Document Summary

Psyc100 lecture 7 (tuesday, 25 september 2018) Continuation from last lecture : empirical structuralism: Inferential stats helps with this: ex: texting on phone decreases loneliness (hypothesis) Null hypothesis (h0), experimental hypothesis(h1) (alternative hypothesis) T-test used if passed, means there is a statistical significant difference. Values under h0 and h1 distribute in certain way. P = 0. 05- probability that difference between the treatment is due to chance. Type i error: falsely reject the null hypothesis (h0) Type ii error: falsely reject experimental hypothesis ( h1) Actual lecture: genes and behaviour: nature vs nurture nativism vs empiricism (refer to psyc301) Nativism (nature) knowledge of world is innate and determines abilities (descartes dualism; mind and body are separate entities) Empiricism (nurture) behaviour is acquired through experience and therefore can be modified (john locke new born baby mind is blank slate; tabula rasa) To answer which approach i right or not, must look back on human evolution.
