Both ________ ___________and ___________ _____________share commitment to answering psychological questions with direct formal observations and to commute with others about their findings
research producers and research consumers
Why is the Research Producer role important?
- for coursework
- for graduate school
- for working in a lab

- for psych courses
- when reading articles based on research

What is empiricism (aka empirical methods/research)?
Idea that knowledge comes from observations
Skepticism
Philosophy that ideas must be evaluated on the basis of careful logic and results from scientific investigations
Empiricism uses what type of evidence?
Evidence through our senses
What are the parts (in order) of the theory data cycle?
- theory
- research question
- research design
- hypothesis
- data
What do researchers do in a theory data cycle?
scientists collect data to test, change, or update their theories
Main idea of the cupboard theory?
due to the mother being the main holder of resources for the infant , they cling to them - the mother is the "cupboard"
i.e - dog seeing owner
Main idea of the contact comfort theory?
Infant monkeys preferred the cloth mother (had food) compared to the wire mother (no food) - most infant monkeys preferred the cloth monkey
What does the theory-data cycle test for regarding good scientific theories?
- Is it falsifiable?
- Does it have parsimony?
- Does it prove anything?
What are the 3 different types of research?
- Basic Research
- Translational Research
- Applied Research
What is Applied Research?
research done with a practical problem in mind and the researchers conduct their work in a local, real-world context.
Provide an example of Applied Research.
might test the efficacy of a treatment for depression in a sample of trauma survivors
What is Basic Research?
enhance the general body of knowledge rather than to address a specific, practical problem
Provide an example of Basic Research
might want to understand the structure of the visual system, or the capacity of human memory, etc.
What is Translational Research?
the use of lessons from basic research to develop and test applications to health care, psychotherapy, or other forms of treatment and intervention
__________ research is the bridge between basic and applied research
translational
Provide an example of Translational Research
basic research on how mindfulness changes people's patterns of attention might be TRANSLATED into a study skills intervention.
What is a hypothesis?
A prediction stated in terms of the study design - the specific outcome the researcher will observe in a study if the theory is accurate.
What is a theory?
A set of statements that describe the general principles about how variables relate to one another
How do scientists share the results of their research with the scientific community?
Submitting to a scientific journal
What is Temporal Precedence (Think A comes before B)?
means that the method was designed so that the casual variable CLEARLY comes first in time before the effect variable..one of the causes of behavior under the goals of behavioral science.
What is Covariation of Cause and Effect?
Effect occurs ONLY in the presence of cause...one of the causes of behavior under the goals of behavioral science.
What is Elimination of Alternative Explanations?
Nothing other than a causal variable could be responsible for the observed effect....one of the causes of behavior under the goals of behavioral science.
What is the Research Question?
formulated as the first and most general step in the research process - must be specific so the project can answer it
Difference between Hypothesis and Prediction?
A hypothesis is a tentative answer to a research question and a prediction is a GUESS of the outcome of a study
Explain the comparisons of Research Vs. Experience
- experience has No comparison group and is confounded
- research is better and is probabilistic
Why are comparison groups important ?
They provide different data points but it's important to not have too many differences between the groups
At the end of the day, although experience is good...its ____________ in research.
Confounded! When you think you may understand why one thing caused an event, something else actually did.
What does the scientific approach do?
offers objective rules for learning about the world
Why is Research better then just trusting our 'intuition'
Intuition is biased!!
Name the 5 ways in which intuition is biased
1. Being swayed by a good story
2. availability heuristic
3. present bias
4. confirmation bias
5. blind spot
What is the Availability Heuristic?
Being persuaded by what easily comes to mind
What is present bias?
failing to think about what we cannot see - we fail to think about comparison groups
What is confirmation bias?
focusing on the evidence we like best "cherry picking" - usually favors your opinion or experience
What type of bias is the biggest in research?
confirmation bias
What is the blind spot bias?
biased about being biased. belief that we are not likely to fall prey to other biases. feeling as though biases dont apply to you.
Explain the factors of science vs. intuition
- we make mistakes when we base our reasoning on intuition rather than on science
- researcher create comparison groups and look at all the data

3. Casual
What is a frequency claim?
describes a particular rate or degree of a single variable -- involves only using ONE measured variable
