Habituation: Studying Infants Before They Can Talk
0 Views •
2023
Source: Laboratories of Nicholaus Noles, Judith Danovitch, and Cara Cashon—University of Louisville Infants are one of the purest sources of information about human thinking and learning, because they’ve had very few life experiences. Thus, researchers are interested in gathering data from infants, but as participants in experimental research, they are a challenging group to study. Unlike older children and adults, young infants are unable to reliably speak, understand speech, or even move and...

Testing for Odor Discrimination and Habituation in Mice

This manuscript describes a protocol to examine the olfactory system of rodents. The olfactory habituation/dishabituation test will allow investigators to determine whether a mouse habituates to a repeatedly presented odor and whether the mouse demonstrates dishabituation when presented a novel odor.

Habituation and Positive Reinforcement for Rodent Handling
0 Views •
2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Habituation and positive reinforcement are refinement strategies that help reduce stress during routine handling and experimental procedures in rodents. These approaches improve animal welfare, encourage voluntary cooperation,...

Habituation and Prepulse Inhibition of Acoustic Startle in Rodents

Habituation and prepulse inhibition of startle are operational measures of sensory gating. Sensory gating is disrupted in schizophrenia, and some other mental disorders and neurodegenerative diseases. We here describe a standard protocol to assess short-term and long-term habituation as well as prepulse inhibition of acoustic startle responses in rats and mice.

Methods to record auditory P50 sensory gating, a physiological marker of cerebral inhibition which reflects early stages of attention, are described.
FAQs
Repeated presentations shift the infant’s measured response over time, allowing researchers to track how attention changes within a session. Looking time, sucking, or heart rate can decline as the same event becomes familiar. This response pattern provides an observable index of early learning and processing without requiring spoken reports or deliberate task performance.
Dishabituation strengthens the interpretation that an infant noticed a difference between stimuli. After attention declines for the repeated event, renewed looking, sucking, or heart-rate change when a novel event appears suggests discrimination. Researchers can therefore examine not only reduced responding to familiarity, but also whether the infant detects a meaningful change.
Researchers can present visual, auditory, or tactile events and select a response that can be observed in infants, such as looking time, sucking, or heart rate. Matching the stimulus with an appropriate measure helps capture changes in attention or processing. This flexibility allows the same general approach to examine faces, patterns, sounds, and events.
The procedure relies on spontaneous behavior rather than verbal answers or compliance with explicit instructions. Infants can therefore participate before they speak or understand task directions. Their changing visual, sucking, or physiological responses give psychologists a way to study early attention, memory, perception, and learning at a pre-verbal stage of development.
A typical sequence begins with repeated presentations of one visual, auditory, or tactile stimulus while researchers record a measurable response. They look for a decline in behaviors such as looking time, sucking, or heart rate. A novel stimulus may then be introduced; renewed attention provides evidence that the infant detected a difference from the repeated event.
These tasks can examine how babies process faces, patterns, sounds, and other events before they can describe their experiences. Researchers use response changes to investigate early attention, memory, perceptual development, and learning. Comparisons among infants can also reveal individual differences in early processing, making habituation relevant to developmental psychology.
Infants do not all show identical response patterns when they encounter repeated or novel stimuli. Measuring the decline in responding and the reaction to novelty gives researchers observable data for comparing early learning and processing across individuals. Such comparisons extend habituation research beyond group averages and help characterize variation in cognitive development during infancy.
