What is the difference between a stimulus and a discriminative stimulus? A stimulus is a person, place or thing in someone’s sense receptors while a discriminative stimulus is a stimulus in the
presence
of which a response will be reinforced.
What is the difference between stimulus control and discriminative stimulus?
Psychologists say an operant behavior is under stimulus control if it is triggered (or suppressed) by certain stimuli. Because
an organism must discriminate between controlling stimuli to respond
appropriately, they are called discriminative stimuli.
What is a discriminative stimulus?
The discriminative stimulus is
the cue (stimulus) that is present when the behavior is reinforced
. The animal learns to exhibit the behavior in the presence of the discriminative stimulus.
What is a discriminative stimulus give an example?
A discriminative stimulus is the antecedent stimulus that has stimulus control over behavior because the behavior was reliably reinforced in the presence of that stimulus in the past. … In the example above,
the grandma
is the discriminative stimulus for the behavior of asking for candy.
What is a discriminative stimulus give an example quizlet?
An event or stimulus that precedes an operant and sets the occasion for an increase in operant behavior. … Examples of a discriminative stimulus:
Green Light, Open Sign
, etc. • A stimulus that sets the occasion for a decrease in operant responses.
How do you explain a stimulus control?
“Stimulus control is a term used to describe
situations in which a behavior is triggered by the presence or absence of some stimulus
. For example, if you always eat when you watch TV, your eating behavior is controlled by the stimulus of watching TV.
What is a stimulus in behavior?
Stimuli are
events in the environment that influence behavior
. A single stimulus can serve many different functions. Listed below are several functions that a stimulus can serve. … An observing response is sometimes necessary for presentation of the discriminative stimulus/stimuli.
How do you establish a stimulus control?
Reinforcement and extinction of behaviors
are the fundamentals in creating stimulus control. When the stimulus is present, the desired behavior is reinforced. When the stimulus is absent, the behavior is ignored or put on extinction.
How can you avoid a bad stimulus control?
To avoid establishing faulty stimulus control for auditory stimuli, instructors should
use a consistent pitch for all stimuli
and avoid exaggerating or elongating the pronunciation of parts of the auditory instruction without a specific plan in place for fading the stimulus features (i.e., within-stimulus fading …
What happens when a discriminative stimulus is present?
The presence of a discriminative stimulus causes
a behavior to occur
. Stimulus discrimination training may also occur with punishment. A behavior is less likely to occur in the presence of the SD. … A behavior is more likely to occur in the presence of the S-Delta.
What is a stimulus class in ABA?
aba #appliedbehavioranalysis. A stimulus class is
a group of stimuli that share either formal (physical), temporal (when they occur with respect to a response)
, or functional (effect on behavior) properties.
What is a stimulus change in ABA?
A “stimulus” is
an energy change that affects an organism through its receptor cells
. An example of this might be when a baby crawls into a room and sees a shiny object, such as a toy. In this case, the toy is the stimulus.
What will happen if the CS is presented many times in the absence of the US?
If the CS continues to occur in the absence of the US,
the CR eventually decreases in intensity and stops
. After a period of respondent extinction, in which the CS is repeatedly resented in the absence of the US, the CS does not elicit the CR. However if the CS is presented at a later time, the CR might occur again.
How do you know when operant stimulus control has been achieved?
Operant stimulus control has been achieved when:
A response occurs more frequently in the presence of a specific stimulus
, but rarely occurs in the absence of the stimulus. Stimulus generalization has occurred when: The same response occurs in the presence of two different, but similar, stimuli.
What is stimulus equivalence?
Stimulus equivalence is
a concept in Applied Behavior Analysis (ABA) that explains how relations can be formed among stimuli
. … The property of transitivity involves training two stimuli individually with a third and the learner recognizing that the two individually-trained stimuli also have a relation.
What is a stimulus Delta?
• Stimulus Delta (SΔ) Definition
– The stimulus delta is defined as ‘
a stimulus in the presence of which a particular response will not be reinforced’
(Malott, 2007, p. 202).
