COUNTER CONDITIONING & DESENSITIZATION*
Counter conditioning means training an animal to display a behavior that is different than his current reaction to a stimulus.
_Desensitization_ is the process of exposing the animal to a stimulus beginning at a very low intensity.
_Counter conditioning and desensitization need to be used together_ to be effective and are often used to change unwanted behavior in dogs and cats, especially fearful and aggressive behaviors, for example: a dog that lunges at a person walking by is displaying an emotional response of fear or anxiety.
_Classical_ counter-conditioning would be accomplished by pairing the sight, sounds and approach of the delivery person with one of the dog’s favored rewards to change the emotional state to one that is calm and positive. Similarly for cats that are anxious or fearful when exposed to a visitor or other cat in the home, we would want to pair the cats favored rewards with the presence of the visitor or other cat.
A critical element of success is to prevent any exposure that might lead to a negative outcome during training. For dogs, this might be accomplished by recognizing potential problems and using a sit and focus command, a turn around or maintaining a relaxed walk past the stimulus.
_How to create a counter conditioning and desensitization program_
Go slowly!
Ideally, the program should be designed and carried out in such small steps that the problem behavior never occurs during the program. This means that all the stimuli that cause the behavior should be identified and that you should find a way to lower their intensity until your pet doesn’t react to them. For example, if a cat becomes afraid if someone approaches closer than six feet, then the starting point would need to be much further away than six feet.
Determine what is provoking your pet's reaction:!
For example, if a cat is afraid of being picked up, you would want to figure out exactly what she's scared of. Is she more afraid of adults than children? More afraid of men than women? More afraid of a family member or someone she doesn’t know?
Some common factors to consider include:
1. location,
2. loudness, distance,
3. speed of movement, length of time near the other animal or person,
4. response of the other animal or person,
5. and body postures of the animal or person who induces fear or aggression.
Arrange these characteristics in order from least to most likely to produce a negative response:
A counter conditioning and desensitization program needs to begin by using combinations of stimuli that are least likely to cause a fearful reaction. In the cat example above, perhaps the cat is least afraid of being handled by a familiar adult female who approaches slowly and speaks softly to her, while she’s lying on the bed in the bedroom.
She is most afraid of a person who runs up to her yelling while she’s in the kitchen.
Begin with the characteristics that are least likely to elicit the problem behavior:!
Begin with the easiest combination of characteristics of the situation, and gradually work up to the most difficult. If a cat will be less afraid of a male child approaching slowly than an adult female approaching fast, then we know SPEED OF APPROACH is more critical than type of person.
Don’t make all dimensions more intense at the same time.!
Devise ways to make each characteristic less intense:
If a dog is afraid of the sound of the hair dryer, the sound must be presented to the dog at a low intensity that doesn't provoke the fearful behavior. This could be done by turning the dryer on and off quickly before the dog shows fear, turning the hair dryer on in another room, covering the dryer with towels, etc.
Pair each level of each characteristic with a positive consequence:
Help your pet associate good things with the situation rather than bad things. Good choices are food (especially favorite treats), toys, and social reinforcements like petting, attention, and praise. If food is used it should be in very small pieces and be highly desired by your pet (cheese, hot dogs or canned tuna often work well). You may need to experiment a little to see what food is the best motivator for your pet.
Don't move on to the next level until your pet is clearly anticipating the reinforcement:
People commonly want to know how long they need to repeat each intensity level. This will depend entirely on your pet, who should be demonstrating that he is indeed expecting good things to happen. Perhaps he looks to you for a treat, or looks around for his toy. This should be in contrast to his previous reactions such as trembling, tensing up or other fearful or aggressive responses.
Progress slowly:
/Counter conditioning and desensitization/ take time and should be done very gradually.
Think through the steps you need to take.
Rather than expecting progress in leaps and bounds, look for small, incremental _change_. It can be very helpful to keep a record of your results, since day to day changes will not be very big.
You may need to supplement the behavior modification program with other approaches, such as avoiding situations that provoke the problem, using a headcollar like the Gentle Leader collar or treating your DOG with _anti-anxiety medication._ Your veterinarian or an animal behaviorist can give you more information on these options.
What is *DESENSITIZATION”
Desensitization is the gradual exposure to situations or stimuli that would bring on the undesirable behavior, but at a level so low that there is no negative response. As the animal experiences the stimulus but does not respond in the undesirable way, the animal becomes “/less reactive/” to the stimulus, and the dog can soon /tolerate/ a somewhat more intense stimulus without exhibiting the /undesirable response./
The key to effective desensitization:
is to first find the threshold at which the pet first responds by designing a stimulus gradient (from low responses to high responses) so that the pet can be gradually exposed to progressively more intense levels of the stimulus without the undesirable behavior being elicited.
Again, it is essential that the threshold not be surpassed unless the pet can be effectively calmed and settled.
* _What is “response substitution”?
/Response substitution/:
is a technique in which an undesirable behavioral response to a stimulus or situation is changed to one that is desirable. The goal is to _reinforce_ only those responses that are _desirable_.
Reinforcement of a response that is incompatible with the _undesirable_ response might be referred to as _differential reinforcement of an incompatible response_
The challenge is to get the desired behavior when exposing the pet to the stimulus, while also getting the appropriate relaxed and happy emotional state.
A number of /techniques/ can be used to help the owner turn the inappropriate response into one that is desirable. If the pet is trained through _reward based techniques_ to immediately focus on the owners in response to commands (settle, watch) in the absence of any distracting or fear eliciting stimuli, the training might then progress (through desensitization techniques) to gradually more intense levels of the stimulus.
Alternatively, lure and target training or _disruptive devices_ might be used to help more quickly and effectively _achieve the desired outcome._
For most dogs, a head collar and leash is the safest, most _effective_ and most _immediate_ method to obtain the _desired response_ (e.g., sit, focus, or heel).
In addition to the use of _positive reinforcement_, an immediate release of leash tension for each successful outcome also serves to _reinforce_ the _behavior_.
This is known as _negative reinforcement_ because the /behavior is being *reinforced* by *removal* of pressure and tension./
Regardless of the technique used, if the pet can be taught to _display_ a new _acceptable_ response instead of the _undesirable response_ when exposed to a stimulus then *response substitution* has been achieved.
Rather than attempting to overcome an intense response, the training should be set up to expose the pet with stimuli of /gradually increasing intensity/ (controlled exposure) to ensure a successful outcome. ****
By working with a gradient and favored rewards_, you may also be simultaneously /counter-conditioning/ the pet. However, when working with _fear and anxiety,_ the training is *not complete* if you merely get the _desired behavioral_ outcome.
A positive emotional state (relaxed, eating treats) must also be achieved using counter-conditioning.
For _*counter-conditioning and response substitution*_ to be most effective.
