Q

psychological disorder

A

“clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or developmental processes underlying mental functioning. Mental disorders are usually associated with significant distress in social, occupational, or other important activities. An expectable or culturally approved response to a common stressor or loss, such as the death of a loved one, is not a psychological disorder. Socially deviant behavior (e.g., political, religious, or sexual) and conflicts that are primarily between the individual and society are not psychological disorders unless the deviance or conflict results from a dysfunction in the individual, as described above.”

Q

ADHD

A
  • disorder that involves impulsivity, hyperactivity (e.g., fidgeting, inability to sit still), and difficulty shifting attentional focus
  • Is there too much emphasis on individual interventions instead of structural societal changes?§More opportunities for play, accommodation for range of temperaments & behaviours
  • Why does it matter?
  • Labels carry stigma, can contribute to social exclusion, stereotyping, discrimination, shift in self-concept & potential for self-fulfilling prophecies
  • Once a label is applied, all subsequent behaviour is interpreted through that lens
  • Pharmacological treatments may pose risk of side-effects
  • ADHD treated with stimulant methylphenidate, which can be addictive and pose long-term side effects

Q

clinical assessment

A
  • procedure for gathering the information to evaluate an individual’s psychological functioning and to determine whether a clinical diagnosis is warranted
  • clinical interview: interview in which a clinician asks the patient to describe his or her problems and concerns
  • Self-report measures: standardized clinical assessment consisting of fixed set of questions that a patient answers
  • projective tests: A form of clinical assessment in which a person responds to unstructured or ambiguous stimuli; it is thought that responses reveal unconscious wishes and conflicts

Q

major depressive disorder

A
  • mood disorder characterized by prolonged feelings of sadness, worthlessness, emptiness, and anhedonia

Cognitive factors:
- Rumination= continuously focusing on emotional pain without active problem-solving
- Explanatory style= cognitive style that determines how individuals explain adverse events
- Internal:blaming oneself (“it’s my fault”)
- Global: generalizing problem to all aspects of life (“everything is ruined”)
- Stable: believing problem is unchangeable (“it will always be like this”)
- Social & environmental factors:
- Stressful experiences interact with individual predisposition factors (diathesis-stress model)
- Biological factors:
- Serotonin long-considered key player in mood regulation, but precise role is debated
- Selective serotonin reuptake inhibitors (SSRIs) effective for treating depression(effective for anxiety as well)
- BUT: delayed effects—what is the mechanism?
- Cortisol-induced inhibition of growth processes, brain shrinkage
- Reward deficit—dopamine, opioids
-Some antidepressants target dopamine neurotransmission
- Heighted inflammation

Q

bipolar disorder

A
  • mood-related disorder characterized by both manic (excited and energetic) episodes and depressive episodes
18
Q

schizophrenia

A
  • psychological disorder characterized by a loss of contact with reality and pronounced disturbance in thinking, perceptions, emotion, and action
  • Enlarged ventricles due to reduced brain volume
  • Reduced volume especially in frontal and temporal lobes
  • Loss of gray matter in prefrontal regions that support working memory
  • Some brain differences may precede schizophrenia, serving as a diathesis
  • genetics: Concordance rates are three times higher for monozygotic twins than dizygotic twins
  • Determining which genes are involved has been difficult and nonconclusive
19
Q

positive and negative symptoms of schizophrenia

A
  • positive: behaviours that are not present in healthy people
  • negative: absence of behaviors usually seen in healthy people
20
Q

hallucinations vs delusions

A
  • hull: sensory experiences, such as sights and sounds, that happen in the absence of any true sensory input
  • delulu: false, unrealistic beliefs that are rigidly maintained despite overwhelming contradictory evidence
21
Q

dopamine hypothesis of schizophrenia

A
  • schizophrenia arises from an abnormally high level of activity in brain circuits that are sensitive to the neurotransmitter dopamine
  • Supporting evidence:
  • Amphetamines (which promote dopamine neurotransmission) may provoke schizophrenic symptoms
  • Typical antipsychotics(which block dopamine neurotransmission) alleviate positive symptoms(but not negative symptoms)
  • More recent research has shown that general dopamine excess is not the sole cause of schizophrenia, but that dopamine imbalance is involved
  • Other neurotransmitters play role—e.g., newer antipsychotic medications target serotonin as well
22
Q

personality disorders

A
  • Personality disorders are a class of mental health conditions characterized by enduring maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by the culture
23
Q

24
Q

dissociative identity disorder

A
  • psychological disorder characterized by presence of multiple distinct personality states within the same person
25
Q

psychoanalytic elements of free association, resistance, interpretation, and transference

A
  • psychoanalysis: method of therapy, developed by Sigmund Freud, for uncovering unconscious conflicts, often rooted in childhood, that contribute to clinical symptoms
  • free association: saying whatever comes to mind
  • resistance: avoiding certain ideas
  • interpretation: explaining how certain thoughts and feelings arise
  • interpretation: explaining how certain thoughts and feelings arise
  • analysis of transference: clients’ tendencies to respond to the analyst in ways that recreate their responses to the major figures in their life
26
Q

modern psychodynamic therapy vs Freud

A

Scope:
- Psychoanalysis: strong emphasis on the unconscious mind, focusing on deep-rooted repressed conflicts, often rooted in childhood
- Psychodynamic approach: Considers the unconscious important but gives more weight to conscious thoughts and emotions; emphasizes current relationships, self-concept, and coping with present challenges
- Approach:
- Psychoanalysis: intensive, long-term
- Psychodynamic approach: less intensive, more time limited

27
Q

humanistic approach to therapy

A
  • Emphasis on people’s inherent potential for self-fulfillment & personal growth
  • Regarded psychoanalysis and psychodynamic approaches as too concerned with basic urges, tension reduction, and the past oInstead, focused on the search for meaning, self-actualization in the here-and-now
  • Client-centered therapy= the therapist’s genuineness, unconditional positive regard, and empathic understanding are crucial to therapeutic success
  • Seeks to help clients bridge the gap between their self-concept and ideal self by accepting themselves as they are
28
Q

classical and operant conditioning - behavioral therapists

A

Classical conditioning involves forming associations between stimuli to influence behavior. Therapists often work to break maladaptive associations or form positive ones.

Operant conditioning involves using consequences (rewards or punishments) to increase or decrease the likelihood of a behavior.

29
Q

exposure therapy

A

Behavioural techniques designed to remove the anxiety connected to a feared stimulus through repeated exposure

30
Q

systematic desensitization

  • Reinforcement can be gradually adjusted (shaping)
32
Q

modeling

A

Behaviouraltherapy technique based on observational learning,in which patients learn new skills or change their behavior by watching and imitating another person (e.g., the therapist)

  • Emphasizes that they can commit to pursuing valued goals despite unwanted thoughts and feelings
38
Q

limitations to evaluating the effectiveness of therapies

A
  • Potential differences in people who responded to the survey and those who did not
  • People may feel the need to justify spending their time and money on therapy by reporting benefits (what does this remind you of?)
39
Q

regression to the mean

A
  • Extreme scores tend to move closer to the mean over time
  • Complicates interpretation of changes in clients’ symptoms
40
Q

common factors thought to underlie therapy effectiveness

A
  • The apparently comparable effects of different forms of therapy may be explained by the common factors they share:
  • Establishing a strong relationship with the patient (therapeutic alliance)
  • Offering new ways of thinking
  • Instilling hope
41
Q

therapeutic alliance

A
  • the bond (rapport) between client and therapist, characterized by emotional connection, trust, collaborative approach
  • May be the most important ingredient in effective psychotherapy, even when medication is the primary treatment
