Chapter 2: An Integrative Approach to Psychology (lecture) Flashcards
Model/Paradigm?
A set of assumptions and concepts that help us explain and interpret observations..ie perspectives
What are the four main theoretical perspectives?
Behavioural,
Biological,
Psychological
Cognitive
Biological Model (Bio-medical)
main focus is that psychological abnormality is an illness brought on by the malfunctioning of parts of the organism. (brain)
Bio explanation of abnormality?
Brain anatomy, Brain chemistry, Evolution and viral infections.
Brain Anatomy explanation?
problems in specific parts of the brain linked to psychological disorders.
ex: basal ganglia and huntington disease.
Brain Chemistry explanation?
Nt?
Endocrine?
abnormal activity with certain NT lead to specific disorders.
ex: depression: serotonin and norepinephrine
anxiety: GABA
abnormal activity in the endocrine system as well.
cortisol has been linked to anxiety and mood disorders.
Genetic explanation?
put you into a range for a risk towards certain disorders and than environmental stressors place you somewhere on that range.
ex: mood disorders, schizophrenia, mental retardation, alzheimers etc.
Evolution?
mutations inherited by ancestors in the family line.
understanding the evolution of abnormal behaviour.
Viral infection?
**in fetus.
provides abnormal brain structure or biochemical dysfunction.
ex: schizophrenia and prenatal viruses.
Bio Treatments?
3
- Drug therapy- restores biochemical balance. *most common
- electro convulsion therapy (ECT) - mood disorders
- Psychosurgery- last resort
Strengths of Bio Persp? 3
- considerable respect in field
- creates new therapies
- suggests new avenues of research
Weaknesses of Bio persp?4
can limit rather than enhance our understanding
too simplistic
evidence is incomplete or inconclusive
treatments produce significant amount of undesirable side effect.s
The Psychodynamic Model?
a persons behaviour is determined largely by underlying dynamic psychological forces which they are not aware of.
Psychodynamic Model’s take on cause of abnormality?
symptoms arise from the result of conflict among unseen forces.
Father of Psychodynamic approach?
Freud
Healthy person in relation to the id, ego and superego?
they have a compromise between the three forces.
Developmental Ego
each stage requires readjustment in the id, ego and superego.
successful=personal growth
unsuccessful= fixation @ early stage leading to abnormality.
parents are often blamed since they are key figures in early life.
Ego Theorists?(psychodynamic)
consider the role of the ego independent.
