AutonomicNervousSystemSympathetic and
Parasympathetic Divisions are shown.
Sympathetic Promotes energy expenditure,
activated by emotion and stress (e.g. increases
heart rate, blood pressure)Parasympathetic
Promotes digestion and excretion (e.g.,
stimulates salivation, stomach and intestinal
activity can be activated by severe stress

AutonomicNervousSystemSympathetic and
Parasympathetic Divisions are shown.
Sympathetic Promotes energy expenditure,
activated by emotion and stress (e.g. increases
heart rate, blood pressure). Sympathetic action
also activates the adrenal medulla, increasing
release of adrenaline and noradrenalin (EPI and
NE)Parasympathetic Promotes digestion and
excretion (e.g., stimulates salivation, stomach
and intestinal activity can be activated by
severe stress

Retroactive and Proactive Interference
You forget some Spanish because you are learning
French.
You have difficulty learning French because of
your memory for Spanish.

Types of Memory
EXPLICIT MEMORY (also known as declarative
memory, or knowing that)
IMPLICIT MEMORY (does not depend upon concious
recollection)
EPISODIC MEMORY (memory for an event that
occurred)
PROCEDURAL MEMORY (knowing how motor
skill Learning operant conditioning)
SEMANTIC MEMORY (knowledge of factual Information)

Amnesia memory impairment resulting from trauma
or disease

• Retrograde Amnesia
• loss of memory for
• events that occurred
• before the brain damage
• ltltlt-----------time of damage------------gtgtgt
• Anterograde
  Amnesia
• 
  difficulty in learning
• 
  new information after brain damage
