The simple experimental study forms an important part of psychological training. It enables students to demonstrate the application of their skills and knowledge of psychology. The psychology course defines the experimental method as requiring the manipulation of one independent variable, while other variables are kept constant. Consequently, correlational studies, quasi-experiments and natural experiments (that is, any research undertaken without control over the independent variable and without a controlled sampling procedure), including the use of gender or age as the independent variable, are not acceptable for the simple experimental study.
SL students are required to undertake a partial replication of a simple experiment. Examples of experiments that may be replicated and that may be made applicable at the standard level and include (for our course) some topic related to the cognitive perspective, which include, but are by no means limited to: memory, attention, or perception.
1. Undertake a partial replication of and report on one simple experiment
2. Present results systematically
3. Use descriptive statistics only (see intro to research methodology)
4. Produce a written report between 1000-1500 words that must consist of
a. Title page
d. Method: design, participants, materials, procedures and ethics
