PSYCH 202 Lecture Notes - Lecture 4: Karl Lashley, Classical Conditioning, George Sperling
Document Summary
Learning and social adaptation depend on our memory capacities. When learning occurs, memories (specific types of knowledge seen in different patterns of motor, emotional, and verbal behavior) are established. When memories are destroyed, what was learned is altered fundamentally. Videoclip segment from zimbardo"s discovering psychology pbs series: Physical reality of memory: memories make lasting alterations in structure and function of central nervous system. Psychologists have called these physical traces of memory engrams . 3 types of engrams or memory traces : Procedural knowledge or memory (what you know how to do in behavior) Semantic or declarative knowledge or memory (what you know, as verbally represented); Episodic memory (recollection of experiences, (stories, another type of verbal or declarative knowledge process) Engrams determine your personal perspective on life. Karl lashley trained rats to learn mazes, then removed increasingly large areas of cortex. His conclusion: memory is not localized in any specific area of brain. (implication: memories are distributed across areas of cortex).
