breaks down and cannot perform its normal function
4
Q
- Significant disturbances in thoughts, feelings, and behaviours.
- Outside of cultural norms.
- The disturbances reflect some kind of biological, psychological, or developmental dysfunction.
- The disturbances lead to significant distress or disability in one’s life.
- E.g. difficulty performing appropriate and expected roles.
A
American Psychological Association (APA) Definition of a Psychological Disorder

Diathesis-Stress Model
14
Q
Diathesis + Stress → Development of a disorder

others to develop a disorder when faced with adverse environmental or psychological
events. - A diathesis can be a biological or psychological vulnerability.

which of the following theories surrounding panic attacks is this referring to?
Panic attacks are responses to subtle bodily sensations resembling those normally occurring when one is anxious or frightened
conditoning theory
33
which of the following theories surrounding panic attacks is this referring to?
individuals with panic disorder are prone to interpret ordinary bodily sensations catastrophically, setting the state for panic attacks.
* In some patients, reducing catastrophic cognitions about sensations has proven
to be as effective as medication in reducing panic attacks
cognitive theory

name the main theory behind generalized anxiety disorder:
cognitive theory
- Worry represents a mental strategy to avoid more powerful negative emotions perhaps stemming from earlier unpleasant or traumatic experiences.

conditioning theory
53
which of the following theories surrounding PTSD is this referring to?
2 main ideas behind this theory
- Disturbances in memory for the event.
- Individuals cannot remember event in a way that gives meaning and context.
- May become haunted by these fragments involuntarily triggered by stimuli associated with the event.
- Negative appraisals of the trauma and its aftermath (e.g., ”I deserve to be raped because I am stupid”).
- May lead to dysfunctional behavioral patterns that maintain symptoms and prevent changes in the problematic appraisals
cognitive theory
54

depressive disorder
55

name the 4 main theories/reasons behind why people have mood disorders
- genetics
- hormones
- neurotransmitters
- brain anatomy
67
how are genetics related to mood disorders?
relatives have double the risk -specifically with bipolar disorder
68
how are hormones related to mood disorders?
* Elevated levels of cortisol (stress hormone) are found in depression.
* Cause or consequence of depression?
* A risk factor for future depression.
* Cortisol activates the amygdala and deactivates the prefrontal cortex (disturbances connected to depression).
69
how are neurotransmitters related to mood disorders?
- Mood disorders often involve
imbalances in neurotransmitters.
* Particularly serotonin and
norepinephrine.
These neurotransmitters are involved in bodily functions that are disrupted in mood disorders.
Many medications designed to treat
mood disorders work by altering
neurotransmitter activity in the neural
synapse.
Medications for depression – usually
increase serotonin and norepinephrine
activity.
Medication for bipolar – Lithium, which
blocks norepinephrine activity at the
synapse.
70
how is brain anatomy related to mood disorders?
Amygdala – important in assessing the emotional significance of stimuli and
experiencing emotions.
* Depressed individuals react to negative emotional stimuli, such as sad faces,with greater amygdala activation than do non-depressed individuals.
* More prone to react emotionally to negative stimuli.
Prefrontal cortex – important in
regulating and controlling emotions.
* Decreased activation in
depressed individuals which
may inhibit its ability to
override negative emotions.
* Greater difficulty controlling
emotional reactions.
71
what equation is this referring to
cognitive vulnerability + stressful life events → depression
Diathesis-Stress model
72
what equation is this referring to
1 or 2 short alleles + stressful life events → increasingly likely to experience a depressive episode
genetic vunerability
73
aaron becks theory that depression-prone people possess mental predispositions to think about
most things in a negative way (depressive schemas)
depressive schemas
- contain themes of loss, failure, rejection, worthlessness, and
inadequacy
74
what are the 2 cognitive theories behind depression?
- hopelessness theory
- rumination
75
what cognitive depression theory is this referring to?
Negative thinking – refers to a tendency to perceive negative life events as having stable (”It’s never going to change”) and global (“It’s going to affect my whole life”) causes.
* Creates view that the life event will have negative implications for the person’sfuture and self-worth, increasing likelihood of hopelessness.
Hopelessness - expectation that unpleasant outcomes will occur or desired outcomes will not occur, and there is nothing one can do to prevent such outcomes (seen as the primary cause of depression).
hopelessness theory
76
what cognitive depression theory is this referring to?
repetitive and passive focus on the fact that one is depressed and dwelling on depressed symptoms, rather than distracting one’s self from the symptoms or attempting to address them in an active, problem-solving manner.
rumination
Distressed mood → rumination → increased risk and duration of mood
77

schizophrenia
84
4 reasons for schizophrenia :
- genetics
- neurotransmitters
- brain anatomy
- events during pregnancy
85
how are genetics related to schizophrenia ?
Risk is 6 times greater if one parent has schizophrenia (even if adopted)
86
how are neurotransmitters related to schizophrenia ?
Dopamine hypothesis – an overabundance of dopamine or too many dopamine receptors are responsible for the onset and maintenance of schizophrenia.
* Drugs that increase dopamine levels can produce schizophrenia-like symptoms.
* Medications that block dopamine activity reduce the symptoms.
* High levels of dopamine in the limbic system → hallucinations and delusions.
* Low levels of dopamine in the prefrontal cortex → negative symptoms.
87
how is brain anatomy related to schizophrenia ?
* Enlarged ventricles.
* Reduced gray matter in the frontal lobes.

be it individuals, inanimate objects, or all surroundings” (APA, 2013)
derealization
95
- Individual exhibits
two or more separate personalities or identities.
* Involves memory gaps for the time during which another identity is in charge.
* Individuals tend to report a history of childhood trauma - Adoption of multiple personalities may serve as a psychologically important coping mechanism for threat and danger.
