Homework 5 Stephanie Leath October 19, 2009 Abstract The theory of object recognition investigates how two-dimensional objects are processed in the brain. It shows how figures are broken down into distinctive features, or smaller pieces of the whole object, and how the brain uses specific neurons to interpret and determine what the object is. A group of 42 participants, consisting of 12 males and 32 females, were tested using a feature analysis program to test how fast and accurate they were to determine if a letter pair was similar or different using several different examples of letter pairs such as, EF, CG, or AL. The results showed a significant difference in letter pairs that were similar and letter pairs that were different. The reaction time for similar letter pairs was significantly slower than different letter pairs.

Unformatted text preview: It was determined that error rate was also significantly higher for similar letter pairs. The findings of this experiment showed that people have a more difficult time distinguishing between two objects that are similar than two objects that are the same.
