Definition: The tendency to remember the first items in a list better than middle items.
Why?: Early items get more rehearsal and move into long-term memory.
Example: If you hear a list of groceries (milk, bread, eggs, oranges, pasta, cereal), you’re more likely to recall "milk" and "bread" later.
Application: Helps explain why studying earlier topics in a lecture is easier to recall.
Definition: The tendency to remember the last items in a list better than middle items.
Why?: Items at the end of the list are still in short-term memory.
Example: In a phone number list, you might remember the last few digits best.
Application: This effect disappears if there’s a delay before recall, like distraction or another task.
Definition: A type of sensory memory for visual stimuli that lasts for a fraction of a second.
Example: If you see a flash of lightning, you briefly retain the image after it disappears.
Application: Explains why we can process fast-moving visuals (movies, scrolling text).
Partial Report: When asked to recall only part of the information (e.g., a row of letters), performance is betterthan when recalling everything.
Whole Report: When asked to recall everything, performance drops.
Why?: Sensory memory fades quickly, and partial reports help isolate what we need to recall.
Central Executive: Directs attention, coordinates tasks.
Phonological Loop: Stores and processes verbal info (repeating phone numbers).
Visuospatial Sketchpad: Stores and manipulates visual/spatial info (mental map of a room).
Episodic Buffer: Links info across domains (linking a story to a personal memory).
Definition: The ability to hold and manipulate information temporarily.
Applications: High working memory = better at multitasking, problem-solving, and reasoning.
Shallow Processing: Based on surface features (e.g., font, sound).
Deep Processing: Based on meaning, leads to better recall.
Example: Remembering “dog” because you think about a pet you had vs. just reading the word.
Definition: Memory is better when retrieval matches encoding.
Example: If you study by writing answers (recall-based), you’ll do better on an exam with essay questions than multiple-choice.
Early Selection: Filters out irrelevant information before processing meaning.
Late Selection: Processes all information, filtering occurs after meaning is analyzed.
Example: Cocktail party effect—hearing your name in a noisy room supports late selection.
Definition: Attention is captured automatically by stimuli (e.g., a loud noise, flashing light).
Example: Looking towards a fire alarm sound without consciously deciding to.
Definition: Interference between automatic and controlled processing.
Example: Naming the color of the word RED when it’s printed in blue.
Application: Demonstrates how reading (automatic) interferes with naming colors (controlled).
Feature Search: Looking for a single distinguishing feature (e.g., finding a red circle among blue ones).
Conjunction Search: Requires looking for a combination of features (e.g., a red circle among red squares and blue circles).
Definition: The ability to detect differences between shades or brightness.
Example: Seeing a white object against a slightly gray background.
Definition: Perception of a circle's size is influenced by surrounding circles.
Example: A central circle appears smaller when surrounded by larger circles.
Episodic: Personal experiences (e.g., your last birthday).
Semantic: General knowledge (e.g., knowing that Paris is the capital of France).
Implicit (unconscious): Skills, habits (e.g., riding a bike).
Explicit (conscious): Facts, personal experiences.
Flashbulb Memory: Vivid, detailed memory of emotionally significant events (e.g., where you were during a major event).
Illusions of Memory: Memories can feel real but contain errors (e.g., thinking you remember 9/11 details perfectly when memories have changed over time).
Definition: The inability to recall memories from early childhood.
Why?: Brain structures (hippocampus) aren’t fully developed.
Definition: People recall more memories from ages 10-30 compared to other periods.
Why?: Many first-time experiences, identity formation.
Definition: Memory is better when retrieval occurs in the same context as encoding.
Example: Studying in a quiet room helps recall better on a quiet exam day.
What he could do: Learn new motor skills (implicit memory intact).
What he couldn’t do: Form new explicit memories.
Memory Illusions: False memories (e.g., recalling "sleep" in a word list with "bed," "dream," and "tired").
Fluency Illusion: Feeling like you know something just because it's familiar, but you can’t recall it under pressure.
Prototype Theory: We categorize based on an "average" representation (e.g., generic dog image).
Exemplar Theory: We categorize based on actual stored examples (e.g., your childhood dog).
Superordinate: Broad category (e.g., "animal").
Basic Level: More specific, but most useful (e.g., "dog").
Subordinate: Even more specific (e.g., "golden retriever").
Why Important?: The basic level is where we naturally categorize best.
