What is this field?

The field of Developmental and Educational Psychology focuses on changes that occur across the lifespan and how we learn. This field has been in existence since the 18th century with the works of Watson and Rousseau, leading up to the popularly controversial work of Sigmund Freudopen in new window and the revolutionary Charles Darwin. Development occurs in many stages, with leading minds such as Piaget and Erikson attempting to classifyopen in new window these stages.1-2 Advancements in this field have led us to understand that development continues across the lifespan, that we do not stop developing after childhood.3open in new window

What do these researchers study?

  • Preferential looking
  • Classical conditioning
  • Developmental milestones
  • Play-based learning
  • Attachment and temperament
  • Self-concept (“mirror test”)

A popular concept in this field is the ever-debated nature versus nurture argument, with modern minds understanding that both are necessary to shape who we are. Researchers also examine concepts such as developmental milestones, attachment and temperament, and the concept of self. The latter is often studied using the Mirror Testopen in new window which involves showing an infant a mirror and waiting to see if they notice a mark placed somewhere on their body.4 Stability versus change, another hallmark question in this field, is often accomplished by running large-scale longitudinal studies such as the 1958 National Child Development Study.5open in new window

How can Labvanced match these famous designs?

While developmental studies are commonly performed in labs, there are many advantages to shifting to an online setting. Developmental researchers using Labvanced have utilized the following features, among many others:

  • Infant and child-friendly eye tracking and head tracking settings: Labvanced offers special eye tracking settings tailored to the attention of infants and young children. For example, calibration targets can be set as cartoon pictures of animals with accompanying sounds and the Virtual Chinrest can be disabled for younger infants.
  • Audio/video presentation: In your study, you can add objects that present audio or video files to the participant. These can be controlled with any trigger, even eye tracking.
  • Audio/video recording: Labvanced can also record the participant’s voice or voice and camera image. Aside from collecting this as data, researchers have the option of presenting the recording to the subject within the study.
    • Example: The Mirror Test - have the parent/guardian place a dot on the child’s nose. Run a study in which the child is recorded via the device camera with the video feed being displayed on the screen like a mirror.
    • Check out the video in new window
  • Longitudinal Studies: Pre-set the dates and times that your participants should be asked to return for the next session of your study.
    • Example: Studying working memory in children aged 5 and following their development until age 10.

What are the advantages of online experimentation?

  • Longitudinal studies are easier when you can pre-plan sessions and let us handle the email reminders for your participants.
  • Reduced artificiality: Introducing children to a lab setting is problematic because it does not capture a real-life setting; it is artificial and this may influence performance as the child is hyper-attentive to the new surroundings.6open in new window
  • Access vulnerable populations: Children and the elderly are vulnerable populations due to the pandemic 7open in new window
  • Kid-friendly: Children are difficult to bring into the lab due to unique needs, discomfort with strangers/unfamiliar places, and parent schedules8open in new window
