ABSTRACT
The activation-selection model (ASM) of determining the meaning of an ambiguous word is unique in that it is able to account for the long-term effects of meaning selection without an explicit mechanism for suppressing the representation of the nonselected meaning. The model assumes that a meaning is selected when a threshold number of attributes associated with that particular meaning are activated. When a meaning is selected, the ASM assumes that the weights of the attributes that are associated with the chosen meaning are increased. This two-phase process (transient activation followed by long-term weight changes) provides a mechanism by which meaning selection at one time can affect meaning selection at a much later time. The ASM can explain the results of the presently reported experiments, in which the meaning selected for a homophone presented in an unbiased context is affected by multiple previous presentations of the homophone in different contexts. In particular, although participants who are initially oriented toward the secondary meaning of a homophone show an increased proportion of dominant responses when next primed by the dominant meaning of the homophone, the proportion of dominant responses decreases to below baseline levels when the homophone is later presented in a neutral context, indicating the lasting influence of the initial secondary meaning context.
