As we’ll discuss in this lesson,
there are good stressors and
bad stressors. Although there
are some standard responses
to stress, everyone tends to
exhibit different signs and
symptoms.
Stress
Fight-or-Flight Response
A standard physical response to
stress is known as the fight-or-flight
response. The fight-or-flight
response is the activation of the
sympathetic nervous system that
prepares the body to challenge or
flee from a perceived threat.

Effects of the Fight-or-Flight Response
include:

system
� Increased heart rate
� Increased breathing
� Adrenalin released into the
bloodstream
Stress
Stress and the fight-or-flight
response can lead to various
physical, emotional, mental,
and behavioral symptoms.
Individuals differ as to which
signs they typically
experience during stress.

A stressor is any event that is
perceived by the individual to be
stressful. Stressors are subjective; this
means that they differ from person to
person. What one person thinks is
stressful may not be stressful to
another.

Psychologists Yerkes and Dodson
studied the effects of stress on
performance.
The results are now known as the

Stress that increases
performance is known as
eustress, or positive stress.
Eustress is why Shawn, the
soccer player, likes stress.
Eustress can help you
perform better on tests or
become physically stronger. It
occurs when there are
positive changes in your life,
such as getting married.

Distress is negative stress.
Distress occurs when we have
more stress than we are able
to cope with.

For Shawn’s teammates,
getting so stressed before a
game could be more than
they can handle. Therefore,
although it is eustress for
Shawn, it would be distress
for his teammates.
