Abstract
In this paper we present models of how meaning is represented in the brain/mind, based
upon the assumption that children develop meaning representations for words using two main
sources of information: information derived from their concrete experience with objects and
events in the world (which we refer to as attributional information) and information implic-
itly derived from exposure to language (which we refer to as distributional information). In
the first part of the paper we present a model developed using self-organising maps (SOMs)
starting from speaker-generated features (properties that speakers considered to be important
in defining and describing the meaning of a word). This model captures meaning similarity
between words based solely upon attributional information and has been shown to be success-
ful in predicting a number of behavioural semantic effects. In the second part of the paper,
