What we'll be discussing today will be the more "typical" atypical items, if you will.So here we go!
Such an account would have to stipulate that the M100 frequency effect obtained for the atypical items is driven by the subset of the items in which stroke similarity occurs, and that for those items, this subtle similarity is powerful enough to activate the unseen typical word form to such an extent that the amplitude of the M100 response reflects the frequency of the unseen form.
Error analysis indicated participants frequently gave higher typicality responses for atypical items.
However, Plaut's study found retraining the lesioned computer network using atypical items resulted in generalisation to untreated typical items.
While retraining using typical items resulted in improved naming for other typical items, results showed no generalisation and, notably, deterioration in naming performance for untreated atypical items.
This version of the SIGH-SAD consists of the HDRS 17-item scale plus the first 7 atypical items (i.e., excluding Reverse Diurnal Variation).
Results showed poorer performance for atypical items, supporting the prediction that lower typicality items would be more vulnerable following damage in this area.
Through connectionist modelling techniques, the concept of a multi-dimensional semantic space has been proposed with typical items occupying a central area with a greater number of shared, overlapping features and atypical items, with idiosyncratic features, found on the periphery.
Further mood measurements were made at baseline and end-of-treatment using the SIGH_SAD_SR, a self-rating form including the Hamilton Depression Rating Scale (HDRS, 17 items used) and atypical items previously shown to be responsive to light treatment [ 31].
Given their volume as well as their fragmented and often mechanical acquisition, the data contain atypical items (outliers), which impede generalization as well as many redundant or irrelevant variables.
