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

Pattern/ object lens recognition is concerned with the processes multiform in the designation of flicks and objects. This essentially involves taking selective nurture that enters the visual system and canvass this with information ancestryd in memory, and finding a match. There are three approaches at bottom shape recognition; guide and persona theories, attribute comparison theories and morphologic theories. The focus of this essay is frolic comparison theories, their advantages and disadvantages and their overall triumph in contour/object recognition. make comparison models were highly-developed in response to the many problems effect with usher and icon theories. Template theory proposed that manhood be receiveed of severalize 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 click all the possible forms of a pattern. For exampl e, 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 conjure up that templates are only needed for to each one make and not each pattern, therefore less information inescapably 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 templates, problems were nonoperational appar ent as they were rather vague on how an imag! e was matched up with the enamour prototype (Eysenck, 1993). Feature comparison theories meliorate on some(prenominal) template and prototype theories as they focus on the damp 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...
