|
Non-Experiments (Ethnographic studies) |
Research practices that do not involve the direct control or manipulation of independent and dependent variables. Ex: a case study involving written observations of a participant or by the participant in terms of natural situations and experiences |
|
|
"Real Experiments" |
Research protocols and procedures that require design planning and decisions regarding the control and manipulation of independent and dependent variables e.g., experimental treatments or tasks performance measures, quantitative analysis, interpretations |
|
|
Quasi Experiments |
Research protocols and procedures that require design planning and decisions regarding the control and manipulationof independent and dependent variables, but are semi-restricted in being able to assign participants randomly to various experimental conditions |
|
|
Positive Correlation |
Increases in one variable are associated with significant increases in a second variable |
|
|
Negative correlation |
Increases in one variable are associated with significant decreases in a second variable |
|
|
Longitudinal Study |
A study over a period of time that is enough to see change; subjects are measured repeatedly across essential age designations |
|
|
Cross-sectional study |
Experiment or observation that involved data collection from different-aged samples of subjects at one specific point in time; thus the comparison of performance at different ages is a function of the performance of different individuals at those ages |
|
|
Preference Procedures |
Research protocol ansering the question is A desired more than B? Ex: high amplitude sucking/suck rate, contingency learning, visual scanning |
|
|
Dicrimination Procedures |
Research protocol answering the question is A different than B? Important as a follow-up in a negative finding in a preference experient. That is, if the subject does not prefer A over B, can the subject discriminate them? Ex: habituation/dishabituation |
|
|
Psychophysiology (Heart Rate change/EEG) |
Research measure of changes in the interheat interval of ongoing heart rate activity that correlates with various attention states Ex: the "orienting response" is typically seen as a sudden decrease in HW as the subject shifts attention to an event |
