Habituation refers to the gradual reduction in the amount of Attention paid to a stimulus when it is presented several times.


In psychology, "habituation" refers to a decrease in responsiveness to a stimulus after repeated or prolonged exposure. It is a basic form of learning that involves the organism becoming accustomed to a stimulus that is presented repeatedly, leading to a reduction in the intensity or frequency of the response. Habituation is a pervasive phenomenon observed across various species and developmental stages, from simple organisms to complex human behavior. It serves as a fundamental adaptive mechanism, allowing organisms to filter out irrelevant or non-threatening stimuli from their environment, conserve energy, and allocate attention to more salient stimuli. Habituation is influenced by factors such as stimulus characteristics, intensity, duration, and novelty, as well as individual differences in sensory processing and cognitive processing.

Application Areas

  • Sensory processing research
  • Cognitive psychology
  • Behavioral therapy
  • Animal behavior studies
  • Developmental psychology
  • Attentional processes research

Treatment and Risks

  • Treatment: Habituation techniques are often utilized in behavioral therapy to help individuals overcome phobias, anxieties, or aversions by gradually exposing them to the feared stimulus in a controlled manner. Systematic desensitization and exposure therapy are examples of therapeutic approaches that rely on habituation principles to reduce fear and avoidance behaviors.
  • Risks: Habituation can lead to habituation effects, where individuals become desensitized to stimuli that are initially relevant or important. This may result in decreased sensitivity to genuine threats or decreased motivation to attend to important information in the environment.


  • A baby initially startles at the sound of a loud noise but gradually becomes less reactive to it after repeated exposure.
  • A person living near a busy street may habituate to the noise of traffic, eventually not noticing it anymore.
  • In behavioral therapy, a person with a fear of heights gradually habituates to the fear-inducing stimulus by exposing themselves to heights in a controlled and systematic way.

Similar Concepts and Synonyms

  • Adaptation
  • Sensory habituation
  • Response decrement
  • Acclimatization
  • Tolerance

In psychology, habituation refers to the decrease in responsiveness to a stimulus after repeated or prolonged exposure. It is a fundamental form of learning observed across various species and developmental stages, allowing organisms to filter out irrelevant stimuli and allocate attention to more salient ones. Habituation has applications in sensory processing research, cognitive psychology, behavioral therapy, and animal behavior studies. While habituation can be beneficial, leading to adaptive responses, it also carries risks such as habituation effects, where individuals become desensitized to important stimuli in their environment.
