Term
What is the scientific method as it is related to psychology?
Definition
The scientific method was developed at the beginning of the 17th century; first applied to physics, then biology. In psychology, the scientific method was used to understand human behavior.
Term
Can thoughts be measured?
Definition
No, thoughts are immeasurable.
Term
What are overt behaviors and what do they measure?
Definition
commonly behavior is referred to as "overt behavior" or "overt responding" ex)walking, talking, describing your dreams. MUST be measures based on occurrence of behavior and NEVER absence of behavior
Term
What is reactivity?
Definition
when the subject's behavior changed because they are -or they believe they are- being watched
Term
Why is randomization so important to the experimental method?
Definition
So that an experiment provides valid results for the cause of a certain result; by controlling variables there can't be another factor causing something to occur (like in correlational method where there can be an illusory correlation)
Term
What are independent and dependent variables?
Definition
Independent is the variable that the experimenter controls or manipulates. The dependent is the variable that the experimenter believes will be affected bu the independent variable. (dependent depends on independent)
Term
Give BRIEF description of Wundt:
Definition
developed the first psychology lab in Germany in 1879
Term
Give BRIEF description of B.F. Skinner:
Definition
expanded the philosophy of behavior(this was all that was in the auxiliary notes, going to look it up in the textbook)
Term

Definition
alertness
Term
What is the function of Thalamus?
Definition
central location of all sensory input
Term
What is the function of Limbic System?
Definition
controls emotion; ex) hormonal releases controlling sexual interest ex) interest and enjoyment of feeding ex)acquisition and retrieval of emotional memories
Term
What is the function of Reward Center?
Definition
located in the limbic system. Any behavior consequented with a reward will increase in frequency; ex)drug addiction ex)electrical stimulation of reward center ex) learned relations through social attention. Damage to this area or drugs used to reduce it's activity cause a reduction in pleasant emotions and a reduction in motivation.
Term
What is the function of Language Center?
Definition
90% of people have language located in the left temporal lobe
Term
What singular location are your memories located in?
Definition
association cortexes? on google it said in the cortex; also, There isn't a single exact location of memory storage. The process of encoding and retrieving memories
Term

Term
What two main categories is brain scan technologies separated into?
Definition
static(snapshot) and functional(across-time)
Term
Give a brief description and the category this falls into: CT
Definition
STATIC; computed tomography is a simulated 3-dimensional x-ray for your skull; it's useful for assessing the presence of skull fractures, bone chips, or other foreign matter in brain; it does little to asses the activity of brain tissue
Term
Give a brief description and the category this falls into: MRI
Definition
STATIC; magnetic resonance imaging passes a strong magnetic field through the subject and measures the changes in magnetism, changes are then used by a computer to generate a 3-dimensional image; useful for measuring static states such as brain damage(areas of dead brain tissue)
Term
Give a brief description and the category this falls into: EEG
Definition
FUNCTIONAL; the electroencephalogram is a measure of ELECTRICAL activity of the brain taken from the epidermis of the scalp; electrical activity of the brain passes residual signals through the skull and skin to electrodes pasted on the scalp; broad measures of activity; simply the general activity- this is the oldest and least valuable brain scan technology
Term
Give a brief description and the category this falls into: MEG
Definition
FUNCTIONAL; the magnetoencephalogram is a measure of the MAGNETIC changes in the brain; magnetic activity changes based on the amount of blood flow that occurs to a particular region; the MEG records the level of magnetic activity across the brain and superimposes its measures on an MRI taken from the same person
Term
Give a brief description and the category this falls into: PET
Definition
FUNCTIONAL; positron emission topography is a measure of GLUCOSE activity in the brain; radioactive glucose injected into patient; then the patient's given intellectual tests; the PET scan measures location of the radiation in the brain
Term
Give a brief description and the category this falls into: fMRI
Definition
FUNCTIONAL MRI; functional magnetic resonance imaging measures localized changes in magnetism as a result of blood flow through brain areas; as intellectual tasks are performed, there will be an increase in blood flow through the area(s) that control that behavior
Term

through their behavior and the way they handle things (ex. object permanence)
Term
What is stimulus habituation and how do you produce it?
Definition
eventually the subject becomes habituated to the stimulus and ignores it
Term
What is a novel stimulus and how do you react to it?
Definition
whenever something occurs that is novel to an organism, the individual stops what it is doing and turns its sensors to the source of stimulation
Term
What is habituation?
Definition
(sensory adaptation) is the process by which a repeatedly sensed stimulus elicits less reaction

0-2; learn through sensory interaction-develop object permanence
Term
Give time span and key characteristics for Preoperational Stage:
Definition
2-6; language development; use of symbols with little logical reasoning; pretend play begins; egocentricism(whenever they have a thought they thing everyone else has it) exists until a "theory of mind" develops
Term
Give time span and key characteristics for Concrete Operational Stage:

Definition
Term
Why is stranger anxiety and separation anxiety?
Definition
Term
When do stranger anxiety and separation anxiety develop and how are they related?
Definition
12 months and they're related because they're similar; stranger anxiety is when babies are afraid of strangers (usually people other than immediate family) and separation anxiety is when a baby enters a place (ex. daycare) with mom and then cries when mom leaves (thus, left w strangers)
Term

Definition
Term
What were some side effects of the experiment of the monkeys?
Definition
Term
Can the side effects of the monkey experiment be reversed? Why/Why not?
Definition
Term
What is critical period? What is it called in humans and why?
Definition
a period during which a particular form of learning must occur, or you will lose your chance to develop that skill. In humans, myelination is the time-flexible critical period.
Term
What does brain plasticity have to do with the critical period?
Definition
Brain plasticity just refers to when the brain is impressionable; the changing of neurons, the organization of their networks, and their function via new experiences. Brain plasticity has to do w the critical period because puberty begins a final period of brain myelination; brain undergoes a development of greater myelination that's correlated w the capacity to think abstractly
