The proposed vigilance parameter update rule can help improving categorization performance in the aspect of category number stability and solve the problem of selecting initial vigilance parameter prior to pattern categorization in traditional ART networks.
For rule-based categorization, only one stimulus dimension is relevant, while for feature-based categorization multiple dimensions are relevant.
These regions showed less activation during rule-based categorization, in which visual similarity was less important to perform the task.
This test evaluates abstract thinking ability, such as rule-based categorization [ 8], and is a measure for other aspects of the executive functions, including cognitive flexibility [ 9, 10].
In our task, for example, a shift between rules within the same category may have been executed without reference to the link between frame color and categorization rule; to perform such a switch, it was necessary only to see that frame color had changed and to retrieve the other rule relevant to the current set of stimuli.
Also, because honey bees express a rich and well-characterized repertoire of complex behaviors, such as extinction learning, stimulus categorization, rule learning, and advanced navigation [17] [19], they provide an excellent opportunity for examining generic features of brain aging.
Our results point to a fast recognition mechanism based on low frequency contents that fits with Bar's framework, although our use of equalized scenes makes it unlikely that a simple categorization rule could be used.
These findings may provide guidelines for new bottle designs that capitalize on existing categorization rules based on consumer perception.
The approach is centred around the view that categorization rules can often be seen as approximations of linear (or at least monotonic) mappings between conceptual spaces.
The model framework relies on the basic categorization rules of Kano's quality model (see [12]) applied to the determined SQ-attributes.
