Phobias Flashcards
stress
a state of psychological and physiological arousal produced by internal or external stressors that are perceived by individuals as a challenge or exceeding their ability to cope
anxiety
a state of physiological arousal associated with feelings of apprehension, worry or uneasiness that something is wrong or unpleasant is about to happen
anxiety disorder
a group of mental disorders that are characterised by chronic feelings of anxiety, distress, nervousness and apprehension about the future with a negative effect
(specific) phobia
characterised by an excessive or unreasonable fear of a particular object or situation
- out of proportion
- produce a desire to avoid the stimulus
- thoughts alone can lead to a phobic reaction
- diagnosable
specific phobias
- animals
- situational
- natural environments
- blood/injection/injury
- other phobias
panic attacks
a period of sudden onset of intense fear or terror, often associated with feelings of impending doom
anticipatory anxiety
a gradual rise in anxiety level as a person anticipates being exposed to a phobic stimulus in the future
GABA dysfunction
- precipitating
- without GABA, activation of the postsynaptic neuron might get out of control
- might cause anxiety and FFF responses
the role of the stress response
- precipitating
- the perceived stressor, whether dangerous or not, elicits the FFF response
- the response can become associated with the phobic stimulus through CC
long-term potentiation (bio factors of phobia)
-plays an important role in learning and memory of fear by strengthening synaptic connections in the neural pathway formed during the learning process
classical conditioning (psych factors of phobia)
precipitating
operant conditioning (psych factors of phobia)
- perpetuating
- after acquisition through CC, a person may avoid the phobic stimulus
- leads to negative reinforcement (–)
cognitive models (perpetuating)
emphasise how and why people with a phobia have an unreasonable and excessive fear of a phobic stimulus
cognitive bias
a tendency to think in a way that involves errors of judgement and faulty decision making
memory bias
the distorting of influences of present knowledge, beliefs and feelings as the recollection of previous experiences
selective memory
the tendency for memory recall of a phobic stimulus to be better for negative or threatening information than positive or neutral information
catastrophic thinking
overestimating, exaggerating or magnifying an object or situation and predicting the worst possible outcomes
specific environmental triggers
- precipitating
- specific objects or situations in the environment that triggers an extreme response
stigma around seeking treatment
- perpetuating
- sufferers of phobias are likely to suffer from stigma and avoid telling other of their fear
