Term
Stage Theory

Definition
The Neural code for STM is dynamic, its based of the pattern of activity among a group of cells.
Term
Neural Code for LTM

Definition
The process when a memory trace changes from dynamic to structural.

Amnesia
Definition
Loss of memory that occurs as a result of physical or psychological trauma.

Definition
Loss of memory that occurred before the trauma occurred.
Term
Anterograde Amnesia
Definition
Inability to form new memories from the time after the trauma.

Term
Retroactive Interference

Episodic Memory
Definition
An event with a specific time and place.

Term
Generic/Semantic Memory
Definition
Facts, concepts and meanings whose origin and or location is unknown.
Term
Craik and Tulving's Depth of Processing
Definition
The deeper an item is processed, the easier it is to recall.
Term
Explicit
Definition
Memory retrieval in which there is an awareness of remembering at the time of retrieval.
Term
Recall
Definition
Drawing information from memory in response to a cue or question.
Term
Recognition
Definition
Presented with a name or face and ask if you have encountered it before.
Term
Implicit
Definition
Memory retrieval in which there is no awareness of remembering at the time of retrieval.
Term
Priming
Definition
Phenomenon wherein giving a participant advance knowledge about or exposure to a stimulus can increase the ease of recall or recognition.
Term
Declarative Memory
Definition
The part of long-term memory where factual information is stored, such as mathematical formulas, vocabulary, and life events.
Term
Procedural Knowledge
Definition
Knowing how to do things such as riding a bike, tying a shoe lace.
- Skills
Term
Encoding Specificity principal
Definition
The principal that the environment cues present at the time information is encoded into long-term memory serve as the best retrieval cues fro the information.
Term
Retrieval Cue
Definition
A stimulus that aids in retrieval of a memory.
- Should be as much like the context during encoding.
- Figure, data, table, diagram, etc.
Furniture would not be a good cue to use.
Term
Johannas Muller's Doctrine of Specific Nerve Energies
Definition
Quality of sensation (visual, auditory, toucn,ect) depends on which nerve fibers are stimulated- not on the stimulus itself.
• Fibers of optic nerve are normally stimulated by light
• May also be stimulated by pressure, electric current, and so on.
• Any stimulation will yield experience of light
• Any sensory experience must have corresponding set of nerve fibers: experiences of brightness, color, loudness, pitch, ect.
Term
Loftus and Palmer Experiment on Retrieval.
Definition
At least in part, memory involves reconstruction of remembered information.
- Memory can be distorted with other information.
Term
Light
Definition
A form of electromagnetic radiation.
Term
Electromagnetic Spectrum
Definition
Gamma, X-Ray, UV, *Color*, Infrared, Microwave, Radar, FM, TV, AM
Term
Wave Lengths of Visible Light
Definition
Short - Blue
Medium - Green
Long - Red
Term
Young-Helmholtz's Trichromatic Theory
Definition
All visible colors are mixtures of blue, green and red and are based on responses to the cone types.
Term
Opponent Process Theory
Definition
Hering's theory that color perception is based on three systems of color opposites blue-yellow, red-green, and black-white
Short wavelength- 440nm
Medium Wavelength- 530nm
Long Wavelength- 560nm
Term
Retina
Definition
The retina constists of receptors (Cones/Rods), bipolar cells, gaglion cells and others.
Term
Optic Nerve
Definition
Bundle of axons of gaglion cells leading out the back of the eye to brain. Forms blind spot.
Term
Fovea
Definition
Central depression in retina where cones are most densely packed.
- Most acute vision.
Term
Rods
Definition
Very sensitive cells, responsible for detecting black/white lights.
- Night vision
- 2 types
Term
Cones
Definition
Less sensitive than rod cells, responsible for color and day time vision.
- 3 types
- Located in the Fovea
Term
Sensation
Definition
Basic, primitive mental state corresponding to energies in the the environment; experiences of the world.

Mental state corresponding to properties of objects and events in environment; knowledge of world.
Term
Distal Stimulus
Definition
An object in the real world.
Term
Proximal Stimulus
Definition
The retinal image of the distal stimulus.
Term
Issues with Retinal Images
Definition
Inverted Image
Ambiguous - "Size distance trade off
Two Dimensional - Image is flat and curved.

*Perception takes place in the brain!
Term
Semantic Memory
Definition
The portion of Generic Memory that contains the meanings and concepts.
Term
Associative Links
Definition
In network-based models of mental representation, connections between the symbols (or nodes) in the network.
- Civil war makes us think of Abe Lincoln.
Term
Semantic Priming
Definition
Theory that related items are easier to process than unrelated items.
- Nurse - Doctor is easier to recognize than Nurse - Apple.
Term
Weber's Law
Definition
The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount).
- Ability to tell the differences between two candles.
- The amount is proportional.
Term
Lateral Inhibition
Definition
The reduction of activity in one neuron by activity in neighboring neurons.
Term
Brightness Contrast
Definition
The increase or decrease in an object's apparent brightness by comparison to objects around it.
- Grey looks brighter on a black background than a white background.
Term
Mach Bands
Definition
A tendency to see light and dark bars near the borders between light and dark areas. (Lighter when bordering a darker color and darker when bordering a lighter color)
Term
Henry Molaison
Definition
A man who suffered from sever epilepsy, neurosurgeons bilaterally removwed 2/3 if his hippocampusm which is important in many learning and memory tasks. he had severe anterograde amnesia, mild retrograde amnesia. He retained intact working memory but was unable to learn new things.
Term
Thomas Young
Definition
Came up with the trichromatic theory.
Term
Elizabeth Loftus
Definition
Studied cognition and memory; studied repressed memories and false memories; showed how easily memories could be changed and falsely created by techniques such as leading questions and illustrating the inaccuracy in eyewitness testimony.
Term
Depth Perception
Definition
The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance. Perception happens in the brain!
Term
Unconscious Inference
Definition
A process postulated by Hermann von Helmholtz to explain certain perceptual phenomena such as size constancy. For example, an object is perceived to be at a certain distance and this is unconsciously taken into account in assessing its retinal image size, with the result that size constancy is maintained. See also size constancy.
Term
Difference Threshold
Definition
How much extra stimulus is needed to recognize a difference.
Term
Absolute Stimulus
Definition
How strong a stimulus must be to notice it outright.
Term
Working Memory
Definition
A newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory
