Developmental psychology

Although developmental psychology involves the entire lifespan, researchers mostly focus on the period in which changes follow each other fast, from birth to early adulthood.

Many studies are devoted to children, their education, and development. They explore topics such as children’s basic understanding of the physical world, how children acquire language, how learning behaviors develop, and how they interact socially with other people, for example in parent-child interaction studies.

Research tools for infant studies

The use of video greatly expands the scope of such a research project. That’s why numerous of researchers record video and use Viso® and The Observer® XT to capture infants' behaviors and reactions while they perform a task, are exposed to a novel object, are playing with a sibling or peer, or are having a meal. 

Coding the videos, whether they are made at home or in a lab, enables you to review, visualize and analyze the behaviors quickly. Moreover, The Observer XT seamlessly integrates all your data streams.


Measuring infants’ facial expressions

Since young infants are unable to provide verbal feedback, their facial expressions can provide extra insights that help us to understand their emotional reactions. Baby FaceReader has been developed as a state of the art system to automatically detect infant facial expressions in order to help address questions in developmental psychology related to affect and developmental disorders such as Autism Spectrum Disorder (ASD). It can help analyze expressive behavior occurring in naturalistic and experimental situations and during parent-child interactions.

Tools for infant studies

Today’s researchers have developed a large number of tests and experiments to get a good impression of developmental processes in infancy. Studies aimed at finding out more about language development, attention, controlling movements, social interactions, or learning behaviors in infancy are often carried out using audio and video recordings.

Observe and code playing behavior

Naturalistic observation of infant behavior

Research is often performed in observation labs. You can observe an infant unobtrusively and in a setting similar to their natural environment. In a controlled environment, you can accurately measure exploratory gaze behavior or emotional reactions. 

In a home setting, researchers can use our portable lab, which includes equipment such as video cameras, recording and analysis software, or Pocket Observer, for scoring behavior on a handheld device. Some researchers use eye tracker data together with video recordings to capture the exact gaze of the infant.


Research on developmental disorders

Developmental disorders have a huge impact on someone's life. For example, children with ADHD or autism may have trouble concentrating in school, paying attention to others, and thinking things through. To find answers to their research questions, researchers often compare the behavior of typical development (TD) children to that of children with developmental disorders (DD).

Examples of developmental psychology research

  • The team of researcher Gangi examined prospectively infant gaze behavior at six, nine, and 12 months of age in infants who were later diagnosed with ASD, as well as low and high-risk infants without autism spectrum disorder outcomes.
  • The Centre for Infant Cognition (CIC), at the University of British Columbia, in Vancouver, Canada, looked at minute eye gaze changes, hand gestures, and the emotions of infants while they observed a moral dilemma or social interaction, which was usually depicted in a puppet show.
  • The iCare (Improving Children’s Auditory Rehabilitation) project is a network of young researchers working in the field of communication concerning children with hearing impairment.

White paper Autism Research

Research on Autism Spectrum Disorder (ASD) has increased enormously over the years, and has resulted in new understanding of how to set up different types of therapy, detect ASDs early in life, stimulate developmental processes, and so much more.

In this paper, we will describe how and why observational research methods are used in autism research worldwide and thus try to answer two questions: why should we observe behavior, and how can we observe behavior in a structured way?

Parenting behaviors and executive function in Down syndrome

Understanding more about developmental delays in Down syndrome is vital in developing targeted interventions. In this study, the relationship between parenting behaviors and executive function was examined.

A closer look at eye contact

Infant siblings of children with or without ASD participated in a study to determine whether gaze behavior showed during a test with an unfamiliar examiner could predict gaze behavior in a more naturalistic context.

Comparing two different skin-to-skin contact techniques

Skin-to-skin contact is essential in developing a feeling of safety, and in creating the bond between parent and child, especially with premature babies. Buil et al. compared two different kangaroo positioning techniques.
