In the beginning, psychology was defined as the study of the mind.
With behaviorism, psychology was known as the study of behavior. Cognitive
psychology once again brought the definition around as the study of the mind.
Cognitive psychology focused on several different disciplines. Among these
disciplines were psychology, linguistics, computer science, philosophy,
anthropology, and neuroscience (Watrin & Darwich, 2012). Each discipline
offered a different perspective on the subject of cognition. While behaviorism
and cognitive psychology both aimed to explain mental processes, there were
some differences that set the two apart.
Defining Cognitive Psychology
Cognitive psychology is the field of psychology that emphasizes
the study of mental processes (McGraw Hill, 2010). These processes include
thinking, language, problem solving, knowing, reasoning, judging and decision
making. Cognitive psychology concluded that humans were not pushed or pulled by
environmental factors. Instead, humans sought out experiences, altered and
shaped experiences and used mental processes to transform information (Wood,
Wood, & Boyd, 2011). Cognitive
psychology also studied how people view and understand the world. Subjects
wanted to describe the patterns and irregularities during the operation of his
or her mind. There were several key milestones in the development of cognitive
psychology.
Key Milestones in the Development of
Cognitive Psychology
Criticisms
of Behaviorism
In the 1950’s, there were problems brought forth in relation to
behaviorism. Behaviorists focused more on observable behaviors and not on the
importance of genetics. Behaviorism’s main emphasis was that behavior was primarily
determined by environment (Wood, Wood,
& Boyd, 2011). Cognitive psychologists studied fixed – action
patterns whereas behaviorists had no answers about them. Fixed – action
patterns are complex behaviors engaged in with little to no practice or reward
(Willingham, 2007). According to behaviorism, such behaviors should require
more practice or reward. Chomsky raised the issue of language (Willingham,
2007). He stated that the behaviorists could not account for language. It was
his belief that language was generative (Willingham, 2007). Behaviorism
explained repeating a behavior after practice or reward. However, behaviorism
could not explain displaying behaviors without practice or reward. The main
criticism of behaviorism was that it could not explain language or strategies.
Information
Processing
In the 19th century the brain was compared to a
telephone switchboard. Cognitive psychologists compared it to a computer. Thus,
it was believed that humans used representations and processes similar to
computers. In using this metaphor, the term information was processing was
created when explaining the mind. Information processing is the way people take
in, use and store information (McGraw Hill, 2010). Cognitive psychologists
concluded that humans take in information (through sight and hearing),
transform information (by interpreting it in memory) and then put out
information (by speech). When using the computer metaphor, behaviorists only
study the screen, which is observable. Cognitive psychologists study the
software, which describes the brain (Willingham, 2007).
Artificial
Intelligence
Artificial Intelligence can be defined as “the pursuit of
intelligent behavior by a computer” (Willingham, 2007, p 29). It can also be
defined as “the programming of computer systems to simulate human thinking in
making judgments and decisions” (Wood, Wood,
& Boyd, 2011, p 229). There are different types of artificial
intelligence programs. One type is the Artificial Neural Network (ANNs). This
program mimics human brain functioning. A second type carries out highly
specific functions within a limited domain. Research has shown that it would be
impossible for a computer to completely replace a human. In fact, many
cognitive tasks that humans find easy are difficult to teach a computer (Wood,
Wood, & Boyd, 2011). Many aspects of
language processing are difficult for a computer to handle.
Neuroscience
There have always been links between brain structure and function.
Neuroscience examines how the brain and the nervous system determine behavior
(McGraw Hill, 2010). It also studies how a person’s body influences his or her
behavior. The neuroscience research that is conducted helps us understand
sensory experiences, states of consciousness, motivation and emotion,
development through the life span, and physical and psychological health. The
research in neuroscience has also led to the creation of medications and
treatments for psychological health as well as physiological health (McGraw
Hill, 2010).
Importance of Behavioral Observation in
Cognitive Psychology
Behavioral observation is important in cognitive psychology just
as it is in behaviorism. Behavioral observation helps researchers test
cognitive theories. Whereas behaviorists only studied observable behavior,
cognitive psychologists studied mental processes. When studying these processes,
researchers explained “how the unobservable processes interacted with the
observable world” (Willingham, 2007). Instead of just creating theories of
behavior, researchers now named the expected behavior if the cognitive theory
was right. There are several types of research that can be used to test
theories. These are descriptive, relational, and experimental research. Descriptive
research does not provide clear data in cognitive psychology but it is a
springboard for other works. Descriptive research is a person’s description of
a behavior. This type of research can be collected by naturalistic observation,
case studies or self – report. Relational research is closer to what cognitive
psychologists need rather than descriptive research (Willingham, 2007). In
relational research, two or more aspects of the world are examined and any
relationship is determined. This type of research is about associations in
behavior. In experimental research, one factor is altered while the effect of
the alteration on the other factor is studied. These types of research are
important in behavioral observation and helping cognitive psychologists test
his or her theories in cognition.
Conclusion
At first, behaviorism was the primary
perspective in psychology. In the 1950’s cognitive psychology was introduced
and it gained momentum in the 1960’s (Willingham, 2007). The differences in
between behaviorism and cognitive psychology became a central debate in the
psychological field. Behaviorism focused on the study of observable behavior,
however cognitive psychology had answers to questions that behaviorism did not.
By studying mental processes such as thinking, language, and reasoning
cognitive psychologists expanded the field of psychology to include more than
what could be observed (McGraw Hill, 2010).
