Autism research

Autism spectrum disorder is defined entirely by behavior. There are no medical tests or biomarkers, so progress depends on what we can see, measure, and understand.

Noldus tools help researchers around the world capture those observations with precision and consistency. Whether studying children in a playroom, mice in a social test, or infants showing early signs of atypical development, our software turns complex behaviors into objective data.

Discover how Noldus empowers autism research through automation, accuracy, and insight.

The challenges of measuring autism

Autism affects social interaction, communication, and repetitive or restricted behaviors. Each person on the spectrum is unique, which makes objective measurement essential. Traditional observation methods rely on human judgment and can miss subtle patterns that carry important meaning.

Researchers studying autism face several key challenges:

Complex and variable symptoms

Autism influences multiple domains that can change across contexts and individuals.

Subjectivity in manual observation

Human coding and clinical ratings are prone to bias and inconsistency. Are there objective measures?

Limitations of using animal models

Animals do not express social behaviors in human ways, which can hinder translational outcomes.

The need for early detection and diagnosis

Most efforts to detect autism before the age of two rely on parental reports rather than infant behavior.

The Observer: Structured behavioral coding

The Observer for studying infant behavior

Social interaction, communication, and therapy sessions involve behaviors that must be coded by trained observers. The Observer brings structure and reliability to this process.

  • Allows researchers to define, code, and analyze behaviors on a synchronized timeline
  • Integrates video, audio, physiological data, and eye tracking
  • Ensures reproducible coding with interrater reliability statistics
  • Generates visual summaries that highlight behavior frequency and duration

The Observer turns complex social behavior into clear, reliable data that strengthens every stage of autism research.

EthoVision: Objective tracking of behavior

EthoVision is the most cited video tracking system in behavioral research. It automatically measures movement, social approach, and exploratory activity, giving scientists rich data without human bias.

  • Tracks activity, position, and interaction with complete objectivity
  • Analyzes animal and human behavior in the same platform
  • Handles long recordings and large sample sizes efficiently
  • Provides consistent results that can be compared across experiments

EthoVision gives researchers an accurate, unbiased way to measure activity and social behavior, transforming every movement into meaningful, reliable data.

FaceReader: Understanding emotional expression

Baby FaceReader is perfect for studying autism

Emotion recognition and expression are central to autism research. FaceReader automatically analyzes facial expressions, providing a precise timeline of emotional responses.

  • Detects six universal emotions plus neutral and contempt
  • Measures facial muscle movements with millisecond accuracy
  • Enables detailed analysis of mimicry, intensity, and timing
  • Includes Baby FaceReader for developmental research in infants

FaceReader gives researchers a powerful way to quantify emotion and expression, turning subtle facial responses into meaningful, reliable insight.
