This simplified example of a research paper will look at two of the bottom-up process theories that we use for perception. The two processes that will be evaluated in this paper are Template Theories and a Feature Theory known as Selfridge's Pandemonium Model. This paper will include hypothetical experiments that could be used to test both theories. It also includes evidence that is for and against both of these theories.
             When we are presented with a familiar two-dimensional pattern, we are often able to recognize it. This is often more of an achievement than it might seem. For example, we can read hand-written words written in different ways and we can read text printed in several fonts or in different orientations. In other words, our visual system operates in a flexible fashion to make sense of the two-dimensional patterns we encounter every day. The central issue that has been addressed by theorists is how to account for this flexibility. The two theories that will be discussed and researched in this paper are Template Theories and Selfridge's Pandemonium Model. First we will research Template Theories.
             One of the simplest approaches to pattern recognition is to assume that there is a template or miniature copy of each of the patterns we know stored within long-term memory. According to simple template theories, all that happens in pattern recognition is that a visual stimulus is matched with whichever template provides the best fit. The main problem is that the basic template theory does not explain how we manage to recognize any given pattern in spite of great variability in the visual stimulus. Another theory that can explain our visual perception is a feature theory by the name of Selfridge's Pandemonium Model. Visual stimuli can be thought of as consisting of a number of features. For example, the human body consists of two legs, two arms, a trunk and so on, and a face consists of hair, two eyes...
