Chapter 8: Antecedents: Stimulus Control
Antecedents: cues that precede and set the occasion for a behaviour (cause us to do, think, and
feel)
o Cues tell us what to respond by linking cues to behaviour and its consequence.
Behaviour happens in a context which includes objects, peoples, and internal events ex. hunger.
Anything in the context that arouses behaviour is a stimulus.
Example of antecedent influencing behaviour: a teacher asking a question sets the occasion for
students to raise their hands.
o Antecedents involve any of our senses
o Effects of antecedents may vary between people. Ex. not all students will raise their
hand.
Types of Antecedents:
Overt and Covert Antecedents
o Overt: open or directly observable through senses ex. seeing your dog
o Covert: internal and not open to observation ex. feeling tired
Ex. buying things compulsively is a negative reinforcement; it gets rid of
negative emotions of anger or depression.
Immediate and Distant Antecedents
o Immediate antecedents: are present shortly before the behaviour occurs.
Ex. putting out food in buffet style for elderly to increase their communication
with each other.
o Distant antecedents: precede behaviour by several minutes, hours, or much longer
amounts of time.
They affect behaviour for a long time after occurrence due to strong emotional
.and covert components.
Ex. a woman who is physically abused may go on for years with emotions and
thoughts about these events.
It is easier to identify antecedents that are overt and immediate rather than covert
and distant.
Antecedent functions:
Motivational function: relates thirst to water (behaviour to a consequence)
Discrimination function: seeing a water fountain (discriminating it from many other objects)
Discriminative stimulus (S): ex. reading a note and pressing the correct key on the piano. The note was
a stimulus. Ex. restroom picture displaying both genders can use the restroom.
Behaviour continues to occur if it was reinforced in the past or it occurs less frequently if it was
punished.
