INTRODUCTION TO COGNITIVE PSYCHOLOGY
Cognitive psychology covers several important philosophical concepts that
relate to the human mind and behavior. The nature versus nurture debate
considers whether human behavior is primarily influenced by innate
biological factors or by environmental experiences. The free will versus
determinism debate considers whether humans have agency over their
choices and actions or if these are predetermined by other forces. Dualism
versus monism deals with the relationship between the mind and body -
whether mental states are distinct from physical states or if the mind is
just part of the physical brain. These philosophical issues provide an
important backdrop for cognitive psychology's examination of mental
processes like perception, attention, memory, language, thinking and
consciousness.
What is Cognitive Psychology?
Cognitive psychology is the study of mental processes involved in
thinking, knowing, remembering, perceiving and communicating. Right
now as you read this, your mind is actively engaging in many complex
cognitive tasks. You are using visual perception to interpret shapes as
letters and words. You are accessing your knowledge of vocabulary and
grammar to comprehend the meaning. You are using memory to connect
ideas across sentences and paragraphs. Cognitive psychologists are
interested in understanding the underlying mental processes that allow us
to carry out everyday cognitive feats like reading, as well as how these
processes develop and sometimes break down.
Cognitive psychology examines a wide range of mental phenomena that
make up cognition. This includes attention, perception, learning, memory,
language, problem solving, creativity and decision making. Cognitive
psychology looks at questions like: How do we recognize objects and
faces? Why do we remember some things but not others? How do we
understand and produce language? The goal is to understand the
underlying mental processes that allow cognition to take place.
Cognitive psychology involves two related meanings:
1. The study of various mental activities like attention, perception,
learning, memory, language, thinking, reasoning and decision
making.
2. A particular theoretical approach to studying psychology that
focuses on mental processes and information processing as
explanations for behavior.
For example, a cognitive psychologist might study questions like:
Why do distant objects appear smaller in foggy conditions?
Why do many people vividly remember certain experiences from
childhood but not recent events?
Why do some people fear air travel more than car travel despite air
travel being statistically safer?
Why is it easier to remember people you met in childhood versus a
week ago?
Why Study the History of Cognitive Psychology?
Looking at the history of cognitive psychology is useful for several
reasons:
1. While cognitive psychology has evolved over time, many of the
fundamental questions have remained constant. Tracing this
progression gives insight into how humans have long been
fascinated by thinking about thinking.
2. Ideas in cognitive psychology often develop through a dialectical
process - a pattern where ideas evolve over time through debate
and integration of different viewpoints. Typically, a thesis is
proposed, then countered by an antithesis, leading to a synthesis of
the most credible aspects of each viewpoint.
3. This dialectic helps show that contrasting perspectives are not
always mutually exclusive. Sometimes what may appear to be
opposing views are actually complementary when properly
understood and integrated.
4. The dialectical approach is more common in Eastern cultures while
Western thinking tends to be more linear. Eastern thought
emphasizes context, relationships and contradictions while Western
thought focuses on objects and linear progressions. Both offer useful
insights for cognitive psychology.
5. Understanding this history of debate and integration of ideas
provides a foundation for current theories and practices in cognitive
psychology.
Why Study Cognitive Psychology?
There are several key reasons why the study of cognitive processes is
important:
1. Cognition forms a major part of human psychology. Perceiving,
thinking, reasoning, remembering and using language are integral
to nearly everything we do. Understanding cognition provides
insight into the fundamentals of human psychology.
2. The cognitive approach has been highly influential across subfields
of psychology like clinical, educational, social and developmental
psychology. Core cognitive concepts like information processing,
memory and perception provide a framework for understanding
many psychological phenomena.
3. Cognition is central to our everyday lives. Gaining a better
understanding of how our minds work through the study of cognitive
processes allows us to use this intricate equipment more effectively
throughout our daily activities. From reading, to learning, to
communicating, cognition enables us to function and survive.
Free Will Versus Determinism
A longstanding debate in philosophy and psychology considers whether
human behavior is the result of free will or deterministic factors.
The notion of free will holds that people have agency and autonomy
over their choices and actions. Our consciousness gives us an
internal space to contemplate decisions which leads to a sense of
free choice. Free will is fundamental to concepts like morality and
personal responsibility.
In contrast, determinism claims human behavior is driven by causal
factors outside individual control, both internal and external. Our
thoughts can be reduced to physiological neuronal processes that
could theoretically be predicted like chemical reactions.
This issue remains significant today. If free will is an illusion and human
behavior is predetermined, what are the implications for holding people
morally accountable for their actions?
Free will: the idea that people consciously make autonomous
choices that guide their behavior.
Determinism: the idea that behavior is dictated by causal factors
beyond an individual's control.
Modern cognitive psychology tends to favor a view of behavior arising
from unconscious cognitive and neural processes rather than conscious
free will. However, the nuances of moral responsibility and individual
differences still require consideration.
Mind-Body Debate
Cognitive psychology intersects with the philosophical mind-body problem
- questions over the fundamental nature of mental states in relation to
physical brain states.
Materialist theories hold that mental states arise solely from
complex computational processes in the physical brain.
Dualist theories contend that mental phenomena are non-physical
and distinct from the physical brain.
This issue connects with other philosophical challenges:
1. The semantic question of how words for internal mental states like
"pain" or "joy" get their meaning. Can individuals truly understand
the subjective experience of someone else's mind?
2. The epistemological question of how we gain knowledge about the
contents of other minds. For example, do animals or artificial
intelligences have genuine mental states?
Modern cognitive psychology tends to favor a materialist view with mental
processes emerging from the computational interactions of physical
neuronal networks in the brain. However, active debate continues over
the ultimate relationship between subjective experience and underlying
brain states.
