2) The phobic object/situation almost always provokes immediate fear or
anxiety.
3)The phobic object or situation is actively avoided or endured with marked fear
or anxiety.
4)The fear or anxiety is out of proportion to the actual danger posed by the
specific object or situation
5) The fear, anxiety or avoidance is persistent, typically lasting six or more months
6) The fear, anxiety, or avoidance cause clinically significant distress or
impairment in social, occupational, or other important areas of functioning.
7) The disturbance is not better accounted for by another mental disorder

1)Animal
2)Natural environment
3)Blood-injection-injury

Elaborate on Aetiology - Psychoanalytic Explanations, with an example (3)
1)Repressed id urges and desires that are
trying to come into consciousness
2)Phobia as a defense mechanism
3)The fear becomes associated with external
events that has a symbolic relevance to the
repressed urges
Eg: Little Hans
freud’s interpretation of little hans’ phobia of horses
Freud’s interpretation - the large size of horses - Hans
unconsciously identified with the great power of his fatherCastration anxiety
An irrational fear that the father will
castrate his penis, as a punishment
Mowrer’s two factor model
Fear acquired through
classical conditioning and
maintained through operant
conditioning
Lil’ Albert (Watson & Raynor, 1920) study on conditioning
After several pairings of the rat (CS) with a loud sound (UCS),
Albert begins to fear (CR) the rat
Biological preparedness theory
A theory which argues that we have inherent predispositions (inherited abilities) to
fear some things because they have been life-threatening to our ancestors
Non-associative fear acquisition
Fear of a set of biologically relevant stimuli develops naturally after
early encounters
Following repeated exposure to these stimuli - habituation occurs
Adult phobias - childhood phobias have failed to habituate
The amygdala and fear
Two pathways that
detect danger and
trigger fear
responses
Fast, direct route -
Evolved fear module
(immediate)
Slower, indirect route
through cortical
processing areas
