Dr. Ted is using rats to assess the effectiveness of certain drugs on eating, body mass, and
activity. He gives either a low, medium, or high dose of drug A, B, or C to his test subjects. Each
rat is weighed daily, and the food it consumes is also recorded daily. A special laser grid (laser
beams intersecting every 5 cm) monitors each rat’s activity. That is, each time a laser beam is
broken the activity count goes up by one point. What is the independent variable?
a. body mass
b. activity
c. eating
d. none of the above

After you send your paper to a particular journal for review, the editor of the journal will, in turn,
send your paper to one or more experts in the area. These experts will carefully read your paper
for scientific merit and submit comments to the editor. This is termed:
a. the APA process.
b. peer review.
c. hell on earth.
d. the merit approval trial.

a. to generate new knowledge and to confirm that ‘truth’ is present
b. to organize and explain a variety of facts and to confirm that truth is present
c. to confirm that ‘truth’ is present and to disprove competing theories
d. to generate new knowledge and to organize and explain a variety of facts

Computers can present stimuli, such as words, “subliminally”—outside a person’s conscious
awareness—to study participants. Even though these words are presented too fast for the
participants to consciously read they still may be able to process or understand the words. Twentyfive participants subliminally received 20 God-related words (e.g., powerful and loving), and another
25 participants subliminally received 20 neutral words (e.g., pencil and building). After experiencing
the words, participants in both groups were asked to rate the extent to which natural disasters are
caused by God or natural factors.
You have completed your literature review and designed your experiment, and now you want to
begin to collect data. But before you do this you must first:
a. obtain a random sample of participants.
b. present your study to your peers at a brownbag luncheon.
c. determine the extent to which your findings may be due to chance.
d. evaluate the ethics of the research project.

After experiencing the words, participants in both groups were asked to rate the extent to which natural disasters are caused by God or natural factors. Which of the following statements is false regarding the psychological literature before beginning a research project? a. The process of conducting a literature search reminds researchers that science is a cumulative endeavour, with current research building on previous research. b. The process of conducting a literature search is much less tedious than it was 50 years ago. c. The process of conducting a literature search can provide a wealth of ideas for research projects. d. The process of conducting a literature search should be discouraged for a researcher who finds that another researcher has already investigated the same or similar research idea.

what are the major differences between non- experimental and experimental research methods?

In non-experimental studies it is difficult to determine the direction of cause-and-effect because temporal precedence has not been established. In other words, in non- experimental designs you simultaneously measure your variables; you don’t manipulate one and then see what happens to the other. For example, suppose you find an association between the consumption of ice-cream and number of shark attacks. Does eating more ice-cream, cause more shark attacks? Or does the increased number of shark attacks cause people to eat more ice-cream? Even though this example is called a spurious correlation, it illustrates that directionality cannot be determined in a non- experimental design. Another, more serious, problem with non-experimental designs is the third-variable problem. Often the relationship you observe in variables in non-experimental designs result because the variables in your study are both related to another variable that you have not measured (a third-variable). For example, in the ice-cream and shark attack example above, the observed relationship likely results because both shark attacks and ice-cream consumption are related to warmer weather. Thus cause-and-effect relationships cannot be made with non-experimental designs! We will talk about this at greater length in subsequent units. In the experimental method steps are taken to minimize the problems outlined above. First a control group is used and participants are randomly assigned to either this control group or an experimental group. This helps ensure that both the control and experimental groups are the same at the beginning of the study. During the study the experimental group is manipulated in some fashion. If at the end of the study the control and experimental groups are different on some measure, then the researcher can claim the experimental manipulation caused the change (or effect)

what are some advantages and disadvantages of the two basic research approaches?

Independent variables are manipulated or controlled by the experimenter. Dependent variables are measured by the experimenter. Dependent variables are thought to be influenced by the manipulation of the independent variables in a study
