Document Summary
This causes the atoms to start spinning and, if they are the same density, will all stop at the same time: pet scan is a sort of metabolic imaging of the brain, ie. how the brain uses glucose. Also radioactive and thus not used on children. Difficult to get absolute correlations but 0. 8 or 0. 9 is very high. If no correlation, there may still be a relation, just not a linear relation: cannot find definite causality chick or egg, unknown variable, etc, depends on strength and direction. How does the child react to separation and reunion: randomised control trials: studying effectiveness of treatments. Placebo effect: a substance that looks like a drug but is actually inactive. Double-blind: both participant and experimenter are unaware which treatment being administered. Assistant research will encode results through documentation: single-case experiment, behaviour of 1 person before and after iv, abab, ex. Baseline measure = a (starting point), ie. how often child smiles per minute.
