Exam 1 (Chapters 2-4) Flashcards
Define Basic Research
Studies designed to understand nature of human behavior
What is an example of basic research?
Why people may not help in a situation
Define Applied Research
Studies designed to solve social problems
What is a hypothesis?
Prediction of what will be found in study (must be testable)
Where do research ideas come from?
-Inspiration from previous research + theories
-personal Observations
Define Diffusion Responsibility
The more ppl are around, the less likely for sum1 to get help or help
What causes diffusion responsibility?
the thought that someone has alr gotten help and bc they don’t feel responsible
What are the three types of research methods?
-Observational
-Correlational
-Experimental
Define Observational Research
A study design/method where researcher observes ppl + systematically records measurements/impressions of their behavior
What are two types of observational research?
-Ethnography
-Archival Analysis
Define Ethnography
Method where researchers attempt to understand a group/culture by observing them from inside w/o imposing any notions
Define Archival Analysis
Form of observational research where researcher examines the accumulated documents/archives of culture (not observing real-time but studies records of ppl)
What are some examples of Archival Analysis?
-Diaries
-Novels
-Magazines
-Records/Documents
What are some limitations of the observational research method?
-Some behaviors/social situations are difficult to observe
-can’t predict/explain causes of behavior
Define Correlational Research
Study design/method where researcher systematically measures 2 or more variables + asses the relation btwn the variables
What are the 4 types of correlations?
-Positive
-Negative
-No
-Correlation Coefficient
Define Positive Correlations
Increase in 1 variable, causing the other variable to also increase
Define Negative Correlations
Increases in one variable, while the other goes down
Define No Correlation
No relation btwn two variables (no Pattern)
Define Correlation Coefficient
Statistical technique that assess how well you can predict one variable from another (coefficients range from -1.0 to 1.0)
Define Survey
Research in which a representation sample of ppl are asked questions abt attitudes/behaviors (often anonymously)
what are some advantages of surveys?
-studies variables that are difficult to observe
-can sample representative segments of the population
Define Random Selection
Every one has the chance to be in the study (all population has an equal chance of being selected for a sample)
What are some disadvantages of Surveys?
-Sampling Errors
-Problems w/ accuracy on responses
What are limitations of correctional method?
Correlation does not = Causation
Define Experimental Research
Study design in which the researcher randomly assigns participants to diff. Conditions + ensures conditions are identical except for independent variable
Define an experiment
Researchers must have all following criteria in an experiment to manipulate a variable
Define Internal Validity
making sure nothing but independent variable affected dependent variable
How can one increase internal validity?
-Randomly assign ppl in different conditions
-Keeping everything the same
Define External Validity
Extended which results of study can be generalized to other situations + ppl
What are 2 types of generalizability?
-Across Situations
-Across People
Define Generalizability across situations
Extent to which we can generalize from the situation constructed by experiment to real life
Define Psychological Realism
Psychological process triggered in experiment are similar to psychological process that occur in everyday life
Define Generalization across people
Where we can generalize from ppl who participate in experiments to ppl in general
Define replication
Repeating study w/ different populations or different settings
Define Field Experiments
Conducted in natural settings rather than in a laboratory
Define informed consent
An agreement to participate in an experiment, granted in full awareness of nature of the experiment which they were explained in advance
Define Deception
Researches mislead participants abt the true purpose of a study or events that will transpire
