Perception is the process that occurs when the brain processes sensory stimuli and translates them in a way that a person can understand. Perception is not usually a conscious process; furthermore, sensing a particular stimulus is a different process than the interpretation (i.e. perception) of that stimulus.

A team of perception researchers decided to test the difference between sensation and perception by testing the reading speed of a paragraph in three conditions. In the first condition, the researchers correctly spelled the words in the sentences. In the second condition, they had the same words with the letters randomly jumbled within each word; however, the first and last letter of each word remained in the correct position. In the third condition, researchers used the same words and randomly jumbled every letter in each word, including the first and last letters. Sample sentences from the paragraphs are below:

1). Mary crossed the street to purchase a cookie after lunch.

2). Mray csorsed the sretet to pruachse a ckooie atfer lnuch.

3). Rmya rsocsed het teerst to curaepshs a okocei feart culhn.

The researchers timed how long it took for the participants to correctly say a sentence fluently. They found that participants in condition three took significantly more time to read the sentence fluently, whereas they found no significant difference in the average amount of time it took participants to read the passage in condition one compared to condition two.

Suppose the researchers were also interested in the amount of time it took the participants in each condition to read each letter fluently (as opposed to each word). In order to test this phenomenon, participants across conditions were instructed to read each letter aloud as quickly and as correctly as possible. They found no group differences in letter reading speed or accuracy. Based on these results, the researchers would most likely conclude which of the following?

The observation that participants did not differ in reading time between conditions one and two illustrates that humans rely on which of the following principles when reading?
