Adaptive Learning: Smart Space
|Established cognitive science holds that "cognitive processes such as categorization and object recognition operate on a fixed set of
perceptual or conceptual features, which are the building blocks for complex object representations." Schyns, Goldstone & Thibaut argue that
categorization and object recognition often require the creation of new features. "The featural repertoire, rather than being fixed, is dependent
on situational demands, novel categorization requirements, and environmental contingencies." (BBS p. 1) SGT provide an account of feature learning
in which the components of a representation have close ties to the categorization history of the organism. (BBS p. 2 ) They write:
"The individual knows what the categories are from external feedback, that is, the consequences of their miscategorizations. . .
Flexible features open the possibility that the same input is
differently perceived and analyzed before being categorized. Hence a complete theory of conceptual development should not only explain
the ways in which object features are combined to form concepts, it should also explain the development of the features participating in the
analysis of the input." (BBS p. 5 )
|Two types of category learning should be distinguished. Fixed space category learning occurs when new categorizations are
representable with the available feature set. Flexible space category learning occurs when new categorizations cannot be represented with
the features available. Whether fixed or flexible, learning depends on the featural contrasts and similarities between the new category to be represented and the individual's existing concepts.

2. The intention is to describe the multiple dimensions of a given environment where each RCSP has the opportunity to receive the same stimuli, but through its individualized filtering process it collects different stimuli, and/or perceives the same stimuli differently.
3. Together the stimuli, physical properties, to which the organism is sensitive define a multideminsional space. The space is defined by just those physical dimensions that are important to the organism.
4. Dependent on project goal (what is to be described), different perceptual capabilities are attributed to the various RCSPs. Though a project goal isn't necessary but is allowed to emerge.
5. Some behavior makes sense in terms of the events that preceed it; other behavior makes more sense in terms of the events that follow it. Reflexes are behavior of the first kind. Operant behavior is guided by its consequences where operant refers to an essential property of a goal directed behavior: that it have some effect on the environment.
6. Behavior is guided in some way by the discrepancy between the present state of affairs and some often unknown ideal state.
