Physiology and Behavior
(P&B 5)
Examine one interaction between
cognition and physiology in terms of
behavior. Evaluate two relevant studies.

Prosapagnosia


Inability to recognize faces, including your own
face.
Facial Recognition occurs in the part of the
brain known as the fusiform gyrus.


Damage to this part of the brain leads to
Prosapagnosia.
People with Prosapagnosia can still recognized
people but through other ways.

Hair style, Clothes, Voice, Situation, Location,
and more.
Schachter & Singer (1962)


Two-factor theory- emotion is a function of both
cognitive factors and physiological arousal.
184 males were injected with epinephrine, a
hormone that produces arousal.


Symptoms including: increased heartbeat,
trembling, and rapid breathing.
The participants were told they were being
injected with a new drug to test their eyesight.
Schachter & Singer (1962)


One group of participants were told the
symptoms of the drug, while the others were
not.
The participants were put in rooms with
participants who were actually confederates.

The confederates either acted happy or
angry.

Participants who were not informed of the
symptoms were more likely to feel
happier or angrier than those who were
informed.
Schachter & Singer (1962)

The Participants emotions, happy or angry,
were influenced both by how the confederates
around them responded and also by their own
mindset by being told the symptoms that would
occur.


Mediation influence on cognition.
8 Buddhist monks and 10 volunteers who had
been trained in meditation for one week,
meditated on love and compassion and were
put in a PET scan.

The Buddhist monks and two of the
volunteers had raised amounts of gamma
waves in their brains.

Gamma waves have been linked to
higher reasoning faculties.
Richard Davidson (2004)



When the participants stopped meditating, all of
the 10 volunteers' gamma wave production
returned to normal
The Buddhist monks, how meditated for 10,000
hours to reach the rank adept, did not have their
gamma wave production return to normal.
The monks' gamma production during
meditation was found to be larger then the
volunteers' production.
Richard Davidson (2004)


Davidson argued that meditation could have
significant long-term effects on the brain and the
way it processes emotions.
The findings of this experiment indicate that the
brain adapts to stimulation.

Whether from the environment or as a
result of our own thinking.
