 Maier’s Two String Experiment: Facilitatory effect of set

Maier’s ‘Two string Problem’ consists of two strings hanging from the roof in such a way that holding one string & the subject cannot reach the other. The subject is required to figure out a way to lie two strings together, even though when he is holding onto one string, the other is out of reach. A variety of objects are available for use in the solution of the problem, such as air, tissue paper, a pair of pliers & some paper clips.

The solution involves trying the pliers to the string & setting it in motion like a Pendulum so that it can be reached while the subject is holding onto other string. Maier presented this problem to two group of subjects. One group of subjects (experimental. group) were shown a string moving like a pendulum before the problem was given. The other group (i.e control group) were not given any such experience. The performance of the experimental group was better than the control group.
