Experiments
Description of how a variable is measured
Operational definition
Participants should not exposed to physical or psychological harm greater than what they might encounter in everyday life.
(Protection from) Undue Harm
The extent to which study findings can be generalized beyond the specific conditions of the experiment, such as different populations, settings, and times
External Validity
Capacity of STM?
7 (plus/minus 2)
Duration of sensory memory?
.25-.50 sec
The measured variable
Dependent Variable
Participants must be informed that they can stop participating at any time without penalty or negative consequences.
Right to withdraw
This occurs when selected participants are not representative of the target population
Selection Bias
Capacity of Long Term Memory
(Potentially) Unlimited
Which group in Glanzer and Cunitz (1966) struggled to remember the last few words in a list?
The group that had to count backwards for 30 sec.
Identify the IV:
A researcher wants to examine how caffeine use affects anxiety levels
caffeine use
Participants must be fully informed about the nature, purpose, and potential risks of the study before agreeing to participate
(Informed) Consent
The group that a psychologist is trying to draw a sample from is called:
Target Population
What must happen for information to be stored in Short Term Memory from Sensory?
Attention
Part of HM's brain that was removed
Hippocampus
A factor other than the independent variable that might produce an effect in an experiment
Confounding Variable
Participants' identities are not recorded or connected to their data, ensuring their privacy is protected.
Anonymity
When a sample is an accurate picture of the group you are trying to study it is:
Representative/Generalizable
The best way of prolonging the storage duration of information beyond its limit in short-term memory is through _________
Rehearsal
What is the function of the hippocampus?
Moving memories from STM to LTM / Creating new long-term memories
A researcher holds these constant in order to establish a cause and effect relationship between their IV and DV
Controlled Variables
After the study, participants must be fully informed about the true purpose, any deception used, and allowed to ask questions.
Debriefing
the extent to which a study can confidently demonstrate a cause-and-effect relationship between the independent variable and the dependent variable
Internal Validity
Memories of general facts/knowledge about the world
Semantic memories
Define Anterograde Amnesia
The inability to create new long-term memories
