Chapter 14: Managing Antecedents
Identifying and Modifying Existing Antecedents:
1st step in managing antecedents = identify existing cues through f. assessment
Identifying Antecedents:
Hunches should not be conclusions
Antecedents for a behv specific to indiv
Need to assess the antecedents for e/ person
Ease which we can identify antecedents depends on whether they are over or covert and/or
immediate or distant AND excess or deficit
Antecedents for Behavioural Excess:
Behavioural excess antecedents that are overt and immediate fairly easy to identify
o Sometimes not easily noticed
Behv excess that are covert or distant more difficult to identify
o Some cases person isn’t even aware of the cues
o Use careful direct observations AND indirect assessment methods (interviews,
questionnaires)
Antecedents for Behavioural Deficits:
Behv deficits, identify cues that set occasion for a behv not occurring
Look for antecedents and conseqs linked to non-occurrences of responses
Ways to alter the antecedents:
Manipulating physical or social stimuli
4 basic ways:
o Dev or intro new Sds
o Modify existing Sds
o Manipulate Mo
o Manipulate effort needed to make response
Developing or introducing new Sds:
Teaching indivs Sds that they don’t already know
Provide conseqs (reinforcement) for a particular behv when a specific stim (Sd) is present but
not when some other stim (S-delta) is present
Time consuming process shortcut methods (physical guidance, instructions, transferring stim
cntrl)
o Ex: reduce tv watching, post sign on tv “Do not watch”
