1) Father of Modern psychology 2) Opened up the first lab dedicated to psychological studies 3) Believed psychologist should look into a persons consciousness 4) Started the school of "structuralism" in psychology 5) Measured a persons consciousness by measuring ones reaction time to a particular stimulus. This experiment was breaking news because it showed that psychologist could measure things such as a persons consciousness.
Father of modern psych.
Studied basics of the mind
A persons subjective experience of the world and the mind
The analysis of the basic elements that constitute the mind
William Wundt, Edward Titchener.
analysis of the basic elements that constitute the mind.
introspection. reaction time experiment. Element and consciousness. elemental sensations/feelings
the analysis of the basic elements that constitute the mind. involved breaking consciousness down into elemental sensations and feelings
The systematic examination by individuals of their own thoughts and feelings about specific sensory experiences
the subjective observation of one's own experience/thoughts/feelings
viewing a stimulus, then reconstructing sensations after.
the subjective observation of one's own experience.
thinking about our own emotions
1) Liked art, but went to medical school and taught at Harvard 2) Disagreed with wundt about being able to break down a persons consciousness into separate parts (introspection) 3) developed functionalism psychology
agreed with Wundt on introspection, but not breaking consciousness down to elements. functionalism- how mind works to adapt in natural environment, was inspired by charles darwin's Natural selection
First American psychologist-Functionalist
a school of psychology that focused on how our mental and behavioral processes function-how they enable us to adapt, survive, and flourish.
How does mind work, how does it change/adapt? Mind is a flow streaming, so breaking up the conscious is not effective (structuralism)
the study of the purpose mental processes serve in enabling people to adapt to their environment
The study of the function of the mind
1) Proposed that psychologist focus on studying behavior 2) believed behavior was influenced greatly by the environment 3) developed behaviorism
John B. Watson
Mind is a black box, you cannot study what is inside it, you can only study what people DO.

Father of Behaviorism. Little Albert.
an approach that advocates that psychologists restrict themselves to the scientific study of objectively observable behavior - "Stimulus-Response". "Study of directly observable events."
John Watson. then BF Skinner. objectively observe behavior. You can measure behavior. disagrees with introspection. (structuralism and functionalism) focus on what ppl DO not EXPERIENCE.
approach that advocates the psychologists should restrict themselves to the scientific study of objectively observable behavior
observable actions of human beings and nonhuman animals
Observable actions of humans and other nonhuman animals
Scientific study of behavior and its enviro. determinant
abnormal behavior is learned
1) helped to develop behaviorism even more 2) preformed the Skinner box test "a conditoning chanmber" 3) believed in operant conditioning 4) believed people could be controlled by just affecting their environment 5) thought a Utopian like society could be formed 6) people did not like he was taking away free will from humans
focused on consequences such as punishment and reinforcement using the Skinner Box
Behaviorism. Skinner box
What section of psychology dominated the field from 1930s-1950s?
Why did Behaviorism become less popular after the 1950s?
it ignored the mental processes (such as how children learn language) and the evolutionary history of the organisms it studied.
1) dealt with patients who had hysteria 2) used hypnosis to get people out of their hysteria 3) Believed that many peoples hysteria could be traced back to a disturbed childhood 4) discovered the unconsciousness of a person 5) developed Psychoanalytic theory
Founder of Psychoanalysis, focused on the unconscious mind
believed abnormal behavior was caused by unconscious feelings, thus the goal of psychotherapy was to make these conscious
the mental processes that operate below the level of conscious awareness
Freud, Psychoanalysis. Part of the mind the operates below/outside of the conscious yet influences our behaviors, feelings, and thoughts.

Looking at why certain behaviors exist through evolutionary adaptions. (whats the advantage of liking certain things)
John Garcia. also inspired by Darwin. This psych. explains mind and behavior in terms of the adpative value of abilities that are passed down from the past generations. Like how the rats that were born in the Lab are nauseated by the sewer smell because their past ancestors can detect that.

Goals of psychological research
ask people to answer written questions

Case studies (case method)
A method of gathering scientific knowledge by studying a single individual
1) using senses to learn about events/object
2) observations are made through measurements,
use of one or more senses to gather information
Measurement: defining and detecting
1) operational definition: a description of a property in concrete measurable terms
2) Empirical method: are a set of rules and techniques for observation
Measures muscle contractions under a persons skin
A device that measures muscle contractions under the surface of a person's skin.
Measurement: Validity, reliability, and power
1) Validity: the extent to which a measurement and a property are conceptually related
2) Reliability: The tendency for a measure to produce the same measurement whenever it is used to measure the same thing
3) Power: The ability of a measure to detect the concrete conditions specified in the operational definition
Measurement: Demand characteristics
Are those aspects of an observational setting that cause people to behave as they think they should (Psychologist try to avoid this)
Measurement: Observer Bias
When the observers themselves are biased in their observation because they are specifically looking for what they ought to see, and not just what is really occurring. This is why observers themselves are often in the dark about the experiment.
descriptive statistics and inferential statistics
1. descriptive: statistical procedures used to summarize, organize, and simplify data
ex. mean, frequency
2. inferential: techniques that allow us to study a sample and then make generalizations about a population
ex. correlation, t-test
square root of the variance, of how much on avg the points differ from the mean
a statistic that describes the average difference between the measurements in a frequency distribution and the mean of that distribution
involves examining research data and results to determine what conclusions reasonably can be drawn to support or refute a stated hypothesis
A method of selecting a sample in which members are purposely selected to create a sample that represents the population on some characteristic(s) of interest.
the complete collection of participants who might possibly be measured
Entire group studied
A data collection technique that involves direct questioning of individuals about their behaviors and attitudes
Two variables are said "to be correlated" when variations in the value of one variable are synchronized with the variations in the value of the other
How are correlations found?
1) measure a pair of variables 2) Remeasure these pair of variables till you have a set of data 3) Try to discern a pattern in the series of measurements
Connection between two variables
What is the difference between a positive and a negative correlation
1) positive correlation: describes a "more-more" or "less-less" scenario
2) Negative correlation: describes a "more-less" or "less-more" term

What is a strong correlation?
What is a moderate correlation?

the most "accurate" way to represent a population. every person has an equal chance of being selected. still this could be skewed. but it doesn't matter
a technique for choosing participants that ensures that every member of a population has an equal chance of being included in the sample.
assigning research participants to groups by chance, thus minimizing pre-existing differences among the groups
helps us infer cause and effect. ex. splitting a group of kids that have married parents or a single parent into two groups. Random assignment makes sure that scientists don't put all kids with single parents in one room, unless that was done coincidentally by random assignment.
a procedure that uses a random event to assign people to the experimental or control group
the process of assigning subjects to experimental treatments randomly
What is the reason why we should rely on random sampling to make good inferences about populations?
1. Random sampling eliminates bias in the selection process of samples.
Why is the failure to sample randomly not always a problem?
sometimes similarity of a sample and a pop no matter - flyin pig
when ability to generalize an experimental result is important psychologists use same procedures on diff samoles
sumtimes similiarities of sample and pop is a reasonable assumption

Why is external validity not always important?
Because it is rare that a psychological study is trying to recreate a real world scenario

-neuron at rest
- (-70 mv)
-inside cell membrane has a negative charge (filled with K+ and negatively charged A- ions) while Na+ and Cl- ions are outside of the membrane

-brief change in electrical charge
-the cell is depolarized (inside becomes positively charged)
-The Action potential- the neuron fires
-all or non principle
What causes an action potential?
An all or nothing electric stimulation of the neuron shuts down the K+ channels & opens the Na+ channels, allowing Na+ to rush in and increase the positive charge inside the axon relative to the outside triggering the action potential.
How does the action potential get initiated?
A positive charge is created inside the axon by closing the potassium channels and opening the sodium channels
How is the action potential reversed?
A chemical pump shoots out the NA+ ions and brings in the K+ ions
Why is an action potential an all-or-nothing event?
If a stimulation is below the thresh hold of an action potential it will not go off and if it goes above (no matter how above it goes) the same action potential will be obtained
The time in which another action potential cannot occur because to many K+ are outside the axon and to many NA+ are inside the axon
