Memory


Encoding
* The process of information into the memory

Storage
* the retention of encoded material over time.
* pressing Crtl S and saving info

Retrieval
* Process of getting the information out of memory storage

Recall v. Recognition
*with recall - you must retrive the information from your memory (fill in the blank test)
*with recognition- you must identify the target from possible targets (multiple-choice test)

Flashbulb Memory
* A clear moment of an emotionally significant moment or event

Types of Memory
* Sensory Memory
* Short term memory

Sensory Memory
*immediate, initial recording of sensory information in the memory system
* stored just for an instant and most gets unprocessed

Short term Memory
* memory that holds a few items breifly
* seven digits (plus of minus two)
*the info will be stored into longer term or forgotten.

Working memory
*antoher way of describing the use of short term is called working memory
* working- memory has three parts
1. Audio
2. Visual
3. Integration of audio and visual (controls where you attention lies)

Long Term Memory
* the relatively permanent and limitless storehouse of the memory system

Automatoc Processing
*unconscious encoding of incidental information
* you encode space, tome and word meaning withour effort
* things can become automatic with practice

Effortful Processing
*Encoding that requires attention and conscious effort
*Rehearsal is the most common effortful processing technique
* Through enough rehearsal, what was effortful become automatic

Next in line effect
* we seldom remember what the person has just said or done if we are next

Spacing effect
* we encode better when we study or practice over times
* DO NOT CRAM!!

Serial Postioning effect
* Our tendency to recall best the last and first items in a list.

Types of encoding
* semantic encoding : the encoding of meaning like the meaning of words

* acoustic encoding: the encoding of sound, especially the sounds of words

* visual encoding: the encoding of picture images

Tricks to Encode
* Use Imagery: mental pictures
Mnemonic Devices use Imagery. Like my "peg word" system or...

Chunking
* Organizing items into familiar manageable units

TYPES of LTM
* Explicit
(With conscious recall
* fact-gerneral knowledge
* Personally experienced events

Implicit
* with out concious recall
* skulls motor cognitive
*classical and operant conditioning effects

Types of Retrieval Failure
Proactive Interference
*the disruptive effect of prior learning on the recall of new information

Types of Retrieval failure
*Retroactive Interference
* The disruptive effect of new learning on the recall of old information.

Misinformation Effect
*incorporating misleading information into ones memory of an event

Sensation

Touch
* receptors located in our skin
* Gate Control Theory of Pain
* the spinal cord a neuralogical gate that blocks, pain signals, or allows them to pass on to the brain

Vestibular Sense
* tells us where our body is oriented in spac
*Our sense of balance

Kinesthetic Sense
* Tells us where our body parts are.
* Receptirs locate in our muscles and joints.

Perception
* the process or organizing and interpreting information, enabling us to recognize meaningful objects and events.

Gestalt Philosophy
* the whole is greater than the sum of its parts

Figure Ground Relationships
* The organization of the visual field into objects (figures)
That stand out from their surroundings

Grouping
* The perceptual tendency to organize stimuli into groups that we understand

Depth Perception
* the ability to see objects in three dimenstions although the images that strike the retina are two dimesional
* allows us to judge distance

*visual cliff

Binocular Cues
* Rentinal Disparity: a binocular cue for seeing depth
* the closer an object comes to you the greater the dispairty is between the two images

Transduction Continued

Order is Rods/Cones to Bipolar to Ganglion to Optic never

Paralle processong

Color vision
* Three types of cones
* red
*blue
*green
* these three types of cones can make millions of combinations of colors.
*most colorblind people simply lack cone receptor cells for one or more of these primary

Opponetnt-Process theory
*the sensory receptors
*red/green
*yellow/blue
*black/white
* if one color is stimulated

Hearing
*the height of wave gives us the amplitude of the sound
* the frequency of the wave gives us the pitch of the sound

The Ear

Transductions in the ear
* sound waves hit the eardrum
Then anvil then hammer then
Stirrup then oval window
* everything is just vibrating
* then the cochlea viberates
* the cochlea is lined with mucus called basilar membrane.
* in basilar membrane there are hair cells.
* when hair cells vibrate they turn vibrations into neural impilses which are called organ of Corti
* sent then to the thalamus up auditory nerve

Pitch theory
Place theory
* different hairs vibrate in the cochlea when there are different pitches.
*so some hair vibrate when they hear high pitches and other viberate when they hear low pitches.

Frequency Theory
* all the hairs vibrate but all different speeds.

Deafness
Conduction Deafness
* something goes wrong with the sound and the vibration on the way to the cochlea
* you can replace the bones or get hearing aid to help

Nerve (sensorineural) Deafness
* the hair cells in the cochlea get dammaged
* loud noises can cough this type of deafness
*NO WAY to replace the hairs
* cochlea implant is possible

Smell and Taste
* Sensory Interaction: the princeple that one sense may influence another.

Taste
* we have bumps on our tongue called papillae
* Taste buds are located on the papillae ( they are actually all over the mouth*
*sweet, salty, sour, and bitter, hot spicy,
*bitter
*sour
*salty
*sweet
UMAMI- flavorful, meaty, saviory taste pollo asido

Types of intelligence

Crystallized Intelligence
* Accumulated knowledge.
* Increases with age.
Fluid Intelligence
* Ability to solve problems quickly and think abstractly
* peaks in the 20's then decreases over time
Moral Development
* Three Stage Theory by Lawrence Kohlberg!!
Pre-Conventional Morality
* morality based on rewards and punishments
* if you were rewarded then it is OK.
* If you are punished, the act must be wrong.
Conventional Morality
*Look at morality based on how others see you
* if your peers, or society, thinks it is wrong, then so do you.
Post-Conventional Morality
* Based on self-defined ethical principles
* your own personal set of ethics.

Schemas


Schemas
* children view the world through schemas ( as do adults for the most part)
* schemas are ways we interpret the world around us
* it is basically what you picture in your head when you think of anything
Assimilation
* incorporating new experiences
Accommodation
* changing an existing schema to adopt to new information
Stages of cognitive development
* sensorimotor stage
0-2
* experiences the world through our senses
* do not have object permanence
Preoperational Stage
2-7
* have object permanence
* begin to use language to represent objects and ideas
* Egocentric: cannot look at the world through anyones eyes but their own.
Conservation
* conservation refers to the idea that a quantity remains the same despotr changes in appearance and Is part of logical thinking.
Concrete Operational Stage
* can demonstrate concept of conservation
* learn to logically
Formal Operational Stage
* abstract reasoning
*manipulate objects in our minds without seeing them
* hypothesis testing
* trial and Error
* metacognition
* not every adult gets to this stage
