Ch. 1: The Science of Psychology Flashcards
What is science?
Science is a democratic cumulative field in which we employ the use of systematic observation to form a question stated in such a way that we can test it; e.g., a hypothesis
What are the different elements of the scientific method?
Acronym: ARCTADS
🔴 Ask a question 🟠 Do research 🟡 Construct a hypothesis 🟢 Test through an experiment 🔵 Analyze data 🟣 Determine alignment of data with hypothesis ⚪️ Share results
What is the research process in psychological science?
Acronym: IDACAP
🔴 Idea for a study 🟠 Design a study 🟡 Application to the IRB (institutional research board) 🟢 Collect data 🔵 Analyze data 🟣 Peter review & publication process
What are the specific goals of the field of psychology?
⚫️ To better understand ourselves and others
⚫️ To learn how to better help others and improve the world, for example, by doing effective psychotherapy
Define hypothesis.
A logical idea that can be tested
Define theory.
Groups of closely related phenomena and observations
What are the difference between a hypothesis and a theory?
A hypothesis is an assumption made before any data has been collected while a theory is a principle set to explain phenomena already supported by data
What are the 6 different research designs?
Acronym: eqqcls (pronounced: equals)
- Experimental
- Correlational
- Qualitative
- Quasi-experimental
- Longitudinal
- survey
What are the benefits and limitations of experimental research?
Benefits: random assignment; random assignment makes it so groups, on average, are similar on all characteristics except what the experimenter manipulates
Limitations: Subject to human error, sample may not be representative, and results may be difficult to replicate.
What are the benefits and limitations of an quasi-experimental designs?
Benefits: Allows you to conduct research on a subject matter that defies random assignment
Limitations: doesn’t allow for random assignment and therefore it would be hard to make causal inferences
What are the benefits and limitations of a qualitative design?
Benefits: Allow us to research more difficult topics, e.g., brain injuries
Limitations: The sample size is extremely limited, Personal experience and knowledge influence observations and conclusions. It is not statistically representative because it is based solely on observation rather than empirical data, and it’s difficult to investigate causality.
What are the benefits and limitations of a correlation all design?
Benefits: Allows us to study topics we can’t experimentally manipulate
Limitations: Can’t infer causation
What are the benefits and limitations of an longitudinal study?
Benefits: More precise results
Limitations: can be quite costly to conduct
What are the benefits and limitations of a survey?
Benefits: Can reach a larger number of participants
Limitations: May receive dishonest answers
