n. 1. a form of nonassociative learning in which an organism becomes more responsive to most stimuli after being exposed to unusually strong or painful stimulation. 2. the increased effectiveness of an eliciting stimulus as a function of its repeated presentation.
What is an example of sensitization in psychology?
One simple example of sensitization is that school children are frequently sensitized to the sound of a ringing bell when they are waiting for the end of the school day. You may experience cognitive sensitization when you are waiting for your cell phone to ring when you know someone important is about to call.
Why is sensitization important in psychology?
Sensitization is a useful model in studying the underlying causes of pathologies such as asthma, substance dependence, allergies, pain-related illnesses, psychological disorders, etc.
What is the difference between sensitization and habituation?
Sensitization is the opposite of habituation. While habituation is a decrease in reactivity to a stimulus after repeated presentations of that stimulus, sensitization is the opposite—increased reactivity to a stimulus after repeated stimulus presentations (Cevik, 2014).

What are the 2 types of sensitization?
In summary, polysensitization can be divided into (i) cross-reactivity/cross-sensitization (the same IgE binds to several different allergens with common structural features) and (ii) co-sensitization (the simultaneous presence of different IgEs that bind to allergens that may not necessarily have common structural
What is sensitization and desensitization?
Abstract. Repeated application of capsaicin at a 1-min interstimulus interval (ISI) to the tongue induces a progressively increasing irritant sensation (sensitization), followed after a rest period by reduced sensitivity to further capsaicin (desensitization).
What is an example of a habituation?
For example, a new sound in your environment, such as a new ringtone, may initially draw your attention or even be distracting. Over time, as you become accustomed to this sound, you pay less attention to it and your response will diminish. This diminished response is habituation.
What’s the difference between habituation and sensitization and why do both make evolutionary sense?
The main difference between habituation and sensitization is that habituation is a decrease in an innate response to a frequently repeated stimulus, whereas sensitization is the increased reaction to a stimulus after repeated exposure.
What is the difference between sensitization and tolerance?
In the context of the study of drugs, tolerance refers to the decreased effectiveness of a given drug with repeated administration; sensitization to the increased effectiveness with repeated administration.
What is an example of sensitization in animals?
If the dog started salivating to the ticking of a metronome just because it had recently received food, rather than because the delivery of food had been signaled by the metronome, this should be regarded as an instance of sensitization rather than associative learning.
What is sensitization in the brain?
Abstract. Sensitization is defined as a non-associative learning process occurring when repeated administrations of a stimulus result in a progressive amplification of a response (Shettleworth, 2010).
What causes sensitization?
Central sensitization involves specific changes to the nervous system. Changes in the dorsal horn of the spinal cord and in the brain occur, particularly at the cellular level, such as at receptor sites. As stated above, it has long been known that strokes and spinal cord injuries can cause central sensitization.
What are the characteristics of sensitization?
Sensitization can cause abnormally increased responses to stimuli other than pain. This potentially includes increased sensitivity to chemicals (odors, medications), temperature, sound, weather characteristics and emotional stressors.
How do you test for sensitization?
Skin sensitization testing is traditionally performed using either human tests such as the human repeat insult patch test and the human maximization test or animal tests such as the murine local lymph node assay (LLNA), the guinea pig maximization test, and the Buehler test (OECD 1992; OECD 2010a).
What is sensitization and how do you prevent it?
Sensitization happens when a stainless steel is held at a temperature of 425 – 815°C and chromium carbides precipitate at the grain boundaries.
Sensitization can be prevented by:
- Reducing the carbon content.
- Adding stabilizers such as niobium or titanium.
- Reducing the time of exposure to the critical temperature range.
What are sensitization activities?
A sensitization activity or campaign may target an entire community at once, or sub- groups to engage separately. In certain contexts, it may be good practice to involve authorities and community leaders in developing the key messages and in implementing sensitization activities.
What is the goal of sensitization?
Sensitization literally means making people ‘sensitive’ about an issue. This is the core of awareness raising and is what you ideally want to achieve, that people become aware and react to certain issues.
What is a sensitization reaction?
Sensitization is a process by which the immune system will produce an antibody, which is a defensive protein, in response to a substance—such as certain foods, pollen, mold, or medications. 2 As such, allergy symptoms develop due to the reaction triggered by the immune system in response to the allergen.
Can you become sensitized?
This process is called sensitization. You’re sensitized when you have specific IgE antibodies in your blood. Once you have been sensitized to a particular allergen, your body will produce IgE every time you encounter that allergen again.
What happens during the Sensitisation phase?
Many cell-mediated immune responses appear to develop in two phases: A sensitization phase in which unprimed or memory T cells interact with dendritic cells to become active lymphoblasts, and an effector phase in which the T lymphoblasts and other presenting cells interact to eliminate the antigen.
