54
New cards
Multiple Stimulus w/ replacement (MS) Preference Assessment
Measures frequency in which a toy is chosen by replacing the toys in which the client did NOT choose

If client chooses toy 1 out of 3, replace toy 2 and 3 and repeat

If using MS with replacement, after the student selects an item, place that item back into the array.

If the student continues to pick the same item, do another session using MS without replacement so you can rank order the remaining items.

“Train and hope” refers to teaching individuals a desired skill within a treatment session and hoping that the individual will generalize the use of that skill without implementation of a predetermined plan or strategy to facilitate generalization.
74
New cards
Generalization
A skills is considered generalized when it occurs across various settings, people and stimuli, as well as overtime

Involves systematic planning
75
New cards

Skinner Box
behavior that is followed by pleasant consequences is likely to be repeated, and behavior followed by unpleasant consequences is less likely to be repeated
83
New cards
Skinner Box - Reflexive Motivation
Worsening set of circumstances

Instructors and demands can become the reflexive MO's-, indicating a painful or undesirable is about to occur

BTs should reduce value of escape and engage with child. Pair yourself with "good" things and make activities more fun than stopping them

Reflexive MOs- : Tone indicated a shock was coming for rats in experiment
84

Social (attention, praise)
Activity (games, movies)
Generalized Sr - money, credit cards, tokens
Back-up Sr - What is received after exchanging generalized sr (tokens)
86

Establish yourself as a reinforcer
88
New cards
Freebies
Providing reinforcement that child likes without conditions or demands

non-contingent
89
New cards
Steps to Establish Yourself as a Reinforcer
1. Pairing yourself with positive reinforcement (sanitize environment, don't give free access to preferred items, conduct preference assessments, give freebies at a high rate)

2. Assess if pairing procedure worked (Do they look forward to seeing you? Frequently walk or turn away to see if they want your attention)

3. Introduction of demands: If... Then (First few demands introduced will teach child to request for item or be simple/mastered demands)
90
New cards
Operant Conditioning
the modification of behavior via reinforcement and punishment
91
New cards
Stimulus-Stimulus Pairing
How to develop secondary reinforcers

Neutral stimulus (doesn't affect bx) is paired with primary or learned reinforcer. over time, neutral stimulus acquires reinforcing properties

Food + therapist saying "good job" -> client learns "good job" accompanies good things
92
New cards
