In summarizing, the time course of processing visual information may be characterized by three consecutive time windows that are associated with different ERP components, sensory encoding (around about 80 ms), early categorization (around about 100 ms) and stimulus recognition (around about 150 ms).
According to the Threshold Theory (Hampton, 1995, 2007) semantic categorization decisions come about through the placement of a threshold criterion along a dimension that represents items' similarity to the category representation.
In the experiment that follows two groups of participants made either recognition or categorization decisions about the same set of test items.
There were also two control groups who made either recognition or categorization decisions about the same sets of items but who saw no exemplars in the study period.
Consequently, the semantic similarity score between G22 and G32 is Conventional semantic similarity measures were developed to assess how similar two GO terms are, but categorization is about assessing how well a specific term belongs to another term or a group of other terms.
For 283 web pages (about 75%), all 5 observers agreed with our categorization, and for 334 (about 88%) at least 4 of 5 agreed.
Intra-observer agreement was evaluated using the kappa coefficient, since it requires no assumption about correct categorization and includes correction for the degree of agreement that would be expected by chance alone[ 12].
First, we count if we can, but counting depends a great deal on previous assumptions about categorization.
With categorization, people learn about new concepts through an internal transfer of knowledge.
For further discussion of the debates about categorization in cognitive science see Lakoff (1987) and Rakison and Oakes (2003).
