Intro 3 levels of investigation - Answer- Description, prediction, and control Description - Answer- Collection of observations and facts which examines other possible relations and leads to a hypothesis Prediction - Answer- Repeated observations revealing relationships between events Control - Answer- Highest level of understanding; determines functional relations Experiment - Answer- Controlled comparison of some measure of the phenomena of interest under 2 or more different conditions in which one factor at a time differs from one condition to another External validity - Answer- Results can be generalized to other subjects, settings, or behaviors Internal validity - Answer- Assures that measured changes in behaviors are due to manipulation and not due to uncontrolled variables Qualitative research - Answer- Narrated with interviews and individualized accounts of events Group Design Research - Answer- one group gets the intervention, one group is the control (no intervention); uses stats; compares between groups single subject design - Answer- a research design that requires only one or a few subjects in order to conduct an entire experiment Causation - Answer- Something always happens because of something else Correlation - Answer- Variables are consistently present to a certain degree and something happens Functional relation - Answer- Occurs when it is highly unlikely anything other than the intervention caused a change in something Four main sections of research articles - Answer- 1.

Demonstration 2. Comparison 3. Parametric 4. Component Demonstration questions - Answer- demonstrated the existence of a functional relation Comparison questions - Answer- Two or more independent variables are studied in relation to a fixed set of dependent variables Parametric questions - Answer- Asks what effect incremental increases in the level of the independent variable will have on the dependent variable Measurement - Answer- Process of applying quantitative labels to observe properties of events using a standard set of rules Continuous measurement - Answer- Count, celeration, duration, latency, interresponse time, and permanent product Discontinuous measurement - Answer- Percentage, partial interval, whole interval, momentary time sampling, PLACHECK, and trials to criterion Validity - Answer- Directly measures a socially significant behavior as it pertains to the question Accuracy - Answer- Observed value matches the true value Reliability - Answer- Same values across repeated measurement of the same event Artifact - Answer- Something that appears to exist based on how it was measured Types of IOA calculation - Answer- Total count, mean count per interval, exact count, trial-by-trial, total duration, mean duration per occurrence, interval-by-interval, scored interval, and unscored interval Total count IOA - Answer- Comparison of two totals from each observer; smaller count divided by the larger count x 100 Mean count per interval IOA - Answer- Average taken from each interval and compared Exact count IOA - Answer- Each interval must match to score; # of intervals with 100% agreement divided by the total number of intervals Trial-by-trial IOA - Answer- Number of trials in agreement divided
