COGNITION
AND THINKING
Cognition
is the
·
The
process of knowing, as well as
what is known.
·
Cognition
refers to the higher mental
processes.
·
It
is through these mental
processes that humans
understand the world,
process information,
make
judgments and decisions, and
communicate knowledge to
others.
·
Memory,
intelligence, and language
are important aspects of
cognition.
The
term cognition
is
used in several different
loosely related ways. In
psychology it is used to refer to
the
mental
processes of an
individual, with particular relation to a
view that argues that the
mind has internal
mental
states (such as beliefs,
desires and intentions) and
can be understood in terms of information
processing,
especially when a lot of abstraction or
concretization is involved, or processes
such as
involving
knowledge, expertise or learning for
example are at work. It is
also used in a wider sense
to mean
the
act of knowing or knowledge, and
may be interpreted in a social or
cultural sense to describe the
emergent
development of knowledge and concepts
within a group that
culminate in both thought
and
action.
Cognitive
Psychology
The
branch of psychology that
studies cognition, and
related areas and
issues.
Cognition
is commonly known as
Thinking
What
Is Thinking???
·
The
information that our mental
faculties receive or generate is in
the form of
mental
representations.
·
These
mental representations may be in
various forms e.g. in terms
of words, visual images,
or
may
be sounds.
·
Woodworth
said that thinking is mental
exploration and according to
Ruch, thinking is a behavior in
which
at
least some of the subjects
that are dealt with
are not physically present
to sense but are represented
by
symbols,
or in other words, thinking is
actually a series of symbolic activities
which represent previous
learning
experiences and an individual's
thought processes.
·
Most
of the time, human beings are
thinking. Even when they stop
thinking or reading or writing,
ones
thought
wonders on something else
and this can be past,
present or future or pleasant or un
pleasant, or it
may
be even day- dreaming; they
all are the part of thinking
phenomena.
Thinking
Thinking
is the process whereby these
mental representations are
manipulated. The process
of
thinking
transforms these representations
into a new and different
form. The transformation
may
be
made:
·
For
finding answers to
questions
·
For
finding solutions to
problems
·
For
finding facts and exploring
reality

Try
to see what different types
of mental images we
experience!!!!!
Close
your eyes for a moment and
try to:
·
See
the face of your
mother?
·
Hear
the voice of your favorite
singer?
·
Feel
how your favorite food
tastes?
·
Feel
how your favorite perfume
smells?
·
Imagine
how the prick of an
injection feels?
Probably
You Will Be Able To Do All
of These Things
The
stimulus is not there but we
can feel it...
mentally
How
do all these mental
processes take
place???
·
Thinking
is a subtle, and continuous
process.
·
Our
brain is the most intricate,
complex, sophisticated, and
yet `quite' machine in the
universe.
Fundamental
Elements of Thinking
·
Mental
Images
·
Concepts
1.
Mental Images
·
Mental
images are an integral part
of the thinking process; in
fact a major part of our
thinking
consists
of these images.
·
These
are mental representations of
the objects and events
that we are, or we have
been, in
contact
with.
·
These
images are not necessarily
visual in nature; images can
be related to all sorts of
sensory
experiences.
·
Psychologists
have developed exercises for
enhancing people's ability to
work on their mental
images,
in order to sharpen their
thinking capacity and
thinking skills e.g. problem
solving
skills,
brain teasing, creative
thinking exercises.
·
There
is no dearth of research available
suggesting that mental
images, when used as
mental
rehearsals
can be very helpful in
improving other skills,
besides thinking, as well
e.g. jogging,
athletics,
dancing, and public
speaking.
·
Images
are also used as important
tools in Interventions
designed for handling
psychological
problems
e.g. Relaxation exercises, or
meditation.
2.
Concepts
·
Objects,
events, or people sharing
common characteristics and
properties are categorized
and
classified
as one.
·
This
categorization is known as "concepts'.
·
Different
categories are different
concepts e.g. the concept of
different objects, people,
or
events.
168
Introduction

If
someone asks you, "Who
are your class fellows?" How
will you respond?
You
might say:
·
"One
short girl, one medium
height boy, a tall girl
and a tall boy, one
girl with long hair,
and
one
boy who is bald".
·
OR
·
"Three
boys and three
girls"
This
is a type of categorization based
upon the concept of
gender.
The
same applies to other
objects and event e.g.
furniture, fruit, clothes
etc.
Use
of "Concepts" In Thinking
World
·
Concepts
are the categorization of objects,
events, or people that share
common properties
·
When
someone asks you, what is the main
thing required for your
room? One may start talking
in terms of
items
like, bed, chairs, curtain,
carpets etc, or `furniture
and fixtures' as a single
category.
·
These
small categories reflect the operation of
concepts and the process of
cognition
·
Concepts
make possible the establishment of
cognitive categories, and
enable us to organize complex
phenomena
into a simpler and
conveniently manageable
form.
Imagine
how many things we are in
contact with in the world around
us. Do we, or can we name
all of
them
all the time??????
·
Newly
encountered objects easily
fit into our cognitive
structure, if the conceptual category is
already there.
Therefore,
·
If
you know what a doctor does,
then you can recognize
any type of doctor, in any
part of the world, in
any
type
of attire, in any type of treatment
setting.
·
Imagine
if we did not have concepts
of fruit, vegetables, grains,
furniture, or weather!!!!
·
Concepts
help to define, explain and elaborate
complex phenomena into simple,
understandable and
usable
categories,
and they also include data
from past
experiences.
·
There
are three main types of
concepts;
a)
Artificial concepts
b)
Natural concepts
c)
Prototype concepts
a)
Artificial Concepts
·Concepts
that have a unique set of traits
and features.
·These
concepts are easy to define
and elaborate. e.g. a
rectangle has two opposite
sides equal, if it is not
the
case,
then it is not a
rectangle.
·But
our every day concepts
are much more difficult than
these concepts. e.g. what is the
definition of an
animal?
b)
Natural
Concepts
Known,
familiar and relatively simple
concepts that have rather
loose features to define and
explain them.
·
These
concepts are not universal
in nature___ such as rectangle has
two opposite sides equal, if it is
not,
and
then it is not a rectangle. This is
not the case in natural
concepts.
People
e.g. defining an animal can
vary ·They in their definition
and explanation?Simple
and complex
concepts
·
Some
concepts are simple in the
sense that they are clearly
defined.
·
When a
concept is clearly defined, it is easy to
distinguish an example from a non-example
e.g the concept
of
a square, or an equilateral
triangle.
·
But
some concepts are rather
difficult to define. These are
defined in a variety of ways, and
marked by a set
of
complex features.
·
These
may be ambiguous, overlapping, and
even abstract e.g. a bird,
or a chair.
169
Introduction

VU
·
Most
of the things that we are in contact
with in our everyday life
are not as easy to define as
a square or a
triangle
e.g. defining `obsessive-
compulsive disorder'.
·
These
may also involve the
subjective experience of the
person.
And
what about the concept of a
comfortable chair or an easy or a
difficult task??????In
such
situations
we need specific, and rather
exact examples of a concept
i.e., prototypes.
c)
Prototypes
·
Examples
of a concept that is typical
and highly representative of a
concept.
·
Prototypes
are used to define and
explain objects and ideas
that cannot be defined in a
clear-cut
and
straightforward manner.
·
E.g.
the prototype of a table can
be the `dining table', or
the prototype of a bird can
be a `crow'.
Agreement
on prototypes
·
Usually
people in a society, or those
belonging to a particular discipline,
are unanimous about
the
prototypes
of a concept e.g. if we have to
give a prototype of a vehicle,
then we will talk about
a
`car'
and not and escalator' or
`elevator', although these
also move and take us
from one place to
another.
·
On
the other hand, if we are
talking about varieties of
`stairs', then we can
probably take escalators
as
an example.
·
What
will happen if psychologists do
not have a common definition
of mental illness?
·
How do
concepts help in
thinking?
·
We
live in a complex world of objects,
ideas, and relationships. It is
with the help of concepts
that we
understand
this world.
·
Concepts
make it possible to communicate
ideas, thoughts, and feelings
even when the object of interest
is
not
actually present.
Thinking
and Reasoning
·
Only
humans can think in ways,
which no other organism is
able to, as they have
the ability to
contemplate,
analyze, recollect, and plan
out, and carryout those
behaviors.
·
Humans
are the only ones
who are capable of using
foresight
as
well as hindsight
·
Even
when we are not thinking,
our mind wanders on present,
past, future, pleasant or un
pleasant, favorite
or
not so favorite
things.
And
even we are dreaming or day-
dreaming; actually it is also a form of
thinking.
Reasoning
·
It
is the ability to use reason,
logic, past experience, and
learnt information for
mental processing.
·
For
decision-making, and problem
solving etc.
Deductive
Reasoning
·
Deductive
reasoning is the process
whereby logical conclusions,
inferences, and implications
are
drawn
by using a set of assumptions.
These inferences are then
generalized over, or applied
to,
specific
cases.
·
The
assumptions or premises that
are used for drawing
conclusions are thought to be
true and
base
upon reality. In many cases
they are considered to be
unchallengeable.
But
at times these premises may
turn out to be false when
tested in reality e.g. all
men are brave, or men
do
not
cry.
·
Evaluating
syllogisms is a techniques used
for studying deductive thinking.
·
A
syllogism contains a series of
two assumptions or premises
that are used for drawing
conclusions e.g.
·
All
women are talkative.
·
Anna
is a woman.
·
Therefore,
Anna is talkative.
170
Introduction
to Psychology PSY101
VU
·
This
type of deductive thinking is largely influenced by
cultural backgrounds of people.
·
It
has been seen that people
from more developed societies
use rather.
·
Abstract
and logical thinking, which they
acquired through their
experience, and learning.
·
People
from less developed cultures mostly rely
on concrete
modes of reasoning.
·This
sort of difference is largely due to
the type of high quality,
sophisticated education, variety
of
learning experiences, and the pressure to
think logically and
independent.
