Bottom-up models: the traditional view Bottom-up models argue that readers construct texts from the smallest to the largest units, like letters, words, phrases, clauses, sentences, texts as well as grammatical knowledge. In other words, bottom-up process refers to deriving the meaning of the text based on the incoming language data, from sounds, words, grammatical relationships, to meaning. Firstly, the reader is expected to become familiar with the words. Readers use top-down process when prior knowledge is used to understand the meaning of a text. Content words and contextual clues are used to form hypotheses for comprehension.

Bottom-up theories hypothesize that learning to read progresses from children learning the parts of language letters to understanding whole text meaning. Much like solving a jigsaw puzzle, bottom-up models of the reading process say that the reading puzzle is solved by beginning with an examination of each piece of the puzzle and then putting pieces together to make a picture. In their reading model, LaBerge and Samuels describe a concept called automatic information processing or automaticity. This popular model of the reading process hypothesizes that the human mind functions much like a computer and that visual input letters and words is sequentially entered into the mind of the reader. Because each computer and by comparison the human mind has a limited capacity available for multitasking, attention must be shifted from one job to another. An example of automaticity in action can be seen in the common skill of learning to ride a bike.
Top Down and Bottom up Processing
The way in which we process and therefore understand written and spoken texts is often described as either top-down or bottom-up. In our first language, we probably make use primarily of top-down processing. Our previous experience of watching TV news gives us some knowledge and expectations from which to make predictions about the likely content, as well as the style of language that will likely be used by presenters and journalists. L2 learners use more of a combination of bottom-up and top-down processing.
By not disclosing their evaluation policies it can not be replicated or understood by new organization members. In addition, creates a way for organizations to make up policies without getting feedback about evaluation best practices.
