Document Summary
Hot cognition: emotions as a source of information for cognitive processes, e. g. emotional prosody in language: Important language: beyond meaning of individual words, e. g. tone of voice. Basic emotion: facial expressions, provide information to cognitive system, specifically non verbal. Interested in how emotion affects memory: participants told to study images and rate them on dimensions of valence and arousal, memory was then tested on the images, results: Semantic networks: collins and quill (1969), proposed first semantic network model of semantic knowledge, hierarchical semantic network: Interconnected nodes: distance between nodes represents the similarity between the items, defined concepts in regards to its relationship to other nodes, propositional method, the diagram: Spreading activation (still used): collins & quill: Indicates semantic priming: that a response to a target (e. g. doctor) is preceded by a semantically related prime (e. g. nurse) If its negative, the sadness mode may be activated: other nodes/behaviours/memories will be affected, e. g. sad memories will become more available.
