31
Q

What is the Neurobiological model of OCD? (Frontal lobe and basal ganglia)

A

Interactions between frontal lobe and basal ganglia-there is an overactivity in connection (initiation of behaviour). Frontal lobes sare then unable to take control of obsessions, flow to basal ganglia, reaction.

32
Q

What is theN Neurobiological model of OCD (memory problems and confidence)

A

Lose confidence in memory, compensate with obsessions to help with it

33
Q

What is the Neurobiological model of OCD (serotonin hypothesis)?

A

Drop in serotonin in parts of the brain having to do with fear and anxiety (evidence for this is not great)

Classical conditioning of thinhs like fear and disgust (explains animal and germ phobias). More disgust=more anxiety. Mitigated by biological preparedness.

56
Q

A

Certain situations we fear because we should fear them-evolutionary based

57

Emotions like fear are classically conditioned, but maintenance- occurs with operant conditioning- specifically with avoidance (we get rewarded for avoiding things).

62
Q

A

When you believe that thinking something is equivalent to doing (ex: thinking violent thoughts is the same as committing violent acts)

63
Q

What is dual representation theory?

A

Traumatic memories are encoded in images (not complete). When people cannot put into words what they saw, they become distressed.

A

Tendency to overgeneralize threats-fear stays with you even if it is not too traumatic. Person generalizes event to fear of the world

65
Q

What are some biological factors in anxiety disorders?

A 
Genetic
Biological preparedness (phobias)
Neurological factors (Brain structures)
Neurochemistry
66
Q

What is the fear circuit?

A

Incredibly primitive part of brain that only uses the sensory part of cortex and middle structures (thalamus, amygdala). PFC has the role of interpretation and managing fear requires the neocortex
