Dr. Park identified 20 restrictive eaters (people who constantly monitor and limit their caloric intake) and 20 matched control participants. She then manipulated whether each group of participants had or had not just consumed a high calorie milkshake prior to taking part in a "taste test" of chocolate chip cookies.

a person-by-treatment quasi-experiment

Explanation:

Quasi-experimental design: In a psychological experiment, the quasi-experimental design is designed to select groups on which a variable is being tested, in the absence of random selection.

Example: In a quasi-experimental design, a researcher while experimenting divides the population based on age, similar age group participants would be placed in the same group.

Person-by-treatment: The person-by-treatment design is one of the common types of quasi-experimental design. In person-by-treatment, a researcher tries to measure at least one of the independent variables, and side-by-side manipulate the other independent variable.
