Bottom-Up Theory- theory of perception that the data is coming into the senses is the primary data of perception. In bottom-up theory of speech perception- people perceive speech by focusing on information coming into their ears. The ear and brain somehow analyze the different features of baedgerz in order to put them together and determine what word it is. The problems with this approach is that they process is very slow. Analyzing each sound and then putting the sounds together is kind of a slow process, and a lot of people believe that there has to be something that speeds up the process and goes against a bottom-up theory. The speech acoustics vary from person to person and that can create a messy process. Not very efficient theory (but still popular)- - - Top-Down Theory- theory They include the analysis of incoming sounds but add more features that make the process more efficient An Interesting Experiment: One day two friends were walking to the park and one of them said, Do you know that b oy who was at the party last night?...
