Baseline Pre-intervention assessment that is used to refine recording procedures, design the intervention and provide data with which to compare intervention data when evaluating intervention effects.
Behavioral view of “sensory defensiveness” Tactile stimuli are negative reinforcers
Complete Behavioral Support Plan 4 Elements: motivational operations, discriminative control, replacement behaviors and consequence manipulations
Conditional probability The likelihood of an event occurring, given another event (e.g., how often a behavior occurs, given an antecedent). Formula: #A–> B/ # A OR # B –> C/# B.
Contextual Variables (setting events) Variables that are more generally present stimuli that are not necessarily manipulated as part of a behavior change program. May influence the efficacy of behavioral procedures. Ex: medical status, task variation, number of staff, etc.
Dependent Group Contingency Reinforcer for a group depends on the behavior of a single person or small # of people
Ecological Changes Changing schedules, staffing patterns, activities, diet, etc.
How to compute conditional probability of A-B sequences # A–>B / # A
How to compute conditional probability of B-C sequences # B–>C / # B
Interventions that follow from assessment Ecological changes, antecedent manipulation, replacement skills, change consequences of appropriate and inappropriate behaviors, emergency procedures, motivational operations
Lag 1 "Examines the liklihood that an event occurs given another event that occurs just before.Example: A –> B"
Lag 2 "Examines the liklihood that an event occurs given another event that occurs 2 events prior.Example: A2 –> A –> B"
Lag sequential analysis 'Computations that examine the liklihood that an event will occur given another event. It can be between an A and B, or between a B and C. Formula for A and B: Prob(A–>B)/Prob(A). Formula for B and C: Prob(B–>C)/Prob(B)
