Chapter 10 Flashcards
(26 cards)
Concept
A class of stimuli that have characteristics in common
Stimulus overselectivity
Students may respond either to some totally irreverent stimulus or only to one aspect of the stimulus
Concept
A class of stimuli that have characteristics in common
prompt
an additional stimulus that increases the probability that an SD will accasion the desired response
Modeling
“Watch me, I’ll show you.” Use of instruction through observation
Physical guidance
When students fail to respond to less stringent forms of prompting they may be physically prompted
fading
Gradual removal of prompts
decreasing assistance
the teacher begins with a level of prompting that virtually assures that the studennt will produce the appropriate response. Amount of assistance is then systematically reduced as the student becomes more competent
Errorless learning
When systematic alteration of the discriminative stimulus is the primary form of prompting
graduated guidance
used to fade physical prompts. Begins with as much physical assistance as necessary and gradually reduces pressure.
time delay
the form of the prompt itself is not changed, just the timimg
increasing assistance
the system of least prompts. The teacher moves to the least intrusive prompt in her repertoire and gives students an opportunity to respond. Reverse application of decreasing assistance
chaining
the instructional procedure of reinforcing individual responses occurring in sequence to form a complex behavior
shaping
differential reinforcement of successive approximations to a specified target behavior
terminal behavior
the desired goal of the intervention. A behavior that is not currently in the students’ repertoire
Initial behavior
a behavior that resembles the terminal behavior along some significant dimension and that is in the students’ repertoire
intermediate behavior
represents successive approximations toward the terminal behavior
What is the purpose of establishing simple discrimination?
To have the student differentiate something such as his name from other things that are not his name. Teachers want students to learn many things that involve multipe simple discriminations.
Why is it necessary to fade prompts?
Because you want the student to get to a point where students are able to complete the task on their own.
Function of task analysis
to pinpoint the terminal behavior and list necessary prerequisite skills and component skills in sequence. forms the basis of many of the teaching strategies used to teach individuals with disabilities to perform complex behaviors
Backward chaining
components to the chair are acquired in reverse order. Last component is taught first, other components are added one at a time.
forward chaining
teacher starts with the first link in the chain, teaches it until it is mastered, and then goes to the next link.
Types of prompts
Gestural prompts, verbal prompts, visual prompts, modeling, physical prompts
Setting Events
May be environmental, physiological, or social. May also be manipulated to bring about desired change in behavior.
