 Antecedents 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 (covert)  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 D  Discriminative stimuli (S )—a direct antecedent to the behaviors. discriminative stimuli (stimuli) + behave (triggers the bevior)  associated consequence (operant conditioning).  Motivating operations--it makes a consequence more effective or increase the likelihood of doing the behavior. You’re really motivated by that behavior.  Discriminative stimuli  A cue that sets the occasion for a particular behavior and consequence Δ  Other stimuli serve as an antecedent for not doing a behavior (S ). a trigger of something not happening.  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 ringsdiscriminative 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 the behavior.  Stimulus generalization  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 shakingthese 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.  Stimulus control  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 controlled.  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 )  Attention  Noticeable: eg. Alarm clock, if you didn’t get up, you might wanna make the clock louder, more noticeable.  Understandable  Prompting  Reminds you or helps you to perform a behavior  Response prompts: Supplement the discriminative stimulus
