutionized the discipline of linguistics with his notions and was extremely influential in querying simple and one-dimensional behaviorist clarifications on the behavior of language (Goldstein, 2008). Philosophical matters such as the consciousness and nature of the mind have taxed renowned thinkers for centuries. Such issues are indispensable in cognitive psychology.

The Emergence of Cognitive Psychology as a Discipline

A Proper understanding of the appearance of cognitive psychology as the mandated approach in psychology comes when a person critically studies the history of psychology. Contemporary psychology is apparently young. As in most sciences, it has not firmly developed into one path but divided into many subdivisions. The field has evidenced remarkable shifts in what are significant disciplines and which is the best and precise method and procedure to study behaviors of people.

These remarkable changes are paradigm shifts where "paradigm" means a unified and acceptable method of study. A tally of occasions and events resulted into the emanation of cognitive psychology. Broadbent and a panel of psychologists were to advise engineers within the military on ways of creating a panel that would accrue flying and performance with the buttons and numbers on their dashboards (Goldstein, 2008).

This caused the psychologists to dig deeper into the behaviors and to apply the new improvement. During that time, a series of studies and discoveries in cognitive psychology were on the upsurge. Miller discovered a law that governed short-term memory. His research on the human aptitude on short memory is the major reason phone numbers have seven digits. George discovered that the majority of people could recall between five and nine items when they faced them once. Miller's invention was pertinent in the appearance of cognitive psychology since it depicted that there existed a law for short-term memory information level and mental processes inclusive (Goldstein, 2008).

Decline of Behaviorism

In the initial half of the twentieth century, behaviorism ruled the psychological discipline. In the middle 1950, cognitive behavior emerged again after researchers and psychologists from several fields started to develop theories regarding the human mind and how complex it is. Behaviorism declined even further and cognitive psychology became dominant (Eysenck & Keane, 2005). In spite of finding a firm correlation between the general number of lesions made to the brain and the extent of errors made in the maze, he failed in finding a specific region of locality of the maze memory. His conclusion affirmed that the memory of the maze is scattered all over the brain. Lashley's work posed as a departure from the behaviorist's disinterest to consider internal processes such as memory processes.
