PSYCH 120A Chapter Notes - Chapter ZAPS 11-13: Dorsolateral Prefrontal Cortex, Stroop Effect, Occipital Lobe
Document Summary
Reaction time: how long it takes for psychological processes to occur in our brains. Stroop test: designed to measure conflicts between two sensory inputs. Cognition: mental activity that includes thinking and understanding gained from thinking. Semantic inference: being distracted by the meaning of words. Brain automatically recognizes meaning even when the chief task is to recognize color. Recognizing word meaning and color use different processes. Wernicke"s area: part of the temporal lobe that determines meaning. Color of text initially processed by the occipital lobe. Dorsolateral prefrontal cortex: evaluates the two sources of info, ignores irrelevant one and makes decision. When subjects were hypnotized and told they would be seeing meaningless symbols, they did not show the typical results. Had the same rxn times for congruent and incongruent trials. Semantic distance between two words is determined by the connections in the network, defined as the shortest interval between these two words.
