Psych Exam 1 Flashcards
What is Psychology
The study of behavior and mind
Who viewed the world as a picture
John Locke
Who viewed the world as a painting
Emmanuel Kant
Whats Empiricism
Evidence thru observing
Whats Nativism
Innate Knowledge
When was the first lab
1897
Who is the father of Psych
William Wundt
Whats Structuralism
analyze mind by breaking
it down into basic parts, studied thru introspection
Whats functionalism
How mind processes info to help humans adapt
what you do not what your made of
Whos Sigmund Freed
Developed Psychoanalytic theory
Whats Psychoanalysis
Therapy aiming to provide insight into
contents of unconscious mind
Whats Behavioralism
suggests that psychologists should
only study objectively observable behavior
Gestalt
The whole is more than
the sum of its parts.
Social Psychology
deals with social interactions
Cognitive Psychology
scientific study of human
information processing, including perception, thought,
memory, and reasoning
Evolutionary psychology
studies how mind & behavior have
been shaped by natural selection
Cultural Psychology
studies how
cultures (values, traditions, &
beliefs) influence mental
processes of their members
Whats Rationalism
knowledge thru reason and argument
Scientific Method steps (there are 6)
- Identify Problem
- Gather info
- Hypothesis
- Design and conduct
- analyze
- restart
The 5 ethics principles
- Beneficence
- Fidelity & Responsibility
- Integrity
- Justice
- Respect for people’s rights
& dignity
Independent variable
The variable that is manipulated
Dependent Variable
Variable thats measures
Experimental vs controlled
ex: group that does experiment
cont: baseline measure
Types of measurement
Reliability: How consistent is measure
Validity: How accurate is measure
Power: Ability to detect differences in
variable being measured, when they exist
Internal Validity
How much did IV(s)
cause changes in DV(s)?
External Validity
How well do findings
generalize to real-world settings?
Scatterplots
visual representation of
relationship between variables
Linear + and -
Positive ~ as X scores increase, Y scores
also tend to increase
* Negative ~ as X scores increase, Y scores
tend to decrease
nonlinear
Curvilinear ~ as X scores increase, Y
scores alter direction after certain point in
relationship
* No relationship ~ X & Y scores do not
seem to move in same direction
Two Major Nervous System Divisions
Central (CNS)
Peripheral (PNS)
Central (CNS)
Brain and spinal cord
Peripheral (PNS)
Everything besides brain and spinal
Somatic nervous system (SNS)
Voluntary Movement
conveys information into & out of CNS
Autonomic nervous systems (ANS)
carries
involuntary & automatic commands that control
blood vessels, body organs, & glands
Divisions of Autonomic Nervous System (ANS)
sympathetic NS
Parasympathetic NS
Sympathetic NS
Fight or Flight
Parasympathetic NS
Relax and rest
Spinal Cord
transmit sensory information
to brain & to distribute motor information to
organs and muscles
Divisions of Brain
Hindbrain
Midbrain
Forebrain
Hindbrain
Controls basic life functions
Midbrain
Orientation and movement
Whats the highest level of the brain
Forebrain
Forebrain
cognitive, emotional, sensory, & motor functions
15
Hindbrain Parts (4)
Medulla
Reticular Formation
Pons
Cerebellum
Medulla
Survival Center (heart and lungs)
Reticular Formation
regulates arousal, sleep,
wakefulness, attention, & alertness
Pons
rea of info relay from
cerebellum to rest of brain
Cerebellum
Controls & coordinates fine
motor movements
Midbrain Parts (theres 2)
Tectum
Tegmentum
Tectum
Helps orient in environment
Tegmentum
movement and arousal
Parts of Forebrain (3)
Cerebral cortex
subcortical Structures
Corpus Callosum
Cerebral Cortex
Outermost brain layer divided into 2 hemispheres
Subcortical Structures
Housed under cerebral
cortex near brain’s center
Corpus Callosum
thick band of nerve
fibers connecting the 2 hemispheres (used to cut during strokes)
Limbic System (4)
Thalamus
Hypothalamus
Hippocampus
Amygdala
Thalamus
Relay station for sensory info (not smell)
Hypothalamus
keeps body balanced
Hippocampus
learning and memory
Amygdala
emotional
4 Lobes of Brain
Frontal
Temporal
Parietal
Occipital
Frontal Lobe
Movement, planning, memory, judgment, etc.
Pre-Frontal Cortex
complex decision-making
Brocas Area
Speech Production
Temporal Lobe
hearing and language
Parietal Lobe
Touch
Occipital Lobe
light and visual
Endocrine System
network of glands that produces &
secretes hormones into bloodstream
Whats the master gland
Pituitary gland
Pituitary gland
releases horomones
Control stress, digestive activities, & reproductive processes
Pineal gland
helps sleep
Cell
basic structural &
functional unit of life
forms.
carries out functions
Neurons
communicate with each other
Glial Cells
support cells
Neuroplasticity
ability of
neurons & their networks to
change
BRAIN PLASTICITY
Brains ability to change
Parts of a neuron
Dendrites
Soma
Axon
Nodes of Ranvier
Axon Terminals
Dendrites
receives info
from other neurons &
relays to soma
Soma
keeps cell alives, holds nucleus (DNA)
Axon
carries messages from soma to terminal
Nodes of Ranvier
gaps of myelin sheath
Myelin
fatty layer surrounding nerve cells, brain, and spinal cord
Axon terminals
releases neuron transmitters
Synapse
fluid-filled space between neurons
What is connected to the soma
dendrites
Conduction
Movement with neuron
Transmission
movement across synapse
Whats negative internal charge
-70 mV
Whats resting potential
difference in electric charge between inside and outside of neuron’s cell membrane
What stages are referred to as electrochemical action
transmission and conduction
Whats action potential
electric
signal conducted along neuron’s axon
