RM - everything Flashcards
Types of Experiments: Definitions (LAB)
- high level of control over variables (DV/IV)
- using standardised procedures
- Manipulation of IV
Types of Experiments: Eval good (LAB)
- cause / effect established
- high internal validity
- easily replicated / can be reliable
Types of Experiments: Eval Bad (LAB)
- no ecological validity / lower external validity
- lack mundane realism
- Demand characteristics - pps know
Types of Experiments: Definitions (FIELD)
- less artificial environment
- natural behaviour
- IV changed
Types of Experiments: Eval Good (FIELD)
- pps act normal / higher ecological validity
- more mundane realism
- less DC
Types of Experiments: Eval Bad (FIELD)
- EV may influence / confound DV data
- cannot randomly allocate - pps variables (indi diff)
Types of Experiments: Definitions (Natural)
- naturally occurring change of IV with DV measured
- other variables cannot be controlled
Types of Experiments: Eval Good (Natural)
- research avoiding ethical issues
- no DC - high external validity
Types of Experiments: Eval Bad (Natural)
- many EV / no cause and effect
- no replication / cannot make reliable.
Types of Experiments: Definitions (Quasi)
- no allocation of IV measurement
- IV = innate to pps / gender / age
Types of Experiments: Eval Good (Quasi)
only way of studying innate characteristics
Types of Experiments: Eval Bad (Quasi)
- may be other variables contributing to effect on DV = confounding
what are the 4 types of experiments
- Lab
- Field
- Natural
- Quasi
What are the types of observation
- naturalistic / controlled
- participant / non- participant
- covert / overt
observation definition
non experimental research - record behaviours - no manipulation of IV
Observation: Definition (Controlled)
environment controlled - pps same experience
Observation: Eval Good (Controlled)
- control limits EV
- standardised = reliable
Observation: Eval Bad (Controlled)
- contrived environment = less external validity
Observation: Definition (Naturalistic)
- real environment observation
Observation: Eval Good (Naturalistic)
- higher external validity
- more generalisable
Observation: Eval Bad (Naturalistic)
- EV = lower internal validity
Observation: Definitions (Overt)
- pps aware of observation
