PSYB32H3 Chapter Notes - Chapter 1: Little Albert Experiment, Prefrontal Cortex, Deep Brain Stimulation
Document Summary
Psycho-stimulants add, dementia, creates alertness [teens use this a lot: amphetamines. Ritalin; aricept: adhd patients: found reduction in volume throughout cerebrum and cerebellum. Experience delays in cortical maturation, which most evident in lateral prefrontal cortex. Lateral prefrontal cortex: region responsible for working memory and attention. Dopamine hypothesis: believed adhd is due to dopamine deficit due to genetic: abnormality in reward-related circuitry = shorten delay gradients, deficit in temporal processing that result in high intrasubject intertrial variability, deficits in working memory. Stimulants: used to treat attention deficit hyperactivity disorder. Deep brain stimulation: procedure used to treat various chronic mental health and health conditions. Involves planting battery-operated electrodes in brain, which deliver low-level electrical impulses: used to treat alleviate treatment-resistant depression patients. Behaviourism: arised by john b. watson switches the focus from thinking to learning in psychology. Behavioural paradigm: orientation that based on the notion that abnormal behaviour is acquired: behaviour is acquired based on behaviour receive reinforcement or punishment.
