PSYC 220 Lecture Notes - Lecture 21: Tacit Knowledge, Working Memory, Underlying Representation
Document Summary
Study question: draw a propositional network that represents the meaning in simple sentences. For example, the old car pulling the tractor climbed the hill. Analogical representation: representation shares physical characteristics with the object. Imagine an elephant: discriminability effect: the greater the difference between two stimuli, the faster the decision hat they differ (ex. Which dot is higher?: the symbolic difference effect, the symbolic discriminability effect: a discriminability effect that it based on long term memory knowledge. Vs. a donkey or a horse: effects mirror (physical) distance effect (closer in size, longer it takes to decide which is bigger) Representation in semantic memory: proposition: a simple semantic relation between 2 concepts, basic unit of meaning, the simplest sentence that can take on a truth value, ex. A shark has fins [tlc: shark is a fish-which has fins; spreading activation: shark is a fish link, shark has fins link; propositional representation: shark (agent), fins (characteristic)]
