PSY270H5 Chapter Notes - Chapter 7: Semantic Similarity, Semantic Memory, Semantic Network
Document Summary
Other concepts also become activated or primed. More and more distant concepts, connected by longer pathways, do not receive as much. These related concepts are not activated forever, but activation decays after some amount of. Ex: you are given the sentence, a robin is a bird and you have to make a true/false judgment. For this model, you would access concepts robin and bird in semantic memory and then compare the two feature sets. Stage i involves a rapid, global comparison of features, to compute similarities. Stage ii is slower, emphasizing more defining features. Collins and quillian model implies: ex: people verify the statement a pig is an animal faster than they verify a pig is a mammal , although collins and quillian model predicts the opposite result. Semantic memory also takes into account how we interact with the world through our senses and our actions, and so reflects embodied influences.
