PSY 102 Lecture Notes - Lecture 2: Frontal Lobe, Lobotomy, Scientific Method
Document Summary
Prefrontal lobotomy: used to treat schizophrenia and other severe mental disorders, severed the fibers connecting the frontal lobe and thalamus, controlled studies show it does not work, no regulations at the time it was being done. Hm removal of temporal lobes to cure seizure activity. The scientific toolbox: naturalistic observation, watching behavior in real-world settings (both humans and non-humans, high external validity - findings are generalizable to the real world, low internal validity - ability to draw cause-and-effect inference, descriptive research. Concerns: reactivity: did individuals change their normal behaviour because they were being observed, e. g. child becomes more/less aggressive, case study. Studying one or a small number of people for an extended period of time. Types of reliability: test-retest reliability similar scores over time, interrater reliability two raters should produce similar scores (e. g. if two doctors came, the patient would likely tell the doctor similar symptoms they"re feeling) + direct (self) assessment of a person"s state.
