This presentation is about teens and their main characteristics.

2. Piaget's identified five characteristic indicators of adolescent
cognitive development and named them as follows:
 Formal operations.
 Hypothetic-deductive reasoning.
 Propositional thought.
 The imaginary audience.
 The personal fable.

3. 1° FORMAL OPERATIONS
 Piaget use "mental operations" to describe the mental ability to
imagine a hypothetical situation and to be able to determine a
likely outcome. An adolescent with the ability to think abstractly
can describe events they have never seen or experienced. This
is commonly called a "What if--?" scenario.

4.  Is the ability to think abstractly in a more scientific and logical
manner. This ability helps a person solve problems by working
on one aspect of the problem (Oswalt, 2012).
 For example, a person comes into a dark room and tries the light switch,
which doesn’t work. The person assumes that the light has burned out
and goes and gets a light bulb. He inserts the new light bulb, but it still
doesn’t work, so he checks to see if the light is plugged in. He finds that
the light is indeed unplugged and plugs it in and voila!

5.  Is the ability to make a logical conclusion based on the wording of
a statement rather than the observation of it (Oswalt, 2012).
 A good example of this kind of thinking occurs in yoga audio podcasts vs. a
yoga video podcast. In an audio podcast, the person doing the yoga practice
must rely on the logic of the words to perform the practice, whereas someone
who does not have this ability must rely on a video.

6.  Is the ability to make judgments, interpret and observe. In
adolescence
 This is acquired at a time when their bodies are changing
(Oswalt, 2012).

7.  Is also a characteristic in adolescence.
 This is where teens develop the ability to compare themselves to
others and they begin to notice their personal strengths and
weaknesses (Oswalt, 2012).

8.  Thirteen-year-old teens are dealing with the physical changes in
their body - puberty - emotionally as well as physically. This will
cause your young teen to feel uncertain, moody and be sensitive
to what others think of them, especially their peers.

9.  Fourteen-year-old teens feel pretty
happy with themselves as much of the
angst from the changes they have been
going through levels off and then have
gotten used to no longer being
a young child anymore.

10.  Fifteen-year-old teens are pushing their parents to do more and
more on their own, and they do not want to have to ask permission
to do it a 15-year-old teen is that the latter doesn't want to have to
seek your permission to do something independently.

11.  Sixteen-year-old teens are comfortable in
their own skin and know the ropes as to the
life around them. They have learned much
about themselves in the past few years and
are able to see when they are at their best
and when they are at their worst. They also
see the best and worst of their parents which
will gain you some criticisms and
complements oftentimes right out of the blue.

12.  Seventeen-year-old teens are more
in-control of their moods and emotions.
They form stronger relationships than in
the past and are able to build strong
bonds with friends They begin to see
their future and can feel both excited and
apprehensive about it. The 17-year-old teen
has less conflict with parents, but will still
push for more independence.

13.  The eighteen-year-old teen is on an
identity quest into their future. They
want to figure out where they will fit in
today's world. It is a time for big change
that comes with a lot of freedom and
happiness along with feelings of
nostalgia and apprehension.
The 18-year-old is often idealistic and
enthusiastic about their future goals .
