Solso and mccarthy (1981) asked subjects to remember a set of faces created using police identikits. subjects were later tested on some of these studied faces as well as some new faces, including one composed by averaging all the studied faces. the critical finding was that

Solso and McCarthy did the prototype effect experiment (1981) combining hair, eyes, nose + chin, and mouth and produced few examples variating some of those components. Prototype effect is a tendency to recognize the face by corresponding to the central value of a series of seen faces, even when this central value (prototype) has not been seen. The critical finding was that subjects confidently misidentified the prototype face with formerly seen face. The results were the same in second experiment as well.

the united states constitution is the supreme law of the united states. the constitution, originally comprising seven articles, delineates the national frame of government. its first three articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral congress; the executive, consisting of the president; and the judicial, consisting of the supreme court and other federal courts. articles four, five and six embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. article seven establishes the procedure subsequently used by the thirteen states to ratify it. it is regarded as the oldest written and codified national constitution in force.
