how does psychology relate to the level of the brain? (levels of analysis)

brain is the hard wire and the mental processes are the programs that run it

Wilhelm Wundt

What is a concept of Wilhelm Wundt's structuralism?

it was focused on that the mind could be broken down

looking within- technique of observing mental events as they occur.. not objectively verifiable.. limited access (excludes unconscious mind)

Who made psychology famous?

William James

where mental illnesses came from. one of the most difficult theories of psychology. the mind has separate behaviors: conscious and unconscious

What is the UNCONSCIOUS? (in the Psychodynamic theory)

outside conscious awareness and not able to be brought into consciousness at will.

What is the theory of behaviorism entail?

Based on the idea that you can not study the unconsciousness

Who invented the theory of behaviorism?

John Watson

Who made the theory of behaviorism important?

B.F. Skinner

What did Watson propose as the basic goals of scientific theory?

1. the mind cannot be observed
2. behavior can be observed
3. science should study the observable

Who began animal research?

Skinner

What is S-R psychology?

behaviorism, the same theory applies (the idea that you can not study unconsciousness)

What is reinforcement?

any consequence of a given behavior (think B.F. Skinner)

What is Humanistic psychology?

emerged in 1950s based on belief that people have positive values, free will, and deep inner creativity. inspired by the positive psychology movement (human behavior is completely out of human control)

Who created the idea of Humanistic psychology?

Carl Rogers and Abraham Maslow

What is cognitive psychology?

the approach in psychology that attempts to characterize the mental events that allow information to be stored and operated on internally

What is cognitive neuroscience?

the approach in pyschology thatt blends cognitive psychology and neuroscience (the study of the brain) when attempting to specify how the brain gives rise to mental processes that store and process information

What is evolutionary psychology?

evolutionarily successful cognitive strategies and goals survived, these strategies remain today because they serve an adapt function

What is cultural universality?

insistences of the same practice mental processes occurring in all cultures around the world

language, belief, values, norms, and behaviors shared among members of a group and passed from one generation to the next

culture

at the end of the terminal, release chemicals into the space between neurons when the neuron has been triggered.

respond to input from sense organs transmits to brain and spinal cord

what are motor neurons?

sends signals to muscles to control movement

what are brain circuits?

sets of neurons that effect one another when one neuron in a circuit is triggered.

resting potential

at rest neurons maintain a negative charge

action potential

the shifting change in charge that mvoes down the axon

the all or none law:

it either fires or it doesn't (chemicals)

synapse-

when an axon of one neuron sends a signal to the dendrite of another neuron

synaptic cleft-

the gap between 2 neurons

Neurotransmitters-

chemicals that carry signals from the terminal buttons of the sending neuron across the synaptic cleft to the dendrite of the receiving neuron

vesicles-

sacs holding neurotransmitters

receptors-

specialized sites on the dendrites or cell bodies that respond to specific neurotransmitters

lock-and-key- system-

only certain neurotransmitters can activate certain receptors

Excitatory-

making the receiving neuron more likely to fire an action potential

Inhibitory-

making the receiving neuron less easily triggered

reuptake-

the excess neurotransmitter back into the vesicles of the sending neuron

Acetylcholine-

a neurotransmitter involved in a number of functions, including motor control and memory. Malfunctions liked alzheimer's disease

Dopamine-

a neurotransmitter that regulates motor behavior, motivation, and reward. Malfunctions linked to schizophrenia and Parkinson's disease

Serotonin-

a neurotransmitter involved in the regulation of sleep and wakefulness, inhibition, and mood. Malfunctions linked to depression

GABA (gamma-aminobutyric acid)-

the primary inhibitory neurotransmitter in the brain. Malfunctions liked to anxiety disorders

Endogenous cannnabinoids-

released by the RECIEVING neuron that influence the activity of SENDING neuron

agonist v. antagonists

mimic the effects of a neurotransmitter by activating by activating a particular type of receptor (LCD, COCAINE, METH)

vs.

block a particular receptor.

selective serotonin- reuptake inhibitors (SSRIs)-

block the re-uptake of the neurotransmitter serotonin

glial cells-

help in the care and feeding of neurons

Central Nervous System

The spinal cord and brain together

Peripheral Nervous System

Links the brains to the organs and muscles to the bodies

Autonomic Nervous System

Controls the smooth muscles in the body and some glandular functions

Sensory Somatic Nervous System (SSNS)

Neurons in our sensory organs that convey information to the brain

Sympathetic Nervous System

Readies an animal for an emergency.

Parasympathetic Nervous System

Counteracts sympathetic effects by decreasing heart rate, contracting pupils, increasing salivation massively

Spinal Cord

The flexible rope of nerves that runs inside the backbone

Reflexes

Automatic responses to an event

Pinkish gray surface on the brain

Cerebral Hemisphere

Each half of the brain is shaped like a sphere
