PSCL 101 - Test 2 Flashcards
heuristic
mental shortcut to make decision quickly
naturalistic observation
the act of watching objects naturally behave in their environment without trying to manipulate the situation
external validity
refers to how well the result of a study can be generalized to other settings
internal validity
refers to how accurate the result of a study resemble the actual situation in the real world
Case - Study Research
the type of research that examines a small group of individuals over a long period of time
Correlational Research
the type of research that study the relationship between two variables
negative correlation
when we say that two variables have a negative correlation with each other, it means that when one variable increase, the other decrease and vice versa
positive correlation
when we say that two variables have a positive correlation with each other, it means that when one variable increase, the other also increase and vice versa
zero correlation
when we say that two variables have a zero correlation with each other, it means that there is no relationship between of the change of a variable to the other
causal relationship
when we say that a variable has a causal relationship with another variable, it means that the change of one variable will cause the other variable to change
limit of correlational - designed research
its outcome cannot conclude whether two variables have a causal relationship or not
You are an above average student and typically get very good grades. Someone asks you how you maintain such good grades and you reply: “I study a lot”. The connection between studying and GPA shows a ___________ correlation.
positive
Dr. Tau is interested in examining whether there is a
link between a large social support network and the
well-being of parents who have a child who has been
recently diagnosed with autism. What kind of
research method should Dr. Tau use to answer his
research question?
Correlational
Anna is a research assistant who is interested in
examining the gender roles in a rare Mexican tribe.
She moved to Mexico and joins the tribe in attempts
to answer her research question. What kind of
research methods id Anna employing?
Naturalistic Observation
Experimental Research
The type of research where one variable is manipulated to examine the second variable’s change
independent variable
the variable that is being manipulated
dependent variable
the variable that is being examined
Experimental group
the group that receive the same manipulation as the independent variable
Control group
a group that is being compared to the experimental group; it doesn’t receive manipulation, or receive the one that is not related to the experiment group’s one
a TRUE Experiment requires two important things:
- Manipulation of the independent variable
2. Random assignment of participants to be manipulated
random selection
a procedure in a research to make sure that every person in the sample has an equal chance of
being selected
In an experiment investigating the efficacy of an anti -anxiety medication, you give one group .5 mg of the

a placebo (sugar pill). The drug in this experiment is
the ___________ variable
independent
reliability
the stability or consistency of something
validity
the degree to which a tool measures what it claims to measure
external validity
the degree to which the result of a study can be generalized for conditions outside the laboratory
internal validity
the degree to how confident we are to draw a cause - effect relationship from a result of a study
memory illusion
refers to the phenomenon where you wrongly remember the detail of something, but the wrong thing that you remember is very compelling to you
eyewitness testimony
refers to the story of a person who saw the actual event of an incident
flashbulb memory
an accurate and long-lasting memory about a traumatic event
multi-stage memory model
a model that analyze different stages of information processing: encoding, storing, retrieving
next - in - line effect
an effect that talks about human forgetting information or events right before or after their turn of performance
mnemonics
a system of studying to improve recall ability
storage
the process of storing information into the memory
schema
a collection of past knowledge that is stored in the memory that help us decide how we should behave in a certain situation
retrieval
the act of recalling previous information that is stored in the memory
tip - of - the - tongue phenomenon
a phenomenon in which a person cannot recall a word but can recall the partial definition of it
three system of memory
sensory memory, short - term memory, long - term memory
sensory memory
a memory that stored information briefly before it is passed to the short - term memory
short-term memory
memory that retains information for limited durations
a way to aid short-term memory
chunking the amount of information you have to learn into meaningful chunks
