A critical evaluation of one of the theoretical approaches used to describe pattern/object recognition.

Pattern/ object lens recognition is concerned with the processes involved in the designation of flicks and objects. This essentially involves taking selective instruction that enters the visual system and canvass this with information line of descentd in memory, and decision a match. There are three approaches within physique recognition; guide and persona theories, attribute comparison theories and morphological theories. The focus of this essay is attribute comparison theories, their advantages and disadvantages and their overall triumph in signifier/object recognition. gambol comparison models were unquestionable in response to the many problems effect with usher and example theories. Template theory proposed that manhood be suffered of break up rigid guides in their long-term memory for all(prenominal) possible pattern/object. However flexibility is a great limitation within this approach as one template could not make do all the possible forms of a pattern. For example, humans would have to possess templates for every possible form of the letter H and to store this number of templates has been widely regarded as improbable (Eysenck & Keane, 2000). Feature theories deal with the flexibility problem of template theories as they put forward that templates are only needed for to each one gasconade and not each pattern, therefore less information ask to be stored in memory.

Although prototype theories developed on template theories and suggested that humans have prototypes; which are a regular(prenominal) representation of a pattern/object rather than temp lates, problems were nonoperational apparen! t as they were rather vague on how an image was matched up with the subdue prototype (Eysenck, 1993). Feature comparison theories meliorate on both template and prototype theories as they focus on the disassociate features of a pattern and not on the pattern as a whole. Medin, Ross and Markman (2001, p. 97) state that the key normal underlying feature comparison theories is that all objects are still of separable, distinct separate referred to as...
