Ch. 7word count required: 300 wordsan experimenter examined the effects of lsd on complex learning in rats. one group of rats was given a very small dose of lsd--so small that it was unlikely to have any behavioral effects. a second group was given a large dose. then both groups ran through a complex maze several times. the dependent variable was the number of errors the rats made before obtaining the food reward at the end of the maze. the large-dose group made 4.5 times as many errors as the small-dose group, and the experimenter concluded that lsd can negatively affect complex learning. comment on the levels of the independent variable that were used. what other dependent variables could be recorded? comment on the conclusion by the experimenter.
