Study Notes
Brain Areas Associated with Memory
- Scientists believe specific brain areas specialize in different memory types.
- The temporal lobe is linked to sensory memory.
- The frontal lobe is associated with short- and long-term memory.
- The temporal and occipital lobes are associated with sensation, thus involved in sensory memory.
- Sensory memory is a temporary holding area for sensory information, lasting a few seconds.
Three Stages of Learning and Memory
- Encoding: initial learning of information.
- Storage: maintaining information over time.
- Retrieval: accessing information when needed.
Encoding
- Memory encoding converts information into a format stored in the brain for indefinite recall.
- Information is encoded into short- or long-term memory.
Memory Storage
- Memories are modified and reconstructed during retrieval and recall.
- Encoding filters and modifies the information for storage.
- Memory storage involves altering neural pathways, also known as long-term potentiation.
Memory Retrieval
- Memory retrieval involves recalling stored information.
- Two types of retrieval are recall and recognition.
- Recall requires retrieving information from memory without cues.
- Recognition involves identifying information with cues.
Serial Recall
- Recalling items in the order they occur.
- Recent events, closer in time, are more easily recalled.
- Primacy effect: remembering items at the beginning of a list better.
- Recency effect: remembering items at the end of a list better.
Free Recall
- Recalling items in any order.
- Primacy and recency effects also influence free recall.
Cued Recall
- Recalling through cues or prompts.
- Stronger cues lead to better retrieval.
Retrieval Failure
- A failure to recall stored information.
- Decay and interference can cause retrieval failure.
Sensory Memory
- Brieftly holding sensory information
- Three types: iconic (visual), echoic (auditory), and haptic (touch).
Chunking
- Grouping items to improve sequential memory performance.
- Improves how much information can be recalled.
Short-Term Memory (STM)
- Temporary memory system processing incoming sensory information.
- Sometimes called working memory.
- Used for both temporary storage and manipulation of information.
Long-Term Memory (LTM)
- Long-term storage of information for days, months, or years.
- Permanent change in neural connections.
- Two main types: explicit and implicit
Explicit Memory (Declarative Memory)
- Consciously recalled information.
- Semantic memory: general knowledge
- Episodic memory: personal experiences
Implicit Memory (Non-declarative Memory)
- Unconscious memory influencing behavior.
- Procedural memory: knowing how to do things (skills).
- Classical conditioning: associating stimuli and responses.
- Priming: Changes in behavior due to recent/frequent experiences.
Forgetting
- Loss of memory over time, or difficulty retrieving specific information.
- Decay: fading of memory over time.
- Interference: other memories hinder recall.
- Retrieval failure: lack of cues to access the desired memory.
Language Development
- Language is a system of communication using symbols to create meaning.
- Key Components:
- Phoneme: Smallest unit of sound with meaning difference.
- Morpheme: Smallest unit of meaning.
- Semantics: Rules for obtaining meaning from morphemes.
- Syntax: Rules for constructing sentences.
- Pragmatics: Social use of language.
Language Developmental Progression
- Babies develop language through cooing, babbling, and gesturing.
- Understanding language precedes production.
- Language development progresses gradually.
Infant-Directed Speech
- Adults use special variations of speech with infants.
- Characteristics include higher pitch, exaggeration, and repetition.
