So hello and welcome to this introductory course in cognitive psychology which is titled basic cognitive processes. I am Dr. Manju Antil. I am an assistant professor of psychology. Today’s lecture is titled Introduction to cognitive psychology. We will talk about what cognitive psychology is actually about.
But before we get
deeply involved in the topics of cognitive psychology and what these basic
cognitive processes are let us ask more basic questions. The basic question
is what is psychology? Now should take this question around and take this
question to your colleagues, your family members and the people around you.
You will actually get a variety of responses. For example, some of them could tell you that psychology is about knowing and predicting people's behaviours. In this comic strip, you might see that both the rat and the lab experimenters have a sense of controlling each other’s behaviour. They seem to know that they are doing something that will actually predict the next person's behaviour.
That is one way,
another response that a lot of students in psychology get and a lot of students
get actually, you know really embraced by this is that a lot people would come
and tell you that psychology is about reading people’s mind. But at some point, the other people would actually go out and say, ‘Yes, I am a student of
psychology, but that does not mean that I can read your mind’.
Psychology is not
really about reading people’s minds though it might help you in other ways. One
of the last answers about what psychology you could get is that psychology
could shape people’s behaviour in social situations. You might see this example
here which says in there is a plank advertisement that says that you please through your
letter on the ground or on the grass, but it actually gets the exact opposite
effect okay.
This is also one of the examples which psychology or one of the applications that psychology has. Moving ahead, but if psychology is just about behaviour modification I would say no. It actually offers you much more, we will see what.
What is the subject
matter psychology then? Let us begin with the basic definition.
Psychology as a
science, is a science which studies mental processes, experiences and behaviours
in different contexts. We will visit each of these one by one. What are the
mental processes we are talking about whether we are talking about just brain
activity or mental activity or mental functions. That part is not really clear,
but we can take some examples such as learning, remembering, perceiving feeling
those kinds of things.
Those are also examples of what psychology helps you do or what psychology is actually studying.
What are experiences?. Experiences are subjective feelings, what are you feeling at
any point in time what is your awareness, let us say for example, I am in this
particular room, I see people around me or I see this screen or I am seeing and
talking to you guys.
Also, psychology could
actually help you understand experiences whether somebody is experiencing a
normal state or an altered state may be under the influence of a particular
drug or something. Or say, for example, very simply put somebodies other
energetic or active or some others may be feeling other passive or sad.
All of these come
under the view of psychology. Coming to behaviours, what are behaviours?
Behaviours most simply put our responses or reactions to the events and actions
in the world. You know we are surrounded by agents, we are surrounded by people
and situations and how we actually come out acting is basically what is a
behaviour.
It is another
definition which I am taking here. Also, behaviour includes sometimes spontaneous activity to achieve various goals or motives. You might
have a goal of becoming somebody, or you might have a goal of becoming a
cricketer, you will continue and you will have some behaviour which will lead to you becoming a cricketer.
All of that also forms part of what is called behaviour. Behaviours conclude in two ways. One of the ways is either simple or complex behaviour,
what is the simple behaviour. Simple
behaviour is say for example the most typical stimulus and reactions. Say, for
example, if I ask you to touch the tip of a needle, you will probably try to
touch it, but you will take your hand back very quickly.
It is in response to
you being pricked. On the other hand, I could actually give you more complex
behaviour that being I could ask you to go in and make a cup of coffee for me. That
is basically a complex behaviour which will actually involve a chain of very
simple behaviours. Another way in which you can actually look at behaviour is
whether behaviour is covert or cowardly.
Coward behaviour is
simply the behaviour that can be observed by others the actions let you do
the things which you say or say, for example, the stage that you experience and
which you show people. That is cowardly behaviour. Covert behaviour on the other
hand is something that is typically going on in your mind think that you would
experience feelings of attraction, feelings of anger, discusting all of that
or for example, simply processing the world around you.
All of that processing
is happening inside your head which is an example of covert behaviour. Moving
ahead, this is another commonly asked question of whether psychology is a science or is just about common sense. We get asked this question a lot of times. Now if
psychology were to be common sense, it would be found with a few problems.
Say, for example,
confirmation bias. Now one of how you can describe a confirmation
bias is that it is your internal yes man. If you say for example, develop a
particular opinion or a theory about something in the world some person whom
you know, you will actually look for and collect evidence that agrees with your
perspective or that agrees with your point of view.
That basically is a
confirmation bias okay. Another problem with common sense is basically stereotypes. Say, for example, people have particular opinions and actually look at
the world through those opinions. Say, for example, the most common stereotype that
you might have heard or come across of few times is the aspect of, the fact that females are bad drivers.
These are all the most
common stereotypes that you will hear. So for example, if somebody comes and
tells you that there has been an accident near your house and there was a woman
involved automatically some of you will make the conclusion that the woman must
be at fault in this accident. However, close examination and scientific
observation might tell you that this might not be the case.
So psychology in that
sense is slightly different from common sense. I would say much different from
common sense actually. Moving ahead, let us talk about how psychology is
actually structured as a discipline. As a discipline basically, psychology seeks
to understand and explain how the mind works and how the different mental
processes lead to different behaviours.
Psychology traces also
in that sense to minimise bias and the explanation of behaviour and experience
in a variety of ways. You say that psychology is different from common
sense. However, psychology also recognises the importance of
subjectivity in some cases, though always trying to develop a scientific
understanding of those phenomena.
So psychology basically
draws from two screens of knowledge. One makes use of methods in physical
and biological sciences and the other uses methods of social and cultural
sciences while studying a variety of psychosocial phenomena. In the first
case, psychology focuses largely and biological principles to explain human
behaviour thinks as how the brain functions, what the response to
various neurotransmitters in the brain, and stuff like that.
On the other hand,
psychology focuses on how behavioural phenomenon can be explained in terms of
the interaction that takes place between the person and the social context, how the person behaves when he is alone, or compare to how the person
behaves when he is confronted with the group of people when he is part of a
larger group.
That is kind of
phenomenal. As a science psychology applies what is called the scientific
method? It emphasizes objectivity it emphasizes that your opinion should be
based on facts, and your opinion should be based on measurements basically
which is called empiricism. In it, psychology uses of particular method or
it basically functions around a particular model which has been called the
hypothetic deductive model.
So let us have a look at this model for a
while, this is what this model looks like. It basically begins with some
kind of literature review, you actually look into literature, you actually see
what the questions people will ask you, and actually look to see what the
papers people publish. What are the topics that people have been interested
in studying and to what extent they have actually studied them? What are the
questions relevant to those topics and how do people approach those
questions.
Then basically move on to formulating your own
research questions based on whatever literature you actually started.
You move on to design in an empirical study it could be an observation study or
it could be a basic experiment we will talk about these things later as we go on
into the course. And then once you conduct an experiment you get some
data, you get some measurements.
You analyse those data,
you analyse that data and basically that helps you reach particular
conclusions. Once you reach a particular conclusion you also have to say
something about that particular topic. This then gets added to this body of
research literature which people coming up to you might again, review to
contact their own research questions.
That is what psychology
broadly uses as a method when we move on we actually talk about this kind of
method in more detail. Finally, let us talk about what psychology attempts to
understand. So psychology basically attempts to understand two things, mind and
behaviour and the questions in psychology that are asked around this
dichotomy are, what is mind, and what is behaviour okay.
Let us kind of take a
bit of a person and ask these questions What is the mind what are the functions of
the mind or how does one really study the concept called mind. This probably
is These three questions basically form the core of the topic or core of the
topics in cognitive psychology that we will be focusing on in this course.
So let us move from here and let us ask a
question What is cognitive psychology? What are you going to study in this
course? What am I going to talk about in the coming lectures?. Cognitive
psychology is been simply defined as a science is basically defined
as a branch of psychology that is devoted to the scientific study of the mind
okay.
What is mind? You
remember we ask this question. So let us actually move on, you know to a simple
definition. Let us try to construct a simple definition of what the is mind. Please
note the following instances, the use of this term called mind. I will take out
I will actually say some sentences, one of them say for example, he was able to
call to mind, what he was doing on the day of the accident.
In this sentence, you
see that the person is referring to the mind as memory. You know the person is
actually trying to bring to mind or recall what is involved in that
particular accident. Let us take the second sentence, If you put your mind to
it, I am sure you can solve that maths problem. In this case, you see the person
is actually taking mind as a problem solver.
So the mind must be
able to help you solve particular problems, the mind must be able to help you
make specific decisions, have a specific algorithm take specific steps
and then reach a final goal. Moving on, I have not made up my mind yet, say for
example I am of two minds about this. This is basically again an instance in
which the mind is being used to make decisions or consider or evaluate
possibilities okay.
So this is again one of
the functions of the mind. Another sentence here could be he is off sound, mind
and body or when he talks about his encounter with aliens, it seems like he is
out of his mind okay. Here you can see that the sense is that a healthy mind is associated with normal functioning and non-functioning is associated with abnormal functioning.
Now these are two
different things parts of which we will definitely touch on in the scores, but to
tell you that basically the mind then means something capable of
making good decisions or saying something that helps to connect with reality. So what exactly then we know about the mind.
Let us based on the statement we actually heard let us train in constructing a basic definition of
mind. A simple definition would be the mind creates and controls mental
functions such as perception, attention memory, emotions, language, deciding,
thinking, and reasoning. Now all of these terms basically are different mental
functions which we will talk about in more detail in the coming lectures.
Also, you can look at the mind as a system that creates representations of the world. So that we
can act within it to achieve our particular goals. So the mind is also motivated
resorts. You will probably touch on this definition as well when we go
to further lectures. We talked about these different mental functions, so
let us ask what these different mental functions are.
To understand what
these different mental functions are let me take you to a practical example
okay. So take a moment to read what is here and analyse it to be done along with you.
So as Raphael is walking across the campus talking to Susan on his cell phone
about meeting at the student union later this afternoon, he remembers that he
left the book that she had lent him at home.
I cannot believe it he
thinks, I can see it sitting there on my desk, where I left it. I should have
put it in my backpack last night when I was thinking about it. As he finishes
his call with Susan and makes a mental note to be on time for their
appointment, his thoughts shift to how he is going to survive after Wednesday
when his car is scheduled to go into the shop.
Rending a car offers
the most mobility, but is expensive. Bumming rides from his roommate is cheap but is rather limiting. Perhaps if he picks up a bus schedule at the student
union, he thinks, as he puts his cell phone back in his pocket. Entering his
anthropology class, he remembers that an exam is coming up soon.
Unfortunately, he still
has a lot of reading to do, so he decides that they will not be able to take Susan
to the movies tonight as they had already planned. Because he needs time to
study, as a lecture begins, Raphael is anticipating, with some anxiety his
meeting with Susan. And how he is going to tell her about this decision.
Now you see this is a
description of a lot of small little things that are happening at one
particular moment in somebody’s mind. You can actually put yourself in the
situation at any point in time or throughout the day you can pick up yourself
and just examine one such instance you will realise that at one particular
point in time a lot of different things are going on through your mind.
So let us try and see
what all is happening here, what all the mental functions are taking place.
This is the figure of what different things Raphael is doing as he is walking
across the campus, so we will see that is understanding the conversation because
he is on the phone. He is visualizing his book on the desk that he left, he is
thinking that he has to be on time for the appointment because that will
lead to complications.
He is also remembering
Susan’s book. By the way, he is walking on the campus. So he is actually presuming
the camp as well to avoid bumping into people and falling off Also you
saw that he was thinking about his car problem. So he is doing a variety of
things, he is doing, he is basically engaged and we call complex behaviour at
this point in time.
So what all is Raphael
doing actually let us boil out to that. He is presuming his environment, he is
basically seeing people on campus walking. He is also listening to Susan
talking on the phone. He is paying attention to one thing after the other
person approaching is left what Susan is saying and how much he is left for the
class.
So he is actually
paying attention to these different facts at the same time while he is involved
in this conversation on the phone. Also, Raphael is remembering, he is
remembering things from the past when he told Susan that he was going to return
her book today, he is thinking of how he will get the book back or say for
example, how he left the book on his table.
Those kinds of things
he is actually going through in his memory. He is also doing something
interesting, he is distinguishing different items in a category. When he thinks
about different possible forms of transportation, he actually is comparing
these possibilities to whether he should take a rental car, whether he should take help get a ride with his roommate or for example, he should go on
the bus.
He is actually also
evaluating possibilities in here also he is visualizing. He is basically
thinking of where he had left the book on his desk, he can actually see Okay I
left the book there, I just forgot to keep it in my backpack while I slept
in the last night. He is understanding and producing language something very
complex is actually thinking to himself understanding what Susan is saying and
also answering her back.
) So he is doing these
three things at the same point in time. He understands whatever Susan
saying, and whatever he is thinking and he is actually producing language when
talking about Susan. Also, you saw that Raphael is working to solve a problem
as he thinks about how to get to places while he is car is in the shop.
He actually has a
problem attending and while to conversation is definitely going on, he also needs
to evaluate these different possibilities. Finally, he actually comes to a
decision, so decision-making is also involved here. He has decided to postpone and
he is going to the movies with Susan tonight because he has to prepare for the
exam that is going to come afterwards.
So you will see in a
particular moment in time, we are involved in a variety of mental functions. We
are involved in a variety of these different decisions we have to take, and we are
also doing a lot of things at the same point in time. While you watching this
lecture on your laptop or your computer, you are actually doing the same thing
as Raphael is doing in this particular example.
You are remembering
something, you are pursuing the video you are listening to the audio trying to
understand what I am saying also thinking to yourself, You were also making
decisions on whether say, for example, to continue where you like the course or
whether you do not like it. Those different kinds of things you are doing at
this same moment.
This basically is what
is the crux of cognitive psychology. This is basically what we are going to study
in the coming lectures. So if this interests you it might actually help to hang
on. Now let us come to the end, let us try and talk about whether and what
cognitive psychology actually does. Let us take into account the earlier
definition of cognitive psychology
The definition of what the mind is and the definition of mental functions and we can conclude that
cognitive psychology is the study of mental functions okay. Is the study of
mental functions for example, attention, learning, memory, visualization or
mental imagery, it is a study of language, it is a study of problem-solving
when you have a problem at hand.
It is also the
study of decision-making. So in cognitive psychology, these are the
different topics, these are basically the names of the different chapters
Actually we are starting in more and more detail okay. Each of these are
specific cognitive function and we will actually look into how de study
these different cognitive functions, what are the different ways of
understanding these cognitive functions and so on.
So with this in mind, we
will actually go on to the next lecture next time which is basically going
to be about the history of cognitive psychology. We will talk about what is the
history of thought which basically called cognitive psychology. We will
actually look into a bit of the history of psychology, and how psychology develop from
philosophy.
We will also look into
how cognitive psychology or this cognitive perspective of psychology
emerged from the earlier schools of psychology.
Summarize
the following in bullet points
·
Psychology's definition varies; some view it as predicting behaviour,
reading minds, or shaping behaviour.
·
Psychology studies mental processes (e.g., learning), experiences
(subjective feelings), and behaviours (responses to events).
·
Psychology distinguishes from common sense, using scientific methods to
understand the mind and behaviour.
· Cognitive psychology examines mental functions like perception, memory, emotions, and decision-making.
That is all we will see
you in the next class.
