The neural basis of overall similarity and single-dimension sorting
The ability to group stimuli into meaningful categories is fundamental to natural behavior. Raw perceptions would be useless without an ability to classify items as, for example, threat or food. Previous work suggests that people have a tendency to group stimuli either on the basis of a single dimension or by overall similarity (e.g., Milton, F.N., Longmore, C.A., and Wills, A.J. (2008). Proces...
متن کاملEye movements in overall similarity and single-dimension sorting
A free classification study is presented that uses eye-tracking to better characterize the strategies that are employed in the creation of overall similarity and single-dimension categories. The number of fixations across the dimensions and the proportion of dimensions fixated were significantly greater for overall similarity sorters than for single-dimension sorters. Single-dimension sorters g...
متن کاملIs overall similarity classification less effortful than single-dimension classification?
It is sometimes argued that the implementation of an overall similarity classification is less effortful than the implementation of a single-dimension classification. In the current article, we argue that the evidence securely in support of this view is limited, and report additional evidence in support of the opposite proposition--overall similarity classification is more effortful than single...
متن کاملThe Time Course of Overall Similarity Sorting in Free Classification
Previous work has shown that when participants are asked to sort a set of stimuli in the way that seems most natural, without any feedback from the experimenter, they have a preference to sort by a single dimension (e.g. Medin et al., 1987). This is perhaps surprising given that many natural categories are believed to be organized around a family resemblance structure in which categories are ma...

در این پایان نامه، در ابتدا برای مدول ها روی دامنه های پروفر شرایط معادل به دست آورده ایم و خواصی از ددکیند مدول ها روی دامنه های پروفر مشخص کرده ایم. در ادامه برای ددکیند مدول های با تولید متناهی روی حلقه های به طور صحیح بسته شرایط معادل به دست آورده ایم و ددکیند مدول های ضربی را مشخص کرده ایم. گزاره هایی در مورد بعد ددکیند مدول ها بیان کرده ایم. در پایان، قضایای lying over و going down را برا...
