Document Summary

Psychology 1000 - lecture 3 - the science of: definition of, methods in, descriptive, experimental, characteristics, variables, drawbacks. Can also be done outside of the lab in field experiments. Experimental method is a matter of logic not location. Primary characteristic is control over the conditions/factors that rise to the behaviors of interest. (rats raised in dark vs. in visually enriched environment to learn visual discrimination) Rat is placed on platform that can fling rat onto next platform with two blocks, one with triangle picture on left and circle picture on right, the pit contains cats. the picture with circle contains rat food behind it. Hypothesis: rat raised in dark would have more difficulty distinguishing which cube contains rat food. Therefore hypothesis would be rats raised in visually enriched environment would have less difficulty distinguishing between both cubes. To correct this: change the positions of the pictures so that the circle is on the left and triangle is now on the right.
