OCD-obsessive behaviors that cause anxiety
Remember antecedents? (sometimes both overt and covert)
Overt ~. punching a wall. Sth that’s observable, outside can see.
Covert ~. sth only yourself can identify. In yourself. Antecedents to hand
washing—feeling anxious, feeling dirty.
Examples of behaviors – antecedents?
Eating lunch: see others eat(overt).feeling hungry(covert).
Smiling: feeling happy(covert antecedent)
Singing: antecedent—hearing a song (overt?)
Doing homework: you saw there’s homework(overt). You think you wanna do
Timing in antecedents
Immediate: the one that’s closest in time
Distant (looking at your schedule in the morning, plan for lunch in a couple hours)
Two types of antecedents
Discriminative stimuli (S )—a direct antecedent to the behaviors.
discriminative stimuli (stimuli) + behave (triggers the bevior) associated consequence
Motivating operations--it makes a consequence more effective or increase the likelihood
of doing the behavior. You’re really motivated by that behavior.
A cue that sets the occasion for a particular behavior and consequence
Other stimuli serve as an antecedent for not doing a behavior (S ). a trigger of something
Discriminative stimuli—antecedents. Comes before the behavior.
Discriminative—lead you to a specific behavior, not a bunch of other behaviors. Helps
you to discriminate things to do.
Examples: phone ringsdiscriminative stimulus
What can you do when phone rings? Pick it up. Click it off. Check voicemail. etc
OCD. Stimulus for hand washing: feeling anxious, touching sth think contaminated.
The most discriminative stimulus to hand washing? It’s frequently occurring, directly linked to
Attribute consequences of the discriminative stimulus to other similar stimuli
Examples: phone rings. You understand that there are other type of ringtones and phones
that you can answer in life since the first time picked up the phone as a kid. You
generalize the discriminative stimulus.
OCD—door knob, light switch, hand shakingthese things are all thought contaminated
coz generalized stimuli. Everybody touches those things. The touching stimulus is being
generalized. Linking to the discriminative stimuli so that we generalize.
The behavior tends to occur mainly in the presence of the cue and the occurrence of the
cue is present, the behavior is highly likely to occur. The stimulus is so linked to a
behavior that you start to do it automatically. You do it when you don’t even realize.
Example: How are you? fine, how are you.(even if you’re not fine.) so stimulus
Open your PC was going to do homework but end up with checking email and fb.how
did that happen automatically?stimulus control.
Sometimes we want to either increase or decrease the stimulus control.
Increase stimulus control- increases the power of the (s )
Noticeable: eg. Alarm clock, if you didn’t get up, you might wanna make the
clock louder, more noticeable.
Reminds you or helps you to perform a behavior
