It was assumed that memory can be disrupted or interfered with by what we have previously learned or by what we will learn in the future. This idea suggests that information in long term memory may become confused or combined with other information during encoding thus distorting or disrupting memories.

Failures of State by Jonathan Calvert, George Arbuthnott

Forgetting information from short term memory (STM) can be explained using the theories of trace decay and displacement. Material failure can be distinguished in two broader categories depending on the scale in which the material is examined:

In mathematical terms, failure theory is expressed in the form of various failure criteria which are valid for specific materials. Failure criteria are functions in stress or strain space which separate "failed" states from "unfailed" states. A precise physical definition of a "failed" state is not easily quantified and several working definitions are in use in the engineering community. Quite often, phenomenological failure criteria of the same form are used to predict brittle failure and ductile yields. This theory suggests short-term memory can only hold information for between 15 and 30 seconds unless it is rehearsed. After this time the information / trace decays and fades away. The maximum principal stress and strain criteria continue to be widely used in spite of severe shortcomings.

He has been published in peer-reviewed journals, including the Journal of Clinical Psychology. For example, many people say they can”t remember much about their childhood or their school days. But returning to the house in which they spent their childhood or attending a school reunion often provides retrieval cues which trigger a flood of memories. References

Lloyd George remained chancellor of the exchequer through the early years of World War One. In 1915 he was appointed minister of munitions in Asquith's wartime coalition government. In July 1916 he became secretary of state for war, but was increasingly critical of Asquith. In December 1916, with the support of the Conservative and Labour leaders, he replaced Asquith as prime minister. Lloyd George's achievements in the last two years of the war included persuading the Royal Navy to introduce the convoy system and the unification of the Allied military command under the French general Ferdinand Foch.

The following represent the most common yield criterion as applied to an isotropic material (uniform properties in all directions). Other equations have been proposed or are used in specialist situations. a b Patterson, Christina.

Proactive interference (pro=forward) occurs when you cannot learn a new task because of an old task that had been learned. When what we already know interferes with what we are currently learning – where old memories disrupt new memories.

Numerous other phenomenological failure criteria can be found in the engineering literature. The degree of success of these criteria in predicting failure has been limited. Some popular failure criteria for various type of materials are:
