It is based on: Montross, J.F., Neas, F., Smith, C.L., and Hensley, J.H. (1988). The effect of role-playing high gender identification on the California Psychological Inventory. Journal of Clinical Psychology, 44: 160-164.
Clinical psychologists have developed several ways to assess an individual's personality traits from answers given to a series of carefully selected questions. One such instrument is the California Psychological Inventory, which consists of 15 scales designed to give insight into some facet of a respondent's behavior and personality and 3 additional validity scales designed to detect individuals trying to fake certain personality traits. Even though these validity scales are present, Montross and his coworkers wondered if the overall assessment of personality with this instrument could be affected by faking strong gender identification - men responding in a very "macho" manner and women responding in a very "feminine" manner - without being detected by the validity scales.
To evaluate the effect of faking strong gender identification, they administered the California Psychological Inventory to 16 men and 16 women. Half of each sex were given standard instructions, whereas the other half were instructed to role-play so that they answered the questions in the way they thought an extremely masculine man (male subjects) or extremely feminine woman (female subjects) would answer. The data for 1 of the 15 personality assessment scales, the Sp scale, appears below.

The tensile strength (in pounds per square inch) of various types of asphaltic concrete is being investigated. There are two aggregate types (the material it is made of) and four compaction types (how it is prepared). One of the compaction types is to just leave it static, the other three are levels of kneading. It is thought that Basalt aggregate makes a stronger concrete than the Silicious aggregate. It is thought that there may be a difference in the effect of switching from Basalt to Silicious when the compaction method is Static vs. when the compaction method is one of the Kneading methods. Finally, it is desired to determine what the most effective method is when the Regular Kneading is not an option.
