3 Narcissism
Component 1
Summary and Analysis
Narcissism is based on the Greek Myth Narcissus who feel in love with his own
reflection and was later identified as a personality disorder (Jenkins, 2019). Narcissistic
Personality Disorder or NPD are long term patterns of abnormal behavior, exaggerated feelings
of self-importance, and excessive need for admiration and showing a lack of empathy for other
people. This can only be classified as a disorder if this is more than people would generally
expect to see in standard human behavior.
While most people think a narcissist is just someone who thinks they are the best at
everything, it is exceedingly much more than that. A narcissist is someone who develops a made-
up or false self in order to avoid seeing their real self, which they often believe to be dreadful and
un-loveable (Jenkins, 2019). Someone with narcissistic personality disorder expects to be
recognized as superior even if they do not do anything astoundingly well, they require excessive
admiration, and have a sense of entitlement. They can also take advantage of others in order to
get what they want. People with narcissism do not do things for others unless there is an
immediate gain or recognition for themselves by helping someone out.
In order for an individual to be diagnosed with Narcissistic Personality Disorder, or NPD,
they have to preset with at least five of the following characteristics: the need to make-up skills
or talents to help them achieve in their life, they need to have others see their perfect lives, they
belief that they are superior to others around them, they need to be told how wonderful they are,
they believe that they should be treated with the highest respect and given material items when
they go places, they have no problem using someone to get what they want, they cannot relate to
4 Narcissism
others, they get exceedingly jealous of others relationships, and they believe that they are the
only one who can solve problem with getting the creating answer to do so (Jenkins, 2019).
Humans have a need for admiration and will have times of self-importance, and will
occasionally lack empathy for others, but as long the characteristics and traits are within the
typical range and not an exceeding amount, there is no need to worry, especially if there are signs
in younger children. Narcissistic Personality Disorder usually develops in adolescence or during
early adulthood. It is not unusual for children or young adults to display signs or traits similar to
those of NPD.
Narcissism is a big deal today due to the increased pressure on kids to achieve greatness.
When we tell adolescents that they need to do better, give too much praise, or belittle them,
adults will start to create narcissistic thoughts about themselves. When parents tell their kids that
achievements are defined by getting good grades, getting into the best college, and getting the
best job, then they the focus of thought is on the ones self and they see will start to see others as
merely objects. If the sole purpose of a child’s life is too building a prolific portfolio of
themselves, then of course a child is going to grow up only looking out for themselves and have
vastly little to no concern for others.
A few things I had wondered when watching Dr. Paul Jenkins video was if there was a
way that we could teach children to get along and help them see from another person’s point of
view and since we start to see the changes in adolescents, does that mean that narcissism can
evolve with age? Babies, young children, and adolescents need us for survival, but it is up to the
parent as the child gets older to be empathetic and think about others around.

Component 2
Research Application
Adolescents are stereotyped as overconfident, less hardworking, callous, emotionally
unstable, dishonest, and most commonly as narcissistic. In recent years, researches have begun to
reevaluate whether young adults, today, are more narcissistic than older children and adults from
another decade. In a world full of change, why would anyone expect narcissism, to not change
across one’s life span?
Aside from the fact of how narcissism changes within an individual’s own life is whether
people in more recent history report higher levels of narcissism. “People from more recent
history are higher in narcissism, lower in empathy, higher in attachment avoidance, use more
positive self-evaluation statements, and display more problematic or narcissistic behavior”
(Chopik & Grimm, 2019). American culture creates narcissism by the books, songs, magazine
and newspaper articles, and even political debates. It has been speculated by researches that these
differences are coming from different sources, including changes in the way parents raise their
children, how cultural norms have changed, and how the introduction of technology (Chopik &
Grimm, 2019).
In the study done by W.J. Chopik and K.J. Grimm they started by looking at other studies
in the past. The data sets that Chopik and Grimm looked at most commonly used the personality
data from the Block and Block Longitudinal Study of Cognitive and Ego Development or
otherwise known as the Block and Block Study. The Block and Block Study examined
personality and cognitive development from childhood to early adulthood for a sample of 128
children (Block and Block Longitudinal Study, 2006). In two samples Chopik and Grimm looked
at, the ages from one study was 43 to 53 and the another was from the ages 34-59. Another
6 Narcissism
sample that W.J. Chopik and K.J. Grimm looked at was a data sample from the ages 14-23, but
this sample did not examine rank-order and mean-level change across the assessment points in
concert with other data sets. Chopik and Grimm wanted to examine the longitudinal changes in
four studies of narcissism to draw a picture on how narcissism can change throughout one’s life
and even throughout history.
The first study that W.J. Chopik and K.J. Grimm looked at was the Block and Block
Longitudinal Study from 1968. The study consisted of 107 participants and over 50% of the
partakers were female. The ages collected from this data were 14, 18, and 23, with the ethnic
make-up was “68.3% Caucasian, 24% African American, 4.8% Asian American, and 2.9% other
ethnicities” (Chopik & Grimm, 2019).
The next study Chopik and Grimm examined was the Intergenerational Studies
comprised of 354 individuals and this study consisted of a 53.7% female participants. The
Intergenerational Study was an umbrella study, combining studies from Berkeley Guidance
Study, Oakland Growth Study, and Berkeley Growth Study (Chopik & Grimm, 2019). The three
studies spanned from the years of 1920’s to the 1930’s. The Berkeley Guidance and Growth
Studies collected samples from infants babies in the years spanning from 1928 to 1929, while the
Oakland Growth Study began in 1932 and sampled children in fifth and sixth grade classes.
Participants from the Berkeley Growth and Oakland Growth Study were all Caucasian and only
3% from the Guidance Study were African American.
The third study was from Mills Longitudinal Study conducted in the years of 1958 to
1960. There were 112 participants from the senior class at Mills College in Oakland, California
ranging from ages 21 to 43. The study was predominately composed of Caucasians, while the
7 Narcissism
accurate percent of other racial/ ethnic groups were not available. Over 60% of the participants
had earned a certificate or graduate-level education (Chopik & Grimm, 2019).
The last study Chopik and Grimm examined was the Radcliffe College Class of 1964. All
176 participants were female and was collected from Radcliffe College in Cambridge,
Massachusetts. The ages collected from the study were between 42 and 72 and all but one
woman was European American (Chopik & Grimm, 2019). Over 80% of the woman from this
sample had completed a selection of graduate-level education. A combination of the samples
concluded that the average age being sampled was 39 years, over 70% were female, and there
were over 2,282 observations conducted.
In order for Grimm and Chopik to examine whether or not narcissism changes throughout
our life span, they used a growth curve model in the SPSS Mixed command, which was
comprised of hypersensitivity, willfulness, and autonomy. This allowed them to model
intraindividual changes and moderators of these changes (Chopik & Grimm, 2019). Their theory
of if birth cohorts changed in narcissism was addressed in three ways. The first birth cohort was
examining the differences between an exploratory fashion in the context multicultural models.
The second was a contrast between historical time and narcissism while controlling the age. The
final way was to look at birth year differences in other geographical location to spot a detailed
pattern of historical changes in narcissism (Chopik & Grimm, 2019).
As a final result the ages examined for changes in narcissism were from 13 to 77.
Subsequently the results of the analysis were, hypersensitivity was declining across our life span,
mainly seen after the age of 40. Willfulness was declining across our life span, were men are
higher in willfulness than women. “Decomposing this interaction revealed that women
experienced the greatest declines in willfulness during young adulthood; men experienced slight
8 Narcissism
increases in willfulness early in the life span before declining in later life” (Chopik & Grimm,
2019). Results of autonomy was increasing over our life span. “Decomposing this interaction
revealed that women had sharper increases in autonomy across the life span, especially after
middle age, albeit this effect was small” (Chopik & Grimm, 2019).
Grimm and Chopik found that while hypersensitivity and willfulness declined through
life and autonomy increased, they did find that later born cohorts were lower in hypersensitivity
and higher in autonomy, which is agreeable to their theory of narcissism changing throughout
history. “Because gender was associated with narcissism in the current study and in past work,
we concluded it as a covariate and moderating variable of age-related changes in narcissism”
(Chopik & Grimm, 2019). In Chopik’s and Grimm’s updated study there was no consistent or no
variables to operationalize changes in the variables, which left them with simply informative data
on how narcissism can change.
For the future, I would like to see a more recent study and a better ethnical range, age
range, location range, and how the participants grew up. I think a big part of narcissism can come
from how a person grew up and where the person grew up. With autonomy increasing, people
high in autonomy might live in environments that are beneficial to supporting their lifestyle and
have less changes of someone dulling their positions. From my standpoint, if researchers
examined and restudied this theory, they might find some surprising results. We live in the most
advanced time and I can only assume that narcissism has only grown with the progression of
social media.
9 Narcissism
Component 3
Theory 1: Nature-Nurture theory
There is a saying out there that some masterminds, whether that be a musician, an artist,
an athlete, or a politician, are “born, not made”. In some ways that leads true, but our DNA
imprints significantly holds what our personalities and even our talents will be. Nevertheless,
some of these traits we not “born” in us, but can be created in us.
Narcissism may be an outcome from the complex interactions between genes and the
environment. The thinking goes that people contrast in their genetic make-up and have a grander
or minor potential to become narcissistic. However, environmental aspects can help influence the
expression of narcissistic tendencies. From this outlook, people who are genetically susceptible
to narcissism will change if, for example, they are raised in a surrounding in which their
caregivers lack sensitivity. People who naturally lean toward confidence or liveliness will
become narcissistic if their caregivers are not in tune to their needs.
Narcissism is based on two beliefs attributed to infants, omnipotence and limitlessness
(Carlson, Vazire, & Oltmanns, 2011). Before birth, we use up the better part of our first year
living in an environment intended to accommodate to our every need. This provides our first year
of life with everything a developing person needs and then we are advanced out of this safe
space, that was created of us, into a world that is extremely different from what we had
previously known before. At no other time in life can the strength or the shortcomings of a
person have so much influence as when a caregiver takes on the role of the sole role model to a
child solely dependent on them for their very need.
A baby cries and their needs are met. With time, babies learn that a quick response may
not come, but that their caregivers will attend to them gradually as seen fit for the situation. This
10 Narcissism
cycle can create a bond of trust and acknowledgment between the caregiver and the baby
(Carlson, Vazire, & Oltmanns, 2011). This is healthy and crucial for the development of a healthy
self-worth and the ability to engross in a mutually pleasing adult relationships.
We learn that omnipotence, unlimited or great power, is impossible and that we face
personal limits in our relationships. We are able to recognize that we need others to meet our
needs and that our behaviors must conform to the situations that we are in, in order to getting our
desires met. This is about creating a balance of separateness, togetherness, and mutual support. It
sounds simple, but narcissists have put up solid walls that protect them from absorbing these
realities.
Admittedly, it can be crushing to even the most emotionally well-balanced person to
suddenly be in charge for the survival of another. Some people, however, cannot rise to the
challenge due to the limits of their own emotional development. Thus, when an infant is unable
to develop trust and to accept that her caregiver will meet their needs, unpleasant consequences
can result. Without learning about the limits of power and control within a healthy early
relationship, the desire to control others and command the disbanding of another’s personal
boundaries circumscribes can hinder their efforts at developing successful relationships in
adulthood.
It seems that excessive praise and excessive criticism can both cause a child to develop
narcissistic personality traits once they reach adulthood. “Some people seem to model the
attitudes and behavior of narcissistic parents, while still others react to childhood neglect by
becoming very self-centered and independent in adulthood” (The Ranch, 2017). Mental health
professionals who analyze narcissistic personality disorder causes are unanimous in concluding
that genetics, parental exposures, and other environmental influences combine to produce adults
11 Narcissism
who exhibit narcissistic personality characteristics. Erik Turkheimer stated that it is difficult to
find clear-cut answers to the nature-nurture because it takes researchers back to the bigger
question of relationships with the natural world (Turkheimer, 2020). People may be born with
certain predispositions to narcissism, but if they have stable and happy childhoods those potential
traits are far less likely to manifest.
The latest lifespan-based research based on Grimm’s and Chopik’s research on how
narcissism changes from adolescence to older adulthood is noteworthy because, unlike a large
amount of studies on narcissism, Grimm and Chopik did not rely on cross-sectional samples,
which only offer a snapshot of narcissism over a short period of time. Which can only lead me to
believing that the number is much greater than what their research shows us.
Theory 2: Psychoanalytic theories
The psychodynamic model of narcissism is led by two overlapping sets of thought, the
self-psychology school and the object relations school (Narcissism: Psychological Disorder,
Theories, Treatment, n.d.). The self-psychology school suggests that narcissism is a component
of everyone’s psyche. We are all born as narcissists and gradually as we grow up to adults,
narcissism matures into a healthy adult narcissism.
A narcissistic disorder results when this process is somehow interrupted. “By contrast the
object relations school argues that narcissism does not result from the arrest of the normal
maturation of infantile narcissism, rather a narcissism represents a fixation in one of the
developmental periods of childhood” (Narcissism: Psychological Disorder, Theories, Treatment,
n.d.). Specifically, the narcissist is fixated at a developmental stage in which the differentiation
between the self and others is blurred.
12 Narcissism
Freud believed that early childhood experiences held high importance on the
development of personality and that analyzing the harms of the past could unlock a person’s
development later in their life (Thompson, 2019). We have seen time and time again that parents
spoil their children and trying to mold the child into someone that the parent could not be. In this
regard, this is making the child responsible for the frustrations and the deepest desires of the
parent’s ego. That is why when Freud talked about the unconscious mind, narcissism and
projections, the parents love becomes more of a love for themselves and how they believe they
were as a child or how they wished they would have been. To the child, this is seen as a normal
loving relationship, they do not know any different.
The father or mother who projects narcissistic tendencies onto their child does not want
their son or daughter to lack what they longed for or desired. In turn, they see in their children
the perfect representation of their ideal self. It is possible that the narcissism that the parent is
unconscious or that at least the parent never explicitly responses on this behavior.
In some scenarios, children may reflect these tendencies in different ways. Sometimes,
they assume the roles that were “assigned” to them, generating disorders that affect them later in
life, and which will make them rebel later because they feel abandoned.
As a result, insecurity in one’s own worth and agency arises. Insecure attachment to a
parental figure can hinder the child to properly navigate through the perilous waters of early
childhood development (Epstein Mind, 2019). The child’s mind will start to feel shame for the
pain they are suffering from. The shameful feelings display an issue with shortage which the
child will struggle to fight off. These feelings of low self-worth torture the child deserting them
feeling “wrong.” The feelings of shame, guilt, and isolation leave them feeling like an outcast as
no one can seemingly relate to their struggle and force them into a very self-protective position.
13 Narcissism
This feeling of abandonment is due to the unassuming reason that the relationship between the
child and the parent does not exist. In this regard, the child can set in motion of controlling
others.
Theory 3: Trait Theory of Personality
Narcissistic personality is characterized as showing an overwhelming need for admiration
and attention, lacking empathy, and feelings of grandness (Merriam-Webster Dictionary, n.d.).
Narcissists tend to make friends quickly, but they will have an extremely hard time keeping these
friendships due to the fact that they think they are never wrong. Narcissists tend to be attracted to
leadership positions and it is likely that these characteristics that facilitate a narcissistic
individual can be a leader, which could potentially lead to being a destructive leader. Narcissistic
predispositions make it unlikely that narcissists will successfully engage in leader development.
Narcissists tend to be sensitive to criticism, so having someone with narcissism associated with
a leader position can lead to resistance.
Another important element of leader development is that it serves as an opportunity to
develop common assets, principals, and investments, within the organization. It could be possible
that a strong narcissistic personality in the program could hinder the developmental progress of
other program participants. In general, narcissists tend to exploit others to make themselves look
better and react with rage when favors are not returned (Mayo Clinic, 2017). They feel
threatened by the success of others and tend to collect knowledge that may build another
person’s success. “In the workplace, narcissism is combined with counterproductive work
behaviors and past research indicates a relationship between narcissism and supervisor ratings of
interpersonal performance” (Senior, 2019).
14 Narcissism
Although there is little research examining the relationship between narcissism and leader
development outcomes, there is at least some evidence that narcissism and similar tendencies
decrease the effectiveness of leader development. There have been observations on the impact of
several dark triad traits, including narcissism, on leader development outcomes. In these
observations, is was theorized that narcissism would reduce the effectiveness of leadership
development, but instead it was found that traits connected to narcissism were confidently related
to leadership development outcomes.
Narcissists also appear to be socially effective due to their charm and personality.
Narcissism might represent alternative routes to social effectiveness with one being beneficial
and the other one being selfish. There is evidence to suggest that humans have evolved a number
of alternative strategies for success in life, and that each of these has its own advantages and
disadvantages. Selfish approaches tend to create resentment in other people, but people with
sharp social influence skills might still be successful in getting ahead in spite of causing
problems for other people.
The underlying basis of personality most likely consists of a number of different
dimensions that combine in a mixture of ways, rather than a specific super-factor with good and
bad extremes. Hence, multidimensional personality models such as the interpersonal circumplex
and the Big Five, which allow for a bigger variety of trait combinations, seem to provide a better
account of complex traits such as narcissism than a one-dimensional general factor of
personality.
15 Narcissism
Component 4
Personal Reflection
One of the main reasons I chose to research narcissism is because I work with at my job,
is starting to show more and more signs of having Narcissistic Personality Disorder. There has
been a lot of situations lately to where he has done things, said things, or the lack of emotion for
his wrong doing is becoming blatantly obvious. I have written a well papers in the Psychology
classes I have taken and all of the topics have been something that I have previously searched
and knew about. With this paper, I wanted to challenge myself about something I knew very little
about. So, when I was asking another teacher about topics to write about, she had mention that I
write about narcissism because of the kid that we work with.
So, to touch a little bit on the background of the boy that we help, let’s call him Chase,
for beginners Chase is on an IEP, which stands for Individualized Education Program. There are
a number of reasons on why a child may be placed on an IEP, but for Chase’s reasoning is simply
because he has annual goals he needs to meet along with daily goals. One of Chase’s daily goals
is his attitude towards the teachers and participating in classroom activities. From speculations, it
has been said that his father has never been present at any of the progress meetings to do with
Chase. A few of the faculty members have met his dad and have said that there is something off
putting about his dad and that they think they know where Chase may get a majority of his traits
from. But again, that is only speculation.
Subsequently, the lack of knowledge about narcissism is what lead me to writing my final
project. Upon learning only having a basic knowledge about NPD, I did not know what I was
going to learn and I did not have a certain view about people with NPD. My basic knowledge
16 Narcissism
about narcissism was just that they thought very high of themselves and would stop at nothing to
get what they thought they deserved. Though, what I learned was so much more than that.
For people many people they may not know that narcissism is on the rise and that raising
the future generation by nurturing them and morphing them into someone who we wished we
were and how we acted, can cause a rippling affect into how parents and caregivers can be one of
the main causes of narcissism on the rise. Whenever we, me and the sixth grade IEP coordinator,
have talked to Chase about foraging signatures, late assignments, and stealing items, you can
absolutely see it in his face for lack of owning up to what he has done and he will always have
something to say to try and make it seem like it was not him that was doing these things. He a
lack of empathy for doing anything wrong and will not own up to what he has done. After
looking in depth about NPD, his behaviors are textbook, and it is scary to see how advanced this
is for his age.
Sometimes, I do feel bad about getting onto Chase because I do speculate that there is
something more going on at home. It truly does look like he wants to try and be a better person,
but just when you think you are making a break through, he does something or says something
that leads you to believe that it is just a cover. Chase is truly a bright kid, wants to tell stories,
and have more friends, but once you peel away that mask little by little, you begin to see who he
really is. It is truly heartbreaking and I want to show him that I am hear for him, but how can you
do that when you are working with someone who is probably just going to use you to get what
they want?
I expressed earlier that I did not have much of an opinion on narcissism, but know after
doing some research, it is most defienetly concerning. I feel like interacting with a military
community has opened up my eyes and actually makes me wonder if military kids living
17 Narcissism
overseas are a little bit more narcissistic at the school age level than kids having never moved
around and going to the same school for their whole life. Helping the kids at the school, and
thinking back on some of what they have all said makes me a little more interesting in seeing
how advanced narcissism has become since some of the later studies. I do realize that all humans
can be a bit narcissistic at times, but I do question if the advancement of technology can or has
played a role on the evolution of narcissism.
Cell phones enable teens to constantly continue contact with peers, and block out
interactions with those they do not want to be in contact with. This progression may distance
teens even further from people and obstruct the process of developing healthy empathy and a
feeling of involvement in a larger community. Right at the moment in human development when
we are supposed to grow up and face reality, mobile phones, tablets, iPads, laptops, and online
gaming may shield us from us creating a healthy relationship with others.
Social networks say that they are means for a way to stay in touch, but they are creating
us to become more anti-social, by relying on the digital connection to able us to talk to someone
rather than face-to-face. If you think about it, the main benefit is limiting out interaction talents.
Thousands of different kinds of websites, from YouTube, to the news article that we read are
allowing everyone to post any sort of comment and "socialize" with other people. But only social
networks enable us to create a me-centered private club, which is what narcissistic If new
technology really does promote narcissism, then younger people would be more narcissistic
thrive off of. They can make their social media look like they live the perfect life. They have the
best job, best relationship, have money, can do what they want when they want, and most
importantly nothing is wrong in their life.
18 Narcissism
I think the most concerning thing about the evolution of narcissism is we do not know
exactly how advanced it has become. I would like to think that our advances in technology have
little to do with the evolution in narcissism and that technology is has not advanced that much
since I have been alive. However, I was born in the 90’s and I grew up in the world when cell
phones, or Apple, was hitting the market. The advancements in the last twenty years have made a
great impact on the world. I know when I was finally able to have social media, how self-
centered I was, and thinking about kids having access to cell phones as early as the age of 10, is
frightening. I would enjoy seeing a more recent study on just how far narcissism has advanced
since the 90’s or even the 80’s.
For a narcissist, having a cell phone with the ability to have everything they want within
the touch of their phone, is their ideal world. There is absolutely no doubt in my mind that there
would not be any growth in NPD. I would agree with millions of others saying that we live in the
most narcissistic time in the world.
