Conducting Studies Part 1 continued and Part 2 Flashcards
Behavioural measure
some other aspect of participants’ behaviour is observed and recorded.
Ceiling effect
Clustering of scores at the high end of a measurement scale
Demand characteristics
-any of the potential cues or features of a study that suggest to the participants the purpose and hypothesis of the study, and influence the participants to respond or behave in a certain way
Double-blind procedure
Neither the experimenter nor the participants know in what condition participants are in
Experimenter bias
Measurements are influenced by the experimenter’s expectations regarding the outcome of the study
Filler items
the participants do not get the full purpose of the study when giving them the survey
Floor effect
Clustering of scores at the low end of a measurement scale
Manipulation check
-Measures that try to directly assess whether the manipulation had the intended effect
* If used, manipulation checks are typically included at the end of the experiment (after the DV has been measured
Advantages of manipulation check
- Identify required strength of the manipulation by conducting a pilot study
-Helps interpret the results of the study
Manipulation strength
Physiological measure
measurement of body temperature with a clinical thermometer, or they may be more complicated, for example measuring how well the heart is functioning by taking an ECG
Pilot study
allows the research team to gain experience and training, which can be particularly beneficial if new experimental techniques or procedures are used
Placebo group
response to a treatment that has no real effect on the body but the participant thinks its effective
Self-report measure
method to measure emotions and are based on participants’ self-reported (perceived) experience of emotions, rather than behavioural or physiological emotional information
Sensitivity
the perception of sensory input from the environment such as sound, smell, taste, and touch
