The body's information system is built from billions of interconnected cells called neurons.
Neaural Communication
Parts of the neuron.
Dendrites
Cell body
Axon
Melin sheath
Terminal branches
Synapse
A brief electrical charge that travels down an axon.
Action Potential
The space between the end of the axon of the sending neuron and the dendrite of the receiving neuron.
Synapse
(chemicals) releasted from the sending neuron travel across the synapse and to the receptor sites on the receiving neuron.
Neurotransmitters
The body's information system is built from billions of interconnected cells called neurons.
Neaural Communication
Process in the synapse where extra nerotransmitters are reabsorbed into the sending neurons.
Reuptake
Pathways are invovled with mood regulation
Serotonin
Pathways are invovled with diseases such as schizophrenia and Parkinson's disease.
Dopamine
Enables muscles activity and seem to be low for those with Alzheimer's disease.
Acetylcholine
Neurotransmitters related to pain and "good feelings" and pain relief.
Endorphins
Similar reaction, doesn't fit exactly.
Agonist
Inhibits, blocks action.
Antagonist
The body's slower communication system
The endocrine system
Chemicals sythesized by the endocrine glands that are secreted in the blood stream
Hormons
Secretes many different hormons, some of which affect other glands.
Pituitary gland
Affects metabolism, among other things
Thyroid gland
Helps regulate the level of calcium in the blood.
Parathyroids
Inner part called the medulla helps trigger the fight or flight respons
Adrenal Glands
Regulates the level of sugar in blood.
Pancreas.
We detect physical energy from the envioronment and convert into neutral signals.
Sensation
We select, organize and interpret our sensations.
Perception
This beins with sense receptors and works up to the level of the brain.
Bottom-Up Processing
Iformation processing guided by higher-level mental processes as we construct perceptions, drawing on our experience and expectations
Top-Down Processing
Minimum stimulation needed to dectect a particular stimuls fifty percent of the time.
Absolute Threshold
Minimum difference between two stimuli reqauired for detection fifty percent of the time.
Difference Threshold
Two stimuli differ by constant minimum percentage to be perceived as different.
Weber's Law
Transparent tissue where light enters the eye.
Cornea
Muscle that expands and contracts to change the size of the opening (pupil) for light.
Iris
Area that focusses on the light rays on the retina.
Lens
Contains sensory receptors taht process visula information and alerts the optic nerve
Retina
Area of the retina where the focus of the light ray produce the closest image
Fovea
nerve that transmits information from the retina the brain.
Optic Nerve
The process by which the lens changes shape to help focus near or far objects on the retina.
Accomidation
Irregular curvature of the cornea or lens.
Astigmatism
Is a degenitive disorder of the eye in which structural changes with in the cornea cause it to thin and change to a more conical shape that its normal gradual curve
Keratoconus
Darkening of lens--old age and UV radiation
Cataracts
Increase pressure in eye, because it's not being drained properly.
Glaucoma
Back of eye coming lose; causes you to lose use of retina
Retinal Detachment
Pieces of veteras that float around; unless you have a lot, nothing to worry about.
Floaters
Leading cause of blindness.
Age-Related Macular Degneeration
Optic nerves connect to the thalmus in the middle of the brain, and the thalmus contains the visual cortex.
Visual information processing
Nerve cells in teh visual cortect respond to specific features, such as edge, angles and movement
Feature Detection
Processing several aspects at the same time. The brain divides a visual scence into subdivisions such as; color, depth, form, movement, etc.
Parallel Processing
Mind to mind communication
telepathy
Perception of remote events, such as sensing a friends house on fire
Clairvoyance
Perceiving the future
Precognition
A relatively permanent change in an organism's behavior do to experience
Learning
Tw events occur together
Classical Conditioning
Response followed by consquence
Opperant Conditioning
Russian physiologis who eluciated classical conditioning.
Ivan Pavlov
The initial learning stage in classsical conditioning.
Acquisition
When US does not follow the CS, CR begins to decrease and eventuall causes extinction
Extinction
Tendency to respond to stimuli similar to the CS.
Generalization
Cosidered consciousness unimportatn for the scientific study of psychology.
Watson
Ealy behaviorists believed tht learned behaviors could be reduced to
mindless mechanisms
We learn to fear somethings easier than others.
Biological predisposition
Found that for cats rewarded behaviors were likely to occur again, and he called this law of effect.
Edward Thorndike.
Deserves credit for the discovery and understanding of operant condtioning type of learning
B.F Skinner
Box that comes witha bar or key that an animal manipulates to obtain a reinforcer liek food or water
Operant Chamber or Skinner Box
Any event that strengthens the behavior it follows.
Reinforcement
Add a deseirable stimuls
Positive Reinforcement
Remove an averse stimuls
Negative Reinforcement
And innately reinfocing stimulus like food or drink.
Primary Reinforcer
A learned reinforcer that gets is reinforcing power therough association with the primary reinforcer.
Secondary (Conditional) Reinforcer.
Reinforces the desired response each time it occurs.
Continuous Reinforcer
Reinforces the desired response only part of the time
Partial Reinforcement
Reinforces a response only after a specified number of responses
Fixed Ration Schedule
Reinforces a response after an unpredictable number of responses
Variable Ratio Schedule
Administer an averse stimulus
Positive Punishment
Withdraw a desireable stimuls
Negative Punishment
