Lecture 3 - readings BEFORE lecture (experimental design should be done for today) - best way to learn is in little bits and pieces every day so your brain can assimilate the information - when we discussed ethics at the end of the last class; really there are so many more ethical concerns - the bulk of what we learn will be from the book - an ethical consideration with humans, the participants have a right to privacy and the right to drop out at any point (there should be no news report about you and your funny brain and your name should be kept separate from the data) - we believe you are more likely to get better data from somebody when they feel comfortable being themselves, etc - science progresses in stages (all empirical sciences, physics, chem, bio) - ±rst goal is a description of behavior - we psychologist often engage in descriptive studies to describe the nature of a situation (just to describe what we have, not necessarily due to a hypotheses, just to collect a phenomenon) - prediction: eventually you want to be able to predict behaviour (by ±rst observing) - often psychologists just observe behaviours in a classroom in order to understand what’s going on and build a hypotheses about what kind of data they might need to collect - summer camp with kids with Williamsville disease - they were watched for a week straight just to see what their behaviour was like and only after that we did tests on intelligence, etc - there was not much known about their disease and what effects it had on them so we just observed them for a week because we didnt know enough to know which questions to ask - the cautious scientist must soak in the information before jumping into testing - only after observations we can predict future behaviour - after predictions the next goal is to determine causes of that behaviour 1. description of behaviour 2. prediction of behaviour 3. determination of causes of behaviour 4. explanation of behaviour - goal of psychology is to explain behaviour - at ±rst early humans that looked up at the night sky were able to describe the positions and motions of stars in the planets - our early ancestors thought the earth was at the centre but were able to track the movement (but no ability to predict where a given body would appear in the sky at a future date) - but they were able to describe them, and they gave these things names Sept. 9th, 2010

- then with systematic documentation, early philosophers could predict the motion - it took centuries until they could come up with an account of what caused the motion - it was the discovery of gravity and laws of motion and relativity that gave us an understanding of the causes of the orbits and
