background image Psychology Test 1 Study Guide Psychology Psychology is the study of mental activity and behavior. The first psychology lab was in 1879 Structuralism: belief that conscious experience can be 
broken down into components
Functionalism: belief that the mind helps humans adapt to 
environmental demands
Scientific inquiry is when psychologists study the what, why, 
and when of behavior and mental processes
Scientific inquiry utilizes the scientific method. The 3 essential elements are theory, hypothesis, and 
research.
-Theory: interconnected ideas and concepts that explain
what is observed and makes predictions about the 
future
-Hypothesis: specific prediction of what should be 
observed in the world if a theory is correct
-Research: conduct, analyze
Good theories -It is falsifiable
There are many hypotheses that are testable
-Simple
Research -Conduct the study
-Analyze the data
-Report the results
       Incorrect solutions are the result of noncritical thinking -ignoring evidence
-misunderstanding or not using statistics
-seeing relationships that do not exist
-using relative comparisons
-accepting after-the-class explanations
-taking mental shortcuts
-failing to see our own inadequacies (self-serving bias)
-failing to accurately judge source credibility
Neurons
background image Basic units of the nervous system Three basic phases -Reception
-Integration
-Transmission
Three types of neurons -Sensory: detect info from the physical world and pass 
along that info to the brain
-somatosensory nerves: provide info from the skin and 
muscle -Motor: directs muscles to contract or relax, movement
-Interneurons: communicate within a local or short-
distance circuits Dendrite: branchlike extensions; gets the information and 
passes to cell body
Cell Body: information is collected and passed to axon Axon: information is transmitted to other neurons Glial: non-neuronal cells that maintain homeostasis Myelin Sheath: insulates some axons to allow for faster 
movement along the axis
Node of Ranvier: small gaps of exposed axon; charging 
station
Terminal Buttons: at the end of axons; small nodules that 
release chemical signals from the neuron into the synapse
Synapse: gap between the terminal button and the next 
neuron
Neurotransmitters: chemicals that transmits from one 
neuron to another
Resting membrane potential: electrical charge of a neuron 
when inactive
-Ready for action: negative of inside and positive on 
outside
Action potential (neural firing): electrical signal that passes 
along the axon and causes release of chemicals from 
terminal buttons
Neurotransmitters receive chemical signals from nearby 
neurons at the dendrites
