Unit 0: Scientific Foundations of Psychology Flashcards
Explain how psychology is a science.
Psychology is a science because it follows the scientific process just like normal science, meaning they have to come up with an experiment, hypothesis, conclusion, etc
Describe the three key elements of the scientific attitude
The 3 elements of scientific attitude are humility, curiosity, and skepticism
What is Critical Thinking?
Taking the information given and using different processes in order to process that information, meaning to question, analyze, describe, etc in order to better understand that information
Hindsight bias
When people feel that the answer was obvious after being given the answer
Confirmation Bias
When people only search for info that would further enhance their own belief instead of searching for conflicting beliefs
Overconfidence
people trust in their own abilities more than they should
Peer reviewers
people that review a study afterwards to see if it is sound
Hypothesis
If/then statement to explain the relationship between variables
Falsifiable
the ability to be proven false
Operational Definition
to make an experiment repeatable for the sake of being reliable
Replication
an experiment is repeated to see if the results can be repeated
Case Study
detailed study on 1 group or individual
Meta-Analysis
taking multiple experiments and combining them for a more generalized conclusion
Naturalistic Observation
observing something without interfering
Survey
quick questions about a topic that is usually cheap and garners al ot of answers
Social desirability bias
desire to answer what the researcher wants
Self-report bias
answers that deviate from the truth
Experimenter Bias
intentional or unintentional manipulation of the experiment to get desired results
Population
group that is getting conclusions drawn
Sample: specific group to collect data from
Sampling Bias
participants not being random and belonging to a certain group that makes the experiment not general
Random Sample
taking random people from the population
Convenience Sampling
taking people based on availability
Representative Sample
sample that is representative of the entire population or of a certain group
Experimental Methodology
systematic procedures and steps followed in a research study
Non-Experimental Methodology
research procedure that does not include the manipulation of a variable
Likert Scales
rating scale used to measure opinions, attitude, motivations, etc
Institutional Review
process where an institutions reviews the experiment and things related to it to see if it is ethical
Informed Consent
giving the participant enough knowledge of the experiment to give consent on whether to participate
Informed Assent
same as informed consent but with minors
Protect from Harm
protection of the participant form psychical and psychological harm
Confidentiality
keeping participant info secret
Research Confederates
people involved with the experiments participating in it to cause a certain event to occur
Measure of Central Tendency
tendency to gravitate to the center or average of the data
Measures of Variation
how far the values in the dataset are from each other
What are the 4 science practices that all students should develop?
Concept application, research methods & designs, data interpretation, and argumentation
What are the 4 basic ethical principles?
Informed consent
protection from harm
confidential info
debrief
Descriptive Stats
Numerical data used to measure and describe the characteristics of groups
mode
most frequently occurng score
mean
average
median
middle score in a distribution
percentile rank
Percentage of scores that are lower than a given score
skewed
Representation of scores that lack symmetry around their average value
range
Gap between lowest and highest
Standard deviation
Measure of how much scores vary around the mean score
normal curve
bell-curve that describes the distribution of data. Most scores fall near the mean, about 68% fall within 1 standard deviation of it
Inferential statstics
Numerical data that allows one to generalize the probability of something being true of a population
Statistically significant
How likely it is that a result occurred by chance
effect size
Strength of the relationship between 2 variables, the larger it is, the more 1 variable can be explained by the other
