This component contains all stimuli necessary for administration of the Army Beta to college students. The files are:
- Army Beta Scoring Instructions: This is a PDF file of an excerpt from Yerkes (1921) in which he explains how to score the Army Beta.
- Army Beta test key: This PDF file is the test key for the Army Beta, based on the instructions given in the previous file. Note that item 8 on Test 6 (the picture completion test) is incorrect. The stamp should be in the upper right corner of the envelope. [The grading error for this item was corrected when the research team checked the data for accuracy][1].
- Army Beta test only: This PDF file contains just the Army Beta stimuli. Individuals who wish to administer the Army Beta may find this file convenient because it does not contain the informed consent or demographic survey that the "Stimuli" file contains.
- Beta instructions: This is a PDF file that gives the test administration instructions that were used to create the administration video at https://www.youtube.com/watch?v=HAMQPJyUiuo.
- Demographic survey: This Microsoft Word file contains a 5-question demographic survey that asks participants their sex, racial/ethnic heritage, college admissions test scores, and current overall college GPA.
- Stimuli: This PDF file is a packet that each participant received in order to take the Army Beta. The packet consists of the informed consent document, the Army Beta stimuli, and the demographic survey. Printing this document two-sided (including blank pages) will ensure that video instructions match what examinees experience.
Note: There are two slight differences between the video and the actual Army Beta administration. First, on Test 2, the real Army Beta instructors had a small model of the blocks that they showed examinees to help them understand that the picture represented a three-dimensional object. Second, on Test 7 the WWI examiners demonstrated the first three example problems with paper cutouts. In the video, we only used paper cutouts for the first example problem.
