Sept 20, 2011 Psych Research in psychology Three types of scientific research Naturalistic observations Includes: case studies (individuals) Correlation studies (observation and measurement without manipulation)— questionnaires to collect data (like last class with the satisfaction of life/perceived stress). Can’t many inferences about causation. Have to keep everything else controlled (temp, noise, etc) so it’s consistent between participants. Ex. Will mood have effect on environmental altruism (ex good feelings towards the environment). Then show puppies and kittens to up the mood, then see if environ. Altruism went up for another group.
