General Cognitive Ability Task

Raven’s Advanced Progressive Matrices (RAPM) is used to measure high- level observation skills, thinking ability, intellectual efficiency, and intellectual capacity. This RAPM kit was purchased from the Western Psychology Society and it was developed by Pearson Education Inc. It is administered as per instructions provided with the kit by the publisher. The raw score of this test indicated the participants’ ability to make sense of complex situations. It consisted of 12 items for the practice session and 36 items for the test session and the recommended time duration was 30-40 minutes. Each item was a pattern with a missing element and four possible options. Only one option was the correct part of the pattern to be selected. A sample RAPM problem is provided in Fig. 7.3 (the correct answer in this case is 7). This task was performed by every participant of each group in the first session of the experiment. The raw score was used to control the nonexperimental variable “intelligence” in both groups.
