Q

Systematic Replication

A

previous research replicated w/ some variation (researcher, populations, procedures)

  • demonstrate reliability of effect
  • extend generality of findings
  • identify exceptions

Q

Considerations when Choosing IVs

A

Is the process of implementing IV clearly described?

oUse treatment integrity measures to ensure proper use
•Is it appropriate to the consumer’s ability?

  • Are there risks?
  • Are you evaluating all IVs to the most appropriate standard of implementation?
  • Is the IV a package?

Q

Validity/ Accuracy

A

The extent to which data are relevant to DV and purpose for measurement (true measure)

oAre you collecting data on the correct behavior?

oMake sure you’re measuring the right dimension of behavior

–Target behavior: Aggression
»Intensity vs. frequency of occurrence

oMake sure you’re using the right type of measurement: –Target behavior: Tantrums

Does the IV cause the DV to change

Q

Threats to Internal Validity

A 
–Procedural fidelity/procedural drift
–Attrition/participant drop out
–Cyclical variability of the data
–Effects of testing
–Maturation of participants
–Reactivity

Q

Assessing Observer Reliability/IOA

A

“Establishing a criterion or criteria in a way that two or more observers can agree on their occurrences.”

Discrepancies in data collection:•Inadequacies of observers
•Inadequacies of observation code/definition •Inadequacies of calculation

Q

Interobserver Agreement (IOA)

A

Assesses whether data are reliable
•IOA validates your operational definition
Consideration: Identify ways to minimize observer bias

•Calculating IOA (TOTAL reliability):
L/H x 100 (frequency, duration, intensity, latency, permanent product)
L: Low
H: High

A/A+D x 100 (interval and time sample
A: Agreement–D: Disagreement

Q

Measurement Considerations

A 
•Minimizing Reactivity
Wait
Avoid interactions
Be out of the way
Minimize distractions
•Observer drift
•Selecting inappropriate measuremen
t•Inadequate operational definitions
•Not enough data

Q

Interval Based Rec

A 
Interval Recording•
Whole-interval recording
•Partial-interval recording
•Frequency-within-interval recording•
Continuous vs. discontinuous
  • Whole===If it occurs throughout the interval
  • Partial—-If it occurs at any point in the interval
17
Q

Time Based Measuring

A

Temporal Dimensions
Duration—Amount of time response is performed

Latency—–Amount of time between the onset of a stimulus and the behavior

Interresponse time (IRT)—-Amount of time that occurs between two consecutive instances of a response

18
Q

Event Rec

A 
Event Recording (frequency)
Pencil and paper•Clickers, counters•Pennies, etc.•Electronic data collector (iPhone app, etc.)•Calculating response rate•Total responses•Responses per minute
19
Q

Time Sampling

A
  • Time Sampling
  • Momentary Time-sampling
  • Observe whether a behavior occursat a specific time
  • Usually the end of an interval (But not always)
  • Removes need for continuous observation
20
Q

Social Validity

A

1) the extent to which the dependent variables are socially relevant
2) the intervention is socially acceptable
3) the results produce significant change

21
Q

Treatment Integrity

A

•Treatment Integrity- the accuracy of the implementation of an intervention
Assessment of treatment integrity is essential: To determine effectiveness of the intervention

22
Q

Produce High Treatment Integrity

A 
Operational definition
Simplify
Training 
Task analyses
Assessing
23
Q

Methods to Assess Treatment Integrity

A

Methods to assess treatment Integrity
•Checklists
•Direct observation

24
Q

Selecting a research question Consideratons

A
  • scholarly contribution
  • setting
  • participants
  • research assistants
  • equipment and materials
  • time frame
25
Q

4 components in a Research Proposal

A
  1. Abstract
  2. Introduction
  3. Method
  4. (hypothetical) results
26
Q

Bx Outcome Goals

A
  1. INCREASE OR DECREASE BEHAVIOR
  2. TEACH NEW BEHAVIOR
  3. GENERALIZE OR MAINTAIN BEHAVIOR CHANGE
27
Q

Dependent Variable Considerations

A
  • choosing based on previous data (previous data may have used subjective meas.)
  • previous research may have used objective meas., may have to modify or use measurement may modify to be specific to study
  • Incorrectly labeling or defining DV (DV should be defined in a way that 2 independent observers see the same bx and score the same occurrences/nonoccur.)
  • current rate of bx does not justify study (incorporate a control or baseline to determine extent or absence of prob to determine rationale for DV)
  • DV is not socially significant/face validity (part of your study’s intro/lit review will be to demonstrate that the current DV is socially significant, provide rationale for your study)
28
Q

Independent Variable Considerations

A
  • decription of variable should include all ASPECTS (technological)
  • collect data on the implementation of the intervention/IV
  • calculate treatment integrity
  • consumers (teacher, caregiver capability does user intervention have specific skill prior)
  • Risks? (effects on peers or non-target subjects, potential side effets, decreat 1 bx but increases another
  • Evaluating Non-behavioral procedures (don’t test straw man and avoid bias)
