PSYA01H3 Lecture Notes - Lecture 7: Phonics, Operational Definition, Reading Education In The United States
Document Summary
* operational definition -> using a procedure or process to define something specific i. e. self-esteem manipulated to be when the experimenter drops the slides and yells at the participant and therein affects his/her self-esteem. To determine validity, you can do manipulation check. * asking participant at the end of the study, did you think that i blamed it all on you or not, and hopefully want the participant to blame themselves so the validity of the study increases. * other studies do similar experiments from the use of other operational definitions increases validity because if another experiment is proven valid, then this one can be proven valid as well. * reliability -> refers to how accurately the study can measure the dependent variable i. e. elastic band used to measure height not very reliable as there is a lot of variance in that. Can be measured and quantified -> when babies see colour, doing experiments on when they can see it.
