Section 1 Taking In and Storing Information
Memory • Memory is the input, storage, and retrieval of what has been learned or experienced. • Processes of memory: • Encoding: The transformation of information so that the nervous system can process it. (Use senses to create and record a memory). • Three types: • Acoustic: remember things by saying them out loud repeatedly (Listening). • Visual: remember by trying to keep a mental picture of things (looking). • Semantic: remember things by understanding them or making sense of them. • Storage is the process where information is maintained over a period of time. • Retrieval is when the information is brought to mind or ‘remembered’ from storage.
Stages of memory • Sensory memory: quick memory storage which immediately follows a stimulus. • Capacity: all stimulus in the moment. • Duration: lasts a fraction of a second. • Short-term memory (working memory): memory that is limited to about 7 items and has low duration if not rehearsed. (working memory combines short-term and long-term memory for current information i.e. studying). • Capacity: about 7 items remembered. • Duration: less than 20 seconds if not rehearsed.
Primary-recency effect: refers to up to the first or last four things you are able to remember in a list. • Types of rehearsal: • Maintenance rehearsal is a system to remember by repeating information to one’s self (memorizing). • Chunking is grouping things together to remember them. • Long-term memory: the storage of information over long periods of time. • Types of long-term memory: • Semantic memory is our knowing of languages and its rules. • Episodic memory is our memory of events which occurred in one’s life with time. • Declarative memory is stored information that can be remembered voluntarily. • Procedural memory is the permanent storage of learned skills that don’t need to be remembered (i.e. writing).
Memory Centers in the Brain • Cortex: Stores memory • Short-term: our ability to remember words, facts, and events (declarative memory).The capacity of short-term memory depends on the activity in the cortex. • Long-term: ability to remember words, facts, and events (declarative memory) from the past depends on activity in the cortex. • Thalamus: information processing • Our ability to process sensory information to create memories. • Hippocampus: Ability to transfer facts or events from short-term into long-term memory. • Amygdala: Emotion Associations (associate information with emotions).
