Exam #1 Study Guide Flashcards
ABC Triad
Affect (how people feel inside), Behavior (what people do), Cognition (what people think about)
What is the difference between applied research and basic research?
Applied research focuses on solving particular problems, while basic research focuses on a general understanding of basic principles.
What is the difference between between-subjects design and within-subjects design?
Between-subjects design means participants are only exposed to one level of the independent variable, while within-subjects design means all participants are exposed to all levels of the independent variable
Confederate
A person secretly working for the researcher
Confounding Variables
Occurs when two of the effects of variables cannot be separated
What is the difference between construct validity and convergent validity?
Construct validity refers to the degree to which a test designed to measure a construct is actually measuring that construct, while convergent validity refers to the degree to which the results correlate with similar other measures.
What is the difference and what are the defining aspects of experimental approaches and correlational approaches?
Experimental approaches need control and random assignment, they are studies in which a researcher manipulates an IV and randomly assigns people to levels of it.
A correlational approach is a non-experimental method in which the researcher merely observes whether variables are associated or related
Correlation Coefficient (r)
The statistical relationship or association between two variables
Demand Characteristics
Any clues in a study that suggest to participants what the researchers hypothesis is
Dr. Gian is conducting an experiment to determine if meditation before bed would cause people to get better sleep, what is his hypothesis, dependent variable, and independent variable?
Hypothesis: meditation helps sleep
DV: quality of sleep
IV: meditation before bed
What are the five basic steps of the scientific method?
- Stating a problem to study
- Formulate a testable hypothesis
- Design a study
- Test the hypothesis against collected data
- Report study results
What is the difference between reliability and validity? Internal validity and external validity?
Reliability: the extent to which the a measure gives consistent results
Validity: refers to how much a measure measures what it purports to measure. Internal validity: the extent to which changes in the IV caused changes in the DV
External validity: how much a study’s findings can be generalized to other people and settings.
What is a factorial experiment design, and what are it’s main effects and interaction effects?
Factorial design: when there is more than one independent variable
Main effects: effects of a single variable while ignoring the effects of other variables Interaction effects: the effects of more than one variable acting together on the DV.
What is a field experiment? Quasi-experiment?
Field experiment: An experiment conducted in a real-world setting
Quasi-experiment: A study where the researcher can manipulate an IV but cannot randomly assign conditions.
What is an operational definition? (be able to give an example)
Operational definition: A description of something in terms of operations (procedures, actions, processes) by which it could be measured or observed.
Example: activation of the sympathetic nervous system as a operational definition of anxiety
What is the importance of random assignment?
It spreads out the effects of other variables that cannot be controlled, therefore improving internal validity; as well as helping to eliminate possible sources of bias
What role does mutation play in reproduction and survival according to Darwin’s theory of evolution?
Mutation is new genes or combinations of genes, if the mutation is helpful, it will improve reproduction and survival and will therefore help a species to evolve
Psyche
A broader term for mind, encompassing emotions, desires, perceptions, and all other psychological processes
What is special about humans in comparison to other social animals?
Our capacity for culture sets humans apart from other animals, unlike other animals humans use culture everyday and we depend on it for our survival
What was the main characteristic that related to brain size in various animals (social brain theory)?
Robin Dunbar found that bigger brains were mainly linked to having larger and more complex social groups
What is an example of culture influencing development?
Professional athletes are more likely to be born in January, due to the cut of date they are usually the biggest fastest kids and are therefore more likely to succeed, persist, and get attention from coaches
What is the duplex mind and what are its characteristics?
Duplex mind: the mind has two different processing systems (deliberate and automatic)
Automatic: Outside of consciousness, performs simple operations, operates always, even during sleep
Deliberate: Conscious mind (turns off during sleep), performs complex operations, sometimes may need to override automatic system
