Question

47 Three groups of I/O psychology students are learning about "goal setting theory." The first group page description of the theory, the second group hears a lecture about the theory, and reads a one- the third group observes a demonstration of the theory. All three groups are tested on their understanding of the theory, and their exam scores are compared. Identify the type of research design used (laboratory, quasi-, or non-experiment), the independent/predictor variable, the dependent/criterion variable, and the measures or manipulations used where appropriate. Also, describe why you chose your answers (i.e., why is the study characteristic of the design chosen, why is it a predictor or IV, etc.).

Explanation / Answer

Answer 1.

The given study is based on the experimental design as the independent variable is manipulated by the researcher to study its effect on the sample of three groups under controlled testing conditions. Here, the sample is divided into three groups each of which is introduced to a different learning approach- my reading a text, by verbal lecture and by observational learning. The three groups are then compared in terms of their performance on a test of knowledge about ‘goal setting theory’. In the study, the researcher is likely trying to draw a causal relationship between the teaching method and the student’s performance and hence he incorporated the experimental design in the study. Here, the type of method to introduce the topic is the independent variable which is manipulated by the researcher across the three sample groups and the dependent variable is their test scores.
