Primary use / Purpose: 

The PPQ presents respondents with images of physical systems, and asks them to predict outcomes of specific motions. There are 40 items, each with 5 possible answers.


The Physical Prediction Questionnaire (PPQ) was developed to test the Empathising-Systemising theory of gender differences, as well as the Extreme Male Brain Theory of autism. According to these theories males and those with Aspergers syndrome or high-functioning autism should perform best here.
