A correlation is: - a number between -1 and +1 that describes the strength and direction of a relationship between two variables. It has two parts, a sign (+ or -) and a number. a correlation of 0 means - no relationship A hypothesis is- - A hypothesis is a testable prediction about the relationship between one or more independent variables and a dependent variable derived from a theory. Alcohol - Affects many different neurotransmitters, including GABA, norepenephrine, dopamine, and acetylcholine. Some are produced more but some less, Also produces endorphins Applied Psychologist - Corporations, hospitals, clinics, Practical problem solving, Provide services to the public behavioral - emphasizes the conditioning of our behavior biological - how our physiological (brain and nervous system) produces our behavior Brodmann's Map - Studied "cytoarchitecture" That's psychologist-speak for "types of cells and their arrangement", he assigned numbers to each similar-seeming region case study - a researcher researches an individual in depth over a long period of time Cocaine - blocks reuptake of dopamine and norepinephrine, leading to overabundance cognitive - how mental processes such as perception and memory workCT Scan - Pronounced "Cat" scan•Uses x-rays, Not very detailed, Good for spotting major damage Difference between central nervous system and peripheral nervous system - CNS is made up of the brain and spinal cord, the PNS is the part of the nervous system that links the CNS with the body's receptors, muscles, and glands Electrochemical process: - Both electrical - the action potential (in the cell) and chemical - neurotransmitters (between cells) ERP/EEG - Reads electrical impulses through the skull, Good temporal resolution (know WHEN things happened), Bad spatial resolution (don't know WHERE) Experimental Psychologist: - Usually work at universities, Some at hospitals/clinics, Produce research on behavior fMRI- - Functional Magnetic Resonance Imaging Uses big magnets, Detects oxygen in blood, As more blood comes to an area, more oxygen comes with it, Great spatial resolution, poor temporal resolution Four Major Research perspectives - Behavioral, sociocultural, cognitive, and biological perspectives Glial cells - provide structure and nutrition hindsight bias - the tendency- after learning about an outcome, to be overconfident in ones ability to have ''predicted'' it.
