A different example of Instrumentation Effect that leads to a threat to the internal validity in an experimental study is as follows.

Imagine a study where the researcher uses toys to measure the amount of play a female child has with them based on their appearance.  If the researcher originally uses toys that are gender neutral in the pretest and uses different toys that are more female directed in the posttest there will be an increase in the amount of play by the participants.  The changing of the toy from pretest to posttest is the instrumentation effect that leads to a threat to the internal validity in this experimental study.
