MATH 204 - ONE-WAY ANOVA WORKED EXAMPLE

A standard model of memory is that the degree to which the subject remembers verbal material is a function of the degree to which it was processed when it was initially presented.

• The Imagery group was instructed to try to form vivid images of each word.

• The Intentional group was told to read through the list and to memorize the words for later recall.

Counting	Rhyming	Adjective	Imagery	Intentional

Research question: Does the level of processing required when material is processed affect how much material is remembered ?
