Document Summary

Psychology a01: lecture 2. 1: finding answers begins by finding questions. Begins with a theory somebody"s explanation meant to explain things they have seen. Good theories lead to hypotheses predictions that can be empirically teste in a way that might prove them to be incorrect (i. e. falsifiable) Freud"s theories of human behaviour, and religious theories of existence are often criticized for being unfalsifiable and therefore impossible to test. Observational study jane goodall lived with chimps. Her goal to see natural chimp behaviour. Subordinate chimp doesn"t look at the superior chimp in the eye unless they imply a challenge/fight. Terminology: variable refer to anything that can take on multiple values: eye colour values of green, blue, brown, etc. It is a categorical variable: height- a continuous variable because it values lie on a continuum. Whether a variable is categorical or continuous often depends on how it is measured.
