Motivation is the process by which activities are started directed, and continued so that
physical or psychological needs wants are met. The world itself comes from the Latin word
‘movere’, which means “to move”. Thus motivation is what ‘moves’ people to do the things
they do.
MOTIVATIONAL CYCLE:
Motivational cycle is a transition of states within an organism that propels the organism
towards the satisfaction of a particular need. The motivation cycle begins with a need. A
need is the absence of some necessity. The next state is drive, which is arousal and
energizing. The activity is a goal directed behaviour that continues till until the person
reaches that goal. Arousal is then reduced as a result of the cycle. After a person’s next
need arises, the cycle repeats itself, and the same pathway is followed. There are four
aspects of Motivational cycle. They are:
1. Need:
A need is lack or deficit of some necessity. It’s a state of physical deprivation that causes
tension within an organism. The tension caused when the organism is deprived of basic
necessities of life as food, water, and sleep, causes the internal environment of an
organism to be imbalanced. The imbalance caused by the need arouses the organism to
maintain its balance. For any goal directed behaviour, need is the first condition or
stimulating factor. While some people may have simple, primary needs such as food,
shelter, clothing, sex etc, some may have secondary needs such as affiliation, power and
achievement.
2. Drive: Need leads to drive, which is the second step towards achieving goal. Drive can be
defined as the state of tension or arousal produced by need. The drive can also be
considered as the original source of energy that activates an organism. For instance, when
an organism is hungry and/or thirsty, the organism seeks to reduce this drive by eating
and/or drinking. Drive acts as a strong persistent stimulus to push an organism towards its
goal.
3. Incentive: The object of the environment that activates, directs, and maintains behaviour is
called incentive. The incentive theory understands incentives as the motivation, which a
person has to achieve any particular goal object. The motivated behaviour is directed
towards incentive and getting closer to the incentive provides satisfaction of the aroused
drive. For example: Behaviour like eating food is an incentive that reduces the drive of the
person caused by the need to fulfil his hunger. The reduction of behaviour then cuts off
and restores balance in an organism.
4. Goal/Reward: The reduction of tension in the body can be considered as the goal of any
motivated behaviour. A hungry man eats food, and his body restores to a balanced
condition. This then reduces the tension. This reduction of tension as a result of an
energized activity is called goal. Once the goal has been completed, the organism is again
ready for another goal-motivated behaviour.
These four steps continue on and on throughout the life-course of an organism. Because
the needs are never ending, it leads to drive, which then lead to incentive and the goal.
For Example: The motivational cycle of the hungry man is over once when he eats and the
goal is satisfied. But, the cycle will restart once the man gets hungry again. The cycle goes
on and on only to end at the demise of an organism, at which point, the needs
permanently stop. Motivational cycle means that behaviour goes on in a sequence.
BIOGENIC MOTIVES:
Biogenic motives are called as physiological motives or primary motives. These motives
are essential for the survival of the organism. Such motives are triggered when there is
imbalance in the body. The body always tends to maintain a state of equilibrium called
“Homeostasis”- in many of its internal physiological processes.
1. Hunger:
Hunger is satisfied by food. Glucose or blood sugar is believed to be an important
substance in the initiation of hunger motivation. Low rates of Glucose use are correlated
with reports of hunger and high utilization of glucose, such as just after the meals is related
to satiety – the absence of hunger. Feelings of hunger are also controlled by the
Hypothalamus in the brain. Although in animals hunger is controlled by biological factors to
a large extent but in human beings, with biological factors several other external conditions
also influence eating behaviour. The taste, aroma, presentation of food, company of others
influence us to a very large extent. The type of food which satisfies hunger also varies
from culture to culture.
2. Thirst:
Thirst typically drives us to drink water. It was believed that dryness of mouth arouses
thirst, but thirst is quenched even when water is poured directly into the stomach. Thus,
dryness of mouth is merely an indicator of thirst. Thirst motivation and drinking is triggered
by two conditions in the body
I. Loss of water from the cells dehydrates the cells, thereby signalling the person to drink.
II. Loss of water from the body also results in reduction of blood volume, which in turn
lowers the blood pressure. This stimulates the kidneys and through the secretion of certain
enzymes, thirst is triggered.
3. Sex:
Sex is a unique motive because it is very powerful in directing the behaviour of the
individual, but it is not essential for the survival of the individual, although it is necessary
for the survival of the species. The physiological basis of sex is the secretion of sex
hormones. The testes of the males and ovaries of the females produce hormones which
are responsible for sex desire. In human beings, sex hormones have a partial role to play.
Learned habits, likes and dislikes, cultural practices play an important role. The sex motive
is not aroused in the presence of just any member of the opposite sex even though sex
hormone is present. Many sexual disorders have a root cause in psychological factors
rather than the physiological ones.
4. Sleep:
All other motives push the person to do something, they make the organism active. Sleep
is a physiological motive which involves passive resting of the body, rather than active
striving. It is a necessary state for the body as the process of body repair and building up
of the body takes place when the person is sleeping. Earlier it was believed that
accumulation of waste products in the body makes the person sleepy. But research has
indicated that sleep is regulated by certain segments in the brain.
5. Pain Avoidance:
This is a powerful motive as it stimulates the organism to look for the ways to relieve pain
or escape it. If a rat is given shock for entering the wrong path in a maze, the rat will learn
to avoid that wrong path. Free nerve - endings widely distributed throughout the skin,
blood vessels and internal organs are receptors for the pain.
SOCIOGENIC MOTIVES:
They are learnt in social groups as a result of interaction with the family and society. That
is why their strength differs from one individual to another. They help to determine much of
what a person does, they tend to persist, are not fully satisfied and no sooner one goal is
reached, the motive gets directed towards another one. For example, the need for
affiliation – the need to make friends is not limited to few friends, but results in making
several friendships, in a variety of situations.
a) Every human being has a different set of needs and unsatisfied needs act as strong
motivators.
b) As every individual has many needs, they are arranged in the order of their importance
starting from most basic need to most complex needs.
c) The individual moves to the advanced level need only when the basic need is satisfied.
If basics needs are not satisfied, the higher level needs will be postponed.
d) There are five basic needs and human beings tend to satisfy them in the order of their
hierarchy.
e) A satisfied need does not act as a motivator, only unsatisfied need continue to motivate
a human being.
f) Physiological and safety needs are finite in nature but higher level needs are infinite in
nature.
g) Various levels of needs are overlapping.
1) Physiological needs:
These needs include the most basic and obvious needs for survival of human beings.
These are the most powerful needs which motivate an individual till they are satisfied. The
need for food, water, oxygen, sleep, shelter, air etc may be categorised as physiological
needs. This category of needs represent the need for basic necessities of life which are
indispensible for the biological maintenance of a human being. If any of these
physiological needs is unsatisfied, the individual will primarily strive to satisfy that particular
need and will forget about other higher level needs. For example, a hungry person will
never seek any luxury of life or dream of building a new world until his need for food is
fulfilled.
2) Safety or security needs:
Safety needs are next in the hierarchy of needs given by Abraham Maslow. Once the
basic needs of an individual are satisfied, he will strive for fulfilment of second level of
needs which are popularly known as safety or security needs. Safety needs here
emphasise upon an assurance of continuity of job, security of source of income, provision
for old age, insurance, prediction of environmental factors surrounding an individual etc.
3) Belongingness needs:
Affiliation or belongingness needs are at the third level of need hierarchy. When
physiological and safety needs of a human being are met, he starts putting efforts to
satisfy his belongingness needs. These needs represent the need for love, affection,
friendship, membership in groups, social acceptance etc.
4) Self-esteem needs:
Fourth level of need hierarchy is called self esteem needs. These needs are concerned
with self respect, self confidence, recognition, appreciation, prestige, power etc. Esteem
needs represent the typical human desire to be accepted and valued by others. Fulfilment
of these needs give a sense of self worth and ego satisfaction. For example, in an
organisational context, esteem needs are satisfied by job title, recognition by leader,
challenging work, responsibility, performance feedback and participation in decision
making etc.
5) Self-actualisation needs:
At the top of the hierarchy of needs is need for self actualisation. These needs represent
the need to be what a person is capable of becoming. This need constitute an individuals’
mission of his life. An individual who has satisfied all levels of his needs tries to fully utilise
his talent, potential, skills and capacities. This need signifies a person’s desire of personal
achievement. The sense of personal achievement leads to sense of psychological
satisfaction.
FORGETTING
Forgetting refers to the inability to remember or recall something previously learned.
CAUSES OF FORGETTING:
Proactive interference: It occurs when you cannot learn a new task because of an old task
that had been learned. When what we already know interferes with what we are currently
learning – where old memories disrupt new memories.
Retroactive interference: It occurs when you forget a previously learned task due to the
learning of a new task. In other words, later learning interferes with earlier learning –
where new memories disrupt old memories.
FORGETTING CURVE
The Ebbinghaus forgetting curve is a graphical representation of the forgetting process.
The curve demonstrates the declining rate at which information is lost if no particular effort
is made to remember it. The forgetting curve was defined in 1885 by German psychologist
Hermann Ebbinghaus in his book Memory.
Rate of forgetting: Ebbinghaus found that the forgetting curve is exponential in nature. It
starts off very steep—the amount of retained knowledge drops dramatically soon after we
acquire new information. In fact, most of the forgetting occurs within the first hour of
learning. And that’s not all. After a day or two, we typically forget around 75% of what we
have learned.
There is a point at which the forgetting rate starts to decline at a slower pace. After a day
or so, it usually levels off. This is when we can partially absorb essential details and store
them in our long-term memory. In other words, the day after taking a course, we will retain
only a few details but we will be able to remember them for several more days.
Contributing factors: According to Ebbinghaus, the basic forgetting rate doesn’t differ
significantly between individuals. Still, this rate can be influenced to a certain extent by
different factors.
S-O-R MODEL:
The S-O-R( stimulus organism response) theory states that there’s a stimulus that triggers
a response based on the internal feelings or behaviour of an organism (person). This
internal processing of the stimulus can be conscious or unconscious. It further triggers an
emotion that leads to a response. The resulting response can be internal, like an
increased heart rate, or external, like crying.
