The Norton Psychology Labs: Feature Net
The Norton Psychology Labs: Feature Net
Questions
1. fiogf49gjkf0d How does the structure of the feature net lead to more efficient word recognition? Why does it sometimes lead to errors? |
|
2. fiogf49gjkf0d Contrast the terms "bottom-up processing" and "top-down processing." How do these two terms relate to the feature net? |
|
3. How might cognitive mechanisms like those of the feature net explain proofreading errors—that is, failing to notice a typographical error in a written document? |

The Norton Psychology Labs: Word Superiority Effect
The Norton Psychology Labs: Word Superiority Effect
Questions
1. fiogf49gjkf0d Looking at the data that you generated for this exercise, for which type of trial was your percentage higher—words or characters? What percentage correct would be expected in this two-alternative forced-choice task if a participant were randomly guessing? |
|
2. fiogf49gjkf0d How does a system like the feature net explain the word superiority effect? |
|
3. fiogf49gjkf0d What is the phonemic-restoration effect, and how is it similar to the word-superiority effect? |

The Norton Psychology Labs: Lexical Decision Task
The Norton Psychology Labs: Lexical Decision Task
Questions
1. fiogf49gjkf0d How can the semantic-priming effects demonstrated by this experiment be explained in terms of a network model and spreading activation? |
|
2. fiogf49gjkf0d Looking at the data you generated for this task, did you demonstrate any general tendency to respond more quickly to words compared to nonwords? Why might it take longer to make a "word" response compared to a "nonword" response? |
|
3. fiogf49gjkf0d You may have noticed that some words appeared more than once during this exercise. How might an experimenter ensure that effects of repetition priming are counterbalanced correctly in a semantic-priming experiment? |

The Norton Psychology Labs: Sentence Verification
The Norton Psychology Labs: Sentence Verification
Questions
1. fiogf49gjkf0d Why do we say that the network model of Collins and Quillian has a "hierarchical" structure? How does this structure explain some of the effects observed in the sentence verification task? |
|
2. fiogf49gjkf0d Why does it take more time to verify a sentence like "A canary breathes" compared to "A canary can sing"? |
|
3. In this exercise, you answered questions not only about animals but also about plants, drinks, and furniture. Draw a hierarchy illustrating how your knowledge of one of these three categories might be represented. (Use the animal-knowledge hierarchy shown in the "theory" section of this exercise as an example.) |

The Norton Psychology Labs: Word Frequency
The Norton Psychology Labs: Word Frequency
Questions
1. fiogf49gjkf0d Looking at the data you generated for this task, describe the effect of word frequency and the effect of priming ("seen" versus "not seen"). How would a cognitive psychologist explain these effects? |
|
2. fiogf49gjkf0d Give an example of how word frequency plays a role in more complex language processing, such as the syntactic parsing of a sentence. |
|
3. fiogf49gjkf0d How might the lexical decision task be used in another experimental design to test the notion that garden-path sentences are difficult to process? |
