The Lexical Decision Experiment
Using CogLab, complete the lexical decision experiment and create a report on the experiment.
In your report, write a brief introduction explaining the organization of lexicons. In addition, include some representative researches on lexical decision. Next, in the Methods section, describe the process that you followed to complete the experiment, including a description of the materials used and the stimuli. Make sure to include enough information so that others can also perform the same experiment successfully.
Finally, describe the experimental results. In addition, determine whether your results showed semantic priming. Provide a rationale to support your answer. Summarize your report, including answers to the following questions:
- Were the results in accordance with your expectations? Provide a rationale to support your answer.
- Did anything about the experiment surprise you? If yes, what? Did you respond faster to words or nonwords?
- In your opinion, what factors would influence the results of the lexical decision experiment?

The Lexical Decision Experiment
Most psychologists agree that a human language is organized and assessed in the human mind in the form of lexicons.
Organization of Lexicons
The lexicon of a language is its vocabulary, including terms, subjects, styles, and expressions used when communicating. In other words, it is the knowledge that a native speaker has about a language. Unlike a dictionary, which is arranged alphabetically, a lexicon is organized by:
- Semantics: This refers to what a word means. For example, knife and fork are placed far apart in the dictionary but are ?close? to each other in the lexicon because they are both items of cutlery.
- Phonology: This refers to how a word sounds, for example, book and look, beak and sleek, and kite and pike.
- Parts of speech: This refers to the way a word functions in a language, for example, nouns, verbs, adjectives, adverbs, prepositions, and conjunctions.
- Relationship between words and phrases: This refers to what a word can precede or follow and how a word can be modified, for example, synonyms such as youth and adolescent, antonyms such as man and woman, and polysemy words (same word having two or more distinct meanings) such as check (bank) and check (chess).

Organization of Lexicons
The lexicon of a language is its vocabulary, including terms, subjects, styles, and expressions
used when communicating. In other words, it is the knowledge that a native speaker has about a
language. Unlike a dictionary, which is arranged alphabetically, a lexicon is organized by:
? Semantics: This refers to what a word means. For example, knife and fork are placed far
apart in the dictionary but are ?close? to each other in the lexicon because they are both

? Phonology: This refers to how a word sounds, for example, book and look, beak and
sleek, and kite and pike.
? Parts of speech: This refers to the way a word functions in a language, for example,
nouns, verbs, adjectives, adverbs, prepositions, and conjunctions.
? Relationship between words and phrases: This refers to what a word can precede or
follow and how a word can be modified, for example, synonyms such as youth and
