PSYA01H3 Lecture Notes - Lecture 6: Dependent And Independent Variables, Phonics, Random Assignment
Document Summary
Lecture 6: experimentation- finding the cause & ethics and research marketing. Experiment is needed to establish a causal relationship. Vs humans diving to swim with sharks, sharks do not want to eat humans (fussy eaters, only want to eat fish) The cage is the reason for sharks attacking, sharks can sense electrical signals on their snout to hunt and the metal conducts electrical signals causing sharks to falsely sense it and attack the cage, not the human. Hypothesis: the shark wants to attack the metal cage due to electrical signals causes aggression in the shark. A possible experiment: a shark in water, then to put the metal rod into the water, that can conduct currents of electricity (can be turned on/off), see if shark will attack. E. g. need to measure aggression in sharks, can"t be abstract. To measure aggression, shark bite/bumping bar (how many times)
