Psychological
Research
Psychologists study a wide
range of topics, such as language development in children and the effects of
sensory deprivation on behavior. They use scientifically testable models and
methods to conduct their research.
Describing
Research
Scientists use the
following terms to describe their research:
·
Variables: the events,
characteristics, behaviors, or conditions that researchers measure and study.
·
Subject or participant: an
individual person or animal a researcher studies.
·
Sample: a collection of
subjects researchers study. Researchers use samples because they cannot study
the entire population.
·
Population: the collection of
people or animals from which researchers draw a sample. Researchers study the
sample and generalize their results to the population.
The
Purpose of Research
Psychologists have three
main goals when doing research:
·
To find ways to measure and describe behavior
·
To understand why, when, and how events occur
·
To apply this knowledge to solving real-world
problems
