Abstract: | |||||
This thesis is concerned with the structure of natural categories.
The traditional approach was that category exemplars are equal in terms
of membership and that definite boundaries exist between category
members and non-members. A view now widely held is that categories are
highly structured with well-defined cores, usually consisting of
prototypical instances, and fuzzy boundaries.
One question which has arisen is whether children also have
categories which are structured in this way. This question has
been addressed here by conducting a series of category sorting
experiments. The results of the first, second and third experiments
reported showed that children from three years of age do indeed have
categories with well-defined cores and fuzzy boundaries, and that
children and adults are influenced by exemplar typicality.
The fourth experiment showed that children and adults use the
same criteria for categorising when competing criteria are presented.
The fifth, sixth, seventh and eighth experiments investigated the
role played by locational information and order of presentation on
judgements of category membership. Both location and order were
shown to influence decisions about category membership. The
younger children in particular were affected by order and locational
information.
