PSYB01H3 Lecture Notes - Cortisol, Inter-Rater Reliability, External Validity
Document Summary
Definition: something that varies; can take on diff values feature of an object that can have more than 1 value (psych: it"s going to be person/animal mostly) Examples: level of creativity, # of siblings, color food, height, weight. Purpose of psych research: simplify the complex by exploring key variables that can explain differences in behaviour; which variable is responsible for the way an organism responds in particular situation. Slide 3: variability in behaviour: differences in the way ppl (or other organisms) respond to the same stimulus. Why is it/what are the things that create the differences in the way ppl react: types: Variable that we"ve been able to explain. Unexplained variation: ex) mouse runs thru the classroom. Ppl may react differently; why ppl react in diff ways; help predict beh; why diff kinds of beh exists; why the variation. Still some variation in responses left between people.
