After detailed study of a gunshot wound victim, a psychologist concludes that the brain region destroyed is likely to be important for memory functions. Which research strategy did the psychologist use to deduce this?
In an experiment to determine the effects of exercise on motivation, exercise is the:
In order to deterine the effects of a new drug on memory, one group of subjects is given a pill that contains the drug. A second group is given a sugar pill that does not contain the drug. This second group constitutes the:

The scientific attitude of skepticism is based on the belief that:

random sample; population
Well-done surveys measure attitudes in a representative subset, or _____, of an entire group, or _____ .
all of the above
In generalizing from a sample to the population, it is important that: (a. sample is representative of population; b. sample is large; c. scores in sample have low variability; d. all of the above)
the difference is not likely to be due to chance variation.
When a difference between two groups is "statistically significant," this means that:

Have the American Psychological Association and the British Psychological Society have set strict guidelines for the care and treatment of human and animal subjects?
Have the allegations that psychologists rountinely subject animals to pain, starvation, and other inhumane coditions have been proven untrue?
overestimate the extent to which others share our belief.
One reason researchers base their findings on representative samples is to avoid the false consensus effect, which refers to our tendency to:
The procedure designed to ensure that the experimental and control groups do not differ in any way that might affect the experiment's results is called
