to retain in the memory; keep in mind; remain aware of
to recall to the mind by an act or effort of memory; think of again
Forgetting
• Retroactive Interference: new information blocks out old information.
• Proactive Interference: old information blocks out new information.
Calling your new girlfriend by old girlfriends name.
Getting a new bus number and forgetting old bus number.
Sensory Memory• Storing an exact copy of incoming information for a few seconds; the first stage of memory– Icon: A fleeting mental image or visual representation
– Echo: After a sound is heard, a brief continuation of the sound in the auditory system
Short-Term Memory (STM)
• Holds small amounts of information briefly– Working Memory: Another name for STM; like a mental “scratchpad”
– Selective Attention: Focusing (voluntarily) on a selected portion of sensory input (e.g., selective hearing)
– Phonetically: Storing information by sound; how most things are stored in STM by sound (phonetically)
• Very sensitive to interruption or interference
Long-Term Memory (LTM)
• Storing information relatively permanently
• Stored on basis of meaning and importance
Eidetic Imagery (Somewhat Like Photographic Memory)
• Occurs when a person (usually a child) has visual images clear enough to be scanned or retained for at least 30 seconds
• Usually projected onto a “plain” surface, like a blank piece of paper
• Usually disappears during adolescence and is rare by adulthood
Theories of Forgetting
• Theories of forgetting can be difficult to test as we may in fact not forget, but have trouble retrieving information from storage.
• Therefore it is possible that these theories can explain why we are unable to retrieve a memory or why it is distorted.
Theories of Forgetting
• Two factors involved in forgetting:
• Accessibility: The information available can be accessed at a specific time/place.
• Availability: The information is represented in the memory.
Theories of Forgetting
Freud: Repression, conscious process of burying memories to protect ego.
The emotions associated with the repressed memory may be recovered, or express themselves through:
Dream Analysis.Hypnosis.Free Association.
Forgetting in STM.• Trace Decay: Unless
information is refreshed or rehearsed will spontaneously fade or decay over time.
• Displacement: Only a fixed number of slots in memory capacity. New information will displace old when capacity is reached.
Forgetting in LTM.
• Interference: More information will be stored and become confused together.
• Retrieval Failure: • Information may be
available but temporarily inaccessible
Cognition• Another term for thinking, knowing
and remembering
Maybe by studying the way we think, we can eventually think better.
Does the way we think really matter?
Concepts• A mental
grouping of similar objects, events, ideas or people.
• Concepts are similar to Piaget’s idea of….
In order to think about the world, we form……..
SchemasThese animals all look different, but they fall under our concept of “dogs”.
Prototypes
• A mental image or best example of a category.
We base our concepts on ….
•If a new object is similar to our prototype, we are better able to recognize it.
If this was my prototype of a man; then what am I?

Thinking
• Cognitive building blocks.
• The processes of thinking are distributed throughout the brain, especially in the frontal lobe

Thinking—Three Components (Mental Images)
• 1. Mental Images (mental representations of a previously stored sensory experience, including visual, auditory, etc.)
©John Wiley & Sons, Inc. 2007 Huffman: Psychology in Action (8e)
2. Concepts (mental representation of a group or category that shares similar characteristics)
– How do we learn concepts? a. Artificial concepts are formed by logical, specific
rules.b. Natural concepts/prototypes are formed by our
experiences in everyday life.c. Hierarchies help us group concepts into
subcategories within broader categories.
