Blueprint Half Length: P/S Flashcards
independent variable
the variable the is being controlled and altered to see how it affects another variable
dependent variable
the variable that we are observing to see how it is affected by the independent variable
confounding variable
a variable that influences both the dependent variable and independent variable
makes the 2 variables seem related when they are not
mediating variable
explains why two things are related
the independent variable leads to the mediating variable which leads to th independent variable
moderating variable
a variable that affects the strength of the relationship between the independent and dependent variable
five main ways to increase the power of an experiment/study
- increase the alpha level
- decrease random error
- conduct a one-tailed test
- expand the sample size
- increase the effect size
alpha / significance level
the probability of rejecting the null hypothesis when it is actually true
random error
error that occurs due to chance
there is always some variability when a measurement is made
may be caused by slight fluctuations in an instrument, the environment, or the way a measurement is read, that do not cause the same error every time
effect size
tells you how meaningful the relationship between variables or the difference between groups is
one-tailed vs two-tailed effect
one-tailed: a directional hypothesis, points to what direction the effect will appear in
two-tailed: predicts that the independent variable will have an effect on the dependent variable, but the direction of the effect is not specified
list the types of social support (5)
emotional
esteem
informational
tangible/instrumental
companionship
companionship support
the type of support that gives someone a sense of social belonging
emotional support
the actions that people take that make us feel loved and cared for; involves listening and empathizing

support in the form of financial assistance, material goods, or services (ex. help with childcare, offering a ride, bringing dinner when you are sick, etc)

implicit bias
when we have attitudes towards people or associate stereotypes with them without our conscious knowledge
confirmation bias
the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one’s prior beliefs or values
acetylcholine
in PNS, voluntary muscle control and parasympathetic nervous system
in CNS, linked to attention and arousal/alertness
catecholamines
inclues epinephrine, norepinephrine, and dopamine
all play an important role in emotion
monoamines or biogenic amines
inclues epinephrine, norepinephrine, dopamine, AND serotonin; due to similarities in molecular composition
epinephrine and norepinephrine
both involved in controlling alertness and wakefulness
primary neurotransmitters of the sympathetic nervous system (fight-or-flight)
